FISHES OF GREAT BRITAIN AND IRELAND. B. Anacanthini Pleuronectoidei. The structure of the head is apparently unsymmetrical on the two sides. Family, IV PLEURONECTID.E, Risso. Heterosomata, Bonaparte. Diprosopa, Latreille. Branchiostegals six to eight: pseudobranchise well developed. Gills four. Body strongly compressed, flattened, with one of its sides coloured, the other being colourless or having merely some spots. Both eyes (except in the very young) situated on the upper or coloured surface, sometimes they are rudimentary. The two sides of the head not equally developed, one remaining almost rudimentary. The jaws and dentition may be nearly equally developed on both sides, or more so on the blind than in the coloured. A single, long, dorsal and anal fin. Pectorals when present may be rudimentary. Scales present or absent. Lateral-line on the coloured side single, double, or triple : curved or straight. Air-bladder absent. The members composing this family are commonly known as flat-fishes, bnt it must be observed there are two groups of "flat-fishes." The one being as it were flattened from above, as we see in rays and skates, wherein the upper surface is the back. It is not so however among the Pleuronectidae or "side swimmers," which are flattened from side to side, except the head, which appears distorted and likewise flattened. When referring to the pleuronectoids the terms right (dextraT) or left (sinistral) are employed with reference to the position of the upper or coloured side : to ascertain this the fish is placed with its tail towards the observer, the dorsal fin above and the anal beneath. Reversed examples are such as have the eyes situated on the side of the body opposite to the one in which it is generally seen. Double examples are those in which both sides of the body are coloured. Adams remarked (Voyage of the Samarang) that such as frequent coral reefs often have their tails ornamented with rather vivid colours, and their upper sides marked with somewhat striking patterns ; whereas those that are half buried are as dull and dingy as the surface is where they are found. They are evidently aware how efficacious their colours prove for the purpose of concealment, and when pursued sink down to the bottom, where they lie quite still on the ground, the colour of which assimilates to that of their own upper surface. The Pleuronectoids, or flat-fishes, are among the most remarkable of vertebrate animals, as for about a week or more after birth they swim on edge in a way similar to other fishes, having their dorsal fin above, their anal fin below them, and possessing an eye on either side of the head. But as they grow older this erect position becomes lost, their sides become their upper and lower surfaces, while both eyes are on the superior or coloured side of the body. The adult, when at rest or swimming, usually keeps near the bjttom of the water, and progresses by means of a sort of undulating motion of the whole body, and of the unpaired fins. These fish are of a broad, flat shape, and margined in almost II. 1 74837 2 ANACANTHINI. their entire extent by the dorsal, caudal, and anal fins ; while not only the muscles, but the skin, the gills, gill-covers, and even the pectoral fin-rays are less developed on the blind (or normally under surface) than on the coloured side, the mouth also being, as it were, bent round to this eyeless side, towards which the anterior part of the face seems to be twisted. From a very early age it had been known that these fishes when first emerging from the ova, and while in a pellucid condition, have an eye on either side of the head ; that by degrees the eye, on what eventually will be the eyeless side, becomes depressed, while at the same time a dark spot appears on the opposite side of the head, so that the fish almost seems to possess three eyes. By degrees this dark spot becomes a distinct eye, while that on the other side gradually disappears ; in short, the eye apparently migrates from what is henceforth known as the blind side of the fish. Van Beneden (1853) and many others, considered that this abnormal position of the eyes in adult flat-fishes was due to a greater or less torsion of the entire head on the axis of the body, or else to a twisting of the face alone. Ten years subsequently (1863) Professor Steenstrap, having obtained examples of young flounders, demurred to this explanation. He observed that if such were effected by simple torsion, the nerves and muscles belonging to the upper eye must necessarily pass over the frontal bone of the blind side, and permanently continue in that position, which, however, is not found to be the case, they being at the bottom of the orbit ; and he considered that the eye must have first passed under the frontal bones, and subsequently upwards and through them. The eye, when leaving its original site, attempts to carry the frontal bone of its own side with it, but the greater portion of that bone resists, remaining in its place. Professor Steenstrup consequently came to the conclusion that the eye on the blind side undertakes a movement deeper and deeper, passing under the half roof formed by the frontal bone of its own side, and is thus brought up through its vault ; so that in order to find room for itself, it partially separates one frontal bone from its fellow, and partly makes its way through the substance of the frontal bone itself ; in short, that the eye, in attaining its final position, first passes obliquely inwards, and then ascends upwards through the head, emerging on the opposite side. Professor Wyville Thompson* considered that the eye of the blind side passes to the coloured or eyed-side of the body, not through the vault of the head, but under the integument, displacing in its progress the frontal bone of its own side ; that the space through which the nervous and vascular connections pass is indicated in the mature skull by the unsymmetrical posterior half of the articulating process of the prefrontal of the blind side, the eye having maintained its normal relation to its associated bone, the frontal, of the coloured side throughout. The eye changes but little in actual position with the growth of the fish, the associated parts being, as it were, developed past it and thus pi-oducing this singular obliquity. Traquair (Trans. Linn. Soc. 1866, xsv, p. 263) believed that here we had a real case of asymmetry in the supposed absence of the additional processes of the os frontis anterius and proprium. But Hr. Malmf considered this conclusion to be erroneous, and he observed that the young flat-fish is obliged, owing to the depth of its body, increased by the development of its vertical fins, to remain on one side while resting on the ground, the horizontal fins not being sufficiently developed to sustain it in a vertical position. The eye of the "blind " side has a tendency to turn towards the light, and in doing so carries with it the cartilaginous framework of the skull, which eventually is only apparently asymmetrical. He gives excellent figures of the first stages of these fishes. J Professor Alexander Agassiz remarked that the first change and the process is identical, whether we take a right or a left flounder. First there is a slight advance towards the snout of the eye about to be tranferred : so that the transverse axis, passing through the pupil of the eyes, no longer makes a right angle with the longitudinal axis. This movement of translation is soon followed by a slight movement of rotation, so * Ann. and Mag. Nat. Hist. 1865, p. 361. f Svensk. Vet. Akad. Handl. vii, no. 4, 1868. j See also Gervais, Arch. Zool. Exp. 1877, p. 193, t. vi, and Lacaze-Duthiers, I.e. p. 305. A. Agassiz, Pro j. Amcr. Acad. Arts and Science-*, xiv, 1879, 1 1. vii-x. PLEURONECTID^E. 3 that when the young fish is seen in profile, the eyes of the two sides no longer appear in the same place, that on the blind side being now slightly above and in advance of that on the coloured side. With increasing age the eye on the blind side rises higher and higher towards the median longitudinal line of the head. The dorsal fin gradually extends towards the nostrils, and finds its way behind the eye which has come from the blind side. The eye is transferred at such an early period that the bones of the skull are cartilaginous, and the transfer is carried out by a combined process of translation and rotation. In some cases it was observed to be transferred, as described by Malm, round the head by the snout, and in others to actually pass through the soft tissues of the head, and this divergence appeared to be due solely to the generic differences in the position of the dorsal fin. Some flat-fishes have the eyes normally on the right side of the body, others on the left, but reversed instances, or those in which the coloured side is on that which is as a rule uncoloured, are not uncommon among most genera of Pleuronectoids. Such is very frequently observed in flounders, these fishes, living close in shore, being* more exposed to the actions of currents than those genera which live in the deep sea. In this way they become in their very early life forced on to the side which is not the normal one. Such valuations are more commonly perceived in some localities than in others, and will generally be found due to local disturbing causes. Professor Agassiz kept young flounders in glass vases, raised high above the table, and found that, notwithstanding the fact that here no disturbance could occur, seven out of fifteen were noticed endeavouring to force the eye round the wrong way, by lying down on the opposite side. But all the seven soon died, and this may account for the comparative scarcity of reversed flat- fishes. He also observed that the presence of light on all sides failed to arrest, or even to delay, the transfer of the eye, and the consequent change in the colour of the under side, which invariably became white with advancing age, when that organ passed over to the upper surface. Thus it would appear that the absence of light is not the primary or sole cause of the want of colour on the under side of the flat-fishes. While the eye is progressing from the one side of the head to the opposite where it is to find its final resting place, its course is occasionally arrested, and it may remain permanently stationary on the upper surface of the head, and this is commonly seen in what is known as " double flat-fishes,"* or those coloured on both sides. f Donovan obtained a young double turbot, and thinking he had discovered an unknown fish, termed it Pleuronectes cyclops, and which he figured on plate xc. " So singularly different," says that author, " is this from the rest of the Pleuronectes that it seems to militate even against the chai'acter of the genus, which requires that both eyes should be placed on one side. We were almost tempted, from this consideration, to constitute a new genus for this curious fish." Yarrell remarks, " The Pleuronectes cyclops of Mr. Donovan, I believe to be an example of the young fry of the turbot, the head of which is not perfectly formed." Double fishes have been observed in flounders, turbot, plaice, soles, etc., and they are seen to swim vertically, and to be more frequently found near the surface of the water than those which progress in a normal manner. All who have eaten these double flat-fishes know how they are most deservedly held in greater estima- tion for the table than others which have an uncoloured as well as a coloured side. Then there are albinos or those which are uncoloured or nearly white on both sides (being almost or quite double albinos) and still retaining their normal form ; but in some that have been carefully examined no sexual parts could be detected. * These would appear to be examples in which the ancestral form has been more strongly developed than has the adopted. The early lives of these fishes afford excellent illustrations of these two distinct phenomena, or of ancestral or inherited form and adopted modification. For in the earlier stages of their existence after leaving the egg, they swim on edge with an eye on either side of the head as in other fishes; but in a definite period they assume their adopted form of both eyes being on the same side. No matter through how many countless generations these pleuronectoids may pass, still the embryonic or early fry condition, or an eye on either side of the head, will continue to be apparent, just as the visceral clefts in the human embryo are. t In many double flat-fishes the eves are in their normal position. 1* 4 ANACANTHINI. In the majority of albino examples only patches or portions of the body are thus affected, and it has been suggested whether such may not occasionally be due to a cross having occurred between a normal and a reversed example of the same species giving rise to a sort of piebald colour. Among these fishes it appears as if the female sex largely preponderated over that of the male. It also seems probable that their eggs float when deposited in the sea (see page 27). In the earlier stages of their existence during the spring months, pleuronectoids pass their lives close in shore ; they swim on the surface and appear more active if the wind is setting in shore, per/haps taking advantage of it to return towards home. Many legends doubtless are in existence throughout the universe regarding how these fishes became coloured on one side only. Klunzinger tells us that in Upper Egypt a tradition is prevalent that Moses was once cooking a fish, but by the time it had been broiled until it was brown on one side, the fire or the oil gave out. Moses, in a temper the reverse of amiable, threw the fish into the sea, where, although half broiled, it came to life again, and its descendants have up to the present day preserved the same peculiar appearance, being white or colourless on one side and coloured on the other. In Constantinople a similar story is told of these fishes, but Moses retires in favour of the Sultan, Mohammed II, the conqueror of Stamboul. In the Isle of Man, Patterson states that there is a legend accounting for how the mouths of flat-fishes became twisted ; the finny tribes bethought them- selves that it was time to select a king to decide disputes, and for which purpose they all assembled, putting on their best appearance. The plaice, however, remained so long at home adorning himself with red spots in order to be selected their chief, that he did not arrive until all was over and the shad had been elected " king of the sea." On hearing the result, the indignation of the plaice was aroused, and curling his mouth to one side, he remarked with disdain, " Fancy a simple fish like a herring being king of the sea." And his mouth has continued awry ever since.* In some of the genera forming this family it is very interesting to observe the different plans on which the eyes are modified and protected. Thus, the plaice or the flounder are able to move these organs horizontally, or even vertically, and it appears as if the two eyes, to a certain extent, act independently one of the other. In the turbot this organ can be covered, for not only does a thick skin invest the upper and lateral portions of the globe, as in most of the pleuronectida?, but being insufficient to protect the eye from the irritation of the sand wherewith it covers itself, it is able to elevate a thick lower eyelid, or else to depress the transparent portion of the globe of the eye beneath this fold of skin. Respecting the means of capturing these fishes, it is found that they mostly reside in localities where the beam-trawl can be employed ; while due to their great commercial value for food they are sought for throughout the year. It was observed at Great Grimsby, during the cold winter of 1881, that the catch of soles had increased, as then they retired into deep water. By an old law of the Cinque Ports, no one might capture soles between the 1st of November and the 15th of March : neither was any one permitted to fish from sun-setting to sun-rising, that the fish might enjoy their night's food (Pennant, 1776). Constant complaints are heard respecting the diminution in the quantity of flat-fishes and the undersized ones that are sent to market. Thus, in Land and Water of September 17th, 1881, Mr. Epton remarks on this as a fisherman and what he has observed during the last few years off Great Grimsby. Now these fish have decreased so that the captures by each fishing smack are much less than formerly, but the supply has been kept up by increasing the number of vessels. It has been suggested that beam trawlers ought not to fish in water of less depth than twelve fathoms, or they would be injuring the brood-grounds. Once captured in a trawl, there would be but little use in returning the small fish to the sea, as they are usually too much injured. * The muscles oi' these fishes are more developed on the coloured than on the blind side of the body. PLEURONECTID^E. 5 Dr. Sauvagc lias remarked that the various degrees of development of the termination of the vertebral column in the genera Rhombus, Solea, and Pleuronectes are in accordance with their geological appearance (Compt. Rend., April, 1872), while, geologically speaking, they are a modern family of fishes, having been found in a fossil state in the early Tertiary deposits (Rhombus solea), but no remains of allied forms occur associated with those of the bony fishes of tho Cretaceous and Jurassic rocks. Geographical distribution. These littoral forms are mostly found where the sea possesses a sandy bottom, or else in muddy or sandy rivers, rarely existing at great depths, and but seldom frequenting rocky or precipitous coasts ; while due to the deficiency of an air-bladder they live at the bottom. Pleuronectoids are most numerous towards the tropics, where, however, they do not attain to so large a size as those which reside in temperate or cold regions ; they are absent from very high latitudes. Some, as the common flounder, are anadromous forms, but the majority are strictly marine ; while a few of the marine species have naturally, or consequent upon experiments made by man, been acclimatized in fresh water.

Eye diameter 5| to 6 in the length of the head and nearly or quite equals the extent of the snout, and from f to 1 diameter apart ; anteriorly the two eyes reach to the same level ; interorbital space smooth, scaleless. The greatest height of the head does not quite equal its length. Lower jaw prominent ; the posterior extremity of the maxilla reaches to beneath the middle or hind edge of the orbit ; the length of the maxilla equals about 1/3 of that of the head. Teeth conical, in the anterior two-thirds of the upper jaw in two rows, the outer consisting of distantly separated and large ones : posteriorly a single row ; in the lower jaw six to eight distantly placed conical ones ; none on the palate or tongue. Fins the dorsal commences above the first third or middle of the upper orbit, and terminates before it reaches the caudal fin, the length of the interspace being equal to the depth of the free portion of the tail ; all the rays are simple and unbranched except the last few ; the highest rays are about its centre where they equal about one-third that of the body beneath them, the anterior and posterior rays are short. Pectoral on the coloured side half as long as the head, slightly shorter on the blind side ; Yentral short, being scarcely half the length of the pectoral, while it does not quite reach to above the commencement of the anal, which latter fin is low at first but at about the end of its first third the rays become so long as to be equal to at least 1/3 of that of the body above it, the fin terminates beneath the end of the dorsal, its last few rays bifurcated. Caudal emarginate. Scales minute, and cycloid over the body and head on the coloured side and some on the end of the maxilla, none between the rays of the dorsal and anal fins. Blind side of body scaled. No spine in front of the anal fin. Lateral-line anteriorly curved above the pectoral fin, the height of the curve being about equal to one-fourth of its length. Gill-raliers compressed, wide but short, the length of each not being equal to half that of the orbit. Colours right or coloured side of an olive marbled all over with darker : fins similarly coloured except in the young, when the basal halves of the dorsal and anal are light coloured. Names. Said by Ray (1713) to have been termed but, also turbid or turbot. PLEURONECTID^E. 7 Lady fluke. Turbot, Moray Firth, also bradan leathari or "flat salmon," while at Aberdeen the large ones are called turbot, very old and black ones blacksmiths, and young ones birdies (Sim). Also known as workhouse turbot. Be Heilbot, Dutch. Le Fletan, French. Habits. This is the largest form of the family taken off the British shores. It feeds close to the ground, but often inhabits deep and rocky situations, while Lacepede observed that in Greenland it appeared to prefer localities also frequented by the cod, as they probably seek the same food. Pennant remarked (1776) that during the preceding year there had been two instances of holibuts swallowing the lead weight at the end of lines with which seamen were sounding, one occurring off Flaniborough Head, the other when going into Tinmouth Haven. Thompson took from the stomach of one weighing about 120 lb. the remains of a ray : from another ten full grown sprats and a fragment of Mill&pora polymorphs : another was crammed with crabs and a valve of Venus cassina. On the Dogger bank it is said to consume large quantities of shell fish, also flat-fish and Crustacea. Means of capture. Baits employed on very strong hooks and lines, as it sometimes offers a most determined resistance when hooked, and which may bo very formidable in large examples. This, according to Thompson, is not in accordance with the experience of Irish fishermen, who assert that it is a simple fish, easily killed, and they never lose one in consequence of its weight. Off Ireland it is said to be generally taken on cod-lines, the Bucciniim undatum being mostly employed as a bait. In the Orkneys they are most commonly captured in the slack water and eddies occasioned by the various islands in the race of the tides. Baits. Generally those employed for the cod and turbot. In the Moray Firth a piece of plaice is mostly used. Breeding. April in Cornwall (R. Couch) : off Scotland in the spring (Parnell). The roe is of a pale red colour, and the ova very numerous (Buckland). Diseases. Thompson states that upon all he has examined were specimens of the parasite Hvrudo hippoglossus, Midler ; and Mcintosh remarks that Epibdella hippoglossi is often seen on the caligus of this fish, in fact JJdonella caligorum is common. Uses. Said to be more famed for its size than for its quality, and is sold throughout the year except during May and June. As food. It is little esteemed in England and does not obtain a ready sale among the general public, unless other fish is scarce ; Mr. Rowell, however, observes (Land and Water, July 16th, 1881), that at Newcastle they are termed " turbot " and greatly esteemed, and as a test observes cod is retailed at 4d a lb. ling at 5d or 6d and halibut at lOd or Is, these three prices showing their respective local estimation. He continues : " Let any one get a piece of halibut from a small one, season it with nutmeg, pepper, and salt, and bake it in the oven, and I know nothing so fine no fish, turbot, sole, or salmon, can excel it ; it does not do to boil, it is too soft, I think, and it is too thick to fry, and it does not do to slice it, but cut a piece of three or four pounds or more, and bake it, it makes a most delicious fish dinner." In Cheltenham and elsewhere, Jews are frequent purchasers of halibut, but they must have an entire fish with its head and gills intact. Thompson considered it very good for the table : Low asserted that it is a large, coarse and dry fish, except the head and fins which are reckoned excellent, while a small one is far from bad. The skin is thick and oily, as also the bones, from which latter a quantity of pure oil may be obtained. The Greenlanders are said to cut them into large strips which are dried in the sun. Habitat. From the coasts of Spitzbergen to Iceland, Finland and Scandinavia to the British and French shores, but it is rare in the Channel. One was taken in 1874 at Biarritz, and likewise at Boulogne (Moreau). It is abundant off the Orkneys, especially in eddies or where two tides meet, one captured in such a locality was 7i feet long and thick in proportion ; it is also common in Zetland (Baikie). Frequently met with along the east coast of Scotland (Parnell) : ami 8 ANACANTHINI. thrives on the immense sandy plain between there and Norway (Buckland). Reid has obtained it up to 231 lb. weight at Wick : also found in the Moray Firth, more particularly during the month of March : at Banff in deep water (Edward) : Aberdeen (Sim) : not rare at St. Andrew's (Mcintosh). Resident off the Yorkshire coast and in moderate numbers, but seldom caught now at Flamborough where thirty or forty years ago it was very numerous (Yorkshire Yertebrata). In the Norwich papers of February 15th, 1873, one is mentioned as having been taken off Yarmouth, measuring 5-| feet long, 2~ broad, and weighing 7% stone, and Buckland, another, 6 feet long, weighing 161 lb. obtained from the same locality in 1867. In the Norfolk Chronicle of April 29th, 1876, it is recorded that Messrs. Parker exhibited a halibut from the deep sea off the eastern counties weighing over 300 lb. and above seven feet in length. It has been captured off Sussex (Merrifield) : it is occasionally taken off Devonshire but not sought after (Parfitt) : on April 14th, 1870, one weighing 102 lb. was secured at Mevagissey : it is not common off Cornwall, and has been taken up to 122 lb. off Land's End, and one weighing about a cwt. is recorded by Mr. Cornish in the Zoologist, as captured on a spiller in Moixnt's Bay on May 15th, 1882. Pennant mentions it from the Menai Straits, and in April, 1829, an example 7| feet long and 320 lb. weight was recorded from off the Isle of Man (Mag. Nat.

It is taken occasionally on all parts of the coast from December until March. In Portrush, county of Antrim, it is occasionally captured in winter on the cod-lines, baited either with Buccinuin undatum or the flesh of various fishes, chiefly Labridce (Zool. 1876, p. 4754). The example figured is 26 inches in length and came from the North Sea. It attains to at least 500 lb. weight in Europe. Olasson mentioned one exceeding this from Iceland, and which was said to have been little short of 20 feet in length : while Couch was informed of a still larger example captured on the banks of Newfoundland.

Eyes divided by a narrow but scaled ridge, diameter about 1/4 of the length of the head and nearly 1 diameter from the end of the snout. The anterior margin of each eye is on the same vertical line. Cleft of mouth deep, the maxilla equals nearly half the length of the head, and reaches posteriorly to beneath the middle of the orbit, the lower jaw the longer. Teeth pointed, the anterior being the longest, the front ones are placed somewhat distantly apart and in one row in each jaw. Gill-rakers about 1/2 as long as the diameter of the orbit and placed somewhat distantly apart. Fins the dorsal commences above the first third of the upper eye, but is not continued as far as the base of the caudal fin, its rays are simple, the longest being equal to about three times the height of the body below them, and are situated about midway between the hind edge of the head and the base of the caudal fin. Right pectoral nearly half the length of the head, its rays simple. Right ventral, inserted anterior to the base of the pectoral, consisting of six rays, it is two-thirds as long as the pectoral but does not extend quite to the base of the anal, which latter fin has a short spine directed forwards at its base,* just where it commences on a vertical line beneath the middle of the pectoral : it ends similarly to the dorsal : its highest rays are slightly below the centre of its length and are similar to those of the dorsal fin. Caudal wedge-shaped, its central rays being slightly the longest ; they are bifurcated at their extremity. Free portion of the tail two-thirds as long as high. Scales ctenoid covering head, including jaws and body as well as a row on each * Dr. Giinther says that in this species there is " no spine before the anal fin." Parnell recorded its existence in the examples now in the national collection, and I find one most distinct in my specimens. But it must not be forgotten that the British Museum specimens were only dried skins. 10 ANACANTHINI. fin ray. Lateral-line nearly straight anteriorly, becoming qnite so opposite the hind end of the pectoral fin. Gmcal appendages fonr. Colours on upper surface of a pale brownish gray or sandy : under surface white. Occasionally it is said to be slightly spotted. Names. Rough dab, or long-rough dah : bastard-satfic, Aberdeen : also yelloio dab, Banff : Long-fieul-, and sandsucher, Edinburgh, the last name being due to the erroneous idea that it feeds on nothing but sand : lemon sole, Scotland. De lange schar, Dutch. Habits. It frequents sandy shores, is captured along with plaice and other pleuronectoids, and, according to Parnell, several may be daily seen in the Edinburgh markets from May to July : Pamell found what appeared to be fragments of some species of Asterias in the stomach of one he examined. Cock's specimen had its stomach filled with the shells of Turritella terebra, two-thirds of which contained hermit crabs, Pagurus. Means of capture. It appears to be usually taken with the beam trawl. Breeding. Asserted by Couch to spawn in May and June. As food. Its flesh is said to be sweet and good, but rather dry. Habitat. Atlantic coasts of North Europe and shores of the German Ocean : Bloch appears to have first received it from Heligoland. The first record of the occurrence of this fish in the British seas was by Parnell in 1835 (I.e.) : Yarrell received an example from Dr. Harwood in 1833, captured during the autumn at St. Leonard's, and in the succeeding summer two from Berwick. It is rare off Banff (Edward) : found at Aberdeen (Sim) : frequent during May, June and July, in the Firth of Forth (Parnell) : not rare off Berwick (Johnston) : Sunderland (G. Fox) : inhabits deep waters in the North Sea and is occasionally taken at Whitby (Yorkshire Vertebrata) : Hastings (Yarrell) : rare off Devonshire according to Parfitt : I have received numerous examples from Brixham : Falmouth (Cocks). In Ireland Mr. Todhunter obtained a specimen off Cape Clear in the winter of 1848, and which is now in the Dublin University Museum. The example figured is nine inches in length and was captured at Brixham, along with several more, in the summer of 1880. The largest British specimen recorded measured fifteen inches in length. PLEURONECTID^E. 11 Genus III Rhombus, Cuvier. Scopjlrfhalmus and Bothus, Rafinesque. Psetta, Swainson. Branchiostegals seven : pseudobranchim present. Eyes on the leftside. Cleft of month deep. Teeth in a narrow band without canines in the jaws, present on the vomer. Dorsal fin commences on the snout, most of its rays and those of the anal branched. Gtill 'membranes but slightly united at the throat. Gill-ralcers long and lanceolate. Scales, when present, small. The turbot was formerly preserved by the Romans in salt water ponds, so as to be readily available for the market. The largest appear to have been preferred, and it has been asserted that the Emperor Domitian convened the seriate as to how a mighty fish of this kind should be cooked. Respecting the food of the turbot and flat-fishes generally, it is often difficult to institute investiga- tions, as they are mostly at once disembowelled by fishermen when captured, because after death decomposition rapidly attacks their intestines, and injures the fish in a very few hours. By Act i, c. 28, of George I, a turbot under 16 in. long, brill under 14, codling 12, whiting 6, bass and mullet 12, sole 8, plaice or dab 6, and flounder 7 in. long, were forbidden to be sold. Geographical distribution. North Atlantic, German Ocean, Mediterranean, and Adriatic to the Black Sea. Synopsis of Species. 1. Rhombus maximus, D. 61-72, A. 45-56. No scales but tubercles. 2.

Eyes diameter 1/6 to 1/10 of the length of the head, 1 transverse diameter apart, lower eye 1/2 a diameter in advance of the upper eye and lj to 2 diameters from the end of snout. Not only does opaque and thick skin cover the upper and lateral portions of the eye, but it can raise a thick lower eyelid or else depress the transparent portion of the globe below this fold of skin, while a portion of the iris forms a semilunar veil at the upper part of the pupil. Cleft of mouth deep, oblique, lower jaw the longer, the length of the maxilla is equal to half that of the head. Teeth small, numerous, and in several rows in both jaws. Fins dorsal commences on the snout in advance of the eyes, its rays are branched, at first low they increase in length to just beyond the centre of the fin where they are about half as long as the head from thence they gradually decrease, ending a very short distance from the base of the caudal fin. Pectoral with branched rays, its length equals two-fifths of that of the head. Ventral commences under the throat, its rays simple, the longest equals two-thirds the length of the pectoral. Anal commences slightly before the base of the pectoral, its rays increase in length to the 18th or 20th which are nearly as high as the highest in the dorsal fin. Caudal rounded. The skin on the coloured side is studded with numerous bony tubercles, the blunt points of which are directed forwards, those on the head are smaller than those on the body. Lateral-line with a curve anteriorly, and becoming straight opposite the posterior end of the pectoral fin. Colours superiorly sandy brown covered with more or less distinct dark spots and blotches, these being likewise continued on to the fins, giving them a mottled appearance. Under surface of the body white. Varieties in form. Examples are occasionally met with having a notch or depression at the summit of the head. Mcintosh (Fish. St. Andrew's) figures an abnormal form, and in his account of the fish of North Uist, observes upon one with an eye on either side of its head, as shown in Pleuronectes cyclops of Donovan. Couch instances a turbot coloured on both sides, in which a process 3 inches in length, thin in substance and nearly as broad as a finger, projected from before its eyes, and was not connected with the fin rays. In colour, varieties are numerous, there are such as are partially albinos : also reversed and double ones. On August 2nd, 1874, a double one weigliing 11 lb. was taken at Montrose, where, remarks Mr. Johnson, " we see sometimes in the course of the year two or three of them, and then for years won't see any." It has been observed that these fish from our northern coasts and brought by the Dutch, are darker than those from the S.W. coast of England. Names. Turbot, formerly spelt turbolt. Bod, Orkneys, lioddan or roanfleulc, barncoch (from its round shape) and gunner-fleuk, or fleuh, east coast of _ Scotland. Neill observes that it is termed rawnfieuh or "fleuk in roe," because it is deemed best for the table when in "rawn" or "roe." Brat, turbrat or roddams, Northumberland. In Cornwall, according to Borlase, it used to be termed brett, in an old Cornish journal it is called luggatee. Birt- or byrte-fish or breat PLEURONECTID^. 13 is alluded to in all ordinances as this or allied fishes. Be Tarhot, Dutch: Le Turbot, French. Habits. Freqnents sandy bays and likewise muddy localities : it appears to constantly change its residence, migrating into deep water during cold weather similarly to the soles (see page 40). It is very retentive of life when captured. Its principal food is small fish, crustaceans and molluscs. In an example taken in Torbay, which Mr. Gosden of Exeter, examined when quite fresh, he found Montagu's crab (XantJio florida), the angled crab (Gonoplax angulata), velvet fidler crab (Portunus puber), the long-haired porcelain crab (Porcelanus long ico mils), the olive squat lobster (Galathea squamifera), the spider crab {Stenorynchus phalangiam), brittle starfish (Ophiostrix frag His), and the Eurynome aspera (Land and Water, January 17th, 1880). Pontoppidan remarks that it feeds on young crabs and small fishes, sea eggs or sea urchins, of which it is very fond. Means of capture. At the commencement of the season, trawls, but as the fish retires to deeper water and rougher ground, long lines or boulters are employed : it is taken by trammel and beam-trawl nets. In calm weather when the sun is bright, it may be speared. In County Down they employ a spear 32 or 33 feet long armed at its extremity with an iron barb : the fishermen even drive it down on them when beyond their reach. In many places, fishing for turbot with long lines has had to be discontinued owning to their being destroyed by steam- trawlers, while in several localities these fish which used to be abundant have almost disappeared. It is to be regretted that numbers of the young of these fish are destroyed by trawlers, or inshore nets having a small mesh as used by shrimpers. Baits. These must be very fresh, alive if practicable, and shining if possible : the lampern is deemed one of the best, and largely used by the Dutch. In the Moray Firth, during July and August, it is often taken with herrings or sand eels used as a bait. It will take a slice of fresh fish as those named, also Coitus, haddock, mackerel, pilchard, sand smelt, garfish, and likewise worms, mussels, limpets, or even bullock's liver. Breeding. Breeds in summer : in February 15th, 1882, I found a female with nearly mature ova. This fish has a large number of very small ova, and in a 23 lb. fish which had a roe weighing 5 lb. 9 oz. Buckland found 14,311,200 eggs. Hermaphrodites. Quelch (Proc. Zool. Soc. 1862, p. 473) published a descrip- tion of a supposed hybrid between this fish and the brill, Rhombus laivis. Messrs. Pile reported to Land and Water (November 28th, 1881) from Dublin having obtained a similar hybrid weighing \7\ lb. "It had the ordinary large turbot head, fins, and unusually large ' wings,' but the belly, though quite white like the turbot, had large scales on it not unlike brills, the back was of a very dark colour and covered with small lumps. The fish was fully matured and in splendid condition." Life history. The young turbot would appear to swim for a longer period " on edge " than the generality of our flat-fishes. I received from Mr. Dunn an example captured August 20th, 1880, which was about 1^ inches in length and supposed to be two months old. It showed the eye still in transit passing round the bones of the head. Mr. Dunn considers they are hatched in June or July : for the first month they are quite black and swim on edge like a John Doree. Then their skin commences to mottle with white and brown, and their right eye begins to pass over to the left side of the head. Next they become white underneath, and of a light leaden colour on the upper surface, and during the period they remain of this shade on the back, which is until they have passed two months of age, they swim on the surface of the sea. If they descend to the bottom during this period it can only be occasionally. What the rate of growth of these fish is, very different opinions may be given. Some young, measuring three inches across, were obtained from shrimpers and placed in the Southport Aquarium. In two and a half years they had attained to 10 lb. each in weight, after two years more they further augmented to 20 lb. or an annual average increment of about 4|- lb. each. In the Proceedings of the Zoological Society of London, December, 1879, will be found the result of some observations made 14 ANACANTHINT. on these fishes in Ballinskellings Bay in Ireland, which seemed to point out that the annual increment in the sea was about 1 lb. yearly. Diseases. Mr. Cornish has taken turbot cut in the belly by, presumably, one of the weevers (see Trachmus, i, p. 78). When hooked and on the long lines, the myxine or hag will devour the turbot. Uses. A large proportion of our turbot are taken along our east coast, on or near the various sandbanks. But the Dutch are more successful at capturing this fish than our native fishermen, and are estimated to supply one-fourfch of the quantity of this fish which is consximed. Their fishing commences about the end of March, a few leagues to the south of Schevelingen. As the warm weather approaches the fishery is gradually advanced to the northwards : and the fishing terminates about the middle of August. The Dutch were computed to have realized 80,000 yearly by the sale of turbot to the London markets and the Danes 12,000 to 15,000 per annum for lobsters wherewith to form the sauce (see Fisheries, in Introduction). As food. The most highly valued among flat-fishes. In L'Estange's House- hold Book, sixteenth century, the mei'its of the turbot appear to have been recognized : one is mentioned as purchased for two shillings and fourpence, while ten plaice cost but tenpence (Lubbock). Rutty, in 1772, says it used to be termed in Dublin " the pheasant of the water." Low, in the Orkneys, that it is a much better fish than the halibut. If at all tainted it is liable to occasion nausea and sometimes severe symptoms. This fish is generally boiled for the table, and lemon juice rubbed over it is reputed to preserve its whiteness. Habitat. The coasts of the northern seas of Europe, plentiful in the German Ocean, and extending to the seas of Britain and round the coast of France, and through the Mediterranean to the Adriatic. Low observed that during seven years in the Orkneys he had seen but two or three specimens : not rare in Orkney and Zetland (Baikie) : Banff (Edward) : Aberdeen (Sim) : common at St. Andrew's (Mcintosh) : but large ones are rare until the English coast is approached. A considerable fishery exists along Berwickshire, Northumberland and Yoi-kshire (Yarrell). Resident off the coast in moderate abundance (Yorkshire Vertebrata) : rare in the Norfolk estuary (Gurney) : very fine ones are taken at the back of the " Falls " near Margate (Backhand) : in the vicinity of Dover, the Varna and the Ridge sandbanks, the first about seven miles distant and the latter about twelve on the French coast, also afford good fishing ground at certain seasons for these fish. A considerable amount is likewise captured off the Devonshire coast where, however, it is not so common as off Yorkshire : in Cornwall not uncommon, also captured in the Bristol Channel. In Ireland it is taken round the coast and is plentiful to the north (Templeton) : at Portrush, common (Ogilby). The example figured is fourteen inches in length, from the Yorkshire coast. As to the size it attains in this country, accounts vary, as in some places the halibut is termed a turbot. Thompson mentions one 44 lb. weight captured in a trammel in four fathoms of water at Springvale, County Down. Buckland took a cast of one which weighed 32 lb. Parnell records on hearsay, one weighing 190 lb. and Couch possessed a note of one 70 lb. in weight. 2. Rhombus lsevis, Plate XCVII. Rhombus loevis, Rondel, xi, c. 3, p. 312 ; Gesner, Aquat. iv, p.

Eyes on the left side, the lower 1/2 (1/4 in the young) in advance of the upper : 1 diameter apart. Interorbital space flat. Its eye is not so elevated at its base as in the plaice or flounder, consequently it is not so lateral ; externally it is similar to that of the turbot (page 12). Lower jaw projecting and the longer : the maxilla 2/5 the length of the head, and reaches to below the posterior third or hind edge of the lower orbit ; anterior nostril with a valve ; the posterior open. Teeth small ones in jaws and on vomer, none on the palatine bones. Fins dorsal commences on the snout, its first few rays having broad fringes which divide so as to give them a brush-like appearance : its rays are branched and the longest behind the middle of the fin. Pectoral on coloured side half as long as the head and longer than its fellow. Ventrals not attached to the anal : caudal rounded. Gill-raJcers about 1/2 as long as the eye, thick, about 12 in the lower branch of the outer branchial arch. Scales small, cycloid, continued on to the head and vertical fin rays : no tubercles on the body. No spine before the anal fin. Lateral-Hue with a strong curve anteriorly reaching to some little distance beyond the extremity of the pectoral fin when it becomes straight. Colours of a sandy brown on the left side, usually speckled with white or light dots or spots : fins slightly marbled. Under surface white with sometimes a few black or gray spots along the bases of the vertical fins. Varieties. -Apparent hybrids between the turbot and brill have been alluded to (see page 13). Yarrell figures the deformed head of one of these fish, see also Zoologist, 1855, p. 4596. Double brill are not rare. I obtained one on February 11th, 1881, 2l inches in length from Brixham : also reversed and albino ones are occasionally observed. Thompson mentions an example which was covered over with large, stellate, white markings on a very rich-coloured dark "ground," looking precisely as if a shower of snow had fallen on it. Couch remarked upon having seen an example intensely black, w r ith a few whit3 specks on the anal fin. According to Moreau, some examples of this fish from France 16 ANACANTHINI. would appear to have less rays in the dorsal and anal fins than observed off the coasts of Great Britain. He also remarks upon a Mediterranean variety in which the anterior rays of the dorsal fin are much less branched than is usual. Pleuronectes pavonina, Costa, is the young of this species. Names. Pearl, kite, brett, " brit " in Cornish means " spotted." Upon the coasts of Devonshire and Cornwall it is known by the name of " kite " (Pennant, ed. 1812). Bastard turbot, Moray Firth: siller fluke, Aberdeen: bonnet fluek t Aberlady Bay : used to be termed lug-a-leaf in Cornwall (Willughby). La Barbae, Freuch. Habits. Found in sandy bays, also in deep water, and occasionally enters the estuai'ies formed by large rivers. It feeds on Crustacea, small fish and food similar to that consumed by the turbot. Means of capture. Similar to what are adopted for the turbot. In the Firth of Forth it is mostly taken by the hook, but not so along the Cornish coast. Breeding. Said to spawn in spring (Parnell). As food. Abundant in our markets, but not held in so much esteem as the turbot, yet is superior to the plaice. In Ireland it is most esteemed in spring. Habitat. Coasts of Europe, becoming rarer towards the north. It is found round the British Isles and through the Mediterranean. It is rare in the Orkneys and Zetland (Baikie) : also off Banff (Edward) : it is taken at Aberdeen (Sim) : occasionally in the Moray Firth, while it is abundant at St. Andrew's (Mcintosh). Neill records it at Aberlady Bay, Parnell in the Firth of Forth : while off Yorkshire it is resident and not uncommon (Yorkshire Vertebrata) : Norfolk estuary common (Paget) : it is found generally along the east coast becoming, however, abundant along the south coast. In Ireland it is common round the coast, taken with, but much more abundant on sand banks than the turbot, on the north-east coast at least four to one (Thompson). The example figured was from the south coast. As to the size it attains on our shores, Yarrell states that it rarely exceeds 8 lb. in weight, Parnell 10 lb. while Thompson's finest example was two feet in length. PLEURONECTIDyE. 17 Genus IV Zeugopterus, Gottsche. Rhombus (part), Lepidorlwmbus, and Phrynorhombus, Giinther. Branchiostegals seven : pseudobranchioz present. Eyes on the left side and close together. Cleft of mouth deep. Sharp villiform teeth in a band in either jaiv, present or absent from the vomer. The dorsal fin commences before the upper eye, its rays and those of the anal are nearly all branched. Caudal not united to the vertical fins. The ventrals either free from or miited to the anal. Scales ctenoid. Lateral-line having a strong curve anteriorly. Steenstmp (Overs. Dansk. Vid. Selsk. 1865, pp. 95-112) pointed out that a large opening exists in the septum which is normally situated between the gills of the two sides : that he observed such in Rhombus megastoma, Donovan : R. cardina, Fries. : R. punctatus, Bloch : and R. unimaculatus, Risso, considering this as indicative that all these forms belong to the same genus, he adopted Gottsche's nomenclature of Zeugopterus.

Length of Lead 3|, of caudal fin 7%, height of body 2 in the total length. Eyes on the left side the lower one (which is said to be occasionally provided with a tentacle) slightly in advance of the upper, while they are divided by a narrow elevated ridge, diameter about 1/4 of the length of the head, and 1 diameter from the end of the snout. Lower jaw prominent, cleft of mouth very oblique, the length of the maxilla equals more than half of that of the head. Gill rakers rather widely set and about half as long as the diameter of the orbit. Teeth fine ones in the jaws : none on the palate. Fins the dorsal commences over the posterior nostril, and is continued nearly to the base of the caudal fin, its first ray is setiform, and of varying length, while the highest point of the fin is above the blotch on the posterior third of the lateral-line. Pectoral on the coloured side upwards of two-thirds the length of the head, and having its upper rays prolonged : on the blind side it is much shorter. Ventral not conjoined to the anal : the last fin of a similar shape to the dorsal. Caudal rounded. The fin rays are branched at their extremities, and each has a row of scales. Scales smaU and strongly ctenoid, each having from four to six spines at its posterior extremity. They are continued over the head, jaws, and fin rays. Those on the blind side are also spinate. Lateral-line forms a curve over the pectoral, becoming straight opposite the last third of that fin. Colours reddish brown, covered with large, irregularly placed and dark round spots and blotches, one very distinct being situated at the commencement of the last third of the straight portion of the lateral-line. Under surface white. Dr. Giinther considers this fish the type a new genus Phrynorhombus, Giinther, while Steenstrup remarks that it could only form a sub-genus. Names. Block's topknot. Le Pleuronecte unimactde, French. Habits. These have not been recorded. Means of capture. Trawls and appliances useful for taking flat-fish. Habitat. From the coasts of Denmark, round the British Isles to the Mediterranean, in which sea it is rare, but more frequent off the coast of Italy. Off Zetland one example was procured by Fleming, where the fishermen stated it was not common. Berwickshire (Johnston) : in 1860 one off Redcar, in Yorkshire (Ferguson). Examples are in the British Museum from Plymouth, also Weymouth, from which latter locality Henslow sent it to Yarrell. Cornish obtained one, August 26th, 1880, in Cornwall; while Couch alludes to it from the British Channel in 1863. It is evidently far more rare than Zeugopterus punctatus. Ireland North-east coast, one 4 inches long, taken June 16th, 1838, by Dr. Drummond, dredging within the entrance of Belfast Bay. August 19th, 1844, Mr. Hyndman, dredging in Belfast Bay, between Carrickfergus and Gray point, in from 3 to 6 fathoms water, captured two, each 3 inches long. The example figured is in the national collection. The fish has been recorded up to about 5 inches in length from British waters. B. Ventrals united to the anal. 2. Zeugopterus punctatus, Plate C.

Length of head 3^ to 3f , of caudal fin 7 to 7^-, height of body about 2 to 2j in the total length. Eyes on the left side, upper margin covered by a thick skin, the lower eye slightly in advance of the upper, 1 diameter from the end of the snout, and j to \ of the length of the head. Interorbital space narrow but not elevated. Cleft of mouth very oblique : the lower jaw rather projecting anteriorly. Teeth in a villiform band in the jaws, present also on the vomer. Gill-rakers closely set, the longest about 2/3 the diameter of the eye. Fins dorsal commences on the snout, its anterior rays not so long as the diameter of the eye : they gradually increase in length, becoming longest in the commencement of the last third of the body where they equal half the length of the head : the posterior ones short, and the fin passing beneath the base of the caudal, becomes almost conjoined with the anal, which is similarly turned under the tail. Left pectoral nearly half as long as the head, right pectoral half as long as left. Ventral commencing under the throat, is joined posteriorly to the anal : the skin from this fin passes to the posterior surface of the base of the anal rays, a groove being formed for the vent. Caudal rounded. Scales spinate on the coloured side, present on rays of vertical and caudal fins. Smooth on the blind side. Lateral- line forms a curve over the base of the pectoral fin, after which it becomes straight. Colours of a rich dark brown, having a wide black, light-edged band passing backwards and outwards from each eye. Three or four round black marks on the back, and some irregular dark blotches and occasionally numerous light spots. Jaws blackish. Fins dark brown, with some irregular bands and blotches, more especially on the dorsal or anal. Under surface white. Pennant's figure in his edition of 1776, 1. c, erroneously termed smear-dab, is reversed, due most probably to an artistic error. Varieties. According to Mr. R. Couch this fish is very subject to malformation of the anterior end of the dorsal fin, causing it to form an arch over the eyes. J. Couch observed upon having seen this fish with almost the whole of its upper surface, except the head and a small patch near the tail, without colours or scales, like the lower surface : the border of the dorsal and anal fins yellowish red, and with only two'or three rays having scales ; on the tail the rays extended beyond the border of the membrane. In another instance there was no caudal portion, so that where the dorsal and anal fins were brought closely together the body terminated. Names. Browny in Cornwall : little blade hairy fluke, Edinburgh market. At Penzance I obtained this fish and the fishermen insisted that it was a young brill. Le Pleuronecte Targeur, French. Habits. Frequents sandy bays, with low shelving rocks covered with sea- weed, where it conceals itself. It is very remarkable how difficult it is to find in an aquarium, as it hides itself in the darkest corners. Means of capture. Trammels, or nets set for sur-mullets. In the Firth of Forth occasionally taken in crab-cages. Breeding. " Summer and autumn, and in winter, the young are of about 2 # 20 ANACANTHINI. 1 or 2 inches in length, and may occasionally be found under stones at low water- mark " (R. Couch). As food. Mr. Cornish found its flesh to be excellent. Habitat. From the coasts of northern Eui-ope, round Great Britain to France, where, however, it is very rare. Round the British coast it is by no means rare, and even common off Cornwall. Several examples have been obtained in the Orkneys (W. Baikie) ; it occurs at intervals off Banffshire and along the whole line of coast (Edward) ; Aberdeen (Sim) ; not common at St. Andrew's (Mcintosh) ; Firth of Forth (Smith), where Parnell observes that it is rarely seen except during stormy weather ; off Berwickshire rare (Johnson). Mr. Anderson Smith obtained three examples in 1882 from Loch Creram in Argyleshire. Two examples, taken in February, 1852, at Redcar (Rudd, Zoologist, p. 3504), and a third recorded by Ferguson ; also, in 1836, several found there on the beach, but none for the succeeding eight years (Meynell) ; in fact it is of rare occurrence in Yorkshire (Yorkshire Vertebrata), one at Bridlington on May 27th, 1881 (Boynton) ; the Medway (Henslow) . Along the south coast it has been very frequently taken ; at St. Leonards, in 1872 (Bowerbank, Zool. p. 2996) ; August 23rd, 1865, one at Bovisand, Devon, another March 12th, 1873 (Parfitt), while off that county it is frequent during the spring months (Baker) ; at Weymouth, in August, 1854, a fine example was taken by a trawler (Gosse) ; off Teignmouth, in January, 1843, one 6 inches long was captured in a drift net. I obtained it at Penzance on August 13th, 1881, and heard of many more along the coast, some of which I saw ; in fact Mr. Cornish (1866, Zool. p. 311), recording one taken in May at Penzance, remarked that he had obtained 48 examples since 1858. Bristol Channel (Baker) ; Swansea (Dillwyn) ; Anglesea (Gosden). In Ireland one, 6^- inches in length, was taken March 25th, 1835, at Ardglass, co. Down ; September 30th, 1842, Dr. Ball obtained one, 7-f inches long, off Kingston Pier ; 2 more were purchased in the Dublin market and sent to the University Museum ; in 1865 one was captured in the winter (Blake-Knox, Zool. 1866, p. 5(J8) ; in 1853 another, 5i inches long, at Dalkey Sound, in 8 or 10 fathoms of water, and presented to the Dublin Nat. Hist. Soc. (Kinahan, Zool. 1853, p. 3990). The example figured was from Penzance. In British waters this fish attains to 7 or 8 inches in length. PLEURONECTID^. 21 Genus V Arnoglossus, Bleeker. B ranchiostegals six or seven : pseudobranchice present. Eyes on the left side. Cleft of mouth deep. Teeth small and one or tivo roivs in both jaivs : present or absent from the vomer : none on the palatines. Gill -membranes broadly united below the throat : gill-rakers fine. Dorsal fin commences on the snout and is not conjoined to the caudal. Preanal spines may be present. Scales of moderate size and deciduous. Lateral-line ivith a curve in the first portion of its course. Geographical distribution. From, the seas of northern Europe, through the Mediterranean and the East Indian archipelago. 1.

Eyes on the left side, the lower nearly one-half in advance of the upper, diameter 1/4 of length of head, 1 diameter from the end of the snout, and only divided by a very narrow and ridged interorbital space. Lower jaw prominent ; cleft of mouth oblique ; the length of the maxilla equals nearly 1/2 the length of the head. Teeth in jaws rather small, and in about 2 rows ; some on vomer : none on the palate. Fins the dorsal fin commences in front of the upper eye, and is continued to within a moderately short distance of the base of the caudal fin, its longest rays being in the last third of the fin, most of them and also of anal fin are branched. Pectoral half as long as the head, ventral not conjoined to the anal, which latter fin terminates similarly to the dorsal. Caudal wedge- shaped. Free portion of the tail as long as high at its base. Scales strongly ctenoid covering the head and body, also a row along each fin ray. Lateral line with an almost semi-circular curve above the pectoral fin. No spine before the anal fin. Gill-rakers closely set and about half as long as the diameter of the eye. Colours of a brownish yellow with obscure spots : under side white, some- 22 ANACANTHINL times tinged with red. Donovan mentions one which, he observes, had ten or twelve large dusky circular spots on the back, eight of which formed a circle not very indifferently repi'esented by Mr. Jago in the figure given by Ray. Varieties. Mr. R. Couch remarked that the dark side is mottled in individuals which inhabit rough ground. Couch observed that the Orkney fish were plumper than those from the south coast. Professor Giglioli first drew my attention to Arnoglossus boscii being this species. Names. Whiff, merry sole a term applied due to its active movements when in the water. Carter, lantern referring to its semi-transparency when held up against the light. Sail-fluke, Orkneys. She sole, Belfast ; ox- or white-sole, Dublin. De sharretong, Dutch. Le Pleuronecte megastome ou Garcline, French. Habits. Resides in Cornwall from about 4 to 15 miles from shore, and rarely enters sandy bays. Its large prominent eyes give the impression that its habitat is the deep sea. Off the Orkneys, Mr. Scarth says, it seldom comes to the shore earlier than October or later than April, though it is often driven by storms on the beach entangled among the sea-weed. He tells us the black-backed gulls capture numbers. Dr. Duguid observes that this fish does not take a bait, and he only once saw it caught in a net, but, he adds, off sandy shores and in calm weather it comes ashore spontaneously, with its tail erected above the water, like a boat under sail, whence its name. In these favoured places dogs are trained to catch them ! The period when this fish exhibits its gambols is most frequently before a storm, or when a thaw sets in, according to Mr. Scarth. These accounts, Couch observes, have been confirmed by Mr. Thompson, of North Ronaldshay, in which distant island the fish is not rare. Thompson found a CaUionymus dracunculus 3 inches long, and 3 small Gadi in one ; in a second 3 examples of Merlangus vulgaris 3 inches long ; in a third only shrimp-like Crustacea. Means of capture. The beam trawl, while it also takes a bait along the south- west coast, although it is said never to do so in the Orkneys. Baits. Similar to those employed for other flat fishes, which they take readily, especially a slice of a pilchard or mackerel. Breeding. Thompson, on October 31st, at Belfast, procured one which had just shed its ova, only a few mature ones remaining. As food. Of but little value, or, as Borlase remarked, good for nothing. In the Orkneys, however, Dr. Duguid observes that it is highly prized as an article of food, its flesh being white and firm ; but that it loses its flavour by a single day's keeping. Habitat. Prom the northern seas round the British to the French coasts. It is found in the Orkneys ; is rather rare off Banff (Edward) ; Aberdeen (Sim) ; rare in Berwickshire (Johnston) ; resident in moderate numbers off Yorkshire (Yorkshire Vertebra ta). Has been taken along the south coast, appears to be common off Devonshire and Cornwall. Mr. Dunn observes that it is not uncommon to see 30 or 40 brought in by a trawler in one day. It has been captured off Somersetshire (Baker) ; Carnarvonshire (Donovan) ; Flintshire (Pennant). In Ireland it is occasionally taken from north to south along the east coast. From Down and Belfast single individuals are brought to the Belfast market. It is obtained at all seasons. Bell had it from Dublin and Youghal. During the winter of 1865 it was rather plentiful (Blake-Knox, Zool. 1866, p. 508). The example figured was 10 inches in length. For it I am indebted to Mr. D'Urban, of the Exeter Museum, in the market of which town it does not appear to be uncommon. As to the size it may attain, the four largest Thompson records were from 22 to 23^ inches in length. Donovan observes that one brought to him, October 31st, 1775, was 18 inches long. 2.

Length of head 4|, of caudal fin 6^, height of body 2 f to 3 in the total length. Eyes on the left side, separated by a narrow, elevated and scaleless ridge : lower eye slightly in advance of the upper : diameter 4^ in the length of the head, 1 diameter from the end of the snout. Lower jaw slightly the longer : the maxilla equals 2/5 of the length of the head. Teeth in a single row in either jaw, those in the mandibles somewhat the largest. Fins the dorsal commences on the snout, its first few rays being occasionally somewhat separated one from the others and a little elevated : the longest rays in the fin, which are half as long as the head, are behind its middle, none of them or of the anal are branched : the vertical fins are continued almost to the root of the caudal, which latter fin is rounded. Left pectoral more than half the length of the head. The length of the base of the left ventral wide, extending from the throat to the vent, behind it are two prominent spines. Scales rather lai'ge, deciduous : present on the gill- covers, none on the vertical fins. Lateral-Hue anteriorly with a somewhat semi-circular curve becoming straight opposite the end of the pectoral. Free portion of the tail higher than long. Colours of a brownish or pinkish on the left side : white beneath. Varieties. J. Edward (Zool. 1856, xiv, p. 5065) describes a fish 2| inches long, taken from the stomach of a cod. Dorsal commences in advance of upper eye, not confluent with caudal. V. very small. Anal commences below gill cover. Eyes on left side, even. Scales not large, deciduous. L. 1. straight. Pointed teeth in both jaws. Coloured side flesh-colour, at regular distances on extreme edge of D. and A. fins are seven black spots ? Pleuronectes diaphanus. Has seen three specimens. Black spots present in all. In Yarrell's collection were three species of a fish termed Amoglossus lophotes, Gunther, but whence they came has not been recorded, D. 95, A. 77, L. 1. 60. They appear to be very closely allied to A. laterna. Yarrell (Ed. 1) p. 255, remarks upon possessing a Mediterranean skin of this species. Couch, iii, p. 178, introduces this as a British species. Names. Scald-fish, derived from its appearance when captured, as it then appears as if it had been dipped in scalding water, for not only does slight friction cause its scales to drop off but likewise rubs off its skin. Megrim, Cornwall : Lanthem-fish, Cornwall apud Halliwell : smooth sole. Le Pleuronecte Amoglosse, French. Habits. Of these but little appears to be known, but the majority of British examples have been captured along the S.YV. coast, usually on a sandy bottom and at some considerable depth. It is said to be a favourite food of congers and other large fishes which frequent deep waters. Means of capture. Hoes not appear to take a bait, perhaps due to the small 21 ANACANTHINT. size of its mouth, as well as to its living at depths where only large hooks are tried. It is often captured off Cornwall with the beam trawl. Breeding. Risso observes that in the Mediterranean it is very prolific. As food. It is not of sufficient size to be of use for the table. Habitat. From the coast of Norway to those of Great Britain and Ireland, also through the Mediterranean, in which last locality it is tolerably abundant. Off Banffshire it is very scarce (Edward) : Devonshire not common (Parfitt) : but has been recorded from Plymouth (Hanmer) and Weymouth (Jenyns) : off Cornwall Mr. Cornish observed that it is not common and considers it a variety of the "carter:" one example appears to have been obtained at Swansea (Dillwyn). In Ireland an example was taken off the Galway coast by Mr. Todhunter, September, 1848, which is now in the Dublin University Museum. Has also been taken off the coast of Cork (Ball) : and several from Dingle Bay in 25 fathom water (Yarrell). "Was trawled abundantly off this (Dublin) coast last winter and spring. I saw some hundreds used for baiting crab-pots in the spring " (H. Blake-Knox, Zool. 1866, p. 508). Couch has recorded one 6| inches in length, and observes that it attains to 7 inches. PLEURONECTlBvE. 25 Genus VI Pleuronectes, Artedi. Platessa, Cuvier; Limanda, Microstomus, and Glyptocephalus, Gottsche : Platichthys, Girard ; Clidoderma, Pseudopleuronectes, Brachyprosopon, Bleeker. Branchiostegals five to seven : pseudobranchice present. Eyes on the right side: the upper not in advance of the lower. Cleft of mouth shalloiv. Teeth of a moderate size, in a single or double row in each jaiv, and which are most developed on the blind side : none on the vomer or palate. Dorsal fin commences above the eyes : both pectorals present. Vertical fins not confluent. Scales small or rudimentary. Considerable differences are observable in the species composing this genns, as may be perceived when observing the numerous sub-divisions into which it has been subjected. Irrespective of this, considerable variations are found among individuals belonging to the same species, as has been already remarked upon as a family characteristic (see page 3). While Gill has observed a species in which the male has rough and the female smooth scales, while during the breeding season the teeth are movable in both sexes. As bait for these fishes on foul ground lug- worms and pieces of the flesh of the conger or herring are much used. But the majority along the British coasts are obtained by means of the beam trawl. I shall defer the consideration of this mode of fishing until arriving at the valuable genus of Solea (page 3-7). The British forms belonging to this genus have been thus divided : A. Teeth lanceolate and compressed. a. Lateral-line nearly or quite straight. 1. A spine before the anal fin. 1. Pleuronectes platessa, D. 66-77, A. 50-57. Rough interorbital ridge. 2. Pleuronectes microcephalics, D. 85-93, A. 70-76. Yellowish, blotched with dai'ker patches. 2. No spine before the anal fin. 3. Pleuronectes cynoghssus, D. 102-115, A. 86-97. b. Lateral-line strongly curved anteriorly. 4. Pleuronectes limanda, D. 65-78, A. 50-62. B. Teeth conical, a. Lateral-line with a slight curve anteriorly. 5. Pleuronectes flesus, D. 60-62, A. 39-45. Ossicles at base of dorsal and anal rays. A. Teeth lanceolate and compressed. a. Lateral-line nearly or quite straight. 1. A spine before the anal fin. 1. Pleuronectes platessa, Plate CI.

Length of head 4-, of caudal fin 5j, height of body 2| in the total length. Ei/cs on the right side, the lower one- fourth to half in advance of the upper, nearly 1 diameter from the end of the snout, while the two are divided by a narrow, smooth, ridge. During life they are much elevated. Lower jaw in advance of the upper with a knob at symphysis : the length of the maxilla equals that of the orbit, while it reaches posteriorly to beneath the first third of the eye. The anterior nostril tubular : the posterior oval and patent. The interorbital ridge is continued as several rough tubercles to the lateral-line. Teeth compressed and truncated at their summits, 20 to 24 in the upper jaw on the blind side, those on the other side being few and smaller ; those in lower jaw similar to those in the upper. Gill-rakers few, short, and widely set. Fins the dorsal commences above the middle of the eye, and ceases a little before the base of the caudal fin, the interspace being less than the depth of the free portion of the tail below it : the 35th to the 38th ray the longest, and more than half as long as the head. The pectorals on both sides of equal length and 2/5 that of the head. Caudal rounded. A spine directed forwards is situated just before the base of the anal fin. Scales from 90 to 100 rows, cycloid ; some on cheeks, none between the eyes. None along bases of dorsal and anal fins. Lateral-line slightly curved above the pectoral fin, the extent of the depth of which is less than the length of the pectoral fin : the greatest depth between its straight portion and the anal fin is less than the length of the head. Intestines two short ccecal appendages ; the length of the intestinal tract, in a specimen eight inches long, from the pylorus to the vent was 7 inches. Colours of a chestnut or rich brown on the right side, covered with large orange and sometimes black-edged spots. Varieties. Buckland mentions a variety destitute of spots. Reversed examples are not rare, piebald ones common. These fish rapidly assume the colour of the ground on which they are residing. Canestrini considers Pleuronectes italicus, Giinther, to be this species. Names. Plaice, diamond plaice, Sussex, from its lozenge-shaped spots. Plash fleuk, Moray Firth. Facje or /acq, Anglo-Saxon. De schol, Dutch. La Plie Franche ou Carrelet, French. PLEURONECTID^E. 27 Habits. In the Orkneys, according- to Low, it keeps much to sand banks and muddy ground. During the summer months on the east coast of Scotland it appears to frequent rocky localities, but in February and March seeks sandy places where it can deposit its spawn. In Cornwall it has been observed to select water of a moderate depth, and in May to arrive inshore, also in the autumn it is found in shoals in the quiet bays, but when the frost sets in it retires to the deep. When disturbed it will shoot away suddenly for a short distance, and can work itself rapidly into the sand where it lies concealed with only its eyes being apparent. Has great tenacity of life ; one 10 inches long taken in January lived thirty hours after removal from the water : it was kept ten hours in a very warm room where it lay all the time on a dry plate (Thompson). Thompson found in the intestinal canal of some taken in Belfast Bay, Tellina tenuis, fragments of Mactria solida and Mytilus edulis. In June large ones contained some Aphrodita aculeata, portions of Buccinum undatum, with the remains of Decapod Crustacea, April Lucina radula, &c. In East Friesland it has been toansferred to freshwater ponds where it thrives. Means of capture. Low says that in the Orkneys " a few are caught on small lines made on purpose ; but they are not much sought after." Around the British coast they are taken by lines or beam trawls. Spillers also are shot in sheltered sandy bays, the bait employed being the lug-worm or a mollusc removed from its shell. They are speared in the seas of northern Europe where the water is very clear, heavily leaded doubly barbed spears being employed according to Pontoppidan. Breeding. The plaice appears usually to breed about February and March, but sometimes in autumn and early winter. On February 4th this year, 1882, I obtained a male, which weighed 1^ lb., full of milt. Mr. Jackson, in sending some ova of this fish to Mr. Buckland, remarked that they were obtained from a ripe and enormously distended female in one of the tanks in the Southport Aquarium. The ova ran freely, and at first floated on the surface, but when the vessel was perfectly still they slowly settled to the bottom. The slightest motion of the water occasioned them to float. The young are " first seen in April, close to land, swimming on the surface of the sea, on their edge, with an eye on each side. In about a week after being first seen, they may be found in pools near the shore, about the size of a baby's finger nail" (Dunn). Buckland found that a plaice which weighed 41b. 15 oz. contained 1 lb. 9 oz. of roe, or 144,600 eggs, which were of a large size as compared with those of the turbot. Thompson obtained examples 3 inches long in January, 1835. Life history. The opinion was formerly entertained that the plaice is descended from a shrimp, and Dr. Deslandes investigated the subject. He first placed some of the shrimps in a vessel of salt water, and after twelve or thirteen days he discovered eight or nine young plaice. The next year he placed some of these fish in two different salt-water receptacles, and to one lot he added a few of the shrimps, not so to the other. Both lots spawned, but it was only where the shrimps were that any young were produced. On examining the shrimps, he discovered the ova attached to the under surface of these crustaceans, and he felt persuaded that their maternal care is a necessity for bringing forth the fry. But Lacepede suggested that the shrimps eat the ova of flat-fishes, and some may become glued to their under surface when they are unable to devour them. Comparatively rare as the male is, as already observed, I obtained one full of milt in February, 1882. Respecting how it is that in some localities the number of plaice appears to have decreased (see page 37). As food. This fish is in the best condition about May, and Mr. Mayhew computed that upwards of three millions are annually consumed in London. Off Devonshire its quality, observes Parfitt, depends upon the nature of the ground on which it is captured, for, if muddy or sandy, the taste partakes more or less of either. When from sand it is firm and sweet ; if from mud, the reverse. In Banffshire it is held in little estimation ; it is usually deemed poor as food, but bears carriage well. In Ii-eland, however, Thompson states that it is held in general esteem. 28 ANACANTHINI. Habitat From Iceland, along the coasts of northern Europe, to the British and French shores : what was believed to be this species was recorded extending in diminished numbers into the Mediterranean, and in 1878 for the first time to the Adriatic (F. Trois, Alti 1st. Venet. (5), iv, 1878, p. 321). Found all round our coasts. In the Orkneys and Zetland abundant (Baikie) : Moray Firth common, especially during April : Banff (Edward) : Aberdeen (Sim) : St. Andi-ew's (Mcintosh) : Firth of Forth (Parnell) : Berwickshire (Johnston) : Yorkshire resident, very common, bnt Mr. Mudd informs us that it is becoming more scarce, and that it is fonnd in greatest numbers in or near the Dogger Bank (Yorkshire Vertebrata) : at Great Grimsby its diminution is causing alarm to some of the fishermen : Norfolk common (Lowe) : found all along the sonth coast, the largest said to come from Sussex (Jenyns) : off Mevagissey in Cornwall they swarm in shoals dnring the autumn (Dunn) and Mr. Cornish observes that those from a hard, close, killas sand are usually good, edible fish : those from a loose gravelly sand are valueless. In Ireland it is abundant round the coast ; to the north it is the most common species of flat-fish. At Belfast an example 12 lb. in weight was taken and sent to the University Museum. Although one of these fish, weighing 6 or 7 lb. is a fine example, Donovan and others have recorded it up to 15 lb. weight. 3. Pleuronectes microcephalus, Plate CII.

Length of head 6 to 6, of caudal fin 6, height of body 2\ to 3 in the total length. Eyes the lower slightly in advance of the upper, placed close together, and not 1/2 a diameter from the end of the snout. Jaws of equal length in front : the maxilla not reaching to beneath the front eye. Anterior nostril tubular ; the posterior round and patent. Teeth conical, rather compressed and blunted, from PLEURONECTIDiE. 29 11 to 13 in either jaw on the blind side. Gill-rakers very short : not numerous. Fins dorsal commences above the centre of the upper eye ; its rays are longest in the posterior half of the body, where they equal about 1/2 the length of the head. Pectorals of about equal size, and If in the length of the head. Ventrals free. No spine before the anal fin, which latter is similar to the dorsal. Caudal rounded. Scales cycloid, covering the head (except the snout), body, and minute ones on the coloui-ed surface of the vertical fin rays. No filament on the head. Lateral- line on both sides, at first makes a slight curve, more pronounced in some examples than in others, the convexity of which is above, it is then continued almost direct to the centre of the base of the caudal fin. Colours dull yellowish, blotched, and with dark spots, more especially over the chest and along the base of the anal fin. Dark blotches and spots likewise on the anal, caudal, and ventral fins. A dark base to pectoral, which has also some cloudy markings. On the under surface Pennant observed that it was sometimes marked with fine large dusky spots, but that such were not persistent. Varieties. Thompson took an example similar to Donovan's, March 3rd, 1835, D. 93, P. 9, V. 5, A. 76 ; it was free from spots, obscurely marked on the upper side and vertical fins with many shades of brown, gray and dull yellow : the orange stripe round the base of the operculum being very conspicuous : it and another had. a lemon mark about an inch behind the base of the pectoral on the coloured side. Names. Smear-dab, due to its being frequently covered with slime ; lemon- dab or lemon-sole (Belfast) owing to its colours ; Mary sole, Scotland, Devonshire and Cornwall, in which last county it has likewise been known as hit ; smooth-dab or bastard-sole; town-dab, Hastings; French sole, Youghal ; sole-fleuk, Moray Firth ; sand-fleuh, Edinburgh. Be Tongscliar, Dutch. Le Plie microcephale, French. Habits. Parnell observes that in the Firth of Forth it appears during the spi'ing, but two or three seasons pass when not half-a-dozen of these fish are seen in the Edinburgh market. In 1835 they were unusually plentiful, particularly in February, but after March they were scarcely ever met with. Having shed their spawn about April they retire to rocky ground for the remainder of the year. They feed on shell fish and crustacea. Thompson found a Nereis in one. Means of capture. Beam trawl, and with small hooks. Baits. Soft molluscous animals. Breeding. Spawns in May and June. Thompson found one in roe in March, 1835, but omits to mention if the ova were well developed or the contrary. As food. Thompson considered it " a much better fish than plaice, although not so good as sole nor so sweet as the dab." R. Couch says, " it is but little esteemed as food ;" and Cornish, that it is a very excellent fish. Its body is rather thicker than the common dab, and Yarrell considered its flesh equally good, while Pamell says, some people reject it because it possesses a strong disagreeable tarry flavour, while others believe no flat-fish surpasses it in excellence, the flesh being firm and well tasted. The difference depends upon the period of the year when captured, it being good during December, January and February, and unwholesome during April, May and June. Habitat. From Iceland and the northern coast of Europe to the British Isles and French coast. It has likewise been captured off Kamstchatka (Steindachner). In the Orkneys and Zetland Dr. Duguid obtained one in August, 1848, and Mr. Iverach in July : Moray Firth (Harrison) : Banff, not very common (Edward) : Aberdeen (Sim) : St Andrew's, common (Mcintosh) : Seton Sands and Aberlady Bay (Neill) : during February, March and April, off the Fifeshire coast : Firth of Forth, not common, but mostly seen in spring months (Parnell) : Berwick, not common (Johnston) : Yorkshire, resident and common (Yorkshire Vertebrata) : Norfolk (Lowe) : Sussex coast (Yarrell) : Devonshire (Montagu) : Weymouth, several (Gosse), Cornwall, rather rare (Couch), but I found it to be common : also Brixham and Sussex coast, where it is in season during the autumn 30 ANACANTHINI. and winter months. At Plymouth it is known as " merry sole :" at Hove, as " the kit:" at Penzance, as "the queen " or " queen fish" (Pennant): South Wales (Donovan) : Swansea (Dillwyn). Ireland. " Occasionally taken around the coast, but not in large numbers in any part of it" (Thompson), and at all seasons. Portrush, county Antrim, " not uncommon, as several specimens may almost always be picked out of a night's trawling" (Ogilby, Zool. 1876, p. 4755) : the largest example measured 17 inches (Ogilby).

B. v, D. 102-115, P. 10-12, V. 5-6, A. 86-100, C. 18, L. 1. 115. Length of head 6|- to 6|, of caudal fin 6^, height of body 3j to 4 in the total length. Eyes on the right side, and separated from each other by a very narrow ridge, which is scaleless in small, minutely scaled in large examples : lower eye 1/3 in advance of the upper, and 2 diameters in the postorbital portion of the head. Lower jaw slightly the longer, and with a tubercle below the symphysis. Maxilla 2/3 as long as the orbit, and extending to beneath the front edge of the lower eye. Body very thin, its greatest thickness equalling 1/6 of its greatest height, excluding the vertical fins. Teeth in a single row, compressed, with their crowns somewhat obtuse : most developed on the blind side. Fins dorsal commences over the centre of the upper eye, its rays undivided, the longest being at its middle, where they are 3/5 the length of the head : posteriorly it terminates almost close to the root of the caudal fin, which latter is wedge-shaped. Anal similar to the dorsal, but its middle rays not so elongated. A small spine directed anteriorly is situated in front of the base of the anal fin. Both pectorals with 12 rays, the left 1/2 as long as the head, the right 1/4 longer than the left. Ventrals each with 6 rays, and 1/2 as long as the pectorals. Scales C}-cloid on the blind side, feebly ctenoid on the coloured : some very fine ones over the fin-rays PLEURONECTID^E. 3l in adult examples. Lateral-live with a slightly oblique descent above the pectoral fin, from whence it proceeds direct to the centre of the base of the caudal : it has a dorsal branch on the occiput. Gill-rakers short, spinate, and widely separated. Coecal-appendages two, moderately developed. Colours right side brown, with a gray tint, being darkest about the head. A small blackish mark on the upper half of the pectoral fin. Vertical fins of a grayish slate colour, the anterior dorsal rays tipped with white. Left side white. Varieties. Thompson, when examining large numbers of this species, found in one lot the males, in another the females, almost exclusively prevailed : also that the form of the body and the height of the dorsal and anal fins varied considerably in both sexes. Yarrell described P. elongatus from a somewhat elongated specimen, probably a skin, the height of the body in his figure being | of the total length : Couch, who figured from a skin, shows the height of his specimen as about 3^ in the total length : whereas mine is 3j from a fresh example. Names. Pole or craig-fluke, pole-dab. White sole, county Down. La Plie Cynoglosse, French. Habits. Frequents sandy localities : in some years being much more common than in others. Parnell found small crabs and star-fishes in the stomach of one he examined. Means of capture. The beam trawl. Breeding. May and June. As food. Is considered good by some, especially the French, who esteem it to be equal to the sole. In Dublin it is looked upon as very inferior, and Thompson remarks upon having had it dressed, when he found it a passably good fish, but not at all flavoured like, nor equal to, the sole. Habitat. It extends from the coasts of the North Sea around Great Britain and Ireland to the shores of France. It is also found on the North American coast (Goode and Bean). Mr. Peace records in Land and Water that an example 19-*- inches long was taken in Scalpa Bay, near Kirkwall, in May, 1880, and a day or two after another and smaller one, the only ones he had ever heard of in that locality : Banff, rare (Edward) : Aberdeen (Sim) : Firth of Forth, occasionally obtained during April, May and June. Pamell secured fifteen examples : along the south coast the same author recorded three examples from Brixham, from which locality I received three on January 10th, 1880, and have seen many from there in Mav, 1881, and also since that date. Mr. Dunn has sent it me from Mevagissey, where it is very rare, and Mr. Cornish considers it rare along the Cornish coast. I have also seen a Plymouth example. Higgins obtained two at Weston-super-Mare, and Mr. Baker two at Stolford, in Somersetshire. In Ireland it is found on the north-east, east, and south-west coasts. On April 26th, 1837, six examples, from 12 to 14 inches long, were obtained by Thompson at Belfast, and on March 25th, 1839, about 120 were brought in at one time to the market at Newcastle. They had all been captured by trawling, and about 70 more were said to have been also taken, but this was a quite exceptional take. On May 5th one was captured at Ardglass. The example figured is 9 inches long, and was obtained by Mr. Dunn at Mevagissey, November 6th, 1879. It attains to at least 14 inches in length on the British coast, and Thompson records one 16^- inches long from Ireland. B. Lateral-line strongly curved anteriorly. 4.

Eyes the lower slightly anterior to the upper, diameter 5-- to 6 in length of the head, \ to 1 diameter from end of snout, and separated by a narrow osseous ridge. Lower jaw prominent : the maxilla, which is as long as the orbit, extends to beneath the first third of the eye. Teeth a row of about 22 closely set, lanceolate ones on the blind side. Fins the dorsal commences above the middle of the upper eye, the rays gradually increase in length to about the centre of their number (37 or 40) when they commence decreasing in height : the fin does not reach the base of the caudal, leaving an uncovered space equal to about 1/2 the height of the free portion of the tail. Pectoral as long as the postorbital portion of the head. Ventral not joined to anal. A small spine, directed forwards, at the commencement of the anal fin. Caudal slightly rounded. Scales on coloured side with ctenoid margins, those between the eyes and on the cheeks smaller than those on the body. A row along each dorsal and anal ray. Lateral-line smooth : at its commencement it has a semi-circular curve above the pectoral fin, while it sends a branch over the occiput. Lntestines three or four short ccecal appendages. Colours Brownish, with some cloudy markings and spots : dorsal and anal fin, with whitish margins. Occasionally white spots are seen on the coloured side of the body. Varieties. Thompson observed in some examples he took at Ballyhome Bay (co. Down), in September, that they had a few black spots and markings over the body and fins : also at the base of the dorsal fin about six round white spots at regular distances, and about four similar white spots regularly disposed at the base of the anal fin. Names. Common dab, the term " dab " is considered to be one of contempt, as in Lincolnshire it refers to an insignificant fellow : sattie, Aberdeen (Sim) : salt- water fluke, Edinbm-gh : grey fleul; Moray Firth : grey bach, Portrush, co. Antrim (Ogilby). Be Schar, Dutch: La Limande, French. Habits. Frequents most sandy localities around the coasts, and Parnell found it in shallow water. It feeds on marine worms and small Crustacea. Thompson found in the stomach of one, captured in March, at Belfast, "fragments of one of the bivalve shells, solen (neither of the two smaller species), and of corallines, among which Sertidaria dichotoma was apparent." Johnston remarked that off Berwickshire its favourite food appeared to be the pretty Fecfeii obsoletus. PLEURONECTID^E. 33 Means of capture. Beam trawl ; seine (Montagu) ; hand-lines and deep sea lines, being more easily taken by hooks than any other flat fish. Baits. Marine sandworms and bodies of testaceous molluscs. Breeding. April, May and June. Many as small as If inches long were received from the mouth of the Thames in November, 1880. As food. A high flavoured and excellent fish (Thompson), but if waters are muddy the taste partakes of such ; it is largely eaten among the poor of London and Paris. It is in the best condition from February to April in some places, from August to December in Cornwall. Habitat. From the shores of northern Europe to those of the British Isles, and extending to the coasts of France, being abundant off Brittany and Poitou, but less common in the Gulf of Gascogne. It is found on most parts of the British coasts, being tolerably frequent in the Orkneys and Zetland (Baikie) ; abundant at times in the Moray Firth, also pretty frequent off Banff (Edward) ; Aberdeen (Sim) ; not uncommon at St. Andrew's (Mcintosh) ; common in the Edinburgh market (Neill) ; Berwick (Johnston) ; off Yorkshire it is resident, very abundant, and known as the sand-dab at Redcar (Yorkshire Vertebrata) ; Yarmouth, Norfolk (Lowe). It is by no means uncommon along the south coast, especially Devonshire (Montagu), and very common off Brixham and Cornwall. In Ireland it is not rare round the coast, and has been recorded from Dublin (Rutty) : Waterford (Smith) : Youghal (Ball) : Gal way coast (McCalla) : county Down (Thompson) : Belfast and Strangford Loughs (Thompson) : while at Portrush, county Antrim, it is the most frequent kind brought up by the trawl, rarely, however, exceeding 12 inches in length (Ogilby). The example figured, 10 inches long, was from the south-west coast. It has been recorded off the British Isles, by Parnell, up to 15 inches in length. B. Teeth conical. a.

Eyes less than 1 diameter apart, and the lower slightly in advance of the upper. The eyes are so prominent that they are capable of observing objects on both sides of the head. Lower jaw in advance of the upper. The length of the maxilla equals about 1/4 that of the head, but does not reach to beneath the eyes. Anterior nostril tubular, having a small opening : posterior one oval with wide lips. An obtuse ridge passes from the interorbital space to the lateral-line. Teeth conical, blunted, two rows in the upper and one in the lower jaw : the outer row on the upper jaw of the blind side consists of 15 teeth ; the corresponding row in the lower jaw of about 17. Fins dorsal commences opposite the middle of the upper eye, its longest rays are in the posterior half of the body. Pectorals on the two sides similar, and about 1/4 as long as the head. Ventrals free. A strong spine, pointing forwards, exists before the base of the anal fin, which latter is similar to the dorsal. Caudal cut square. Scales small, cycloid : rudimentary ones on the cheeks. A rounded and rough tubercle between the bases of the dorsal and anal rays. Lateral-line commencing opposite the angle of the mouth, curves round the lower eye, and having joined the interorbital ridge, is continued to the centre of the base of the caudal fin. Ccecal pylori short. Colours vary very considerably, and depend upon that of the ground of the locality which they inhabit, but even then scarcely two will be found to be exactly similar. The colour of the upper side is generally olivaceous-brown, with or without darker blotches. Occasionally examples are very dark, when they are termed sea- flounders. The under surface is white. Young plaice and flounders of equal size may be distinguished, prior to the appearance of tubercles along the bases of the dorsal and anal rays of the latter, by the plaice having distinct scales, whereas they are rudimentary in the flounder. Pleuronectes flesus, P. luscus, and P. Italicus are considered one species by Steindachner (Site. Ak. Wiss. Wien. 1868, lvii, p. 719). Varieties in colour. Double examples or such as are coloured on both sides are not uncommon : also reversed ones. These last the fishermen persuaded Donovan were a distinction of sex : Linna?us, Bloch, &c, considered such to be distinct species. Some are partially or enth'ely albinos. Newman (Zool. xiii, 1855, p. 4596) records an albino-flounder with red eyes. " In 1862 an albino variety was brought to me. Both sides were white, and the fins and eyes pink " (Lowe, Norfolk Faun.). In some there are orange spots somewhat similar but usually less vivid than seen in the plaice. On February 22nd, 1882, I obtained a number from Brixham all having orange spots similar to the plaice, and was informed that this is an appearance peculiar to spring-time. Thompson observes that the examples he examined thus marked were taken in March. Some are of a rosy hue, termed Pleuronectes roseus (Shaw) : or of a flesh-red, with irregularly but distantly placed dark-coloured spots, Platessa camaria (Brown). Higgins (Zool. xiii, 1855, p. 4596) remarks on one he terms Platessa melanog aster, notched above PLEURONECTID^E. 35 the eyes and of a very dark brown colour almost black on botli sides. Newman (1. c. p. 4914) continues that it is a favourite trick of the fisher boys to cut a notch in the place indicated when they catch a flounder too small to be saleable. As the notch heals the edges recede, so the dorsal fin appears to commence further back than is normally the case. Whether this is the explanation of all such varieties is questionable, as it may be due to an arrest of development as observed in the plaice, turbot, &c. Thompson (Proc. Zool. Soc. 1837, p. 60) refers to the malformed head of one resembling Tarrell's brill. Names. Flounder and mud-flounder: flounder lantern, Cornwall: fresh-water fleulc and bigger fleuk, Moray Firth : mayoclc fleuk, Edinburgh : fleuk, Northumber- land, also fleioke and fluck : butt, Yarmouth : sea bag ice, Isle of Man (Crellin) : black back, Belfast Bay. Be Bot, Dutch. Be Flet commwn, French. Habits. It is found round our coasts ascending rivers to far above tidal influence, and is able to live in very impure water. There is not much to say of its habits. Its name flounder has been asserted to be derived from the Swedish word Flundi'a, denoting its swimming close to the ground. Here it buries itself in the sand or soil by working down first one side of the body and then the other, and thus its back becomes covered, while its elevated eyes and mouth remain clear for the purpose of seeing and capturing its prey. In some rivers it is found among stones, or on the side of sandy banks in mid-stream ; but muddy holes are reputed not to be the places where it usually resorts. It will wriggle itself up the sides of posts when under the water, as may be seen any day at the Westminster Aquai'ium, and it retains its hold by means of its vertical fins. It is a greedy and voracious feeder, eating worms, slugs, crabs, young fish, and animal substances. Thompson found in one he examined at Belfast, the remains of Bissoa vivas, and Johnston off Berwickshire obtained from them Pecten obsoletus. That this fish ascends into fresh water is very certain. If we turn to Belonius, De Aquatilibus, published in 1553, we find the flounder described as Passer fluviatilis, vulgo flesus. It is said by Bloch and others that this name was given owing to its colour being similar to that of a sparrow, and because it inhabited rivers. The flounder is found in the sea and at the mouths of all the larger rivers round our coasts, and is common in the North Sea and Baltic. Donovan observed that it inhabits both salt and fresh waters : Montagu that it is taken in the Avon to within three miles of Bath : Yarrell that it exists in the Thames as high as Sunbury : Parnell that it ascends rivers to a considerable distance, particularly when the waters are discoloured and increased in size by heavy rains. Personally I have a recollection of taking flounders with a worm, about thirty years since, from the Severn at Shrewsbury, a little above the English Bridge. Mr. Henry Shaw, the well-known naturalist of that town, observes : " Flounders were caught thirty-five or forty years ago about Shrewsbury, and a long way above, in considerable numbers : but since the weirs about Worcester and Gloucester have been made, their ascent has been stopped. The Peplows (fishermen) used to lay what they termed sprigtail lines for them, in the early spring months, on the sandy places they frequented. This sprigtail consisted of a crooked pin with a double bend, having the form of two knees ; to this was affixed about four horse hairs, and baited with part of a worm. The flounder swallowed it, and, as soon as he began to pull, the pin became crosswise. They used to employ two to three hundred at a time on a long line, and lay them at night time." Were the weii-s on the Severn destroyed, they would immediately remount that river at least to as high as Shrewsbury. Means of capture. Low observes that in the shallower parts of the loch of Stenness he has seen vast numbers taken with a seine net. Thompson mentions having observed a fisherman at the mouth of the Bann using an implement as follows : it was in the form of two sides of a garden reel with a spike which was stuck into the ground : to this about forty yards of line were attached, having a very heavy sinker at its extremity, and hooks along its whole length, which were baited with pieces of crab. By flinging out the sinker the line became carried into the water its entire length. 3* 36 ANACANTHINI. In November, 18G2, flounders at Gothenburg and its vicinity were so abundant after a severe storm on the coast of Denmark that although 2-i millions were captured the sea literally remained full of them : 500 men were engaged day and night in this capture and at last they were unable to salt such a number. Pontoppidan relates that when the fishermen row their boats over sandy ground where the flounders are seen in clear weather lying in heaps together, they drop a line with a heavy lead to it under which a little lance is fixed, which by the weight of the lead sticks into the flounder, and it is pulled up with the line. Baits. The angler finds a well-scoured lobworm much approved of, but they will also take a piece of fish ; the novice has to be warned not to strike too soon, as the worm is sucked in some little time prior to its being gorged, while, owing to the size of the fish's mouth, a small hook has to be employed. In some localities it is found to bite best in the early morning. It lives long after removal from its native element, being very tenacious of life. This makes its carriage and transference to distant places easy. Breeding. It spawns from February to about April or even later. At Mevagissey numerous young were observed in April. Harmer recorded finding 1,357,400 eggs in one 24j oz. in weight : 351,026 in a second of 6f oz. : 225,568 in a third of 3^ oz. : and 133,407 in a fourth of 2| oz. Life history. The development of the eyes of these fishes and the changes the young undergo has been referred to at page 3. Diseases. Lowe mentions having frequently seen specimens from the Ouse " affected with a peculiar skin disease resembling epithelioma large fungous growths cropping out over the whole body the granulations large and roe-like under the microscope consisting of large nucleated cells." This fish is largely eaten by the cormorant and other birds. Uses. In Norfolk it is fished for in order to be used as a bait for the lobster fishery (Lubbock). As food. It is watery, poor eating, and inferior to the plaice, both as to flavour and size ; but authors are not agreed as to whether the marine or river forms are the best for the table, while it has been stated to be equally good from both localities, the flavour depending on the food it has been living on. It is considered nutritive and easy of digestion. Lacepede observes that its flesh is softest in the fresh-water examples, due to their more rapid growth. In this country such as come from the Thames are generally deemed firmest, and superior to those from any other river. Memel, in the Baltic, has long been celebrated for its flounders. The Frieslanders esteem this fish so much that they naturalize it in fishponds. Thompson observes that is is not much esteemed at Belfast. Low considered that if fried it is delicate eatinsr. Habitat. From the coasts of northern Europe to those of the British Isles, while off France it is common in the Channel and along Brittany, Poitou, the Gulf of Gascogne and Arachon (Moreau). This fish is abundant around the British coast and is especially partial to the mouths of large muddy creeks : when not impeded by artificial or natural obstructions it ascends rivers long distances. It inhabits all the bays and creeks of the Orkneys, especially if the ground is flat and sandy : abundant in the Moray Firth, ascending the Lossie nearly as high as Elgin (Gordon) : is pretty frequent off Banff (Edward) : Aberdeen (Sim) : abundant at St. Andrew's (Mcintosh): during July and August captured in large numbers in the Firth of Forth in the salmon nets particularly above Queensferry, as well as in Leith harbour with the hook (Parnell) : Berwick, common (Yarrell) : resident in Yorkshire along the coast and rivers, in whioh its ascent is mostly stopped by weirs : every year in the Babble from May to September : common in the Norfolk estuary : down the east and along the south-west coast and Bristol Channel : common round the coast of Ireland (Thompson). It attains to about 8 or 9 inches in length and 4 lb. weight. Donovan recorded one 4^ lb. and Pennant another of 6 lb. PLEURONECTIDiE. 37 Genus VII Solea (Klein) Cuvier. Monochir, Cuvier. MonocJiirus, Yarrell. Cleft of mouth narrow, hoisted round to the left side. Eyes on the right side, the upper being partially or entirely in advance of the lower. Nostrils variously formed. Dentition most developed on the blind side, ivhere the teeth in the jaws are in villiform rows, none on the vomer or palate. The dorsal fin commences on the snout, and is not confluent with the caudal : pectorals present or absent. Scales small, ctenoid. Lateral-line straight. This genus has been subdivided : A. Pectorals developed, Microbaglossus. a. Nostrils on blind side not dilated, Solea. b. One of the nostrils on the blind side dilated and broadly fringed, Pegusa. B. Pectorals on both sides rudimentary or small, Buglossus. C. Pectorals absent, Aseraggodes. Geographical distribution. All temperate as well as tropical seas, except the southern portion of the south temperate zone, and though normally a marine and littoral form, still some enter fresh waters in which they have been acclimatized, and thriven. On retaining some in fresh and others of a like weight in saline water, the first at the end of a year were found to have increased at twice the rapidity of those which were kept in salt water. Among the flat-fishes annually captured around the British coast, none exceed the sole in value as food, while they are esteemed both by rich and poor. Their value is often enhanced by the locality they come from, thus Torbay, Folkestone and other places are more or less famed for the quality of the fish which are taken from their waters. A most important subject, and one which deserves a more searching investigation than it has yet received, is whether the fish are decreasing in quantity around our coasts, and, if so, the reason ? To illustrate one side of this question I give an extract from a letter from an east coast fisherman which speaks for itself: "It is well known among fishermen that there is a falling off in the supply of plaice and soles to an alaimiing extent, whatever may have been said to the contrary by smack-owners and fish salesmen. To explain this, I shall have to carry you back to the time when we first went to fish off the Sylt, about ten years ago ; at which time very nearly all the ground from Horn Reef to Heligoland was covered, as it were, with shoals of small plaice, and intermixed with these plaice were a good many soles, both large and small. We have got as many as eighty baskets of small plaice and ten baskets of soles for one night when we first went there, and very nearly all the plaice would be thrown overboard, and you may be aware that they always die after they have been hove on board a trawler. These fish are so small that I have counted two hundred and fifty in one basket, such as we use at Grimsby. The small plaice that are brought to London market are the largest picked out, and then the others are thrown away. Now, we have fished there every summer, heaving big bags of small plaice on board and throwing them away for the sake of the soles, till by destroying the young brood, full-grown plaice have grown very scarce. At the present time very small plaice will sell well, so that now the soles have grown scarce off the Sylt, the small plaice, being saleable, make up, so you see they are bound to be caught unless stringent measures are taken for their preservation. You must remember that the quantity has decreased during these last few years, twenty baskets being the most 38 ANACANTHINI. you would get for a night now. My opinion of the matter is this, that as the ground from Horn Reef to Langeroog, within a less depth than twelve fathomB, is a natural nursery for young brood, if the wanton destruction of it continues as it has done, we shall soon find it extremely difficult to find even a moderate supply of full-grown plaice, but if stopped I have no doubt that both they and soles would be more plentiful. It is to the interest and benefit of everyone in the fish trade that no English trawler should be permitted to fish within the above depth." Mr. Mann, writing from Bournemouth to the Field, in April, 1882, observed, " I have just weighed a sole of one ounce, and a turbot of four ounces which were exposed for sale here. They were selected from many others of like size. Sixteen pounds' weight were captured on one occasion, the largest not exceeding eight ounces. The bulk were taken in long-shore nets, known as ' tucks,' of small mesh, from which nothing can escape ; but this form of net does not kill the fish, which ought to be at once returned to its native element." Small turbots and soles are often placed in the bottom of the pads and boxes sent to the London markets, but the bulk of them are sold in the towns and villages along the sea coast. It has again and again been brought prominently to notice, especially about the fishing grounds of the North Sea, that the supply of soles taken in British waters is yearly decreasing as evidenced by the trawlers having to go further out to sea, that an increased number of vessels capture only an amount similar to what formerly were obtained by fewer boats manned with less hands, and likewise that the fish supplied to the markets consists of such as are much smaller than used to be the case. Mr. E. Jex, of Billingsgate, remarked (January 7th, 1882), " there have been during the past year some thousands of boxes of soles in this market from Yarmouth, Lowestoft and Ramsgate, while not more than one-fourth of the contents of each box consisted of fish that ought to have been caught three-fourths of each box nothing but slips and tongues." When at Weston-super-Mare in 1879 some new trawling ground was tried, and the large size and quantity of these fishes that were taken amply recompensed the trawlers. But such localities are often over-fished and soon become exhausted and thus quantity has to be made up by those of a smaller size. This is possibly what is found to occur in most places. Thus, Mr. Dunn observes, that his father was the first fisherman who employed a beam trawl in Mevagissey Bay : he captured enormous numbers of fish, so much so that he kept a record, which has, unfortunately, been lost. When the Plymouth trawlers first commenced their operations in new localities off the south-west coast (which was about the time the Calif ornian gold-fields were discovered), they termed their new grounds " California," as illustrating the amount and value of their captures. It has been pointed out by Mr. Epton and others, that a large fleet of smacks towing over the same ground will in a short time clear off the fish which are there. But the main cause of the diminution in the North Sea is generally asserted to be due to the numbers of undersized fish which are wantonly destroyed in shallow water, or their natural brood-grounds by trawling smacks, steam trawlers and shrimp catchers, more especially by smacks along the German coast during the spring and summer months. But while it has been proposed to legislate for this state of affairs by prohibiting the exposure for sale of soles under 6 inches (7 inches, Buckland) in length a difficulty arises which would first have to be investigated. Thus at certain seasons the " thick-backed sole," Solea variegata, which rarely exceeds 6} inches in length, is common in the Plymouth markets, and perhaps finds its way to London ; while the " little sole," Solea lutea, abounds along the south- west coast, and is generally thrown overboard as useless, or sold as manure. Any prohibition against the capture of soles under a certain size would cause taking these forms to be penal. This opens up the question what, if these small forms alone are permitted to increase off the south-west coast, will be the effect on the food of the Pleuronectidce in general ? For should the useless forms be protected and if they live on the same diet as the useful table sole, it appears as if such legislation might cause more injury than benefit to the fisheries.

Length of head 5 to 5|, of caudal fin 7-j to 8, height of body 3 to 3]- in the total length. Eyes the upper slightly in advauce of the lower : interorbital space somewhat concave and exceeding 1 diameter of the eye in width. Jaws of about the same length in front. Cleft of the mouth extends to beneath the middle of the lower eye. Some short filaments on the snout and on the blind side of the head. Nostrils on coloured side just in front of lower eye, the posterior one patent with a thick lip on the upper side : the anterior one tubular. On the blind side the anterior nostril is above the centre of the upper lip and scarcely tubular : the posterior nostril is as far behind the anterior as the latter is from the end of the snotit, it is patent with slightly elevated edges. Teeth small, but distinct on the blind side. Gill-ralcers rudimentary. Fins the dorsal commences in front of the upper eye. The two pectorals of the same size, and 2\ in the length of the head. Ventrals free. Caudal rounded. Scales ctenoid, and continued on to the fin-rays. Lateral-line straight. Colours brown or gray on the coloured side, frequently blotched with black. Vertical fins with a narrow, white, outer edge. Pectoral usually with a black blotch in its outer half, which is very distinct in the young. " The colour of the sole depends upon and varies according to the quality and depth of the feeding ground : (at Weymouth) there are four prevailing varieties : (1) a dark sole ; (2) a shrub sole, from the markings on the back having the appearance of shrubs ; (3) a lemon sole ; and (4) a spotted sole. No. 1 is, I believe, caught in the shallowest water ; no. 2 next ; and nos. 3 and 4 in the deepest water." (W. Thompson, Zool. 1851, p. 3375.) Steindachner I.e. observes that Solea azevia, Capello, from Portugal, is this species. Varieties. M. Capello states that examples from the coasts of Portugal vary in the number of their fin rays from D. 85-95, A. 74-78 (Journ. Sc. Matt. phys. e. nat. Lisbon, no. ii, 1867, p. 164). Near the mouth of the Ouse a variety is taken termed cardine, its head is large and elongated, but its flesh is rather coarse. Reversed examples are not rare (I obtained one from Brixham 14 inches long in January, 1881), neither are double ones or such as are coloured on both sides. On February 11th, 1881, 1 obtained from Brixham a double sole Hi inches in length, with the eyes placed as normally in this species. There are also semi-albino or piebald specimens. Thompson observes that those from the north of Ireland vary considerably in form and colour, some being narrower than others, and tapering more towards the tail. I obtained an example 12 inches long from Brixham in which the caudal fin had been lost, and a new one formed continuous with the dorsal and anal. Names. Sole, as the Greeks considered it would form a fit sandal for an ocean nymph : slips, or tongues, the market terms for the young : also tongue-soles in the Moray Firth, and lobsters in Suffolk. La sole commune, French. L>e Tong, Dutch. Habits. Appears to prefer sandy or gravelly shores, and is retentive of life, but rather uncertain in its migrations, for although mostly appearing at certain spots almost at a given time, and usually decreasing in numbers by degrees : in other seasons they disappear at once as suddenly as they arrived. " The finest soles have been taken," observes Andrews (Zool. 1853, p. 3848), " in the Arun River, miles above the tideway, and where they breed and remain throughout the year." " In the estuary of the Humber," observes Mr. Eagle Clarke, "they are captured from May until August inclusive, all are either in spawn or shotten. The young are very numerous in the shallow water at the edge of the tides." Yarrell, on the authority of a correspondent, remarks that they breed in the River Arun, frequenting it from the mouth five miles upwards, which is nearly to the town of Arundel, and remain in it the whole year, burying themselves in the sand during the cold months. It is not unusual for them to ascend rivers to some distance, while they will live and thrive in fresh water. Along our sea-coasts they retire to the deep as frosts set in, revisiting the shallows about May if the weather is warm, their migrations being influenced by temperature. Although very large examples are occasionally taken in Lynn Deeps this fish, similar to the whiting, only attains about 2/3 the size off Norfolk and Suffolk that it does off Devonshire. PLEURONECTID^E. 41 In Ireland (October) Dr. Farran found Cardium elongation abundantly, a few Bulla apart a, and a number of Echinocyamus pusillits. (November) Amphidesma Boysii, a Dembalium, and a few Amphidesma prismatica. (December) Amphidesma prismatica, a Lysteri, an Anomia, and Donax trunculus. The sole lias been reputed to eat the eggs and fry of other fishes and sea urchins, &c. Means of capture. Generally the trawl. The principal English trawling ground lies from Dover to Devonshire. They may be taken by spillers, but are not commonly captured with hooks : it is suggested that one reason may be that spillers are mostly used by day, whereas the sole is a night feeder. In-shore trawling, shrimping and fine meshed netting during the spring months occasion great injury to the young of these fishes, as do also hose nets set for shrimps. Mr. Welton, of Bridgewater, purchased all the fish taken in two of these nets in one day, and thus obtained 18 cwt. of the fry of soles, plaice, herrings, whiting, &c. Baits. Major Holland (Sc. Gossip, 18/2, p. 261) employs soft- or soldier-crabs, lug-worm, mussel, shrimp and rag-worm, with long gut snoods, but these fish feed mostly at night, and the most favourable time is after a blow, when the water is thick, while a land breeze answers better than a sea breeze. Breeding. They spawn late in the year and during the spring months. I have obtained them in full roe this year up to April 15th. A sole of 1 lb. weight carries about 134,000 eggs (Buckland). Hermaphrodites. Have been recorded by Yarrell. Life history. The very young swim on edge as has been already referred to, but they do not appear to be commonly found so far out at sea as some other species. They are first seen along our south coast about the end of March or commencement of April. Diseases. Buckland mentions having received a sole in which its entire lower surface was studded with hairs from 1/8 to 1/2 an inch in length. On a microscopic examination being made they turned out to be the hairs of the " sea mouse," Aphrodite aculeata. Uses. The skin of the sole was much used, according to Parnell, for fining coffee, being found a good substitute for isinglass : also as a material for artificial baits. As food. The flesh of this fish is white, firm, and of excellent flavour, those from the deepest waters being generally preferred : during the time of breeding, and for a short period subsequently, they are soft and watery. Those on the west coast and to the south are larger as a rule than those towards the north of these islands. May hew tells us that London requires annually 97,520 soles, while that market is principally supplied from the Norfolk coast and the English Channel. Habitat. It extends from the seas of Scandinavia and the Baltic southwards, round all the coasts of France, and is found in the Mediterranean. It is taken in the Orkneys and Zetland, but is rare (Baikie) : it is not very common off Banff (Edward) : but found off Aberdeen (Sim) : is common in the Moray Firth, but not much sought after : frequent at St. Andrew's (Mcintosh) : sparingly at the mouth of the Firth of Forth (Parnell). Resident and common off Yorkshire. Has once occurred at Goode, in the estuary of the Humber, near the mouth of the Ouse (Yorkshire Vertebrata) : the Great Grimsby fishermen assert that they capture most of their small soles off the Dutch coast. Common in the Norfolk estuary (Lowe) : abundant off the south coast from Sussex to Devonshire, and common off Cornwall. Also found in the Bristol Channel, and generally around Great Britain. In Ireland soles occur all round the coast, while Ogilby observes that they are common at Portrush, and Thompson remarks that those in the north vary considerably in form and colour from those more to the south. As to the size it attains Thompson's largest example was 20 inches in length. Mr. Grove, of Charing Cross, received one from Torbay on February 1st, 1882, 24 inches long, and which weighed 6|- lb. A correspondent of the Field alludes to one weighing 7\ lb. captured at Bridgewater, on June 4th, 1881: and casts of a pair from Ireland which weighed together 12 lb. are in the Buckland Museum. Yarrell mentions one 26 inches long and very thick, the largest he had ever heard of, which was brought to the Totness market, and weighed 9 lb. 42 ANACANTHINI. B.

Length of head 5-*- to 6|, of caudal fin 8 to 8f, height of body 2f to 2|- in the total length. Eyes the superior 1/2 in advance of the inferior : about 1^ diameters from the end of the snout, and about 1 diameter apart. This species is rather thicker than S. vulgaris. Upper jaw slightly longer than the lower but not produced into a lobe. The cleft of the mouth extends to beneath the middle of the lower eye. Some filaments on the snout, very numerous on the blind side of the head and also on the few first dorsal rays. Nostrils on the coloured side tubular, the anterior one being the longer. One of the nostrils on the blind side is nearly circular, very wide, and encircled by short and branched filaments. Teeth distinct on the blind side. Fins the dorsal commences in front of the upper eye : most of the fin-rays branched. The two pectoral fins are equally long and 2\ in the length of the head. Gill-rakers absent or exceedingly minute. Scales ctenoid, continued on to the fin-rays. The mucous membrane of the gullet has longitudinal folds which are continued into the stomach : the intestine beyond the pylorus is wider than the stomach : externally both have several large papillas on them. Colours of an orange or lemon yellow, marbled with darker and covered with numerous small black blotches and dots, among which are some light or even white ones. Pectoral fin with a large black blotch, surmounted by a light ring in its posterior half. Vertical fins of the same colour as the body. In some examples the yellow colour is entirely lost after they have been a few weeks in alcohol, leaving the fish gray marbled with darker. Yarrell appears to have been the first British author who distinguished this fish and considered it identical with Pleuronectes pegusa (Risso) : Jenyns, however, observed that it is not Risso's fish, and appears to be undescribed by any foreign authors. Richardson next located it as Pleuronectes nasutus (Pallas) : while subsequently Dr. Giinther believed it to be undescribed and named it Solea aurantiaca. It seems to be S. lascaris (Risso) as suggested by Moreau, and agrees with S. lascaris (Bonap.) : while Steindachner identifies S. lascaris (Risso) with S. scriba (Val.). Names. The lemon sole from its colour : sarid-sole from the localities it frequents : French sole. Borhame, Northumberland. Le Sole Lascaris, French. Habits. Frequents sandy bottoms and appears to be captured throughout the year, a good number were daily in the Cheltenham fish shops from April until December, 1881, and January, 1882. Means of capture. Usually by the trawl, it has been thought by some authors that it prefers deeper water than the common sole. PLEURONECTIM]. 43 As food. It is not in request for the table, being tasteless and wanting in firmness, but is occasionally slipped in amongst such as have been prepared for fi lletting at the fishmongers. Habitat. From the shores of Great Britain and Ireland, through the Mediterranean, and is found off Nice and Naples (Giglioli). Rare in Banffshire (Edward) : Northumberland : resident and not uncommon in Yorkshire (Yorkshire Vertebrata) : found off Sussex. Occasional in Devonshire (Parfitt) : I have seen large numbers from Torbay : Weymouth two examples (Gosse, Zool. 1854) : rare in Cornwall (Cornish) : off Somersetshire (Baker) : occasionally taken in the weirs at Swansea (Dillwyn). In Ireland numerous examples were captured from one place off Galway in 1848. It attains to 14 inches in length (Buckland) ; the one figured was from Brixham, and measures 8^ inches. B.

Eyes on the right side, scarcely half a diameter apart, and 1 diameter from the end of the snout. The upper eye one-half in advance of the lower : interorbital space scaled, anterior nostril tubular. Teeth very minute. Fins dorsal commences above the front edge of the upper eye, and nearly reaches the base of the caudal fin, its rays are branched and the highest are opposite the middle of the length of the body. Right pectoral fin very short, not equalling the length of the orbit : left pectoral still more minute. Ventral not attached to anal, which latter fin terminates similarly to the dorsal. Caudal somewhat rounded at its extremity. Scales ctenoid extending on to the fin rays. Lateral-line nearly straight. Free portion of the tail about three times as high as long. Colours of a rich chestnut brown with six or seven vertical dark bands which are a little more than one-third the width of the interspace between each. These bands become broken up with advancing age, but may even be seen in large specimens mostly as dark marks at the bases of and passing on to the dorsal and 44 ANACANTHINI. anal fins. Caudal with a dark band in its last third, having a light outer edge. Dorsal and anal fins usually edged with white. Thompson observes Solea lingula and S. variegata are brought together as synonymous by Yarrell and Jenyns. " In placing individuals together the most obvious differences appear in the dark blotches and transverse bands of S. variegata contrasted with the comparatively uniform tint of 8. lingula : the scales of 8. variegata are very much smaller and its eyes being relatively to each other placed more vertically : in the dorsal and anal fins being rather more distant from the caudal fin : and in the general form of the body, which tapers less towards the tail : the rays too of the dorsal and anal fins are considerably fewer in number than in 8. lingula." The Banksian copy of Pennant has the following MS. remark : " This fish is sometimes taken at Torbay in the trawling nets. It differs at first sight from the common sole in the edges of the scales being strongly ciliated, and in wanting the numerous small beards that hang from the lower side of the head of the common sort." This appears to be the "red-back " described from E. Hanmer's MS. in the 1812 edition of Pennant (iii, p. 313, pi. xlviii) but there is no reference to this figure (P. Z. S. 1849, p. 83). Names. Thichback, Devonshire, so termed owing to its being thicker than the common sole : bastard sole, Weymouth. It was first observed from our coast by Donovan, in April, 1807, when it was brought to Billingsgate market. Habits. On the south coast of Great Britain it appears in the spring and continues through most of the year. Means of capture. Trawling, and is often taken in very great numbers along the south coast. As food. Largely consumed in Devonshire and Cornwall where it is held in great estimation. Habitat. From the British coasts to France and the Mediterranean, and common off Italy (Giglioli) : frequent along the coasts of France and extends into the Mediterranean, Trieste (Giglioli). Met with occasionally off Banff (Edward) : off Rothsay and the Isle of Bute in Scotland (Scouler) : in October, 1851, Mr. Hussey (Zool. p. 3282) observed upon many having been captured at Brighton, one pair weighing upwards of 6 lb. : but Mr. Thompson (Zool. p. 3375) says they were merely varieties of the common sole, continuing, " the true variegated sole I have never seen exceed 5|- inches (French measure) and I have seen twenty pairs at a time and not half-an-inch difference in the whole lot, and many of them had roe. They are called here (Weymouth) ' bastard soles.' " During August, 1881, 1 found they were being landed in thousands at Plymouth from the trawlers and sold as " thickbacks," they had been captured during at least the three previous months. Mr. Dunn, in the last week in February, 1881, forwarded to me one with the information that they were being taken near Plymouth in hundreds, averaging about six to a pound, and were being sold in pads separated from the other soles as offal. In Ireland one was dredged at Belfast, June 16th, 1838, by Mr. Drummond, and in Ventry harbour it is not uncommon (Andrews) . The example figured is 6^- inches long, and was obtained at Plymouth, it attains to 9 inches in length according to Buckland. 4. Solea lutea, Plate CVIII, fig. 2.

Eyes on the right side, rather close together, the upper being one-third in advance of the lower. Cleft of mouth extends to beneath the middle of the lower eye. Anterior nostril tubular. Teeth pointed and minute. Fins Dorsal commences on the snout before the upper eye and ceases close to the base of the caudal fin, its rays are branched and the highest are opposite the middle of the length of the body. Right pectoral very short, its upper ray twice as long as the others, left pectoral still more minute. Ventral rays two-thirds as long as the first few of the anal fin, which latter terminates similarly to the dorsal. Caudal somewhat rounded at its extremity. Scales ctenoid extended on to the fin rays. Lateraldine nearly straight. Colours right side of a stone gray covered with numerous small brown or dark spots, also three or four rows of moderately sized dark blotches placed very wide asunder, but sometimes entirely wanting. Dorsal and anal fins colourless, but every here and there a ray (from the fourth to the seventh) quite black, portions of others also dark, and some dark spots along the bases of these fins. Caudal spotted. Pectoral with a black blotch in its centre. Some of the specimens described by more than one author as belonging to this species, appear to be small examples of the " variegated sole." Varieties. If the colours shown in Couch's figure are correct, are the proportions such as he copied from nature ? I think he must have had some other species under his eye than S. minuta. Names. Little sole : Bed sole. Le Microdrive Jamie, French. Habits. Appear to resemble those of the " variegated sole." Means of capture. Trawling. Uses. Parfitt observes (Fauna of Devon, p. 28), " sometimes taken in large numbers in the trawl nets : but as they are of no use for the market they are thrown again into the sea." Habitat. From the shores of Great Britain and Ireland to those of France and through the Mediterranean. Off Banffshire it is more common than the "lemon sole" (Edward): common at St. Andrew's (Mcintosh). Reputed to have been taken at Whitby (Yorkshire Vertebrata) : common at Weymouth (P. Gosse) : Mr. Cornish records (Zool. 1873, p. 3697) capturing a star-fish in August, holding one of these fishes, three inches in length, in its feelers. An example was captured in November, 1880, ten miles at sea off Mevagissey, and sent to me by Mr. Dunn. In Ireland it is taken on the N.E., E., S. and West coasts. Ball obtained it in Dublin : McCoy observed (Ann. and Mag. 1841, vi, p. 408) that he found it tolerably abundant in the Bay between the lightship and the harbour : McCalla took it in county Down, and Thompson mentions three dredged off Dundrum in the same county. The example figured, life size, came from Mevagissey : the largest specimen I have obtained is 4j inches in length, but it is said to reach to 5 inches. 4G PHYSOSTOMI. Order HI PHYSOSTOMI, Mutter. All the fin rays articulated, with the exception of the first in the dorsal and pectoral, which are frequently more or less ossified (some genera belonging to the family Sternoptychidse have a rudimentary first dorsal fin). Ventral fin when present abdominal and spineless. Air-bladder when existing having a pneumatic duct (except in the family Scombresocidae). Family, I STERNOPTYCHIDiE. Margin of the upper jaw formed partly by the premaxillaries and partly by the maxillaries, both of which are provided with teeth. Opercular bones not fully developed. Gill opening wide: pseudobranchise present or absent. An adipose dorsal fin may be present or rudimentary. Body scaleless or scaled. Rows of round luminous bodies along the lower surface of the abdomen, and occasionally some also on various parts of the body and head. Air-bladder when present, simple. Eggs enclosed in the sac of the ovaries, and excluded by oviducts. These fishes are all of small size and appear to be mostly pelagic, 'while some may be abyssal forms. This family has been subdivided into three groups by Dr. Giinther, who, however, failed to detect scales in Maurolicus, in which genus they are present, but deciduous. The divisions would consequently have to be altered as follows : Group A. Pseudobranchise present: a rudimentary spinous dorsal fin Scaleless. StemoptycMna. 1. Argyropelecus. A single row of teeth in the jaws. Group B. Pseudobranchise present : no spinous dorsal fin. Scaled. Coccia. 2. Maurolicus. Lower jaw prominent. Group C Pseudobranchise absent : no spinous dorsal fin. Scaled. Chauliodontina. The two forms of this family, Argyropelecus and Maurolicus, which have been obtained off the coasts of Great Britain and Ireland, in common with some other pelagic forms found elsewhere, possess eye-like spots of a circular form which are either impressions or prominences on the skin. Their uses have been a fertile subject for speculation, and possibly much still remains to be discovered. MacCulloch remarked that considering at a depth of 800 or 1000 feet, the light of the sun ceases to be transmitted in the ocean, it may be that animal luminousness is a substitute for that light, and if so these organs would take the place of minature lanterns. Professor Reinhardt observed of Astronethes Fieldii, Val., which is common in the Atlantic Ocean between 23 and 6 north latitude, that in two instances he captured the fish alive, when he saw that it sent forth two strong and vivid greenish lights, which intermitted momentainly and ceased altogether when the fish died (Zool. 1854, p. 4300). Dr. Guppy (Ann. and Mag. Nat. Hist. March, 1882, p. 202) remarked that on November 7th, 18bl, latitude STERNOPTYCHID^E. 47 35 17' south, longitude 17 43' east, two Scopeli were caught; one had some life remaining and displayed a faint, though an undoubted luminosity in the pearly bodies of the pectoral region : direct irritation had no effect. Professor Leuckart, in 1865, suggested whether some at least might not be regarded as accessory organs of sight, a position shown by Leydig to be untenable. In 1879 Dr. Ussow (Bull. Soc. Moscow, liv, 1879, p. 79) of St. Petersburgh, remarked that among these fish belonging to seven genera which he had examined these organs could be arranged in two series : the first he regarded as constituting accessory eyes, the second as special glandular organs. Leydig, in 1881 (Die augen. Organe der Fische, Bonn.), added another group, viz., mother-of-pearl like organs, which are not sensory in function, and he considers they bear the closest resemblance to the electric, or pseudo-electric organs of other fishes, with probably a secondary illuminating function. Group A. Pseudobranchias present. A rudimentary spinous dorsal fin. Body scaleless. Genus I Argyropelecus,* Cocco. Pleurothysis, Lowe. Branchiostegals nine : pseudobranchwe present. Head large, it and the trunk elevated and very compressed, the latter passing suddenly into the tail which is narrow. Eyes large, directed upwards arid outwards, separated by a very narrow interspace. Cleft of mouth vertical and deep, with the lower jaw prominent. The margin of the upper jaw is formed of the premaxillary and maxillary, ivhich have a single roio of fine teeth, a row also in the lower jaw. First dorsal short, preceded by an osseous plate formed from neural spines: adipose dorsal, if present, rudimentary. Pectorals well developed. Ventrals small. Gill-openings wide : gill-rakers long. Body covered tvith a silvery pigment but no distinct scales. Humeral arch and pubic bones prolonged into flat, pointed processes, which project along the median line of the abdomen, intermediate between ivhich are some scutes. Air-bladder present. Four pyloric appendages. Examples of this genus are said to have been dredged in the Challenger expedition at 1100 fathoms, a statement upon which discredit has been thrown. In the Mediterranean it would appear not to be found at very great depths, and may be a night feeder, at which time it ascends to the surface as is seen in the Scopelidce. Geographical distribution. Atlantic Ocean and Mediterranean. One species has been found off the coast of Norway. 1. Argyropelecus hemigymnus, Plate CIX, fig. 1. Argyropelecus hemigymnus, Cocco, Griorn. Sc.

Posterior to the vent the caudal portion of the body becomes abruptly narrowed, while it is everywhere compressed, its greatest width merely equalling 1/4 of its height. Caudal fin 1/5 of the total length. Eye high up, directed outwards and slightly * From some error, Agaseiz thought this might he the young of Zeus faber. 48 PHYSOSTOMI. upwards. The interorbital space very narrow, 1 diameter distance from the end of the snout, and a like distance from the posteinor end of the head. Posterior inferior angle of preopercle, with two triangular spines, the upper directed backwards, the lower downwards. Cleft of mouth deep, the lower jaw projecting beyond the upper, and the posterior angle of the maxilla armed with a triangular spine. Gill-rakers very long. Teeth in a single row of somewhat incurved ones, largest in the mandible. Those in the premaxillaries are directed somewhat backwards, as are also a patch in the contiguous and posterior part of the maxilla, but those in the posterior half of this latter bone are directed upwards. Fins the dorsal consists of two portions, the anterior being prolongations of about 6 neural spines, the last two being the longest and largest, they are connected together by a thin plate : the rayed portion is higher than the first part : a rudimentary adipose dorsal fin is sometimes present. Pectoral rather longer than the head : ventral small, anal somewhat similar to the rayed part of the dorsal : caudal forked. Skin of the body covered with a silvery pigment, while in various places it possesses what have been termed eye-like spots, one anterior to the eye, usually two behind it, six smaller ones on the throat and branchiostegous rays, and six larger ones on the chest and humeral arch : twelve along the pubic plate, and eight on a line a little above this commencing above the axilla, the two anterior of which are the largest. Near the lower edge of the body and behind the ventral fin are four large ones, the last almost reaching the base of the anal, and six more over the last half of the base of the anal fin. Colours the body brilliant silvery, the tail portion yellowish. A few black spots on the head and an irregular band along the base of the dorsal fin. On the side of the tail above the hind edge of the anal fin are two small silvery spots, with fine black bars radiating from them : a black band at the base of the caudal fin. As a rule the eye-like spots along the lower edge of the body have a black edge. Habits. Of these but little is known. Breeding. Eggs large. Habitat. Atlantic and Mediterranean. An example in the British Museum is stated to have been dredged in 540 fathoms, between Shetland and the Faroe Islands by the Porcupine, along with several other Mediterranean forms in 1869. STERNOPTYCHIL\E. 49 Group B. PseudobranchiaB present: no spinous dorsal fin. Scaled. Genus II Maurolicus, Cocco. Gonostomus, sp. Cocco. Ichthyo coccus, sp. Bonaparte. Branchiostegals eight or nine : pseudobranchice well developed. Body oblong, it and the head compressed. Cleft of mouth deep and oblique, lower jato prominent. Maxilla large and wide. Eyes of medium size. Teeth in a single row in the jaws. Gill-opening wide : gill-rakers very long. Dorsal fin in the posterior half of the body, also a rudimentary adipose Jin. Pectoral and ventral present. Anal fin long, commencing on a line posterior to the termination of the first dorsal, its last rays are concealed by shin. Caitdal forked. Scales very deciduous and large, covering the body : one or two rows of luminous spots along the lower side of the head, body and tail. Coecal appendages in moderate numbers. These fishes appear to belong to the pelagic fauna, and as a rule are only captured off our shores subsequent to considerable disturbances in the deep sea. Daring the early part of this year (1882) storms were unusually prevalent, and Mr. Sim obtained from the beach at Aberdeen about 170 examples. As corrobora- tive proof it may be mentioned that Trachypterus arcticus was thrown on shore on February 16th near Berwick, another on April 17th near Flamborough, and four days subsequently a third at Burghead. On Api'il 15th an example of Begalecus Banhsii came ashore in the Firth of Forth, while during the month of April I heard of four specimens of Lcemargus borealis being captured, one in the Firth of Forth and the three others off Aberdeen. The largest of the examples of Maurolicus obtained by Mr. Sim in 1881 had fully developed ova, and they may have been approaching the shore for breeding purposes, because all the large examples of the 170 taken at the same period this year show developed ova and milt ready for shedding : or they may have been on the surface of the sea for this purpose, and so come within the influence of storms. Miiller considei'ed the structure of the jaws of this genus Scopeloid, most correctly observing that the premaxillaries reach to the angle of the mouth, and it is only beyond that angle that the toothed maxillary appears. 1.

Length of head 4 to 4^, of caudal fin 6^- to 7j, height of body 5 to 5 (4j in the young) in the total length. Eye diameter 2f- to 3^ in the length of the head, 3/4 to nearly 1 diameter from the end of the snout, and rather more than half a diameter apart : interorbital space concave from side to side, with a ridge running down its centre. Body and head compressed : the greatest width of the body does not quite equal half its height. Cleft of mouth deep, the maxilla wide and reaching to below the middle of the orbit : lower jaw prominent. Teeth fine ones in a single row in both jaws, none on the vomer or palate. Fins the rayed dorsal commences midway between the hind edge of the eye and the base of the caudal fin : its highest rays rather exceed one-half the height of the body below the fin : the adipose dorsal is very rudimentary, being apparently absent in some examples. Pectoral about half as long as the head. Ventral about as long as one diameter of the orbit, and inserted on a vertical line almost immediately beneath the first dorsal ray, and not quite reaching the insertion of the anal. The anal fin arises on a line somewhat posterior to the base of the last dorsal ray : the first ten rays are somewhat similar to, but rather shorter than, those in the dorsal fin, the succeeding ones are smaller, and the last few in some specimens again increase in size, but owing to their fragility, and being imbedded among the muscles and scales, it becomes extremely difficult to ascertain their numbers : in some I have only been able to discover about 26 in all : in the fine example figured there seem to be 33. Scales cycloid, higher than wide, very deciduous, but distinct : although in the British Museum catalogue it is remarked that there are no regular scales, this is due to their having been abraded, leaving the subjacent silvery pigment visible : still even in the Redcar specimens some can be seen if a magnifying glass is employed. Luminous spots, not elevated but level with the surface of the skin, are very distinct, one on the preorbital, one beneath the chin, one at the posterior angle of the lower jaw : six on the branchiostegal rays : six on the chest, in a line terminating posteriorly at the upper part of the base of the pectoral fin : twelve along the lower edge of the abdomen between the humeral arch and the base of the ventral fin : parallel to this last row and commencing at the upper edge of the base of the pectoral fin, and terminating above the base of the ventral are eight more : six more in a single row between the bases of the ventral and anal fins : fifteen along the base of the anal, and eight more along the lower edge of the body between that fin and the caudal : over the commencement of the anal fin exists a single spot a little higher up than the anal row. Stomach ccecal, with longitudinal well developed ruga? : in those opened no food existed, but small gravel was present in the mouth and fauces : eight large and rather long ccecal appendages : intestines making only two curvatures : testicles and ovaries very long, reaching almost the entire length of the abdominal cavity. Pseudobranchia? well developed. Colours back of a glossy brown or black, with, during life, two zig-zag lighter lines along either side of the back : sides of the head and body of a burnished silvery lustre : a dark band just before the base of the caudal fin : a black mark at the base of most of the luminous spots. Varieties. I have examined numerous examples and find that the number of rays in the anal fin may vary from twenty-six to thirty-seven, owing I suppose to injuries due to friction. No other essential differences being apparent, these scarcely appear sufficient to constitute distinct species. The height of the body in small examples is considerably greater in proportion than that in larger ones. Hutton (Trans. New Zealand Inst, vii, p. 250. pi. xi, f. 90 cl) described Maurolicus Australis, from examples captured at Milford Sound and Cuttle Cove, New STERNOPTYCHIDiE. 51 Zealand, and which he doubtfully separated from M. borealis. Dr. Giinther (An. Nat. Hist. (4) xvii, p. 399) having examined a specimen pronounced it to be Maurolicus amethystino-punctatus, Cocco, from the Mediterranean. Hutton, 1. c. viii, p. 215, states that it is a Gonostoma. The figure gives the impression that the fish is Maurolicus Pennantii. Navies. Pennant first termed this fish the Sheppy argentine, the latter designation gave rise to great inconvenience due to its not being an " argentine." Yarrell proposed the unobjectionable name of " Pearl sides." Habits. Of these but little is known. During their breeding season, or from January until May, they are thrown on our shores in varying numbers and in proportion to the violence of the weather, and it is only in the examples obtained by Higgins in Somersetshire that we possess a record of their capture so late in the season as July. Means of capture. Generally it is thrown on shore by the violence of the sea. Breeding. As the ova, which are large, were ready for shedding in examples captured in February and the milt was similarly forward, it appears that off Scotland they must breed during the earlier portion of the year. Habitat. From the coasts of Scandinavia, to the British Isles, shores of France and through the Mediterranean : off Italy, Giglioli observes, it is rare, but obtained at Niza, and Messina in July and September. Low states that his single example from the Orkneys was given him by a boy, who found it at the edge of the water among the sea ware, since then several specimens have been procured by Dr. Duguid and Mr. Heddle (W. Baikie, Zool. 1853) : Mr. Peach recorded it from Wick : Edward remarked that it is a regular winter visitant off the Banff coast, being never absent during January, and from 1 to 3 inches in length : Mr. Sim h is collected for me at Aberdeen during the last two winters nearly two hundred examples, it being cast on the beach in great abundance during the months of January, February and March : four specimens up to nearly 2 inches in length were taken in April, 1833, from the Firth of Forth (Clarke, 1. c.) : two or three specimens are in the Glasgow Museum : Mr. Rudd first obtained this fish at Redcar in May, 1841 : in 1843 he found thirteen specimens : in February, 1851, four : and in February and March, 1852, forty (Zool. 1852, p. 3504) : it has been taken off Devonshire as recorded by Walcott (Yarrell) : Higgins obtained three specimens at Weston-super-Mare in the month of July (Zool. 1861, p. 7317) : Pennant's specimen came from sea at Downing, off Flintshire. Its capture in Ireland has been reported March 11th, 1847, at Killiney Bay, near Dublin (Thompson, Ann. and Mag. 1847, p. 171). The example figured life-size was taken at Aberdeen by Mr. Sim. Note. Paralepis. Dunn observes, " one of this genus was driven en shore alive by porpoises at Polkerris, near Par, June 2nd, 1869. I sent it to Mr. Couch, who says it is the first known in England. Its length was about 14 inches, depth lg inches. The sides of the fish were of an uniform silvery colour. It was covered with scales, but so delicate that they came off on being handled." 4* 52 PHYSOSTOMI. Family II SALMONIDJE, Midler. Pseudobranchise present. Margin of the upper jaw formed by the premaxillaries and maxillaries. No barbels. Anteriorly a rayed dorsal fin, and posteriorly an adipose one. Pyloric appendages as a rule present, and usually numerous. Body scaled. Head scaleless. Air-bladder large, simple, and with a pneumatic duct. The ova pass into the cavity of the abdomen before being extruded. Geographical distribution. Marine and freshwater forms, some of the former being exclusively inhabitants of the deep sea, others again being anadromons, periodically ascending rivers in order to deposit their spawn. Normally they are confined to the Arctic and temperate portions of the northern hemisphere, with the exception of one species which has been found existing in New Zealand. Some of the genera among the salmonoids furnish most valuable food to the human race r consequently it has been an object to extend their range into the waters of distant lands. In introducing exotic fishes, one of the first considerations must necessarily be to ascertain whether any representatives of the family are normally resident in the region it is desired to stock, and if they are whether the race is a thriving or a diminutive one ; for it has been maintained that if the latter the chances of success are too small to render the attempt worth making, as the region is probably unsuited for their development. By retarding the germination of the ova by means of ice (see Introduction), eggs of salmonidse have been safely carried to Tasmania and elsewhere, and the races successfully introduced. In 1866 I attempted to similarly convey trout into the waters of the table lands on the Neilgherries and adjacent hills in Madras. These mountain ranges embrace a geographical area extending over 268,494 square miles : their peaks vary from 5000 to 8000 feet above the sea, and Ootacamund, where the experiment was tried, is 7426 feet above the sea-level, with an annual mean temperature of 58 68'. Although I failed, two years subsequently Mr. Mclvor succeeded by bringing out the young fish from Scotland, and they have bred in their new home, enabling me to give a figure in the third part of my Fishes of India, published August, 1877, taken from an Indian born trout.* Synopsis of Genera. 1.

Dr. Giinther as editor of the Zoological Kecord, remarked, as " has been foreseen by all acquainted with the nature of salnionoid fishes." And since it succeeded, in his "Introduction to the Study of Fishes," 1880, p. 641, he has observed "the attempt of transferring them into the low streams of India ended (as could be foreseen) in a total failure."

This family of physostomatous fishes is found in Europe, Asia and America, and is most abundant in the Arctic or colder regions, in contradistinction to the distribution of the carps and siluroids, which augment in numbers the nearer we approach the tropics. The groups of salmon and trout are so intimately connected one with another that a common origin to both would scarcely be denied, and here arises the inquiry of whether their ancestors were originally marine or inhabitants of the fresh waters. Several structural reasons appear to point to the sea having originally been the place of their abode. If we look at the salmon we observe that although it ascends into the fresh waters to breed, so soon as it leaves the sea and enters rivers it begins to deteriorate in condition, its flesh becomes softer in quality and paler in colour, while the silvery lustre of the scales commences to change to a more muddy hue. The indigenous species belonging to this genus have been placed in three sub-generic groups, and to a certain extent arbitrarily separated from one another in the following manner : A. Anadi-omous species, with deciduous vomerine teeth, which are usually shed at an early age. Salmo. B. Non-migratory fresh water species, with deciduous vomerine teeth. Fario. C. Non-migratory fresh water species, in which the vomerine teeth are restricted to near the head of that bone. Salvelini. The two first of these groups not being separated one from the other by any impassable barrier, I propose in the following remarks to allude generally both to the sub-genus Salmones or salmons, and trout, leaving observations upon the Salvelini or charrs, until that group comes specially under consideration. Dui"ing the present century much has been written in this country respecting the salmon and the trout, their natural history and economic uses. Founded possibly upon the views of sportsmen, naturalists, and fishermen, laws have been enacted from which but insufficient benefits have accrued, making one reflect whether our ancestors may not have been more practically acquainted with the habits of these fish and the requirements of fisheries, than are the legislators of the present century. It may not be waste of space, when referring to the important family of Salmonidw, first to ascertain what have been the views held by the best known of our later naturalists concerning the species or varieties of true Salmonidce which are found in or around these islands ; for the genus Salmo has been divided into (1) Salmones, or true salmons, wherein the body of the vomer is toothed at some period of their lives, and (2) the Salvelini or charrs, which have the vomerine teeth restricted to near the head of that bone. Donovan, in his British Fishes (1802-1808), referred to the (1) sewen or Salmo cambricus, of which he tells us, among other indicati ins, that the head is shorter than in the common salmon, and the tail more forked this he considered to be an anadromous form peculiar to Wales; (2) the common salmon, Salmo salar; (3) the trout, Salmo fario, which he observed to be subject to many variations. He alluded to that from the Llynteiji, a lake of South Wales, termed Goch y dail, and marked with black spots as large as sixpences ; to a crooked-tailed variety in the Einion, a river not far from Machynllaeth, and also to a similar form being in 54 PHYSOSTOMI. the Snowdon lakes ; to the Gillaroo trout of Ireland, remarkable for the great thickness of its stomach, though it does not otherwise differ from the common trout; and, lastly, to some in Scotch lakes that are spotted very differently from the common sorts, which he suspected to be a distinct species, but of which he makes no farther mention. He likewise alluded to how trout vary in size, and referred to the Fordwich form, in Kent, which attains to nearly that of the salmon ; to the Buddaghs of Lough Neagh, in Ireland, some of which have been known to weigh 30 lb. He also remarked upon trout, the flesh of which was both of the red and white kind, although captured during the same season in two contiguous streams in Cardiganshire, one of which invariably produced the red and the other the white variety. Turton admitted into the British fauna, 1807 (1) the salmon, Sahno salar ; (2) the shewen, Sahno eriox, to which he referred Donovan's sewen; (3) the salmon trout, Sahno trutta; (4) the common trout, Sahno fario ; (5) the white salmon, Salmo phinoc ; and (6) the samlet, Sahno sahnulus. Fleming, in his History of British Animals, 1828, gave first those anadromous forms that have a forked tail, as (1) the common salmon, Salmo salar ; (2) the bull trout, Salmo hucho, which is little inferior to the salmon in size, but more elongated, and has white and insipid flesh, but which he states has no teeth on the vomer; (3) the phinock or white trout, Sahno alius, which seldom attains to a foot in length, and is common in the seas and rivers of Scotland and the North of England. Secondly, anadromous forms with even tails, as (4) the sea trout, Salmo trutta, of which he considered the samlet or parr to be the young of this or of the salmon, the migrations of the two almost coinciding ; (5) the gray trout, Sahno eriox, including S. cambricus, and found in the sea and in rivers. Lastly, forms stationary in rivers, as (6) the common trout, Salmo fario, remarking of the Gillaroo variety that when it feeds on shell-fish the coats of the stomach acquire a thickness similar to the gizzards of birds. Agassiz, Brit. Assoc. 1834, only admitted (1) Salmo salar; (2) S. trutta; (3) S. fario, and (4) the charr S. umbla. Jenyns, in his Manual of British Vertebrate Animals, 1835, included (1) the common salmon ; (2) the bull trout or gray salmon, S. eriox ; (3) the sea trout, S. trutta, inhabiting the sea and rivers, identical with the salmon-trout of the London markets and the white trout of Pennant and Fleming ; (4) the common trout, S. fario, with its variety the Gillaroo ; (5) the great lake trout, S. ferox, which he believed to be identical with S. lactcstris, of Berkenhout, though Agassiz believed not of continental authors. Yarrell, in his History of British Fishes, 1836, gave (1) the salmon ; (2) the bull trout or gray trout, S. eriox and S. cambricus ; (3) the salmon trout, S. trutta; (4) the parr or samlet, S. sahnulus; (5) the common trout; (6) the great lake trout; and in a later edition (7) the Loch Leven trout, S. levenensis. Knox added Sahno estuarius in 1855. Parnell in 1838, in his prize essay on the Fishes of the Firth of Forth, entered very fully into his views respecting the Salmonidw. He admitted (1) the salmon ; (2) the bull trout, S. eriox, of which he enumerates and figures the following varieties which he has obtained in the Firth of Forth: a salmon spotted bull trout, a few spotted bull trout, a thickly spotted bull trout, a large headed bull trout, a curved spotted bull trout, a crescent tailed bull trout, a Norway bull trout, and a salmon bull trout identical with S. trutta of Jenyns and Yarrell ; (3) salmon trout, S. trutta, which is likewise the same as S. albus of Fleming ; (4) the parr ; (5) the common trout ; (6) the Loch Leven trout. Jardine, in his British Salmonidae, 1839, figured (1) the salmon ; (2) the phinock ; (3) the great lake trout ; (4) the common trout and varieties ; (5) the Solway migratory trout ; (6) the salmon trout. "White, in the list of the specimens of British animals in the National Museum enumerated in 1851 (1) the common salmon; (2) the sea trout; (3) the bull or gray trout ; (4) the common trout ; (5) and the great lake trout. Thompson, in his Natural History of Ireland, 1856, gave (1) the salmon, including the parr ; (2) the gray or bull trout, S. eriox ; (3) the salmon trout ; (4) SALMONlDyE. 55 the common trout, including the Gillaroo, which variety he recorded having met with in most fresh water races ; (5) the great lake trout. Dr. Giinther, in a catalogue of fishes in the British Museum, described in 1866 the following anadromous forms: (1) Salmo salar, Vertebra?, 59 (60), Ccecal appendages, 51 to 77 ; (2) 8. argenteus, Ccec. pyl. 61-67 ; (3) S. trutta, Vert. 59-60, Ccec. pyl. 43-61; (4) 8. orcadensis, Vert. 56-57, Ccec. pyl. 50; (5) 8. brachypoma, Vert. 59, Ccec. pyl. 45-47 ; (6) 8. cambricus, Vert. 59, Ccec. pyl. 33-52. And of the non-migratory fresh water forms, admitted (7) 8. levenensis, Vert. 57-59, Ccec. pyl. 49-90; (8) 8.fario, variety Gaimardi, Vert. 59-60, Ccec. pyl. 33-46, variety ausonii, Vert. 57-58, Ccec. pyl. 38-47; (9) 8. ferox, Vert. 56-57, Ccec. pyl. 43-49; (10) 8. stomachicus, Vert. 59-60, Ccec. pyl. 44; (11) S. galli- vensis, Vert. 59, Ccec. pyl. 44 ; (12) 8. nigrvpinnis, Vert. 57-59, Ccec. pyl. 36-42. From the foregoing we find that Donovan, Turton, Fleming, Jenyns, Yarrell, Parnell, Jardine, Thompson, and White admitted the existence of five or six British species of true salmons in our waters, which Giinther increased to twelve, as well as two varieties of the common trout. A thorough investigation into these various forms possesses more than a passing interest, for if we have many species of true salmon and trout in our waters and they interbreed, it first becomes a consideration as to what are the probabilities of sterility occurring in the offspring ? On the other hand, should trout from two apparently distinct species be crossed and no unusual phenomenon occur, except improvement in the breed, while signs of sterility do not follow, the supposition must be raised that we are dealing with local races and not with different species, and that the young are mongrels and not hybrids. Here 1 must shortly allude to how I propose discriminating between local races or varieties and species, for what one naturalist considers a variety another looks upon as a species. I shall consider species among the true salmons to be an assemblage of individuals which agree together in their structure and in the development of the sexes, but differ in some structural character from all other fishes. Also that functionally they are capable of fertile union together, but not to an equal extent or not at all with the members of any other group of fishes. Even within the limits of a single species we find no two exactly similar, but a tendency to divergence from the original type appears to exist, which power of divergence is most likely to preserve and accumulate useful variations. For it has been abundantly proved that artificially, by judicious selection and breeding from individuals which are possessed of some desired variation, such may become permanent in future generations ; while natural selection (perhaps assisted by some unknown factor) would similarly tend to favour the continuation in a wild state of such forms as possess variation favourable to the life of the animal, and thus produce and continue certain local varieties or races. If, however, the variations from the type, present in certain examples, are not of a persistent character, nor exceed the differences between the limits laid down for a species, these cannot be considered as indicating a distinct species ; for to render such valid, we must have a permanence of variation from the original type (see vol. i, p. 245). Thus, among the sticklebacks we find in the ten-spined form some, due to local causes, possessing ventral fins, othei-s destitute of them ; but their difference not being permanent merely resolves itself into a local race or variety. The number of vertebras and the ccecal appendages have been asserted to be constant characters which may materially assist in fixing a species among the Salmonidce, and I propose investigating in detail some of these various structural and functional differences that have been brought forward for the purpose of establishing species among the true salmon, Salmones. Dr. Giinther has pointed out nine constant characters of variation in his elaborate treatment of these fishes, and which I shall commence alluding to as my conclusions differ from those he has so elaborately set forth. 1. The number of vertebrae. The constancy of this character we are told "is truly surprising," as an excess over the normal number by two, or a decrease to the same extent, is of rare occurrence. But the inquirer finds that in the recorded number of these bones in the migratoiy species, the variation has been restricted 56 PHYSOSTOMI. by Dr. Giinther to between fifty-nine and sixty, and among the reputed seven non-migratory forms to between fifty-six and sixty. Occasionally two small vertebrae take the place of one large one, as if a division had occurred ; while in others may be observed an abnormally lai^ge one, as if two had coalesced, as shown by the normal number of hemal spines for two bones being present. Dr. Giinther instances a case " where three vertebrae were united," and Cobbold " of the coalescence of numerous vertebral centra." In a fish wherein these bones normally number about sixty, an extreme variation of five (especially as such has not been proved to be constant) does not by itself appear to be beyond what might be anticipated in a single species ; and inconstant variations would scarcely justify the creation of a new specific name for the reception of such, unless conjoined to other circumstances. Among a number of common trout which I captured at Colesbourne, on the Cots wold Hills in Gloucestershire, some had fifty-seven, others fifty-eight vertebrae ; while in a few received from Cardiganshire I ascertained that this variation extended to between fifty-seven and sixty. As the extreme limits of variation recorded in this country among the common trout have been between fifty-six and sixty, and as these examples of an undoubted single species captured in one locality gave from fifty-seven to sixty, it would seem to be a rash conclusion to formulate species of Salmonidce solely consequent upon an enumeration of the number of vertebrae as ascertained in a few specimens. Only one fact appears to be rendered exceedingly probable, which is, that anadromous forms generally possess an excess of one or two vertebrae over such as are more strictly residents only in fresh waters. 2. The number of coecal appendages. This has been adduced as a character which may materially aid in discriminating a species. If the list of British Salmones already referred to is examined, it will be seen that these appendages in the common salmon may vary between fifty-one and seventy-seven, and in the Loch Leven trout between forty-nine to ninety. (It must be noticed that personally I have observed larger variations than are here recorded, but I have purposely restricted myself to the numbers given in the British Museum catalogue.) These cceca are capable of distension, of subdivision, of amalgamation between two or more, or of being longer or shorter than is commonly the case. The difficulty does not appear in discovering variations, but in determining within what fixed number they exist in a given species. At Colesbourne, I found in the common brook trout already referred to, from thirty-four to thirty-nine ccecal appendages, and up to forty- four in the Cardiganshire examples, the same as in S.ferox. The question forces itself on our consideration whether in any form of trout the number of these appendages are persistent or inconstant, and whether change of climate or food may occasion any variation. Here I must refer to the results obtained from the examination of trout that have been reared in distant localities, but descended from British breeds. Mr. Arthur (Transactions of the Otago Institute, July 9. 1878) refers to the stock of common trout " which were liberated in our streams in November, 1869, and from these and their descendants the ova for stocking the rivers in Otago have been obtained." The original ova came from Tasmania, the trout existing there being the proceeds from three batches of eggs supplied from England through the kind offices of Mr. Francis Francis and Mr. Frank Buckland. They were obtained from streams in Buckinghamshire and Hampshire, and reputed to be the eggs of the common brook trout. The number of coecal appendages is recorded in six instances from Otago, and they varied from forty-three to fifty-four, whereas the limits in the British race is restricted in the British Museum catalogue to between thirty-three and forty-seven. Even were these hybrids, and their existence was pointed out by Willughby, the number of their ccecal appendages would still exceed, by at least seven, any recorded among the British non-migratory forms, except the Loch Leven trout, and are consequently an excellent instance of the inconstancy of their number. Here I must refer to Mr. Senior's observations on these trout, now in a wild state, as he has observed thorn in some parts of Tasmania. Owing to the abundance of winged insects, beet lea, grasshoppers, &c, it seldom rises at the artificial fly ; when hooked it has lost the energy of its ancestors, for after one rush if baffled it SALMONIM]. 57 tamely gives in, while at table it is muddy and coarse, like an English tench. Perhaps were its digestion more rapid its vigour would increase and it seems as if nature is now augmenting the number of its ccecal appendages, and consequently increasing the extent of its intestinal area. As regards the Loch Leven trout, reasons exist for suspecting the race to be more nearly allied to the anadromous than to the true fresh water species. We may thus be dealing with a race that is changing from a marine to a fresh water form, living as it now does in fresh water, but having the colour of a sea-trout. Some examples in the British Museum, captured during the month of April, have the ccecal appendages fewer in number than commonly perceived in the Sahno levenensis, but they are wider than normal, and may be instances of a confluence of two or more into one, but it is suggestive that this character is very inconstant in this species, which seems to be in a transitional condition ; perhaps their diameter will gradually diminish, until in time cceca similar to such as are found in the common brook-trout will be present. Whatever the result of such an investigation might be, it is still evident that the number of ccecal appendages in the various species of trout or salmon is inconstant, and consequently should be most guardedly employed for the purpose of constituting a species. British marine salmonidse possess more of these appendages than do the strictly fresh water forms, while a change of climate to the antipodes seems to increase the necessity for these organs, and as a result in their numbers, in such as are bred there. Here I shall refer to one of the so-called inconstant variations, or changes of colour, such being closely relating to the foregoing remarks upon the Loch Leven trout, the tints of which resemble those of sea forms as much as do the number of their ccecal appendages. Variations in colour must be due to some cause acting directly or indirectly on the fish. Thus, among the young of the members of the Salmonidce, we perceive that dark bands or bars down their sides are almost universal, being evidently hereditary throughout the family. This same banding of the young is seen in some of the horse-mackerel, Caranx, flying-fish, Exoeoetus, the gar-fish, Belone, etc. It has been erroneously asserted that the young of the migratory forms of salmon and trout possess two or three more bars than the non-migratory brook trout. These bars, as well as the black and red spots on the sides, are almost invariably lost in the anadromous forms when they are in a condition to migrate into salt water, and assume their silvery smolfc stage (with or without X-shaped black spots). In rivers it is rare for bands to be retained in adult trout, while most of the black and red ocellated spots as a rule remain, although instances have been recorded in which they have entirely disappeared. In streams where, due to some local cause, the trout are small, it is not uncommon to perceive the bars as well as the black and red ocellated spots retained throughout life. I found this obtained among some from brooks near Penzance ; in fact, they were as brilliant as young parrs, to which, except for the white edging to some of their fins, they bore rather a striking resemblance : in a few instances I have also observed this, but to a much fainter degree, in trout taken at Colesbourne, in Gloucestershire. Examples of brook trout have been found on emigrating to the sea, as a rule (to which there are exceptions), to assume the brilliant silvery livery of the migrating salmonoids, as well as their X-shaped black spots. Mr. Harvie Brown remarked (June 12th, 1882) on having caught at Durness several so-called " sea trout " from a sea pool, or first pool at the mouth of the river, fresh water at low tide, salt or brackish at high tides. From their silvery appearance they are known as " sea trout," but are the river form acclimatized to brackish or nearly salt water, or else periodically visiting the same between tides. Mr. Lockington (American Naturalist, May, 1880, p. 368) observed the same phenomenon in the Western hemisphere, where the Sahno iridens, a resident in all Calif ornian brooks and rivers, descends in the autumn to the sea, and when in salt water changes its colour to a steel blue, while its spots mostly disappear. But although we may generally anticipate the non-migi-atory forms to be more vividly coloured than such as are strictly marine, still among the former there are numerous variations in tints and markings which have been explained in more 58 PHYSOSTOMI. than one manner, as the nnptial season, the effects of temporary emotions, of age, or the state of the creature's health, or its food. It has been observed that a residence in sea or brackish water causes the fish to assume a general silvery or steel colour, with or without black spots, and that these latter are not surrouuded by a light circle. Clear water in rapid rivers or lakes,* especially when the bottom is pebbly, is similarly seen to contain somewhat silvery fishes, with black X-shaped spots. Sir William Jardine remarked that a variety very frequent among trout in small Alpine lochs in Scotland had large dark or red spots placed in a pale or clear surrounding field, these marks being very large, while the principal part of the spotting was confined to the centre of the body. The colour, depth, and character of the water also have an influence on the fish, the presence of moss and peat, or a muddy bottom, usually causing a dark tint, while some captured in dark holes or caves have been seen nearly black. The colours of the tSalmones may be shortly summed up as silvery, with or without black spotsf among the marine, and some resident in large clear pieces of water, as lochs or rivers : more or less speckled with black and red when non-migratory and living in fresh waters : while should the race be small, a persistence of the transverse bars or bands on the body, which are present in most of the young, may be observed even in adults. Irrespective of changes in colour externally, a difference in food may occasion it in the flesh of these fish, whether such alteration in diet is due to choice or to necessity. Thus Crustacea and their allies may be absent from the locality they frequent, or if present the fish may not relish that food so much as some other which exists in the water. In certain rivers there are trout with white and others with red flesh, the two forms being in good health and equally delicate for the table. This has also been observed in the American charr, Salmo fontinalis, introduced into this country, and in which it has been clearly traceable to the food it lives upon. 3. The form of the preopcrcle in adult fish. The shape of this bone varies in species belonging to the true Salmones with the age of the fish, while it has likewise been remarked that in some races the development of its lower limb is much more pronounced that it is in others obtained from different localities. This, however, merely shows that in the marine as in the fresh water races there are fish subject to variations in the shape of this bone. The limb is very short in the young, elongating with age in some forms, but not so in others ; while an arrest of development may easily take place even on opposite sides of the head of a specimen, which were this the sole criterion of species, might, and sometimes does, show Salmo trutta on one side and S. albus, or brachypoma, on the other. Thompson was of opinion that differences in the form of this bone may sometimes be due to sex. 4. The width and strength of the maxillary in adult fish. This will depend upon the food which the fish has subsisted upon during its lifetime. If this organ has been much called into action, it will greatly exceed in size and strength what is found in examples in which it has been less employed. It appears to be almost invariable that the lower jaw is more developed in the male than in the female, besides which in the former it is often provided with a hook at its extremity. 5. The size of the maxillary and of the vomerine teeth. The same remarks are suitable to this form of variation as apply to the maxillary bone. 6. The arrangement and permanence of the vomerine teeth. These vary so * Percy St. John, in Wild Sports of the West, p. 240, remarks that he "' never observed the effect of bottom soil upon the quality of fish so strongly marked as in the trout taken in a small lake in the county of Monaghan. The water is a long irregular sheet, of no great depth, one shore bounded by a bog, the other by a dry and gravelly surface. On the bog side the trout are of the dark and shapeless species peculiar to moory loughs, while the other affords the beautiful and sprightly variety, generally inhabiting rapid and sandy streams. Narrow as the lake is, the iish appear to confine themselves to their respective limits : the red trout being never found upon the bog moiety of the lake, nor the black where the under surface is hard gravel.'' f It cannot be admitted that the black X-shaped spots are due to the influence of salt water, a3 we see thorn present in our strictly frc^h water grayling, Thymallus. SALMONID^E. 59 much in different specimens of the same species that it would be very unsafe to base any specific differences upon such a slender substrata of fact. 7. The form of the caudal fin in specimens of a given size, age, and sexual development. Here again the locality which the fish inhabited must be taken into consideration, for it has a great bearing upon the formation of the fins, being required of a much greater strength in rapid streams than in such as are sluggish. Age is no criterion as to size : and sexual development depends upon some, at present, unknown factor, for it seems that temporary sterility is not absent among the salmon. 8. A great development of the pectoral fins when constant in individuals from the same locality. Here sex has an undoubted influence on the size of this fin, it being frequently most developed in the males. Variations in the size of fins do not show sufficient differences on which to constitute species, while in the shape, more especially of the caudal, we find them frequently varying with age, being more or less emarginate in the young compared to what it becomes in the semi -adult and adult stages. 9. The size of the scales. Here the number of rows existing in a line from the back of the adipose dorsal fin to the lateral-line certainly affords one of the most constant characters, but the number along the lateral-line is much more deceptive. Having enumerated the characters stated to be most constant among the two first sub-generic groups in the genus Sahno, I arrive at the conclusion that most of them are fallacious, and that too great a stress having been placed upon them, many errors have resulted. The consequence has been that the number of species has been unduly augmented, and local races having been accorded generic rank, intermediate forms have not been searched for, but new ones constantly hunted up. Thus the synonymy will be a cause of endless confusion to future ichthyologists. Besides this every little variety of form, colour or structure, has been accounted for by terming such hybrids. The proportions of different parts of the body vary with age among the Salmonidce as they do in other fishes, and even more considerably in some anadromous forms which have been subjected to unnatural retention in fresh waters, insufficiency of food or sickness from any cause. While the head of the male is usually longer than that of the female, although in barren males the disproportion is not very considerable. A few remarks are here necessary upon hybridism among the Salmonidw, for from our earliest authors on ichthyology down to the present period the existence of such has been remarked upon, and of late years artificial propagation has clearly proved that such may occur. Experiments in order to test this question were instituted by Professor Rasch in 1867, and he found that the ova of the sea and river trout are developed regularly, whatever forms were the parent ones, and that the offspring were fertile. That of the ova of the charr fertilized by the milt of the trout, thirty to forty per cent, were developed, but that many young fish perished after being hatched. Trout ova, fertilized by the milt of the charr, only gave ten per cent, of young, many of which were misshapen. Salmon ova fertilized with trout milt yielded forty per cent, of young fish, but more if the milt of the charr were employed. The ova of a hybrid between a trout and a charr could not be fertilized by means of a trout milt. The foregoing facts are suggestive that a very close relationship exists between the anadromous marine trout and the non-migratory form inhabiting fresh waters. Thus we are informed that the anadromous sewin, or anadromous trout of Welsh rivers, very commonly interbreeds with the brook trout, hybrids being the result. In the British Museum may be seen a beautiful series of these fishes presented by the Rev. A. Morgan from the Rbymney, a few of which have been retained in fresh water after the normal period for their descent to the sea had arrived. Some have elongated bodies, others comparatively long pectoral fins ; and, again, hybrids are said to be present between the sewin and the brook trout, a conclusion seemingly arrived at because their teeth are more developed than in the sea-going form, while their pectoral fins and colour approximate to those of the non-migratory 60 PHYSOSTOMI. brook trout. Sterility, however, does not appear to normally exist in these so-called hybrids which raises a suspicion that we may be dealing with developing varieties and not with hybrids at all. And as these forms have facilities for returning to the sea, did they desire to do so, we are led to ask whether some of them may not be changing their conditions of life, and as a result developing structural differences, or even whether they and the brook trout can be really distinct species.* At Sir James Gibson Maitland's fish farm at Howietoun, some of the young of the Loch Leven trout take on cannibal propensities, and if small their colour is yellow, their teeth become abnormally developed, and they grow very rapidly. It is thus evident that under certain circumstances we may find trout provided with stronger teeth than is usual in the species. If we look at examples of sewin retained some time in fresh water ponds we see their pectoral fins more pointed and usually longer than in their sea-going relatives. This leaves chiefly for consideration whether these silvery forms with black X-shaped spots could, under any conditions, assume the deep coloured and spotted appearance of the common brook trout, or anything approaching to it. At Howietoun this general yellow tint shows itself when the fish has arrived at about its fourth year, but is also affected by seasons and food. When fed upon horseflesh they remain of a gray colour, if clams (Pecte?i ohtusata) are given they assume the yellow colour. Overcrowding large ones, or such as are 4 lb. or upwards, induces rusty spots ; if the numbers are reduced, and vegetable food given, as lilies and clover, they became gray ; while silvery scales are a sign that they are in their primest condition. The young parrs may retain red spots up to eighteen months old, but such are almost absent between that age and three years. Red spots on large fish are mostly perceived in examples intermediate between kelts and trout in their primest condition, but occasionally they are present all the year round. During the breeding season the males, if healthy, assume a brownish orange colour, or if from considerable depths a darker tint, while the females are golden or orange red. It consequently appears that conditions of health and changes of food may occasion alterations not only in the superficial colour of these trout, but likewise in their more deeply-seated colour spots. The foregoing point out that as the colour of Loch Leven trout may be altered by food and conditions of health, there exists no reason why the same changes may not occur among examples of sewin which take on a fresh water state of existence, more especially as the British Museum possesses some of these so-called hybrids from the Copenhagen Museum. In the series of Welsh fishes the whole of the changes from the anadromous sewin may be explained as natural sequences to ascertained causes and without accepting the theory of their being non-sterile hybrids. Much discussion has arisen why some of the salmon breed earlier in certain rivers than in others, whether this is due to the temperature of the water, or occasioned by alterations in the physical conditions of the bed of the stream and its affluents ; or, lastly, to the local breed being an early or late one. This last question involves the consideration of whether necessity having compelled the change from what was an early breeding river into a late one, the descendants of the fish removed to suitable localities would still adhere to the late period of spawning of their immediate progenitors, or return to the earlier time of their ancestral stock. In looking at these questions it will be necessary first to consider whether any general rules as to dates of spawning among this family of fishes can be deduced from what occurs in different localities. The period in Great Britain among the salmon may be roughly estimated (excluding local exceptions and climatic eccentricities) at from the commencement of September until the middle of January. Sir Humphrey Davy, writing from Southern Austria, remarked that " the charr I got this moruing with mature eggs was just about to spawn, yet in England * If, as asserted, these are hybrids between two species, the sewin and the brook trout, it is difficult to understand why these is a regular gradation between the two forms. salmonim:. 6i they spawn in the winter. If summer is the spawning time of the charr and trout of the lakes of Southern Austria, it is connected with or owing to the waters at that time being of the temperature best fitted for the purpose, most of these lakes being fed by mountain streams, frozen in the winter, and full in summer from the melting of the snow." In Sweden, Artedi remarked that the salmon spawned in the middle of the summer. Dr. Heysham stated that in Cumberland salmon at first prefer spawning in the warmer streams, leaving the snow-fed ones until later on. Yarrell considered that " rivers issuing from large lakes afford early salmon, the waters having been purified by deposition in the lakes ; on the other hand, rivers swollen by melting snows in the spring months are later in their season of producing fish, and yield their supply when the lake rivers are beginning to fail." I think that without multiplying instances the fact may be fairly assumed that temperature has some influence in the locality selected by salmon for breeding purposes, the colder and more exposed streams being usually left until somewhat later than the warmer ones, while in very cold regions spawning may be deferred even until the summer months. Were the foregoing views correct, and if temperature irrespective of geographical location has a marked influence upon the time these fishes spawn, we ought to be able to observe such among the trout and Anaclromous Sahnonoids despatched in the form of ova to Tasmania from this country. Turning to Mr. Allport's account (Proc. Zool. Soc, 1870, p. 25) we find a most marked corroboration of these views. We know the cold season in that portion of the globe cori'esponds with our summer, and the very first brook trout which were spawned in Tasmania occurred on July 3, 1866 ; by the 7th of August fourteen females had been stripped, and shortly afterwards five pair of trout were observed constructing redds in the River Plenty. During June, July and August, 1867, the trout were again stripped of their ova artificially. In this country, as observed by Buckland, trout spawn at different periods in different rivers from about September to February. The very first Tasmanian bred trout hatched from English trout eggs have not selected the month for spawning adopted by their ancestors in this hemisphere, but have chosen others which are better suited for their purpose, clearly demonstrating the possibility of trout being capable under changed conditions of varying the period of the breeding season. But because temperature exercises a manifest influence as to when and where the eggs of Salmonidce are deposited, it does not follow that it is the temperature of the water which is the sole cause the salmon has under consideration as to the period at which it shall enter certain rivers, some of which are known to possess spring fish, or such as ascend from March until June, whereas in others they more commonly pass up during and after September. I will first give an instance of a river which was originally an early one, but was found to become a late one by the Earl of Home, who, in 1837, observed " that in the Tweed a very great change has taken place within these twenty or thirty years ; a considerable portion of the breeding fish not arriving into breeding condition until long after the time they had formerly been in the habit of doing so." But here the question arises whether this had happened consequent upon any changes in the river, or alteration in the natural period of spawning in the fish irrespective of the condition of the waters. The river itself, it is observed, had changed due to the draining of the sheep farms on the hills, the effect produced being that a little summer flood which took a fortnight or three weeks to run off previous to 1795, is now completely run out in eight hours. The bogs on the hill sides, which were the feeders to the river, have the water at once carried off by drains, causing sudden but short floods, which have all run off before the river has had time to clear itself. Sir H. Davy compared the Tweed district as it was prior to these drains, to what it had become subsequent to their construction to two houses, the one covered with thatch, and the other with slate ; the first dripping for hours after the rain has fallen, the other ceasing when the rain stops. If sufficient water for ascent does not exist, if no safe-holding pools are present, as observed by Mr. Brandon, a spring salmon would have but little chance of 02 PHYSOSTOMI. ascent, or if it did the groat probabilities are that as the water became low it would be knocked on the head. And though he supposes these early fish breed similar descendants, we have but little proof of it, although many excellent fishermen hold the same view. In some Irish rivers the breed of early fish was almost extinguished by allowing the nets to capture all for a season or two, when it very soon came to the point that there was nothing to capture. Kelts and what to do with them has exercised many minds, and I cannot resist thinking that, doubtless, unintentionally, the opinion of some of our older authors have been either misunderstood or misquoted. Without more than just touching upon this subject it seems that it may be divided as follows : That the salmon subsequent to the spawning season becomes sickly, and is as well destroyed as kept ; that while mending it consumes more young salmon, trout, and other fish than it is worth ; that kelts might be eaten. After spawning salmon becomes much exhausted and very easily susceptible to disease and capture. It has been proposed to kill all the male kelts from the commencement of February; and all of either sex from the commencement of March. That the act of fertilizing ova is not invariably fatal to the salmon appears easy of proof, for the male parr possesses milt capable of fecundating ova. It is, therefore, evident that such must be evacuated or retained, and if the latter disease would be induced. Trout kept in confinement may be spawned more than once, omitting the consideration of whether such only takes place on alternate years. A correspondent of the Field observed, " a few years ago a fine male fish of about 20 lb. was used for spawning purposes at Stormontfield ; a mark was put on him by means of a copper wire, and two years afterwards he was got when nearly 30 lb. weight on the same ford and at the same season ; and, after doing duty again was returned to the river, hale and strong, but was not traced afterwards." Mr. Brown records how, on May 4, 1861, he hooked a kelt weighing 161b., and having fastened round his tail a copper medal, on which was stamped " Athol, No. 78." It had been caught on the preceding April 1, when it only weighed 13^ lb., thus showing an increase of 2h lb. in five weeks. The results of the Duke of Athol's experiments are too well known to need recapitulating. Dr. Gunther suggests that old males or those possessing a hook to the mandible, perish after the efforts of propagation, and cites the observations of Stella, Pallas, and Richardson on the salmonoids of Kamtschatka and North- Western America. He observes of kelted salmon : " Probably those which reach the sea alive perish there." Sir John Richardson, however, remarked : " The destruction by poachers in the higher parts of the rivers of the large enfeebled kelts, or fish which have completed their spawning operations, is also extremely prejudicial, for these individuals (almost utterly useless as food at the time alluded to) would, if allowed to descend to the salubrious sea, ere long revisit their native streams, greatly increased in size, and full of health and vigour." During the period a kelt is mending it lives mostly on small fish, especially young salmon and trout ; and Mr. Francis Francis suggests whether, this being the case, it is worth its keep. That by destroying so many small fish, the kelt, it is true, may return of a larger size, but it is questionable whether the river regains so great an aggregate weight of salmon as if numbers of the kelts were slaughtered. It has likewise been proposed that people should be permitted to kill and eat these kelts, which otherwise probably become lost as food. But prior to such a proceeding being sanctioned, it might not be amiss to inquire whether they would be wholesome. Certainly a correspondent of the Field remarks : " I was going to Ilfracombe lately, and saw many old back fish being hawked about. These old salmon come back to the tidal waters to recover before going to sea, and are caught by the score, and have been sold for fourpence a pound." But if eaten they may occasion poisonous symptoms. Thus Buckland relates how a water- bailiff, who was a strong, healthy man, ate a portion of one, and was made so ill that he was confined to his bed for two days. Dr. Gerald Boate, writing from Ireland in 1645, tells us leprosy was caused " through the foul gluttony of the SALM0NIM3. 63 inhabitants in the unwholesome devouring of foul salmon when they are out of season, which is after they have cast their spawn, upon which they do not only grow very weak and flabby, but so unwholesome as it would loathe any man to see them." Not many months since I saw some unseasonable salmon in the possession of a fisherman, and inquired what he intended to do with them. He informed me they were useless in the market, because if cooked their flesh would become more or less black ; but, with a grin, continued, that they did excellently well kippered ! A.

The true salmons which are included in this division of the genus Salmo consist of fishes which normally reside in the sea (although in some latitudes they live in lakes), and migrate to rivers in which their ova are deposited and the young hatched and reared. Here we have true anadromous forms, and as the salmon or salmon-trout have the same peculiarity in selecting suitable localities for breeding, differentiated by the fish ascending to nearer the sources of rivers, I propose giving a brief outline of how reproduction is carried on. Salmon enter our rivers in varying numbers throughout the year, unless impurities (as in the Thames) have annihilated the breed. At certain times, as during the cold season, they ascend for the purpose of reaching their spawning beds, and having deposited their eggs in redds or nests, they descend to the sea in a miserable condition, many of the males succumbing from exhaustion. Rondeletius and also Gesner, who wrote upon the salmon upwards of three and a quarter centuries ago, were both upholders of the doctrine that salmon spawned in the sea, one which, were it believed in and acted upon, would be disastrous to our salmon fishei'ies, as it might be advanced that these fishes could as well breed in the ocean as in rivers, consequently on their behalf no necessity arises for keeping our fresh waters pure, or having free passes in our streams in order to allow them to reach their spawning-beds. It was probably from such views sprang the notion of the parr being a distinct species, and even now there are some who doubt whether our " last springs " are the young of Salmo salar. Willughby, in his History of Fishes, published in 1686, lib. iv, adduces his reasons for disputing the correctness of Rondeletius's and Gesner's opinions; while Pontoppidan, in 1755, in his Natural History of Norway, returned to Gesner's views, asserting that he was well assured that salmon chiefly eject their roe at the mouths of rivers, where they empty themselves into the sea, or else a little above the salt water. Mr. Brander (Field) remarked upon having observed during the preceding summer some holes scooped out in the gravel close to the mouth of the small river Lopie (near the Spey), and within the reach of the salt water, and here he found in January, 1882, a few salmon working at their redds, which were within a mile and a half of the sea, and covered once a fortnight at spring tides with quite salt and undrinkable water, for perhaps an hour's time. Sir James Matheson, in Davy's Philosophical Researches (p. 261), has recorded at the mouth of the Greamster, in the Island of Lewis, a similar instance, continuing that the spot is covered with 64 PHTSOSTOMI. " brackish water " only for about two hours at each high tide, but not at all during 1 the neaps, while this brackish water is so diluted as to differ but little from fresh water in specific gravity, the tide serving as a dam to the river water, and by obstructing its free outflow, causing its accumulation and overflow. The foregoing instances occurred near the mouths of small rivers, and should their state be such due to pollutions or insufficiency of water that Salmon-idce are unable to ascend, they may drop or deposit their ova in the sea or at the mouths of rivers ; but suppose it is thus deposited, experiments have proved that the presence of salt water is fatal to the fertilizing property of the milt, as also to the life of the impregnated egg, should it come in contact with it. Sir J. Matheson, during the winter of 1860-61, had the following experiment made upon two batches of fertile salmon ova. One lot was placed on a wire cloth in a glass vase, wherein was brackish water which was daily changed, but they all died at the end of the tenth day. The remainder were similarly treated, but with fresh water, and in due time they all arrived at maturity. Mr. Sinclair (Field, February 4th, 1882) remarks upon having taken about one hundred eyed ova, of which two portions were enclosed in wicker baskets and buried in separate streams, one of which was reached every tide by salt water, whereas the other was entirely fresh. They were examined in about three weeks after one set of spring tides, when all which had been reached by the salt water were found to be dead : not so those in which the stream was entirely fresh water. The remaining third were batched in a wash-hand basin, in which was fresh water changed once a day. Dr. Davy also instituted somewhat similar experiments with artificial saline water, from which it appeared that a degree of saltness, almost or quite equal to that of sea water, is pretty speedily fatal both to the ovum of the salmon and to the young fish : that the same effect is produced on the young fish by brackish water of specific gravity 1016, but in a longer time, and that, when the solution is so diluted as to be reduced to the specific gravity 1007, the advanced ovum may be hatched in it, and the life of the young fish may be sustained in it for a few days, but with diminished powers. The eggs of the salmon are small, round, elastic bodies, of a clear white, pink, or even coral colour. Due to their tough outer coat they are very elastic, as may be seen by throwing one on the ground, from whence it will rebound like an india- rubber ball. This strength and elasticity we know must be an exceedingly important property if we remember where these eggs are deposited and what an amount of pressure they may have to undergo. Young salmon are hatched from eggs deposited in rivers, not near to its mouth, where the tide or the current would be too strong for the young fish to live in, but in small and often mountainous streams, where the water is pure and shallow, having a gravelly bed which permits the redd or nest to be constructed, while deep pools in the vicinity allow the breeding fishes to retire into them for rest. The salmon ascends our rivers to a suitable spot, and in the gravel at the bottom of the stream constructs its redd, which work would seem to be the occupation of the female. She lies on one side, and, by moving her tail rapidly from one side to the over, fans up the gravel until she gradually sinks into a kind of trough, the male remaining near, ready to give battle to any intruder. For this purpose his lower jaw is furnished at this period with an offensive weapon in the shape of a cartilaginous, hook-like process. The female (waited upon by the male) now deposits her eggs in the trough she had made, and these are fertilized by the male, and subsequently covered with gravel to some feet in depth, the whole forming a redd. She now falls back into one of the deep pools, until she has acquired sufficient strength to again shed more eggs. During this period the salmon (similar to the shad and many other fishes) is indisposed to feed, and lives on the stock of fat it has laid up while resident in the sea. It has been computed that every female salmon deposits about nine hundred eggs to each pound of its weight, and that only nine hundred of these in every 17,000 shed in British rivers ever attain the parr stage. As might be anticipated, eggs deposited in a running stream are very liable to be carried away by the current, and the places selected by salmon for SALMONID^E. 05 their redds are often the localities where trout have previously deposited their eggs, which now become routed up and carried away down stream to be devoured by every hungry fish. The time that salmon eggs may take before they are hatched is subject to variations as great as from 35 to 148 days, which last period occurred at the Crystal Palace in experiments instituted there, and 144 in the Wenham Lake ice vaults. While acting upon previous experience, Mr. Youl succeeded in transmitting salmon eggs to the Antipodes in small boxes packed in ice, and which retarded hatching until the 145th day. Mr. Branden examined a redd that appeared to have been left dry, but on opening it found that a little water was trickling through the stones and gravel, which was sufficient to keep the ova healthy. Having scraped a hole, he obtained a considerable number of eggs, and these he transferred to a pail of water, where two-thirds hatched within periods varying from five minutes to twenty-four hours. About a week subsequently he returned to the same spot, and had another dig for salmon eggs (no rise having occurred in the river during the interval). He collected more, and putting them into the water, they hatched as the former ones had done. He very fairly advances that this may be a provision to prevent ova deposited in localities where the depth of the stream is liable to considerable fluctuations, from becoming lost or killed, as must occur unless a delay, to obtain a suitable time, could be provided for. For as the floods come and sweep up these redds, the imprisoned ova are let loose, at a time when they are ready to burst and the young to emerge. In fact, like the chrysalis, the eggs may be able to abide a suitable time. But salmon eggs, even in redds, are not permitted to rest in peace and hatch in security : they have many accidents to escape from and numerous enemies whose vigilance must be avoided. Not only may floods prematurely sweep away redds with their unripe eggs, but during the continuance of such, spawning fish are unable to avail themselves of their usual breeding grounds because they are too deep in the water. They consequently may have to shed their eggs in the stream, when they will become lost, or covered with mud, or else push higher up to where there will be more chance of their redds being left dry, and the ova perishing; even in their annual spawning grounds, where their eggs may have been deposited, severe seasons of drought may occasion most disastrous results. Irrespective of the seasons, the eggs have numerous water enemies, as the fresh water shrimp, which hunts out the nest, when they are merciless to the eggs, the larva of the may-fly and of the dragon-fly and even some birds as the dabchick. While swans and ducks enjoy nothing so much as the spawn of fishes, in which taste the vole or water-rat appears to coincide. Due to the many destructive agencies at work an ingenious plan of artificial hatching and rearing has been adopted with great success, while by regulating the water, droughts and floods are prevented, and many enemies are excluded which run riot among fish eggs left in a state of nature in our rivers. Supposing some young fish have come forth, it does not follow that the little ones are strong and healthy. The temperature of the water ought to range out of doors about 42 or 46, nor permitted to sink below 35, while if it reaches freezing point, such will most probably be fatal. Should it rise to 50 the eggs may become prematurely hatched : the higher the temperature the sooner the young appear, and the more weakly they may be expected to be. Sometimes the jaws are deformed in the fry, or the spinal column is curved, even two fish may be connected together, like the Siamese twins : likewise two or even three heads have been seen fixed to one body. When these little fish emerge from the eggs they have a large bag (the umbilical vesicle) attached to their stomachs : this contains the nourishment which is to serve them for several (three to eight) weeks' subsistence, and they do not commonly take in any food by the mouth until it is absorbed. Weighed down by it they lie quietly among the stones at the bottom of the stream and seek concealment from fish larger than themselves, water insects, and other enemies which now commence to feed on them. The salmon is rare in our rivers in comparison with the number of fry n 5 66 PHYSOSTOMI. hatched, and which would be quite sufficient to form a good supply had they a chance in the battle for life in the lower waters. The paucity of these fish is due (excluding poaching) to three main causes : (1) Difficulty in the ascent of breeding fish owing to natural or artificial obstructions in the river; (2) immoderate netting ; and (3) pollution of the water. It is commonly observed that the interests of the proprietors of salmon fisheries are not identical throughout the entire extent of the stream, occasioning a clashing of views which are inimical to the fisheries, and consequently to the general public. The proprietors of fisheries living in the higher waters of our rivers argue that pollutions are permitted unchecked access in the lower reaches, that immoderate netting is almost continuously carried on, giving the fish, except in the close time, but little chance of escape. Thus the upper proprietors see but few fish, excepting during the breeding season, when it is illegal to capture them. They are in a manner " clucking hens," whose duties seem to be to take care the eggs are hatched, rear the fry, and speed the parting guest as it descends to the sea, from whence nets and other obstructions and pollutions in the lower portions of the river will most probably prevent their ever re-ascending ; or else merely in sufficient numbers to maintain a sufficient supply for the lower waters. Official statistics are misleading, as they ought to show the yearly quantity of salmon taken in each portion of every river, not the number of boxes of salmon received at Billingsgate. It cannot be a source of surprise if the breeding grounds are not strictly preserved : for the rearing of salmon is asserted to be done at the expense of the local fish, which are residents of the upper waters.

The proportions of one part, of the body to the remainder vary consider- ably in this fish, thus in the young we find a comparatively large head and eyes, a short snout and rounded body, &c, : but as the adult stage is attained there is greater depth of the body due to a more prominent abdomen. After bi'eeding, the kelts are recognizable by low, lanky bodies and long heads. The length of the head varies with age and sex, being comparatively slightly longer in the parr than in the female grilse or salmon, while in the male salmon it is longer than in the female. Length of head from 4j to 4| or even 5 in the parr and male salmon to 5 or 5i in the female salmon and grilse, while in barren males it is similar to what is seen in females, of caudal fin from 6 in the parr to 7\ in the salmon, height of body, which is greatest beneath the origin of the dorsal fin, 4 to 5 in the total length. Eye situated slightly in front of the middle of the length of the head (or in the middle of that length in breeding males) and comparatively much smaller in adult than in young fish : interorbital space convex and equal to about 2/3 the length of the postorbital portion of the head. Snout much pro- duced in the male, and during the breeding season the extremity of the lower jaw is provided with a strongly curved prominence which precludes the closure of the two jaws. The posterior extremity of the maxilla reaches to beneath the middle of the eye in the parr but beyond its posterior extremity in the adult : while it is comparatively wider in the young than in the adult. Opercle higher than wide, from about 1/5 more in the parr, or 1/4 in the grilse or young salmon, and 1/2 in large salmon : subopercle from 1/2 to 1/3 of the height of the opercle, while its posterior margin forms a semi-circular curve along with that of the opercle.* Preopercle with its angle rounded and having a rather distinct lower limb.

SALMONID^E. 95 Breeding. Similar to the brook-trout, at Loch Leven they ascend the streams for tin's purpose towards the end of September or commencement of October. Sir J. Gibson-Maitland crossed the ova of the Loch Leven trout with the milt of the sea-trout in the winter of 1881, and 95 per cent, were hatched. It appears to me that the progeny will not be hybrids, but merely two varieties of one form breeding together with the result of non-migratory Loch Leven trout having perhaps more migratory instincts. Before passing on to the next species, I cannot resist remarking upon the magnificent fish-breeding establishment at Howietown, raised by the energetic skill and capital of Sir J. Gibson-Maitland. Here, although charr and brook- trout are reared, it is the Loch Leven trout that is more especially cared for. The hatching-houses are capable of hatching and raising 12,000,000 eggs and young fry up to the period when they can feed themselves, when they are transferred to the rearing-ponds, which are in a regular series, so that each year's produce is kept by itself. To show what good management and judicious skill may effect, I Avould instance the pond for the six-year old fish, 80 yards by 40 yards, with a stream passing through it : here, when I visited this interesting establishment, were 1200 Loch Leven trout from 4 to 7 lb. weight each, and all in excellent con- dition, conclusively demonstrating how watery wastes can be turned into excellent food-producing reservoirs. If the experiment proves a financial success, as appears highly probable, its owner hopes to see similar institutions elsewhere, which would be the means of extending to an almost unlimited extent the fish-producing properties of the country now so lamentably wasted, from the apathy of the owners, the greed of the fishermen and the want of energy and knowledge in our legislators. Diseases. These fishes are affected with disease similarly to the salmon and the trout, while bay-salt has been used with success at Howietown in order to arrest a fungus which has from time to time appeared in the ponds. I was informed that crows after having eaten diseased fish moulted and became most miserable objects and three or four were thought to have become leprous. As food. The Loch Leven trout is generally very highly esteemed, not only for the red colour of its flesh, but because it possesses a peculiar delicacy of flavour. Habitat. This non-migratory fresh water trout is found in Loch Leven in Fifeshire, and other lochs in the south of Scotland and the north of England ; while due to the success of the artificial fish-breeding at Howietown the variety is being extended all over the kingdom to as far south as Hampshire. Whether in a few years all trace of them will have been lost, and they will assume the colour and proportions of the brook-trout, only time can demonstrate. In the English edition of Limueus incorporated into the Encyclopedia Londinensis, p. 53, it is observed, " that it is not above fifty years ago that Mr. Copland conveyed perch into the Ken-loch and the River Urr, where tbey have thriven remarkably well : as has been the case with the trout taken from the River Leven and deposited into Loch Long in the county of Renfrew." While Parnell recorded having met with this form so far north as Sutherlandshire. As to the size this fish attains, six-year-old examples, some weighing as much as 7 lb., were found at the Howietown ponds in 1882. In Loch Leven on April 27th, one 10 lb. weight was netted ; while in the New Statistical Account of Scotland mention is made of two examples captured previous to that date, one being nearly 9 lb., the other almost 18 lb. The example figured is 12 inches in length, and one of a pair sent me from Loch Leven by the late Mr. Alston. 2 B. Salmo fario, Plates CIX, fig. 3, and CXIII, CXIV, and CXVI, fig. 1.

" Mr. Low says, in the Loch of Stenness, Orkneys, is found the gray trout : also a trout of 36 lb. weight or more, along with the common trout, occurs both there and in Zetland." This large form Richardson considered to be Salmo ferox, and Gunther a new species which he termed S. orcadensis. This loch is the largest in the Orkneys, about 9 miles long and 1| broad, fresh in the upper portion, brackish or even salt in the lower. Dr. Gunther defines this fish as " a non- migratory trout," very similar to S. nigripinnis, but distinguished from it by a broader and stronger maxillary, larger scales on the tail and a greater number (50) of pyloric appendages, instead of from 36 to 42, while S. ferox has at least 49. The teeth along the body of the vomer form a single or double row which are more or less persistent. Richardson was evidently correct in associating it with S. ferox possessing saline proclivities.

This seems to be a trout which has taken on cannibal propensities (see page 94) and its food appears to bo almost exclusively fish. It attains a large size, while Richardson alluded to a variety occurring in Loch Lojal, in Sutherland, of a purplish brown above, blackish gray beneath, and the entire body covered with dark sepia-coloured spots, smallest below the lateral-line. It is known as .lliiildagh or " big fat fellow " in Lough Neagh and some parts of Ireland (Harris, Hist. Co. Down, 1744, p. 236), and is said to be a deep water form confined to lakes, seldom wandering to rivers or to the sea, mostly taken by trolling, though sometimes with a fly. It has been known to return a second or third time to the bait even after it has been dragged 40 or 50 yards. It ascends a short distance up rivers to spawn : Thompson found one from 10 to 12 lb. weight contained 4620 ova. Its flesh is of a dull orange colour and generally coarse. It has been found in the lochs of the north of Scotland and as far south as Ulswater and Derwentwater : also Llanberris in Wales, and in many Irish lakes as Lough Neagh, L. Melvin, L. Eske, L. Erne, and most of the larger ones. Among our earlier British ichthyologists we find that Berkenhout termed the SALM0NIDJ3. 97 " great lake-trout " 8. lacustris (under which name it appears in Sampson's Londonderry and Dubourdieu's Co. Down), supposing it to be identical with the continental variety ; but of late years differences have been asserted to exist between the British and foreign race. Jardine and Selby termed ours S. ferox, the specific name having been chosen to characterize its size and ferocious habits. Jurine believed in the specific identity of all the forms of trout in the Lake of Geneva; and it would be but reasonable to expect that if the British 8. fario under favourable conditions could attain the size of 8. ferox, the continental 8. fario, which is the same species, would, under like conditions, also arrive at being a great lake-trout. Moreau (vol. iii, p. 534) places among the synonyms of Trutta (or Salmo) fario, " La Forelle du Lac Leman, Fario Lemanus ;" and at p. 536 observes, " La Truite feroce, Trutta ferox, Valenc, des eaux du Foretz est une simple variete de la Truite vulgaire, et nullement une espece particulierc." Although these authors have, in my opinion, been perfectly correct, still there existed the statement of Dr. Giinther that structural differences existed among the specimens in the British Museum, showing that S. ferox possessed 56 to 57 vertebra? and 43 to 49 caeca, while 8. fario had 57 to 60 vertebrae and 33 to 47 caeca. I have, however, now shown (page 56) that examples of S. fario may have from 56 to 60 vertebrae, and likewise from 33 to 54 caeca ; thas overlapping the entire amount of variations ascribed to British forms. Sir William Jardine stated that " the dorsal fin in 8. ferox contains 15 rays, and appears to be constant in that number;" and that " in form it is generally shorter proportionally and deeper than in large specimens of 8. fario." Sir J. Richardson distinguished between the great lake-trout and brook-trout by the size attained. The tail " in adults is perfectly square, or might even be described as slightly rounded at its extremity ; in the young it is slightly forked, and appears to fill up gradually as the fish advances in age." The relative position of the fins and the number of rays in the dorsal, were said to vary from 2-4/11 or a total of from 13 to 15. Thompson observes that he found from 33 to 49 caeca in various examples of 8. ferox from 12 to 17 inches in length. I possess undoubted examples of the common brook-trout having from 13 to 15 dorsal rays : Moreau likewise in French specimens of the brook-trout found 3 or 4 undivided and 9 to 11 divided rays in the dorsal fin : likewise 3 undivided and 7 to 9 divided anal rays : while as to the caudal fin being square in adults, so it also is in large examples of the brook-trout. Yarrell (ed. 3, i, p. 281) gives an illustration of a large Thames trout (a locality not frequented by 8. ferox according to authors), in which the caudal fin is as rounded as in any examples of great lake- trout of similar size. It was a male, 28 inches long, having a hooked lower jaw, while it weighed 11 lb. The comparative length of the head and height of the body are almost identical with what obtains in an example of 8. ferox, 20 inches long, from Llanberris, and which is in the British Museum. I examined a few years since a specimen (which is still preserved) of trout, weighing upwards of 131b., taken from a large sheet of water at Alresford in Hampshire, which is well stocked with coarse fish. This was one of about a dozen that some years previously had been transferred from the contiguous stream, to which they could not subsequently obtain access. Without a history of from whence the fish came, I maintain that no ichthyologist could be certain whether any given specimen is or is not a " great lake-trout." " The trout," says Dr. J. Davy, " when it feeds principally upon fish must be extremely active and strong ; and consequently, from its predatory mobile habits, acquires large teeth, large fleshy fins, thick skin, and great pectoral fins for turning."

Variety d. Salmo nigripinnis, Plate CXV, fig. 2. Salmo nigripinnis, Giinther, Catal. vi, p. 96 ; Houghton, British Freshwater Fishes, p. 120, c. fig. I now propose alluding to Salmo nigripinnis, Giinther, which is similar to S. Cornubiensis as described by Borlase, Artedi, etc., and which for many reasons may be considered as a variety which in suitable localities frequently developes into S. ferox. I have been most liberally supplied with specimens from Cardiganshire, through the kindness of Sir Pryse Pryse ; and among them is one form which was alluded to by Barrington, in the Transactions of the Royal Society for 1774, as the " Hog- backed Trout of Plinlimmon " (Plate CXI, fig. 1), which Dr. Giinther, as I believe correctly, considered identical with his S. nigripinnis. My example, which is about 11 inches in length, is peculiarly interesting, as forming a link between S. nigripinnis and 8. ferox, pertaining partly to one form and partly to the other. The following are the differences noted in the British Museum Catalogue : Salmo nigripinnis. Salmo ferox. D. 14, A. 12, P. 13, Csec. 36-42; D. 14, A. 10-11,* P. 16, Crec. 44-49; Vert. 57-59. Vert. 58-59. Head small. Snout not much pro- Head of moderate size. Snout duced in males. No mandibular hook much produced in males. Mandibular observed. Head of vomer with a trans- hook when spawning. Head of vomer verse band of teeth, on body generally small, toothless ; body with a double or in a single series. Female mature at zigzag line of teeth. Caudal truncated 7 inches. Largest example observed, at 18 inches; in larger examples 16 inches. rounded. Female mature at 14 inches. Largest example observed, 31 inches. These reputed two species have been found residing in nearly or quite the same localities in England, Scotland, Wales, and Ireland. The size of the speci- mens examined is important, as tending to modify the conformation of the opercular pieces, as well as of the fins, the character of the scaling, the propor- tionate diameter of the eye, and the existence or the reverse of the teeth on the front of the body of the vomer. The teeth being present on the anterior part of the body of the vomer in the smaller S. nigripinnis, but absent from the same place in the larger ones, S. ferox, is symptomatic of endentulation due to age. The same argument applies to the mandibular hook, it being well known that among the Salmonidse this production is absent in young males, as may be readily observed in the parr which possess milt ready for shedding. The number of pectoral rays is immaterial, as I find, even in the British Museum specimens, examples of S. nigripinnis, S. ferox, and S.fario possessing from 13 to 15. The foregoing leaves the following as Dr. Giinther's primary reasons for dividing these two so-called species : S. nigripinnis has D. 14, A. 12 ; head of the vomer-toothed, and generally a single row along the body of that bone ; caudal fin with pointed lobes. S. ferox : D. 13, A. 10-11 ;* no teeth on the head of the vomer, but a double row along the body of the bone ; caudal fin truncated. The example of the " hog-backed trout " in my collection has D. 14, teeth on the front portion of the body of the vomer, and a distinct lower limb to the preopercle, thus belonging to S. nigripinnis. Likewise A. 11, a double line of teeth along the body of the vomer, and the caudal fin almost square at its extremity or becoming similar to what is given as diagnostic of S. ferox. I have likewise six smaller examples of S. nigripinnis in which teeth are present on the front portion of the body of the vomer and in a zigzag line along the body of that bone ; the caudal fin in the smallest has pointed lobes, which have become rounded in larger specimens ; the ccecal appendages varied from 35 to 44. In some of these fish the posterior margin of the preopercle was * Thompson (iv, p. 157) found D. 13-14, A. 11-12. SALMONIBvE. 99 rounded, and had no distinct lower limb. The maxilla was much feebler than seen in some other local races of brook-trout, which was remarkably the case on comparing it with a beautiful Yorkshire variety sent me by Mr. G. Brooks, f.l.s. ; but even among the Yorkshire specimens I found great differences to exist. These Cardiganshire fish in the Tivy are found to 4 lb. or 5 lb. weight, but rarely if ever take a fly when so large, bat are to be caught by means of a minnow. Small ones removed to a pond attain in about 3 years to 31b. or 3^- lb. in size, their flesh is pinkish, and their flavour said to be excellent. Out of 8 examples, 6 had no red spots, one had them along the lateral-line : and the last had them both on the lateral-line and in one or two rows below it.* If a trout, normally belonging to a small race, as S. Comubiensis, is transferred to a lake or reservoir, as in the one near Penzance, where food is plentiful, it attains a size to which it never reaches in its ancestral stream, showing capacity for growth to be inherent, and called into action by luxuriant living. In Scotland the largest examples are in lochs ; so also in Wales and Ireland, although occasionally a large one may be found in a sluggish stream, especially if such passes over a rich soil. Should food be plentiful, a brook-trout may attain to many pounds in weight in suitable localities in fact to as large a size as the great lake-trout, which I hold to be merely a form of S. fario which indulges in luxurious living, or cannibal propensities. Variety e. Salmo estuarius, Plate CIX, fig. 3. Sahno estuarius, Knox, Zoologist, 1855, xiii, p. 4662. Salmo gallivensis, Giinther, Catal. vi, p. 88; Houghton, Brit. Freshwater Fishes, p. 105, c. fig. The most characteristic peculiarity of this form is said to be found in the small size of the coecal appendages : also that it is at once recognized from Salmo trutta by the excessive shortness of the tabes on the lateral-line. Four examples were recorded and four more passing into the brook-trout, termed hybrids. It is similarly coloured to freshwater forms. Knox's example had sixty vertebras, similar to the number present in the British Museum specimen, and the name he gave well denotes the chief characteristic of this variety. The example figured is 19 inches long, and came from Waterford. Mr. J. Har vie- Brown took in June, 1882, from a sea-pool or fish-pool at the mouth of the river, freshwater at low tide, salt or brackish at high- water, brown-river trout, periodically visiting the brackish localities, and taking on a silvery sheen of scales, much as he found them in North Uist. They are said to lose condition about spawning time, then disappear but not to ascend streams to breed. Couch alludes to Knox's estuary trout and observes upon its being a fish which has gone to the sea, and that he had received examples migrating seawards in May towards the deep. Variety /.

This has been considered distinct, due to the abnormal thickness of the middle coat of its stomach, otherwise, observes Mr. Barrington, there are no exterior marks by which the species can be distinguished from the common trout. Pennant asserted that the increased thickness of the stomach proceeds from the superior quantity of shell-fish which it finds in the waters it inhabits, and which may call more frequently for the use of its comminuting powers than is requisite * I intend depositing all these forms, along with my British collection of fish, in the South Kensington Museum. 7 * 100 PHYSOSTOMI. in those of our trout. Thompson (1. c.) observes that the coats of other species of Salmones than S.farw (of which only the Gillaroo is set down as a variety) become muscular from the same cause. He alluded to having found it in 8. ferox. Sir J. Richardson observes : " We may here note the existence of a strongly-marked and peculiar variety, called the Gillaroo trout of Galway. It is remarkable for feeding on shell-fish, in consequence of which (it is supposed) the coats of the stomach acquire a great degree of thickness, from which peculiarity it is sometimes called the gizzard trout." * Sir H. Davy remarks that " the charr of the lakes of Southern Austria feeding similarly (to the Gillaroo trout) have a like thick stomach." It generally prefers a rocky bottom, and is said to breed in lakes in their shallower pails, and not to ascend rivers for this purpose. But it is found in the Shannon, Lough Corrib, Lough Mask, Lough Derg, Lough Melvin, &c. The colours of this variety may be due to the character of the food it indulges in, while in some localities its flavour is considered excellent, in others quite the reverse. In Lough Melvin it is somewhat hog-backed, fine in colour, and well flavoured : in Lough Derg, soft, colourless, and inferior. Its stomachs are occasionally served up in Ireland as gizzards. Thompson obtained from the stomach of one example, about 8 inches long, above 1000 shells of Limneus pereger, Valvata obtusata, and a few Cyclas cornea. Stoddart observes: this variety is found in a small tarn or loch, situated on a shoulder of Ben More, in Sutherlandshire, about three miles from Innisnadamph, named Mulach Corry.

This variety, which is comparatively rather broad, was given me by Mr. G. Brooks, F.L.S., who informs me that it is found in Oxnop Beck, Swaledale, Yorkshire. The example figured is a female 10 inches in length. There is a considerable difference in the form and proportions of the sevei-al examples.. Colours it is the most beautifully-tinted form that I have seen, being finely studded with black dots placed in a light circle, and likewise with numerous blue marks and red spots. Its. dorsal fin is finely spotted, but the white anterior edge, so constant in most freshwater forms, is indistinct or absent. Scales fifteen rows between the posterior edge of the base of the adipose dorsal in a line passing downwards and forwards to the lateral-line. Stomach thickened and similar to the variety termed Gillaroo, which form, Dr. Giinther observes, possesses forty-four cceca, consequently if a variation in the number of such are diagnostic of distinct species, this is a variety of the Gillaroo. Respecting its exact habitat, Mr. Brooks observes that the upper part of the beck runs over millstone grit, but as it leaves the moor it gets upon mountain limestone, and from this point, for a mile and a half, to the point where it joins the Swale, it is composed of numerous small falls, with intervening little dark pools in which the trout lie. The beck is overhung all the way (on the limestone) by trees, mostly alder, silver birch and hazel, but with a good sprinkling of elm, mountain ash, &c. The beck is closely overhung and is in a narrow ravine. Variety h. Crassapuill trout. B. xi-xiii, D. 12-13 ( 9 3 -i*o) | 0, P. 14, V. 10, A. 11 (), L. 1. 125, L. t. 27/32. Six examples of this exceedingly interesting variety were sent me by Mr. Harvie-Brown in June, 1882. They were taken in Sutherlandshire, at Loch Crassapuil, where they are looked upon as land-locked sea-trout. Their fin rays are similar to those of Sahno levenensis ; a transverse row of teeth is present across the anterior portion of the vomer, and a double row along its body. The preopercle has a distinct lower limb in some, indistinctin others, while the shape of the subopercle * Hunter's experiments with hard and soft food on gulls, showed thickening of the muscular wall of the stomach occurred due to increased use. SALMONID^B. 101 varies. Fins the pectoral is as long as the head excluding the snout, it is not quite so pointed as in the Loch Leven form, nor so rounded as in the common brook-trout, but intermediate between the two. Scales 125 rows along the lateral-line, 15 from the base of the adipose dorsal to the lateral-line, 25 froni the lateral- line to the base of the ventral tin. Coecal appendages 46 in the one examined. Length of head 4 | to 5 in the total length. Colours silvery, with the upper two thirds of the body and head closely covered with x-shaped or round black spots, and in two of the examples a few red spots but mostly confined to the lateral-line. The loch has a pure white sandy bottom, which probably accounts for their silvery colour. When fresh caught their backs are of a vivid green, varying to pale sea-green and dark olive, in accordance with the depth of the water in which they live. Dorsal fin covered with black spots. These fish have the silvery appearance of auadromous forms, and externally strongly resemble the Loch Leven variety, but the number of coecal appendages is different, being almost identical with that observed in a Loch Leven example raised at Howietown, and one step nearer x'emoved from its marine ancestry than is the true S. levenensis. Did this species run up rivers, doubtless they would take on the colours of the brook-trout, as they have its dentition. They attain to 3 lb. or 4 lb. weight. Mr. J. Harvie-Brown (Land and Water) observes that at a far inland locality in Sutherkindshire, brown trout, dark and spotted, were caught in 1877, and introduced to a chain of lochs in the same county, which have their sources in innumerable springs of clear water from granite and limestone mountains (principally the former, as the limestone, for the most part, is at a lower level). These fish became, in a single year, silvery and covered with minute bright scales like sea-trout, and grew to the size of 1 lb. weight in twelve months, from at most j of a lb. The food in the loch is shell-fish and tadpoles, and the bottom granite, gravel, and sand. Monstrosities. Hog-backed trout of Plinlimmon, Cambridge Quart. Mag. 1833, p. 391 ; Cobbold, Edinb.

Origin of adipose dorsal fin about midway between the anterior insertion of the base of the rayed dorsal and the posterior extremity of the upper caudal lobe. . Pectoral as long as the postorbital portion of the head, or even of the entire head excluding the snout, in some examples it is more pointed than it is in others. Ventral inserted beneath the middle or last third of the base of the dorsal fin.

Scales from 13 to 15 rows between the hind end of the adipose dorsal fin in a row passing downwards and towards the lateral-line. About 26 or 27 rows from the lateral-line to the base of the ventral fin. Coecal appendages these differ considerably, apparently being influenced to a great extent by the locality they inhabit and the food which they can obtain. Colours these vary as has already been observed (see page 57), not only with locality but also owing to changes of food. Those from Wales and along the S.W. coast are of a somewhat darker appearance than those from the Midland counties and towards the north, and have rather more black but less red spots. 102 PHYSOSTOMI. I have already (p. 57) alluded to the parr marks of the young being occasionally continued throughout life in small forms, evidently adding to the confusion respecting what is a parr. Varieties. Trout, as already remarked, are exceedingly liable to variation, due to several causes. Some of these abnormal productions would seem to be hereditary ; in others the same exciting cause continuing in action occasions results as in previous generations. Giraldus Cambrensis, lib. iii, c. x, the Archdeacon of Brecon, who attended Baldwin, Archbishop of Canterbury, in a progress through "Wales in 1188, tells us of eels, trout and perch existing in the lakes of Snowdon which only possessed the right eye, but being invariably blind with the left. The Fischau, near Mandorf in Germany, was reputed to contain blind trout (Fr. Ern. Bruckmanni Epist. Itin. xxxvi, Wolfenb. 1734, p. 10). A deformed race of trout is asserted to exist in a small loch in Invernesshire near Pitmain ; among them there appears to be an arrest of develop- ment in the upper jaw, giving their heads a slight resemblance to those of bulldogs, due to the projection of the lower jaw (Encyc. Brit. 7th ed., art. Ang.). Similar malformations are seen in the "ground trout " of Penyghent (Yorkshire Vertebrata) and many other places. In Loch Islay exists a race of tailless trout, Salmo Islayensis, Thomson (Traquair, Journ. Anat. Phy. vi, p. 411, pi. xix, and Thompson, Science Gossip, 1872, p. 85), which in some streams has been traced to be due to the action of deleterious matter in the water (see Angler's Note Book, 1880, p. 66). Mr. J. Harvie-Brown observed, about 1876, in the river Carron that a contraction of the rays of the tail fins of the trout commenced, due it was universally believed to continuous pollution of the water through the agency of paper mills. At Malham Tarn, in Yorkshire, 1240 feet above sea level, the trout are distinguished by a deficiency or malformation of the gill-covers in about one in every fifteen captured. As I have seen the same result from breeding in confined places, I believe such to be one at least of the causes, perhaps conjoined with gill-fever when young. On Plinlimmon, and in adjacent parts of Wales, are " hunch-backed " trout, having deformed vertebral columns as already alluded to. In some, at least, of these instances the young are reared where cascades are falling over heights into a series of pools, and it has seemed to me not unlikely that either the egg or the fry coming within the reach of such, might suffer injury, and consequent disease of the spine (so common in fishes) be set up. Barrington (Phil. Trans. 1767) remarking upon some examples crooked near the tail continues, " these trout are only caught in a small basin, eight or nine feet deep, which the river forms after a fall from the rocks." Perch were found to be similarly affected, the same cause acting apparently on both forms. There are likewise races in which some local cause has set up local action, as of the stomach alone. This variety, the Gillaroo (see page 99), due to the food it indulges in, has the muscular coat of its stomach thickened, which abnormal structure has been reproduced in succeeding generations. For it must not be assumed, because in certain examples we are unable to find Lirnnea and other shells, that the fish has never consumed any ; they may have been digested, or it may have varied its food, or the shells may have been temporarily unobtainable. In County Derry, in the river Glenlark in the Munterloney Mountains, "Mr. Sinclaire states that the water and stones are deeply tinged with a rust colour, of which the trout likewise partake. Their flesh is very bad and of a metallic flavour ; so bad are they that the country people will not eat them, and as they are not fished for, the river abounds in them " (Thompson, iv, 153). Lunel remarking upon the various specific names that had been given to the varieties of this species, asserted Salmo fario, 8. lemanus, S.rappii and 8. laciistris, of Lake Constance to belong to one form which he proposed terming S. variabilis. Steindachner (Ak. Wiss. Wien, lii, 1865, Nov. 30th) identified 8. detex, Heck, with 8. fario. Pavesi (Pesci nel Ticino) considered the lake and river-trout of the Canton to be merely varieties of one species. "Unquestionably," observes Stoddart (Angler's Companion, 1847, p. 3), "there exists no species of fish which, judging of it by the external marks, holds claim to so many varieties as the common freshwater-trout. In Scotland almost every lake, river, and SALMONID^E. 103 streamlet possesses a breed peculiar in outward appearance to itself." Lord Home (Yarrell's Fishes) observes of two streams, the Whitadder and its tributary the Blackadder, that the first flows along a very rocky and gravelly bed, while the latter rises in mosses, also goes through them in the first half of its course, but subsequently along a rich and highly cultivated district. The trout in the first are silvery in colour: while those from the Blackadder are dark with orange fins. The many varieties are dependent upon external causes and chiefly to the abundance or the reverse of food and the nature of the water they reside in, the soil over which it flows, and other causes already treated of (pp. 57, 58). That this conclusion is based upon proof may be demonstrated by the result of what has become of the progeny bred from the brook-trout eggs taken in Hampshire or Bucks, by Buckland or Francis, and transmitted in 1866 to Tasmania, some of which have become great lake-trout. Mr. Arthur (Trans. Ota-o Institute, July 9th, 1878) tells us that unlike the Scotch trout which according to Stoddart show a yearly increase of about one-third of a pound in weight,* in Otago they grow so rapidly and are so fat that they have reached an average yearly increment of from 1 lb. to 2 1 lb. Already the various streams have stamped the trout with local peculiarities : in some they are plump almost to deformity ; their proportions are not constant neither are their colours. He tells us that examples were said to have been seen up to 201b. in weight. This year, 1882, one 31 inches long and weighing 19 lb. was caught at Temuka, its flesh was of a pale orange : last year Mr. Grwatkin captured one in Canterbury, that turned the scale at 21 lb. The foregoing facts corroborate my views that all our forms of trout are varieties of one species, and the so-called hybrids are not mules but mongrels, being the result of the crossing of varieties. Consequently, sterility need not be anticipated ; but, on the contrary, improvement is more likely to ensue (should there be no deficiency in food) than when the stock is bred in and in. It also tends to show that where small, but not malformed, breeds of trout exist, riparian propi'ietors had far better investigate the condition of the food- supply and nature of the waters in their streams than rely upon the introduction of larger races. For, sooner or later, new stock will become indistinguishable from the original local breed in colour, form, and size. Hybrids. That hybrids exist among the Salinonidse and can be artificially produced by the pisciculturist, f I have already pointed out (p. 59). It was with much interest that I received in July, 1882, from Sir Pryse Pryse an undoubted hybrid between the brook-trout and the American charr (Salmo fontinalis). The example was 9 inches long, having the number of rows of scales descending to the lateral-line intermediate between the two forms ; the fins similarly modified, while a row of teeth passed in an irregular manner along the body of the vomer. The organs of generation were undeveloped, the example for this season at least was certainly sterile ; some American charr of about the same size, received a few days subsequently from Howietown, had the eggs and milt in a forward condition. Names. Aller-fioat or aller trout, this refers to a large one frequenting a hole in a retired or shady portion of a brook under the roots of an alder tree. In Herefordshire there is a country proverb respecting the " aul "or " alder :" " When the bud of the aul is as big as a trout's eye Then that fish is in season, in the river Wye." * "A correspondent of the New Sporting Magazine, for November, 1840, observes that a friend of his has kept trout in a kind of store stream, and having fed them with every kind of food, has had some increase from 1 lb. to 10 lb. in four years. Mr. Toomer placed a trout of 3 lb. which he caught in the river in a stew, and in about four years it had grown to about 9 lb." (Daniel, Rural Sports). At Howietown, a Loch Leven trout hatched in 1875 weighed over 8 lb. in October, 1882. f At Sir J. Gibson-Maitland's, November 14th, 1882, I was given a living hybrid 11 inches long, it was the produce of a Loch Leven female milted from a salmon on November 25th, 1879, and hatched in 1880, consequently nearly three years old, in fact a sterile grilse. 1250 living parrs in the boxes up to 4 inches in length, were the produce of 20,000 eggs of Loch Leven female trout milted from the salmon, December 24th, 1881, and hatched March 9th, 1882. Their dorsal fins had the anterior white edge usually seen in the brook-trout. One had 78 cuecal appendages, a second 61. 104 PHYSOSTOMI.

Bold, voracious, cunning and shy, it possesses keen sight, while it dreads anything novel it may observe. In some of our streams which are constantly fished it appears to have become almost insensible to the charms of the artificial fly, while, should it have been hooked, it would seem to remember the circumstance. When an outlying fish is disturbed it dashes away and seems to warn its neighbours by its flight. Sometimes it is so hungry that it appears to take almost anything : thunderstorms or darkness may cause it to cease from feeding. A correspondent of the Zoologist (1847, p. 2030) remarks upon a trout kept in confinement, and on a minnow being thrown in, it would immediately ascend nearly to the surface, hover over its prey like a hawk for a few seconds, then dash down and seize it by the head. The larger fish mostly move about in search of food of an evening and during the night-time, while they generally swim low, especially in cold weather. A favourite haunt is often behind a stone, or bank, while it appears to prefer a bush which gives shade from overhead. It requires moderately pure water, for a carp will live where a trout will die. It is alarmed by shadows falling over its haunts and the presence of pike, which take a heavy toll from these fish in some localities, prevents its feeding freely, causing its condition to be poor and the sport it affords to be small. It used to be said that chub drive out trout during the four hot months. If some trout esteem food which causes their flesh to be tinged with red, while others in the same water appreciate a different sustenance, and consequently are not thus tinged, if the Gillaroo eats shells, occasioning thickening of the middle coat of its stomach, while such diet, as a rule, is rejected by the common variety of brook-trout, it appears to point out that the tastes of some differ from those of their companions, while it is a well-known fact that certain forms of food promote fish-growth more rapidly than others. As already observed, those trout which principally subsist upon freshwater shrimps, Gammari, are generally of the most brilliant tints, and the most pinky-coloured flesh, while vegetable diet appears to genei'ally cause a silvery hue and sometimes a dull appearance. One about 1} lb. weight, taken in June, 1882, in the Tweed, was found to contain 11 small trout and one minnow. They do not object to small fish, as minnows, loaches, sticklebacks, &c, water-rats, young birds, frogs, snails, slugs, worms, leeches, maggots, flies, beetles, moths, and even water-spiders. They will even swallow one of their own kind two-thirds as large as themselves. In Mr. Bucklaud's museum existed an example, the stomach of which was distended by 2470 eggs of the salmon. They are out of condition subsequent to the breeding season, and in England Devonshire is considered one of the earliest counties in which they come into condition, and are fished for as early as the commencement of February. Elsewhere there are rivers equally forward. Parfitt found river mollusca, as Valvata picinalis, Blanorbis marginalis, Bhysa fontinalis, Lvmneus pereger, in the stomachs of some taken in May, in Powderham Park, Devonshire, but food varies with streams, &c. Means of capture. These may be either netting, spearing, tickling, poisoning, or angling. For the methods of netting these fish I must refer to the introduction. In the dry weather, at the Orkneys in 1882, the water in the Loch of Harray, on the west mainland, was induced in volume and rendered tepid by a succession of hot days. The trout assembled in shoals at the mouths of the burns and were slaughtered in thousands by netting. Spearing is not now permissible, although it used to be employed by torchlight. Tickling for these fish in small streams is occasionally employed with success. The angler has several modes of procedure at his command, if the fish are large, spinning bait may be employed ; or ground fishing with worms, or fly-fishing either with the real or imitation insect. Different rivers, seasons, and even periods of the day have their peculiar varieties salmonim;. 105 of winged insects acceptable to these fish ; as a rule if the water is clear and low, and wind is absent, small ones are most suitable : if clearing after a flood, or full but not discoloured the fly-fisher has more chance of sport, as well as if late in the season when few flies are born. When the water is opaque a worm or spinning bait may be tried with success. In small streams real flies and grasshoppers may be used as bait for hooks on a short line, which is bobbed on to the surface of the stream from over a bush. If once pricked by the hook it is generally but not invariably shy : while it is disturbed by flies clumsily thrown or splashing into the water. Frosty weather checks trout moving, and while snow water, or that derived from the melting of snow, is running into a stream it is almost useless attempting to use the rod. Baits. Worms as brandling, gilt-tail meadow worm, tag worm and red worm for a large one a well scoured dew worm. A minnow or any small silvery fish, a loach, or a bull-head with its fins removed. Breeding. The number of eggs produced by each female trout has been roughly estimated at 800 for every pound's weight of the fish, which computation has been observed at the Howietown breeding ponds to be fairly accurate. But the size of the parent exercises a considerable' influence on that of the eggs, thus in Sir J. Gibson-Maitland's fish house we found the following average numbers to be present along each line of grilles. Brook-trout 29 to 30 eggs ; Loch Leven trout, the parents of which were hatched in 1875, 27 or 28, or from those hatched in 1877, 32 eggs ; and the American charr 36 to 38.* The colour of the eggs are as various as observed in the salmon, and I have seen some orange, others straw- coloured, from two fish taken together out of the same stock pond. The period at which these fish breed varies in different rivers and districts, extending from September until February and even March. Mr. Harvie-Brown at Loch Gorm, in Sunderland, which is greatly fed by snow water from the Bact of Beumore, has taken trout heavy with spawn in June and July.f It has been questioned whether these fish are annual or biennial breeders, and Dr. J. Davy came to the conclusion, after examining a large number captured in open streams, that only half spawned annually. At Howietown, on the contrary, it would seem to be the rule that an annual spawning occurs, and though such a question is difficult to settle an instance in point has been observed. A marked example of Loch Leven trout was spawned at Sir J. Gibson-Maitland's on November 27th, 1874, and again on November 25th, 1875. At Howietown, where about one million of gallons of water flow through the ponds every twenty-four hours, the fish develop spawn and milt as regularly as in their native habitat, some even pass up the aerating channels forming redds there. But in ponds destitute of streams, certainly no young are produced, either spawn not being developed, remaining unfertilized, or else from being deposited in an unsuitable place (see page 91). It has been generally considered that when the ova of these fish have arrived at a certain stage the female has no power to retain them but they must be extruded, a conclusion Sir J. Gibson- Maitland has found reason to doubt, as it seemed to him that a certain amount of pressure is necessary to assist in the discharge of the eggs, and which is normally effected by pressing against the gravel forming the redds. Acting on this opinion he has found it possible to retard the extrusion of of the eggs for as much as a fortnight or even three weeks, by placing the fish in a wooden box through which a current of water flows. A trout's redd or nest is a mound of gravel which would fill one or even two wheelbarrows, and probably by causing a shallow, assists in aerating the water. The eggs themselves lie loose among the gravel at from one to two feet below the surface. Eggs w r hen shed are elastic, but soft and sink in water : when artificially propagated the milt of the male is generally added to the eggs in the pan prior to the addition of water, subsequently water is added and the mass is gently stirred * The rough calculation of eggs of Salmoniiia? is that Sahno salar gives 25,000 to the gallon, 8. levenensis 30,000, S- fario 40,000, 8. fontinalis 80,000. f Mr. Ugilby (co. Tyrone) observes that there is not a month in the year, during which it is legal to fish, in which trout do not spawn. 106 PHTSOSTOMI. with the hand. After a short period the eggs become adherent but gradually absorb water, distend and are like little round balls. The period for which milt will remain serviceable after removal from the fish is an interesting subject. On October 23rd, 1874, some was obtained at Howietown at 9 a.m. from a Salmo fario, then carried to Loch Leven in a tightly corked tube, and used at 1.20 p.m., the impregnation being perfect. Ova or milt may be kept alive for some hours, but on the addition of water, death rapidly occurs. Respecting the artificial propagation of these fish, I think I can do no better than give a summary of the excellent article on " stocking," by Sir J. Gibson- Maitlancl. Skill and knowledge are requisite in order to select the fish from which the milt and the ova are to be collected, and likewise to ensure perfect impregnation. The ova should be laid down on glass grilles in the hatching boxes from whence dead ones can be readily removed before the fungus which grows upon them has time to damage by spreading to such as are in its vicinity. When the eyes of the embryo commence to be visible an increased supply of oxygen is necessary. When the embryo is sufficiently developed to enable the eggs to be handled with impunity, they may be packed in trays, on damp swans- down, and forwarded to their ultimate destination. Care has to be taken that the water for the hatching-house is constant in its supply, equable as to its tempera- ture, and not loaded with sand or any impurities, that frost is kept out, and though early eggs are the best, eyed ova should not be sent to a cold locality where it would have to battle with one or two months' continuous frost, on the other hand transmitting it to a warmer climate care must be taken to meet the tempera- ture en route which almost of necessity sets the eggs hatching. These eyed eggs are turned down into artificially and carefully constructed redds, scattered all over the district in close proximity to the best feeding grounds and ripples for the fry. Such absolute purity of the water flowing over the redds is not required for eyed ova as it is for the eggs prior to this period, still discoloured water should never be employed. It is also requisite that the redd be situated near a stream of less pure water, as the absence of fine particles so necessary for the health of the embryo, is not satisfying to an active young trout of a few weeks old. A natural river temperature of 50 will always produce ample food for the young fry. Prior to the absorption of the umbilical sac they should not be placed in ponds or muddy water. They will not bear much handling but bear carriage very well : a 40-gallon tank being sufficient for the conveyance of about 15,000 which have been feeding for more than a month, except for very long journeys when a supplementary small tank requires to be added, which altogether saves the necessity of handling the fry. They can be reared in small properly constructed ponds and subsequently turned into deep water. The normal period eggs take hatching is found when the water is kept at about 4410 degrees to be as follows at Howietown : Salmo fario, 71 days ; S. levenensis, 72 ; S. fontinalis, 73 ; 8. levenensis crossed by S. salar, 75 ; and 8. salar, 77 days. But as already observed lowering temperature delays hatching, increasing it hastens such on (see pages 65 and 107). For the purpose of stocking pieces of water with trout, either eggs or young fish may be obtained from a breeding establishment. It is highly desirable, prior to receiving such, that a careful examination should be made that the nurseries do not contain their enemies, as bull heads, Cottus gobio, which will eat them as rapidly as it can find them. At the Howietown fishery* it is suggested that streams with sediment in the water or a liability to floods are unsuited for depositing ova, and fry are recommended instead. In transmitting ova those which are partially eyed are recommended, and are laid down in gravel redds in some small streams contiguous to the rivers or lakes it is desired to stock. Eggs being kept in glass grilles give the strongest embryos and healthiest fry. The time necessary for preparing young trout for transport varies from three or four days in the case of yearlings, to as many weeks for large examples. The * Circular, dated Howietown, Stirling, 1882. SALMONIDiE. 107 yearlings are sufficiently strong to find their own food, thus avoiding the principal cause of mortality among fry, which is starvation. They soon accommodate them- selves to new pieces of water. Two-year-olds are found to succeed best where coarse fish or large fish already exist in the water. It has been found that there is no difficulty in conveying trout in iced water for any journey not exceeding twenty-four hours. That unless the water which is to be stocked is of similar temperature some loss will arise from inflammation of the gills, they are consequently carried best in cold weather. Hybrids. At Howietown the following crosses were made : November 27th, 1874, between a female Loch Leven trout and a male sea-trout, they hatched March 20th and 21st, 1875. On December 3rd, between a female common burn or brook-trout and the milt of the sea-frrout, they hatched March 21st, 1875. Sea- trouts' eggs with burn trout milt commenced to hatch on the 116th day : the young have become indistinguishable from the common stock. On November 15th, 1882, Sir James Gibson-Maitland commenced the following experiments at Howietown while I was present. 8000 ova of Salmo fontinalis were milted from a S. levenensis, and were placed in hatching box no. 104. 3000 ova of 8. levenensis were milted from a S. fontinalis and deposited in box no. 108. 9000 ova of S. fontinalis were milted from a charr which has been termed 8. struanensis, and placed in box no. 115. Life history. All the various forms of trout have their parr stage. The normal rate of growth in the ponds at Howietown I have already alluded to (see page 103). Mr. Stoddart gives the result of an interesting experiment on young trout : " Fish were placed in three separate tanks, one of which was supplied daily with worms, another with live minnows, and the third with those small dark-coloured water-flies which are to be found moving about on the surface under banks and sheltered places. The trout fed on worms grew slowly, and had a lean appearance ; those nourished on minnows which, it was observed, they darted at with great voracity became much larger ; while such as were fattened upon flies only, attained in a short time prodigious dimensions, weighing twice as much as both the others together, although the quantity of food swallowed by them was in nowise so great." The size to which they attain depends upon the suitability of the water inhabited and the amount of available food. Thus in some mountainous districts they may never exceed 3 or 4 ounces in weight, while young hatched from the same batch of eggs may attain to pounds. They are a long-lived fish : one was twenty-eight years in a well in Dumbarton Castle ; another is said to have been fifty-three years in a well in the orchard of Mr. Mossop, of Board Hall, near Broughton-in-Furness. As food. Its value differs with the waters from whence it has been taken. Its old name was " the venison of the waters," and denotes the general estimation in which it was, and is still, held. It is in the best season from May until the end of September, deteriorating in and after the breeding period. Some consider the females as food to be better than the males. Habitat. The colder and temperate portions of the northern hemisphere, descending in Asia as far south as the Hindoo Koosh, but not normally present in any portion of Hindostan. Heber, mistaking a spotted carp, Barilius, for a trout, asserted they were found on the Himalayas, on which authority Couch gave India as one of its habitats. It has been introduced on the Neilgherry range of hills in Southern India. It has been artificially introduced into many countries in the southern hemisphere. In the Orkneys it is found in great plenty in every burn, and generally extended throughout the rivers and lakes of the British Isles when unchecked by pollutions. Some exceptions, however, to this general rule would seem to occur, thus in Norfolk, we are told, it is found in small numbers in the higher parts of the Bure, the Ware, and some of their tributaries, but not in the Waveney (Lubbock). A trout upwards of 21 lb. and measiiring 41| inches in length, was taken in a small tributary of the Trent at Drayton Manor, and sent by Sir Robert Peel to Yarrell. In 1880 Buckland made a cast of one 17 lb. weight, captured at Reading. July 11th, 1882, one 20 lb. weight was secured in Lough Derg, an expansion of the Shannon (S. Hurley). 108 PHYSOSTOMT. B. Vomerine teeth restricted to near the head of that bone (Salvelini). When treating of the group Salmones (p. 53) I gave a short synopsis of the views held by our later naturalists respecting which each considered to be species or referred to varieties. I propose taking the same course with the charrs Salvelini. Willughby (1686) places under one head JJmbla minor, Gesner the Reutele of South Germany, the Torgoch of Wales and Westmoreland, and the red charr of Windermere, table no. 7. He also alludes to the gelt or gilt charr of Westmoreland, which he refers to Garpio lacus Benaci of Rondelet ; he likewise figures it table no. 5. Ray (1713) held the same views as Willughby. Pennant (1776) figures the charr, and asserts his opinion that the case charr, the gelt or silver charr, i.e., one which has not spawned the preceding season, and on that account is reckoned to be in the greatest perfection, the red charr, and those of Loch Inch in Scotland, are all probably one species. He observes that the variety case charr spawns about Michaelmas, while the gilt charr does so from the beginning of January to the end of March. He also alludes to the Welsh charr. Donovan (1804) gave a figure of what he considered the gilt charr of Pennant, Salmo alpinus, Linn. ; also a plate of Salmo savelinus, Bloch, the torgoch of the Welsh, then said to be confined to the waters of Llyn Cawellyn, one of the Alpine lakes situated in the deep valley on the west side of Snowdon. He considered that it differed from the charrs of Windermere. Turton (1807) agreed with Donovan, as did also Fleming (1828). Jenyns (1835) held the same opinions, but termed the Alpine charr of Donovan S. umbla. Yarrell (1836) held the same views as Jenyns, but in his second edition (1841) as well as in his third (1859), all our British forms are held to be varieties of one species. Agassiz (1834) believed that all our British forms were identical with the Ombre chevalier of the Lake of Geneva. Richardson (1835) placed (1) 8. umbla as synonymous with S. alpinus and S. salvelinus of Linnams, and also with the species found in the Lake of Geneva, but he desired his readers to remember that the history of the charr, whether one or more kinds, had not up to that time been clearly made out. In Windermere he considered that the case charr ascended rivers, spawning about Michaelmas, while the red charr deposited its ova along the shores of the lake, and not until the end of December or the beginning of the year. Parnell (1838) classed our northern charr as S. umbla, Linnseus. Thompson (1840), and subsequently in 1851, held that all the forms of British and Irish charr are varieties of one species, the 8. umbla, Linnaeus. White (1851) placed all the British examples in his catalogue of the fish in the National Museum as pertaining to S. umbla. Dr. Giinther (1866), as in the Salmones so in the Salvelini, has largely augmented the number of what he considered British species, although he rejects 8. umbla and S. salvelinus as British forms. He gives (1) 8. alpinus, vertebrae 59-62, ccecal appendages 36-42 ; (2) 8. Jcillinensis, vert. 62, coec. pyl. 44-52 ; (3) S. Willughbii, vert. 59-62, coec. pyl. 32-44; (4) 8. perisii, vert. 61, ccec. pyl. 36 ; (5) 8. grayi, vert. 60, ccec. pyl. 37 ; (6) S. Colii, vert. 63, ccec. pyl. 42. Sir J. Gibson-Maitland (1881) added 8. struanensis. 8. fontinalis, or the American charr, has likewise to be added to the British forms, being now extensively distributed throughout the country. Up to 1866 Pennant, Agassiz, Yarrell, and White admitted one form of charr as British, while Donovan, Turton, Fleming, and Jenyns believed in two. Giinther increased them to six, subsequently S. struanensis was added, and the American charr widely propagated. Widegrem (1864) asserted that in Scandinavia there exist two races of charr, the larger being found in Lapland, Lake Wetter, and other lakes ; while the smaller is present in pieces of water of less size as those of Jemtland, Wermland, SALMONIDiE. 109 Smaland and Norway. These two races lie held to be simply modifications of one species, Salmo alpinus, the stebling of South Germany of which 8. umbla is a synonym. Holding these opinions which were identical with those of Agassiz and others, he entered his protest against the validity of Dr. Giinther's new species, which he deemed as merely so many additions to the synonymy of S. alpinns. Collett, Norges Fiske (1875), considers all the charr to pertain to one form, so also does Malm, and Moreau in his Fishes of France (1881) arrives at the conclusion that all the charrs of that country are a single species, S. umbla, which he considers identical with S. salvelinus. In the Zoological Record of 1864, Dr. Giinther disputes the possibility of the size of the teeth having any bearing on the food these fish consume, maintaining that such may even be a reason towards instituting a species. However, in the artificial reai"ing of Salmonoids it has been found that some young do take on cannibal propensities and are furnished with larger teeth than then 1 neighbours. Referring to the size of the eggs Dr. Giinther likewise differs with the Scandinavian zoologists, holding that those who may have a more extensive knowledge of fishes " know that the size of the ova is not only invariably the same in individuals of whatever size, but, as far as our experience reaches, is even often characteristic of the species of a genus." Here I must refer to page 105, where I have shown that the size of the eggs may depend on the age of the fish. There appear to be three different main reasons for dividing the British charrs into several species, the colour, the number of vei'tebros, and of the ccecal appendages. The colours in the charr do not vary to so great an extent as they do in the trout, due to their residing in deeper waters and usually merely ascending towards the surface at night time to feed, while other changes in tint are consequent upon the breeding season. In the Lakes of Cumberland, Westmoreland, and Lancashire, observes Jenyns, this fish in its ordinary state is the case charr of Pennant ; when exhibiting the bright crimson belly which it assumes before spawning, it is called the red charr ; when out of season the spawn having* been shed, it is distinguished by the name of the gilt charr. Thompson observed that he had examined in a fresh state charr from Windermere, from Lock Grannock (Scotland), and Lough Melvin (Ireland), and preserved in spirits or dry from nine other lakes in Scotland or Ireland. Examinations of these led him to believe that there exists but one species : one, however, that like the Salmo fario is subject to extraordinary variety. In one lake the male fish can at a glance be distinguished from the female either by colour or by the many characters which are comprised under " form." In another, so similar are the sexes in every external character, that without the aid of dissection they cannot be determined. In size we find the species ordinarily attain twice the length and several times the weight in one lake that it does in another, although the area of their waters is of similar extent ; indeed, in some of the largest lakes this fish will be found not to attain near the size it does in some others, which are but pools in comparison ; there are, however, various influences which account satisfactorily for such differences. In the form of the body again, we find the species, when in equally high condition, to be in one lake herring-like and in another approximating to the roundness of the eel. So manifold are the differences presented by the charr from various localities, that it would be tedious and perhaps useless to point them out in every case. A correspondent in The Field (April 22, 1882), speaking of the white trout of Quebec, observes that the best authorities seem to agree that the sea-trout of the provinces is simply a Salmo fontinalis that has migrated into salt water and changed its colour by that means. This leads us to inquire whether we ought to agree with Agassiz, Thompson, and others that the number of species of charr in these islands is limited to one which is subject to great variations in form, in colour, and other characters due to physical causes ? Or should we adopt the theories of those who see at least half-a-dozen species in the British Isles, and anticipate many more being discovered when the lochs of Scotland and the loughs of Ireland have been exhaustively explored ? The number of vertebras. The six forms described by Dr. Giinther are said 110 PHYSOSTOMI. to have these varying between 59 and 63, but as in type examples of two forms in the British Museum we are informed from 59 to 62 were present, the existence of an additional one in a specimen of 8- colii can therefore hardly be a reason for instituting an additional species (see page 55). The number of ccecal appendages. The extreme variation in all the foregoing six species is given at from 36 to 52, while we are informed that in 8. Willughbii from 32* to 44 are present in examples in the National Collection. I have already shown how inconstant are the numbers of these appendages among the Salmonidae (see page 56). If we seek to investigate the history of these fishes from the earliest times, and inquire of geologists as to what account they are able to furnish, we are told that the Salmonido3 are a comparatively recently evolved family, their very existence in a fossil form (if we exclude Mallotus) being unknown. Mr. Symonds, in the last edition of the Records of the Rocks, observes : "I have fished in and visited many of the lakes in Great Britain, where the charr, Coregoni, and great lake-trout (Salmo ferox) are known, but I never saw one in which they still exist that is not either a glacier lake, or rock basin, or that is not dammed or otherwise surrounded by glacial moraine matter. They are also inhabitants of the lakes of Sweden and Norway, which everywhere bear traces of the glacial epoch and its close, and seem to me to be (like the Alpine plants that still linger among the mountains) fishes of that colder period when the last of the glaciers still hung to the combes of the Highlands of Scotland and Wales." Doubtless the charr prefer the colder north to the more temperate portions of the globe ; and moderately still waters. Among the fishes brought by the late Arctic expeditions were examples of charr very similar, if not identical with British forms, thus seeming to show a near relationship one with the other. While in Nordenskiold's Arctic voyages it is recorded that the young of S. alpinus, three inches long, were captured on the eastern side of Wijde Bay in June, 1861. Mr. Brooke, writing respecting a species of Irish charr, observes that " Lough Eske (where it was captured) was the crater of an extinct volcano, as suggested by Dr. Wilde, of Dublin." Many and various reasons have been advanced by different persons against the enactment of laws for the protection of fishes, especially charr, and I observe that Mr. Houghton, in his British Freshwater Fishes, considers that "the extension of the Salmon Act to charr is a great mistake. The only time and that time is of short duration when charr can be taken in any numbers is in October and November, when they leave their deep-water haunts for the shallower parts of the lakes. The destructive agency of man, limited as it is to one or two months' duration, could have but little effect in causing a diminution of the species in the extensive depths of our great lakes, which, for five-sixths of the year, provide safe and unassailable harbours." On the other hand it has been asserted that the charr of Lough Neagh, in Ireland, have been exterminated by man within the last forty years, showing his power, when unchecked by legislative enactments, of effectually accomplishing such a destruction. In Land and Water for December 27, 1879, is an interesting article upon the result following the preservation of the Llanberris charr. Two large freshwater lakes exist, joined together by a small river. In November the charr pass up this stream to the lower portion of the upper lake to spawn, having accomplished which they return to the lower lake. The proprietors, acting on the principle enunciated above, used to net them at the spawning period ; but the Salmon Act of 1873 prohibited the capture of these fish between October 1 and February 1, so the killing of these spawning charr has been stopped. Prior to 1874 they were only to be seen here and there in shoals of a score or so, whereas now they may be observed in hundreds, averaging about nine fish to 2 lb. weight. In September, 1879, an angler, with a worm bait, captured in one evening 23 lb. weight of charr, and as soon as the news got abroad many others took to angling for these fish, and all * I have examined one from the Lakes which only had 28. SALMONID^E. Ill had good sport. This continued until close-time, and some days hundreds of quarrymen might be seen fishing, some in boats, others from the shore, while as much as 45 lb. a day has fallen to the share of one rod, a bait having been almost invariably used, although a few were taken with a fly. A correspondent of The Field, October 28, 1882, remarks upon night fishing for charr with well scoured brandlings and line tackle in North Wales. All is done by feel, and, when a vigorous tug occurs at your line, one has to strike; at the approach of day the charr begin to bite savagely, as dawn commences the biting ceases, and the fish disappear as if by magic. Respecting the Windermere fishing for 1881 it was remarked in Land and Water, November 26, 1881, that the charr fishing was, as usual, very profitable. There can be no better argument in favour of a close season and protection than the great increase in the value of the charr fisheries since such was applied and protection afforded to the fish. The mode which is generally carried on by the fishermen as described in The Field is with what is termed a plumb line, which is free to all, and a great number of the natives on the shores of the lake gain a good livelihood by supplying the strangers and hotels with the fish. Charr fishing with the plumb line usually commences about the beginning of March, and at that time the fish are got about thirty yards from the surface and in the deepest parts of the lake. As the weather gets warmer they gradually approach the top, and although they are frequently to be seen on a warm day leaping at the flies on the water, yet it is an unheard-of thing on Windermere to cast for them with a rod. The plumb line for charr is made of strong cord, and varies in length according to the number of baits which are to be put on it ; but it is usually between forty and fifty yards long, and this is sufficient to carry five baits. At the end of the line is a lead sinker, weighing about If lb., having a small wing fixed in it, which assists in preventing it from revolving, although it is fixed to the main line with a strong swivel. To this line is attached at intervals of six or seven yards, short lines, or, as they are called by the fishermen, droppers, varying in length from six to ten yards, the shortest line being that nearest the bottom of the main line. What is generally used at Windermere, is a " phantom " made by the fishermen themselves, from sheets coppered on one side and silvered or clear on the other, which can be procured from any coppersmith or ironmonger. The fishermen cut them out with a pair of strong scissors, shaping them to their taste. A small treble hook is put on the phantom, and two yards of strong gut, having at least two swivels, and the remainder of the short line, or " dropper," may be of fine cord. Two lines such as are here described are always used in fishing for charr, one on each side of the boat. Having reached the fishing ground, the boat must be rowed slowly, and the sinker is put over tbe side, and the line allowed to sink until the dropper next to it is reached, when the main line is temporarily fixed, until the " dropper" and phantom is put out ; the main line is then loosened and sunk further, until the next " dropper " is reached and put out, and so on until the whole line is out. This having been done the end of the main line is attached to the top of a strong rod (a young sapling does very well), about fourteen or sixteen feet long, supple at the top, but not too much so, and then the rod is made to rest over the stern of the boat at the side upon which the line has been put out, and the butt end securely fixed in the bottom of the boat. When this has been done the second line may be put out at the side of the boat, in the same way as the first line, and secured with a rod. Care must be taken to have the boat always moving, other- wise the lines will foul. It would appear that the preservation of charr leads to a substantial increase in their numbers, and augmentation in the food-producing property of the lake where such is carried out. While these fishes are not so very indifferent to bait and flies as some persons would lead us to believe, the angler with a bait appears to have more chance of sport than the fly-fisher, but the charr of Windermere usually will not rise to the fly, while the Welsh torgoch takes it freely. 112 PHTSOSTOMI. Mr. Harvie-Brown informs me of a chain of loc-hs in Scotland containing charr. In one small, deep pool of crystal-clear water they are of a larger size than those inhabiting the lochs lower in the valley. In a perfectly dead calm they rise, sometimes freely, to a certain fly, but cease whenever a ripple disturbs the surface. As many as six dozen have been taken by one rod in a single day. One can see several feet down into this basin of pure water in a calm, and perceive the fish floating upwards and sucking in the fly, as they seldom dash at it like a trout. Charr, says Mr. Jackson, except for a few weeks in the year when it appears to live on flies, preys on all small fish and captures them, even larger than would be supposed possible by any one who has not taken (as I have) a perch nearly two inches long out of a charr about nine inches in length. 3.

Thompson observes of the charr of Lough Melvin, that " the males are generally more gracefully formed than the females, and most of them are rather brighter in colour, but there is no external character so strikingly different as to lead to a certain knowledge of the sex : some of the largest finned are females." They are termed "fresh-water herrings " in Lough Melvin. When cooked the flesh is pale and its taste insipid. Breeding.

Eyes size depends much on age, sex, and nature of locality from whence procured : usually situated just in front of the middle of the length of the head, from l to 2 diameters from the end of the snout and the same distance apart. In some the comparative height of the body is much greater than in others, and dependant on food, health, and the vicinity of the breeding season, the kelts becoming emaciated. The maxilla in some extends to beneath the last third of the orbit, in others to beyond the vertical from its hind margin, while it SALMONID^] 115 is likewise slightly more strongly developed in some than it is in others. The lower jaw in some varieties, as the torgoch of Wales, may be longer anteriorly than the upper jaw. The opercular pieces are of as diverse shapes in the charr as described in the trout, and frequently are dissimilar in the opposite sides of the head. Teeth present in the jaws and in a line across the vomer near its anterior extremity, and opposite the teeth of the palatine arch, none along the body of the vomer. Fins dorsal usually commences about midway between the end of the snout and the base of the caudal fin, in some examples a little nearer the snout. The pectoral and other fins are of varying lengths in accordance with locality, sex, and other varying conditions. Scales small and a much larger number of rows descending from the back of the lateral-line, than there are of pierced rows along its whole extent (see below). Cuecal appendages these vary considerably, in Loch Inch 38 (Thompson) ; L. Rannoch, 28 ; the Lakes, 28-44, Dr. Giinther detected from 36 to 52, and the smallest number in those from Windermere, 36, from the same locality I possess an example with 28, and found the same number in a specimen received as $. struanensis. It is evident they are as inconstant as in the trout. Colours these again vary, but as a general rale the belly, prior to spawning, becomes of a crimson or claret colour, while there are generally some light-coloured orange or black spots on the body and head. The front edge of the dorsal, ventral, and caudal as well as the upper edge of the pectoral are often of a pare white or orange colour. The variation in tints and shades are not so great as in the trout (see page 109). In some, the ventral, anal, lower portion of the pectoral, and hind edge of the caudal partake of the scarlet colour of the abdomen. Varieties in colour. " By such alone," observes Dr. Giinther, " fresh specimens of Salmo salvelinus and S. umbla, of S. Grayii and S. Willughbii, may be always distinguished," and in his interesting division of the British species into many, he divides it first in accordance with the development of the jaws and size of the teeth, an inconstant character, as I have observed (page 109). It is then sub- divided in respect to the length of the pectoral fins : but here it is evident that the question of sex, locality where hatched and reared, and many other local circumstances, must be taken into consideration. I examined eight specimens received from the lakes, and found as follows : All were from 8^- to 9 inches in length ; in two the pectoral extended just half the distance to the base of the ventral, and in the remainder If, 1 T 3 T , l|i, If, 2 T \-, and 2^ in the interspace, clearly showing that this is not a character on which too much reliance should be placed. The next subdivision is into whether the dorsal fin contains 13 or 14 rays. Such an enumeration is evidently open to uncertainty, unless it is taken into consideration and recorded how many undivided and how many branched rays are present. The first few which are undivided are minute, one or two may even be wanting. Thus in the 8 examples from the same locality already referred to I found from 3 to 4 undivided, and 9 to 10 divided rays in the dorsal fin, and similarly in the anal, 3 to 4 undivided and 8 to 9 divided rays. Moreau, in France, finds D. ^ s 5 , A. -flf. This character, therefore, is unreliable. As to the comparative height of the body that varies with sex, season and food, and cannot be otherwise than a very uncertain element in the discrimination of a species. As regards external characters, Dr. Giinther observed (1862) that " dried and stuffed specimens of charr are of little or no use." One would have supposed from this that the colours, scales, and size of the fins would afford no criterion as to species. In 1864 the same author remarked that" the difference in the size of the scales is one of the most constant and important characters in salmonoids." In examining numerous examples of Salmo fontinalis reared in this country, one cannot resist being struck with the considerable differences which occur as to the number of the scales, and the consequent inconstancy of this factor as a criterion for-species. Taking the pierced scales along the lateral-line, I possess specimens which have from 122 to 142 : but it is in the number of irregular rows which descend from the back to the lateral-lino where the greatest diversitv occurs, 8 * * 11 G PHYSOSTOMI. while it is here that Dr. Giinther counts. Although in 8 of my British examphs the difference in the number of pierced scales along the lateral-line does not exceed 20, I find from 185 to 235 rows descending to the lateral-line, or a variation of 50 scales. Taking the whole of the reputed British species, the extreme variation recorded is 70 rows. If, therefore, among 8 examples of American charr received from two localities I can observe a difference in number of at least 50 rows of scales descending from the back to the lateral-line, the extreme variation of 70 among specimens of charr obtained throughout the extent of Great Britain and Ireland appears hardly sufficient grounds for instituting distinct species. Sir W. Jardine considered that " the northern, or Sutherland charr," has more elon- gated scales than the " southern charr," the scales of which he described as being more orbicular. " The charr of Hawswater," observes Dr. J. Davy, " which is known to feed a good deal on insects, is a small and slender fish in comparison with the charr of Windermere, which feeds more at the bottom and has a less precarious supply, especially of Squillce, which abound in the lake. The one takes the artificial fly freely ; the other that of Windermere is rarely so tempted and seldom caught, except by trolling with the minnow. In short," he remarks, " so various are they that in no two lakes do they perfectly agree, either in their average size, form, colouring, or even in their habits." In examining 8 examples from the above locality I found the following variations : D. g 3 _ T 4 o, A. flf, L. 1. 118-128, Ccec. pyl. (in one example) 28, (32-44, Giinther). The number of rows of scales descending to the lateral-line varied from 166 to 180. Passing on to the Loch Rannoch charr, S. struanensis (Maitland), we see certain differences present (see plate cxvii, fig. 2). D. f, A. f:f , L. 1. 120, Ccec. pyl. 28, 160 scales descended from the back to the L. 1. The fins in some examples are more developed than in others, and may be said to be in many respects intermediate between S. alpinus and 8. killinensis, but the most peculiar feature is the dark colour of the specimens. Among the examples sent to me by Sir J. Gibson-Maitland was a common trout from Loch Rannoch, which showed the same dark colours and well-developed fins. The eye in some of these charr was rather large, which, taken in conjunction with the dark colours of the body and somewhat developed fins, would seem to indicate its living at some considerable depth. Names. Charr or char. Torgoch ("red belly"), Wales. Bed-wame, Scotland. Jj 'ombre-chevalier, French. In olden time the credulous were taught that three sons of the Church intro- duced these fishes into Wales from Rome, and placed two in each of the Lakes of Llanberris, Llynumber, and Trevennyn. Habits. A gregarious and usually deep swimming fish, shy of taking a bait and feeding largely at night-time. The common food of the trout has been found in its stomach, while when in confinement it can be similarly fed. It appears to require very pure and mostly deep water for its residence, but is found in some Irish lakes which are not very deep. It has been observed to have disappeared from some lakes due to the entrance therein of poisonous matter as from lead mines,* but in other localities where no such deleterious substances have obtained access, as Loch Leven, and some of the Irish Loughs, it has been suggested that such may be dependant upon the diminution or disappearance of such entomostraca as previously formed its natural food. It does not bear confinement well, but may be kept for a short period in troughs through which a supply of water flows. Thompson, in 1835, observed that they were thus kept at Coniston water at the hotel and sold at 10s a dozen. Charr have been accused of destroying the eggs and young of the trout. Knox found in examples from Windermere some entomostraca. Sir J. * It has been stated to descend to the sea, and it has been asserted that some were captured there or at the mouths of rivers on the Welsh coast after they had been driven out of Llauberris by poisoned waters. Further evidence on this point is required. SALM0N1XVE. 117 Gibson-Maitland found the food in the stomach of all he examined from Lake Rannock distended with water fleas, Daphnia pidex. Thompson found in some from L. Inch that their stomachs were crammed with insect larva?, entomostracous Crustacea, a small Notonecta or boat-fly, bivalve shells of the genus Pisidium, and minute gravel. Means of capture. Fishing by bait is best in spring, but is carried on throughout the summer: very fine tackle is necessary. The best places are the deepest parts of the lake. They come in autumn into shallow water (see pp. 110, 111, 112). Baits. -The artificial fly, spinning minnow, or spinning spoon, worms. Breeding. Dr. J. Davy found 1230 ova in an example weighing about half a pound, and that the principal spawning season in the lake district is from about the first week in November to the first in December. Whether, he observes, this is the only season is somewhat doubtful, as the fishermen at Windermere speak of a later one in which it is believed by them that fish of the larger size and few in number deposit their spawn in February and March. He "never heard of one being taken or seen in the Brathay after December." The locality chosen for forming a redd is in gravelly shallows in the lakes. They rarely ascend streams towards their source to spawn, but restrict themselves to near their outlet or portions where the current is not very rapid although a shallow is necessary. Thompson observes respecting the time of breeding, that the Loch Killin charr contained ova the size of peas on September 26th or 27th, whereas in the neighbouring lake of L. Corr they were in high condition. This is one out of numerous instances which might be adduced respecting the different periods of spawning in contiguous localities. In Bavaria in the Kcenigsee, near Berchtesgarten, some of these fish taken at the latter part of Jane, July and August were found ready for spawning. Dr. Davy informs us that Mr. Reynolds, in 1850-51, found none hatched in less than 60 days, the greater number on the 70th, and from that to the 75th, and some few as late as the 90th : the average temperature in the breeding boxes being about 40. At about 55^ the process has been completed in 41 days, and there were some of the same eggs took 90 days in Mr. Reynolds' hatching boxes. Some eggs of the lake-trout were fertilized with the milt of the charr and commenced hatching in 70 days. It was found by Dr. J. Davy that running water is not essential to the development of the eggs of the charr, from which he concluded that its breeding place being distinct from that of the trout it is not likely to give rise to hybrids. " That salt water, even of greater saltness than sea water, is not immediately fatal to the embryo, even when not included in its shell : moreover, that in slightly brackish water a partial development of the ovum may take place, and that the young fish can exist some days in such water, rendering it probable that the adult may be capable of existing in a tidal stream or even in the sea, where it is stated that the Welsh charr has been caught." Life history. The young when artificially reared appear to be somewhat more delicate than the trout. In Austria it is observed to grow much more rapidly in some lakes than it does in others. Yarrell states that in the autumn of 1839, Mr. Upton, near Sedberg, put into the Lillymere Lake, near the reservoir, some charr taken from Windermere, each weighing about \ lb., and on August 23rd, 1840, took with a fly two 2 lb. weight each, in the finest possible season, well fed and beautifully coloured. Hybrids. In Upper Austria, C. Peyrer observes a cross between Salmo salve- linus and the brook-trout is propagated and excels the pure breed in many respects, the eggs of the former are milted from the latter. I have seen two specimens of hybrids over two years of age, the one between a salmon and a Loch Leven trout, the other between an American charr and a brook-trout ; both were sterile, but as to whether merely temporarily or permanently I cannot offer any opinion.* * Lenchart observes upon hybrids between the salmon and brook- or sea-trout that his experiments led him to conclude that the hybrids are fertile and their offspring not sterile. And Professor Haack has fertilized the ova of hybrids between charr and trout with the milt of trout (see p. 59 ante). 118 PHYSOSTOMI. As food. The flesh of these fishes varies, in some localities it is pink in colour, in others white. At the lakes they are in the greatest perfection from July until October. As they soon lose their delicate flavour after removal from the water they are potted and thus considered a great delicacy. Habitat. In Norway the red charr lives from a sea level up to 600 metres above it : in the S.E. portions of the country it is rare, in West Norway more common and captured in large numbers with a fly. Its flavour varies as greatly as does that of the trout, and it appears to thrive best in lakes where the temperature is somewhat uniform, without bottom springs and not having too large an amount of brook-water flowing in. It extends to Great Britain and Ireland, France, Southern Germany, and in the clear lakes of the Alps of Upper Austria, Tyrol, Bavaria, Switzerland, also in the Carpathian lakes up to 6000 feet above the sea. The Orkneys, being occasionally captured in Loch Stenness, and three were obtained in Waas, in 1832 (W. Baikie) : also from North Uist in the Hebrides. Examples from Sutherlandshire are in the British Museum, while Mr. J. Harvie- Brown informs me that there is a charr loch about twenty-five miles from Durness, on Ben Hope, where they are taken up to 1^ lb. weight. At midsummer they are only known to rise at one part of the loch, on its S.E. side, between the exit of the stream and the island. In September numbers are taken with both worm and fly. Mr. Bantock says that charr abound in scores of the Sutherland- shire lochs, and mentions the one referred to on Ben Hope, and another small loch (Borley) near the Manse at Durness ; they are also found in the upper end of Loch Assynt. Thompson recorded their existence and obtained specimens from Loch Corr, Loch Moy and Loch Killin, Inverness-shire. Specimens from Loch Dochart, in Perthshire, were in the British Museum according to White, and Sir J. Gibson-Mai tland has taken them in Loch Rannoch. Pennant recorded them in Loch Inch, Wigtownshire, and Thompson in Loch Grannoch, Kirkcudbrightshire. Also an example from Loch Bruiach is in the national collection. Black, 1844, observed that this fish had of late years disappeared from Loch Leven. In England the lake districts of Cumberland, Northumberland, and part of Lancashire, more especially in Windermere, Keswick, Crummoch Water, Butter- mere, Ennerdale, Coniston Water, Westwater and Hawswater, the area of which is estimated at 35,320 acres, are those where charr do or did frequent. Winder- mere, we are informed (1878), is very productive, while in Coniston the fish have been poisoned by the mines ; they are also found in Rydal. In Windermere they are somewhat restricted to the deep waters, and spawn in the River Brathay, avoiding the Rothay, which is more frequented by trout. Some spawn in November and some are said to do so in February. In Wales this fish is still found near Snowdon, in the Lake of Llanberris, Llyn Cawellyn, Coss-y-gedawl and Bettew Festiniog in Merionethshire. In Ireland. In the county of Donegal it has been taken in Lough Esk (Camden), also from near Dunfanaghy (Templeton), L. Gartan, L. Kindun, L. Shessuch, L. Keel (Thompson), and L. Derg (Field, June, 1879), and L. Elvyn (Couch). In Antrim from L. Neagh (Dubourdieu) : Thompson visited this place in 1834, and was informed that none had been captured for the last ten years, although twenty years previously they had been abundant. An old fisher- man explained the reason as follows : " That they once went down the River Bann to the sea and never came back again." In Monaghan at Lough Eaghish (incorrectly spelt Esk) according to Templeton, who stated they had become very rare and were all but extinct. In Fermanagh at Lough Melvin and L. Erne (Thompson), Westmeath in Belvidere Lake (Ball), county of Cavanin Drumlane Lake (Thompson) ; in county of Mayo, Castlebar (Daniel) and Lough Conn (Pack) ; county of Galway in Lough Corrib, and L. Bonn (Thompson), Longford at Lough Nabrach (Ball), Connemara in Lough Ourad (Davy), Wicklow in Lough Dan (Thompson) and L. lada (Couch), Waterford in four mountain lakes (Smith), and at Inchigeelagh in the county of Cork (Vyse). In figuring all the reputed species of British charr, as much as possible, examples have been selected in the National collection in order to prevent the SALMONID^E. 119 possibility of any error of identification occurring. In the Lake districts they average from 1^ to over 21b. but they have been obtained many pounds heavier in weight. 4. Salmo fontinalis, Plate CXX, figs. 1, 2. Salmo fontinalis, Mitchell, Trans.

Length of head 4t\ to 5f (4 J in a male), of caudal fin 6, height of body 4f to 5 in the total length. Eyes diameter of each from 4<\ to 5 or 5|- in the length of the head, 1 to \\ diameters from the end of the snout, and from 1 to If apart. Hind edge of preopercle regularly curved and with a very short but distinct lower limb. Height of opercle equals twice its greatest width ; height of sub- opercle equals half the length of its lower edge which, with its hind margin, forms a regular curve. The form of the various opercular pieces in these fishes is liable to great variation frequently due to an apparent arrest of development ; this is also seen at Howietown among examples which have had gill-fever in their infancy, and is considered to be one of its results. In one example the subopercle differs on the two sides of the same fish. The maxilla reaches to beneath the hind edge of the eye. Teeth 4 or 5 across the anterior portion of the vomer where that bone joins the palatine arch but none along its body. In a single row along the palatines and in the jaws. Fins the rayed dorsal commences slightly nearer to the end of the snout than to the base of the caudal fin, its third or fourth ray is the longest and somewhat exceeds the length of the base of the fin. Pectoral extends about half-way (in some examples more, in others less) to the base of the ventral, which latter is inserted below the centre of the rayed dorsal fin, laid flat it does not quite reach the vent. Caudal forked in the young, but becoming square with age, as seen in the trout. Scales 40 to 49 rows from the lateral-line to the base of the ventral fin : 21 to 26 rows from the hind edge of the base of the adipose dorsal fin downwards and forwards to the lateral-line ; from 185 to 235 rows pass from the back to the lateral-line. Colours greenish along the back, becoming lighter on the sides and beneath, the whole being beautifully shot with purple and gold. Numerous round or oval spots along the back becoming fewer below the lateral-line ; anteriorly from the head to the dorsal fin many coalesce. Red spots above, on, and sometimes below the lateral-line. White edges with black bases to the upper margin of the pectoral and the anterior edges of the ventral and anal. Sinuous bands of black or rings on the dorsal fin : the upper and lower edges of the caudal barred. During the breeding season, the lower surface of the body of the male is frequently of an intense velvety black. Varieties. The following refers to an example 9 inches long, which was hatched from eggs received from Lake Huron, and which lived some years in a tank at the Westminster Aquarium.

The figure is on plate cxx, fig. 2, along with one, fig. 1, raised at Howietown. Habits. Similar to our charr and, like it, appears to prefer deep water. Is generally considered to have great roving propensities and is not often found rising to the fly after having attained a pound in weight. A "conservator" writing from Shropshire to the Field, remarked that he considered it useless for turning into a running water, as it drops down stream, while it does not attain to the size of our brook-trout, and in a lake will not rise well to the fly. He thought it as bad as pike in destroying other fish, consequently he did not recommend it, although it is excellent eating, and fights well when hooked. Mr. Andrews at Guildford, states that he found that his yearlings ran from 8 oz. to 10 oz. and two-year-olds from 1 to 2 lb. each ; three-year-olds averaged 41b., and four-year-olds go 5^ lb. to 6^ lb. (Land and Water, July 22, 1882.) Breeding. The eggs as already remarked (page 105) are only about half the size of those of the brook-trout, and although in some localities it has been observed to deposit its ova earlier than the trout, it does so mostly at about the same period. " One very striking character in rearing Sal-mo fontinalis, is the remarkable difference in the growth of individuals in a single brood of fry from the same batch of ova : some at great speed outstrip their brethren in a short space of time, while the majority are probably -| less than these in size at the end of the first few months" (Carrington, Zool. 1876, p. 5112). It is by no means uncommon to find some take on cannibal propensities similar to the trout (page 94). Hybridism. In June, 1882, I received from Sir Pryse Pryse, Cardiganshire, an example 9 inches long, evidently a hybrid between this form and the brook- trout. B. x, D. 14 ( T %), P. 14, V. r. 9, 1. 8, A. 11 (f), C. 19, L. 1. 119, L. tr. 27/39. Length of head 5, of caudal fin 5^, height of body 5 in the total length. Eyes diameter of each 1/5 of the length of the head, lj diameters from the end of the snout, and If apart. Cleft of mouth deep, the maxilla reaching posteriorly to beneath the hind edge of the orbit. Hind edge of preopercle with a slight angle at its centre, also where it commences to form its lower limb, which latter is distinct. Width of opercle equal to two-thirds of its height. Height of sub- opercle at its base 2\ in that of the opercle, and having a rounded posterior margin. Teeth two at the anterior portion of the vomer where it joins the palatine arch, 6 along the body of that bone at first in alternate rows, but the last two single, the most posterior one the largest. Scales 170 rows descend from the back to the lateral-line, 19 from the hind edge of the adipose dorsal in a line downwards and forwards to the lateral-line ; 29 rows from the lateral-line to the base of the ventral fin. Fins the dorsal commences midway between the end of the snout and the base of the caudal fin ; the length of its base equals 3/4 of its height. Candal emarginate. Colours those of S. fontinalis being gray rivulated with yellowish-white and wide serpentine bauds, or forming rings round gray blotches, which have a light central spot. A few red spots along the lateral-line, but none apparent above or below it. Dorsal, caudal, and ventral fins coloured similarly to S. fontinalis but the anal with a less distinct black border at the base of its white outer edge. As food. It is excellent, the flesh may be white, perfectly pink, or of a deep red. Habitat. The fresh waters of British North America, and contiguous portions of the United States. It has, during the last twenty years, been acclimatized in this country, and thrives in most places where it has been turned out, either in Scotland, England, or Wales. In Norfolk it is said to grow twice as quickly as the brook-trout. It does well in the stock-ponds at Howietown, near Stirling, also near Guildford, and in other localities. The first plate, cxx, fig. 1, is from an example 8| inches long, from Howie- toun, and fig. 2 from an example kept for some years in a tank at the Westminster Royal Aquarium. SALMONID^. 121 Genus II Osmerus, Artedi. Branchiostegals seven or eight : pseudobranchive rudimentary. Body somewhat elongated. Cleft of mouth deep. The maxilla almost extending to beneath the hind edge of the orbit. Teeth in upper jaws smaller than those in tlie lower, in a transverse band across the vomer, some being fang-like, also strong ones along the palatine and pterygoid bones. Large fang-like teeth anteriorly on the tongue and posteriorly smaller ones. Scales of moderate size. Pyloric appendages few and short. Ova small. In Newfoundland, 0. viridescens ascends the smaller streams in thousands as the ice disappears (Saxby, Zool. 1871, p. 2553). A nearly allied genus, Thaleich- thys, exists on the Pacific coast of North America, and so full of oil are they that their common name is candle-fish, or oolachan, as after having been sun dried they can be lighted, and will burn with a spluttering flame to the end (Angler's Note-book, p. 124). An oil, reputed to be medicinal, has been introduced into this country under the head of Oolachan oil, and is scarcely distinguishable from cod-liver oil (Nature, May 12th, 1881). Geographical distribution. Atlantic coasts of temperate and northern portions of Europe and North America, ascending rivers to spawn and frequently becoming resident there. One species from California. Its growth is said to be frequently much retarded when passing from a marine to a fresh-water existence, in some parts of northern Europe it is acclimatized where there is no available outlet to the ocean.

Ventrals inserted below the anterior rays of the dorsal fin. Caudal forked. Scales cycloid and deciduous ; 6 rows between the lateral-line and the base of the ventral fin. Lateral-line indistinct after the first few scales. Ccecal pylori seven very short ones, scarcely perceptible except after the intestines have been distended. Colours of a light olive-green, superiorly, becoming silvery shot with purple on the sides and beneath. A wide silvery band passes along each side, numerous fine black dots are present on the head, back, dorsal and caudal fins more especially in large examples. Caudal dark edged. Eyes silvery. Varieties Linnaeus considered that in the Baltic there were two forms, one termed nors possessed a foul odour, which in the early spring when the peasants come to buy it, fills all the streets of Upsal with the smell ; adding that at this period agues prevail there. Valenciennes considered this to be 0. spirinchus, Pallas, having a shorter body than the common form, and that it must have been from one of this variety that Bloch figured his fish in plate xxviii. Bloch erroneously believed that the same cause occasioned like results in London. Names. Smelt is said to be derived from its possessing a peculiar odour : resembling cucumbers, violets, or rushes. Jonston imagiued that the term smelt was used in the sense of smelting metals, and derived from the transparent appearance of the fish, as if it were going to melt away. Sir J. Browne termed them spirinches, and a small one a priame. The Germans, owing to its aroma, term it the "stinkfisch," and Linnaaus observes that the odour from some, warrants the German epithet : Taylor (Hardw. Sc. Gossip) has known the smelts to come up in such numbers that it was easy to detect the peculiar cucumber smell which distinguishes them, by walking along the river side. Sparling is a corruption of the French term " Eperlan," or else the two words are of a similar origin. Sprot is termed by Palsgrave to be a " sprat " or a " smelt." Spurring, North- umberland : Prim is the fry (East). Sibbald (Scotia, Illustrata) has an Apua vera, which he termed Sparling, Apua or Aphia were names which used to be applied to a goby. Be spiering or spierling, Dutch. Eperlan, French. Habits. A gregarious and voracious species, remaining with us throughout the year, and passing a portion of each season in fresh, and the remainder, as a rule, in salt water, but irregular in its migrations, continuing in some rivers five or six months, in others hardly as many weeks. It is generally found in rivers or fresh waters, from August until May. In the Thames it rarely ascends above Woolwich, but Buckland in March, 1868, received three live ones captured nearly as high as Teddington, while others were taken near Kew Bridge. This year (1882) some were present at the end of September, and had selected their spawning quarters in the tideway opposite Chiswick Mill, and Strand-on-the- Green. One fully 9 inches long was captured while bleak fishing at Wooden-bridge- creek, Hammersmith. It drives the dace before it, these latter fish ascending to Richmond, Isleworth, &c. (Field). Lubbock observed the same migrations of roach and dace in Norfolk, fleeing from the smelts,* which regularly ascend the * M. de la Blanchere observes thai the odour of the smelt drives other fish away, and thus protects it lroiu its enemies. SALMONID^E. 123 rivers in spring to spawn, and only stops its upward course at some insurmount- able barrier. It appears to be particularly partial to small fish and shrimps. In some parts of Sweden, Nilsson found that they remained in lakes which possess sandy bottoms all the year round : in the spring they migrate to the shallow portions and ascend rivers. Colonel Meynell, of Yarm, in Yorkshire, kept these fish for four years in a fresh- water pond, which had no communication with the sea ; and Yarrell states that they continued to thrive and propagated abundantly. The pond being frozen over did not affect them, and they did not lose either flavour or quality (Wern. Mem. December 17th, 1825). Mr. Egerton acclimatized these fish in fresh water, in a lake at Roselherne Manor, Knutsford, Cheshire. Many are kept alive in tanks in the Norwich fish-market until required for use (Southwell). Mr. W. Wanklv of Grange-over- Sands, Lancashire, sent an account of these fish to Land and Water, and observed he was much struck with the very rapid growth of the sparling from October to March in October ten or twelve together weighed no more than 1 lb., in March the fish were 4 oz. to 6 oz. each, and occasionally one or more in a take weighed close on 8 oz. He opened a sparling as soon as it was taken out of the net, and found six, seven, and eight herring fry : next he tried the experiment of thus opening one or two alive, and taking others home intact, and always found nothing but digested food when the latter were gutted to be cooked. Opening some of the herring fry taken out of the fresh-taken sparling, i.e., just out of the water, he repeatedly found in the herring fry small shrimps, most neatly stowed away. The gastric juice or fluid of the sparling was so acrid, that when he wiped his hands on his pocket- handkerchief and then used the handkerchief to blow his nose, both his nostrils and lips were inflamed and irritated, and more than once his tongue swelled in an extraordinary manner. The sparling were following and feeding on the herring fry, or herring ewes, as they are called there. The sparling are very uncertain and apparently fickle in their visits to their supposed haunts i.e., in holes near rocks, where fresh-water streams mingle with tidal water. One day 201b. or 30 lb. may be taken ; then for a week or ten days only an odd fish or two will be got; then a week of good takes. They are easily driven away, for on one occasion some men left a boat anchored in a hole to reserve the right of first draw. Whilst that boat remained there no sparling rested in the hole, but when it was removed they returned to their haunt. Means of capture. In Norfolk the fishery commences in March, and continues until the middle of April, during which period the fish are full of roe. The smelter, says Lubbock, hour after hour does he persevere, moored exactly in the same spot with a torch attached to the side of his broad flat-bottomed boat (for this is a nocturnal occupation) in flinging his immense casting net, dropping the near side of it at each throw, within three inches of the torch. One fortunate cast, if smelts sell well, may recompense him for hours of fatigue, wet, and cold : and he waits like the losing gambler for the lucky throw which is to brighten his fortune. The smelts captured are kept alive in a tank. They are likewise taken in the estuary of the Ouse and in Brejdon by means of stake nets. It appears to be partial to sandy shores, as off the Lincolnshire coast, while the different schools appear to consist of fish much of one size. At the outlets of many of our larger rivers were or are smelt fisheries which must have been carried on for long periods, because we find a mesh for the purpose of taking smelts legalized at the time of Queen Elizabeth. They may be caught with a paternoster line and No. 8 or 9 hooks, floats may or may not be used, shrimps either fresh or boiled, gentles, a red worm, or slices of fish form good baits. Bread crumbs have been recommended as ground bait Early moimings and late of evenings have been considered the best times for this fishing. In the Solway Firth the best fishing season is in September, but they disappear the next month until March and April when they ascend to spawn. Breeding. Ova small, of a yellow colour, while the females are said to preponderate largely in numbers over the males. On January 13th, 1882, the season being very mild, I obtained smelts with the ova half developed. They 124 PHYSOSTOMI. generally deposit their spawn about March or April, and mostly near the high water spring-tide mark, subsequent to which they descend to the sea. In March, according to Parnell, they ascend the Forth in large shoals, and shed their spawn in immense quantities about two miles below Stirling Bridge, where at that time every stone, plank, and post appear to be covered with their yellowish-coloured ova. The fry are found about 3 inches long, swimming near the surface in shoals in the rivers in the month of August, ascending and descending with the tide (Yarrell). In America, at Maryland, the attempt to artificially propagate a species of this genus in 1877 proved unsuccessful. As food. The smelt is justly held in great estimation for the table, but after spawning becomes insipid. It used to be split and dried and was thus considered to add a particular relish to the morning dram of spirits. Spring fishing for smelts is said to be inimical to smolts in Solway Firth, while in autumn the nets kill the parent fish. It is said by the French to be a good bait for eels : while the picked dog fish, Acanthias vulgaris, destroy large numbers of them in estuaries. Habitat. Coasts of Northern and Central Europe (probably excluding Iceland), and entering fresh waters, found in all the larger lakes of Finland, as well as along the sea shore (Malm). Along the Atlantic coast of France, abounding in the summer, and in the Seine as high as Rouen. Banffshire, rare (Edward). St. Andrews, not uncommon, large numbers being caught in the Tay (Mcintosh). In the Firth of Forth, in the neighbourhood of Alloa, it is taken in great numbers, especially towards the fall of the year. Those captured from November till January seldom exceed 6 inches in length, but after the end of March the larger ones appear and the smaller ones take their departure (Parnell). Some of the rivers of East Anglia abound in these most beautiful and delicious fish, which are resident and common in the estuaries of the Tees and of the Humber. Also in the Ouse and the Humber from Nabura Loch to Spurn Point, and occurs a considerable distance up the Tees (Yorkshire Vertebrata). There is a smelt fishery at Boston in Lincolnshire, from September until May, the fish being full of ova in April. It seems to be absent along our south coast from Dover to Land's End. Dr. Norman, of Yarmouth, in 1881, mentions in Land and Water a fine specimen he saw in Mrs. French's shop window at Yarmouth, scaling over seven ounces. Their cucumber-like smell when first caught is very perceptible. Then they are indeed a treat ; but, in a few hours after, become comparatively insipid. Found in the estuaries of the Thames and Medway, in which latter river Pennant observed it never enters so long as snow water is present. Parfitt (Fauna of Devon, p. 19) observes of this fish, "taken in the Exe : Eoss, MSS.,i, p. 55." Having been shown the MSS. by Mr. D'Urban at the Albert Institute, Exeter, I find that it is the sand smelt, or Atherine, which Mr. Ross referred to. It has been asserted that this fish has been captured as far south as Swansea, but the statement is doubted by Dillwyn, who never found it there. Examples from Conway are in the British Museum. Along the west coast this fish is taken in the Dee and in the Mersey, while at Ulverstone they are found heavy with spawn about the middle of March, the fishery being concluded by the middle of April. There are also smelt fisheries in the estuaries of many of the rivers which enter the Solway, where they arrive in March or April to spawn, they are very small in June and July, but at their prime in September. They do not appear to ascend above brackish w T ater in order to deposit their ova. In Ireland, Rutty, in his natural history of the county of Dublin, and Smith in that of Cot'k, mentions the capture of the smelt, and Templeton (Mag. Nat. Hist. 1837 (2), i, p. 411) asserts that it is sometimes taken on the coast in considerable abundance, but often several years intervene during which they are scarcely met with ; Thompson suggests that these authors allude to the Atherine or sand smelt (i, p. 225), as he cannot find any authentic record of the true smelt having been captured in Ireland. It attains to 10 or 12 inches in length. Pennant alludes to one of 13 inches which weighed 1^ lb. The example figured is 10 2 inches in length. SALMONID^, 125 Genus III Coregonds, Artedi. Argyrosomus, Agassiz (lower jaw the longer). Branchiostegals seven to ten : pseudobranchiai well developed. Body somewhat elongated. Cleft of mouth shallow : maxilla deep, and posteriorly not extending to behind the orbits. Teeth, when present, minute and deciduous. First dorsal fin with a moderate number of rays, the second adipose. Caudal forked. Scales of moderate size'. Air-bladder large. Pyloric appendages numerous. Ova small. Some authors have believed that the vendace, Coregonus vandesius, was introduced into Lochmaben, Dumfriesshire, from the continent of Europe, by or for the unfortunate Mary Queen of Scots. As the species has not been recognized on continental Europe, is difficult to transport, while it is not restricted to one Scottish loch, this tradition appears to rest on an uncertain foundation. In aquaria a very little matter affects them, a trifling variation of temperature, a little impurity or a difference between the oxygenating surfaces of two tanks, Lloyd proved were matters of life or death. It has been questioned by some excellent authorities whether the species of this genus may not have been unduly multiplied, and M. de la Blanchere (Diet, des Peches) observed that after a special study made at the Imperial establishment at Huningen, whei'e he had fishes of all ages under observation, he had come to the conclusion that either the genus Coregonus ought to be composed of many distinct species, these distinctions being based upon fugitive and little marked characters : or else, that a single species is present endowed with great variability.* Geographical distribution. Mostly found in lakes, a few periodically migrating to the sea, in the northern portions of temperate Europe, Asia, and North America : while some appear to be marine. There are numerous species, several being found living in a single lake. In North America, under the term of " white fish," they are captured throughout the fresh waters. Dr. J. Davy observed that the vendace and skelley are rarely taken by anglers, or any way except by the net, and are of comparatively little value. It cannot be supposed that man ever took the trouble to place the skelley in a tarn such as the Red-Tarn, situated under the brow of Helvellyn, many hundred feet above Ullswater, and so difficult of access. Much the same reflection presents itself as regards the vendace in Derwentwater and Bassenthwaite Lake, taking into account the distance of these lakes from Loch Maben. Synopsis of Species. 1.

Scales about 34 anterior to the base of the rayed dorsal fin ; 7g between the lateral-line and base of the ventral, where there is an elongated scale. Intestines stomach siphonal with about 200 short ccecal appendages. Colours gray along the back becoming silvery on the sides and beneath. Snout black. Fins yellow, upper edge of dorsal black ; tip of adipose dorsal and caudal gray, a dark mark across ventral, and a slight band along the anal. Varieties. Valenciennes observes that two varieties exist : the one blackish with a shorter snout from Lake Malarn ; the other paler in colour, having a longer snout, found in Lake Wenern, and termed Nabb-sik. Names. Houting or Hautin, from the Dutch, a probable corruption, according to Valenciennes, from Whiting. Habits. Mostly marine, but enters fresh waters. It seems to do better in a fresh water than in a marine aquarium. Habitat. Coasts of Northern Europe, entering fresh waters in Holland, Germany, and Denmark. I received the first recorded British example April 17th, 1877, from Lincolnshire ; in March, 1880, the late Mr. Buckland sent me one captured near Chichester. February, 1881, I obtained a third from the mouth of the Medway, taken from among some smelts. Rutty (Nat. Hist. Co. Dublin, 1772, i, p. 365) observed, " Thymallus, the Grayling or Umber. With us it is a sea fish, and less than Willughby's, which is a river fish." He may have been referring to Coregonus oxyrhynchus. The figure is from the Lincolnshire example, 7 inches long, already referred to, but the fish attains to more than twice this length. * Malm considers Coregonus marmna, Nilsson, and C.

Snout truncated : the upper jaw somewhat longer than the lower ; the maxilla reaches to beneath the first third of the orbit and is slightly longer than the diameter of the eye, while the length of the mandible is 2/5 of that of the head. Nostrils close together, midway between the eye and the end of the snout. As, in some examples, there is a slight depression at the nape it gives the appearance as if the back behind the head were somewhat arched. Teeth absent or very minute. Fins the first dorsal commences midway between the end of the snout and the termination of the base of the adipose fin, it is two- thirds to three-fourths as high as the body beneath it Pectoral inserted below the middle of the depth of the side, and is as long as the head excluding the snout. Ventral below the middle of the first dorsal, and midway between the posterior extremity of the head and the commencement of the base of the anal fin. Caudal deeply forked. Intestines ccecal appendages short and numerous. Scales 7 to 8 rows between the lateral-line and base of the ventral fin. Colours silvery lightest on the sides and beneath, fins dark gray, almost black, externally. Varieties Parnell considered that two species were found in Loch Lomond, the first being Lacepede's fish, but as a Coregonus clupeoides, Pallas, existed, he termed the commonest C. Cepedei and the smaller headed one C microcepkalus, subsequently he informed Yarrell that he had received intermediate forms. I possess an example from Haweswater in which the middle of the dorsal fin is not only deficient but the back is regularly scaled between the end of the base of the seventh ray and the last three, the four or five missing ones having evidently not been developed due probably to some embryonic injury. Names. The Welsh name Gwyniad, or white fish, is derived from Gwyn, " white." In Ullswater it is known as the Schelly, a term which is said to refer to its scales. Fresh-water herring. Habits. Similar to those of the other fresh- water forms, and as a rule refrain- ing from entering: running water or coming to the surface at mid-day. The late 1 ll j 1 J TT Professor Rolleston gave me some examples which he collected at Haweswater, and informed me that in the early spring some came to the sui'face with the stomach everted, due to expansion of the air-bladder. We examined one and found the pneumatic tube to be pervious. Means of capture. Netting. In Loch Lomond the fishing lasts from March until September, the fish being considered in their prime during August and September. Parnell observes that although they are taken by means of drag nets, occasional instances have occurred in which a few have been secured by the artificial fly, but they had never been known to touch a minnow or other bait. 128 PHYSOSTOMI. Breeding. December (Pennant). As food. Dry and insipid. It soon decomposes. Habitat. Loch Lomond, Ullswater, Haweswater, and large lakes in Cumberland, the Eed Tarn, a small piece of water upwards of 2600 feet above the sea, near the summit of Helvellyn. Conningham mere, Lancashire ; Pemble mere, near Chester ; Lyntegid, near Bala, in Merionethshire ; and an instance has been recorded of its straying six miles down the Dee as far as Llandrillo. The example figured was from Bala lake, and I am indebted for it to Spencer Walpole, Esq. This fish attains to 3 or 4 lb. weight (Pennant), and has been recorded up to 16 inches in length. 3.

Fins the first dorsal commences nearly midway between the end of the snout and the posterior end of the base of the adipose dorsal fin ; it is four-fifths the height of the body below it. Ventrals inserted on a line below the anterior portion of the first dorsal fin and midway between the hind edge of the opercle and the commencement of the anal fin. Ccecal appendages numerous. Scales 7 rows between the lateral-line and the insertion of the ventral fin. Colours greenish blue along the back and upper half of the body, silvery dashed with gold along the sides and beneath. Fins rather dark. Sir W. Jardine observes that where the bottom is mossy they are of a darker tint above and incline more to yellowish brown on the under parts. Varieties. In those from the Castle Loch the lateral-line is said to be mesial, while in such as come from Mill Loch it is nearer the dorsal profile, the latter being likewise thicker and possessing longer heads. Names. Pennant suggests the term Vendace has been derived from the French Vendoise, "a dace," which it may have appeared to resemble to the Frenchified Scotch Court which attended Queen Mary in her forced retirement when it was said to have been introduced. Habits. A gregarious fresh-water fish which swims in large shoals retiring to the depths of the lakes as the warm weather sets in. It has been said that the sexes keep apart, but in a draught made in October nine were females and six males, which would tend to show that they reside together. As Knox conveyed some of these fish alive in a bucket of water to the village, it shows they do not, as has been asserted, die immediately on being taken out of the lake. Knox (Ann. Nat. SALMONID^E. 129 Hist. (2), xv, 1855, p. 57), found the stomach of some he examined distended with thousands of Entomostraca. Jardino observed the same food in those he dissected. Means of capture. Netting. Breeding. Generally, but not invariably, about the middle of November. Knox examined 22 females captured the middle of December, in 19 the ovaries were small, very soft, and the ova mere points, while the fish were in good con- dition : in the other three the ova were large and the parents about to spawn : in two males the milts were progressing in size, but not much enlarged. As food. It is much esteemed locally, being considered a great delicacy for the table, enhanced possibly by the difficulty in procuring it. Habitat. In two of the system of lakes near Lochmaben, Dumfriesshire, namely, the Castle Loch, so termed from the ruined castle of Brus, on its banks : and the Mill Loch ; the latter being deeper but less extensive.

Thompson observes that he has seen individuals with the upper rather exceeding the lower jaw, others with the lower slightly projecting beyond the upper, and the difference was not sexual. The posterior extremity of the maxilla reaches to beneath the first third of the eye. Teeth if present very minute. Fins the first dorsal commences midway between the end of the snout and the hind edge of the base of the anal fin, it is five-sixths the height of the body beneath it : ventral inserted below the middle of the first dorsal fin, and midway between the hind edge of the head and the middle of the base of the anal fin. Coecal appendages numerous. Scales nine rows between the lateral-line and the inser- tion of the ventral fin. Colours superiorly bluish along its upper third, silvery on the sides and beneath. Dorsal, caudal, and anal fins darkest externally. Varieties. The pollan of Lough Erne, was observed by Yarrell to be com- paratively rather deeper than those from Lough Neagh. Mr. Ffeirnell produced specimens of the pollan taken in November, 1881, in Lough Neagh, and some from Killarney, taken May 8th, and pointed out the difference in the shape of the head and gill-covers in the specimens from the two localities (Dublin Nat. Hist. Soc. April, 1852). Names. Pollan, from a local Irish term. Thompson obtained two examples, 4| and 4f in. long, from the Shannon at Killaloe where it was termed a Cunn, this form being reputed to descend the river with the eels during the winter and to refuse all bait. He first proposed to term it Goregonus elegans. Habits. This fish approaches the shore in large shoals, not only during spring and summer but late into the autumn. It dies soon after being removed from the water. In Lough Neagh, where it is a permanent resident, it is not generally diffused but approaches the shores at some particular spot, to which it returns again and again. A correspondent of the Field (Jan. 29th, 1881) observes respecting this fish in 9 130 PHYSOSTOMI. Lough Derg : During the last two seasons I have occasionally come across instances of the fresh-water herring or " pollen " a fish that little seems to be known about. Those that I have seen I have always found floating in very deep water about the centre of the lake in a half dead condition ; and, though I have been fishing the lake for twenty years, I never before came across one ; but I have been told that at times they have been taken in great numbers in nets. I never heard of one having been taken on a hook, nor do I know on what they feed. Several examples of this fish have been similarly obtained in different years. Thompson examined the stomach of six pollans in June, 1836, and " found them all filled with food consisting chiefly of mature individuals of Gammarus aquations, and the larva? of various aquatic insects : some shells of the genus Pisidinm, one of the fry of the three-spined stickleback (Gasterosteus), and a few fragments of stone." In the stomach of one captured at Lough Neagh in July, there were not less than a hundred examples of Mi/sis and a single Isimneus pereger. Means of capture. Netted usually in an afternoon, then packed in boxes and transmitted by rail and steamer to Liverpool, Manchester, and other large towns. Has occasionally been taken with the artificial fly. The pollan, observes Thompson, approaches the shore in large shoals, not only during spring and summer, but when the autumn is far advanced. The usual time for fishing for it is in the afternoon, the boats returning the same evening. On the days of the 23rd, 24th, and 25th of September, 1834, they were caught plentifully from the shore. A shoi't time previously 17,220 fish were taken at one draught, selling at 3s 4cZ the hundred (123), producing 23. 6s 8d. In a letter from Francis Nevil, Esq., to the Lord Bishop of Clogher, dated February 12th, 1712, writing respecting Lough Neagh, he remarks that among other fish it abounds in pollans. "The English call them fresh-water herrings, for want of another name ; for pollan is an Irish name. They catch them in summer with seines as they do herrings, and they are a great relief to the poor, being very cheap ; they ai*e much in shape and bigness like to the largest smelts, full of very large bright scales, and pleasant meat, being eat fresh. They were supposed to be a peculiar fish to that lake ; but since I came here I find Lough Earne has the same sort, but not in so great plenty. They are generally caught here in the eel-nets, running to the sea." Breeding. They spawn in November and December on a hard or rocky bottom, the ova are from ^o to | of an inch in diameter. Thompson found 6156 ova in an example llf in. long taken in Lough Neagh, November 28th, 1839. As food. It is not held in any great estimation as it does not keep well, still if fresh it is thought by some to be a well-flavoured fish. They used to be taken in great quantities to Belfast ; large numbers are now exported to England. Habitat. Ireland in Loughs Neagh, Eai-ne, and Derg, also in Lough Corrib and in the Shannon. It attains the length of about 12 or 13 in., and its usual weight is about 6 oz. This fish was first alluded to in Harris's History of the County of Down, 1744; it is also mentioned under the name of GoasJce, in Sir Henry Pier's Description of the County of Westmeath, 1744, wherein it is said to be peculiar to Loughs Tron and Direvragh. Though permanently resident in Lough Neagh, it is not generally diffused there, and Thompson observes that it rarely occurs between the Rivers Mayola and Toone : while from the six-mile-water to Shanes Castle is so favourite a resort, that a few houses which formerly stood near the latter locality, were dignified with the name of Pollans Town. The common eel is stated by a fisher- man at Lough Neagh to live chiefly upon the pollan, and he frequently knew it destroy these fish when in the nets, and also injure the nets. The largest example Thompson heard of was said to have weighed 2-J- lb., but the largest he actually saw were 13 inches long. salmonim:. i3i Genus IV. Thymallus, Guvier.

The first dorsal fin commences midway between the end of the snout and on a line above the front edge of the anal fin, the height of its rays being about two-thirds of that of the body below it. Pectoral inserted in the lower fourth of the height, and as long as the head excluding the snout. Ventrals situated beneath the middle of the rayed dorsal fin, and comparatively small, terminating on a line below the hind edge of the adipose dorsal. Caudal forked. Scales in regular rows, some small ones being present over the basal portion of the caudal fin. The chest, or that portion of it as far as the pectoral fin, may be entirely destitute of scales or else scaled. In the example figured there were twenty-two rather short ccecal appendages. "Walls of the stomach thickened. Colours these during life are beautifully changeable ; head of a bluish purple and a golden tinge along the back, while the horizontal lines along the body are dark, and each of the scales has a golden tinge. Dorsal fins with purplish bands and ocelli which have a purplish red centre, and there are likewise some purplish streaks along the courses of the rays, while the outer edge is likewise purplish. Occasionally there are some black spots on the fins, also scattered over the body. The brighter colours decrease with age, and gray lines show themselves along each row of scales ; while the young have transverse bars or bands. Names. Thymallus was given to this fish by Ausonius, from the fancied resemblance of its odour to that of the water thyme, upon which it was supposed to feed, an odour which those of the present day fail to detect ; but Mr. Pennell considers that he can observe some likeness in its smell when first captured to that of the cucumber. Some who imagine they are able to recognize this odour have suggested that the varying nature of its food may cause the grayling to occasionally possess a strong smell which at other times almost or quite disappears. " Grayling " is said to be a corruption of Gray lines, referring to the longitudinal lines along its gray body. Oumer, Northumberland. Shutts, or Shot, young in the Teme. While St. Ambrose of Milan is recorded to have termed it the " flower of fishes." Aubrey in his MS. says that in his days the umber was caught in the Madder, between Wilton and Salisbury, &c. " This kind of fish (he remarks) is found in no other river in England except the Humber in Yorkshire. From that river, therefore, I conclude it takes its name of umber " (Maton, Nat. Hist, of Wilts). Salviani in the sixteenth century observed, that being a swift swimmer it disappears like a shadow, from whence it derived its name umbra. Cotton, however, says this name is due to the black or shadowy spots on his belly, and the black colour of his head when out of season. One-year- old fish are in some places known as pinks, at about ^lb. weight shot or shut, i.e. prior to breeding. Be Vlagzalm, Dutch. Ombre, French. This fish is another whose introduction has been ascribed to the monks, and many of the local grayling fisheries are found in the vicinity of where monasteries formerly stood. But it would be difficult to convey this fish from the continent with the means then at their disposal; while in Kent, Dorsetshire, Devonshire, and Cornwall, where there were many monasteries, grayling are not found. Habits. Although present in many of our rivers, and in some abundantly, the grayling is certainly a local fish, while at times it appears to be gregarious, showing a tendency to congregate in small shoals, which generally drop down stream. In this country it would appear to be a strictly fluviatile fresh- water fish in its habits, never migrating to the sea ; but in Scandinavia it is found in lakes also in the North Sea, Cattegat, and Baltic. Sir Humphrey Davy tried it in brackish water but without success. It prefers clear streams, in which there are a succession of pools and shallows, with sandy, gravelly, or loamy beds, rocky or stony bottoms being unsuitable. The larger ones seem to resort more to the deeper and quiet spots, the moderately-sized and small ones to the shallows, taking their post behind a rock or a bunch of weeds. Although clear streams are to be preferred, still a moderate temperature of the water seems to be of more consequence, as too much cold or too much heat are asserted to be equally fatal to it. It is not every river that appears suited for the grayling, thus the attempts to acclimatize it in the Thames do not appear, so far, to have been a success. It lives SALM0NIM3. 133 somewhat deeper in the water than the trout, and although in some streams the two forms reside together in not unfriendly terms where food is abundant, such is not invariably the case, as in some localities it is popularly said to bully the trout : it may be that being to a great extent a ground feeder, while the trout is breeding it helps itself to the eggs from the trout's redds. It is not of a roving disposition and generally limits its range to within a few miles : it cannot spring out of the water like the trout, consequently is unable to surmount barriers, but its large back fin, aided by its well-developed air-bladder, would seem to show that its formation is that best adapted for rapidly rising or sinking in the water. In spring months it returns to deeper water and seems alrroft. to cease to feed, possibly due to the nearness of its breeding season. It has been found to live in newly-made ponds, constructed in hard soil, where, however, it is said not to breed, but more investigation is required on this question, as the same was believed of the trout (see page 105) : old and muddy ponds are not suited for their existence, for there they rapidly succumb. It eats insects and their larva?, small molluscous shell-fish as Physa and Neritina, also Crustacea, Migrations. I have already observed that occasionally these fish congregate in shoals and generally drop down stream, in fact, it used to be considered that they never headed up. Mr. Francis Francis (Field, May 28th, 1881) observed, upon one being taken in the Anton, continuing, only a few years ago there were none much above the sheep's bridge at Houghton. This year there are many in the Machine Barn shallow, two miles up ; but that they should have headed up something like a distance of ten miles, and out of the Test into another stream, is astonishing. Mr. Brotherton, of Kelso, observes that this fish was introduced there by the late Marquis of Lothian, and it appears to be particularly suitable to its habits, as it is increasing rapidly, and also spreading down into the Tweed. Breeding. Generally spawns on the shallows in April or May, or even earlier. On February 26th, 1881, Mr. Bowie Evans sent me two examples from Hereford- shire, and I found the ova almost ready for extrusion (the preceding winter had been a very mild one). The ova are somewhat smaller than those of the trout, and may be white, opalescent, cornelian colour, or even deep orange : they are deposited on the gravel near the tails of shallows, and not in a nest or redd like the salmon, trout, or charr. Neither do these fish attempt to pass up to the heads of streams for breeding purposes, but choose shallow localities near where they usually reside, and where females may be seen waited on by two or even three males. The ova are much more delicate than those of the trout, or charr, dying on the least provocation, and it has been remarked in Herefordshire that should a severe frost occur during their spawning season, the succeeding year's supply of young fish appears to be deleteriously affected. The body of the embryo is visible in the egg on the ninth day, and usually hatches from about the twelfth to the fourteenth day. Due to this rapid development, it becomes almost impossible to transmit eyed grayling ova to any distance, as scarcely three days elapses between the appearance of the eyes of the embryo and the eggs hatching. About the end of July or commencement of August the fry are about four or five inches long. In aquaria it has been observed that young salmon or trout will readily eat young grayling. Means of capture. Netting similarly to that employed for trout, but generally this fish is taken by angling. Although, as has been frequently observed, this fish is to a certain extent fit for eating all the year round, it is most justly protected throughout the spawning months, while during October and November it is in its prime for the table. In the Test, although the Houghton Club used to open this fishing from June 1st, the fish were generally in poor condition, but ready to take almost any fly which was offered : but in July the case became different, the fish were in good condition and much more difficult to please. But it is generally considered that September and October are the two best months for the flyfisher, still in November they will take a fly or a bait, more especially in the middle of the day, and even with a shining sun. The grayling is not quite so shy as the trout nor so game when hooked : a shorter line may be employed, and fishing down stream is mostly adopted. It will rise several times in succession 134 PHYSOSTOMI. at the same fly, and, if not touched by the hook, attempts at its capture may be continued. If a rise occurs, the fisherman should strike gently, play his fish quietly, and land it with a net, because its mouth is tender and readily gives way. The flies employed are much the same as those for trout, but smaller as a rule, although they will not always refuse the May fly. The smaller fish are generally taken on the shallows, and with the fly which is usually refused by the larger grayling. The larger fish frequent the deeper pools or sluggish portions of the stream, sometimes selecting the vicinity of the roots of a tree which juts into the water, sometimes being more in mid-water. What is termed a grasshopper, which looks like a nondescript caterpillar, with the point of the hook covered by gentles, is considered to be the best bait in the Shropshire and Herefordshire districts, and commencing to be employed about September and the two following months on warm days succeeding frosty nights. Having a quill float and a stiffish rod it is worked on the sinking and drawing plan, having sank to the bottom it is raised about a foot and allowed to sink again, while the stream should suffice to carry it on a little way with each successive jerk. In Derbyshire streams it is said not to be much of a success. The principal ground baits are fishing with gentles, worms are likewise employed. The grayling occasionally may be taken with the minnow mostly in clear or else very slightly coloured water. Life history. These fish are rapid growers, attaining to four or five inches in length in a few months. Sir H. Davy (Salmonia, p. 188) believed that such as were hatched in May or June become nine or ten inches in length by September, and weigh from five to eight ounces. Diseases. It was formerly abundant in the Aire above Bingley, but was entirely destroyed in 1824 by the bursting of a peat bog, and subsequent attempts at reproduction have proved ineffectual (Yorkshire Vertebrata, p. 129). Mr. Francis Francis (Field, December 31st, 1881) observed that, although there are no very violent pollutions in the Wye above Rowsley, yet both trout and grayling have perished from fungoid there in myriads, indeed some years ago Rowsley Meadows were pretty nearly cleared out of grayling by it. This fungoid disease, Saprolegnia ferax, has been found affecting these fish in common with trout and other forms. As food. Its flesh is white, delicate, and in the best condition about October and November, when the trout are mostly out of season : in fact it is not until August that it is generally esteemed worth cooking, while it should be dressed as soon as pi^acticable after removal from the water. It is generally boiled : large ones are said to be improved by crimping. Uses. It is stated that in Lapland a substitute for rennet used to be obtained by pressure from the entrails of the grayling, with which they converted the milk of the reindeer into cheese. Eabitat. Lapland, Scandinavia, Germany, Britain, France, Switzerland, Italy, and Hungary. Were introduced* into tho Upper Clyde in 1855, from three dozen fish brought from Rowsley, Derbyshire, and are said to thrive well. They have likewise been introduced in the Teviot and Tweed and are also thriving (Brotherton). In Cum- berland in the Eden and in the Esk (Heysham) while two examples from the Tyne, presented by Mr. Knight, are in the British Museum. In varying abundance in the middle waters of the Wharpe, Washburn, Nidd, Ure, and Swale ;f also in the Cover, Wiske, and Colbeck, the Rye and other tributaries of the Upper Derwent and the Scalby Back near Scarborough. In a limited amount in the Tees, and has been introduced into the Esk. Formerly common in the Ribble and Hoddei', their extreme scarcity if not extinction being ascribed to the great increase of salmon (Yorkshire Vertebrata). In Lancashire, the Ribble, in Derby- shire and Staffordshire, the Dove, the Wye, the Trent, the Blithe and the Hodder. * Orkneys, according to Low, where he stated it to be common. f A correspondent in the Field (Nov. 25th, 1882) denies the present existence of this fish in the Swale ; the British Museum possesses lour reputed specimeus from that river, received withParnell's collection. SALMONID^E. 135 in Shropshire, the Severn, the Teme, the Clun, the Corve and the Onny. In Merionethshire, the Dee and the Vyrmoz. In Herefordshire, the Arrow, the Lug, the Dove, the Wye, and the Irwin contain them. In Hampshire and Wiltshire in the Test, having been introdnced from the Avon (Davy), also present in the Itchen and both the Avons. The Swansea Guide states this fish to be taken in the neighbourhood, but this Dillwyn doubts the correctness of. In 1863, 1470 fry were placed in the Lea rather more than three miles beyond Hertford (Wix). In May, 1866, it was introduced into the Lornan at Tiverton (Partitt). It appears also to have been introduced into the Thames. Ireland. Rutty, 1772, observes " Thymallus, the Grayling or Umber. With us it is a sea fish, and less than Willughby's, which is a river fish." It seems to me probable that he may refer to Coregonus oxyrhynchus as I received the example figured, as a grayling. Brown two years after Rutty (1771) enumerates the grayling : but Thompson observes that " the parr has been sent to me from the south of Ireland under the name of grayling. Perhaps this name, as applied to the parr, may be a corruption of the word graveling, which is generally applied to that fish in the southern counties." For the example figured, which is a male 15| inches in length, I am indebted to the Earl of Ducie, who captured it in the Test, April 30th, 1879. In the club fishing waters in that river at Stockbridge and Houghton, a memorandum of the largest grayling captured every year from 1831 to 1874 was kept ; it shows the annual variation to be between 3j lb. to 31b. 11 oz. Pennant records one of 4 lb. 6 oz. from the Tame at Ludlow. Yarrell mentions another one of 4} lb. from the Test, and Daniel one of 5 lb. from near Shrewsbury. In Lapland it is said to reach to 8 or 9 lb. weight. Stomach and ccecal appendages of Coregonus oxyrhynchus. 136 PHYSOSTOMI. Genus V. Argentina, Artedi. Situs, Gill. (Scales spiny.') Branchiostegals six : pseudobranchim well developed. Cleft of mouth small, the upper jaw rather short, not extending to below the orbit, formed by short premaxil- laries anteriorly and the maxillaries laterally. Eye large. No teeth in the jaivs, minute ones across head of vomer and anterior portion of palatines : a row of curved teeth on the anterior portion of the tongue (except in A. lioglossa).

Stomach large, with a cul-de-sac: pyloric appendages short, and in small or moderate numbers. Ova small, falling into the cavity of the abdomen before extrusion. Air-bladder small, and (according to Cuvier) destitute of a pneumatic duct. Dr. Giinther observes (Introd. Study of Fish. p. 650) that both "Argentina silus and A. Hebridica have been found occasionally on the North British coasts." I have been unable to ascertain any record of the former, except an example of A. sphyrcena, thus termed by Edward, but which he considered identical with my figured species : while A. sphyrcena and A. Hebridica are two names for the same species. The difference between the two species is as follows : Argentina silus, D. 11-12 | 0, P. 17-18, V. 12-13, A. 14, L. 1. 60-65, Vert. 65.

Length of head 4 to 4f , of caudal fin 7|, height of body 5f to 8 in the total length, varying according to age, being deepest in adults. Eyes with moderately wide adipose lids, the anterior lid overlapping the posterior above the centre SALMONIM:. 137 of the upper edge of the orbit, diameter 3 to 3 in the length of the head, 1 diameter from the end of the snout, and also apart. The shape of the fish is peculiar, the back, sides, and abdominal surfaces being flattened so as to give it a general tetragonal appearance, while keeled ridges divide the various surfaces one from the other. These four surfaces are further subdivided by other parallel ridges, one of which is a short distance internal to the superior orbito-caudal ridge, and another superior to the pectoral ridge. Irrespective of these, a short ridge passes from the lower edge of the base of the pectoral fin to the anal fin. Upper jaw slightly the longer : the posterior extremity of the maxilla scarcely reaches more than two-thirds of the distance to beneath the front edge of the eye. Snout depressed and somewhat pointed : upper surface of the head flat, its sides compressed. The suborbital ring of bones, the preopercle, opercle, and upper portion of the subopercle with a rather thick adipose covering. Teeth none in the jaws : a curved row of small ones across the vomer near its head, and continued on to the anterior portions of the palatines, which are contiguous : a single row of about eight large and somewhat recurved ones surround the inner edge of the front portion of the tongue. Gill-openings deeply cleft. Gill-rakers rather widely separated, thick, and equalling in length about 'one-fourth of the diameter of the orbit. Fins the first dorsal anteriorly as high as the body below it, its posterior rays rather more than two-fifths the height of its anterior ones : adipose dorsal fin situated on a line above the last anal ray. Pectorals, if turned forwards, reach to the middle of the eye. Ventrals inserted below the last dorsal ray and midway between the end of the snout and the base of the caudal fin. Anal highest anteriorly where the rays equal the length of the base of the fin. Caudal forked. Scales large, thin, and higher than broad, those along the back adherent, those on the sides more deciduous. Minute ossicles, assuming a stellate or spinate form, are present on the scales of the back and on some of those along the under surface of the abdomen. Those on the sides with roughened or ragged outer margins : the row beneath the lateral-line the largest. Numerous concentric lines upon the surface of the scales. Lateral- line on a row of scales somewhat smaller than those above or below, it is well marked, and passes to the centre of the base of the caudal fin. Air-bladder smaller than in the trout, from which it also differs in the thickness of its fibres and silvery walls, the latter charged with a brilliant substance that separates with washing, at first in the form of spangles. This is next precipitated by ammonia into a silvery deposit, which is preserved for the manufacture of artificial pearls. Colours in an example examined a few days after death, but which had been preserved in spirit, it was of a light olive along the back, becoming silvery white along the middle of the sides, while inferiorly and on the head there was a tinge of gold glossed with purple. A black spot on the upper edge of the orbit, and a smaller one on the snout. A dark longitudinal mark along either caudal lobe near to its outer edge. Edward, who received a fresh one, observes that the colours agree with the number of divisions on the fish. That along the back deep amber, the succeeding one greenish-blue, the third or division below the lateral-line, of a pure silvery white with bright metallic lustre, the others similar to those above but fainter. Belly grayish- white with a tinge of greenish-blue and purple. The top of the head nearly the same as the back, its sides silvery. Eye with a bright silvery iris and blusih-black pupil. It was so transparent that on holding it up to the light the vertebrae could be distinguished. The fish is figured and described by Rondelet, and this was reproduced by Gesner, while Willughby observes " Pisciciclus Romas Argentina dictus, Sphyrama parva, sive Sphyrama secunda species, Rondeletio, Gesner, 1061." This clearly shows that the species of these three authors were identical with the Roman fish, the air-bladder of which was employed to furnish materials for the manufac- ture of artificial pearls. Ray copies, almost verbatim, from the above authors. Artedi's Argentina is identical with that of Linnseus, but not with Gronovius's Sphyrcena. Gmelin in his edition of Linnaeus possibly mixed up, under the designation of Argentina sphyrama, more than one species of fish ; still it is clear that the older authors referred to the deep sea fish, from which materials for false pearls were procui'ed, as stated by Risso. 138 PHYSOSTOMI. Cuvier considered the fish he described in the Memoirs of the Museum as being the same with that of Linnaaus, but Valenciennes changed the name from Argentina sphyrcena to A. Cuvieri. Yarrell has described his Osmerus Hebridicus from a Scotch example, and Valenciennes, while pointing out that it was an Argentina, termed it A. Yarrellii, which Nilsson brought back to A. hebridica. But the question arises are these two forms, A. sphyrcena and A. hebridica, distinct ? It is evident that no criterion can be drawn from the number of fin rays and scales, while although Nilsson found 14 to 20 ccecal appendages in A. hebridica and merely 12 have been recorded in A. sphyrcena, I only found 5 in the example figured, clearly showing how variable these numbers are. Lastly, it has been stated that the comparative height of the body to that of the total length differs in the different species, but here Collett remarks that this changes with age, the example being comparatively more slim in the young. In an example nearly 6 in. long I found the height of the body to be i, in one 8% in. long it was i, and in one 9|- in. long 6^- in the total length (see Jouimal Linn. Soc, I.e., where more instances are recorded). Habits. Of these but little is known, but it is probable that these fish occa- sionally reside at considerable depths, and the species is generally considered rather a deep sea form. The stomach of Edward's example contained the remains of a few of the smaller crustaceans as Darwinia compressa, Protopedata, &c, also frag- ments of Sertularia filicula, Antennidaria antennaria, &c, showing it probably resided among corallines. Breeding. In Edward's fish taken in September the milt was said to have been of a chalky whiteness, 1^ in. in length, but scarcely full. Whether the fish was a partly spent one, or the milt not half developed, could not be ascertained. One of Yarrell's examples taken in June had the roe well developed. Risso states that in the Mediterranean it breeds in spring. Habitat. This fish frequents the shores of Norway to both sides of Scotland, the coasts of Yorkshire, and through the Mediterranean to the Balearic Isles, and along the southern shores of Europe, being taken, we are informed, all the year round in the sea off Rome, where it is of moderate frequency. Mr. Clarke, I.e., has described and figured as new under the name of Argentina decagon, a fish which scarcely appears to differ from European examples except that the fine teeth are said to be wanting. The number of fin rays and scales, as well as the proportions of the body, are identical, while it must be remembered that several European fish have been discovered off the shores of New Zealand. The unique specimen of A. decagon was taken off the west coast of New Zealand. Yarrell * observes that one 8 in. long was taken in June, 1836, full of roe in the Bay of Rothsay, Isle of Bute, and a second 6^ in. in length in November, 1837, near the same spot, on a hand-line baited with a piece of mussel, in about 12 fathoms water and about 200 yards from the shore ; this is probably one of the two specimens now in the Hunterian Museum of the Glasgow University, and is recorded in the Proceedings of the Natural History Society of Glasgow (i, 1867, p. 187). One taken at Kilcreggan, November 26, 1867, the second being probably Mr. Ewing's specimen captured in 1837, and sent to Mr. Yarrell for identification. Yarrell likewise records one taken at Redcar in May, 1852. The one here figured was captured in October, 1879, in Loch Alsh, off the Skye shore, on a hook baited with mussel ; it was sent to the late Mr. Frank Buckland. Edward has recorded a male full of milt taken near Banff in October, 1879. The example here figured is 9*5 in. in length, and the fisherman who captured it stated it was only the second he had ever seen. * Dr. Giinther, Catal. 1866, vi, p. 203, quoted Low, Fauna Oread, p. 225, to show that it ha8 been obtained in the Orkneys, but as he gives the identical reference under Maurolicus borealis, vol. v, p. 389, for Low's single specimen, evidently some error has occurred. Low says his example was not above an inch in length, and gives as synonymous Pisciculus Romce Argentina dictus, Will. Ich. 229 ; Raii, Syn. Pise. 10S ; Argentina sphyrcena, Linn. Syst. 518 ; the Argentine, Brit. Zool. 5J76 ; Brit. Zool. Illust. 42, t. 48." In short, Low accepted Pennant's figure, which is Maurolicus borealis (see page 49 ante) as identical with his Argentine.

Length of head 3-|- to 4, of caudal fin G, height of body Q\ to 7 in the total length. Eyes situated in about the middle of the length of the head, the diameter of each 7 to 12 times in the length of the bead, 4 to 6 diameters from the end of the snout, and 1^- to 2 apart. The dorsal and abdominal profiles nearly horizontal and parallel, causing the body to be of an almost equal height from the head to the commencement of the dorsal and anal fins : its head flattened above, while its length is equal to nearly twice that of the height of the body. Cleft of mouth very deep, equalling about half the length of the head : lower jaw a little the longer. The middle of the upper jaw is slightly emarginate, and receives the head of the vomer : on either side are the short premaxillaries, which ai-e not nearly so long as the maxilla, which is composed of two pieces, is capable of a considerable amount of motion, and reaches posteriorly to beneath the front edge of the eye. Nostrils large, and nearer the orbit than the end of the snout. Numerous glandular orifices on the head. Teeth* none on the maxillary : large ones and of unequal sizes on the mandibles : present on the vomer and palatines, the inner row of which are the larger, more or less strong and depressible : also fine ones on the tongue. Fins the dorsal is situated in the last fourth of the total length (excluding the caudal fin), and slightly in advance of the origin of the anal. Pectoral placed low down and below the subopercle. The ventral slightly behind the middle of the total length (excluding the caudal fin). Caudal emarginate or slightly forked. Scales small, present on the cheeks, upper portion of the opercle, and over the body. Lateral-line nearly straight. Colours when in the greatest perfection of a green colour, becoming lighter on the sides and beneath : numerous yellow blotches, spots, or lines along the head and body : dorsal, anal and caudal fins of a light ground colour with irregular blotches, spots and bands of dark. When out of season the green becomes of a gray, and the yellow markings pale or white. Varieties. It has been recorded by M. Tilesius that he had frequently seen captured in 1806 and 1807, at St. Petersburg, examples from the Neva in which a single median barbel existed beneath the lower jaw as in the cod. Specimens were not preserved. American examples are said to generally possess 17 anal l'ays, but occasionally 19 ; the example figured from Gloucestershire had 18. Montalambert (Hist. Acad. Sc. 1748, p. 27) observes that in the river Gabard in Prance there is a pool containing blind pike. Names. Hacod, Anglo-Saxon. This fish was first termed a jac7e,f then a pickerel, and lastly a luce. Gedd or gade in or near the Moray Firth and in Lowland Scotch : gullet, Northumberland. Haked, a large pike in Cambridge- shire. Morris, a large pike (Halliwell). Erie, a very young pike. Picche, or, if only nearly full grown, pod (Halliwell). The term pike is suggested to have been derived from the Saxon word piik, signifying " sharp pointed," having reference to the form of its head. Penhwyad, Welsh. Ansjovis, Dutch. In French it is termed Brocket or Brocheton from its spit-like shape, Lance or Lanceron from its speed, and Becguet from its muzzle bearing somewhat of a resemblance to a duck's bill. Considerable discussions have from time to time arisen as to whether the pike is an acclimatized or indigenous fish in this country. We are told Edward I fixed its value above that of salmon, and more than ten times that of turbot or cod. Also that in the time of Henry VIII a large one was sold in February for double the price of house lamb, and a pickerel or small pike for more than a fat capon. Probably more attention was paid to inland fisheries in those days than now, and such forms as possessed insatiable appetites were only kept in numbers * See Tomes, On the Hinged Teeth of the Common Pike, Qy. J. Microp. Sc. xviii, pp. 1-16, pi. i. t A jack or pickerel becomes a pike at 2 feet (Walton) and 2 lb. or 3 lb. weight. Some see no distinction, calling all pike, others fix the limit iu ditfereut ways. ESOCID^E. 141 sufficient to supply tlio rich, consequently pike were not so plentiful. As, on the other hand, the salmon fisheries were much more abundant in those days than they are at the present time, this would account for the high price of pike kept in stews, which could only have been within the means of the wealthy should they have to purchase them. If we look at the geographical distribution of this fish it certainly ought to be indigenous, while, so far back as the reign of Edgar, we are told by Leland that one of large size was taken in Remesmere, Hunting- donshire. In heraldry the luce or pike occurs in the arms of the Lucy or Lucie family so far back as the reign of Henry II. Habits. This strong, active and voracious fish possesses an omnivorous appetite, consuming its smaller neighbours, including those of its own species, and often does not hesitate to fatally mutilate such as arc too large for it to consume. It prefers slow-flowing, weedy rivers, ponds and lakes, but its haunts vary with the season of the year and the nature of the water it inhabits. It swims higher in fine warm weather, and may sometimes be seen basking or sleeping at or near the surface, while in winter it keeps at greater depths, and they have sometimes been found associating together in considerable numbers in some sheltered situations. While an annual migration in spring-time has been observed in the Cam ; into which river they come in shoals, doubtless from the fens in the neighbourhood of Ely where they are bred (R. Sheppard). It prefers silent, still, or placid waters where there is abundance of weeds and flags, or reeds, docks, bullrushes, water-lilies, and broad-leaved vegetation : or it will lurk in the shallows among weeds, or where a wall projects into the water, or behind a sunken tree or other suitable object. Its appetite is almost insatiable : it does not refuse the frog, the vole or water-rat, the common house-rat, plump puppies just opening their eyes, tender kittens, even the weasel (Field, October, 1882), a fox (Dr. Genzik), and in Dr. Crull's Present State of Muscovy (1698) it is mentioned that one of these fishes had an infant child in its stomach. The unwary duck* or duckling, gosling, or even geese which swim across its haunts, a swallow skimming along the surface of the water (Mag. Nat. Hist. 1834, vi, p. 400), the dabchick, the coot, and the moorhen alike fall victims ; it has even been known to lay hold of a swan by the head occasioning the death of both (Hardwicke's Science Gossip, 1866, p. 139), while one of only 2-| lb. weight seized a tame cormorant which was engaged fishing and choked itself while endeavouring to swallow it. When emboldened by hunger a pike has been known to attack otters, dogs, asses, mules, oxen, horses, and even men, boys bathing have been seriously injured by their teeth, and one embayed by falling water, finding itself being attacked by a man, became in its turn the assailant, and did not retire beaten from the conflict. It will also take inanimate objects, as a toy-boat which was being sailed across a pool : or a piece of cork attached to a string, and once having seized an object it holds on most tenaciously. It is said to distrust sticklebats, due, it is supposed, to the number of young pike which become choked by these spiny little fishes : while perch are believed not to be a desired food, although it takes it as a bait. It has been known to seize a toad flung into the water, but it is immediately rejected : and sometimes it similarly declines to swallow the rat. An account was given in the Field (Sept. 2nd, 1882) of two pike each weigh- ing about 10 lb. dashing at the same time at a live bait, and then at one another fighting like a couple of dogs. Mr. Stanley (Zool. 1845, p. 1035), on December 25th, 1843, observed a pike lashing the water with his tail. On pulling it out he found two pike of about 1 lb.weight each, the head of one being entirely within the * A curious incident occurred on the River Snir, near Tulla Bridge, about a mile from Thurles. A number of ducks were swimming on the river, when one of them, uttering a loud " quack," was seen suddenly to disappear. Some young men, going through curiosity to the spot where the duck had vanished, found near the bank of the river an enormous pike floundering about, and so utterly helpless that they had very little difficulty in landing it, when they found the duck which it appeared the pike had seized, but was unable to swallow. The monster, whose insatiable voracity had caused its death, weighed nearly forty pounds. 142 PHYSOSTOMI. mouth of the other, the snout coming out at the gills of the fish which was holding it. Ekstrom mentions finding a 20 lb. pike with the skeleton of an osprey, Falco Jialicetus, still attached to it. Lloyd likewise observes that Dr. Mellerborg, of the Uddeholm establishment, vouched for having seen an enormous pike with an eagle fastened to its back, lying dead in a piece of ground which had been overflowed but from which the water had retreated. Pike have been captured by trimmers having swallowed two separate baits, as if showing that they do not suffer much pain when being hooked. Pennell gives an account how a trimmer having been set in the Avon, a heavy pike was found captured the next morning, on opening it a second one of considerable size was seen, while inside this second was a third of about f lb. weight. It has obtained credit for one good trait (in addition to its eating its younger relatives) and that is that it has been said not to devour tench in consideration of its being its medical attendant. For the popular belief in many localities is that it rubs itself against the pike's wounds and exudes mucus which possesses healing virtues. In a work Civitates, Orbis, Terrarum (Colon, 1572-1606) are repre- sentations of a series of English costumes and a view of selling live pike. There the custom is shown of how the vendor cut open the belly of the fish in order to show its condition, this was stiched up again if a purchaser was not found and returned to the water. But unfortunately it has been repeatedly proved that if hungry, the pike will make a meal off the tench, while the troller is aware that this fish may successfully be employed as bait. During periods of great droughts, pike are often found to disappear mysteriously from some pieces of water reappearing on the recurrence of rain. Mr. Pennell gives an account how one was found jumping and working about in the wet grass, evidently making its way from the breeding ground to the river distant some half dozen yards, two-thirds of which distance it had traversed. It is suggested they may travel like eels over dewy grass, and several instances are related how pike have appeared in ponds or pieces of water in a most unaccount- able manner. Isaak Walton observed that it is not to be doubted but that they are bred, some by generation, and some not, as namely, of a weed called " pickerel- weed," unless learned Gesner be much mistaken. No doubt this weed in which the spawn is often deposited, may, if removed to another pond, be a means of stocking it with pike, or such may occur in other ways through the instrumentality of frogs or aquatic mammals (see Introduction). Considerable differences of opinion exist with reference to the desirability of having pike in fisheries : but there are few who would advocate the cultivation of this voracious monster where salmon and trout thrive. Their introduction into the Teviot, says Stoddart, has, there is no question, conduced very materially to injure the salmon fishing, nor have the trout remained wholly unscathed. He observes upon having taken 5 or 6 salmon fry out of the stomach of a single fish : and also states that in some Scottish Lochs pike have been known to consume their own weight of bait every day. Pennell computes that in stews a 5 lb. or 6 lb. fish would eat, if permitted, twice its own weight of fish every week. While, as I have already remai-ked (page 104), pike in trout preserves not only diminish the inhabitants but scare them to that extent that they become timorous of feeding, and frequently occasion great falling off in the general condition of the trout. On the other hand it has been contended that it gives sport to the angler when the fly-book is closed due to droughts, or else during the cold months of the year, and pike will not destroy fish ova. While it may be introduced into canals, lakes, meres, and sluggish rivers, where no good fish will flourish. In Wild Sports of the Highlands it is observed that in all lakes of considerable size where the pike were plentiful the trout have improved very much in size and quality, and not diminished in numbers to any great extent. There are doubtless localities where this fish is suited for, but their undue increase has to be guarded against, because with their ravenous appetites and rapid digestion they require a ESOCIL\E. 143 large stock of food present in the water for their sustenance. Jesse tells us how he threw five roach, each about 4 inches long, to a 5 lb. pike, which swallowed one after another of the first four, but the fifth it retained in its mouth for about a quarter of an hour evidently waiting until digestion should make room for its rejoining its companions. Means of capture. This fish is taken for food, as sport or with reference to the condition of the fishery in which it resides. If it is desired to diminish its numbers, it stands to reason that such as are captured prior to spawning time, as during February or March, are more valuable for this purpose than should the ova have been deposited. Netting is most easily employed during the winter months, due to the absence of weeds. Also at such times as they ascend ditches, drains, and other localities for breeding they may be destroyed with comparative ease. They may be speared or wired, or snatched or shot while basking, or desti'oyed by trimmers, a modification of which is termed a ligger in the eastern counties. The angler, however, generally endeavours to take the pike by means of trolling, divisible into such as are fished for with live or dead bait. Either of these baits may be employed on spinning also termed snap tackle, or else on gorge tackle, which latter, as its name implies, is intended to be swallowed prior to the fish being struck. There are likewise various artificial baits employed as the spoon or imitation fish. While large gaudy flies which may be likened to coarse bodied salmon-flies are occasionally found to be killing. In Norfolk very great success is sometimes obtained during severe frost on the broads by breaking a hole in the ice and putting down a baited hook (Lubbock). Sharp frosts are sometimes desirable to induce these fishes to feed. Thunder is sometimes auspicious or the time just prior to a flood as the waters commence to swell. The months of November and December are generally considered the best months for the angler. Baits. The young pike, gudgeon, gold-fish, dace, roach, rudd, tench, bleak, perch, or a frog. A large fish prefers a good mouthful, consequently a large bait is esteemed preferable to a small one, roach or*rudd of a pound weight is not too large. Small baits are attacked and ruined by the small pike ; however, if hooked they become excellent lures to their larger relatives. Breeding. March and April, sometimes as early as February, especially in Ireland. The ova are small and numerous but very various in number, a 35 lb. fish contained 43,000 : a 32 lb. fish, 595,200 : a 28 lb. fish, 700,000 : a 28 lb. fish, 292,320 : a 24 lb. fish, 224,640. They quit the open waters in pairs (being as a rule monogamous) when the breeding season arrives, the male which is the smaller following the female, and they seek small bays, creeks, shallows and con- tiguous ditches where their eggs are deposited among the weeds and leaves of aquatic plants. The pike commences to breed at about three years old, while the younger fish spawn prior to the older ones. It has been remarked that spawning being over the female often eats her husband. After breeding they become unfit for food, hardly returning to condition prior to June. Monstrosities of the embryos are common, and as pointed out by Lereboullet, (1864) they are either double, the production of a superabundance of the plastic embryonic matter ; or simple in which an individual is partially or wholly defec- tive. This disposition to monstrosity does not appear to be consequent upon any external influences but to be inherent in the ova : although some external causes may occasion an arrest of development more or less complete. Life history. It has been well observed (Lubbock, Fauna of Norfolk, p. 190) that this fish from the very ovum appears to manifest the stern and solitary energies of its nature. In summer almost every distinct puddle in fens where turf is cut has its tiny tyrant in an infant pike ; here it enacts despotic sovereignty, and lords it over tadpoles and fry, till fate arrives in the shape of a heron, or the first floods of autumn sweep it to the river or broad. Of course the rate of growth may be accelerated or retarded by many local circumstances. 144 PHYSOSTOMI. Mr. Southwell informs me (on the authority of the agent of the estate) that when Scoulton Mere, in Norfolk, was cleared out they put in some young pike of about i to 1 lb. each : after ten or twelve years they had increased to 18 lb. Stoddart considered that two-year-old fish were from 3 to 5 lb. weight. In some waters they will rapidly attain to a certain size, subsequent to which their further increase is slow. Perhaps in open waters it is not an unsafe estimate of 1 lb. yearly for the first two years, and afterwards If to 2 lb. for seven or eight years, and subsequently at a less rapid rate. Growth does not always correspond with the amount of food received ; such as are well fed in aquaria do not appear to increase so rapidly as such as are in the open waters. The age to which this fish attains has been variously estimated : Lord Bacon placed the limit of its existence at about forty years. Ryaczynski adduces an instance in which there were reasons for believing that a pike was ninety years old. But if we go back to tradition we are told this fish lives for centuries. It is stated that a pike was captured in 1610 in the Meuse bearing a copper ring on which the name of the city of Stavern was engraved with the date 1448. While a still more incredible account is given how Frederick II, in October, 1230, inserted a brass ring into the gills of a pike bearing a suitable inscription, and that this fish was recaptured 267 years subsequently 17 or 19 ft. long and weighing 5501b. The skeleton was preserved in the Cathedral at Mannheim, but on its being examined by a German anatomist, it was found that the length of its vertebral column was obtained by using the bones of several fish. Diseases. Valenciennes mentions having an example taken in the autumn of a pale white, the whole of the body being covered with red spots somewhat resembling small-pox. It is tormented with parasites. As food. Opinions differ as to its value, possibly due to the character of the flesh for good or for bad being influenced by the waters in which it resides. Those from rivers have a white firm flesh, are easy of disgestion, and as a rule superior to the pond ones, while even various localities, due to local circumstances, affect the character of the fish. Those from the Thames are firm and of good flavour, like- wise those from the mouth of the Medway, where they find plenty of smelts, also those from Horsea Mere and Heigham Sound, and Stoddart praises very highly those of the Teviot. Those from Scotch lochs and muddy waters are not generally approved of, being more or less soft, slimy, and disagreeable both in taste and smell. In Ireland it is not esteemed during February and March while spawning, but Stoddart observes that in Scotland they are considered by many epicures as finest in condition when full of roe. The roe is said occasionally to produce vomiting, purging, and other deleterious symptoms, while Linnaeus saw it being made into bread at Lyksele, in Lapland. As soon as a pike of a suitable size has been taken it should be disembowelled and cleaned, while it will be improved by being crimped like a cod. Large fish are coarse. The upper or back part is not edible unless the bones are removed by an expert cook. Boiled, it is insipid ; stewed, with spices and a bottle of good old crusted port, it becomes passable ; stuffed and baked, it is perhaps a trifle better ; filleted, it is almost nice. Uses. Its jaw-bones in olden times were recommended to be powdered and given in pleurisy, gravel, stone in the bladder, and other diseases. In some countries it is salted and dried. The heart and galls were used as medicines for agues and other fevers, and the latter likewise for affection of the eyes. Its roe used to be prescribed as an emetic. . As the bones of the head form a sort of cross, such have been worn as a preventative against witchcraft. In some parts of Hungary and Bohemia it is considered an unlucky omen to see a pike plunge in stagnant waters before mid-day. Its bite is hard to be cured, being a punctured and jagged wound. Habitat. From Scandinavia throughout the continent of Europe and the northern portions of Asia and America, Rondeletius observes that it enters the sea at the mouth of the Rhine, and is found in salt water pools bordering the Mediterranean, but that such fish are dry and insipid food. ESOCID^E. 145 In Scotland it is widely spread in lochs, rivers and other appropriate localities * in the Forth it is frequently seen in brackish waters and often observed off Stirling bridge basking in the shallows. It is found throughout England and Wales in suitable pieces of water, especially as in Yorkshire and Norfolk ; it is absent from the Isle of Wight and likewise from Cornwall, and a few years since it was said only to be found in Slapton Ley Lake in Devonshire, but now it exists in the Exe where it has driven the trout from certain portions of the river. In Ireland, according to Thompson, in the County of Londonderry, in salt water between Derry and Culmore (Ordnance survey), in all suitable lakes in the northern part of the island Lough Neagh, L. Derg, &c. County Dublin (Ball) ; the Shannon, Lough Corrib, L. Mask and L. Carra (McCalla). The size to which the pike attains in these islands* is rather questionable, but certainly some now captured exceed the largest Pennant ever heard of in his time (1776), which weighed 35 lb. Some of the statements made by authors would seem to require explanation. Sir J. Hawkins refers to one 170 lb. weight taken in 1765 which one would have supposed Pennant would have heard of. Colonel Thornton alludes to one of 146 lb. captured at Lochmaben. Daniel (Rural Sports) to one upwards of 7 feet long and over 72 lb. weight from Loch Ken, Kirkcud- brightshire. Dr. Griersen one of 61 lb. from Loch Ken (Thomson's Ann. of Phil, viii, p. 428). One of 78 lb. taken in August, 1830, in County Clare (C. Mayne). On February 27th, 1880, two pike were taken angling in Norfolk, the one 30|, the other 36 lb. weight. The example figured is 12 inches long and from Gloucester- shire. * " About seventeen years since, when visiting the late Marquis of Clanricarde, at Portumna Castle, two gentlemen brought to the Marquis an immense pike, which they had just caught in the River Shannon, on the banks of which they had been taking their evening walk. Attracted by a noise and splashing of the water they discovered in a little creek a number of perch driven on shore, and a fish which, in pursuit of them, had so entangled himself as to have a great part of its body out of water. They attacked him with an oar, which by accident lay on the bank and killed him. Never having seen any fish of this species so large they judged it worth the observation of the marquis, who, equally surprised at its magnitude, had it weighed, and to their astonishment it exceeded the balance at ninety-two pounds. Its length was such that, when carried across the oar by the two gentlemen, who were neither of them short, the head and tail touched the ground." The Sportsman, 1839. 10 14G PHYSOSTOMI. Family, IV. SCOMBRESOCID.E. Pharyngognathi malacopterygii, Miiller. PseudobranchiaB glandular, concealed. Margin of the upper jaw formed mesially by the premaxillaries and laterally by the maxillaries. Barbels present or absent. Lower pharyngeals united into a single bone. Dorsal fin rayed, with or without Unlets posterior to it, situated opposite the anal, and in the caudal portion of the vertebral column: no adipose dorsal. Scales present, frequently a keeled row along either side of the free portion of the tail. Air- bladder generally present, sometimes cellular internally, and destitute of a pervious pneumatic duct. Stomach and intestines in an undivided tube. Pyloric appendages present or absent. Synopsis of Genera. 1. Belone. Both jaws elongated into a beak. No finlets. 2. Scombresox. Both jaws elongated into a beak ; finlets behind dorsal and anal fins. 3. Exoccehis. Jaws short. Pectoral fins elongated into organs for flying. Among the fishes belonging to this family some are oviparous, others viviparous. The eggs of many have filaments springing from their outer covering, and which enable numerous ova to adhere together in a mass, or attach themselves to contiguous objects, preventing their subsiding into the mud. It has been suggested that they are thus suspended so that by the ebb and flow of the tide they may be constantly bathed by different water. Professor Ha3ckel observed these filaments present in the eggs of gar-fish, Belone; saury, Scombresox ; half- beak, Hemiramphus, and flying-fishes, Exocce-tus ; while Ryder has remarked on having found similar filaments in one form of Atherinidw, the Chirostoma notata, but in such they are only four in number, and situated close together. Genus I. Belone, Cuvier. Mastacembehis (Klein) Bleeker ; Bhamphistoma, Rafin. ; Tylosurus, Cocco ; Potamorrhaphis, Gunther. Branchiostegals numerous. Gill-openings wide. Body elongated, sub-cylindrical or compressed. Eyes lateral. The jaws prolonged into a bealc, the dipper of which is formed by the premaxillaries. Fine teeth {or rugosities) in both jaivs, with a single row of long, widely set conical ones ; palate toothed or toothless. The anterior dorsal rays may or may not be elevated, forming a lobe to the Jin, while the middle and posterior ones may be short or elongated : no finlets : caudal usually forked. Scales small. Lateral-line on free portion of the tail, with or without a keel. No pyloric appendages. Cope considers that Belone should constitute a distinct family due to its possessing distinct caracoid bones, and vertebras with zygapophyses, a character unusual among fishes (Proc. Amer. Phil. Soc. xvii, p. 695). Jordan and Gilbert remark upon the absence of gill-rakers in Belone exilis and some other species which it is proposed to unite into one genus Tylosiirtis, Geographical distribution. Temperate and tropical seas ; some species resident in fresh waters. Uses. Indifferent as food ; all forms appear to possess green-bones. They are very destructive among small fishes. scombresocim;. 147 In the very young the upper jaw is very short, as in the tropical HemirampJius, but gradually increases with age until it becomes almost as long as the mandible. 1.

Length of head 3j to 4, of caudal fin 7|, height of body 15 to 16 in the total length. Eyes large, 2j to 2f diameters in the length of the postorbital portion of the head, 6| to 7 diameters from the end of the upper jaw, and 1 ^ diameters apart. Upper surface of head not grooved : some slight grooves about the superciliary region. Maxillaries concealed by the preorbital. Upper jaw not so long as the lower, which latter has a soft termination. Teeth small, in some examples a small oval patch is present on the vomer, in others it is absent. Fins the anterior dorsal rays are elevated forming a lobe, while the posterior ones are of about the same length and terminate opposite the anal ones, which is some distance from the base of the caudal fin. Pectoral, if turned forward, does not reach the eye. Ventral situated nearly midway between the opercle and the base of the caudal fin. Caudal forked, lower lobe the longer. The free portion of the tail compressed, nearly twice as long as high, and deeper than broad. Colours of a sea-green or bluish-green along the back, becoming of a changeable blue and purple along the sides, and silvery white beneath. Fleming (Brit. Anim. 1828, p. 184) observes upon Esox Brasiliensis, Couch, 10* 148 PHYSOSTOMI. being the young of this species : while many authors seem to have been doubtful whether the various European Heyniramphi were not in reality the young of Belone. The young. Couch's magnified figure of the blunt-headed half-beak, the specimen having been half-an-inch in length, shows the fish in the earlier stage, when the lower jaw is commencing to increase in length ; while his European half-beak, at a little over 3| inches in length, demonstrates the fish with the lower jaw grown, but the upper jaw still almost stationary. In Liitken's " Spolia Atlantica," p. 567, will be found a complete series of illustrations, showing the various stages of evolution of the jaws as they become developed with age. Steindachner (Sitz. Ak. Wiss. Wien, 1868, lvii, p. 732) remarked upon the identity of Belone acus, Risso, with B. vttlgaris, the distinction between the two forms resting principally upon the latter possessing a small ovoid patch of vomerine teeth, which is said to be absent in the latter. It is remarkable that the finest example in the British Museum from the British shores is destitute of this patch of teeth, although it is present in others. They are likewise absent from the Devonshire specimen which I have figured. Canestrini 1. c. observed upon finding vomerine teeth in an Adriatic example. Professor Giglioli informs me that these vomerine teeth may be present or absent in Mediterranean and Adriatic forms, and he looks upon Belone vulgaris, B. acus, and B. Euxinus as pertaining to one species. Names. Sivord fish, green-hen or green-bane, Scotland: green-bone or green- bach, guard-fish, gar-pipe, horn-fish, needle-fish or long-nose, gore-bill, sea-needle, mackerel-guide, which name it has received from its coming towards shore a little prior to the appearance of the mackerel. Gerrich, Cornwall. Hornkecke (Palsgrave). Whaup-fish. In Ireland, horn-eel (Belfast Bay) ; mackerel-scout (Strangford Lough) ; spearling (Portrush); Spanish -mackerel, according toNimmo, at Pioundstone. Its snout is termed gore-bone in some places. Mar nodwydd, or Com big, Welsh. I)e geep, Dutch. L'Orphie, French. Habits. Gregarious, migratory, and very voracious, frequently approaching the shore in lai'ge assemblages, and though stragglers may be taken all the year round, it appears to arrive in shoals about March or April, and retires to deeper water late in the autumn, being absent throughout the winter and spring. In the Northern Herald (Inverness, November 22nd, 1844) it was observed that within the last three weeks this fish had been abundant ; its visits are not periodical, either as regards seasons or cycles, in fact twenty-two years had passed since they came in considerable numbers ; about sixty years since there were large shoals, and they were known as Gobbaiche ardnasoar, or " snipe-fish." Although as observed the gar-fish is usually gregarious, Thompson remarked that in Belfast Bay it is generally found singly. Mr. Cornish (Zool. 1865, p. 9814) well describes the appearance of a shoal of these fishes when chased by the tunny, how they scudded rapidly over the face of the sea as though they were actually swimming on the surface, having the larger portion of their bodies in the air. When in pursuit of shoals of small fish it appears to be springing over the waves after them. It jumps over floating substances sometimes in a peculiar way, shooting itself bolt upright and alighting in the water tail first. Mr. Couch recorded how in 1865 he found the upper jaw of a gar-fish transfixed through the body of a mackerel. Mr. Dunn observed upon another having similarly gone through the body of a pilchard, he also informed me, July 25th, 1881, that he had obtained that morning a mackerel with the jaw of a gar-fish transfixing the body just under the pectoral fin, where it had broken off. The same accurate observer remarked that he has reason to believe that they used their beaks as a ram against their prey, sometimes transfixing their eyes : should they do this, of course both would be penetrated. S. Clogg (Zool. June, 1874, p. 4160) observes upon a salmon-peal having been attacked by a gar-fish. It had run its under jaw completely through the peal, and it must have been broken off either by the force of the blow or by the struggles of each fish to free itself. The peal, which weighed nearly 4 lb., was struck behind and quite above the pectoral fin, the jaw SCOMBRESOCIDvE. 140 of the gar-fish thus passing through the thickest part of the peal. Couch observed that it is an indiscriminate feeder, eating any animal substances it can seize. Thompson mentions a 15-spined stickleback having been found in the stomach of one captured August 10th, 1850. Its digestion appears to be very rapid. Means of capture. It will tako a bait, but when hooked makes most vigorous efforts at escaping. On the coast of Donegal it is captured in the following way : Nets are fixed on wooden frames and allowed to float about, these fish jumping over the sides become captured : the same plan is employed at Land's End. They are frequently taken in mackerel nets, and during the last half of the year numbers are captured in Cornwall in seine nets. Baits. Pieces of fish, mussels, &c. It never plays round a bait, but seizes it as if it were living. It strikes obliquely upwards, hence it happens that when it takes the hook, the first notice of the capture is the fish starting into the air with the line, and then beating itself about on the surface to get rid of the hook, and in doing this it always emits a very strong and peculiar odour (R. Couch, Zool. 1847, p. 1613). Breeding* Along the south coast of England this fish breeds in May and June, but, according to Andrews, in July in Dingle and Ventry Bays in Ireland. On May 14th, 1881, Mr. Dunn sent me a portion of a mackerel net with many ova of the gar-fish attached to it by tentacular filaments springing from the outer surface of the eggs (plate cxxvii). The fish having become entangled in a mackerel drift net, had voided its eggs while endeavouring to escape, and these latter, owing to their peculiar appendages, are enabled to attach themselves to any object in the vicinity (see page 146). Mr. Dunn obtained another supply on June 25th, and on making some experiments found that the filaments will even adhere to polished metal. These eggs when extruded must float in the sea with their long filaments waving about until they meet with some object to which they can attach themselves ; or they may serve to bind together large numbers of eggs into one mass and fix such to some suitable substance. I have already alluded to the peculiar manner in which the jaws of this fish are developed. Under one inch the upper pi*ofile of the snout is somewhat obtuse, the upper jaw very short, the lower a little longer. This stage has been termed Hemiramphus obtusics, R. Couch, although the fishermen assured him they were the young of the gar. As the fish becomes from 2 to 3 inches in length, the lower jaw has much increased in length, being many times longer than the upper jaw, which is almost triangular : at this stage it has been termed Hemiramphus Europeus. On October 28th, 1880, I obtained an example 8'6 inches long from Devonshire : the entire length of its head was 3T inches : of the lower jaw from the angle of the mouth 2T inches: of the upper jaw from the angle of the mouth 1*6 inches. On November 23rd, 1881, I obtained another from Devonshire, 8 - 5 inches long : its head being 2"8 inches, lower jaw 1*8, upper jaw 1 inch. The foregoing would lead one to conclude that this fish increases rather rapidly in length, attaining to about 8 inches in length at three months' age. The very young Lowe found in Norfolk (July 6th, 1868) had been living upon Entomostraca. As food. Pretty good, but owing to the green colour of the bones of this fish, both before and after boiling, a prejudice against eating it is entertained in some localities. They are often plentiful in the London market, especially in the spring. Large numbers used to be sent there from the coasts of Kent and Sussex. Their smell when first captured is not always agreeable. Parnell states that many persons consider them superior to mackerel as food, being firmer, whiter in the flesh and possessing much the same flavour, but it is generally considered more dry. Uses. Bait for ground fish when other kinds run short, for which when cut into strips they are found very efficient. Habitat. Distributed from Iceland and the Scandinavian coast, the Baltic, North Sea, and Atlantic coasts of Europe to the Mediterranean. * See article on the Development of the Silver Gar-fish, Belone longirostris, T. A. Ryder, Bull. United States' Fish Commission, vol. i, 1881, p. 283. 150 PHYSOSTOMI. In the Orkneys and Zetland it is not uncommon (W. Baikie) and extends in more or less abundance during certain seasons around the British coasts. Banff, not scarce at certain seasons (Edward) : Moray Firth (Harris) : Aberdeen (Sim) : St. Andrews, occasionally thrown on the sands after storms (Mcintosh). It enters the Firth of Forth in large shoals about the beginning of July in company with the mackerel, and remains till the end of August. It seldom ascends the Firth to any distance. Is taken with net and hook, and sometimes found on the haddock lines which have been baited with mussel (Parnell). Berwickshire occasional (Johnston) : Yorkshire, resident off the coast and not uncommon, approaching the shore in summer : in autumn it has been cast ashore in considerable numbers during heavy gales* (Yorkshire Vertebrata) : Norfolk, off which coast it breeds (Lowe) : one is recorded by Lubbock as having been taken within five miles of Norwich. Along the whole of the south coast. Kent and Sussex very abundant. Devonshire not uncommon (Parfitt). Cornwall common. Off Swansea is not infrequent in the Bay, but never in shoals and usually of a smaller size than on the other coasts (Dillwyn). In the Firth of Clyde, May 25th, 1877, the capture of an example 28 inches in length was recorded as a rarity (Flemyng, Nat. Hist. Soc. Glasgow). In Ireland it is taken all round the coast, generally in the latter part of the summer and autumn: a few are also obtained in the early months of the year (Thompson). In some seasons it is common from Cork to Londonderry. The example figured is 28 inches long from Devonshire : the largest example I have collected has been 2 feet 9 inches. Pennant records it up to 3 feet. * Mr. Dunn informs me of an instance in which one of these fishes, just outside the harbour at Mevagissey, was seen and chased by a porpoise. It sprang out of the water and its pursuer followed it upwards of a hundred yards. The gar was now almost in the jaws of the porpoise when a rock jutting a few inches above the sea was arrived at. Over it went the fish, but the heavy porpoise ran its head against the barrier and appeared partially stunned. SCOMBKESOCID^B. 151 Genus II. Scombresox, Lacepede. Grammiconotus, Costa (Young).

Eyes 2^ to 2| diameters in the length of the postorbital portion of the head, 4| diameters from the end of the upper jaw, and 1 diameter apart. Jaws in the adult curved slightly and gradually upwards, the upper being a little the shorter. Posterior extremity of the maxilla not covered by the preorbital, it extends back- wards to about 1 diameter of the eye anterior to the orbit. Preorbital large and somewhat quadrangular in shape. Teeth fine ones in the jaws; none on the vomer, palatines, or tongue. Fins the dorsal commences slightly behind the beginning of the last third of the total length, its anterior rays rather higher than half that of the body below it, the finlets continued almost to the base of the 152 PHYSOSTOMI. caudal fin. Pectoral as long as two-thirds the height of the body, its posterior margin somewhat concave. Ventral s inserted midway between the angle of the mouth or the front edge of the eye and the posterior end of the caudal fin, the latter being deeply forked. Scales a somewhat keel-like edge commences on either side of the fish on a level with the lower edge of the gill-covers, and passes along the entire length of the body. Scale-like appendages over the middle of the base of the caudal fin. Coloiirs back of a deep rich blue, below which is a broad burnished and shining silvery band, having a dark lower edge, abdomen silvery : upper fins dark coloured, lower ones and pectoral yellowish. The evolution of the jaws in this fish is much the same as described in the gar-pike (see page 149). Varieties. Valenciennes separates the Mediterranean from the oceanic form under the belief that the former has no air-bladder. Professor Liitken (Spolia Atlantica) has shown however that this organ may be present in the Mediterranean forms. Moreau observes that it may be absent. As no other differences exist except this inconstant one I have not considered them to denote distinct species. Names. Skipper: saury: saury-pike: skip-jack : skopster : halion. In Scot- land, gowdnook : gosnick : Egyptian herring. Habits. Gregarious, migratory, in the summer being mostly at or near the surface, but during the autumn frequenting deeper water : it is usually found further out to sea than the gar-fish, while it has an extensive range : instances are on record in which it has ascended rivers as high as fresh-water. It first appears off Cornwall about the latter half of June or commencement of July, and in the autumn frequently shows itself in enormous schools ; while it leaves the coast prior to the end of November. It is constantly in motion, moving with great rapidity, frequently springing out of the water by scores at a time and giving much the appearance of a shoal of flying fishes. It has been frequently known to spring out of the water into the fishermen's boats, especially during stormy weather. Mr. Dunn considers the skippers as natural enemies to the pilchards : Couch held the same views. In the year 1825 skippers and pilchards were enclosed in pilchard seines together, and before they could be taken into the boat, thousands of the pilchards had their eyes knocked out by the skippers, and scores of pilchards were transfixed through the body by the beak of the skipper. The fishermen were first made aware of these fishes being on the coast by the noise they were making in the night, the one attacking, the other running away. This battle continued more or less along the coast each summer from 1825 to 1834. The fishermen consider the presence of the skipper is an hindrance to the successful taking of the pilchard. Entomostraca, small Crustacea, and sea-weed have been found in its stomach. Means of capture. In Cornwall they are frequently taken in July and August in numbers by drift nets a few leagues from the shore : R. Couch observed that he had seen 8000 enclosed in one pilchard seine net. The largest catch of these fishes at Mevagissey, where they are annual visitors, has been 100,000 (Dunn). Baits. It has been taken with a bait. Breeding. The eggs of the Scombresoz saurus are furnished externally with filaments as in the gar-Hsh (page 146), while the life-histories of the two are also very similar, but the young of the skipper appear to be found further out to sea, and the base of the maxilla is more concealed by the preorbital. Liitken (Spolia Atlantica) p. 567 has figured the heads of this species from a very early age up to that of the full-grown, showing how the jaws are gradually evolved, the disproportion between the length of the two being much less than occurs in Belone. As food. Said to be fair. Habitat. Atlantic coasts of Europe, Africa, and North America. Also the Mediterranean. Low observed that last year (1775) such a glut of these fish set into the head of Kerston Bay, that they could be caught in pailsful ; numbers were taken and heaps flung ashore. They were from 9 to 12 inches long, and had not been observed there previously. Low considered they had been driven out of their SCOMBRESOCID^E. 153 course. As a rule in the Orkneys and Zetland rare (W. Baikie) : Banff rare (Edward): Aberdeen (Sim): St. Andrews not uncommon (Mcintosh): enters the Firth of Forth almost every autumn in considerable shoals, and being stupid inactive fishes are found in hundreds on the shallows when the tide retires, with their long noses imbedded in the mud (Pennant). The same author records great numbers having been thrown ashore on the Leith sands near Edinburgh, after a great storm in November, 1768. In Yorkshire is occasionally taken in harbours and shallow waters but is reported from Scarborough only (Yorkshire Vertebrata). An example about 15 inches long was taken off Norfolk in October, 1843 (Fisher) : off Devonshire occasionally appears in large numbers, and Parfitt (Fauna of Devon) remarks that he saw a great many taken in a seine off Seaton in 1870. Not uncommon, often abundant off Cornwall. Mr. Cornish (Zool. p. 1463) observes upon one having been pumped up on board a fishing boat in September, 1868 : the same author remarks upon its being well known off Welsh ports. At Swansea Dillwyn never heard of it except on Turton's authority. In Ireland Templeton observed that it is seldom found on the coast, and he was never able to procure a specimen until one was caught near Long Bridge, Belfast, in 1820. Thompson received one 12f inches long from Belfast, stranded after a gale on September 17th, 1840, a second was also taken, and a third on October 7th. Sampson includes it among the fish of Deny. Ogilby (Zool. 1876, p. 4753) observes that it is decidedly rare on the north coast : he obtained one example, cast ashore at Portrush, co. of Antrim, during the last week in September, 1875, while but few years pass without some examples being obtained there in this manner. Newcastle, co. Down (Thompson). The specimen obtained was taken on a handline, when fishing for bream, westward of Crowrock, on a fine night. They not unfrequently leap into the canoes (Andrews) : the same author refers to one taken at Ballina in the county of Sligo. The example figured is 11 inches long from Mevagissey. This fish attains to 18 inches in length. 154 PHYS0ST0M1. Genus III. Exoc(etus, Artedi. Cypsilurus, Swainson : Halocypselus, Weinland : Parexocoetus, Bleeker. Body 'moderately oblong. Gill-openings very wide. Jaws short, the premaxillaries and maxillaries separate: mandible in some species with a tubercidar prolongation. Barbels present or absent. Teeth, when present, minute and rudimentary. Pectoral elongated, used as an organ for flying : the dorsal fin may be much or only moderately elevated : ventrals long, short, or of moderate length. Air-bladder large. Pyloric appendages absent. Bleeker instituted the genus, Parexocoetus, for some species as E. mento, Cuv. and Val., destitute of barbels but with a short tubular prolongation of the lower jaw, as if an aborted attempt at elongation as seen in Hemiramphus. Barbels and transverse bands may be symptomatic of the immaturity of the specimen. Liitken draws attention to the following important generic characters, which have been overlooked. There are those in which the second ray of the pectoral fin is entire : others in which it is deeply cleft, and when the second ray is thus cleft the third is always the longest (Vid. Medd. 1876, pp. 389-408, pi. x). Geographical distribution. Seas of tropical and semi-tropical regions, extending into more temperate zones. 1. Exocoetus volitans, Plate CXXVIII.

Eyes diameter of each 3 to 3i in the length of the head, nearly 1 diameter from the end of the snout, and 1|- diameters apart. The form of the body is liable to modifications, in some having a convex superior profile or it may be broad and flattened almost as far as the origin of the dorsal fin. Upper surface of the head flattened. Snout obtuse : cleft shallow : the lower jaw slightly longer than the upper : the superior maxilla hidden by the preorbital when the mouth is closed. Teeth in jaws minute. Fins the dorsal commences on a line above the vent, its first ray simple : the pectoral reaches to the base of the caudal fin, its second ray divided, its third the longest. The ventrals are inserted a little posterior to the middle of the distance between the end of the snout and the base of the caudal fin, they are elongated, being more than \ longer than the head. Anal commences beneath the posterior dorsal rays. Caudal lobed, lower lobe much the longer, but the proportions vary in individuals. Colours bluish-gray along the back, silvery on the sides and beneath. Dorsal fin grayish- white, caudal brown. Pectoral gray with a light outer edge. Ventral and anal whitish or bluish. Names. Flying-fish. Hirondelle de mer, ou Hareng volant, French. SCOMBRESOCIDvE. 155 Habits. A marine gregarious* fish, which leaves the water, springing into the air, due to fear of some danger, not for the purpose of seeking food : it would seem that the distance it can cover in such nights is limited, while some have asserted that they are unable to voluntarily change the direction of their course. Professor Mobius (Zeits. fur wiss. Zool. Band, xxx, suppl. p. 343) records his observations on the flight of Exocoeti. He observes that they spring with great velocity out of the water, regardless of the direction of the wind or course of the waves. During their flight they do not make any regular fluttering movements with their pectoral and ventral fins, but merely keep them extended or spread out. Rapid vibrations may however be perceived in their outstretched fins. The hinder part of the body is kept at a lower elevation than the fore part. The cause of these movements through the air is due to the springing movements which they impart to their bodies by means of their very powerful lateral muscles, in the same manner as other fish employ them for propulsion through the water. They spring out of the water with great velocity due to the air presenting less resistance than the water, and when they fall into the sea their outstretched fins act like a parachute. The action of the wind may be favourable or the reverse to their flight. During the day-time they can choose the direction of their spring, and so avoid ships. At night-time, due to the deficiency of such a power, they may fall into a vessel. As any air in strong motion striking against any obstacle (as a wave or side of a ship) rises, this would also raise the fish and thus lift it on to the vessel. It may be a combination of an oblicpae forward movement of the fish, acted upon by the wind. Mr. Howard Saunders (Zool. 1874, p. 3839) observes that not even the frigate-bird was ever seen by him to swoop at, much less to catch one on the wing, and in South Sea Bubbles, either the "Earl" or the " Doctor " ridicules the very idea of any bird being able to do so. Means of capture. Off the British coasts it is merely taken by chance. Mr. Smith (Zool. 1875, p. 4413) details how in January they angled for these fishes, while on a voyage from Peru to Callao, " a variety of baits were employed in their capture bits of red bunting, small spoon-baits, and artificial minnows, of these the most taking being a large red fly and a small gilt minnow, but all the baits mentioned caught some. In following the minnow through the water, the fish would open their pectoral fins and poise themselves for a rush at it, spreading the wings also had the effect of checking their progress if their suspicions were aroused' by a near inspection of the bait. When hooked they proved very game fish, taking out several yards of line in their first rush, and often taking a flight in the air, line and all." When swimming under water the pectoral fins are held close to the body. Breeding. Eggs with external filaments as in the gar-fish (p. 146). As food. Inferior. Habitat. Atlantic coasts of Europe, but more common in the Mediterranean. A few stragglers have been captured off our coasts, but the shoals which have been recorded, but none of the members of which have been captured, may not improbably have consisted of skippers, Scombresox saurus (see p. 152). In July, 1823, a flying-fish, the species not recorded, was taken ten miles from Bridgewater (Taylor, Ann. of Phil, xxii, p. 152). Some were said to have been seen off Portland Island in August, 1825, from the deck of a vessel going down Channel (London Quarterly Journ. of Science, xx, p. 412), but none were procured. Another shoal was observed at the mouth of the Bristol Channel in August, 1876 (Taylor, Zool. p. 5128). A fine example in October, 1849, was left by the tide in Stonehouse Pool, and was, but is not now in the Plymouth Museum. R. Couch, however, remarks not rare in Mount's Bay, Cornwall, in the summer of 1845, while about five miles off shore I saw many start from the water into the air, but none seem to have been procured. One was found on the beach at Helford, near Falmouth, and given to Couch : another was thrown on to the I do not consider that as yet we have sufficient evidence to prove that shoals of these fishes approach our shores ; but rather that such as have been captured were a tew stragglers, mostly arriving singly. 156 PHYSOSTOMI. quay at Plymouth which, according to Couch, leaves no doubt as to its being 1 this species. In September, 1796, one was said to have been seen at Allonby (Heysham, Catal. Cumberland Animals). In Ireland examples have several times been observed off the south coast. 2.

The greatest height of the head equals its length anterior to the hind edge of the preopercle. Snout obtuse when the mouth is closed, rendering the dorsal and abdominal profiles equally convex. Teeth minute or absent. Fins anterior dorsal rays not half so long as the head : the fin arises above or slightly in advance of the origin of the anal. Pectoral reaches to the base of the caudal. Ventral short, about half as long as the head, and reaching half-way to the anal. Caudal lobed, the lower much the longer. Scales 6| rows between the origin of the dorsal fin and the lateral-line. Colours bluish along the back, becoming lighter on the sides and beneath. Pectoral gray or black with a light edge. Breeding. Of this but little is known: the eggs have external filaments as observed upon respecting the gar-fish (p. 146). Mr. Howard Saunders (Zool. 1874, p. 3838) says that some years since, when at the Chincha Islands, on the coast of Peru, I observed they appeared about the last week in March, and the water round the rocks was alive with them. At this period of the year, when heavy in spawn, they were not noticed " on the wing." They literally swarmed into the crevices and fissures of the rocks, and were evidently spawning. Mr. Flower exhibited at the Zoological Society, July 13th, 1858, a flying fish (Exocoetus volitans}, to which was attached a specimen of Penellus Blainvillii, Milne Edwards, 2| inches long, its head and three hornlike processes being buried in the muscular mass on the right side of the spinal column of the fish, and the whole of the exposed part gave lodgment to a colony of little cirripeds, Concho- derma virgata, Spengler. The specimen was taken in the Atlantic, about 5 17' outh latitude. As food. Of a fairly moderate description, but rather dry. Habitat. Tropical and temperate seas. It has been obtained off the Atlantic coast of France. In June, 1765, Pennant mentions an example of the flying-fish having been captured a short distance below Carmarthen, in the liver Towy, in Wales. He figures Exocoetus evolans, but does not expressly state that his drawing was from the Welsh specimen ; and Couch suggests it was drawn from a preserved example. This may be so, and it is therefore with doubt that I insert this species among the British Fauna. Couch, however, does not state that his figure was made from a British example, but he says there is no doubt but that those captured along the south coast belonged to Exocoetus volitans. The example figured is one in the British Museum collection. CYPRINID^E. 157 Family, IV. CYPRINID.E. Branchiostegals three: pseudobranchise generally present. Body oblong or elongated : abdomen usually rounded, but if compressed and cutting destitute of ossicles. Margin of the upper jaw formed by the premaxillaries Opercles in four pieces. Mouth toothless, but from one to three rows of teeth in the inferior pharyngeal bones, which latter are strong, free, and parallel to the branchial arches. A single, rayed, dorsal fin : ventrals inserted posterior to the pectorals. Head scaleless : body scaled or scaleless, never covered by osseous plates. No "cul desac" to the stomach, nor pyloric appendages. Air-bladder, if present, large : it may be divided by a constriction into an anterior and posterior portion, neither of which are enclosed by bone (Cyprininse) : or into two lateral portions, partially or entirely enclosed in a bony capsule (Cobitidinae). Geographical distribution. This extensive family includes a large number of forms distributed throughout the fresh waters of the Old World and of North America. As already remarked (page 53), in Europe and Asia it appears to take the place of the Salmonidse of the colder north, increasing in numbers as the tropics are approached, until in Asia the genera are very numerous. Some few forms are said to occasionally to be found in salt lakes, also some are stated to descend to the brackish tidal waters of estuaries, or even to the sea. Although some forms of European carps are unquestionably vegetable feeders, all are not so, the difference in their food being indicated to a great extent by the character of their inferior pharyngeal teeth, and the extent of their digestive tract. No one who has fished for the Indian barbel or mahseer (a species of Barbies), would for one moment place such among strictly herbivorous forms. We have some Cyprinidce which are omniverous, others carnivorous, insectivorous, and gramminiverous ; some which generally associate in schools, others only doing so at certain seasons, and a few that appear to be more solitary in their habits. Fatio has observed in carps in Switzerland a greater development in the first pectoral ray in the male than in the female. This is more especially the case in the minnow (Leuciscus phoxinus), which has even seven or eight thus enlarged, and not exclusively at the. breeding season. Many of the carps possess cirri or barbels on the snout or jaws, serving as organs of touch. As regards hybridism among members of the carp family, Siebold has noted as probably such the following 5 in his Fresh- water Fishes of Central Europe : Gyprinus Kollarii, between the common and crucian carps. Abramis Leuclcartii, between the bream Brama and a Leuciscus. Abramis abramo-rutilus, between a bream arid a rudd or roach. Albnmus dolabratus, between the bleak and German chub. Ghondrostoma rysela, between G. nassus and Telestes Agassizii. Researches in this country do not appear to have afforded any grounds for upholding or assailing the above. As food the carp family are not so much appreciated in Great Britain and Ireland as they are on the continent of Europe and elsewhere, probably due to our cooking being inferior, and likewise to fish not being much esteemed by the lower classes, who also prefer the marine to the fresh-water forms. Thus the despised bream, Abramis blicca, which is considered worthless with us, is made a savoury dish by Dutch cooks. Even the chub Lubbock mentions having tasted after it had been prepared by a French woman, who produced from one of these fishes a dish wherein " the scales and bones were absent, the watery taste was all gone, the flesh was firm and sweet in flavour, and altogether it might be regarded 158 PHYSOSTOMI. as a real victory achieved by the cuisiniere over stubborn materials." Perhaps the rud, if similarly treated, would meet with similar success. As it is, the chief use in Norfolk for coarse fish is to bait crab-pots or employ as manure. It has been observed that the fishes which afford the best evidence of ruminating action are Cyprinoids, as carp, tench, and bream, when peristaltic movements occur in the alimentary canal, and successive regurgitations of the contents of the stomach induce actions of the pharyngeal jaws as the half-bruised food comes into contact with them and excites a succession of swellings and subsidences of the irritable palate as portions of the regurgitated food are pressed against it. On the occiput behind the roof of the palate is a single grinding tooth or plate, which has opposed to it the two inferior pharyngeal bones armed with teeth : while in front of this plate, and forming the roof of the palate, is a thick, soft, vascular, and highly sensitive mass, which becomes thinner anteriorly, and is believed to be useful in taste, being supplied by branches of the glosso- pharyngeal nerves. This mass is commonly known as the " carp's tongue," and held in great esteem among epicures. First group Cyprininse. A. Abdomen rounded and without any compressed edge. Genus I. Ctpkinus, Artedi. Branch iostegals three : p >se ' u d branchio3 present. Body oblong. Mouth small, anterior : lips thick and fleshy. Barbels four. Pharyngeal teeth in three rows : molarform 3.1.1-1.1.3. Dorsal fin long, with its last undivided ray osseous and serrated posteriorly : anal with few branched rays (5-6). This carp is a native of temperate portions of Asia, and appears to be especially common in China in both its wild and domesticated condition. It has been imported from thence into Europe and America. Holme observes that in heraldry a carp is the emblem of hospitality, and denotes food and nourishment from the bearer to those in need. 1.

D. 21-25 ( T Vla 9 a), P. 15-16, V. 8, A. 7-8 ( a i 3 ), C. 20, L. 1. 35-40, L. tr. 5/9, Vert. 21-21/16-17. Length of head 4 to 4-f, of caudal fin 5| to 6, height of body 3 to 4 in the total length. Eye small, situated a little before the middle of the length of the head, 2 diameters from the end of the snout, and 3 apart (in an examplo nearly 17 inches long). Opercle strongly striated. The proportions of the various parts of this fish are exceedingly diverse, dependent upon age, sex, and locality. Barbels of moderate length, those at the maxilla the longest, and almost equal- ling one diameter of the orbit. Lips thick and leathery. The maxilla reaches to beneath the front edge of the orbit. Fins dorsal commences rather nearer to the snout than to the base of the caudal, its first two or three or rarely four rays are bony, the last being serrated posteriorly, while the anterior portion of the fin, which is the highest, equals about two-fifths the height of the body below it. Pectoral situated low down, its length equals about that of the head without the snout, and it does not extend to above the ventral, which latter reaches half-way to the anal. First two or three anal rays osseous, the last being serrated posteriorly. Caudal deeply forked. Scales large, 5 to 6 rows between the lateral-line and the base of the ventral fin. Colours vary, usually brownish or with a bluish tinge along the back, with golden or coppery reflections along the sides. Some have been described of a whitish tint due, perhaps, to age, others as having black spots caused, perhaps occasionally, by parasites. Varieties in form. The body in some is much more elongated than in others. Some ichthyologists observe upon the existence of a second continental species Cyprinus hollar ii or C. striatus, but which is a hybrid between G. carpio and Carassius vulgaris, having some very short barbels : it is a bony and inferior fish, and is known in some parts of Germany as the " poor man's carp." The fins are subject to modifications, being very much prolonged in some forms, as will be more particularly alluded to when treating of the gold cai'p. The chief German varieties of carp which are cultivated are : (1) The common carp : (2) the mirror-carp, or carp king, Cyprinus rex, cyprinorum, C. specularis, G. macrolepidotus, the most highly improved breed in central Germany. A small head, thick body, large scales, and tendency to rapidly grow large. In this race some pisciculturists make a speciality of raising forms with very few scales, some- times restricted to one row along the lateral-line, in others to a strip along the back. When in the water the mirror carp has its back of a bluish colour tinged with gray or greenish, but more decidedly blue than either of the other two varieties. It is said to be the most hardy form, and to bear injuries the best : (3) the leather-carp, Cyprinus nudus, C. alepidotus, C. coriaceus, or G. nudus, in which scales are absent, but the skin is very much thickened, its a well defined race and not a mirror-cai-p denuded of scaling : these are sometimes of a golden- brown colour and are very fashionable in Germany. There have likewise been various forms of monstrosities described. Names. Carp has been derived from the Greek term " kuprinos " itself said to be from " kupris " or " Cyprus," where Aprodite or Venus w r as first worshipped, and may have been given to this fish in order to symbolize its extraordinary fecundity. Holme (1688) gives Seizling as yearlings, next a sprole or sprale from two years of age, terms taken from Gesner's Swiss names of this fish, they not being called " karpf " until four years old. In (Whole Art of Fishing, 1719) the last century we are told it was called the fresh-water fox and queen of rivers. Cerpyn, Welsh. Be Karper, Dutch. La carpe, French. Habits. Hardy and tenacious of life, cautious and wary in a state of nature, but readily tamed so that it will even take food from the hand. It mostly fre- quents ponds, canals, sluggish pieces of water, or slow flowing rivers, being especially partial to localities possessing soft, marly, or muddy bottoms. It can also live in water unsuited to other fish, as the pools of bog meadows or sloughs, though the kind will be inferior. During the summer it may be seen lying among the weeds at the surface of the water, at which it lazily sucks making a very distinct noise which has been likened to that produced by a pig. Or else a number may be perceived near the surface quietly swimming about in a shoal, or returning lfiO PHTSOSTOMI. to the bottom in search of food. About November, or as winter approaches, it becomes more sluggish, and will even lie dormant in the mud into which it will probably retire along with numerous companions, or else seek its quarters under weeds, roots, or hollows. Occasionally it is found alive in muddy bottoms of ponds almost destitute of water. Carp, says Hessel, during the winter are huddled together in the mud in concentric circles with their heads together, the posterior part of the body raised and held immovably, scarcely lifting the gills for the purpose of breathing and without taking a particle of food. Though it does not feed or grow during its winter sleep when in its natural retreat, it does not diminish in weight : but while kept in large tanks or winter chambers it falls off in a remarkable degree. It will not thrive in overstocked ponds, while owing to its muddy flavour when transferred direct from such places to the kitchen it is found advisable to retain it for some weeks in a stew, through which a supply of water flows. Here it will feed well and fatten. Jesse says that his were very fond of boiled potatoes. It can also be kept for a long time in well-boats through which water is allowed to pass, and may be thus conveyed long distances. It is partial to the shoots of aquatic plants, succulent vegetables, worms, and the larvae of insects, while occasionally it will make a mouthful of a small fish. Mr. Gurney (Zoologist, 1860) observed a carp devour three young minnows each about 1| inches long which were confined with it in the same tank. It will not despise the refuse of kitchens, slaughter-houses, breweries, or even the excrements of cattle and pigs. One reason given for permitting pike in carp ponds is that the latter fish are apt to become languid and lazy, whereas a few pike would give them exercise, inducing them to seek their natural feeding-places. But as a rule pisciculturists prefer their absence. Pennant observes upon the following experiment having been twice made, of placing a carp in a net well wrapped up in wet moss, the mouth only remaining out, and then hung up in a cellar or some cool place : the fish being frequently fed with bread and milk, and often plunged into water. Thus treated it has been known to live above a fortnight,* and grow very fat as well as lose its muddy taste. It can be sent alive very long distances packed in moist moss with a mouthful of bread steeped in brandy and occasionally renewed. In the Horti- cultural Gardens, South Kensington, the stock of carp was found to be too great for the vegetation, so 300 averaging fully 2 lb. each and the greater part full of spawn, were transmitted in wet moss to the Colne, near Haresfield, and did not appear to suffer from the journey (Field, April, 1881). Three carp averaging 10 lb. each, were sent from Windsor Park at 7 A.M. to the Southport Aquarium, arriving at 8 p.m., they were packed in damp moss in a hamper. On being placed in a tank two immediately swam away, the third appeared exhausted at first, but shortly recovered and did as well as the other two. Means of capture. The fisherman finds this fish an adept at escaping from nets, by burrowing below it, or springing over the corks, consequently to have carp completely at command there should be means of letting off the water in which it resides, either partially or entirely. So difficult is it to net that unless some such provision is made one can well understand the Norfolk fen-men regarding it with mysterious awe, how its entrances and its exits into pieces of water puzzle them, and how, as Lubbock remarks, they consider it as something more than a fish, and look upon it as what the Scotch term " no cannie." In angling for this fish various plans have their advocates, but all agree that as a rule the carp is exceed- ingly wary and difficult to capture. The best time in the day for sport appears to be early in the morning or late in the evening : bright days are inauspicious as it swims near the surface but does not feed, while should there be a cold wind it seems to be somewhat dormant and refuses the tempting bait. Warm cloudy days, with a tendency to rain, appear to be those best suited for angling for carp. A fine line with a quill float should be used, having a light weight (as a shot) about a foot from the hook, and good strong rod, while the depth should be plumbed so that the shot finds rest on the bottom. The rod should be fixed into the bank and the * In Holland it has been said they are thus kept afire in cellars for months ! CYPRINID^E. 161 angler be out of eight keeping quite quiet, while he must not strike at the first symptom of a bite, bat wait until the float begins to move away. Baits. Many are in vogue, as a paste of bread crumbs, to which may be added honey and gin. Blue-bottle flies, ripe cherries, green peas boiled in sugar, grains, balls of green silk-weed so common in ponds, worms, green gentles, grasshoppers, larvae, small red worms from dry earthy dunghills rolled into a ball. In the Cherwell, near Oxford, the common carp is far from being a shy fish, and seems to have a peculiar affection for the red and white paste of the roach fishermen (G. F. Field, Sept. 1882). Mr. Jardine (Field, Dec. 11th, 1880) records the capture of a 9j lb. carp, with a small artificial dace. A correspondent of the same paper (Dec. 4th, 1880) remarks how using a large yellow Thurso salmon-fly in order to try and take a pike in a pond, he caught a carp of 4 lb. and hooked two others, the fly being only six inches below the surface. Breeding. A carp is supposed to commence breeding at three years old, returning yearly to the same spot, and during its migration it has been known to spring several feet out of the water in order to overcome obstacles. Some are either temporarily or permanently sterile. But, of those which breed, one of 9 lb. had 600,000 eggs (Bloch) ; one of 16| lb. had 101,200 ova, another of 25| lb. 203,109 ova (Harmer) ; one of 21^ lb. 1,310,750, another of 16^ lb. 2,059,750 eggs (Buckland). Hessel found a fish weighing from 4 to 51b. contains on an average 400,000 to 500,000 eggs : in the somewhat larger-bodied scale-carp he generally observed comparatively more eggs than in a mirror carp of the same age and weight. It generally spawns about May or June, in accordance with the nature of the season, and one female attended by two or more males may be observed on warm days among the aquatic weeds where the adhesive eggs are deposited. Some continue extruding ova for several weeks or even months, interruptions occurring during cold or rainy weather, while others may retain it occasioning disease. During the breeding season it is readily taken as it appears to lose all fear. After spawning it returns to the water it usually resides in. During the spawning season numerous wart-like protuberances appear upon the skin of the head and back of the males, disappearing after the expiration of that time ; while some little time prior to this period the pharyngeal teeth are shed and which are yearly renewed. The eggs develop quickly should the weather be propitious, the eyes showing themselves as early as the fifth or sixth day, and on the twelfth or sixteenth day at the furthest, hatching commences in shallow and warm ponds. After a certain number are in a pond they cease to increase ; perhaps the parents devour their eggs or their offspring. Hermaphrodites. Jacket (Abh. ntr. Ges. Nurnburg, 1867, iii, p. 245) describes one and likewise (Fische Bayerns, p. 21) gives an account of some hybrids, between a variety of the common carp (Carpio macrolepidotus) and the crucian carp (Carassius vulgaris), and which he terms Carpio Sieboldii, a form almost valueless as food. Pennant mentions hybrids between the carp and tench, and having also heard of some between the carp and the bream. Bloch observed that the carp produced hybrids both with Carassius auratus and C. gibelio. Hessel observes that he placed a female common carp with a male crucian carp, also a female crucian carp with a male common carp, and a female Cyprinus kollarii(see page 159) with a male of the common carp. In the two first cases the young became identical with C. kollarii, some approaching more towards one parent, some towards the other ; while in the last experiment the product was with difficulty to be distinguished from the genuine carp. He fed these last for three years in order to try their fitness for the table, but they were poor in taste, very bony, and could not be compared by any means to the common carp. Life-history. The carp attains to a good old age. Gesner refers to one of a hundred years, and Buffon to another of one hundred and fifty. Buckland observes that in Windsor Park the fishermen informed him that a carp in a certain stew must be nearly one hundred years old ; how this was ascertained is not recorded. In Germany and other countries where this fish is cultivated, it is found that if May is mild and warm the greatest increase of growth 11 102 PHYSOSTOMI. occurs : it appears only to grow during four months, or from May until August inclusive. Respecting their rate of growth it differs in accordance with the water inhabited, as to if such is warm or cold, a river, lake or pond, the supply of food, quality of the soil, and the race of carp. Under favourable circumstances they will attain from 3 to 3 lb. weight in three years. In warm climates carp have been known to attain from 2f to 4 lb. in one year, which increase would take two- and-a-half years in colder regions. In 1865 some ponds in Windsor Park were run dry, and the carp in the obelisk pond were of a very similar weight from 4 lb. to 6 lb., the head fisherman Wheeler asserted they were at least fifty years old : they had been twice removed within his memory from different ponds, the last time about thirty-five years' previous from a pond near Cumberland Lodge when they weighed about 3 lb. each. In the Royal stew two brothers and sisters to the foregoing were larger, one turning the scale at 10^ lb. (Fish. Mag.). They may become gradually white with age. Diseases. Is subject externally to fungoid growths, especially old carp ; also the same moss-like appearance occasionally attacks young fish which reside in foul or snow water, as well as blindness, epidemic fevers, visceral obstructions due to over-gorging on chickweed, ulcerations of the liver, malignant pustules under the scales termed small-pox by fishermen, carbuncles, and intestinal worms. It appears to be very susceptible to electric influences. On fishing a pond in Dorsetshire a great number of carp were found, each with a frog mounted on it, the hind-legs clinging to the back, the fore-legs fixed in the corner of each eye of the fish, which were thin and greatly wasted (Pennant). Williams (Brit. Angler, 1740) observes, when many carp have been put into a well-watched pond so that they could not have been stolen, at the emptying three or four years subsequently, not a carp would be found. This, he says, is attributed, and in all appearances justly, to their being destroyed by the frogs. The Rev. A. Lloyd (Liverpool Standard, March, 1835) states, that, when engaged with a garden rake in clearing some decayed wood and leaves out of the water of a pond, he brought a live trout, about 6 inches long, to land with a large frog firmly holding it, grasped tightly round the middle. In 1880 it was stated that, during the draining of Count Schaafgotsche's carp ponds at Warmbrunn, it was observed that frogs were clinging to the backs of many of the larger fish, most of which, thus beridden, being blind, the frogs' fore-feet being firmly fixed in the eye sockets of their victims. Hessel observes that once during his absence a number of large carp were fed upon coagulated blood which had commenced to putrefy ; the fish devoured it eagerly, became ill, and most of them died in a few days from inflammation of the intestines. Spoilt food should never be given to fish. Frogs appear to be inimical to the eggs and, perhaps, the very young fish, while dabchicks and other water-birds are destructive to the fry. As food. In some countries, especially in those where eating fish forms a portion of the religious creed of the people, this fish is largely cultivated, while a supply is kept in stews, so that when fast or feast days come round it is readily available ; they were, likewise, very useful in times when the means of carriage was slow. It is not much esteemed in this country owing to its muddy flavour, but this it loses if kept in a stew through which a stream flows. The best tasted forms are those from rivers ; next, such as come from large lakes ; and the most inferior taken direct from muddy ponds. Carp is in season from October until April. The palate, commonly termed " the tongue," is considered a delicacy. Its roe is converted into red caviare by Jews in Italy and Eastern Europe as, by their law, they may not eat caviare made of sturgeon, that being a fish destitute of scales. To improve their flavour Mr. Tull (Phil. Trans. Roy. Soc. 1754, p. 870) castrated these fish and found that subsequently they grew more rapidly, fattened more readily, and were of a superior flavour. Habitat. This fish, which is indigenous to Persia, China, and contiguous countries, even to Java and other islands in the Malay Archipelago, has been CYPRINID^E. 163 introduced into and widely disseminated in the temperate parts of Europe and Asia. It appears to have been cultivated in Germany and France as early as 1258 ; introduced into Sweden in 1560, and into Denmark in 1660, and is now found from Italy to Sweden and Norway, and from France to Russia and the boundaries of Eastern Siberia. A considerable number are taken in the Black Sea and Caspian ; and Nordmann remarks upon their presence in the salt lakes of New Russia. Among the older writers Cassiodorus, of the sixth century, terms the Garpa of the Danube a costly fish of delicate flavour and supplied to the table of princes. When this fish was first introduced into England is involved in obscurity ; it is not alluded to in the Anglo-Saxon Dictionary of ^Elfric, who, in 1051, died Archbishop of York. The first mention of it seems to be in Dame Juliana Berners' Boke of St. Albans, published in 1496, wherein she speaks of the carp as " a dayntous fysshe, but there ben but fewe in Englonde, and therefore I wryte the lesse of hym." About 1514 * Mascall is said to have introduced it into Sussex, probably extending its range. The Rev. J. Hughes, of Meltham, observed that he had read most of the works of the Welsh poets, from Aneurin down to the last century, but in none had he found the Welsh name for the carp. The doggrel lines of " Turkeys, carp, hop, pickerel and beer Came into England all in one year" may be considered interesting as verses, but not faithful representations of facts. It appears to be absent from the Orkneys, and is not so common in Scotland as it is in England, where it is found in lakes, ponds, canals, railway ponds and rivers throughout the country. It is especially fine in some of our eastern counties, as in Yorkshire and the Norfolk broads. It was formerly said not to be found in Cornwall, but is now present there. Moore observes upon its absence from the Isle of Wight. In Ireland it has been noted in County Down, Armagh, Galway, Sligo, Kilkenny and Dublin, and said to have been introduced into the south by the great Earl of Cork. Rutty observes that this fish was acclimatized in Ireland during the reign of James I (a.d. 1603 to 1625). The example figured is a female full of roe which died in October, 1882, while in transit from Buckinghamshire to the Royal Westminster Aquarium. It is 16'8 inches long, and for it I am indebted to J. Carrington, Esq., F.L.S. As to the size these fish attain in this country, that varies with localities, one over 20 lb. appears to be a very large one. One was taken at Sheffield Park in 1882 which weighed 19 lb. (Field, November 18, 1882) : on emptying the lake at Bay ham Abbey, near Lamberhurst, in July, 1870, one was secured weighing 21 lb. 10 oz. (Coombe, Field, November 25, 1822) : Yarrell exhibited one 30 inches long and weighing 22 lb. at the Zoological Society, November 22, 1836, it was taken in the Mere, near Payne's Hill, Surrey : in the autumn of 1858, the great pond at Harling, near Petersfield, was fished, and a carp of 24| lb. taken (Gordon, History of Harting) : in Holland 20 lb. fish are not rare, while in the German lakes they attain to 40 lb. or 50 lb.f * Dr. Giinther places the date a century later, observing, "the year 1614 is assigned as the date of its first introduction into England " (Introduction Study of Fish, p. 590), or 118 years subsequent to the date of Dame Juliana Berners' work wherein she tells the reader how to catch it by angling in this country. f In 1711 one was said to have been dragged from the Oder, near Frankfort, 9 feet long and 3 deep, and weighing 76 lb. : Jovius alludes to another from Lake Como of 2001b. weight ! 11 * 1G4 PHYSOSTOMI. Genus II. Carassius, Nilsson. Branchiostegals three : pseudobranchia?. present. Snout obtuse and rounded. Mouth anterior, arched, and rather narrow : lips thin. No barbels. Pharyngeal teeth compressed and in a single roiv, 4/4 (JDentes scalpriformes, Bonap.). Dorsal fin commencing opposite the ventrals, having many rays (15-25), its last undivided one being osseous and serrated : last undivided anal ray osseous and normally serrated. Scales of moderate size. Lateral-line continued to the base of the caudal fin. The two species of this genus found in Great Britain are possibly merely the eastern and western representatives derived at a remote period from a common ancestry : the Carassius vulgaris being more essentially Western Asiatic and European, while the G. auratus is of Chinese and Japanese extraction. Very similar in external appearances, it is likewise remarkable that the latter, of which I possess specimens from near Yunam, in China, are of the same green colour in rivers as the wild European form. The C. vulgaris generally has a more elevated body, and from 31 to 35* rows of scales along the lateral-line, while the gold carp has usually from 25 to 30 rows. Both, however, are subject to almost innumerable variations as to proportions, while they are likewise somewhat intimately related to the common carp, Cyprinus carpio, with which they inter- breed, to the deterioration of the breed in carp fisheries. 1.

Length of head 4| to 5, of caudal fin 4| to 51, height of body 2\ to 4 times in the total length. Byes in the anterior half of the head, diameter of each from 5 to 6 in the length of the head, 1 to \\ diameters from the end of the snout, and 1^ to 2 apart.

Barbels absent, if present which sometimes occurs, the example is thought to have been crossed with the common carp (see G. kollarii). Teeth, pharyngeal normally 4 4, but in some I have found 4, 2 or 3 2 or 3, 4, and scalpriform having somewhat compressed crowns with a depressed and flattened surface. Bins the dorsal commences on a line above the insertion of the ventrals and ceases above the termination of the anal : it is higher in some examples than in others, its last undivided ray is serrated posteriorly. The last undivided anal ray osseous and posteriorly serrated. Caudal may be cut almost straight posteriorly, simply notched or almost forked. Colours vary, generally brownish tinted with green along the back : brown or gray tinged with yellow on the sides and white or yellowish white beneath. Fins dark with a bluish or red tinge. Varieties. The Carassius vulgaris is the highest variety of this species, in some the shape of its body being* almost quadrangular, and the dorsal profile much more elevated than the abdominal. The gibele differs in the less height of the body, being somewhat starved in appearance, and is not so deep and more carp-like than G. vulgaris, having a blunter head, longer lower jaw, back not so elevated, and the caudal fin more deeply forked. G. moles, C. V, is a form having a low dorsal fin, and G. oblongus, Heckel and Kner, one in which the body is elongated. The G. Icollarii, known by the presence of barbels, is a hybrid between the common and crucian or gold carp, already referred to (p. 159). It is chiefly raised in the neighbourhood of Paris and Metz, also in Belgium, and is a very inferior fish. I have obtained an example, a little over seven inches in length, from Kent, the pharyngeal teeth in which are 4/4. Names. Crucian or Prussian or German-carp. Also termed Hamburgh carp, probably from its having been disseminated from that town or the place where it was best known. Grouger, Warwickshire. Byrbysg, Welsh. Be steenharper, Dutch. Le Carassin commun, French. Habits. Much the same as those of the common carp, is an indolent fish, which keeps much to the bottom, coming to the surface when there is a warm sun. It is very tenacious of life. Yarrell instances one which survived after having been kept thirty hours out of water. It lives in localities wherein the impurities are sufficient to destroy most other fish : it is said to thrive in the Thames. In Scandinavia it appears to like shallow, muddy, or grassy lakes. And it is asserted that this fish when put into water with a muddy bottom does not acquire a bad taste so soon as the pike, perch, and other piscine forms. Means of capture. Netting. A well scoured brandling is recommended as a good bait, but this fish seldom bites freely. Breeding. April, May, and June. Depositing its ova among aquatic weeds at this period, and congregating in shoals. As food. Said to be good in Sweden and Russia, but is generally considered inferior, tasteless, and bony. Habitat. Europe and Siberia, but it is doubtful whether it is indigenous to this country or has been introduced. It is now generally distributed throughout 166 PHYSOSTOMI. favourable localities in this country. It is very common about London and in pieces of water in tbe vicinity of the Tbames. In Ireland it is mentioned as existing by Thompson. The example figured is seven inches long, from Kent. Tarrell observes that he obtained a crucian carp in October, 1824, which weighed 21b. 11 oz. 2. Carassius auratus, Plate CXXX, fig. 2.

The proportions in this fish show great anomalies. Length of head 4 to 4, of caudal fin 4 to 5, height of body 2f to 4 times in the total length. Eyes diameter of each from 4 to 5 times in the length of the head, 1? to li diameters from the end of the snout, and the same distance apart. Snout obtuse, cleft of mouth shallow, and the jaws anteriorly of about the same length. Barbels absent. Pharyngeal teeth 3 or 4/4 or 3 in one row, and similar in form to those of Carassius vulgaris. Fins similar to C. vulgaris except that the dorsal fin is generally a little higher. Colours various. As already remarked, those living in their native streams are similar to Carassius vulgaris. In a domesticated state it may be red, vermillion, rose-coloured, pink, white, silvery, sometimes with black marks, while the same tint does not invariably pervade the whole of the fish. If turned out into the open its brilliancy generally decreases. During the first year of its life it is usually black ; next mottled with silver. This last colour spreads over the whole fish, and after one or two seasons gradually becomes of a red or brilliant tint : in some they are coloured from the time of their birth. Varieties. This fish, due to domestication, is subject to great structural alterations : the vertebral column alone may be deformed but the fish be otherwise perfect ; the dorsal fin may be entirely absent or reduced to one spine and a few rays, the fish being otherwise perfect ; or with a reduced extent of dorsal fin the anal spine may be double. The caudal fin may be enlarged and divided into three or four lobes, the length of which may be nearly equal to that of the remainder of the fish, while at the same time the dorsal fin may be present or absent. Occasionally the eyes are protruding, forming what are known as the CYPRINIM;. 167 telescope goldfish, and this may he conjoined to a three or four-lobed tail fin. Sir R. Heron (Proc. Zool. Soc. 1841, p. 42) remarks respecting his menagerie that two out of five of the specimens of gold-fish hatched are deficient of the dorsal fin, and about two in a hundred, or rather more, have triple tail fins, and as many have the anal fin double. All the deformed fish are separated from the others, and placed in a pond by themselves, but they do not produce a greater proportion of deformed offspring than the parent fish. As already observed, the Garassius auratus in its wild state is greenish. It may assume a yellow colour termed leaccethiopism or xanthochroism : or a red colour, erythrism : or a white colour, albinism : or black, melanism ; and these changes are not invariably produced by the same causes. The temperature of the water in which they reside influences colour, gold denoting the warmest, as from 80 to 88, and here they increase most rapidly, while bronze or silver is the tint most observable in those that are kept in the open air. In an account of the mode in which one of the gold-fish breeding establishments at Oldenburg is carried on, the correspondent remarks (Land and Water, May 3rd, 1879) that for the purpose of inducing colour the three chief materials needed are iron, gall-nuts, and tan. A fish originally red and white can by proper treatment be rendered black, white and red ; but some fail, and these are consigned to a large shallow pond, where they are more exposed to the sun's rays, which have a strong colouring influence ; but the treatment is somewhat hazardous, often killing the fish, and that quite suddenly. Names. Gold-fish: Gold carp. Eurbysg, Welsb. Le Carassin Dore, French. Habits. Much the same as the crucian, but more domesticated. In manu- facturing districts, where there is an inadequate supply of cold water for the condensation of the steam employed in the engines, recourse, observes Yarrell, is had to what are termed engine-dams or ponds, into which the water from the steam-engine is thrown for the purpose of being cooled ; in these dams, the average temperature of which is about 80, it is common to keep gold-fish ; and here it multiplies very rapidly, and becomes useful in consuming the refuse grease, which by accumulating on the surface would impede the cooling of the water. It appears to thrive upon insects, but if it is found necessary to supplement artificial fare, blood and refuse meat, worms, or even barley are recommended. Kept in confinement, well or pump water seems to suit it the best, and only in emergencies should stream or river water be employed, while rain-water is quite unsuitable. Breeding in May or June. In breeding, many influences exercise an effect upon this fish, thus Thompson observes that " in some ponds near Belfast this species bred the first year of its introduction ; in others not for several years ; and in one the fishes have never increased. The temperature of the water in the first was warmest, and in the last coldest." As a general rule the gold carp does not spawn in transparent vessels ; it requires ponds in which the bottom is not too smooth and where there are weeds suitable for its purpose. In the almost stagnant water of the breeding ponds at Oldenburg, should a little invigorating of the fish be deemed necessary, augmented aeration is found to have this effect, and after receiving a current of aerated water it frequently begins to spawn within an hour's time ; by stimulating, a considei*able proportion of the fish may be made to reproduce their species when not over twelve months of age. While bv high feeding, frequent distribution of the parent fish (the same males and fern, les not being allowed to " keep company " long together), and occasional aeration of the water, it is found possible to pre-arrange the dates of spawning almost to a day, and also to raise a large crop from a comparatively small breeding stock. The first brood is raised in March or April, the second in July or earlier, and the third about the end of August or commencement of September. Many thus stimulated become prematurely barren, but even when comparatively less stimulated it is the exception to use the fish as spawners more than two years. M. Carbonnier (Compt. Rend. 1872, p. 1127) has recorded how he has observed the male of the telescope variety acting as accoucheur to the female. Three 168 PHYSOSTOMI. males pursued one of the other sex which was heavy in Bpawn, and rolled her like a ball upon the ground for a distance of several metres, and continued this process without rest or relaxation for two days, until the exhausted female (who during this period had been unable to recover her equilibrum for a moment) had at last evacuated all her ova. Mr. Waddington, of Bury (Hardw. Sc. Gossip, 1876, p. 278) instances a pair of gold-fish, kept in an inverted propagating. glass, which commenced breeding August 27th, the male pursuing the female with the greatest fury, rubbing against its sides, and at times almost pushing it out of the water. The eggs were laid singly or two or three adherent together, and the male devoured them with the greatest avidity. The eyes in the eggs appeared on the third day and they hatched on the eighth. At Oldenburg, the fry ordinarily attain by the autumn 1^ to 2f inches in length, and if properly coloured the largest are saleable for globes. The gold carp will cross with the common carassin and probably with the common carp. Diseases. When at Oxford, in the warm months of 1880, Mr. W. Hatchett Jackson showed me some gold-fish affected with the parasitic infusorian Ichthioplrfhirius multifilns of M. Fouquet. Other fish from the Isis had previously been observed to be similarly affected, and doubtless in many instances of reputed recovery from Saprolegnia ferax, the fish had really been suffering from the above parasitic infusorian. Owls have been observed to be destructive to these fish (Mag. Nat. Hist, i, 1829, p. 179). Habitat. A native of Japan and China, its lively and vai'iable colours, its curiously modified forms, and its generally interesting habits have caused it to be kept in glass vases, fountains, and pleasure grounds in many parts of the world. It is now spread throughout Europe, and not only flourishes domesticated but also thrives in ponds and suitable pieces of water. The year in which they were first introduced into England is uncertain and has been stated as 1611, also 1691, but were said to have been destroyed, consequently the fish was not generally known, according to Pennant, till 1728, when a great number were brought over and presented first to Sir Matthew Dekker, and by him circulated round the neighbourhood of London. The earliest seen in France are said to have been sent to Madame Pompadour. A correspondent of Loudon's (Mag. Nat. Hist, iii, p. 478) suggests that gold carp were probably introduced into Portugal at an early period, after the people of that country had discovered the route to the East Indies by the Cape of Good Hope, as they appear to be now completely naturalized there. Having lived some years at Cochin, on the Malabar coast of India, and investigated the fishes, I must demur to this, as the gold carp is not found wild in any part of India, and I have never even seen it domesticated on the Malabar coast. It grows to about 10 or 11 inches in length in this country, but in China attains a much larger size. CYPRINID^E. 169 Germs III. Barbus, Cuvier and Valenciennes. Puntius, pt. Ham. Buch.

This most extensive genus has been variously subdivided, and possesses most diverse and interesting forms, which, in British India, Burma, and Ceylon, number at least seventy species. But as in the British Isles we merely possess one species, the reader, if desirous of information respecting the above, must be referred to my work on the Fishes of India, pp. 556-582. Geographical distribution. Europe, throughout Asia and Africa. These fishes are omnivorous in their food, while some forms attain to a very large size ; thus the Mahseer or Mahaseer of India, Barbus tor, Ham. Buch., has been captured more than once over 100 lb. in weight, but such must be considered very exceptional examples. Barbels from clear streams in India, when not above 10 or 15 lb. weight, are excellent eating, and deleterious effects do not, as in the British species, follow employing them as food, but some forms of Indian hill-carps as certainly are unwholesome, although it would appear that by constant use the individual who eats them as food becomes no longer amenable to their injurious influences. 1.

Length of head 4 to 4, of caudal fin 4|, height of body 5 to 6 times in the total length. Eyes rather high np, situated in the middle of the length of the head, 8 to 10 diameters in the length of the head, 3 to 4-| diameters from the end of the snout and 3 to 4 apart. Dorsal profile more convex than that of the abdomen, which is almost horizontal. Snout produced and somewhat overhanging the jaws, the maxilla much longer than the mandible. Lips thick. Barbels two thick pairs, the maxillary ones extending to beneath the middle of the eye, while the rostral pair are somewhat shorter. Teeth-Pharyngeal curved, hooked at their extremity and pointed, 4, 3, 2/2, 3, 4. Fins dorsal com- mences about midway between the angle of the mouth and the base of the caudal fin, the extent of its base j shorter than the third undivided dorsal ray, which is the longest, osseous, strong, and serrated along its posterior margin : last ray of the fin half the height of the longest anteriorly. Pectoral inserted low down, broad, and about 4/5 as long as the head but not reaching the ventrals, which latter do not extend to the anal. Anal narrow, the length of its base being only 2/5 of its height. Caudal deeply forked. Scales about 35 rows anterior to the base of the dorsal fin, and 7 between the lateral-line and the base of the ventral. Lateral-line complete, continued to the centre of the base of the caudal fin. Gill-rake'rs short. Colours olivaceous shot with gold, lightest along the sides and lower surface. Dorsal fin with a narrow, dark outer edge. The other fins of a reddish colour. Steindachner (Verh. z. b. Ges. Wien. 1866, p. 385) considers Barbus Mayori, Cuv. and Val. from the Lake of Zug, to be this species : he also notices the supposed hybrid between Barbus and Chondrostoma. Names. Barbel, from "barba," a beard, or the "bearded fish." Barfbyfg y Barfog, Welsh. Be Barbeel, Dutch. Le Barbeau, French. Habits. The barbel generally prefers the bottom of still rivers and their deeper parts, where they live together in schools, rooting in the soft banks with their snouts like swine or turning over gravel and other movable substances under which they search for suitable food. Some delight in rapids below weirs, others are partial to shallows where there is a good stream, and they will even lurk under weeds. During the season of 1880 these fish were rather numerous in the open tideway at Hammersmith. The barbel is not very timorous and roves about at night-time, while it consumes both animal and vegetable substances. An old writer observed that it " delighteth in filth, speciallie in the dung of beastes, as Oppianus among other matters reporteth " (Angler's Note-book, p. 151). It consumes worms, grubs and small fish. When in an aquarium it is often shy, but this is not invariably the case. It is said to be a long-lived fish. As winter sets in and weeds die off they hybernate or congregate together in large numbers under the lee of a sunken boat, below banks and in deep pools, at which periods they are readily netted or poached by snatching. They are said to have been taken by persons diving after them. Under water they are able to produce a sort of guttural sound without occasioning any bubbles to rise. It is a matter of history that subsequent to a dreadful carnage between the Turks and Austrians on the banks of the Danube, barbels were found of such vast size and in such numbers as to become a subject for record, while their propensity for human flesh being well known, the circumstance was attributed to the heaps of dead bodies which had been thrown into the river. Means of capture. The angler requires strong tackle and a fair amount of patience, but it is evidently an occupation that has many votaries, as may be seen along the Thames in the proper season, especially during September and the earlier part of October, where punt-fishing for barbel is indulged in. The angler cannot be at work too early in the morning or too late in the evening for these fish, which are most particular in their choice of food as such must be sweet or they will reject it, and even then they will try and suck off the bait. It is best to ground-bait the locality to be fished some hours prior to commencing to fish, and in doing this the article employed should be of similar kind but inferior in quality to that which is going to be employed by the angler. When hooked the barbel is strong and dashes towards any cover, as a post in the CYPRINID^E. 171 water, a bank or other suitable place and is not unlikely, unless well handled, to break the line, for its leathery mouth affords a secure hold for the hook. Baits. Lobworms, greaves, green gentles, cheese, caddis worms, &c, it will bite at bees, while this fish is not unfrequently taken in the Thames by anglers spinning for trout. Breeding. It spawns in May and June, depositing from 7000 to 8000 ova on the gravel, and which are subsequently covered over with great care by the parent fish. In warm seasons the young hatch from the tenth to the fifteenth day. Bloch believed that the barbel does not breed until towards its fourth or fifth year. Having spawned, the spawners make for the swiftest piece of water they can find, and within a few weeks begin to recover condition again. These fish grow very rapidly. Uses. Isinglass is said to be made of its air-bladder in the Volga, a statement possibly, if not probably, erroneous. Yarrell observes that the barbel in the coat of Bar, forms one of the quarterings of the arms of Margaret of Anjou, Queen of Henry VI, the founder of Queen's College, Cambridge. As food. Not held in esteem, being very coarse. Ausonius tells us that when it grows old it is not absolutely bad. If so, this is exactly contrary to what occurs in Asia, where the old fish are tough, oily, and strong flavoured. Some poor people are said to employ them as food, having boiled them with a piece of bacon to give them a relish. The roe, when eaten, occasionally, but not invariably (as proved by Bloch), is found to be poisonous. It used to be taken by the country people to induce a purge and a vomit. Sir J. Hawkins observes that the flesh of this fish set up most dangerous choleraic symptoms in one of his servants in 1754, so that he nearly died. Gesner asserts that his life was endangered from eating its flesh. Dame Juliana Berners remarked that, " The barbyll is a sweet fysshe, but it is a quasy meete and perryllous for manny body . . . and yf he be eten rawe he may be cause of manny dethe : whyche hath oft be seen." Badham advises its being boiled in salt and water and eaten cold, after having had a squeeze of lemon juice over it, and he states it to be by no means despicable fare. Its best season is from when it has recovered after breeding until September or October, when frosty weather drives it to its winter quarters. The Jews, having boiled them with vinegar and oil, eat them not only during their White Feasts, but whenever they can obtain them. Bloch therefore, who was a Jew, may be excused for considering it a prejudice rejecting them, although he remarks their flesh is white and of good flavour, and the eggs he has eaten, besides giving them to his family, when not a single person among them was incommoded. That barbel in some localities are good eating is well known (see page 169), but it appears as certain that they are deleterious in other places, while some persons may consume them with impunity, whereas they would be poisonous to others. Habitat. Large rivers in the temperate and warm latitudes of Europe, attaining to a considerable size, as 40 or 50 lb. in the Rhine and in the Danube. Absent from Scotland and Ireland, although it obtains a place in Brown's Catalogue. It is somewhat restricted in its distribution in England. In Yorkshire it is found locally in the rivers of the central plain, except the Derwent and the polluted waters of the Aire, Calder, Dearne, and Don (Yorkshire Vertebrata). It is largely taken at Sheffield. It is abundant in the Trent and in the Thames, but absent from the Severn, although it is asserted that this fish in the time of Queen Elizabeth was one of the forms in the latter river protected by legislation ; consequently, if it existed, it must have died out, as I cannot hear of it there now. Pennant gives its Welsh name. I have already observed that it has been taken in the open tidal waters off Hammersmith, and it is numerous in the Thames from Putney upwards. The example figured is 16 inches long, from the Thames, for which I am indebted to Mr. T. Carrington, F.L.s. As to the size this fish attains in this country Jenyns mentions examples up to 2 or 3 ft. long. In 1860, one which weighed upwards of 10 lb. was killed at Richmond. Yarrell observes that the largest fish he could find recorded weighed 15 lb., while a 19 lb. fish is said to have been taken from the Lea in Essex. 172 PHYSOSTOMI. Genus IV. Gobio, Cuvier. Pseudobranchioj present. Body more or less elongated. Mouth inferior, upper jaw slightly the longer ; when the mouth is open the lower jatv does not project beyond the upper : lips of moderate thickness. A small maxillary barbel at the angle of the mouth. Pharyngeal teeth in two rows, hooked and pointed at their extremities, 5 or 4, 2 or 3 3 or 2, 4 or 5. Dorsal fin short, with few rays (9 10), all of which are articulated. Anal with few rays. Scales of moderate or rather large size. A lateral-line present. The fishes which belong to this genus are naturally feeders on animal substances, but they do not, therefore, invariably refuse vegetable food. 1. Gobio fluviatilis, Plate CXXXI, fig. 2.

Eye high up, in or slightly behind the middle of the length of the head, diameter 4f to 5 in the length of the head, If to 2 diameters from the end of the snout, and 1| apart : interorbital space flattened. Dorsal profile much more convex than that of the abdomen, which is nearly horizontal. The proportions of this fish are subject to great modifications in accordance with the localities it inhabits, the seasons, &c. Body compressed, becoming more so in its caudal portion. Snout somewhat obtuse. Upper jaw the longer, the maxilla does not extend so far posteriorly as to beneath the front edge of the orbit. Barbels one at the maxilla usually reaching to below the middle of the eye, but liable to variations in length. Fins dorsal commences about the centre of the length of the fish excluding the caudal fin : the length of its base nearly equals half its height : its first ray minute, its third, which is undivided, 4/5 the height CYPRINID^E. 173 of the body below it, from thence they rapidly diminish in height, the last being only half that of the third. Pectoral inserted in the lower fourth of the body, as long as the head without the snout, and rounded at its extremity, it does not extend to as far as the ventral, which latter is still slightly shorter and does not reach the anal. Anal commences in the last third of the distance between the angle of the mouth and the base of the caudal fin : its anterior portion nearly twice as high as its last rays : caudal deeply forked, with pointed lobes. Scales large and the exposed portion angular. Lateral-line continuous to the middle of the base of the caudal fin : tubes simple. Pharyngeal teeth rounded, curved and pointed at their extremities, 4, 2/2, 4. Colours olive along the upper portions of the head and back, becoming silvery on the sides and beneath. Upper portion of body with numerous irregular brown spots and dark edgings to the scales, and in the young a row of dark spots cross the lateral-line ; but in large specimens a wide silvery band runs along the side of the body mostly above the lateral-line : a dark mark under the eye and a few black spots in the pectoral region. Dorsal fin with several irregular rows of black spots, and similar ones exist on the lobes of the caudal fin most distinct externally. Young examples are darker than adults and more blotched and spotted : a line of spots runs across the anal fin while the ventral is dark tipped : opercle nearly black. Names. " Gudgeon " is a corruption of the French term Goujon. As gudgeons are an easy prey to even the most inexperienced angler, the common expression "to gudgeon a man" is said to have its origin from this cause. Gogeon (Diet. 1593), googen (Diet. 1608). Blcege, Anglo-Saxon. Crothell, Welsh. The word gudgeon is often used synonymously with "an untruth," or for a joke or taunt. " To swallow a gudgeon " is often employed for being made a fool of: "to gape for gudgeons " to mean to look out for impossibilities. An old term was river smelt. Be Gmndel, Dutch. Le Goujon, French. Habits. A small, gregarious river fish, selecting places where the current is not too strong and the bottom is sandy or gravelly : or else a pond through which a stream flows, while it keeps near the bottom : generally during the day-time the gudgeon seeks the shade becoming more active towards nightfall. During the warm months found in or near shallows but returning to the deeper water in winter. In some years plentiful, in others just the reverse. It will live in very polluted water, even at the mouths of drains, localities in which the more cleanly fish, as trout, would inevitably succumb. In Aquaria it is fond of reposing motionless for hours in one place. While it thrives, observes Newman, on the impurities of London water alone. It eats worms, insects, small fry, ova, and some plants, but is a capricious feeder, subject apparently to some atmospheric influences. Fishmongers are able to keep them alive for some weeks in stone or leaden- lined tanks, provided there is a good supply of cold water. Mr. Gosden, of Exeter, recorded having found one of these fish 7% inches in length among some herrings taken at Cloverley, which would seem to show that stragglers may occasionally descend to salt water. M. Valenciennes subjected some of these fish to the following experiment. He placed them in water below the bell of an air-pump, and gradually reduced the aerial pressure. When this was diminished to half or a quarter the fish suffered little, and few air-bubbles escaped. When the reduction of pressure was rapid and carried far, many bubbles escaped ; and when the mercury stood very low, the gas in their inside expanded, the belly became blown, and the fish floated on the surface, its back being downwards. Such examples were found to have the air-bladder quite empty. They continued to live, and when replaced in water at the ordinary atmospheric pressure, they resumed their normal position after about twenty-four hours, but remained quiet at the bottom, with the abdomen quite hollow. Slowly their original form and bulk returned, and in six hours their air-bladder was again filled, the contents of which, on being tested, were found to be azote. Means of capture. Although the gudgeon bites all day from the end of March until Michaelmas, the months considered best for this species of fishing are during August, September, October, and sometimes the commencement of 174 PHYSOSTOMI. November. The locality chosen is usually from four to six feet of water, where the stream is only of medium strength, while the bottom should be sandy and free from weeds. It seldom bites in cold weather, or just subsequent to a flood, or in the dark ; but during the sunny hours of the warm months delights to lie in the shade, as under a plank or boat, while it is by no means shy. It is assembled in shoals by raking the bed of the river, which, setting free desirable food, causes numbers to flock to the place. A small hook should be employed ; with some a very light line is used, while others consider a moderately heavy one better or the extent of the swim is reached too rapidly, whilst floats are dispensed with in some instances. Occasionally it will suddenly cease biting from some unascertainable cause, or it may be the effect of a scare produced by a pike or perch having appeared on the feeding ground. In the cold weather when it retires to deeper water, the line should be leaded so that the hook touches the bottom. Baits. A small red worm. Breeding. April, May, and June, depositing its small bluish ova among stones and in the shallow water of streams, the ova, according to French pisciculturists, requiring about a month to hatch. Yarrell found fry about an inch long in August. In some localities they are supposed to breed three times in the year, or to take a long time spawning. Mr. Manley found that some placed in a pond multiplied there although the bottom was clayey. Uses. As baits, for perch fishing or on night-lines for eels. As food. Much esteemed, easy of digestion, and never out of season if procurable. That from the Thames is considered by some to be far superior to the same fish from other rivers. The following plan has been recommended : take a frying-pan in the boat when gudgeon fishing. Clean, wipe, and let the fish dry until it is almost hard by hanging it out in a wind or exposing it to the sun ; then fry it in boiling fat, butter, or oil till crisp and of a light brown colour. Dr. Brookes (Hist. Fish. 1772, p. 113) asserts that it is tender and delicate, and by many swallowed alive, being thought good for a consumption. Thompson alludes to an instance of a dog in the river Lagan which was accustomed, when the water was low (about nine inches deep), to search for, catch, and eat gudgeons. Eels are very partial to these fish. Habitat. Northern and temperate parts of central Europe, extending from Denmark to France and Italy. Some skins of this species exist in the British Museum obtained from Parnell's collection are now labelled Scotland. As the species is not alluded to in his work they may be from elsewhere (see vol. i, page 311). In Yorkshire it is common and generally distributed in rivers and ponds (Yorkshire Vertebrata) : also in Lancashire : in Norfolk very scarce among the broads (Lubbock) but abundant in the higher parts of the rivers where it finds gravel shoals. The finest gudgeons are found in the Trent, Kennet, Thames and Colne, those from the last three growing to a large size, but fine ones are not unfrequently taken in the Wye, while it is generally found in suitable pieces of water. It has only of late years been known in Devonshire, having been probably introduced : a specimen was captured by Mr. King, June 3rd, 1873 (Parfitt) : I have already alluded to one from Cloverley. It is said by Couch to have been introduced into Cornwall and thriving in some ponds near Penzance, but Mr. Cornish remarks that he does not know of it (Cornish Fauna). In Ireland, noted in county of Antrim, Dublin, Kilkenny. In the Barrow, the Shannon Canal, Tuam and Headfort. Templeton observes that these fish appeared in the River Lagan in 1801 having ascended the canal from Lough Neagh where they have been inhabitants, perhaps, for centuries. Introduced from Dublin into the River Dodden about 1822 by an angler who, living in Dublin, disliked the trouble of going so far for bait : 1852 it had become common, often attaining ten inches in length (Kinahan). The example figured life-size was captured in the Thames in October, 1822, by Mr. T. Carrington, f.l.s. This fish does not usually attain to above eight inches in length, but Pennant alludes to having heard of one half-a-pound weight having been taken at Ux bridge, a weight which some modern authors have doubled. CYPRINID^E. 175 Genus V. Leuciscus (Klein), Cuv. and Vol. Phoxinus, Agassiz : Scardinius, Sgualius, and Telestes, Bonap. : Idus, Leucos, Heckel : Pseudophoxinus, Bleeker.* Pseudobranchice present. Mouth anterior, lips of moderate size. Barbels absent. Pharyngeal teeth compressed or conical, in a single or double row. Dorsal fin with few rays (9-14), all being articulated, it commences nearly or quite opposite the ventrals : anal also with few rays (9-15). Caudal forked or emarginate. Scales of large, medium, or small size, covering the body. Lateral-line complete or incomplete. Intestinal tract short, having only a few convolutions. The old-world forms belonging to this extensive genus have been subdivided into several smaller genera by various ichthyologists, in accordance with the character of the pharyngeal teeth, and whether they are in one or two rows : the position of the dorsal fin and the number of the anal rays : the number of scales along the side of the body : and whether the lateral-line is complete or incomplete. Of the indigenous British species we possess the following : Pharyngeal teeth in a single row : Leuciscus rutilus, D. 11-13, A. 11-14, L. 1. 42-45. Teeth in a double row: L. cephalus, D. 11, A. 11-12, L. 1. 42-46 : L. vulgaris, D. 9-10, A. 10-11, L. 1. 48-52: L. erythrophthalmus, D. 11-12, A. 13-15, L. 1. 40-44: L. phoxinus, D. 9-10, A. 9-11, scales small and lateral-line incomplete. Geographical distribution. These fishes are widely distributed throughout Europe and the northern portions of Asia and North America. As a rule they are exclusively found in fresh water. 1.

Eyes situated very slightly above the centre of the height of the head, the diameter of each 3^ to 4 times in the length of the head, 1 to 1 diameters from the end of the snout, and 1^ apart. Body somewhat elevated and compressed. Mouth anterior, the jaws of nearly equal length, and the cleft of the mouth a little oblique ; the maxilla reaches to beneath the posterior nostril. Teeth pharyngeal teeth in a single row 5 or 6 6 or 5 (only 4 are said to be present in some examples), in some the left side has one more than the right. They are somewhat hooked and pointed at their extremities, but become ground down with age. Fins dorsal, commences midway between the end of the snout and the base of the caudal fin, its height anteriorly being one- fifth more than the length of its base. Pectoral as long as the head, excluding the snout. Ventrals inserted on a vertical line beneath the first ray of the dorsal fin ; they are slightly longer than the pectorals, but do not reach to the anal, the length of the anterior rays of which latter fin are a little longer than the extent of its base. Caudal deeply lobed, the length of the central rays being about two-fifths of that of the longest outer one. Scales 4 rows between the lateral line and the base of the ventral fin ; about 17 rows anterior to the base of the dorsal fin. The abdominal edge, between the base of the ventral and the insertion of the anal, somewhat compressed, but not sharp. Lateral-line slightly concave anteriorly above the base of the ventral fin, and situated between the middle and lower third of the depth of the body. Pseudobranchiae moderately developed. Colours superiorly bluish or greenish, becoming lighter on the sides and beneath. Lower fins reddish-yellow, in some localities red ; dorsal and caudal dusky, with blackish outer margins. Varieties. Several have received distinct names owing to the proportions of the body differing, some being more elongated than others, this variation being often due to size or else to the colours being pale or otherwise unlike the typical form. Names. " Sound as a Roach," is a proverb that appears to be but indifferently founded, that fish being not more distinguished for its vivacity than many others; yet it is used by the French as well as us, who compare people of strong health to their Gardon, our Roach (Pennant). Some have asserted that the proverb was as "sound as a Rock" and the old Roche Abbey shows that the ancient mode of spelling "rock" was "roche," while Ray gives it as "sound as a trout." Sometimes termed red-dace from the colour of its fins. Mr. A. Walker informs me that at Chester this fish is termed Roach-dace. Rhyfell, Welsh. Braise, Scotland. Scylga, reohha, reohche, heoce, Anglo-Saxon. De Blank-Voorn, Dutch. Le Gardon commun, French. In heraldry three roach are borne in the arms of the De la Roche family. Habits. A gregarious fresh-water fish, preferring clear and deep but still rivers and quiet waters, and although, observes Parnell, the sea is not the natural abode of the roach, yet sometimes it is found there, being carried down from rivers and lakes after high floods. He saw five examples, taken from the salmon nets in the Solway Firth, in the month of June, and stated that they are frequently taken there after a flood. But that this migration must be very gradually effected the following observation from Montagu would seem to show. A small river in CYPRINID^). 177 Devonshire ended in a large piece of water or lake, nearly two miles in extent, close to the sea, bnt having no outlet except by percolation through a barrier of shingle ; here roach throve and multiplied exceedingly. One year the sea broke its boundaries and flowed copiously into the lake at every tide for a considerable time by which every species of fish therein was destroyed. As the cold weather sets in, as about October, the roach seeks the deeper waters where a gravelly or sandy bottom is preferred to a muddy one. Means of capttbre. This fish is capricious respecting biting, although Dame Juliana Berners observed, " the roche is an easy fysshe to take," and later still Isaak Walton tells us that it was accounted the water sheep for its simplicity and foolishness. But now, in some localities at least, it has been educated to be more careful of the tempting bait. The angler must employ, in the Thames or Lea for instance, fine tackle, be careful as to his depth, the bait in a river being about 3 inches from the bottom, but less in a pond, while he must be an adept in striking sharply but not violently, on a bite occurring, use a small hook, have a quick eye and nimble hand. In ponds it is often more ready to take a bait than it is in rivers, the following account is taken from a newspaper: An angler baited a spot at about 5 p.m. on Saturday in August, in Herefordshire, with gentles and wasp grubs, and again on Sunday at 3 p.m. On Monday morning, at 4 a.m., he was in his punt at the spot and baited with wasp grubs, and fished about one inch from the bottom. The fish bit ravenously : at 12 the sun came out brightly and they ceased biting : he had then 241 fish (Field, Sept. 2nd, 1882). As the frost kills aquatic weeds then the anglers opportunity is at hand, for as the roach loses this form of food it becomes less shy in taking a bait. Baits. The tail of a lob worm, a bit of bacon fat, gentles, pastes of various kinds, and prepared greaves, boiled wheat and brewers' grains, while ground baits are generally employed. Although it rarely takes a live bait, one weighing 1| lb. was thus captured by a paternoster baited with a live minnow at Pangburn, November 27th, 1882 (Field), and the editor of the Field observes that he has taken the roach once or twice in the same way. It will also occasionally take a fly. Roach preserved in spirit are said to do well as bait for winter trolling. Breeding. A very prolific fish, the eggs of which are greenish but become red on being boiled. About the middle of May or in June it commences ascending to the higher portions of rivers or side streams to breed : its scales become rough and it is usually out of season. Buckland found 480 eggs in one of 28 oz. weight. In some years this is accomplished earlier. Thus, in the Thames, in 1881, the ascent for this purpose was observed at the end of April (Field, April 30th). At a meeting of anglers held in Birmingham, April 4th, 1881, it was generally agreed that in the Trent this heading up had not been seen before the middle of May. In Norfolk it generally resorts to a river for the purpose of breeding, or selects a situation intermediate between one and a broad but to which it is united by a main dyke. At that time, remarks Lubbock, the roach crowd together in such dense multitudes along the rushes which fringe the bank that every instant one sees small ones raised momentarily half out of the water by the passage of a larger roach. These fish appear to lose all fear in the overwhelming instinct which prompts them to propagate their kind, and may be scooped out in numbers with a landing-net : if a bow-net is put in they will crowd in until the centre can contain no more. Nilsson remarks that the males precede the females in these annual migrations. But the eggs themselves are subjected to great destruction. Thus, it has been observed near Uxbridge that at spawning time the roach actually cover the weeds near the weir, while water shrimps and other insects come down upon them and in a very short time clear them almost entirely away (Buckland). Having spawned, the roach seeks swift parts of rivers and gravelly shallows to recover itself, which does not take very long (about a fortnight), and it soon retires to quieter quarters. Hybrids. Various fishes upon the Continent of Europe have been believed to 12 178 PHYSOSTOMI. originate hybrids with the roach. The first I shall allude to is said to he the bream, Abramis brama, forming Cyprinus buggenhagii, Bloch, and which has been taken not only in England bnt likewise in Ireland. There is, however, one little but insuperable difficulty in this identification of Dr. Giinther's (Catal. vi, p. 214), which is, that as the roach* does not occur in Ireland it is difficult to see how it could form a hybrid there with the bream, rendering it much more probable that if the form is a cross it is between the rudd and the bream, to which I have therefore referred it. Another cross is believed to occur between the roach and the rudd, the Tieuciscus affinis C. V., or Scardiniopsis anceps, Jack el, and which has been found in France and Bavaria. D. 13, A. 14-15, L. 1. 40-42. Origin of the dorsal fin rather more posterior than in L. rutilus, the pharyngeal teeth deeply serrated, 5-5 or else 5 or 6, 1 or 2 1 or 2, 5. A hybrid is likewise considered to take place between the roach and Abramis blicca. A. 14-18, L. 1. 43-46, L. tr. 8|-10f/7. Pharyngeal teeth in one or two rows. This form has been observed in Holland, Belgium, and Germany, and it is difficult in some examples to decide whether the Abramis brama or A. blicca can be considered the form which has crossed with the roach. As food. Coarse, flabby and insipid, consequently is but rarely eaten. It is in the best condition about October, and when taken from clear water flowing over a gravelly bottom : some have recommended it baked in layers in a pie dish, with intermediate bay leaves and a little spice. Habitat. In most rivers in temperate portions of Europe. Generally through Great Britain, but absent from Ireland, where the Rudd, L. erythrophthalmios, takes its place and has been recorded as this species. Early in May immense shoals are observed to leave Loch Lomond and ascend tributaries to breed. This lasts about three days, and anglers remark that during this brief period not a trout can be taken, either with the minnow, worm or fly as they gorge themselves with the roe of the roach (Ure). Also found in the Union Canal, near Edinburgh (Wilson). A fresh-water resident in Yorkshire, abundant and generally distributed, except in the North- Western Fell district and the polluted rivers, from which it is absent. Has been introduced into canals, reservoirs, and ponds (Yorkshire Vertebrata). It is common in streams and broads in Norfolk (Lowe), and generally distributed throughout Great Britain. In Devonshire it is found in the Exeter canal, some ponds by the South Devon Railway, and Slapton-Ley Lake, while it is very abundant in the River Axe (Parfitt) : it is absent from Cornwall (Cornish Fauna). Although it is rare to capture one of these fish over 2 lb. weight, one of 2 lb. 12| ounces was taken by Mr. Stead in Bedfordshire in 1881 (Field, Nov. 2nd, 1881). The largest observed by Jesse in the Thames was 3 lb. weight, while Pennant remarks that a London fishmonger informed him of one which weighed 5 lb. 2. Leuciscus cephalus,t Plate CXXXII, fig. 1.

They bred there last year, 1882, for the first time since their introduction, and although they may at some future date be properly included in a British Fish-fauna, they can scarcely be so at present, as they are not yet found in a wild state as are some other acclimatized foreign forms.

Eyes diameter of each h\ to 6 times in the length of the head, 2 diameters from the end of the snout, and 3 to 4 apart. Snout obtuse. Mouth rather deep, the upper jaw slightly overlapping the lower, and the posterior extremity of the maxilla reaching to beneath the front edge of the eye. The hindermost bone of the suborbital ring the largest. Teeth pharyngeal teeth pointed and hooked at their extremities (in some slightly denticulated), 5, 2-2, 5. Fins the dorsal commences midway between the end of the snout and the base of the caudal fin, its height exceeds by one-third the extent of its base. Pectoral as long as the head excluding the snout. Ventral inserted on a line slightly anterior to the origin of the dorsal fin, its length equalling about half of that of the head. Lateral-line slightly concave, 3 rows of scales between it and the base of the ventral fin. Colours mudd} r bluish or greenish colour along the upper surface of the head and body, becoming lighter on the sides and beneath. Dorsal and caudal fins dusky or greenish and externally dark; ventrals and anal bluish white tinged with red. Cheeks dashed with red and gold. Navies. In several languages the size and width of its head appear to have furnished materials for its name, chub being derived from the Anglo-Saxon term copp, "a head." Large-headed dace; loggerhead. Shelly in the north having reference, it is said, to the large size of its scales, while it is also suggested it may be a modification of skully, referring to its head. Chevin and chevenden, possibly from the French " chef," a head. Penci and Cochgangen, Welsh. Le Ghevaine commun ou Meunier, French. Habits. Frequents deep holes in the more rapid rivers, preferring a sandy, gravelly, or marly bottom. During the summer months, after recovering from 12 * 180 PHYSOSTOMI. spawning, as in July and August, it appears to delight in lying on the surface beneath the shade of a tree or bank, while it is very sensible to atmospheric changes. It is exceedingly timid, sinking to the bottom on the least alarm, even on observing a passing shadow, but soon returns and re-occupies its former situation. In October, as the weeds die off, it retires to deeper water, as under willow beds, or wherever it can obtain good shelter. It feeds on vegetables, worms, caterpillars, grasshoppers, beetles, and insects which happen to fall into the water. It will occasionally eat small fish and rise to a fly. Means of capture. Rod and line, chub fishing being greatly in vogue with some anglers. Extreme caution is necessary, as it possesses very quick vision, and even the shadow of the rod will scare this fish, but it generally returns again to its former position, and the fisherman is able to throw his large fly, dab his cock- chafer or grasshopper, or sink his caterpillar, when it will rarely be refused. During the summer months the mornings and evenings are best suited for this description of fishing, but in the winter it will take a bait during the middle of the day. Once hooked, due to its leathern mouth, this fish is usually secured. Baits. Gentles ; a cockchafer impaled on an arrangement of double hooks ; a worm ; a grasshopper ; a moth ; a large artificial fly and even the loach ; a young frog ; skin of beef ; cheese ; a black snail. Red cherries, used in clear streams, is one of the best baits, especially for large fish ; also blackberries ; it Avill take many berries, particularly strawberries. Breeding. It commences about the end of April or beginning of May, selecting a shallow locality under weeds, and where the bottom is gravelly. After spawning it passes to the swiftest streams, when it soon recovers its strength and becomes fit for the angler. Hybrids have been recorded between this species and the bleak. D. 11, A. 13-16, L. 1. 45-54. Height of body 4f of that of the total length; 3 rows of scales between the lateral-line and base of the ventral fin. As food. Coarse and bon} r , with little, if any, taste, while it rapidly decom- poses. Is said to be best broiled with the scales on. Dame Juliana Berners observes, " the chevyn is a stately fysshe ; and his heed is a deyty morsell." Diseases. Among the Lernese, Tracheliastes polycolpus has been found on the fins of one of these fish. Habitat. Throughout most of Europe and extending into Asia Minor. It is found in the Annan and other rivers of the south of Scotland : but absent from the north, as well as from some parts of the west of England. It is found in Cumberland, in the Caldew and its affluents. In Yorkshire it is abundant, and generally distributed in the fresh waters ; it is absent from the rivers of the north-east, and from the polluted portions of those in the manufacturing districts (Yorkshire Vertebrata). In Norfolk it is totally unknown in the Bure, Yare, and the Waveney, except, perhaps, in their higher portions. Is present in the Ouse, Thet, and the Wissey near Stoke Ferry (Lubbock), the Cam, the Thames, the Severn, and most Welsh rivers, and generally distributed through England. It becomes rare in Devonshire, and does not find a place in the Cornish Fauna. It appears to be absent from Ireland. The example figured is 14 - 8 inches long, from the Severn at Shi'ewsbury. One of 3 lb. 10 oz. is recorded (Field, August 13th, 1881), which was choked in its endeavour to swallow a rat of about half a pound weight. Pennell observed upon one of 5 lb. 5j oz. weight, which measured 21 inches in length. It has been said to grow to 7 lb. weight in this country, and considerably larger in the waters of the continent of Europe. 3. Leuciscus vulgaris, Plate CXXXIII, fig. 1. Vandoise, Belon. p. 314.

Length of head b\, of caudal fin 5|, height of body 4f in the total length. Eye situated slightly above the centre of the depth of the head, diameter \ of the length of the head, 1 diameters from the end of the snout and also apart. Suborbital ring of bones narrow. Body oblong and somewhat elongated, sides compressed. Cleft of mouth rather shallow, the posterior extremity of the maxilla reaching to almost beneath the front edge of the eye, lower jaw shorter than the upper. Teeth pharyngeal somewhat hooked at their extremities, 5, 2 2, 5. Fins dorsal commences about midway between the front edge of the eye and the base of the caudal fin, the length of its base equals about two-thirds the height of the longest undivided ray, which equals three-fourths of that of the body below it ; its last rays half the height of its front ones ; upper edge of fin concave. Pectoral inserted in the lower fourth of the depth of the body, as long as the head excluding the snout, and pointed, it does not extend much more than halfway to the base of the ventral, which latter is inserted on a vertical line beneath the first few rays of the dorsal and does not reach the anal. Front edge of anal in the commencement of the last third of the distance between the front margin of the eye and the base of the caudal fin, the length of its base equals three-fourths of the height of its front rays. Caudal rather deeply forked. Scales four rows between the lateral-line and the base of the ventral fin, where 182 PHYSOSTOMI. an angular one exists. Lateral-line slightly concave, continued to the centre of the base of the caudal fin. Colours bluish along the back, silvery-white upon the sides and beneath. Dorsal, pectoral, and caudal fins tipped with black : the ventral and anal have merely a slight tinge of red or yellowish. Varieties. Shaw described the graining, G. Lancastriensis, as differing from the dace, and subsequently Yarrell and Thompson have identified examples which they have captured as pertaining to Shaw's species. Yarrell in his figure places the insertion of the ventral fin on a line anterior to that of the dorsal, the latter being identical with what obtains in the dace, which the figure otherwise resembles, and with which Yarrell's examples now in the British Museum agree. Thompson's were several very small individuals taken near Leamington, where the dace abounds. In August, 1831, Yarrell obtained a fish 6^ inches long in the Thames below Woolwich, which he considered to be the Squalius dobula, and although the single specimen appears to have been lost, the figure is that of a dace with the ventral fin advanced as shown in the figure (but not in the example) of the graining. Other varieties have been observed on the continent of Europe. Names. The term dace appears to be a corruption of some older word. Bart or dare due to its rapid dart-like or arrow-like motion. In Gesner's time it was termed dard and if we turn to Ray (1713) we find he terms this fish dace or dare. Mr. A. Walker informs me with reference to the names of fishes in Cheshire that " the dace here is invariably called by the common people ' the grayling,' the roach being called the roach-dace," and suggests whether the name graining has arisen from this. Barsen and Golenbysg, Welsh. Be Serpeling, Dutch, he Ghevaine Vaudoise or dard, French. Habits. An elegant river fish, quick of vision, readily alarmed, and rapid in its movements ; it is of a gregarious disposition and delights in clean water. It is not so common as the roach, which it much resembles in its habits. The dace is even found descending to the brackish tidal waters of the Thames at Hammer- smith Bridge, and Yarrell appears to have secured a specimen opposite Woolwich. In the winter it retires to deeper water than it frequents in summer and often selects localities under shaded banks. It feeds upon worms, insects, and their larva?, as well as vegetable substances. Means of capture. It rises freely to the artificial fly, especially about August, and when hooked makes a gallant fight : the angler should strike at once on the occasion of a rise or bite. Numbers are taken bottom fishing, a worm, particularly a bright red one, being used as a bait, this is extensively carried on in the Thames during September or October up to January. Baits. Flies, gentles, red worms, grasshoppers, paste, malt. As these fish are'comparatively small feeders, a large quantity of ground bait is undesirable. Breeding. Commences the end of May or during the month of June, while it is a very prolific fish. It deposits its eggs at the roots of aquatic plants, under stones, and in the gravelly beds of rivers. It does not again regain condition before the middle or end of July. In Devonshire " large numbers of this fish are killed by the poisonous alkaline ' waste ' let off from the Countess Weir paper mills. Hundreds of them strewed the banks of the river near and below the bridge on May 31st, 1866 ; and from information I received on the spot, it appears to be a very rare thing that any other kind of fish is killed by this ' waste.' The ' waste,' it would seem, is lighter than the water, and floats and does not mix freely with it. My informant told me that the other fish took advantage of this and sank to the bottom, or swam under the ' waste,' for it was an exceedingly rare thing to find either roach, trout, or salmon killed by it. I examined a great number of the dead fish, and found them to be all dace ; I could not find a roach or perch among them " (Parfitt, Fauna of Devon, p. 21). Uses. Being a very bright, silvery fish, it is a good bait trolling for pike or lurch, especially if the water is at all thick ; while for night lines it is in demand as being tenacious of life. As food. Not held in any repute ; irrespective of being soft in flesh, it is full of CYPRINID^E. 183 bones ; it is best during September and October. The Jews are said to consume numbers, as well as of other species of white-fish, Leuciscus, during their fast months. Habitat. Most of Europe, except Italy. Not found in Scotland, but is in England and Wales; is present in the Thames, Severn, Wye, and most of our clear and rapid streams. It is common in Yorkshire, except in polluted rivers and mill streams (Yorkshire Vertebi'ata) . In Norfolk it " is abundant in the higher parts of the rivers, but does not affect the broads or the nearly stagnant parts of the rivers in the vicinity. Is plentiful in a small stream which divides the parishes of Rockland and Claxton, near JBuckenham ferry; but does not appear to quit the brook for the wider waters of the Yare " (Lubbock). It is abundant in rivers along our southern districts as in Devon- shire (Parfitt), and common in the Tamar and its tributaries (Cornish Fauna). Absent from Ireland. This fish attains to about 12 inches in length in the Thames, but is seldom found above 1 lb. weight. Very fine ones are taken in the New River. 4. Leuciscus erythrophthalmus, Plate CXXXIII, fig. 2.

Cleft of mouth shallow, the posterior extremity of the maxilla reaches to below the hind nostril. Snout somewhat overhanging the mouth, the lower jaw very slightly the shorter. Teeth pharyngeal 4-5, 2-3 | 2-3, 4-5, the sides of some of the crowns of the teeth serrated. Fins dorsal situated upon the highest portion of the back, it commences midway between the nostrils and the base of the caudal fin, the length of its base equals 2/3 or 3/4 of the height of its anterior rays, which are rather more than twice those of the last : upper edge of fin concave. Pectoral inserted low down and reaching two-thirds of the distance to the ventral, which latter, situated beneath the anterior dorsal rays, extends more than half-way to the commencement of the anal. Anal situated in the last fourth of the total length excluding the caudal fin ; the length of its base equals 3/4 of that of the longest ray, while the anterior portion of the fin is twice as high as the posterior. Caudal rather deeply forked. Scales three or four rows between the lateral-line and root of the ventral fin. Lateral-line continuous to the centre of the base of the caudal fin. Colours silvery, darkest along the back, and glossed with gold. Dorsal, pectoral, and caudal fins orange, with black tips : lower fins yellow. Eyes red. Those from deep waters are coloured very similarly to roach or dace, this fish being subject to considerable variations in tints. Varieties. It has been held by Izaak Walton and many other anglers that this fish is a hybrid between the bream or carp and the roach. The azurine was added to the list of British fishes, some fish of this variety having been obtained from Knows! ey. It is less bright, its abdomen silvery, and its fins white. Mr. Pennell found in some ponds near Romford, in Essex, a lemon or yellow-coloured variety of the rudd. Names. Rudd, pronounced Roud in Norfolk, and rudd said to be diminutive of ruddy or red : " The Red eye," finscale, Oxfordshire (Beesley) : shallow (East). Rhuddgoch, Welsh. De Ruisch-Voom, Dutch. Le Rotengle, French. Habits. Not rare in many rivers, canals, lakes, and ponds throughout the level countries of England. It has been asserted that where rudd exist roach are almost invariably present, whereas the converse does not always hold good. In Norfolk it is often found along with the Roach, but as a rule the rudd prefers the broads, and the roach the rivers. It lives on the larvae of insects, worms, small molluscs, and vegetable substances ; is very lively and active, and rises at flies and sports on the surface. Means of capture. Bites freely. Baits. These are similar to those which are useful for the roach, but paste and gentles are most generally relied on. Dr. Norman, in Norfolk, recommends a nice red worm, while the finest fish are taken with a salmon-gut line, and three hooks, a large float, and at least forty yards of strong light line. Breeding. April and May, among weeds in ponds, and is very prolific in almost every kind of fresh water : in rivers it frequently ascends for breeding purposes, and after spawning repairs to appropriate shallows, especially if the bottom is gravelly, where it scours and subsequently repairs to quieter parts of the river. Hybrids. Between this fish and the rudd have been alluded to (page 178) ; also between the rudd and the bream (page 177). Uses. Said to be the best fish for stocking new-made waters with bait for pike, which prefer them to bream or roach. On the broads they are considered the best bait for perch, although in the rivers a gudgeon is superior. As food. It is said to be preferable to the roach or bream, its flesh being firmer. Habitat. Although widely distributed, this is somewhat a local fish. It is most common in rivers of the north of England or in Scotland (Donovan). In Yorkshire abundant in ponds in Holderness. Reported as in Lake Somerwuter and in ponds in other parts of the county, also in the Codbeck. A few have been caught in the Ouse at York (Yorkshire Vertebrata), the Witham in Lincolnshire, and Cherwell, in Oxfordshire (Pennant): common in broads and rivers of Norfolk (Low T e): Thames and waters near London. In the Cam, where it is termed shallow : Isle of Wight (Moore) : Devonshire, where in Slapton Ley they breed in enormous numbers CYPRINID^E. 185 and attain a considerable size, Ireland, from north to south of the island, chiefly in lakes and slow rivers. It is probably found in every connty possessing- suitable localities.

Dr. Moreau finds the lateral-line in some instances continued on one (the left) side to the base of the caudal fin. Manley alludes to a golden coloured one caught at the mouth of the Gadd, near Rickmonsworth. 186 PHYSOSTOML Names. Anglo-Saxon, Myna. It appears to have numerous designations. Mennam in the north of England, and Mennawe and Menuse in old MSS. Minnow said to be derived from " minimus " or minute. Ray says a pink or minima or minnow-pink, so called from its colour. Locally known as Bennick or Binnick, Minim and Peer, Somersetshire ; Jack Barnell, Warwickshire (see Gasterosteus aculeatus, vol. i, p. 241) ; Meaker and Mengy, Devonshire ; Mennard, Gloucestershire ; Shabrid, apud Halliwell. Crothell y dom and Bychan byog, Welsh. Le Vairon, French. Habits. This pretty and active little fish is not often found near the sources of streams, as in such localities a sufficiency of food is not always present. During the summer months it keeps together in large assemblages and generally in shallows or near the surface. But in the cold winter months it more or less conceals itself, commencing to feed in the rivers about March and April. In the Severn and other rivers which it frequents, the minnow during the summer months may usually be found lying among the weeds at the tail of a ford, and it is captured by placing a net below these spots and treading these fish out. It feeds on aquatic plants, worms and animal substances. Yarrell observes that no one has succeeded in preserving it beyond three years in an aquarium. Cooper crossing a brook saw from the footbridge, at the bottom of the stream what had the appearance of a flower, and which consisted of an assemblage of these fish, their heads all meeting in a centre and their tails diverging at equal distances. The object which attracted them was a dead minnow which they seemed to be devouring. Means of capture. Netting, or with hook and line. Baits. A worm, or gentle, or even paste. Breeding. Very prolific, and breeding about the end of May or commencement of June, at which period the head is usually covered with small tubercles. The ova are said to be adherent together among the interstices of stones in brooks where they have been deposited. In Devonshire, after the month of June, when most of them have finished spawning, Parnell observed that the males ascended the shallows in large shoals, occupying sometimes the space of several feet in circumference, and giving the water an appearance with their little white-spotted heads of a bed of Ranunculus aquatilis before the buds have fully expanded. Yarrell records having taken the young f of an inch long by the first week in August. Davy found that they hatched on the sixth day. Fatio has observed (Arch. Sc. Nat. lii, 1875) that not only is there an enlargement of one pectoral ray in the male during the breeding season, but from 6 to 8, and not confined to one period but continuous more or less throughout the year. Uses. Excellent as bait for eels or as spinning bait for trout, perch, pike, or even chub, when it is generally hooked through the upper lip or back fin. Some anglers keep these fish in a white earthenware jar instead of in bottles or tin cans, as they seem to remain much brighter. Although they afford excellent sustenance to trout it is questioned whether they ought to be kept in large numbers in waters frequented by young salmonid, as both forms devour the same kind of food and thus the minnow might starve young trout. As food. Much esteemed dressed as " Whitebait." William of Wykeham, the founder of Winchester College, at a dinner which he gave the King and Queen and 210 guests, on September 16th, 1394, had served, among other fish, seven gallons of minnows, which cost lis 8d. Habitat. Disseminated throughout Europe. In Scotland, near the Moray Firth, " abundant in the Isla, near Keith, and in some other tributaries of the Deveron " (Gordon) ; streams near Banff (Edward) ; one in the Glasgow Museum from Lanarkshire is 4 inches long; Aberdeen (Sim). Throughout most of the north of Scotland, becoming more plentiful as we advance south, in all the rivers entering the Firth of Forth, but rare in the Teith about fifteen miles from Stirling (Parnell). In England the minnow is found in the lake district, and Mr. Eagle Clarke observes that he caught about a dozen of the largest he ever saw in the stream running into the Wastwater ; they were quite seven inches in length. Yorkshire CYPRINTDJB. 187 abundant up to 1250 feet elevation ; in Norfolk it shuns stagnant water, but is plentiful in the rivers above Norwich but does not often occur below that city. Throughout most of the streams, canals, and in many ponds of England and "Wales, especially in rivers with gravelly bottoms, and found as far as Cornwall, but said to be absent from the Isle of Wight. Ireland. Scarce w T here calcareous rocks predominate, while in Scotland, where the water is very free from calcareous matter, the minnow is common. Several localities in counties Down and Wicklow. In fact, it is a very local fish in that island and rare in many districts. Introduced into the Dodder from Dublin about 1822 (Kinahan) ; and Dr. Ball mentions one 6 inches in length taken in a pond at Glasnevin Gardens near Dublin ; also that when he was at Lough Dan in Wicklow in 1846, a fisherman informed him he had been there twenty- five years (1821) and that they were as plentiful when he came as they were now. Professor Ernst Friedel has stated that at Dublin (1879 or 1880) he " was struck by the thousands of minnows, Leuciscus phoxinus, the more so as this fish has only of late years been introduced into Ireland, and is as yet only found in the rivers of Dublin and "Wicklow." The figure is from a specimen taken in Hampshire. It attains to as much as 6 or 7 inches in length but is rarely seen above 3 or 4. 188 PHYSOSTOMI. Genus VI Tinca, Guvier. Pseudobranchiai 'minute. Mouth anterior : lips thick hut destitute of any horny covering. Barbels 2, one at either angle of the mouth. Pharyngeal teeth in one row, 4s or 5 | 5 or 4 cuneiform, ivith a slightly hooked extremity. Gill-rakers short and lanceolate. Dorsal fin rather short, commencing slightly behind the origin of the ventral; anal short : caudal slightly emarginate : scales small, embedded in a thick skin and covered with mucus. Lateral-line complete. Geographical distribution. Fresh waters of Europe and of Asia Minor. The tench has been said to have been introduced into England about the year 1514, but tbere does not appear to be any decisive evidence that it is not an indigenous species. It has been acclimatized in the waters around Ootacamund on the Neilgherry Hills in Madras, where it is thriving (Day, Fishes of India, 1878, p. 594). 1. Tinca vulgaris, Plate CXXXIV, fig. 2.

Eyes diameter 6| to 1\ times in the length of the head (but comparatively larger in the young), 2 diameters from the eud of the snout, and from 2 to 2-j- apart. Interorbital space flat. The thickness of the head equals its length excluding the snout, while its height equals its thickness. Snout obtuse, mouth anterior, jaws anteriorly of the same length, gape wide, cleft rather shallow ; the posterior extremity of the maxilla reaches to beneath the hind nostrils. Lips thick. Teeth pharyngeal, in a single row, 4 or 5/5 or 4, sometimes 4 on one side and 5 on the other. Gill-rakers short. Fins dorsal commences above the end of the base of the ventral, and is continued almost to above the origin of the anal : all the fins are rounded. In the males the first or even more of the ventral rays are thicker than in the female, as will be alluded to. Scales about 18 rows between the lateral-line and the base of the ventral fin. Lateral- line at first gradually descends and above the base of the ventral is continued to the centre of the base of the caudal fin. From the thickness of its skin it is termed the "shoemaker" in Holland. Colours leaden or greenish, lightest beneath ; fins blackish. Yarieties. The golden tench (variety aurata) merely differs from the common form in its colours, which may be simply yellow or red, either without or conjoined with black spots or blotches (variety maculata). These forms are now extensively propagated in this country. Mr. Berney, of Merton HalJ, Norfolk, in 1852, imported this variety of the tench from near Breslau, in Lower Silesia ; and in 1868 Lord Walsingham introduced some into his Merton estate. According to Siebold (1863) the fine black spotted, or orange-yellow or red variety is indigenous in Upper Silesia. Although this variety renders it a valuable addition to aquaria and pieces of ornamental water, its colours, on the other hand, cause it to be readily perceived by its enemies, including poachers. Names. Sliw, pronounced " slew," Anglo-Saxon. Gwrachen and Ysgretten, Welsh. Be ZeeU, Dutch. Tanche, French. Habits. The tench prefers still waters to running streams, more especially thriving in reservoirs, ponds full of water-weeds, and pits from which clay has been excavated for brick-making. It seems, also, to do better in foul and weedy than in clean water, and in broads and sluggish rivers as the Thames than in those which flow with considerable velocity ; while muddy and marly bottoms are especially suitable to its prosperity. Where carp are found such localities are commonly well-adapted for tench. It is generally seen in small companies, and appears to frequently keep near the bottom, except during the summer, when, more especially during spawning time, it lies near the surface among the weeds. Although possessing a very thick skin and covered with a large amount of slimy mucus, it seems to be very susceptible to cold, and has been credited with passing a considerable portion of the winter months in a semi-lethargic condition buried in semi-aquatic mud. It will dive down into the mud in order to escape from nets, while its " run " differs from that of the rudd or bream, being short and irregular. It is very tenacious of life, in which respect it is but little inferior to the eel among fresh-water fishes. Pennell states that he has known one to live for an entire day with the gimp of a double jack-hook passed under its skin from its gills to its tail, the fish being meanwhile cast about from place to place in the water and suspended in a most unusual position. Tench have frequently been observed to live a whole day out of water. It feeds on insects, larvas, worms and vegetable substances, and a correspondent of the Field (November 5th, 1881) remarks that he took " a tench of 4 lb. while perch fishing with a small red worm. This may or may not alter the theory that they do not feed during the winter months ; but this season, in the Lea, a goodly number have been bagged when least expected.^ It is curious to observe the contorted positions in which these fish apparently go to sleep ; sometimes the head rests on the floor of the aquarium, some are bent into most uncomfortable-looking shapes, while they lie so motionless as to appear to the observer as if they were dead. 190 PHYSOSTOMI. Daniel mentions the capture of a tench 33 inches long to the fork of the tail, and which weighed 11 lb. 9 oz., its belly being of a vermilion colour ; it was taken under some roots at the side of a pond, in which contracted situation it had literally assumed the shape of the hole in which it had, of course, for many years been confined. It has been computed that these fish can live in water in which the amount of oxygen has been reduced to the 5000th part of the bulk of the water, ordinary river water containing about 1 part in 100. In some pits they breed but and never attain to any size ; in other ponds they grow, but never breed. Means of capture. It is rather readily captured, and esteemed a foolish fish by many fishermen ; it takes a bait throughout the spring and summer. In Norfolk, according to Lubbock, formerly the fishermen on the broads relied upon the bow- net, and occasionally the trammel or flew; but of late years, and in shallow waters, they prefer their own hands, with a landing net to be occasionally used. A small low-sided steady boat is employed and poled along, the fisherman lying down with only his head over the gunwale and his right arm bared to the shoulder, he gently displaces the weeds and tries to descry a tench. If he sees one, and how its head lies, the chances of success are increased ; if not he slowly and cautiously touches it, which is only taken notice of should the tail be touched, when it dashes away. The fisherman tries to insinuate one hand just behind the gills, raising the fish gently but rapidly to the surface, but must not knock the boat or the jar wakes up the tench, which at once struggles. Baits. Paste, worms, gentles. In old works tar was recommended to be added to the baits used for this fish as it was said to be very partial to it. Breeding. Occasionally at the end of May ; more commonly in June, or at the beginning of July. The female tench is generally accompanied by two males. The eggs are small and deposited in the weeds. M. Petit found nearly 350,000 in one specimen. Harmer examined seven and found from 83,104 to 383,252 ova, or an average of 211,826 in each. Bloch, from a 4 lb. specimen, obtained 297,000. It does not breed so rapidly in rivers as in ponds and broads. In the male the outer ventral ray and, in some instances, several more are enlarged and thickened, while at the breeding season the basis of the ventral fin are inflamed and often excoriated. In stocking breeding ponds two males ought to be employed to each female. In places it is found to be rather a rapid grower, this being especially affected by the temperature of the water and the amount of food ; it has been known to attain from i lb. to 1 lb. in twelve months, and an instance has been recorded where one in a pond in six years was 4|- lb. weight. Diseases, etc. Much affected by thunderstorms : the effects on fish contained in trunks appears to be partial. All the fish in one trunk on a particular broad perish during a thunderstorm, while not one of those contained in another trunk in the same water is injured (Lubbock). Uses. It has been termed the " Fishes' Physician," and Camden in his Britannia observes that he had seen the bellies of pikes which have been rent open, have their gaping wounds presently closed by the touch of the tench, and by their glutinous slime perfectly healed up. (See also page 143.) A knowledge of this among fish has been said by many ichthyological authors to induce, pike, perch, and eels to spare the tench. Salter asserts, that having laid trimmers baited with live roach, dace, bleak, and tench, the eels and pike refused this latter fish as a bait, and that he only met with one instance to the contrary. Two reasons have been given why pike do not destroy them, one is that they live in the mud where they cannot obtain them : the second, that they purposely abstain from devouring them. Mr. Barr, on the contrary, asserts that you cannot put a better bait on a trimmer than a young tench, while out of the stomach of a trout he took twenty-two of the size of minnows. Mr. Slaney (Zool. 1853, p. 4021) observed a pike which had seized a tench of about 3 lb. weight cross- wise but was unable to swallow it, and at last the tench got away. " This is the only instance I ever met with in which the tench was attacked by any other fish, though I have constantly had them put together with pike and perch in small streams and other places, where the absence of food for the predatory species CYPRINID^E. 191 lias induced tliern to seize upon almost every other living thing ; all other kind of fish, rats, young ducks, and moor-hens have fallen a sacrifice to the all-devouring pike, but not the tench ; and keepers always avoid setting their trimmers or trolling for pike with a tench for a bait, alleging as a reason that no other fish will touch it." A few days subsequently he found the above fallacious, as he saw another tench undergoing the same process, and afterwards found a dead one which evidently had been injured by a pike, and on dragging the pond only three or four were caught out of ten or twelve brace that had been put in, the rest appeared to have been destroyed by the pike (Zool. p. 4100). A tench of 71b. weight was taken at Frogmore Gardens, Windsor, from the pouch of a pike between 30 lb. and 401b. weight (G. Gujon, Zool. 1867, p. 563). Mr. Gurney (Zool. 1853, xi, p. 4124) observes that he has seen a tench taken out of the stomach of a pike. " In the autumn of 1848 I turned into a pit, which I believed to contain no fish of any kind, fifty small tench, and forty or more crucian carp ; seven tench and twenty-four crucians were also turned in at a subsequent period. October 13th, dragged the pit and took three lanky pike, 3 lb. 2 lb., and H lb. weight. All that remained of the stock were one tench 1| lb. weight and eight crucians of about 1 lb. each." In olden times it used to be applied to the palms of the hands and feet in order to absorb fever : or laid over the liver in cases of jaundice, when the fish, it was asserted, became yellow and retained the disease. A live one tied to the temple has been stated to remove a nervous headache, or worn round the neck to cure sore eyes. It has also been recommended in obstinate cases of worms ! As food. It has been variously esteemed, being rejected by some as unpalatable or even unwholesome, whereas others have considered it to be among the best of our eatable freshwater fishes. Most of our abbeys and monastic establishments maintained stews where these fish were kept, which would seem to show they considered them to be delicacies. The taste of course considerably depends on the waters it has inhabited and the food on which it has lived. It may be placed in a stew and fattened with a mixture of greaves and meal. Respecting the effect of the character of the water in which it lives upon its suitability for the table, we are infor-med that no tench could be better grown or of sweeter flavour than some taken out of Munden Hall, Fleet, Essex, which was so thick with weeds that the flue-nets could hardly be sent through them, and the mud was so intolerably fetid that it had dyed the fish of its own hue, which was that of ink. This, however, differs from the experience of many who generally find that a pond tench is muddy and not always desirable for the table if other fish are procurable. A quantity of tench averaging about 3 lb. each, and of a golden colour, were taken from a clear pond at Leigh's Priory, but when dressed and brought to table smelt and tasted so rank that no one would eat them. This has been given as an instance, showing that clear water will not always render these fish eatable. At the Fisheries Exhibition some tench were placed in one of the cemented tanks and some earth and sods placed for them to grovel amongst. After about six weeks a brace were cooked and better fish could not have been desired. Some of the gold variety were also similarly treated, but they were somewhat inferior. A good tench is certainly by no means despicable as food, while its best season is from the commencement of September to the end of May. Habitat. Extended throughout the fresh waters of Europe into those of Asia Minor. Malmgren. I.e. fixes 62 N. Lat. as the northern limits of this fish in Finland. In Scotland. A beautiful specimen was captured in the Moray Firth in the middle of June, 1863, from whence it came and how it fared is a mystery (Edward) ; it thrives in Aberdeenshire and a few are found near Edinburgh. One upwards of 2 lb. was taken at Kelvedon (Denny, Hard. Sc. G. 1867, p. 17). Present in Hirsel Lough, an artificial piece of water in Berwickshire, first filled in the month of December, 1876. It is not so common in the western as in the eastern counties of England. It was introduced into numerous ponds, reservoirs, canals, and some sluggish streams in Yorkshire (Yorkshire Vertebrata). In Norfolk from 14 to 192 PHYSOSTOMI. 17 inches in length is considered that of a good table fish, while a 4 lb. fish is a large one. Mr. Gurney says, " The only river locality I know for the tench in Norfolk is the Tare above Trowse." It occnrs also in the Ouse above Denver. Mr. Norman took one near Yarmouth weighing 5 lb. 14 oz. (Lowe). It is by no means rare in the Thames, and found in many of the midland counties as well as in some parts of Wales. It is also present in our southern counties, and large ones are occasionally captured in Hampshire, while it exists in the Isle of Wight (Moore). In the Exeter Canal and some of the ponds of the South Devon Railway (Parhtt). Found in the ponds at Trengwainton, where they were placed by the late Sir Rose Price, Bart. (R. Couch). It is a common pond fish in Cornwall (Cornish). In Ireland. Templeton considered that it has been introduced, it is noted in County Down, counties of Dublin, Cork, Westmeath, and in Lough Derg, near Portumna. Templeton observed " Many were caught in the river Lagan after the breaking of the bank of a pond in the demesne of Lord Dungannon at Belvoir." A correspondent of the Field (June 16, 1883) writing from Lough Derg, says tench were first heard of here three years ago, since then he has obtained a few all about 5 lb. weight. Pennant observed having heard of one 10 lb. while Salvianus speaks of a 20 lb. tench. CYPRINIDvE. 193 Genus VII Abeamis, Cuvier. Blicca, Bliccopsis, Ballerus, and Alburnus, sp. Heckel.

Eyes diameter 4 to 5-| in the length of the head, H diameters from the end of the snout, and 2 diameters apart. Body oval, elevated and strongly compressed. Head small, snout short and obtuse, mouth protractile and small, upper jaw slightly the longer and reaching posteriorly to below the anterior nostril: lips moderately developed. Teeth pharyngeal 5/5 compressed and notched at their extremity. Fins the dorsal commences slightly behind the base of the ventral and about midway between the front edge of the eye and the base of the caudal fin, and just below the end of the highest point of the dorsal profile, while its last ray is on a line with the first of the anal: it is highest anteriorly. Pectoral inserted low down and as long as the head excluding the snout, it reaches to above the commencement of the ventral and the latter to the origin of the anal. The anal fin is falciform, and highest anteriorly. Caudal deeply forked. Scales of medium size, higher than wide, Q\ or 7-i between the lateral-line and base of ventral fin. On the edge of the abdomen between the ventral and anal fins, the scales do not pass across forming a sharp keeled edge. Lateral-line curves downwards, passing along the lower third of the body to the base of the caudal fin. Colours back of a dull olive or sea-green, lighter on the sides and beneath, the abdomen being silvery tinged with pink. In old fish the body becomes more of a yellowish colour. Fins brownish, the pectoral rays being often tinged with scarlet, which colour may be seen in the first few rays of all the other fins. Varieties. This fish is subject to considerable local variations of race, so much so that without a series of specimens it might almost be thought that new species were being obtained. Names. Common bream, yellow bream when old due to its colour : carp bream., when its colour resembles that of a carp. Brem, Welsh. Be Brasem, Dutch. La Breme, French. Habits. This gregarious fish, which is of a hardy nature, is found in many sluggish rivers, canals, ponds, broads, and lakes in this country, but swift running waters and pebbly bottoms are unsuited to it. Donovan observes that the fisher- men assert that when the bream ascends rivers they are collected into small shoals, each of which is preceded by a leader who directs the course of the shoal and differs in appearance from the rest. This is called by the fishermen the " Queen bream." This, however, is thought by some to refer to the hybrids which will be presently described. It feeds on the larvae and adult of water insects, on worms, as also on aquatic vegetable siibstances, and is very tenacious of life. CYPRINID^E. 195 In Norfolk we are told that should a bow-net be set for tench, bream crowd in before they arrive and thns exclude them. In perch- fishing it consumes the anglers' best worms, tries his patience, and soils his fingers. One of the great evils of this fish is its excessive increase, which occasions it to consume all the food which might have been available for better forms of fish. In Sweden it is considered a timid fish, and Nilsson observes that during the period its fishing is carried on, it is forbidden to ring the church bells lest they might be scared. The shoals of these fishes are said always to have a sentinel on the watch. Means of capture. Bottom fishing, one of the best baits being small red worms and brandlings. When hooked in deep water it bores down into the mud,, rubbing the line with its tail, thus causing it to be muddy for some distance above the hook, while it is a very suspicious fish, and considerable caution is necessary in order to avoid letting one's presence be detected. From July to October are perhaps the best angling months for the bream ; the warmer the day the better, while it bites best of a morning and evening. Thompson remarks that it is taken with the greatest success in the Lagan by ground baiting with balls of grain from the distilleries, seeds (cast off from flummery), or boiled oats, being mixed up with potatoes in the form of balls, and thrown into the river at night. Bream collect from all quarters to partake of it, and the next day anglers employ worms as bait, generally with success. In Ireland it is netted in large numbers. Baits. Worms. Dr. Norman, of Yarmouth, says they must be worms of the largest size, not those dug out of the ground. They must be picked up off the grass at night. A good ground bait is half a pailful of bullock's blood, a pailful of fresh grains, half a pailful of very clean clay, a handful of dogs' greaves well broken up, three handfuls of meal, and a little oilcake. This is worked into a pudding and divided into balls not quite so large as a child's head, and partially baked in the sun. In June and July it will take a grasshopper from which the legs have been removed. Small hooks and light but strong tackle are necessary, and the angler that strikes at once on receiving a bite will have most chance of success. Breeding. When preparing to spawn about May, Lubbock observes, " they roll about like miniature porpoises, and the water is discoloured by their work- ings. Here a nose appears, and there a back fin, while at intervals a plunge of affright amongst the multitude shows that a large pike is busy." In Norfolk it generally selects a broad as a breeding-place, while the eggs are of a reddish colour, and Bloch observed 130,000 in one fish. One female is frequently attended by as many as three or four males. During the breeding season the scales feel rough to the touch, due to small whitish tubercles which appear upon them at this period. Hybrids. I have already remarked (p. 177) how hybrids between the roach, Leuciscus rutilus, and other Cyprinidas cannot occur in Ireland because the roach of that country is L. erythrophthalmus, or the rudd, which is termed a roach in the Emerald Isle. It is not, however, improbable, that elsewhere the L. rutilus may also assist in the creation of hybrids with the bream. The following, which has been found in Ireland, may be deemed a cross between the bream and the rudd. B. iii, D. 13-14 (), P. 15-17, V. 9-10, A. 17-22 (^ 3 T ), C. 19, L. 1. 45-52, L. tr. 8 f_y, Vert. 41. Pharyngeal teeth usually in one row, but in rare exceptions a second row, formed by means of a single additional tooth. Thompson observes that in Ireland this form has been captured in the river Lagan, where the common bream is abundant. It has also been taken at Cossey, above Norwich (Lubbock), Dagenham Breach in Essex (Yarrell), Cambridgeshire (Jenyns), Wolverhampton (Edwardes), and some other districts in England, Holland, and Germany. Uses. Food for pike and ohter rapaciouB fishes. Mr. Gurney observes that once, when trolling for a pike in a pond where bream was found, the keeper 13 * 190 PHYSOSTOMI. insisted that they never took the latter ; so to test this he employed a small bream for a bait, Avitk which he took a pike. Numbers are employed in Norfolk as bait for crab and lobster pots, for which they fetch 2s 6d a bushel, while there is likewise a considerable demand for them as food in the Midland counties. As food. Employed for this purpose to a considerable extent on the Continent, but, due to its numerous bones and the softness and insipidity of its taste, it is not much thought of in this country, and one authority likens it in shape to a pair of bellows, and with much the same flavour. However, opinions have and will differ on this point, and its best season for the table is during the spring and autumn. Walton observes that in the autumn they become as fat as a hog, when they afford a not unpleasant dish. In the Book of St. Alban's " the breeme " was considered " a noble fysshe and deynteous." Chaucer spoke well of it as food, and Dugdale informs us that about 1410, when the daily hire of a mason or carpenter was less than sixpence, that a single bream was valued at twenty pence. Also that a bream pie contain- ing four of these fish was sent from Warwickshire to a distant part of Yorkshire at the cost of sixteen shillings, which included the wages of two fishermen for three days in catching the fish, together with the cost of the flour and spices for making the pie, and also its carriage. Habitat. The middle districts of Europe, and northwards to St. Petersburgh, Finland, and Scandinavia. Here it is local in its distribution, being found in the lakes of Cumberland. In Yorkshire it is only recorded from the lower reaches of the Don, Wharfe, Ure, Colbeck, Derwent, and Hull, as well as in canals. The commonest fish of the lake Somerwater (Yorkshire Vertebrata). In Norfolk found in immense shoals in all the broads. It is found in the Trent, the Ouse, the Thames, the Wey, the Lea, the Mole, the Medway, and in the Pulborough and Amberley waters. Also in our central counties, but is absent from Devon- shire and Cornwall. In Wales, Swansea (Dillwyn) ; it has also been recorded from Brecknock and other places. In Ireland it is found in many of the lakes and slow running rivers, as Cavan and Fermanagh in the north, while in Lough Erne it attains a large size. In 1835 Thompson observed that there were numerous bream in the Lagan ; but an old fisherman assured him that twenty years previously there had been none. At Cossey, in Norfolk, it has been twice captured at 7 lb. weight, and Mr. Norman, of Yarmouth, took one, a female, of 8 lb. 12 oz. (Lowe). One, a male, was taken near Cromer on June 17th, 1879, which weighed 11^ lb., and must have been at least 26 years old ; it was 26 in. long and 10 in. deep. Jenyns observes their weight sometimes exceeds 12 lb., and on the Continent to 14 lb. Thompson alludes to Irish specimens of 7 lb., and Yarrell to 12 lb., or even 14 lb. Baily (Anglers' Instructor) mentions one of 17 lb. in the Trent. b. Pharyngeal teeth in two rows Blicca. 2.

Colours silvery, darkest along the back, sides tinged with rose red, fins of a bluish colour, the dorsal anal and caudal with dark outer margins, the pectoral and ventrals tinged with red. Varieties. The Rev. R. Sheppard (Linn. Trans, xiv, p. 587) observed that there exists in the river Trent in the neighbourhood of Newark, two species or varieties of bream. The common one is known by the name of the "carp-bream" from its yellow colour, and has been taken of nearly 8 pounds weight. The other species or variety, which I believe to be a nondescript, never exceeds a pound in weight. It is of a silvery hue and goes by the name of the " white bream." Names. Taylor, in the Thames valley on the border of Bucks and Berks. Breamflat, Cambridgeshire. Shude, Ireland. YMerfog aughrion, Welsh. Bremettis, Book of St. Albans. Be Blei, Dutch. La Breme Bordeliere, French. Habits. Does not appear to collect in large shoal?, and is more commonly found with the rudd and roach than the true bream. It is lively, sportive, and tenacious of life. Lubbock observes that its mode of biting when angled for is singular, as it appears more prone to rise than to descend, and the float conse- quently, instead of being drawn under water, is laid horizontally on the surface. Means of capture. Takes a bait readily but said to be too indolent to swallow it, still the Swedish fishermen term it Aetare or glutton. As food. Worthless. Breeding. Bloch found 108,000 eggs in one fish. A hybrid between this fish and the rudd (see p. 176) has been observed in Holland and Germany. Habitat. In Europe the same as the common bream. It has been obtained from Loch Maben in Dumfriesshire ; from the Trent near Newark ; the Cam, where it was termed the " breamflat " ( Jenyns) ; and from the Norfolk boards. It rarely exceeds a pound in weight. 198 PHYSOSTOMI. Genua VIII Alburn us, Heckel. Body rather elongated and compressed. Upper jaw protractile.

Bleak also spelt blick, bleik or bleis, a term derived by some from the old Saxon word "blac" which signifies "white," or according to Merrett from the northern word "blick," which means to "bleach" or whiten. From this word " bleak" have sprung local terms as blaze, blay, willow blade. Ablet, Westmorland. While Izaak Walton called it the "freshwater sprat." Gorwynbysg, Welsh. Het Alvertje, Dutch. L'Ablette commune, French. Habits. Is very common in many rivers, living in shoals, revels at outlets of drains and is somewhat of a surface swimmer. Ever in motion, never at rest, darting about at the surface of the water, especially during sunny weather, so as to have obtained the name of the " river swallow," and springing out at flies, or infesting rivers in shoals, near the openings of drains. Siebold asserts that it occasionally springs out of the water to escape some rapacious fish as perch which is about attacking it from beneath, and thus eludes its enemy. The bleak is infested with parasitic worms which some authors consider to be frequently the cause of its eccentric gyrations in the water, and have gained it the epithet of "mad bleak." It has, however, been remarked that they are only in this wild condition during certain states of the water. Buckland observes that at the Severn at Shrewsbury he went to the mouth of a sewer : the water was ink black from waste dye, and so warm that steam was on the surface ; bleak were here in vast shoals. In June, 1881, it was remarked in the Field, that the dace which used to afford so much sport to anglers when the river was in a natural state, are not now to be found except in a very limited degree, and the migrating fish as bleak, twaite shad, lamperns and lampreys are becoming scarce. This year, however, the little bleak has shown itself in large shoals ascending to considerably above Shrewsbury. Means of capture. Netting, or it will l'ise to the fly. Baits. A common fly, a bit of fat bacon, or a small artificial gnat, a gentle at the end of a casting line, or a bit of kid on the end of the hook. Breeding. May, June, and even July, during which period its head and gill-covers are rough to the touch. In Sweden Nilsson remarks that the largest and oldest are the earliest to breed. The young grow very rapidly. Hybrids. Jackel describes from Bavaria a reputed hybrid between Alburnus lucidus, and probably Scardinius erythro^Mlialmus, which he terms Alburnus Bosenhaueri (Zool. Garten, 1866, p. 20). Uses. A good spinning bait due to its silvery whiteness, but it dies too soon to succeed as live bait. The silvery pigment with which its scales are lined has been extensively used in the manufacture of artificial pearls. One thousand bleak are computed to yield 1 lb. of scales, and this four ounces of precipitated white powdery pigment. Yarrell remarks in his time first the slime and dirt was carried off from the scales by a run of waier, they were then soaked for a time when the pigment was found at the bottou^ of the vessel. Into this glass tubes were dipped and the pigment injected into thin hollow glass beads of various forms and sizes. These were then spread on sieves and dried in a current of air. If greater weight were required an injection of wax was added. Pigment from the 200 PHYSOSTOMI. scales of the roach and dace was said to be the best, but that from the bleak in greater request. So great was the demand formerly at particular times that the price of a quart measure of fish scales has varied from one guinea to five. Of late years the silvery pigment lining the air-bladder of the Argentine has superseded to a great extent the colouring substance from fish-scales. Blanchard gives as an estimate of the value of these fishes taken in the Moselle in 1860 at 5000 francs. As food. Izaak Walton terms it excellent meat, others liken it to sprats ; while it has been recommended marinated. Some who have failed to appreciate the bleak, assume that it is neither worth cooking nor eating, that its taste is muddy, while it is too large to employ as whitebait, and too small to afford a good mouthful. It dies quickly, and its flesh soon decomposes. Habitat. Generally found in rivers which contain roach and dace, and in Europe north of the Alps. Absent from Scotland and Ireland. Is a freshwater resident in Yorkshire, common in the lower waters of the Tees, Leven, and of the Central Plain ; also in the Hull (Yorkshire Vertebrata) ; very abundant in ditches at North Wootton, in Norfolk, the Ouse, below Denver sluice, at low water (Lowe) ; the Thames, certainly as high as Oxford, the Lea, and New River, the Severn, and many of our rivers. Its common size is up to 5 or 6 inches. Jenyns mentions specimens up to 8 inches. The figure, life size, is from one taken in the Thames. cyprinlcle. 201 Second Group Cobitidinae. The loaches, or the second group of the true carps, is comprised of forms in which the two lateral portions of the air-bladder are partially or entirely enclosed in bone, enabling it to be employed as an acoustic organ. These are mostly small fishes, and the two genera represented in Great Britain may thus be recognized : With an erectile spine near the orbit . . . Gohitis. Without any ...... Nemacheilus. Genus IX Cobitis, sp. Artedi. Botia, sp. Gray. Body elongated and moderately compressed : bach not elevated. Six barbels, all of which belong to the upper jaw. A large erectile, bifid, suborbital spiyie. Dorsal fin short, and commencing nearly or quite opposite the ventrals. Caudal fin truncated or rounded. The internal ray of the pectoral fin may be modified into a flat osseous spine. 1. Cobitis taenia, Plate CXXXVII, fig. 3.

Eyes 5 to 6 diameters in the length of the head, and situated about its centre, from 1^ to 2 diameters from the end of the snout, and 1 diameter apart. Body strongly compressed, more especially posterior to the dorsal fin. Mouth 202 PHYSOSTOMI. overhung by the snout, both its cleft and gape small, the posterior extremity of the maxilla reaching to beneath the hind nostril. A strong bifurcated suborbital spine situated beneath the hind nostril, and extends to beneath the first third of the orbit. Barbels short, six in number, all inserted on snout and upper jaw. Teeth pharyngeal, in a single row, 8-10/10-8. Fins the dorsal commences above the origin of the ventral and about midway between the end of the snout and the base of the caudal fin. Pectoral almost as long as the head in the males : the upper pectoral ray is osseous, enlarged and flattened.* Caudal cut square or slightly emarginate. Scales very minute. Lateral-line present, passing along nearly the middle of the side. Colours of a light brown, becoming white along the abdomen : two rows of dark spots along the back and upper half of the sides, and a third of larger marks below the lateral-line : these marks are sometimes converted into transverse bands : a black streak from the eye to the snout : a black blotch on the upper portion of the base of the caudal fin. Pectoral, dorsal and caudal fins banded with dark marks. Names. Spined loach, denoting its preorbital spine ; ribbon-shaped loach, having reference to its shape. Be Kleine mo dderhr wider, Dutch. La Loche de Riviere, French. Habits. But little is known of the habits of this species of loach in this country, where not only is it local but rare. It appears to be more of a mud- loving form than our groundling, while it is tenacious of life. When touched it is said to emit a peculiar guttural sound. Breeding. March and April in France, and very prolific. As food. Said to be inferior to the common loach, but still it is much esteemed. Habitat. Distributed through most of the continent of Europe. In Finland it is rare and local, but generally found through Denmark and the northern half of Sweden. It is a much rarer form in Britain than the common groundling, Nemacheilus barbatula. Parnell observes that he thought he saw one in the River Teith in Scotland, but he failed to obtain it. It has been recorded from the Trent near Nottingham : from fish ponds at Ely and in other pieces of water in Cambridge- shire (Jenyns) : clear streams in Wiltshire, and Thompson obtained it from near Guy's Cliff in Warwickshire in July, 1836 : Couch also observes that he believes it is found in Gloucestershire. Newman (Zool. 1855, xiii, p. 4836) remarked that he took this species at Dorking in a little muddy stream that runs into the Mole, just below the bridge at Brockhara Lodge. But although he describes it he omits any reference to the spine below the eye (? next species). It has not been recorded from Ireland. Rarely exceeds three inches in length. * Cedcrstrom, JEiv. Ak Forh. xxxi, 1874, p. 47, pi. xi, f. 5-8, observes on the habits of this fish, and how the sexes are differentiated by external characters. CYPRINID^E. 203 Genus X Nemacheilus, Van Hasselt.

Length of head 5 to 5|, of caudal fin 6 to 6|, height of body 6 to 8 in the total length. Eye 5 to 6^ diameters in the length of the head and situated about its centre, from 2 to 3 diameters from the end of the snout, and li to 2 apart. Body rounded anteriorly, but compressed in its posterior half. Mouth over- hung by the snout, which is obtuse : cleft shallow : the posterior extremity of the maxilla reaches to beneath the hind nostril. No spine on the head. Barbels six, all inserted into the snout and upper jaw. Teeth pharyngeal ; in one row 8-10/10-8, pointed and crooked at their extremities. Fins the dorsal commences above the insertion of the ventral and rather nearer the base of the caudal fin than the end of the snout, or midway between the two. Pectoral as long as the head excluding the snout. Caudal cut almost square at its posterior extremity, with its corners rounded. Scales minute, and mostly concealed in the large amount of slime with which the fish is covered. Lateral-line distinct along the middle of the side of the body. Colours these are subject to great variation, mostly of an 204 PHYSOSTOMI. olive-green blotched all over with dark markings : abdomen white. Fins blotched and banded with darker. Occasionally it is more yellow, with ill-defined spots and blotches. Generally a black mark at the base of the caudal fin above and below, but most distinct above. Varieties. Siebold observed one from Munich of a reddish colour, and having a red pupil : Baldner, of a pale-coloured loach. Names. Groundling, from its remaining at the bottom of streams or waters : stone-loach, due to its fondness for secreting itself beneath a stone : ground-bait, or ground gudgeon, Northumberland : lie-still, South Hampshire : also locally as beardie, tommy loach, or tommy lurher. La Loch Franche, French. Habits. Clear rivulets with gravelly bottoms, which it prefers to broad rivers, and keeps near the ground, rapidly darting away if disturbed ; it is also found in pools. Appears to be very susceptible to atmospheric changes ; thus, when kept in an aquarium, Couch found that it would throw itself over the walls of its prison, especially at the approach of, or during any remarkable changes of wind or weather. It similarly commits suicide by springing out of ponds or streams. Newman (Zool. 1855) says that in an aquarium it remains motionless at the bottom for the greater part of the day ; but towards evening, and in showery weather, it presently comes to the surface, with a wriggling movement of its eel-like body then drops languidly to the bottom. The loach has been kept alive in aquaria as a living barometer from the supposition that certain movements and alterations of position or situation indicate particular changes which are about to occur in the weather. It is very voracious, and will feed on larva? and adult insects, as well as consume an incredible number of small worms, i.e., from 1| to 2 inches long. As soon as one is seized it stirs up the mud, and so becomes invisible. In a state of nature it lurks in long floating grass quite as commonly as under stones, and when rivers are flooded and very muddy, it often seeks refuge at the sides, under banks, and among small tufts of grass. Means of capture. A fine hook and line : baling out streams, or netting. Boys spear it with an ordinary fork tied on the end of a stick. Baits. A small worm. Breeding. Spawns in March and April : depositing numerous small ova. It has always been considered one of the most prolific of our freshwater fishes. Uses. Very good spinning bait for trout, perch, and small pike. Large pike high up streams will sometimes take them after refusing roach and dace. It is said to be rendered more killing if steeped in sweet oil, which changes its colour into a golden tint. A good bait on night lines for eels, while chub will also take it. Owls have been observed to feed their young with this fish. As food. Excellent flavour and very delicate. B-utty remarks that " it is customary with many to take it alive in a glass of generous wine " (i, p. 866) ; but Pennant observes that sportsmen do so through frolic. Izaak Walton con- sidered it a dainty dish at table, and Gesner terms it the "invalid fish," the best being fed and bred in little clear and swift brooks or rills over gravel. Frederick the First of Sweden went to the expense of having this fish imported into his country from Germany for his own particular eating. It is occasionally preserved as anchovies, and considered superior both in flavour and richness. Habitat. Absent from Scandinavia and Denmark, but distributed over most of Europe. In many of the streams of the north of Scotland, and in all the rivers entering the Firth of Forth (Parnell), the Tweed, and the burns of Berwickshire (Johnston) ; in the waters of Leith (Neill). In Yorkshire abundant in shallow waters. Found in the North-Western Fells up to 900 feet ; also in Malham Tarn, 1250 feet (Yorkshire Vert.). In Norfolk found in the smaller streams, wherever stones afford a lurking place" (Lubbock) ; and it has been specially mentioned in many other localities to so far as Cornwall : also in Wales. In Ireland taken in counties of Londonderry, Monaghan and Cavan ; Florence Court : counties of Dublin, Kildare, Cork and Wicklow. I found it abundant at Edgeworthstown, county of Longford. It rarely exceeds 5 inches in length. CLUPEIDvE. 205 Family, V CLUPEIDtE, Cuvier. Gill-openings usually very wide; pseudobranchiae, when present, well developed. Abdomen mostly compressed, generally into a sharp edge, and usually serrated. Opercular pieces, four. Eyes lateral, with or without an adipose covering or lateral lids. Margins of the upper jaw formed mesially by the premaxillaries, laterally by the maxillaries, which latter are composed of three pieces not ossified together. Mouth may have a deep cleft, with small premaxillaries and the maxilla elongated, and either the upper or lower jaw projecting; or the mouth may be transverse. Barbels absent. Fin rays articu- lated. A single dorsal, with a few or moderate number of weak rays, and sometimes many rayed. Scales on the body : none, as a rule, on the head. Lateral-line mostly absent. Stomach with a " cul de sac." Air-bladder more or less simple. Pyloric appendages, when present, numerous. Although, in our seas the herrings are merely represented by six species, still one, or the true herring, is among the most valuable of our marine fishes ; another, the pilchard, is likewise of considerable importance ; and a third, or the sprat, is of great economic use. An account of each of these fisheries will have to be detailed, consequently it is merely necessary in this place to draw attention to some phenomena which are common to the members of the entire family. Most of the fishes of which the family of herrings is composed are gregarious forms that congregate in shoals, and, as a rnle, swim more or less near the surface. They have no means of defence against predaceous foes, and are preyed upon by numerous enemies, to counterbalance which they are endowed with great prolific powers. It appears somewhat improbable that man, with his present implements of capture, will be able to annihilate the herring shoals in our seas, but without doing this he can scare them, and so break up the shoals by injudicious modes of fishing. He can likewise drive them from certain shores into the deeper water, where they may form a deep-sea race ; or he may occasion their entirely forsaking a locality. Geographical distribution. Herrings are found in most seas, and many enter fresh waters. Synopsis of Genera. 1. Engraulis, or anchovy. Upper jaw prominent, mouth with a very deep cleft, eyes covered by skin. 2.

De Ansjovis, Dutch. It Anchois vulgaire, French. Habits. A gregarious marine fish which hangs about our south coast from September until February, in dark nights appears to give a phosphorescent light to the sea : while Dillwyn observes that off Swansea in some summers there are vast CLUPEIM]. 207 numbers in the Bay. Couch obtained one in Cornwall in March, from the stomach of a mackerel. It approaches our shores somewhat later than the pilchard (was plentiful in October, 1883), and continues off the coast generally till February. Mr. Wilcocks (Field, Jan. 13th, 1883) only met with them twice in his life along the south-west coast of England, once at Exmouth, the other time at Teignmouth, and found them both poor in taste as well as bitter. They are only taken by chance in drift nets or seines for sand-eels, as their small size enables them to pass through the meshes of such nets as are generally used by the drift net fishermen. In November, 1871, Mr. Dunn reported that upwards of 150,000 were taken in the seines set in Mevagissey Bay for pilchards, and were used as manure. It is seldom, however, they come so close in shore, although quantities hang in the offing off the coast from September until February. Said to eat small crabs, fry and sea insects. Means of capture. In the Mediterranean from May until July, dark nights are selected, and each boat carries a torch to attract the fish, when the shoals are surrounded by small meshed nets, while the fishermen splash the water in order to draw the fish which dart about and become gilled. Breeding. In the Mediterranean from May until July (Bloch) and very prolific : off our coasts from September until December. Mr. Jackson remarked that on June 9th, 1878, off Southport, he took some dozens in a shrimp trawl on a sandy bottom, about half a mile off shore. Unfortunately nearly all the scales came off in the net. Many were full of spawn and so tender that they burst with the slightest strain. Uses. Anchovies are prepared by drawing off the head and removing the viscera, they are not washed or wiped, but packed into small casks of 5 lb. to 201b. weight, in layers alternately with a mixture of Jij sal prunella (saltpetre deprived of water of crystallization by heat), and should be well pressed down and air excluded. Anchovy sauce is made by bruising fish and simmering with melted butter on a slow fire, a little vinegar and flour being added. The fish dissolves in the process. It is one of the fishes from which the Greeks and Romans prepared the sauce, garum, which was held in so much estimation. As food. It is rarely eaten fresh ; in fact, it is strongly scented and so bitter that it has been said to carry its gall in its head. But prepared anchovies and anchovy paste are much relished. Habitat. Taken in innumerable quantities in the Mediterranean and extending northwards off Norway and the Baltic. It is found on both coasts of France, but most numerous on the Mediterranean side, also along the Iberian peninsula from Gibraltar, and from thence eastwards to Greece and the Black Sea, while a variety has been found in Tasmania. This fish was first obtained on our coasts by Ray from the estuary of the Dee. Mr. Peach has taken it from the herring nets off Wick, while there is one in the Newcastle Museum, taken in 1834 from some sprats being sold in the market, Durham (Jenyns). It appears to extend its range around our coasts, especially in the south and south-west, and has been specially referred to as present in Yorkshire (Yorkshire Vertebrata) ; three taken at Bridlington Bay, October 17th, 1866 ; rare at Yarmouth (Turner) ; frequently taken in the stow nets during the summer months in the river opposite Lynn (Lowe) ; Boston, Lincolnshire (Adcock), coasts of Essex ; and Yarrell received an example from the mouth of the Thames, where, however, it was not known by the fishermen; Hampshire (Donovan). Often captured in drift nets in the west portion of the British Channel. Sometimes taken in the Exe (Parfitt) : quite a common fish in the autumn from Polperro to Falmouth (Dunn) ; while the same authority reported the capture of at least 150,000 in November^ 1871, at Meva- gissey, where they were employed as manure : occasionally taken in St. Ives' Bay (Cornish). In Wales it has been recorded off Glamorganshire: Swansea, where it is abundant in some seasons: Flintshire (Pennant). In Ireland Andrews reported it found off the coast. The anchovy is common up to 4| or 5 inches in length, rarely exceeds 6|; but Mr. Dunn has obtained it from pilchard nets off the Cornish coast 8 inches long. 208 PHYSOSTOMI. " Genus II Clupea, sp.

Body oblong or somewhat elongated, with the serrature of the abdomen extending anteriorly into the thoracic region : upper jaw projecting beyond the lower. Mouth anterior or antero-superior. Eyes with free adipose lids. Teeth, when present, rudimentary and deciduous. Dorsal fin situated opposite to the ventrals ; anal with a moderate or large number of rays : caudal forked. Scales large, of moderate, or more rarely, of small size. Hyrtl (Denksckr. Ak. Wiss. Wein. x, 1855, p. 49) lias recorded a rudimentary accessory branchial organ in one species of this genus from Brazil, Clupea aurea, Agassiz. This genus has been subdivided in accordance with its dentition, but as the teeth are small and deciduous, such a procedure is open to very great objection. In the ensuing British species there are two distinct forms of serrative along the abdominal edge, examples of which are well seen in the herring and in the sprat. In the herring, Clupea harengus, and in the pilchard, C. pilchardus, the scales along the abdominal edge do not pass across from one side to the other, but are divided by an interspace in which are the scutes. These scales may quite overlie and conceal the scutes, the latter not being formed by the coalescence of the scales from the two sides of the body. In the sprat, Clupea sprattus, and both the shads, C. alosa and C. finta, we find that the scales along the abdominal edge pass across from one side to the other, and in the middle line are produced with a tooth-like or spinate process, which pertains equally to the scales on either side of the body. Uses. As food, either fresh or preserved, also for the production of oil. Geographical distribution. Cosmopolitan, many forms ascending into fresh waters, where some now permanently reside. 1.

Length of head 5 to 5^, of caudal fin Q\, height of body 4| to 5 in the total length. Eye situated half in front of the middle of the length of the head, and with an adipose lid on either side. Lower jaw prominent ; the upper somewhat notched in its centre ; the hind edge of the maxilla reaches to beneath the middle of the eye. Opercles smooth, and destitute of radiating striatums. Teeth small deciduous ones on the jaws, a patch on the vomer and also on the tongue, while generally minute ones are present on the palatines. Fins the dorsal commences midway between the end of the snout and the base of the caudal fin ; the ventral is inserted on a line beneath the centre of the base of the dorsal fin. Scales there are 13 rather soft scutes posterior to the base of the ventral fin, along the abdominal edge, and which are partially concealed by the neighbouring scales from either side of the body, which more or less overlap them. The air-bladder has an opening on its lower side at about its centre, where a long but narrow canal forms a communication with the end of the stomach ; it has also another orifice on the left side near the vent,* which canal is lined with a silveiy pigment to within a short distance of its termination. The vessels of the air-bladder being scanty, gas is not secreted, but air believed to be swallowed. In some specimens at Aberdeen I perceived the food in the stomach covered by a mem- brane as in the pilchard, but of a finer consistence. Colours of a rich blue or green along the back, becoming lighter on the sides and beneath, where it is shot with purple, blue, and gold lines. Lower jaw with a black tip. Varieties. There are considerable variations in the proportion of different, races even from adjacent localities. Some of them have been considered species. Names. Hairing, Anglo-Saxon (Herr, or heer, "an army"), or from the French hairang, an old term for a troop or army ; cuddy legs, " a large herring ; " corphun, herring cobs or young herring in Northumberland, where * See figure in Weber "De aure et auditu." etc. pars, i, 1820, t. vii, 63. 14 210 PHYSOSTOMI. they are likewise termed sill-shag. Sgadan, or scattan, Moray Firth. Small ones not larger than a sprat are termed sills, or sile ; fat herrings destitute of roe, maties, or matties, a corruption of the term "maiden," or those which have never spawned. Full herrings are those possessing a well- developed milt or roe ; slwtt en-herrings, or spent fish which having just bred, are very inferior ; it is likewise a term sometimes applied to such as have been gutted and dried for keeping. Green herrings is a term sometimes employed for " fresh herrings." Red-fi?ined-herrings are known as wine drinkers in Scotland, and as loaders in Norfolk and Lincolnshire, while in the western counties they are called Icings and queens. Overday tarts is applied by costermongers to such as have remained unsalted for over twenty-four hours, and consequently are dark red about their fins and gills, due to extravasated blood. A " blown herring " is termed, according to Halliwell, a toio-bloiven in Suffolk. A gut-pock-herring in Scotland is one which has its stomach distended with small crustaceans, or other food. A red herring, or a black herring are trade terms for particular descriptions of cured fish, while the former is also known as a Norfolk capon, and sailors usually designate it as a sodger, or soldier. Bloaters used to be applied to herrings which were smoke-dried but not split open, from " bloat," to dry by smoke : kippered herrings, such as are split and salted. White herring generally implies a fresh herring, but in the north pickled ones are sometimes thus termed. In Scotland the highest brand is given to mazy herrings, or those full of roe ; and what are known as crown-fidl ; those which have not yet developed ova or milt as matties, such as have spawned as shotten, but which find a ready sale in the great continental markets. Local name of young yaivling and Britt ; scuddawn, Irish. Pennog, yfgaden, Welsh ; Be Blaring, Dutch ; Be Haering, French. At Great Yarmouth 4 herrings make 1 warp; a large basket containing 100 is termed a sivill, or long take, 132 ; a last contains 13,200 fish. A cran in Scotland consists of 37i imperial gallons, and generally contains from 900 to 1000 herrings ; a barrel holds about 800 ; a maize, or mease, 500. A cade, or barrel of herrings, appears to have contained 600 in the middle of the 15th century. Habits. The herring is a gregarious, lively fish, a rapid surface swimmer, but somewhat timorous. Whole shoals, it is asserted, maybe scared and turned from the course they had intended to pursue. The wake of these fish is often marked during the clay time by long lines of gulls and sea birds hovering above them and occasionally swooping down upon some as prey ; while at night time, especially if very dark, a slight gleam, " brimming," or "flame," is seen on the surface of the sea where the shoals are. But the herring is not always to be found at the surface, for it seeks its food at any depth where it obtains the best supply ; it may even sink down to the bottom, provided such be not too profound, while it is not uncommon both for it and the mackerel to be captured by the beam-trawl. Thus, in the autumn of 1859, more than 1000 large and full herrings were caught off Lowestoft in a beam-trawl net, and in the spring of 1870 upwards of 5000 shotten herrings were similarly taken at the Well Bank off Great Yarmouth, and in March, 1881, a large number of both shotten and full herrings were thus taken on the Brown Bank (De Caux). It has been remarked along our south and south-west coasts that herrings and pilchards do not intermingle. The noise made by herrings when captured is peculiar, and has been likened to various things to the cry of a mouse, to the word " cheese," a sneeze, or a squeak, and may be occasioned either by the escape of air through the posterior opening of the air-bladder near the vent, or else, as seems more probable, by some movement of the gills and gill-covers.* The food upon which herrings subsist has been variously characterized, but is gerernlly held to consist of minute shrimp-like crustaceans, often of forms belong- :he same division as the common Cyclops of our fresh waters. It is i fc they exist on very varied forms of animal life, and are probably not provided they can obtain sufficient. About the middle of February, !, I found that some from the S.W. coast had been feeding on Annelids; from it has been asserted tbat it is possible to blow air from tbe stomach into the air-bladder. CLUPEIDJE. 211 the same locality in the middle of May their stomachs were crammed with sand launces, Ammodytes, some of which were up to 2j inches in length, and as many as nineteen were inside one herring, while the sand-launces in their turn were full of the remains of Crustacea. A month later from the same place, and captured about eight miles off shore, the food had again changed, and consisted almost entirely of the young of a very rare gobioid fish, Grystallogdbius Nilssonii, the largest of which was 1^ inches long, there were likewise a few young herrings and sand-launces. Goodsir (Edinburgh New Philosophical Journal, July, 1843) gives the result of his examination of the Maidre, or food of the herrings in the Firth of Forth, with which the stomachs of the fish were found to be filled. Cirripeds, Crusta- ceans, and Acalepha were detected, of which crustaceans were in the largest number, and consisted of masses of Amphipoda and Entomostraca. Among the Acalepha the different species of Berooe were seen in the greatest numbers. Off Lofodens Sars found the sea swarming with microscopic animals, especially small crustaceans termed " herring food," Calanidce, chiefly Calanus finmarcMus and Temora longicomis. Carpenter writing upon what they consume in North America, remarks that their food sometimes consists of smaller fishes, but generally of more minute animals, especially Entomostraca and Radiolaria, of which small reddish-brown aggregations are often found floating in the waters which they frequent. H. Widegren observed in Scandinavia that the food of the young as well as of the grown herring consists chiefly of small crustaceous animals, invisible to the naked eye, which are found in enormous quantities in the sea, both in shallow and deep water, and may be detected by straining water through a straining cloth. Their quantity varies at different seasons, and during a change of temperature at different depths. Axel Broeck (Tids. Fisk. Kjobsch. i, p. 154, or Wiegm. Arch. 1862, p. 72) describes the various kinds of food on which he considered this fish subsisted. Breeding herrings do not feed to the extent those not in this condition do, but they do not invariably cease feeding, as some authors believe. In an aquarium it was found (Zool. 1876, p. 4856) that the young or whitebait's diurnal and nocturnal movements were very dissimilar : in the former period they were quiet and uniform in going round their tank in one shoal, but at night the shoal was broken up, each fish taking an independent course for itself, darting about from side to side, striking against the rockwork with effects fatal to themselves, and which was only stopped by placing a dim light to illuminate the outline of the rockwork. Then they are most ravenous. Herrings live in an aquarium provided while being captured their scales are not rubbed off, and Mr. Jackson suggests that the best plan is to dip them out of the sea in a bucket or can, and subsequently allow them to swim into the tank they are to occupy. He invariably observed that they swam round and round their place of confinement in a circle from left to right. Occasionally one might turn for a moment, but it speedily resumed its place, and he never perceived the shoal to swim in a contrary direction. Migrations. Many theories have been broached to account for the migrations of the herrings, it having been formerly supposed that they yearly changed their residence from the poles to southern waters. Even now some consider that it is not, strictly speaking, migatory, that is, that it does not travel comparatively far from the locality in which it was hatched, reared, and came to maturity, but simply changes from shallow to deeper water, in accordance with temperature and the supply of food. One proof advanced being that certain definite varieties are present in certain waters. Where they conceal themselves is certainly remarkable, thus along the Devonshire and south-west coast of England, Mr. Dunn observes that should a gale spring up numbers are taken in nets purposely anchored parallel to the shore, and that they are meshed on the land side, although this locality had been unsuccessfully swept by seines and nets a very short time previously. That herrings, in common with other species of the family, occasionally disappear from one locality, sometimes re-appearing in another, is well known, to account for which many surmises have been made. From 1690 to 1709, a very 14 * 212 PHYSOSTOMI. extensive herring fishery existed at Cromarty ; about the latter year an immense shoal was driven ashore near the town : they left the vicinity in a single night and for upwards of half a century no shoals re-appeared. Still this may have been simply a coincidence. Many reasons have been adduced in order to account for these fishes deserting certain localities. In Long Island, one of the Hebrides, it was asserted they were driven away by the manufacture of kelp, although kelp fires did not drive them away from other places. The firing of guns, or an old Highland idea the shedding of blood. Steam-boats have been supposed to disturb the shoals. The two main objects of migration would appear to be seeking some locality where eggs may be safely deposited for the species to be continued : or else a search for food in order to maintain the growth and existence of the individual. But it would seem that fish may seek new ground, due to that they usually reside in becoming unsuited from any cause (see page 218), as absence of food, or constant attempts at their capture by incessant netting. If, having selected waters further from the shore than formerly, the ova were deposited and hatched, it does not seem unreasonable to suppose that the progeny would locate themselves where they were reared. In time, perhaps, this new location might be found unsuited, and the shoal return to the spot they first inhabited, and where possibly a more abundant supply of surface-food exists. Respecting the effect of temperature and various meteorological conditions of the atmosphere as affecting migrations and captures, so little has yet been ascer- tained on these points that I think it better to refrain from speculating upon them. Fishermen assert that prevalent winds are a cause of migrations, and if so this is probably effected through acting on their food. Also that unusually severe and long-continued xrost during winter and spring induce movements among large shoals, and bring them nearer in shore. Seasonal changes, however, doubtless have an effect in hastening or retarding the advent of herrings ; while diurnal variations may likewise be coincident with the bathymetrical depths at which they are found ; storms may drive them from shallow to deeper water ; while the herring season commences and also terminates earlier in the north than it does in the south ; but much more than this facts scarcely warrant us to assume. The Scotch Meteorological Society observe that the results of examining the daily register of thermometers used in twenty fishery districts on the east coast, go to show a close relation between the fluctuations of the catches and changes of temperature, wind, sunshine, cloud, thunder, and other weather phenomena. Maximum catches having been recorded when the temperature of the sea was about 55"5 degrees, while thunderstorms if widespread were followed for days with small catches over the area which had been covered by them. Mr. Cleghorn concluded an interesting report upon these fisheries with a comprehensive summary. Some of his conclusions were as follows : That there were fishing stations some years ago on the Scotch coast which are now exhausted, a steady increase having taken place in their produce up to a certain point, then violent fluctuations and finally extinction. The races of herrings near our large cities have disappeared first, and in districts where the tides are rapid, as among islands and in lochs. Where the fishing grounds are circumscribed the fishings are precarious and brief ; while on the other hand extensive sea-boards having slack tides, with little accommodation for boats, are surer and of longer continuance as fishing stations. I will now refer to the herring fisheries along the north-east and east coast of Scotland respecting which we are told that, " at the beginning of the present century herrings were so abundant along the north-east coast of Scotland, and came so close in shore that numbers of them were caught by people standing upon the rocks having no other instrument of capture than baskets tied on long poles," a condition of affairs which hardly applies to the present time. At Wick, the largest race usually arrives with the new year, remaining until about March and then disappears. Mr. Reid found in January, 1882, that some were a foot in length and thick in proportion, but all were full of milt or roe. The next herrings come in May or June in the shape of a few small ones of little value as CLUPEID^E. 213 food, although useful as hait for other fishes, and which appear to be the forerunners of the summer fish, as they grow better, larger, and fatter as the season advances until they are in perfection about July and August, spawning about the end of the latter month or early iu September, after which they disappear until the succeeding January (Reid MSS.). If we turn to the Herring Fishery Report of 1878, we are informed that " it is a very remarkable circumstance that the yield of the fishery at Wick began to decline at the very period at which the produce of the Aberdeen- shire fisheries began to increase " (lxiii). Here Mitchell, who wrote in 1864, observed they are at first so small that the nets cannot catch them, but they begin to be of sufficient size in July (at this time the mesh of the nets was not less than one inch between knot and knot).* In the fourteen years from 1849 to 1862, 1003 boats were annually employed in fishing at Wick with an average catch per boat of 133 barrels. During this period no winter fishing was carried on : it now commenced, and in the fourteen years from 1863 to 1876, 885 boats were annually similarly employed, and the average catch per boat was 108 barrels. Mr. Reid tells us that in 1883 great success has again attended the Wick herring fisheries in 1880 (the heaviest fisheries), the average to the same date (end of August) was 170 crans a boat, but in 1883 it has risen to 230 crans average to the 518 boats, but the fish were at least 70 miles from land. Further to the south, however, a different account was given at the same date, for after an exceptionally poor season the herring fishery at Aberdeen was brought to a close in September, when an average catch of 89 crans for 463 boats was announced, as against 166| for 433 boats last yeai\ Fish having been scarce and the weather unfavourable. The herring shoals further north have been much larger, and less distant from shore. It was noticed that the Wick Chamber of Commerce for some years gave a premium to the fisherman who landed the first herrings of the season : thus fishing gradually changed from July to the third week in June, the quality at first being small and mostly only fit for bait. This, it is stated, prematurely disturbs the shoals and injures the future prospect of the fishing. f Herring shoals appear on the north-west coast of Scotland at the beginning or middle of May when during that and the subsequent month they are mostly " matties." The great fishery there is in the Minch between Long Island and the main land, continuing until the commencement of July. While on the east coast the chief fishery begins about the middle or end of July until the end of September, the fish being full of roe, while the fishery at Loch Fyne and the south-west coast of Scotland coincides with that on the east, the fish likewise being in a similar condition. Off the coast of Ayrshire on the Ballantrae Bank the great fishery is during February and March. A short supply of summer herrings, observes Holdsworth, has been frequently accounted for by the preceding fishery having been largely worked. On the other hand it has been contended that the summer fish are often as abundant as they ever were before the spring fishery came into fashion. Recent experience, however, does not support this statement, as with a more or less successful series of spring fisheries, the summer herrings have been exceedingly scarce for the last seven years. (Deep-sea Fishing, 1873, p. 123.) In the Moray Firth (Gordon, Zool. 1852, x, p. 3480) these fish are generally Bought for during six weeks subsequent to the middle of July. They gradually move westwards and congregate on the far-famed Gwillam Bank, about half a square mile in size and opposite the Bay of Cromarty. A storm sends them away and they do not return that year. About the middle of August they swim lower in the water and generally disappear in September. He likewise alludes to winter herrings, a stronger and larger variety with fewer scales. In looking at * M. De Caux observes that for the purpose of capturing herrings the mesh of the nets since 1864 has diminished off the Norfolk coast to forty or forty-four to the yard: ten to twenty years ago five-sixths of the catch were full fish, but for the last ten years the proportion has not been above two-fifths, due to the change in the mesh of the net; these immature herrings will take the salt but they will not keep. f The same opinion seems to have found favour at Peterhead, Aberdeen, and Montrose, that the early fishing has a bad effect on the off-shore banks iucreased by the repeal of the enactments against garvie fishing, which occupation commences in November and occasionally lasts until March. 214 PHYSOSTOMI. the conformation of the Scotch coast we observe on the west numerous narrow lochs, whereas on the east we perceive three large firths. From some cause it is evident that the augmented captures of late years have been among fish out at sea, as 60 to 80 miles or more from the coast. The Yarmouth herring fishing in 1881 commenced June 16th, but the fishing there and at Lowestoft generally extends from October to December 16th, during which period nearly 218 millions of fish were delivered at the wharves, which at the wholesale price of 15 a last, shows a total of 250,000. Along the Devon- shire coast in 1880 this fishing commenced about November 13th, and a fortnight earlier than in 1879 (as was likewise the mackerel fishery). In Devonshire and Cornwall there are two annual migrations of herring. The first, or large herring, with undeveloped roe, matties, approach the coast in May or June, a few being secured in the mackerel nets, while some continue to be so taken until the mackerel fishery ceases, about July. About the same time, May or June, quantities pass up St. George's Channel to the Irish Sea, and are supposed by fishermen to re nain in deep water. In June or July they proceed in a northerly direction, very few remaining off Cornwall, and do not return there until October or November, or even as late as December, their migration towards the coast occurring especially if the weather is fine. Should a storm arise they at once retire to the deep and do not reappear off the coast until fine weather has recommenced. By February or March they become " shotten," poor and thin. Besides these large herrings there is a migration of the smaller ones early in November which, as Mr. Dunn has observed in Cornwall, migrate to the west at the extreme northern extremity of the county. Various schools pass by Port Isaac, New Quay, St. Ives, around Land's End, and eastwards into Mount's Bay or by Falmouth and Mevagissey, finally stopping at Bigsbury Bay, the bottom of which is rocky, uneven, and covered with flexible corals (Gorgonia), and here they congregate until the January spawning season. Means of capture. For the purpose of indicating where the shoals of herring are the presence of whales or flocks of sea birds are often useful, but if no such indications are present the nets are frequently shot at a venture. Formerly it was the invariable custom to cast their nets by night for fear of scaring the fish, but now this rule is being broken by some vessels. On very dark nights the phosphorescence of a shoal if near can be readily perceived, in fact off the east coast the majority of fishermen assert that they always wait until " the flame " is visible, and consider that they are able to tell the difference between " full " and " shotten " fish, a shoal of the former swimming close together in a compact body, whereas in the latter the individual fish are constantly dashing about. In some places the shad is termed the damon herring, and popularly believed to lead the shoals. In fishing for herrings a number of drift nets are joined together and these are termed a " fleet," the length of each being about 20 yards, while from 101 to 181 comprise a fleet, the length of which off the east coast vai'ies from 1^ to 2 miles. The Scotch fleet consists of 48 pieces, each 40 yards long. They are made of cotton, which is found much more destructive than hemp which was formerly employed. The mesh should be of sufficient size to allow the herring to obtain entrance for its head as far as its gills. During the autumnal herring season it has been computed that there are frequently from 8000 to 10,000 miles of nets in the North Sea at one time. In 1809 it was enacted that the size of the mesh should be 1 inch from knot to knot or 4 inches all round ; and in 1839 France signed a convention with Great Britain constituting it the law for both countries ; this was abrogated in 1864, and in 1868 the regulation was repealed. Since then the fishermen have reduced the size, and off the east coast the mesh has become from 40 to 44 to the yard, catching large fish by the snout but allowing them to drop out and be lost. Shoals of herrings have occasionally been met with of such considerable size that they have broken the warp rope of the nets, and the whole of the gear has been carried to the bottom. As herrings are caught at sea thoy are put into the hold and mixed with salt : CLUPEIDiE. 215 ice may likewise be employed for this purpose. The fish first removed are the most valuable, as having been subjected to less pressure and a purer atmosphere. As a rule when the sea is calm and the temperature high, the takes become more or less spoiled before they can be landed ; in some places the use of steamers has obviated this, and communications between the fishing fleet and the shore may be maintained, as at Montrose, by the employment of carrier pigeons. If the steamers were furnished with a double set of gear so that the tanks containing the captured fish could be removed at once and fresh ones substituted, a tide would be gained to the manifest advantage of the fisheries, as the steamers could at once return to the fishing fleets. M. De Caux has given it as his opinion that the alterations in the fishery laws have been so mischievous that now, although the killing powers of drifters in the same district (Yarmouth) have increased six-fold, the quantity of herrings captured has augmented but slightly, even if it has at all. On the Devonshire and Cornish coasts drift nets and moored nets in the bays are employed occasionally up to the end of February ; even as late as the middle of March, 1882, small boats were still capturing them with drift nets off Plymouth, but the moored nets had been laid up until the next season. Along the Cornish coast there is no special fishery in the spring for herrings ; some stragglers are taken in the mackeral nets and subsequently in the drift nets employed fishing for the early shoals of pilchards in July and August, when they are chiefly found in deep water. Boats from Mount's Bay, Cornwall and St. Ivea leave for the Irish shores about the first week in June and rendezvous at Howth to the north of Dublin Bay, where the best fishing is about the last week in June or the first week in July ; subsequently it generally decreases and the boats go north. Herring fishing may frequently have to be suspended, or even entirely given up, due to stormy weather preventing fishermen from venturing out to sea. In 1880, the Scotch fishermen had a most successful year, but it was remarkable that the greatest amount of success attended the efforts of the drift-net boats. The trawl-net boats were continually coming in clean, and, with rare exceptions, were very poorly fished until the recent cold, frosty weather set in, when some splendid takes were secured, yielding to each crew for one night's fishing from 100 to 200. Such a marked difference between the two modes of fishing has never been observed before, and as yet no real cause has been assigned for it. The " dand} r -line " is used in herring fishing at Peterhead, during April, May, and June. A piece of lead about 1^ lb. in weight is attached to a line, which carries at short intervals transverse pieces of whalebone or cane, having unbaited hooks at either end. Herrings are such hungry fish that they fly at the naked hooks and are easily caught in this manner (Anglers' Note-book, p. 48). The hooks must be kept moving about and the water should be a little discoloured. Along the coasts of Down and Antrim, large quantities used to be taken by means of hand-lines. The hooks being dressed with feathers, and the time of fishing being evening or sunrise (Thompson). Neill remarked that off the Scotch coast they were often taken on hooks baited with limpets. Off Northumberland and Durham, we are told that herrings used only to be fished when in their prime, or from July to September : now from 100 to 150 large boats come from Scotland every spring, and young herrings are captured from May right on, but they are poor and tasteless (G. Bo well, Land and Water, July, 1881). Mr. Southwell, off Norfolk, considers that there can be no two opinions as to the small size and inferior quality of the " spring herrings," and thinks that it is a matter of regret that they should be taken at that season. Superstition enters largely into the composition of fishermen, and in the Banff Journal of 1855, it was recorded that the herring fishery being very backward, some of the fishermen of Buckie dressed a cooper in a flannel shirt, with bars stuck all over it, and in this condition he was carried in procession through the town in a hand-barrow. This was done to bring "better luck" to the fishing. A century or two ago not merely effigies, but living men and women, were burnt on suspicion of casting a blight on the herring-fishery ; even at the present day it is common for whale-fishers to burn an effigy in order to " bring luck." If a ship has fallen in with few whales, the crew attribute their bad fortune to having some 216 PHYSOSTOMI. unlucky individual on board, and by burning his effigy they believe that his malign influence is got rid of. The most unpopular man in the ship is generally pitched upon as the offending party. Sometimes two or three "pictures" are burnt, one after the other, if luck is very bad. The practice is a very old one, and is said to have taken its rise from a similar custom which prevailed among the herring-fishers of Banffshire, by whom it was introduced on board of the Peterhead whalers. In Norfolk (Notes and Queries, October 7th, 1865) we are told existed a fancy that fleas and herrings come together. "Lawk, Sir," said an old fellow near Cromer, " times is as you may look in my flannel shirt and scarce see a flea, and then there ain't but a very few herrings ; but times that'll be right alive with 'em, and then there's certain to be a sight of fish." Low, in his tour through the Orkneys (1774), says that as much as 50 was paid for the first barrel of herrings of the season that arrived from Shetland, this first instalment of the herring market being regarded there as medicine. Red-finned ones appear to be considered as omens of success on some parts of our coasts, and Mr. De Caux tells us that as soon as one is perceived, it is taken from the net, carefully prevented from touching anything made of wood, and passed round the scudding-pole as many times as the fishermen desire to get lasts of herrings at their next haul. A Manx man going herring fishing dares not proceed to sea without taking a dead wren in the boat for fear of disasters or storms. There exists a tradition of a sea-spirit that haunted the herring-tack, attended always by storms. Finally it assumed the form of a wren and flew away. It is imagined that the presence of a dead wren makes all snug (McTaggart). Breeding. The period at which the herring breeds is subject to great diversity, inasmuch that some persons have questioned whether it may not do so twice in one year. At Wick on the north-east coast of Scotland, Mr. Reid informed me (January 18th, 1882) that early in January this year they were in a spawning condition but no shotten ones as yet to be found, while they again spawn there in August and early in September. The same has been observed in the Moray Firth by Gordon. Herrings taken on the Ballantrae Bank off the Ayrshire coast in February and March are either spawning or shotten. Herrings spawn on the east coast of England and Scotland (taking the extreme dates) from the latter end of May to December, that is, measuring from the Shetlands to the North Foreland ; these Ballantrae herrings never spawn in August, but, on the contrary, begin about the 1st of February, and the spawning goes on till the 1st of April. This spawning bank is ten miles long and two miles broad. The average depth is ten fathoms at low water (Buckland). On January 5th, 1882, I found that most of the herrings in the fish shops and which had been received from Cornwall were shotten, others were full of milt or roe. At the end of August, 1881, many were in full roe, and on December 13th I first saw some shotten* ones, but was informed some had been received previously. Mr. Dunn observed that all the herrings which visit the south coast of Devonshire late in November, throughout December, and early in January are in spawning condition. Six hundred thousand were landed in Plymouth one day last week and the spawn was almost ready for extrusion in the whole of them (Land and Water, Dec. 24th, 1881). A month later he found at Mevagissey that the spawn was running from them. He considers that there are two herrings which spawn on the Cornish coast, the smaller in December and January and which is not so regular and certain a visitor as the larger one, which spawns in February and March. The lesser ones seem to migrate along the coast, the larger ones to come from the deep sea. Andrews (Feb. 14th, 1882), writing from Swanage, in Dorset- shire, stated that he had two dozen brought to him five da} r s previously all full- roed, and many on the 14th, while the pier-master informed him that the first signs of spawning were noticed yesterday, and the fishermen reckon, as a rule, upon taking full fish more or less up to March. Mr. Wilcocks (Field, Feb. * M. Bertrand, in his article on Alose, published in 1776, remarked that" it appeared certain that in the English Channel many herrings begin to spawn about November 25th, although in certain years some are still i'ound full in February." CLUPEID^E. 217 25th, 1882), remarked from Plymouth that the herrings have not yet left the coast, and many among them have not yet spawned. It is evident that off Great Britain there are two chief periods for spawning, but that at various places some spawning fish may be captured at any month throughout the year. The autumn breeding time would appear to be the most extensive. The number of eggs which have been found in a single herring has varied from ten to thirty thousand, when shed it sinks to the bottom of the sea, while along with it is a glairy fluid which enables the ova to adhere to any object with which it may come in contact. Ropes or nets drawn throngh herring spawn become thickly coated with it, and large quantities are brought on to the decks of fishing boats. Nets set in water where spawn exists in a very short time become heated similarly to what occurs when heavy catches of fish have been made. The locality selected is often over rough ground, while sea-weed may be found covered with this adhering spawn. In the Baltic and localities where the water is brackish and almost fresh they have been observed to select two or three feet of water for this purpose. It seems highly probable that they deposit their spawn wherever they happen to be, as herrings in which this was exuding were taken at least forty miles out at sea, or in forty to fifty fathoms of water, while it is very attractive to other fish especially cod. Spawning fish are captured in shore and far out to sea at the same time, while shotten and mazy ones are frequently found together. The escape of the young from the eggs, either in spring or autumn, can be considerably delayed by keeping the water very cold, while its saltness or reverse* exercises no appreciable difference. Three to four weeks has been suggested as the probable time at which hatching normally occurs after extrusion. While if these eggs are heaped together they become mouldy. Meyer found that in a few days after being hatched they commenced preying upon microscopic forms existing in the water, after a month on small Crustacea, and at the end of the third month they were a little over 1| inches in length. Beyond five months he could not keep them alive. The young, known as whitebait, swarm along our shores in certain localities, sometimes to a great extent mixed up with sprats, at other time in independent assemblages. Mr. Stevenson (Mansion House Street) hatched some. The spawn was obtained November 10th, 1870 ; by the 17th the eyes and movements of the young fish were plainly visible through a hand-magnifier, and on the evening of the 24th (fourteen days after they had been taken from the parent and impregnated) many shells were found empty, but only one little one could be seen, for they are so minute and transparent that there is but little chance of finding them in a large body of water. By enclosing the ova in a suspended muslin receptacle in the tank several more were hatched out by the 29th. Dr. Meyer, respecting the experiments made in the North Sea, observes that no one has succeeded in rearing herrings from artificially fecundated eggs, owing to the impossibility of arresting the formation of hyphae of some fungus, and the difficulty of obtaining suitable food : very soon after the yolk was consumed they died. H. Widegren, in Scandinavia, found that certain races of herring, particularly the larger ones, spawn near the land on a bottom overgrown with sea-weed. If this bottom is made unfit for spawning by taking up or destroying the sea- weed, either by nets or any other way, the herring becomes obliged to migrate to more suitable places, and consequently deserts the inlets where he formerly visited regularly. " By experience gained in Bohuslan and other places, it is proved that the herring is extremely sensitive in this respect, and deserts old spawning places entirely if their character is changed." Vegetation ought not to be disturbed nor refuse cast into the water. It now becomes necessary to consider, What do we understand by whitebait, or " white bite" as it has been termed ? Here we must first seek for the origin of * In the Baltic the German Commissioners ascertained that with the water at 53 the eggs hatched in a week, whereas at 38 they took six weeks, while raising the temperature above 53 did not quicken the hatching process. 218 PHYSOSTOML the term, and at the outset I am inclined to admit that such appears to be lost in obscurity. It is stated that at the funeral feast of the founder of the Charterhouse in 1612, six dishes of " Whitebait " were included in the bill of fare. If we refer to Pennant's British Zoology, vol. iii, p. 371, 1776, we read as follows : " During the month of July there appear in the Thames, near Blackwall and Greenwich, innumerable multitudes of small fish which are known to the Londoners by the name of whitebait. They are esteemed very delicious when fried with fine flour, and occasion, during the season, a vast resort of the lower order of epicures to the taverns contiguous to the places they are taken at." Pennant stated they belong neither to the shad nor the sprat, nor are they the young of smelts, but bear a great similarity to the bleak, to which fish he appended them, although with doubt. Donovan (1808) obtained as whitebait the young of the shad, and calmly expressed his opinion that Pennant never saw a whitebait, or, if he did, his examples were bad, or his investigations hasty and negligent, while his figure conveyed no just idea of the fish. Next we have Yarrell (1828), who considered that both Pennant and Donovan were in error, as he saw in these fish a new species of Clupea, which he termed Clupea alba. M. Valenciennes (1847) went still further, instituting a genus (Bogenia) for its reception, while he remarked that some young sprats were captured along with the true forms during the months of April, May, and June. Dr. Gunther did not coincide with any of the four previous writers, and considered it to be the young of the common herring. It is unquestionable that the true whitebait belongs to the herring family, but are such mature forms as asserted by Yarrell and Valenciennes ; or immature fish, as believed in by the majority of inquirers, and as such were formerly protected by legislative enactments ? In this investigation we must not lose sight of the fact that the herring family, more especially among the species composing the genus Clupea, possess many pelagic forms, which live together in large assemblages or schools, the young of which but rarely enter brackish, and never as a rule fresh water. Another peculiarity is that, the teeth being small and deciduous, a considerable diversity as regards their existence may occur in examples of the same species. Are whitebait mature fish ? This question has been answered by most investigators in the negative, by Yarrell in the affirmative, while fortunately the specimens of this last author, being still in the British Museum, are open to re-examination. All are certainly the young of the common herring. Yarrell remarked that these fish are taken in the Thames " from the beginning of April to the end of September . . . and specimens of the young fish of the year, four or five inches long, are then not uncommon, but mixed even at this late period of the season with others of very small size, as though the roe had continued to be deposited throughout the summer. Yet the parent fish are not caught." I have now a fine series of whitebait captured during the months referred to by Yarrell, and from the same locality (the Thames), and these I now propose enumerating, premising that, as the migrations of members of the herring family are variable, occasionally forsaking their usual spawning grounds, it does not appear improbable that one species may have left and given place to another, to be again changed to the original form on the return of the water to some condition which suited its first occupants. Thus Yarrell observes : " Formerly great quantities of the Twaite shad were caught with nets in that part of the Thames opposite Millbank, Westminster." At Teignmouth in Devonshire, in August, 1882, all the " britt " or whitebait were young of the herring, while in August, 1883, every one were small sprats. I examined 138 examples of whitebait from the Thames, taken during the months of May and June, 1878, the longest of which was 2\ inches ; out of these about one in ten were sprats, the remainder the young of the herring. In August I examined forty-six examples from 2 to 3| inches in length ; out of these twenty- four, from 2 to 2" 7 inches long, were sprats, and twenty-one, from 2*8 to 3 inches long, were young herrings, these latter now commencing to grow to a larger size CLUPEID^E. 219 than their smaller relatives, the sprats. In October, out of forty-one examples from 2^ to 3^ inches in length, all were herrings. It appears that both sprats and young herrings find their way into the London market as whitebait. Some inquirers may obtain one species, some the other, while a third may receive both forms, in accordance with the locality the fishermen were working their nets and whether schools of one or both were present at the time. Of the thirty-one examples of "winter whitebait" received from the Medway, twenty-six varied from 2 to 4| inches in length, the larger ones possessing well- developed roe ; all these were sprats : the remaining five were young herrings from 5 to 7\ inches long, the largest having slightly developed roe.* How are these young fish to be distinguished ? may be asked, and to this question a very simple reply will suffice. The sprats have sixteen to eighteen rays in the fin of the back, and seventeen to eighteen in that behind the vent. The ventral fins are situated beneath the first rays of the back fin. They have forty- seven or forty-eight vertebrae, no teeth in the front part of the palate (the vomer), and in a single or double row along the tongue, while internally they only possess seven or eight caecal appendages at the pyloric end of the stomach, while the edge of the abdomen has very sharp points, entirely dissimilar in the two forms as I have pointed out (page 209). The young herrings have seventeen to twenty rays in the fin of the back, and sixteen to eighteen in that behind the vent. The ventral fins are situated beneath the middle rays of the back fin. They have fifty- six vertebrae, teeth in the front part of the palate (the vomer) and in a long oval patch along the tongue, while internally they possess seventeen to twenty or more caecal appendages at the pyloric end of the stomach. The keeled abdominal edge is not nearly so sharp as in the sprats, while the scales do not fall off the body quite so readily as in the latter species, in which but few are seen on the sides in captured examples. Due to the position of the back fin fishermen can recognize these two forms by holding them up by the dorsal fin, when the sprat trims by the head, but the herring by the tail. That Pennant's was the whitebait of the present time there can be but little doubt, and likewise that it was the young herring. It is also certain that Donovan's figure is that of a young shad, the immature of which, if in sufficient numbers, would do as well as those of the herring or sprat served up as whitebait, while I certainly possess the young of these last two forms which I have received as this fish. During the summer and autumn of 1874 several hundred small whitebait were imported to Manchester from Colwyn Bay, North Wales. During the first eighteen months of their captivity they grew to at least half the size of a full- grown herring, with which species there was no gainsaying their identity (Zool. 1876, p. 4855). Meyer states his grew only to 1^ inches in length in five months. Mr. Sim, of Aberdeen, observes that he found herring fry in the rock pools in great numbers in the months of June and July, all from 1| to 2^- inches long, and which he concluded were from the March spawning, or four to five months old. As these fish arrive at maturity, very conflicting evidence has been adduced respecting the time at which they first breed. Some (as De Caux) have believed this to be well within twelve months, a supposition somewhat confirmed by my examination of whitebait and detecting ova (see above) : eighteen months has likewise been suggested (Mitchell) ; also that they are approaching the expiry of their second year before they shed their first ova (Sim). While some observers believe they spawn twice a year, others as positively affirm the contrary. Hermaphrodites. Yarrell refers to one (Proc. Zool. Soc. 1845, p, 91), as does also Malm, who describes and figures it (CEfv. Ak. F6rh. 1876, pi. v) : likewise J. A. Smith (Journ. Anat. and Phys. iv, 1870, p. 258). Herring fisheries. It would appear from the Commissioners' report that young herrings along the east coast of Scotland were first permitted to be captured in small meshed, sprat, or garvie nets in 1868 : the true garvie being the sprat, Clupea sprattus. Some of the witnesses averred that when garvies are scarce * Yarrell remarked that if whitebait die in fresh water the air-bladder collapses (P. Z. S., 1830, p. 73). 220 PHYSOSTOMI. many young herrings are sent away with them, while it is impossible to take garvies without taking the young herring. One witness asserted having pur- chased thirty barrels of garvies in one day, and found they were all young herrings. My only personal experience consists of some garvies from the north-east coast, most of which were undoubtedly joung herrings. They were about three inches each in length, requiring 288 to weigh a pound. Whilst from Inverness we are informed that in three years ending 1876-77, the Highland railway carried on an average 267 tons of garvies annually to London. I would here venture to suggest that it would be very desirable that an inquiry should be made as to whether or no the cessation of the in-shore herring fisheries has been coincident with the extension of the :arvie fisheries.* There are, it appears, two chief periods when herrings appear off the east coast of Scotland, while the winter, June, and garvie fisheries are partially or wholly new institutions. Whether they have or have not any bearing upon the cessation of the in-shore herring fisheries I have not sufficient evidence to adduce. Still it is by no means impossible that some fishes, especially such as are of gregarious natures, mostly return to the place where they were reared. Respecting the capture of the herrings off the east coast of Scotland, it is evident that the great bulk of the fishing is carried on much farther out to sea than it was a few years since. Still it does not seem at all proved that the in-shore fishing has been neglected, but the probabilities are that the fish are no longer there in sufficient numbers to repay the fishermen's labours. If we take the average capture of herrings as shown in the Scotch Fishery Reports, f we find them as follows : 8 years ending 1816, annual cure, 132,837 barrels.

First of all, one is led to ask what proportion of persons are now engaged in this occupation to the numbers that were thus employed at the commencement of the present century ? Is the augmentation of captures due to increased facilities of capture, larger ventures in fisheries, or simply because the fish are more abundant ? The earliest date on which any confidence can be placed in the returns as to the number of fishermen J employed is from 1825, and I find that the number of barrels of cured herrings has gradually increased from about 379,000 in Scotland and the N.E. coast of England until they have reached to upwards of a million during each of the last two years, while the fishermen and boys have * In Norway it has been found that a diminution of herrings in the creeks has been coincident with an extension of the whale fishery. It is believed the fish escaped into the inlets from their pursuers. The terror of the nets in the inlets was less than that of the whales in the ocean, but these latter being killed the herrings do not now swarm into the creeks. f These returns were from April to April up to 1843 ; those up to 1849 include those of the N.E. of England ; from 1850 to 1868 they include those of the Isle of Man ; from 1869 ihey refer to Scotland only. \ I do not allude to figures handed down prior to the commencement of this century. As, for instance, we are told that in 1667 the Scotch had 800 fishing boats, manned by upwards of 5000 men, engaged in the herring fishery. This includes the line fishing, but the two arc not separated ; the proportions probably continue much the same. >> CLUPEIDiE. 221 increased by almost 4000. The proportion of number of fishermen to barrels of herrings cured has averaged as follows : 5 years, 1825 to 1830, 1 fisherman to 8 barrels of herrings. 5 1830 to 1835, 8 5 1835 to 1840, 9 5 1840 to 1845, 10 4 1845 to 1849, 9 5 ]849 to 1854, 14 5 1854 to 1859, 15 5 1859 to 1863, 15 5 1863 to 1869, 15 3 1869 to 1871, 17 5 1871 to 1876, 19 5 1876 to 1881, 22 The immense value to the community will be seen when attention is directed to the value of the fishing gear in Scotland having averaged 1,263,737 for the last five years, while each barrel of cured herrings is estimated to be worth about 25*. But when we inquire into the gear employed, we are told that cotton nets came into use about 1856, and rapidly superseded the hempen ones. A boat which used to carry 24 hemp nets, 40 yards long, equivalent to 960 yards of netting, now employs 50 to 60 cotton nets each 60 yards long, equivalent to 3300 yards. The nets per boat we are told " used to present a catching surface of 3000 square yards ; they now present a catching surface of 33,000 square yards." The Commissioners estimated when giving the foregoing figures that " each boat has increased its power five-fold." But the amount captured does not appear to have kept pace with the increased killing powers, for if so the fishermen who from 1825 to 1850 while employing hemp nets obtained from eight to ten barrels per man, should now, were the proportions equal, be capturing from 40 to 50 barrels, instead of about 22. It has been computed that there are 30,000 fishing vessels of about 280,000 tons tonnage, manned by 165,000 men and boys, engaged around our islands, and most of which are or have occasionally engaged in the capture of herrings. Numerous trades are dependent on the success or the reverse of this fishery. It would be an exceedingly interesting investigation as to what is the effect on the eggs of herrings deposited in depths over 50 fathoms. This can only be ascertained by a series of experiments carried on in the ocean, as I have already but uselessly advocated. If this deeper water has no deleterious effects upon the hatching of the eggs the question arises whether such has any action on the fry, or if when hatched they are in as good a locality for being reared as if they were nearer in-shore. Lastly, I would remark that if the herrings have, due to changes in our fishery laws and consequent methods of fishing, been unduly interfered with, so that the shoals are now further out to sea than was formerly the case, thus necessitating the employment of larger boats, has not such occasioned a great loss of life ? That going further out to sea to obtain these fish is a necessity is now admitted, while the harbour accommodation remains the same, boats are thus unable to enter during storms and a great sacrifice of life is the result. This is another and most important factor which ought to be taken into consideration when deciding upon the necessity or the reverse for investigating the results which have followed the legislation of the last 18 or 20 years. As food. Herrings are very largely employed as food either in a fresh or cured condition. Of course in different localities these fish may be and often are differently treated. Usually care is taken in selecting and assorting such fish as have to be cured and also in obtaining the services of competent gutters, while the rapidity with which the various processes are carried on, the seasoning of the barrels when such are used, and period at which they are fastened down, all are important factors in the condition in which the cured fish will be found. In the north of Scotland the herrings on arrival are placed in a heap near the troughs of the embers, next they are gutted by individuals who at one cut remove the intestines and gills. They are then " roused " with salt in a tub and lastly packed in layers in barrels, a handful of salt being sprinkled over each 222 PHTSOSTOMI. layer. All broken or inferior fish, or those which have received too small an amount of salt, should be rejected. As the contents subside a fresh layer of fish is added, for the barrel must be kept full. Yarmouth bloaters are variously prepared, but one of the best solutions in which this can be effected is mixing 29 lb. of common salt with 71 lb. of water, in large vats ; in this the herring will float, so they are kept down by wooden battens weighted with bags of salt, which gradually dissolve and keep the solution at its proper density. When the fish have become rigid the pickle is run off and the herrings are suspended in a current of air until they are removed to a chimney and smoked from 12 to 18 hours, the fuel employed being two parts of oakwood, beechwood, and turf. These bloaters will keep four or five days, but are best if hanging in a current of air. Red herrings are bloaters more strongly cured, the pickle having about ^ of its weight of saltpetre added to the salt. They are dried for 24 or 48 hours and then smoked to the requisite tinge. Kippered herrings are such as are pickled, dried, and split down the back almost to the tail fin, showing the back bone, the gills and intestines are removed, they are then cleaned with salt and water, and suspended for a night in a current of air and then smoked until they are of a light brown. They do not keep long. The date of 1794 is given as that in which ice was first employed in Scotland to add to the herrings which were packed in boxes and sent by fast sailing vessels to London. The present railway rates are levied in a most incomprehensible manner on the carriage of fish, rendering their being thus carried, except at a loss, often a matter of certainty; while in Land and Water (August, 1881) we read : " The charge for the carriage of herrings from Berwick-on-Tweed to London being the same as that from the extreme north of Scotland, although the distance is about 300 miles less, several herring buyers have complained of the unfairness, and have taken steps to obtain a revisal of the rate. This week they have sent their fish to London by steamer at a cost of 2s 4a5 per barrel. The railway rate varies from 7s to 9s per barrel." Uses. Largely employed as bait for cod, ling, and long lines generally, and they have, when very numerous, been boiled down for the oil which they contain. Lacepede inquires " what honours are not justly his due who first taught mankind the art of impregnating the solids of the herring with sea salt ?" Unhappily, the subject is so interwoven with discrepancies as to date and nationality that no answer worthy of credit can be given. At the beginning of the twelfth century there were herring fisheries in the Baltic, to which many foreign vessels resorted ; these herrings must, therefore, have been salted ; in fact, in 1155 Louis VII of France prohibited his subjects purchasing anything but mackerel and salted herrings at Estampes. In 1290 part of the dried fish shipped at Yarmouth, in the victualling of a vessel to bring the infant Queen of Scotland from her Norwegian sire, were herrings, and these, of course, wei'e cured. In the time of Edward III, mention is made of some white herrings found in vessels captured by the Cinque Ports ; and in the same reign red herrings are also specified by name, so that both sorts of curing were practised before the time of William Berkelszoon, of Biervliet, in Flanders (he died 1397), who has been credited with the distinction of introducing them. There is, however, no doubt that he greatly improved the methods he found in use, by curing the fish in small kegs instead of piling them in heaps, which so extended the trade in them that Charles V erected a statue to his memory, and, with his sister, visited his tomb, and offered up prayers for his soul ; while Mary of Hungary, during her visit to the Low Countries, paid a more characteristic tribute to his memory, namely, that of eating a salt herring on his tomb. In our own country the herring fishery certainly flourished in the twelfth century, for in 1195, according to historians, the town of Dunwich, in Suffolk, was obliged to furnish the king with twenty-four thousand herrings. Mention is also made of the herring fishery in a chronicle of the Monastery of Evesham, in 709. The herring fair in Yarmouth was regulated in the reign of Edward III CLUPEID^E. 223 by the Statute of Herrings. On the old arms of the town were figured what are proverbially known as " Yarmouth capons," az. three herrings, arg. In 1563 green or fresh herrings were so scarce, that at Yarmouth, the great mart, they sold at an unusually high rate ; a last, or eighty bushels, brought 9. In France, until the close of the seventeenth century, fish diet was scru- pulously observed on fast days. Thibaut VI, Count de Blois, gave annually (by charter, 1215) five hundred herrings to the hospital of Beaugency. Among the extensive charities of Saint Louis to monasteries and hospitals were sixty-eight thousand herrings. In olden times the soldiers engaged in warfare observed their Lent. Thus history informs us that while the English were besieging Orleans in 1428 one of the convoy of provisions destined for their camp was attacked by the Duke de Bourbon. It consisted chiefly of salted herrings, which gave rise to the conflict being called the " Battle of the Herrings." A curious notice respecting the connection of herrings with marriages appeared in the Times (November 28, 1871), showing the results of the Scottish registers. In the return for the third quarter of the year, the registrar of Fraserburgh stated that the herring fishery was very successful, and the value of the catch, including casks and curing, amounted to 130,000 sterling, and the marriages were eighty per cent, above the average. On the other hand, the registrar of Tarbet reported a steady falling off in the fishing at that creek, and consequently the quarter passed without an entry in the parish register. The registrar of Lochgilphead stated the herring fishery to have been a failure in the loch, and this accounted for a blank in the marriage column for the quarter. One registrar, in his return for the quarter, reported marriages in his district "like angels' visits, few and far between." At the fishing villages it might be put more briefly no herring no wedding. Diseases and causes of destruction. Whales, porpoises, seals, members of the cod family, dog-fishes, in short all predaceous fishes, especially hakes and whiting, feed on them from the time of their birth and throughout their entire existence, and in this they are assisted by birds of various sorts. Gannets are occasionally so gorged with herrings that they are actually unable to fly. In the North Sea the cod fishes leave the sea bottom at night time and ascend to the herring nets, from whence they violently pull out quantities of the meshed fish, and at the same time occasion much damage to the lighter kinds of cotton nets, in which they tear large holes. Habitat. White Sea, and perhaps extending into some parts of the Arctic Ocean : the colder to the temperate portions of the Atlantic : the North Sea and the Baltic, in which latter locality they are a small and inferior race. Also the North Pacific. In the Orkneys, Low observed that the Shetland Isles swarm with them in April and later, the east coast of Caithness in August, the Hebrides at the latter end of the year. The Sounds at certain seasons are alive with the fry. I have already alluded to their distribution along Scotland, the west coast of which country is studded with lochs, from which it is asserted they have commenced more or less to absent themselves, while along the east coast, possessing but three large bays or firths, they have latterly forsaken their haunts about 7 miles out to sea, and receded to 20, 30, or even 100 miles. I have also alluded to the distribution of the herring on the British coast, while it is common round Ireland. Along the southern shores of England I have already observed these fish are in diminished numbers. The size to which herrings attain varies. De Caux observes that the largest he has personally seen was 15| inches in length, but that Mr. Utting, of Great Yarmouth, had one which was 17 inches long, but the usual average off our east coast is from 10 to 11 inches, and, if full, weighing from 4 to 6 ounces : a full one, 11 1 inches long, will weigh 8 ounces. Buckland stated that the largest herrings submitted to him were from the Shetlands, the milt and roe were but slightly developed, they were very fat, and as long as 9j inches and 7\ ounces weight. Sim, at Aberdeen, weighed some full ones 12j inches long, and they were only 8^ ounces : the largest example he found in 1880 was 12^ inches, and weighed 9| ounces. It was a full one. 224 PHYSOSTOMI. 2. Clupea pilchardus, Plate CXXXIX, figs. 1 and la, stomach and food. Sardina, Belon. p. 161; Rondel, pp. 217, 218; Gesner, p. 822; Ray, Syn. Pise. p. 104.

In examining the digestive organs one finds the stomach as depicted : the proventricular glands in the aesophageal portion are well developed, while the walls of the pyloric portion are thickened and the mucous membrane is densely studded with glandular prominences. This portion of the stomach, after feeding, is distended by what may be likened to a sausage-shaped mass, consisting of an outer secreted membrane enveloping the food. The air-bladder has the same posterior opening into the progenital canal as recorded in the herring. (See Zoologist, 1882, vi, p. 24, on the digestive organs of the pilchard.) Varieties. In form. It has been asserted that the sardine has the ventral fin inserted below the middle of the dorsal, and the gill-rakers rather shorter than the eye ; but it is merely the young of the pilchard, which latter has the ventrals inserted rather behind the middle of the dorsal fin, and the gill-rakers a little * Giinther, Catal. 1. c. gives ccec. pylori 7, but probably he must have been examining a sprat, the only British Chqiea which possesses such a small number of appendages, and this is rendered more probable as he gives L. 1. 47-48.

In colour it is by no means rare to see pilchards, even ai many as one in five among thousands, sparingly marked with black spots, and which become still more apparent on the scales being removed. In some the eyes are black-ringed, in others white, the former, according to Mr. Dunn's observa- tions, being most numerous in the summer months, the latter in the autumn. Mr. Couch, June 8th, 1868, observed : " I have also obtained a box of sardines from Marseilles, and am rather surprised to find them only so many small pilchards. I cannot find in them any difference from our pilchard, except that they are about five inches long and of poorer quality." That the sardine is the young or small pilchard has been asserted from the time of Belonius in 1553 to the present; it has also been so considered by all modern ichthyologists, and Dr. Giinther in 1868, in Proc. Zool. Soc. expressed his surprise that it was not utilized in the same manner as the sardine. Mr. Dunn, of Mevagissey, appears to have been the first to propose preparing sardines in this country. Names. A dried pilchard in Devonshire is sometimes termed a fair maid, derived from fumado ; smaller forms go by the name of sardines when tinned. Halliwell gives surding as synonymous with the pilchard. In Cornish it is known as hern, liernan, and llean. The term pilchard has been variously derived, some considering it to be from "pittch," an old English word signifying a piece of cloth to wrap round a young child, because these fish were formerly cooked in paper, similarly to red mullets of the present day. It has also been derived from peltzer, a name by which it was known to some early Northern Continental authors. It has been termed a "Looe trout," when impressed on a token struck at Looe in the reign of Charles II. Garvie-herring, Gipsy herring and Grue herring, Scotland. Pennog mair, Welsh. The springing of pilchards out of the water has been termed stoiting (East) or poppling in Devonshire. Habits. Gregarious but very timid fishes, and believed to be easily alarmed by noises.* They congregate in dense masses by day, but as evening sets in spread out along the shore (I am here alluding to St. Austell's Bay), apparently feeding from off the land, and so retire to the deeper waters with the return of the morning's light. At sundown nets are shot outside these feeding-places, thus arresting the shoals in their progress towards the deep sea, while during the daytime these fish are taken on the deep-sea side of the nets. As I have already alluded (note, page 220) to the herrings being driven from the open sea into creeks by whales, pilchards likewise have been known to ascend into brackish water when under the influence of fear. Thus, in 1722, a large number were taken in the Dart at Totnes Weir, having been chased there by porpoises ; and in July, 1880, when it was nearly low water, one was seen coming down the same river by persons standing on Totnes Bridge, which is twelve miles from the sea, pursued by an otter ; the pilchard leaped on the bank and was secured. They will eat small Crustacea, and their stomachs are found gorged with such food, and also any similar to that eaten by the herring. The roe of the cod or ling they devour voraciously, also crumbs of bread. Off the French coast salted fish roe, mostly of the cod but also of the mackerel, mixed with the pounded flesh of that fish, is employed to attract pilchards. It is termed resure, rave, or more commonly rogue, and is largely brought from Norway, more especially from Dronthein. The fishermen say that they have seen pilchards in multitudes quiescent at the bottom of the sea, as if examining with their mouths the sand and small stones in the shallow water, and probably hunting for food. During the colder months of the year they are frequently found in the stomachs of large ground fish that have * In "Natural History of Ireland" (1755, p. 192) exists an extract from a letter by the Archbishop of Dublin, wherein he observes, "there was a good fishery of pilchards on the south coast of Ireland before the year 1688, but since the fight in Bantry Bay between some of the English fleet under Sir George Rook and the French in 1689, the pilchards, I understand, have not been on that coast : the reason of their leaving it is supposed to be the shock given by the firing of guns ; and it was observed that some gentlemen having provided a yacht for their pleasure and firing' their guns frequently in the Bay of Dublin, the herring fishing in the Bay failed entirely that season." Couch observes that the firing of a heavy gun at the distance of twenty miles has been known to cause the fish to sink, and thus disappoint the hopes of the fishermen. 15 226 PHYS0ST0M1. been taken with ground lines some distance from the shore : the largest fish, similar to the mackerel, being furthest out to sea. Mr. Dunn found that at Mevagissey pilchards of late years have averaged, from August 1st to November 1st, from 3300 to 3800 per hogshead. Migrations. These fish are found off the coasts of Cornwall and Devonshire throughout the year. In January they keep near the bottom, and are frequently taken from the stomachs of line-caught fish. Considerable assemblages, mostly of spent fish , have been observedjin February, becoming more abundant in March; but the chief fishery commences with drift-nets in July and with seines in the succeeding month. During the summer they may be met with from 20 to 50 miles from the coast, as outside the Scilly Isles, and a considerable distance up St. George's Channel. In or about August large schools of smaller fish extend from the Lizard so far as Bolt Head, in Devonshire, further to the eastwards of which no very extensive fishery is carried on, although considerable numbers are taken at Torbay, Teignmouth, and Dawlish. Another large fishery in fact a continuation of that already referred to stretches from the Lizard to the Land's End, while a third is present on the north coast of Cornwall, having its chief seat at St. Ives, where the fishermen assert the large pilchards arrive in October and November, about three days subsequent to their appearance at Kinsale, in Ireland. Sometimes one of these districts is full of fish, none being present in either of the others. Irrespective of these larger migrations there are lesser ones, influenced by currents, tides, and searchings for food ; they appear rarely to go directly against a current. Parnell (Fish. Firth of Forth, 1838) remarks that the pilchard has become of late a very rare fish in the Firth of Forth, as well as along the whole eastern line of the Scottish shores ; yet, about thirty years ago, it was found in equal abundance in certain localities as the common herring. A few are taken occasionally in the summer months on the Berwick and Dunbar coasts, but since the year 1816 no appearance of a pilchard has been observed in the Firth of Forth. We are likewise informed that pilchards were more than usually abundant at Yarmouth in 1780, 1790, and 1799. From inquiries he had made, Couch tells us that some considerable changes have taken place in the times at which the larger bodies of these fish have arrived. Thus, for upwards of thirty years, at the middle of the last century, the most successful portion of the pilchard fishery was carried on after the autumnal equinox, and consequently by drift nets, since the seines could scarcely have been exposed to the risks inevitable from stormy weather and long dark nights. Towards the end of the century the principal fishing was from the beginning of August to the end of September, and at that time a great increase took place in the number of seines. Now (1868) the winter fishery along the southward coast is the chiefly successful one, with the necessary result of a diminution in the number of seine nets, there not being a foui*th part in use that there were fifty years ago. Many of the fishermen assert that the number of pilchards now captured in Cornwall is much less than used to be the case. They point out numerous small landing-stages, all of which during the last or present century, were used for disembarking the fishermen's spoils, but have now fallen into ruin or crumbled to decay, owing to there being no longer any need for their services. It has been said that the pilchards in some seasons swim low, due to diminished temperature in the upper waters, or from some other cause, and consequently escape beneath the nets. The amount taken of the summer fish is not an invariable index to the quantity present, but more depending upon the course they select ; for if they keep in deep water they avoid the seines, and should they swim low they escape the drift nets. Mr. Dunn observes that during May and June these fish appear to be in the deep waters of the English Channel ; that at this period the mackerel nets used off Penzance have a large mesh for the purpose of taking the large mackerel, and through this pilchards can easily pass. Whereas at Mevagissey the nets used are for the lesser-sized mackerel, for which purpose a smaller mesh is necessarily employed, in this the pilchards mesh or entangle themselves when full of roe, being unable to pass through. The fishei*men returning from the east clupeim:. 227 coast towards Cornwall in the autumn, often pass quantities of pilchards in the English Channel, especially off and beyond Portland. Couch observed that for several years, in the early part of this century, the larger proportion of the shoals consisted of such small fish that they passed through the meshes of the seines. Mr. Wilcocks also met with similar sardine-sized pilchards in Guernsey. Means of capture. This is carried on by means of drift or driving nets which can be employed over any depth of water, and in which the fish are meshed or gilled. Bright nights are not so favourable for pilchard fishing as cloudy ones, but in very dark nights the brimming is so bright that the nets look like a wall of fire and deter the fish. In coast fishing they are shot as already observed (page 225) and after sunset, between the shoals of pilchards and the deeper water into which they retire at daylight after feeding. Seines or circle nets are also used near the shore, the mesh of these latter being smaller, as f of an inch between knot and knot, which is of this size in order to prevent their being able to mesh themselves, for if a shoal were encircled and they contained gilled fish, they would soon die, and such a weight of pilchards would be too heavy for the net and cause it to sink. Seine nets are shot between sunrise and sunset, the smallest legal ones at St. Ives being 160 fathoms along the cork rope with a depth of 8 fathoms at the centre or bunt, and 6 at the end of the wings. Some are as long as 200 fathoms, the mesh being f of an inch between knot and knot, or 18 to 20 rows to a foot. 18 feet of netting are attached to each 11 feet of back rope and the same amount on each ten feet of foot rope. A line of corks goes along the upper edge, and the foot line is weighted with leads. The following regulation exists in the Sea Fisheries Act, 1868, 31 and 32 Vict, cap. 45, sect. 68 : " On the coast of Cornwall, except so much of the north coast as lies east of Trevose Head, no person between the 25th of July and the 25th of November in any year " ' (a) Shall, from sunrise to sunset, within the distance of two miles from the coast, measured from low water-mark (whether in bays or not) use a drift net or trawl net ; or (6) shall, within half a mile of any sea fishing-boat stationed for seine fishing, anchor any sea-fishing or other boat (not being a boat engaged in seine-fishing), or lay, set, or use any net, boulter, or implement of sea-fishing (except for the purpose of seine-fishing).' " Any person who acts in contravention of this section shall be liable, on summary conviction, to a penalty not exceeding twenty pounds." As there are only six stations (locally termed stems at St. Ives) where seining can be carried on, and nearly 250 registered nets, they are arranged in groups, each of which is worked so many times in accordance with its size. In this mode of fishing, observes Couch, a whole shoal may be enclosed, and when the evening has set in, and at low tide, the fish are removed. This is done by a small boat passing inside the enclosure and laying its net or tuck seine round the inner side of the large or stop seine so as to gradually contract the limits within which the fish are and raise them towards the surface. When disturbed they dash violently about, and care is necessary that they do not break out, while, to prevent them passing from the tuck net into the stop seine, stones suspended from ropes, termed minnies, are constantly kept plunging towards the only aperture. The tuck net is raised so that the fish are brought to the surface, from which they are removed into the boats with baskets by the fishermen, who are in pairs on the gunwales of the boats (Couch). There is no necessity to remove the whole of the fish that day, in fact a net containing these fish has been kept a week, and a portion of its contents removed as required every night. At St. Ives one end of the seine warp is left on shore and the net rowed round the shoal. Huers, also termed Balkers, are employed for the purpose of keeping a look-out from the cliffs along the shore for the schools of pilchards, similarly, as already described, for observing the mackerel. They receive each about 3 a month and one-hundredth part in kind of the fish taken by their respective companies. Fish being seen the cry is raised " Hev-ah, hev-ah." And, about 1604, it was enacted 15 * 228 PHYSOSTOMI. that no action for trespass would lie against these people for going on any lands when in pursuit of their calling. It was also permitted to fishermen to haul their nets on the nearest shore. The fishery carried on during the last six months'of the year is the most important, because pilchards are then in a condition in which they will cure or " save " best, being fat and with undeveloped roes. Of late years large quantities have been taken during the first six months of the year, they are purchased by local dealers, and forwarded by rail to provincial and Welsh markets under the term of " white herrings." Mr. Dunn observes that off Mevagissey he has known three pilchards having been captured by hook and line, the bait being a small bit cut out of the side of another pilchard. Couch had been informed of two or three instances in which this fish has been known to swallow the fisherman's hook baited with a worm. Rutty, in 1772, observed that their best bait is the spawn of a cod, stock-fish, or mackerel, which is salted and kept in barrels for this purpose. Breeding. Off the coast of Cornwall Mr. Dunn observed that it appears to breed at two seasons of the year, May and June, also in December, and the young are first seen in September, 3 or 4 inches in length and about one-eighth of an ounce in weight. On January 16th, 1882, these fish were returning to the bays shotten, and one boat took 6000. Couch placed the winter breeding as commencing as early as October, but this, of course, would vary with the temperature of the season. I opened large numbers in the month of August, but in only one single instance did I find developed roe. The pilchard deposits aboiit 60,000 eggs, and falls off in condition as spawning time is approached, when it becomes dry and tasteless. Off Mevagissey it has seldom been observed to spawn within 10 miles of land, usually from 20 to 30 miles off shore : the first named of these localities is generally chosen in the summer, the latter in the winter or spring, " and off the coasts of Devon and Dorset instead of Cornwall" (Dunn). Mr. Cornish (Zool. 1883, p. 431) gives his reasons for supposing these fish to spawn in the mackerel season, i.e. between February and June, in the deep sea, eight or more leagues S.W. and round to the W. of the Scilly Isles. Couch observed that the males exceed the females in number, and he believed that they did not attain their full growth until their second or third year. Mr. Dunn recorded that he has seen the roe pressed from the fish when alive into a bucket of water, and each egg rests just below the surface : also that the spawn, on first being shed, actually floats like cork on the water. He likewise informed me, Sept. 29th, 1883, that large shoals of young fish from 2 to 4 inches in length, and believed to be young pilchards, were then in Mevagissey Bay and mackerel were preying on them. Hybrids. Dr. Giinther, Proc. Zool. Soc. 1868, p. 377, describes what he believes to be the hybrid between the pilchard and a shad. Pilchard fisheries. To a stranger visiting the fishing-quay at Mevagissey an hour or so after midnight, when the pilchards are being landed and sold by their captors, the scene is by no means devoid of interest. The Jowters, with their light traps and fast-trotting hacks, are assembled ready to purchase the fish they require, and scour the country in order to retail them to the inhabitants of every village and hamlet. The pilchards, having been washed, are packed in layers, between each of which salt is sprinkled ; this assists in retarding decom- position in these fish, which are so prone to become putrid. At the Barbican at Plymouth, much the same scene may be witnessed, but pilchards are not to be had in sufficient quantities, and cartloads of the coarser description of fish are circulated by means of these Jowters : 12,000 to 15,000 hogsheads of pilchards are annually exported from Cornwall, and the autumn fish, being more firm and less oily, are generally prepared for the Italian market. A merchantable pilchard must be 8 inches long, well-coated, washed, cured and pressed. A hogs- head contains from 2900 to 4000 summer, and 2300 to 2900 winter fish ; it measures 54 gallons, and should weigh, when filled and pressed, 476 lb. gross. Its length is 33 inches, diameter of bilge (stave included) 24 inches, of head (stave included) 22| inches, of head within 22 inches (Fox). A large trade in pickled pilchards is carried on between Cornwall and the Italian ports, the idea having originated at Mevagissey as follows : In 1876, observed Mr. CLUPE1ML 229 Dunn (Land and Water, Nov. 18th, 1882), a fish-curer here found there was a demand in the Mediterranean fish markets for bright salted pilchards. He first thought the matter out and then cured several tons of pilchards by throwing them, with salt, into barrels and allowing the brine to rise over them. After keeping them steeped for some weeks they were washed, packed, and pressed into clean barrels just as was formerly done to the old-fashioned fumadoes. On their being put on the market it was at once seen they were the article wanted, for these fish, instead of having the dirty yellow hue of the fumade, had the desired bright and clean silvery colour, hence they have been in demand ever since. The fish-curer in question took out no patent rights, but allowed all to use his discovery, so much so that for some seasons past not less than 1000 hogsheads of fish yearly have been shipped for the Mediterranean from Mevagissey alone. The barrels first used have been superseded by large steeping vats, one of which here will hold over 500,000 fish. Since the business in question has been progressing, it has been discovered that the Spaniards cure sardines niuch after the same manner. Fumadoes * are thus prepared, a layer of salt is first placed on the floor, then a layer of fish, and so on up to from 3 to 5 feet high the outermost row of fish having their heads out and slightly turned up, and the inner rows at right angles to them. French or Spanish salt, being of a coarser grain than English, is preferred. The bulk remains thus about a month, and the oil as well as the brine which drains from them is collected into a receiver. They are now cleaned, the dry salt is removed by a seive, they are subsequently washed, and packed in regular order in fifty gallon casks, the fishes' tails being directed to the centre. Pressure is now made by means of levers to which weights are hung, the casks being refilled and pressed three times during nine days. A hogshead should weigh 476 lb., while the number of fish in each cask varies from 2500 to 3000. All fish under 8 inches in length are excluded (Fox). Sardines are prepared at Mevagissey as follows : Immediately the fish are landed they are taken to the factory and cleaned, then the washer arranges them in light trays, head downwards, to drain and dry. They are next boiled, then packed in tin boxes, which are filled up with the best olive oil and subsequently soldered down. These tins are again boiled, and the fish are ready for the market. An experiment made to smoke them like herrings failed, as the weight of the body caused the fish to give way and fall into the fire. The pilchard fishery in Ireland in the 17th century brought in from the French and Hollanders in some years 15,000 or even 20,000 as observed by the Earl of Cork in 1631. Smith in his History of Cork, 1750, refers to the pilchards having left Ban try, due to which the town had fallen into decay. " The fishery began about St. James's day, or the first dark day in July : for the first three months the fish were large, fat and full of oil, and were saved with difficulty, beinsr darker and worse coloured than those taken in the winter months and less prized in foreign markets ; notwithstanding which they afforded more profit having a much greater quantity of oil than those taken in the fishery held to the end of the year." As food. These fish are much esteemed in Cornwall eaten fresh. Halliwell mentions a Cornwall dish as starry-gazy-pie, being one made of pilchards and leeks, the heads of the fish appearing through the crust as if they were studying the stars. The chief market for cured pilchards is Italy, where there is a great demand both before and during Lent. Uses. As bait pilchards are found to be more attractive than herrings, probably due to the large amount of oil which exudes from them. Pilchard oil possesses a more greasy nature than that of other fishes, so is considered excellent for coarse painting, and used to be in vogue for lamps in Cornwall. It is also employed by curriers in preparing leather. This oil was one of the chief items calculated upon towards defraying cui-ing charges, and although its value has * The name indicates that these fish were formerly smoked. Boilase, in 1758, observed " fuming them being for many years laid aside." 230 PHYSOSTOMI. become reduced during the last twenty years it has not fallen below 20 a ton. Mr. Dunn remarks at Mevagissey that in seasons of plenty 3 gallons of oil are obtainable from every hogshead of pilchards,* whereas in bad seasons, the fish being few, merely about 1 gallon can be extracted from the same quantity. In this computation only the summer shoals are alluded to, as the yield in winter is hardly more than half what it is in the summer. In a MS. note in my copy of Pennant's Zoology, 1776, I found it stated, " If the fish are very fat 8 hogsheads of pilchards will produce one hogshead of oil." Rutty, 1772, observed in the county of Dublin that the oil serves curriers and for lamps : while the fish are preserved in casks of beech wood. Diseases and causes of destruction. The picked dog-fish, Acanthias vulgaris, is partial to these fish, pursuing the shoals and even tearing them out of the fisher- men's nets. Mr. Dunn, writing from Mevagissey (December 4th, 1882), observed how these predatory vermin in many instances rushed in numbers at the netted fish, eating all the captives and doing so much mischief that some boats had their nets entirely destroyed. Others left the ground, which is within a few miles of the Eddystone rocks, while at one time it was thought probable that the fishery would have to be entirely given up. Other forms of predatory fishes, porpoises, whales, and birds likewise prey extensively upon them. It is not unusual to see these fish removed from the nets with one or both eyes gone not, I think, due to the gar-fish, Belone, or the saury Sco7nbresox, having pierced their heads but consequent upon attacks of fish parasites. In several instances in which both eyes were gone I found the bony interorbital septum still intact which it could not be had the fish been pierced through the two eyes. It is found with Lernece perforating its eye as seen in sprats. Habitat. It is found from the seas of Northern Europe extending to Madeira, also off the French and Spanish coasts, and the variety sardine is found through the Mediterranean. At Aberdeen an example was taken among some herrings in November, 1881 (Sim) : Firth of Forth (Parnell) : Berwickshire (Johnstone). A casual visitor off Yorkshire, occasionally in some numbers (Yorkshire Vertebrata), and every year off Yarmouth (Yarrell), Harwich (Dale), also a few have been taken off Dover, in the Downs, and in the Isle of Wight by herring fishers. In May, 1838, Yarrell obtained one from the Thames. Under the head of migrations I have alluded to their distribution along the south and south-west coasts of England, as it is more especially a Devonshire and Cornish fish. A few occur in Swansea Bay, but I believe never in shoals (Dillwyn). In Ireland it is local and chiefly taken along the south coast, where a few occur every year, while occasionally large numbers are captured, especially near Cork. It has been recorded from Belfast Bay, Newcastle (County Down), Youghal, and the south-west of the counties of Cork and Galway. Andrew (Ich. S.W. Coast of Ireland, P. Roy. Dub. Soc. v, 1866-70, p. 382) observes that small fry of the herring and pilchard are met with in the month of October in great quantities in Dingle and in Ventry Harbours and the Short Strand. The pilchard rarely exceeds 11 inches in length ; but Mr. Cornish (Zool. 1879, p. 62) observed that on December 29th, 1878, he measured the largest he had ever seen, and thnt it was Uf inches long, while Mr. Dunn has seen one of the length of 14 inches, taken in a mackerel net. * Couch observes (iv, p. 92) that when these fish are in bulk 8 or 9 gallons of oil have been obtained from a hogshead.

Colours bluish along the back, becoming silvery on the sides and beneath, in the young a yellow or bronze band divides the blue of the back from the silvery abdomen, this band being frequently more intensely golden during the breeding season. Varieties. Moreau divides C. phalerita, Risso, from this species, as he considers the subopercle in the first is twice as long as high and in the sprat three times. * Neill (Mem. Wern. Soc. p. 545) observed that if a straight line be dropped from the forepart of the dorsal fin it will in the herring fall a little in front of the ventral fins, but in tlie sprat it will fall just behind ihem. 232 PHYSOSTOMI. Fleming, following Willugbby and Ray, observed that the fry of the herring and pilchard are confounded together nnder the epithet sprat, consequently he ignored this species, although Pennant had previously contested this view. The sprat and the sardine were considered synonymous by Lacepede and others. Names. Garvie, garvocJc, or garvie-herring, Scotland. Sprat, besides being the name of this fish, is in places erroneously employed for the young of the herring. At Teignmouth, in Devonshire, this tish is termed the London sprat, as the sand-eel, Ammodytes, goes by the designation of "sprat." Britt along the Devonshire coast, and which ascends the months of rivers, consists either of young sprats or young herrings. Whitebait likewise may be wholly or partially composed of small sprats. In Ireland the fishermen at Youghal distinguish several varieties as true, soft, or hard-headed sprats. Coog Bennog, Welsh. De Sprot, Dutch. L'Esprot, French. Habits. Gregarious ; often in enormous shoals, while it is very common to find young and old together, although the larger examples do not generally come off our coasts until the autumn and winter months. They ascend rivers as high as the tide flows. Britt, which consists of young herrings or young sprats, ascend rivers along the Devonshire coast, and are found as high in the Exe as Exeter, unless a flood occurs, when they are unable to face the fresh water. Migrations. Although during the very cold months herrings and pilchards more or less retire to the deep, sprats, on the contrary, come towards the shore ; but even when present the shoals are capricious in their movements, as well as in their extent. Thus, in 1832, it was observed in Taunton that after an absence of nearly fifty years this fish visited the neighbouring coast in exhaustless shoals. Norfolk, Suffolk, Essex and Kent are noted for the large shoals which occasionally show themselves, while they disappear more completely from the western side of the kingdom during their season of absence than they do from the eastern. Even the time of appearance varies considerably in different years at the same place. During the stimmer and autumn months young or small in-shore sprats are rarely absent from our coasts. In the Moray Firth, and elsewhere, shoals are frequently discovered by seeing flocks of gulls and other sea-birds hovering above them. Means of capture. These fish are mostly captured during the winter months, whether in Scotland or in England. In 1880 this fishery commenced in the Beauly Firth on October 12th, but on the south-west of Ireland it is earlier, and in Donegal Bay continues from August until nearly the end of December. When fished for in the sea they are generally taken from close in shore to about three miles out. Sprats are mostly captured by means of a large bag-net, made with small meshes, and termed a stow-net, the use of which was formerly forbidden between November 10th and February 10th, but which is now the principal time it is carried on ; while ground seines were legal between November 1st and April 1st. The stow-net is placed in a tideway, its mouth towards the tide. In Scotland the seine net is used for taking these fishes, while off Ramsgate drift nets are also employed for sprat fishing, dark and foggy nights especially being suited for its capture. In Ireland the sprat fishing is carried on during the autumn months, and Mr. Sinclair, writing from Donegal (Field, November 5th, 1881), observes that the sprat fishing is now over. One method adverted to by Mr. Yescombe, in Land and Water (November 26th, 1881), is to choose the vicinity of an old wooden pier, or some such structure, round the supports of which small shoals of sprats frequent. Secure your boat to the end of one of these piles on a fine day ; use a net attached to a thin iron frame about 3 yards in circumference, and which is suspended by three cords fixed to it at about 3 feet apart. About a foot above the ring of the net these cords are tied together and attached to a single strong one. The net is lowered into the water to about 2 feet below the surface, and some fine-boiled mealy potatoes thrown in, which attracts the sprats above it. Then allow it to be quietly drawn up with the fish that are swimming above it, and the shoal does not become alarmed. Said not to be taken by a bait, probably from the small size of its mouth. Breeding. I have obtained sprats with developed roe from both the north and south coasts of Cornwall, during the months of December and January, but CLUPEID^E. 233 it is not common to find them in this condition. Neither Pennant, Turton, Jenyns, or White, advert to the breeding of these fish, but Yarrell states he caught some off the Dorsetshire coast in June which were then in roe, also young sprats off Ramsgate, Hastings, and Weymouth, in the months of August and September. Lowe (Fauna of Norfolk, 1873, p. 29) remarks, " Mr. Dowell says, that though he has seen vast quantities of this fish caught, he never yet saw one with roe." Couch observes that in May, 1860, he obtained one 5 inches long and heavy in roe taken 30 miles off shore. Parnell remarked that in the Firth of Forth the sprats spawned early in the month of March. In October, 1879, I examined a number fi-om St. Ives; a few males had some milt, but the ovisacs of the females were empty and red as if spawning were over. Diseases. Mr. Warren (in Thompson's Ireland) observes that "about Christmas, 1846, vast numbers of sprats died in Cork Harbour, and were carried off in bucketsful dying and dead. The people ate them, and considered them very good : it was the year of the famine. They had mostly a ' pearl ' or white appearance in the eye while living : some had both eyes, and others only one of them, diseased." One form of parasitic Entomostraca, Lerneonema rnonilaris or sprat Lernea, is often found attached to the eye of this fish. The whole head of this parasite is inserted into the tissues of its host, and retained there by the barbs or horny prolongations with which it is furnished. This Lernea is luminous at night-time, and fishermen assert that shoals of sprats are often preceded by several of these fishes infested by parasites and which have occasioned their being termed "lanthorn sprats." The britt in Devonshire and Cornwall have been considered by some to be the young of the " herring," but those which I received from Plymouth were sprats. The Town Council of Exeter annually make an official whitebait repast upon " britt," respecting which discussions have arisen as to whether they are or are not similar to the genuine Thames and Medway species. It appears that in the Exe they ascend with the tide so far as the entrance of the Exeter canal, where they are found from May until September. Mr. Ross (Misc.) recorded in 1838 that he took some of these fish to London to Mr. Yarrell, who decided they were the fry of the shad. Mr. Couch subsequently considered them to be whitebait, but not the young of the herring. Mr. D' Urban, the curator of the Albert Memorial Museum at Exeter, transmitted specimens to me, which were the young of the herring. Continuing my investigations into the britt along the S.W. coast, I arrived on August 23, 1881, at Dawlish. At the beach I was in time to see the seine net hauled on shore, and as the bagged portion came to the surface innumerable little silvery fishes seemed to shoot through the meshes into the sea, but hundreds were landed with the refuse, some of which I secured. This gave me another opportunity of examining the August britt. The fishermen considered they were all young sprats, and such I found them to be, while their size varied from three- quarters of an inch to 2| inches in length. Again in August and September, 1883, at Teigmnouth, the britt up to If inches in length were all sprats. It may be that the britt present at the mouth of the Exe from May until September vary with the season, for when investigating the whitebait question in 1878, among examples from the Thames and Medway, I found the proportions of herrings to sprats to be about as follows : May and June, ten to one ; August, sprats rather more than half ; October, all herrings ; while of the winter white- bait given me by Mr. Charles from the Medway, all were sprats. On August 13, 1881, at St. Ives, innumerable young sprats were being taken as bait for gurnards, although they appeared to be entirely absent from Penzance, which was locally attributed to the bay being too sandy ; and I saw a solitary example at Mevagissey, captured among pilchards. As food. These fish are very deservedly esteemed, especially when not too large. As they are nutritious and cheap, they are a boon to the poorer classes. They are sold by measure. They come into the market just after the herring season is over. 234 PHYSOSTOMI. In Norfolk considerable quantities are prepared and sold as anchovies and anchovy paste (Lowe). In some parts of Scotland they are thus preserved : selected fish are washed in salt and water, then threaded on wire skewers and suspended for two hours in a pickling vat, so that no two fishes touch one another. On being removed they are hung up in a current of air until the next day, when they are smoked like bloaters until they assume a yellow colour. They will keep four or five days, and additional pickling and smoking will enable them to keep longer. An important trade appears to be springing up at Lowestoft, where they are being tinned as anchovies. Three million tins of sprats similarly cured as anchovies on the west coast of France are annually imported into this country. Those taken off Finisterre are found to possess a muddy flavour, but they are expoi'ted by some second-rate mercantile houses. A so-called anchovy paste may be made as follows, sufficient for a peck of sprats : 2 lb. common salt, 3 oz. bay-salt, 1 lb. saltpetre, 2 oz. of prunella, and a few grains of cochineal, pounded well together in a mortar ; into a stone jar place first a layer of fish, then of the pounded ingredients, and so on until the jar is filled ; press them hard down and cover closely. After six months they will be ready for use. Uses. As bait for ground fish, for which purpose their oily nature makes them very acceptable. Large quantities in some years are disposed of for manure, which may be due to the markets being glutted, or else that by the time the fish have been landed, those which were first caught are fit for nothing else. In some localities they are even fished for solely with the view of being employed as manure. It has been observed in Berwickshire that they are largely eaten by the salmon. Habitat. From the Finnish coast, through the North Sea and Baltic, also along the coasts of the British Isles, France, and the Iberian Peninsula. It is also found in Tasmania (Giinther). A large fishery exists in the Zuyder Zee : in 1882 it closed in August and fish valued at 70,000 wei'e secured. In the Moray Firth it is abundant on the east side towards the end of the herring season, subsequently it passes westwards towards the more sheltered parts. Parnell remarks that it is found in the Firth of Forth throughout the year, but like many small animals, it appears to be very susceptible to cold ; while during the warm summer months it may be seen sporting about in large shoals. It is common along the east coast, while some of the largest fisheries are in the Solent, the mouth of the Thames and off Margate. Off Folkestone, in January, 1879, the sea appeared alive with them, and they were sold at l^d a 1000. In the British Channel, or rather on the southern shores of Cornwall, it is rare ; on the northern coast it is more common. Having personally investigated the distribution of this fish along this portion of England in the autumn of the last four seasons, I found the young very common along the south coast of Devonshire ; also sprats are numerous at St. Ives. But at Mevagissey and Penzance it seems to be rare. On the west coast of England it is occasionally abundant, but not to so great an extent as on the east coast (see migrations). In Ireland it has been recorded round the coast, but there is no sprat fishery off the counties of Antrim or Down ; still it is taken in large quantities along the south coast. Templeton observes that it appears during the autumnal months in the bay, and as far up the rivers as the tide flows. Largest specimens personally obtained 5| inches in length, but three are mentioned as sent from Aldborough over 6h inches in length (Field, January 21st, 1882). 4. Clupea alosa, Plate CXL.

On the lower branch of the outer branchial arch of this species they are long, thin and numerous, being from 60 to 80, the number of which Canestrim suggests increases with the age of the fish. Fins dorsal commences nearer to the end of the snout than to the base of the caudal fin. Ventral inserted behind the origin of the dorsal. Scales 15 to 17 strong carinated scales along the abdominal edge posterior to the insertion of the ventral fin. Fine ones extended over the basal two-thirds of the caudal fin : back greenish blue ; sides silvery, dashed with purple and gold. Colours occasionally one, sometimes two, dark shoulder spots, while a succession along the side has been recorded, more especially in the young. This and the next species belong to the genus Alausa, or Alosa of some authors, separated from the true herrings owing to an emargina- tion in the centre of the upper jaw to receive a knob existing above the symphysis in the mandibles. Teeth in the front portion of the jaw only, and very deciduous. Shad are not unfrequently considered giant sprats, herrings or pilchards. Names. This and the next species are known as Bock-herrings in the Moray Frith (Gordon). Allice-shad, alewife, mother of herrings, darning -her ring, or possibly " dame of the herrings," king of the herrings, Scadina. Herlyn or Herling, Welsh. Be Elft, Dutch. Habits. Not generally found in shoals in the sea, but becomes gregarious when entering rivers : one hundred shad are observed to make more commotion at sea than 1000 mackerel. Some authors have observed it in the Severn during April and May, and as high as Worcester. Off Cornwall it appears earlier than the Twait-shad, and is equally common (Couch) ; often plentiful in May and June. But the time of its ascent depends to a great extent upon the condition of the water, as in the Severn, if in flood, it waits until such is over, or even returns to the sea. It is reputed to take pleasure in music, but should it thunder while it is in the course of ascent it immediately retrogades to the ocean. Mcintosh found in the stomach of a large example captured in the Tay 236 PHYSOSTOMI. Conferva?, Desmids, and a quantity of vegetable debris, also many sprats and herrings. In Germany Barfurth remarked that its food mostly consists of Temora velox Lilj. and other marine Entomostraca. Means of capture. In fresh waters mostly netted, especially in seines at night time ; it has also been taken in a trammel, as well as when whiffing at sea for pollack, with a slice from a mackerel or sand eel : and Mr. Dunn has known as many as 600 secured in one haul of a mackerel seine. Breeding. Usually from May until the middle of June, and for which purpose it ascends rivers. Barfurth showed that not only do salmon and trout more or less cease feeding during the breeding season, but that in the Rhine the same phenomenon has been observed in the Maifische or shad. As food. Opinions vary, and for several reasons. Being full of bones it is more troublesome to eat without being choked (unless properly carved) than most persons approve of, but if carved properly this unpleasantness is avoided. Taken from the sea during the winter it is poor and dry, but after sojourning in fresh water it becomes plump and delicate, while the higher it ascends streams the better it is. The supply in our markets mostly comes from Holland ; last April they were selling in London retail fish shops at 6d a lb. Habitat. Said to be absent from Sweden, but found on most of the western coasts of Europe, entering rivers in the spring. Off Banff it is rare, but one was captured there in a salmon net, June 7th, 1866 (Edward) ; at St. Andrews it is not uncommon (Mcintosh), Firth of Forth rare (Parnell), Berwickshire (Johnston). It is found off Yorkshire (Yorkshire Vertebrata), and at Yarmouth is not uncommon with the herrings (Paget). A pair, male and female, were taken at the New Mills in Norwich, in 1840 (Lubbock) ; it is found along our south coast, but becomes rare in Mount's Bay and St. Ives. Said to be abundant in the Severn in some seasons during April and May. Yarrell obtained a specimen in 1831, captured above Putney Bridge on the Thames, and Jesse recorded one taken at the end of June, opposite Hampton Court Palace, full of spawn. In Ireland taken on the north-east coast and is not uncommon off Derry (Ordnance Survey) ; it is by no means rare on the west coast and has been seen in Kenmare river, Ventry harbour, and Dingle Bay ; is often abundant in Limerick harbour and Brandon creek, coast of Kerry ; and has been taken near Killaloe on the Shannon (Mayne). It attains to as much as four feet in length (Couch) and up to 8 lb. in weight, but generally is seen to about half this size. 5. Clupea finta, Plate CXLI.

Eyes with adipose lids, diameter 4 \ to 5-| in the length of the head. Opercle with some raised and radiating lines descending towards the sub-opercle. Upper jaw with a notch in its centre, to receive the end of the somewhat prominent under jaw ; the maxilla reaching to beneath the hind edge of the eye. Teeth small and deciduous in jaws : absent from the palate and the tongue. Gill-rakers thick, osseous and from 20 to 28 along the horizontal branch of the outer branchial arch. Fins dorsal commences nearer to the end of the snout than to the base of the caudal fin. Ventral inserted slightly behind the origin of the dorsal. Anal fin low. Caudal deeply forked.

Colours steel blue along the back, becoming silvery along the sides and below, a large black blotch on the shoulder, generally succeeded by about 5 or 6 more (Donovan says 10) along either side ; in some specimens there are two dark spots at the base of the tail, one above the other below. Varieties. Couch has noticed a scattered row of irregularly placed small spots along the sides, instead of large dark spots in one specimen which he supposed to belong to this species. Names. Twaite in the Severn, shad signifying the last species. Maid. Bony Norsemen, Ireland. V 'Alose feinte, French. Habits. These anadromous fish leave the sea at the end of May or commence- ment of June, and ascends some of our large rivers as the Thames and Severn, for the purpose of depositing their ova ; formerly they went in the Severn far above Shrewsbury, but since about 1846 have been more or less stopped by the Tewkesbury river. All have usually returned to the sea by the end of July. Mr. Miller, who has the fishing at Newnham, in the Severn near Gloucester, says that it commences from the 14th to the 20th of April, according to the heat of the season, for if cold winds blow it is deferred. Small males come first, so small that two only equal one female ; at first the wholesale price is 6s a dozen, later on 4s, as one hen counts for two cocks and thirteen to the dozen. Means of capture. Similar to the other form of shad. Yarrell observes, that in the Thames great numbers were taken every season, especially opposite the Millbank Penitentiary, Westminster, also above Putney Bridge. But the stafe of the water has caused a more or less complete cessation of their visits. Formerly their capture in the Thames was prohibited after June 30th, in order that spawners might breed in security. We are told that in Germany this fish is believed to be terrified at storms and troubled waters, delighting in quiet and musical sounds. Therefore to the nets are fastened bows of wood, to which are suspended a number of small bells which chime in harmony together on the nets being moved : the fish are thought to be thus attracted to their destruction, and as long as the alluring sounds continue they cease all efforts at escape. Baits. Whiffing with a slice of mackerel has been found successful at the mouth of the Dart (Holdsworth). This fish is capricious in taking a bait in the Severn, being occasionally hooked at almost any cast, at another time playing around the bait but refusing to touch it ; when hooked it affords some play. Breeding. June and July. On June 3rd, 1879, 1 opened several from the Severn, the ova was almost ready for being deposited. Yarrell observed, that about the second week in July used to be when they mostly spawned in the Thames when they appeared to disencumber themselves of their roe by violent muscular action, and on a calm still evening or night, the noise thev made miffht be heard at some 238 PHYSOSTOMI. distance. He obtained the young 2\ inches long in October, and only 4 inches long the following spring. Hybrid. Scale-finned shad, Alosa squamapinnata, Couch, iv, p. 123, pi. ccvi, from Bristol, the skin of which is now in the National Collection, may be a hybrid between one of the shads and a pilchard as suggested by Dr. Giinther, but its gill-rakers have been removed. Another example in the same collection is considered a hybrid between the two shads, with 40 gill-rakers, longer than C. finta but shorter than G. alosa. D. 21, A. 25, L. 1. 68, L. tr. 22. As food. Owing to its numerous bones is not held in much reputation in English markets, while its flesh is somewhat dry and tasteless. In Russia it is considered unwholesome. Habits. From Scandinavia throughout the seas and coasts of Europe, the Mediterranean and the Nile ; it enters many rivers to breed, as already remarked upon. It has been reported around the coasts of Scotland, as at Banff where it is rare (Edward) ; appearing in the Firth of Forth at the end of July, and disappearing about August (Parnell). Also round the English and Welsh coasts, as off Cumberland (Heysham), Yorkshire (Yorkshire Vertebrata), Yarmouth not uncommon (Paget) ; the Thames and along the south coast as far as Cornwall, where, observes R. Couch, the " twaite shad" Alosa finta, or " Daming-herring," is found in the west part of Cornwall in rather large numbers towards the latter part of the summer pilchard fishery and early in the autumn mackerel fishery. Frequently taken in mackerel drift-nets off Scilly, moving E. or W.E. In Ireland it is taken chiefly along the south coast where a few occur annually, but occasionally in great numbers. It has been recorded from Belfast Bay ; Newcastle, Co. Down ; Youghal ; south-west of the County of Cork and Galway, Dublin, and is common in northern rivers (Andrews). Likewise Black- water (Ball), and Donegal, where 2 or 3 have been taken (Thompson). It attains to 16 inches (Yarrell), it never exceeds 2 lb. in weight. MUR^ENID^E. 239 Family, VI MUR MmVM, Mutter. Body elongated, cylindrical or band-shaped : the humeral arch not attached to the skull. The branchial openings in the pharynx may be wide or narrow slits. Margin of the upper jaw constituted anteriorly by the premaxillaries* which are more or less coalescent with the vomer and ethmoid, while laterally the sides of the upper jaw are formed by the maxillaries which are furnished with teeth. Vertical fins, when present, confluent or separated by a projecting tail : pectorals present or absent. Ventrals absent. Scales, when present, rudimentary. Vent may be situated close to the base of the pectoral fins, or a long distance posterior to the head. The heart may be just, or far behind the gills. Stomach with a blind sac. No pyloric appendages. Ovaries destitute of oviducts. Cuvier placed the eel- shaped fishes (including the tropical SymbrancMdce) in one Family, Mur.NID3:, while they have likewise been termed Apodal, owing to a deficiency of the ventral fins, which latter phenomenon is perceived in species of various other families, for being the last evolved or most immaterial among the fins, they are most commonly absent. Thus in Ceylon and China the genus Channa among the Ophiocephalidas is distinguished from Ophioceplialus by the absence of the ventrals. The Indian Siluroid genus Ailichthys differs from Ailia due to the same cause. Genus Neochanna differs from Galaxias for a similar reason. In the Cyprinodontidaa, Tellia is a Cyprinodon without ventrals. Apua among the Cobitidina? is closely allied to Acanthophthalmus but has no ventrals, while the chief distinction between the Clupeoids Opisthopterus and Pellona is that the former is without ventrals while the latter has very small ones. Calamoichthys is Polypterus without ventrals. Doubtless in some instances this deficiency of the fin may be an individual monstrosity or a local race, as I have observed (vol. i, p. 245) as regards Gasterosteus pungitius. It may, perhaps, be a sexual character, thus Troschel (Wiegm. Arch. 1871, pp. 276-280) remarked upon having received a female Siluroid of Copidoglanis brevidorsalis destitute of these fins. It may be present in the young as 8trom,ate^cs niger, but be lost with age, and absent from other species of the same genus. Attention has likewise been drawn to the fact " that in numerous groups of fishes which live in mud, forms occur, devoid of, or with only rudimentary ventral fins" (Giinther, Annals and Mag. Natural History, 1867, xx, p. 308). Eels by some authors have been looked upon as, sometimes at least, herma- phrodites. But Syrski, Dareste, and others have observed upon what they deem to be the male organs of the eels. A number of larval fishes have been termed Leptocephali or " Glass eels." Some of these may be forms in which develop- ment has been arrested in an early stage of existencef, the fishes never attaining the perfect state, but such are generally, if not invariably, in Great Britain confined to the salt water. It is an error however to consider them as usually restricted to some distance out in the ocean, as along the coasts of the Bay of Bengal they are innumerable and to be found close in shore. The Family Mur^nid^s; are divisible into two groups : (1) Those in which the branchial openings in the pharynx are wide slits, Mtti-wnidce platychistce, among the genera composing which is Anguilla. (2) Those having the branchial openings in the pharynx as narrow slits, Murcenidos engyschistce, an example of which we possess in the genus Murcena. * Meckel, Peters, and Jacoby consider the lateral portion only of the upper jaw is formed by the maxillaries, the front part being the premaxillary which coalesces with the vomer and ethmoid, but may always be distinguished. f Carus, Brit. Asso. 1860, Gill, 1864. 240 PHYSOSTOMI. Genus I Anguilla. MurcencB, sp. Artedi. Terpolepis, pt., McClelland. Paranguilla, Bleeker. Gill-openings of moderate extent, situated near the base of the pectoral fins. Tipper jaw not projecting beyond the lower. Teeth small and in bands. Dorsal fin commencing at some distance behind the nape : pectorals present. Small scales imbedded in the skin. Geographical distribution. Fishes of this genus appear to be distributed throughout the fresh waters of the habitable globe, being reputed to be absent only from the Arctic regions, and intensely cold districts such as Turkestan, and a few other localities. Species. As may be perceived by the most casual observer, these fishes have been subdivided to such an extent tbat it is difficult to comprehend the plans upon which authors have founded their species. Yarrell divided the British forms into the "sharp-nosed eels," "the broad-nosed eels," and "the snig," observing that in the comparative breadth of the nose (snout) the last is inter- mediate between the other two. Giinther remarked " the form of the snout, the size of the eyes, and the width of the bands of teeth, are evidently subject to much variation," and subsequently continued, " I am more inclined to consider the situation of the origin of the dorsal fin and the development of the lips to indicate a distinct species," and following out this method of division he looks upon A. latirostris as an inhabitant of Europe, the Nile, China, New Zealand, and the West Indies ; and A. vulgaris as resident in Europe to 60 30' N. Lat. but found neither in the Danube nor in the Black or Caspian Seas, Mediterranean region, Northern Asia, or North America, while he considered these two to constitute the sole British species. It has appeared to myself, while examining numerous eels of this genus in Asia, that considerable local and individual variations occur as to the position of the origin of the dorsal fin and the compara- tive proportional size of one part of the body to the remainder, rendering this character by no means symptomatic of species. Habits. Eels are very tenacious of life, are found in nearly all our fresh waters, and during their feeding months are exceedingly voracious. In an account of some domesticated examples of this genus kept in a pond in a walled garden for nine or ten years,* they were observed to remain torpid throughout the winter, and although they occasionally emerged at the bottom of the water from under the large stones which formed their hiding places, they did not feed. About the latter end of April they first began to take worms, but ate sparingly until the warm weather set in, when they became quite insatiable (in some waters they commence feeding certainly as early as March), while if no other food was procurable they devoured one another ; they also consumed fish roe and occa- sionally vegetable substances. About August they become restless, apparently attempting to migrate to the sea, and at the end of that month or during September they retired to their winter quarters. Eels usually make two migra- tions yearly, one in the spring as April or May, when the young, termed Elvers, ascend from the sea and estuaries up rivers. Couch states that " very young eels have been obtained at the ebb of the tide as early as the 2nd of January ; after watching a river with great care they have not been observed passing up the stream until the middle of March, and rarely even then." The second migration is from the fresh waters to the sea and takes place in the autumn, this is performed by adults for the purpose of depositing their spawn, when they select the mixed water at the confluence of the fresh and salt, where the temperature is a few degrees higher than that in the vicinity. On the banks of the Thames the migration of the young eels is termed "Eel-fare," "fare" being a Saxon or Anglo-Saxon term signifying "to go" or to travel," and Yarrell suggests that the term " Elver " is a corruption of eel-fare." Eels do not like a muddy condition of the water, in fact, old ones * Edinburgh New Phil. Journal, 1841, p. 439. u MUR^ENID^. 241 will quit a pool to avoid it. In the cold months of the year they remain imbedded in the mud, into which they descend some 12 to 16 inches. In Somer- setshire their retreats (for they retire in large communities) on the banks of rivers are said to be ascertained by observing that the hoar frost does not lie over the mouths of the holes into which they have retreated as it does elsewhere. Eels, although often killed by frost, still at times are able to endure a low tempe- rature, having even been frozen, buried for several days in the snow, and then gradually thawed to life again ; while it has been asserted that in Russia they are frozen, and thus conveyed long distances, packed in straw, and are thawed on arrival at their destination. Eels have been known to occasionally quit the water and travel over moist places in search of food, as frogs or snails, or to find more suitable localities in which to live, for some waters are very obnoxious to them. They may be tamed and taught to come for their food at certain sounds, while they appear to recognize those who feed them. 1. Anguilla vulgaris, Plate CXLII, fig. 1.

D. A. and C. 480-500, P. 17-18, Vert. 114-116 (fflff). Lower jaw the longer : the length of the head 2 to 2| in the distance from the snout to the origin of the dorsal fin, and from 3| to 3f to the commencement of the anal fin. Body cylindrical as far as the anus, posterior to which it becomes more and more compressed. Lips broad and fleshy, (latirostris,) or narrow, (vulgaris :) the maxilla extends backwards to beneath the middle or hind edge of the eye. Eye rather small, diameter 8 to 12 times in the length of the head : about 1 to 2 from the end of the snout, If apart. Teeth cardiform in the jaws and vomer. Fins the dorsal commences far behind the head as already observed. The anal arises about the length of the head behind the origin of the dorsal fin, and a little in front of the middle of the total length. Scales small ones under the epidermis and imbedded in mucus. Colours variable, generally dull olive along the back, and white or yellow along the abdomen, fins darker than the body, except the first third of the anal. Among the outward signs by which a male eel may be recognized, says O. Hermes, is a very striking metallic or bronze colour. % Varieties. In colour, piebald, yellow, white, silver, green-bellied, or with a longitudinal yellow band along the back. I obtained a yellow one at Cheltenham, February 1st, 1880. Rutty observed white-bellied or silver eels are the best because they live on a sandy and gravelly bottom, whereas those that live in mud are yellow-bellied and of a less grateful taste. Several distinct species of common eel have been reputed to occur in this country (see page 240), but which appear to be differences due to sex or dependant on sterility. The following are the more striking forms : (1) The "grig" or "glut-eel," Anguilla latirostris, a variety of a small size, having a broad head and snout, the dorsal fin commencing further back than in the next variety, the distance between its origin and that of the anal fin being less than the length of the head, while its dorsal fin is lower and its eyes larger than in the sharp-snouted form. It is mostly found in brackish water and in the vicinity of the sea, rarely ascending rivers any distance above the tides. This is the male. (2) The " sharp-snouted eel," A acutirostris, which is the common form that is taken when descending in large numbers to the sea in the autumn for breeding purposes. Its snout is sharp, its dorsal fin higher and its eye ; mailer than is seen in the male. This is the female. (3) There is also a well- * Anguilla Meneri, Giinther, Fishes of the Porcupine Expedition from the North Atlantic, is a small Gadoid, as previously observed by Couch, and the young of a Lycodes (Day, Pruc.

MUR^ENID^E. 243 marked, generally very broad-snouted when large, non-migratory, fierce and voracious form, which is not choice in its food, and the flavour of which is anything but satisfactory. These appear to be sterile females who have taken up their abode in fresh waters, but as some have been observed migrating seawards at the annual breeding season their sterility may only be temporary. It is rather remarkable that so long ago as 1740 Williamson (British Angler) observed " he and she eels may be distinguished by their fins." Names.

The term eel has been thus described, the noble or adel of Italy, corrupted into the aal of Germany and the eel of Great Britain. Habits. Adult eels prefer pure fresh water with a muddy bottom and appear to be avei-se to cold. They burrow out holes or tunnels where they rest during the day or conceal themselves under roots, bushwood, planks, or other suitable places, sallying out for food at night-time. During the summer months they may often be seen basking near the surface and lying on the vegetation growing in the water. When on the feed they move about at the bottom, inserting their snouts under stones, and have been seen to put up a loach and pursue it from place to place as if hunting by scent. In December, 1860, an eel 39 inches long was taken alive in the middle of a stubble field : there was an old pit in the vicinity containing very little water (G. Hoult, Field, Dec. 1860). Especially on the approach of stormy weather, they have been known to migrate over newly ploughed fields or gardens, where they have been reported to consume the peas. During their migrations tbey have not infrequently entered water pipes and so cut off the supply. Their mode of escaping in an aquarium is remarkable : if possible they commence by throwing their tail over the end of the vessel, and that organ being a prehensile one, they subsequently lift themselves over and so escape by their usual tortuous movement (R. Couch, Zool. p. 1829). Queckett likewise remarked that elvers often progress tail foremost. Eels live a long time in confinement : one resided 22 years in an aquarium, dying on August 1st, 1877, of old age (Hardwicke, Science Gossip, 1877, p. 261). Mr. Daniel mentions one which lived upwards of 31 years in a well and was then choked by a frog that was larger than it could swallow. Thompson observes that from February 6th to the 8th, 1841, great quantities of these fish, in a dead state, floated down the river Lagan to the quays at Belfast. Four of them, measuring from one to two feet in length, were placed in water warmed to a high summer temperature, but none exhibited signs of life. During these two days the thermometer was 10 higher than it had been for the three previous days, but there was a gale from the east accompanied by a hard frost : to the human body the cold felt extreme and piercing ; the eels would appear to have been in the mud which was uncovered and of course subject to evaporation. Dr. Kirtland, of Cleveland, states that last winter (1850) as the frost set in, a number of eels in a mill-pond, incommoded by the subsidence of the ice, migrated to other ponds from which he obtained eight or ten bushels half frozen. Having been placed in a cold exposed room they were as stiff and almost as brittle as icicles in the morning. A tub was filled with them and water from a well added, then they were placed in a warm store room for the purpose of thawing. In the course of an hour or two they were resuscitated and as active as if just taken during the summer (Chambers' Edinburgh Journal, Nov. 29th, 16 * 244 PHYSOSTOMI. 1851). H. Frere (Zool. 1846, iv, p. 1216) considers that cold deadens hearing in fish and where some eels were simply lying beneath the surface of the ice some way from the edge which is usually the last to freeze, he found that a hole could he cut in the ice only two or three inches from the fish, which were easily pulled out with a pair of nippers. Where there were reeds projecting through the ice the concussion carried down by any blow startled the fish, but where the ice was uninterrupted they usually lay quite still until extracted. Lubbock considered the common eel in Norfolk not to be so voracious as the snub-nosed variety, and more regular in its migrations. In the winter, numbers of them are sometimes found laid up in the mud by the side of navigable channels, and several stones' weight have been speared within the compass of a few yards. They may almost be said to be omniverous, for several observers have distinctly stated from personal observation, that they occasionally eat vegetable substances. 0. Melsheimer (Rhenish and Westphalia Natural History Society, 1877) remarks that after a series of years of observation he had come to the conclusion that the food of this fish is exclusively animal. They feed on the ova of fish and Crustacea, and are excessively partial to crabs when they are shedding their shells : also to frogs and snails, and are said to prefer their food fresh, usually rejecting it if tainted. Mr. J. Banister (Zoologist 1843, p. 108) mentions a large rat struggling to escape from a hole a little elevated above and near the edge of the water. It dragged after it an eel about of a pound weight, which appeared to have the greatest portion of the rat's tail in its mouth. After dragging it out about six inches it let go. In another instance a rat was found inside an eel. A skinned mouse, or plucked young sparrow are said to be good bait in Lancashire. Mr. Longstaffe, while walking by the side of Thirston Burn, May 27th, 1875, saw an eel which looked peculiar : he shot it. It was on the point of swallowing a large water vole, and had so far succeeded as to leave only the hind limbs and tail sticking out of its mouth. It was 30 inches long. Eels have also been known to devour moor-hens, young waterfowl, snakes, and fish of any description. Mcintosh (St. Andrew's) gives an instance of one swallowing another smaller than itself. The captive one doubled up its tail, thrusting it from inside through the gill-opening of its captor and choked it. Migrations. Eels, as from c 6\ lb. weight to those of smaller size, descend streams and rivers (as the Severn, for instance) during the first rise in October or November, during which period they cease feeding, but the take is more successful when the floods occur late, because then the weeds have disappeared to a considerable extent. Arriving at tidal waters they continue descending with the ebb, but cease " running" when the tide flows. In Norfolk this downward migration commences in July and continues to the end of November, and it has been observed that as soon as the lamperns begin to run the eel stops. After spawning, but few eels return again to the river. In " the Yare and Waveney, the eels come down in large solid balls from one to two feet in diameter, heads inside and tails out ; and these living balls roll down the river and plump into the nets with such force as to carry them away, for which reason the eel-fishers at the mills dread their coming." A gentleman from Ireland infoi-med me that be had personally witnessed during the months of September and October balls of eels similarly rolling seawards. Pennant remarks that in the river Nyne, in Northamptonshire, there is a variety of small eel that is found in clusters at the bottom of the river and is called the Bed-eel, and is sometimes roused up by violent floods. Pliny observed it in October and suggested they did so to ward off the cold. During the early months of the year young eels, which are transparent, having some minute dark spots on the back and sides, so as to appear longitudinally striped, commence ascending rivers in incredible numbers, which migration, or " eel fare," lias been already alluded to (see page 240). Thus " they pass up the Parret with the tides of March, April, and May ; a few (the fishermen tell me) ascend in February, and those by June are about 3 or 4 inches long. They come in a continual shoal, about 18 inches wide, without cessation, for some days, always against i lie st renin, and close to the left bank. The women catch them at night MUR^flNlD^E. 245 by means of a canvas bag, attached to a hoop, at the end of a long stick to which a lantern is fixed. They are thrown into a tub of salt which cleanses them ; they are then boiled, and pressed into cakes, which are cut into slices and fried, making most delicious food. Sometimes they are so abundant that the people about get tired of eating them, and actually feed the pigs with them " (Buckland). "At an early period in the summer it is an interesting* sight (at the Cutts near Ooleraine, on the lower Bann) to mark the thousands of young eels then ascending the stream. Hay ropes are suspended over rocky parts to aid them in overcoming such obstructions. At these places the river is black with the multitudes of young eels, about 3 or 4 inches long, all acting under that mysterious impulse that prompts them to push their course onward to the lake " (Patterson, Zool. for Schools). In migrations elvers appear to be diurnal in their habits, whereas old eels choose the darkest nights after a flood, while in stews they die most in frosty weather should they have no sand or mud to creep into. Thompson remarks that he has been informed that a run of eels at night-time has been completely stopped in its progress by placing three large lamps so that the rays of light fall upon the surface of the water. Similarly at the great eel fisheries of Commachio it is stated that migrations are suspended or interrupted either by a full moon or tires accidentally lighted in the vicinity ; while thunder likewise prevents their " running" when all else is apparently favourable. The direction of the wind is also of importance ; it is favourable when with them or from any point from the south, but if a sudden change occurs they will cease to migrate for the night. Some excellent authorities upon fish and fishing are disposed to believe that all eels do not ascend from the sea, some being raised in fresh waters ; and many curious localities have been recorded where detached waters have contained eels. Thus a correspondent of Land and Water (July 15th, 1882) observes: "Last week I saw eel and carp fishing going on in the Co. Wexford marl holes. Many of these holes are at great distances from the streams and river, and have no connection with them, so that the eels must go over the land to get to them, and I learn from the people in the neighbourhood that some of the largest eels they get are caught in the grass in summer after rain." Mr. Cornish, among several cases he records, tells us " that at the famous Botallack Mine in St. Just, in Penwith, eels occur in a pond fed by chance supply, situated on the top of a hill close to the blacksmith's shop. And I placed on record some years ago the capture of a large eel in a freshwater pool fed not from the surface, but from the bowels of the earth in one of the old deep levels (or workings) of Wheal Mary Mine, near this place" (Land and Water, June 10th, 1882). Mr. Berry (Mag. Nat. Hist. 1834, vii, p. 301) says he has taken eels of all sizes, from that of a needle upwards, in ponds totally unconnected with and distinct from either river or brook. It has been supposed that as eels as large as 11 lb. or more are captured migrating seaward they must have bred in fresh water ; but this does not follow they may be sterile temporai'ily or permanently, as the one kept over 22 years in an aquarium. Young eels have, as already observed, been known to ascend the flood-gates of lochs, to creep up water-pipes in short, mechanical difficulties scarcely obstruct them ; they will even quit the water and travel over herbage. Lakes which formerly were well stocked with eels have become destitute of them, due to impassable barriers having been erected between them and the sea, preventing migrations to and fro. Means of capture. Eels are in places taken in the largest numbers after heavy storms and floods. These may be in the form of " eel-bucks," as used in the Thames, which consists of a number of wicker baskets or " weals," externally somewhat in the form of a sugar-loaf, and internally like a mouse-trap ; several of them are sxrpported with a wooden framework, the whole crossing the stream. The open side of these baskets is turned up stream, as it is when these fishes are descending that they are trapped. These wicker-work baskets have to be soaked some weeks before being used, or eels will not enter them. At some mills one of the water-gates is left open and a hoop-net fitted to a frame inserted, 24G PHYSOSTOMI. which is often successful in obtaining good catches of descending fish. Thompson says at Toome " they are taken in nets which may be compared to sugar-loaves, with the tops cut off, each from 14 to 16 yards long, and placed between weirs." A blow on the tail is said to quiet an eel. In appropriate localities swigs are stated to be sometimes taken when the openings of the eel-buck are down stream. In the rivers and broads of East Anglia " eel-sets " are employed : these are wall-nets of small meshes set across the stream, the foot rope being weighted and resting on the bottom, while wooden floats are used along its upper edge, and these are fixed to three stakes, one being near each bank and the third in the centre of the stream. They are used for the silver eel, and arrest them during their autumn migration seawards, and in this way tons are occasionally captured in Norfolk. The opinion prevails that it will not readily take a bait or be speared. Baits. Trimmers baited with roach or other silvery fish ; the bait being near the bottom, also night lines. Atkinson (Zoologist, 1844, p. 528) remarks upon never having caught very large eels in the spring or early summer, or on moon- light nights, except the water was foul. They often remove the bait without being hooked, while gudgeons are preferred to minnows. In one piece of water he could not induce them to take Prussian carp. In some of the shallower Norfolk broads, according to Lubbock, the fisherman has a bundle of osier wands in his boat, each about 7 feet in length and sharpened at the thicker end ; about a yard of stronsr strinsr is attached to each. Hooks baited with small fish are beside him, and as he floats along he attaches it to one of his lines and sticks his osier twig down wherever he perceives an opening among the weeds at the bottom. The advantage is that no struggles of eels entangle his line, each being inde- pendent of the other. In Norfolk dabbing or bobbing is thus carried on : a number of lob worms are threaded by means of a needle on worsted, until a bunch is formed. A weight is attached and the bait lowered to the bottom. The babber sits in his boat all night with a short rod in each hand, and every now and then lifts the bab a little. If a bite, he lifts it gently into the boat, the eel's teeth having become entangled in the worsted. The great time for this is when roach and bream are ronding or spawning in the spring, then the eels follow them; it is useless babbing anywhere except in the spawning beds. You can hear the eels sucking away at the spawn in the weeds, and they gorge themselves to such an extent that they will lie motionless on their backs in the gravel. There are two kinds of eel-spears employed in the Broads' district, the prick is con- structed of four broad serrated blades or tines spread out like a fan, and the eel becomes wedged between them. The dart is made of a cross piece with barbed spikes set in it like the teeth of a rake. The spearer watches for bubbles, which denote the presence of an eel, and then uses his spear. In some places the eel-spear is known as "eelshear" or " elger." Broggmg or sniggling is thus performed : when the water is low, and on a hot summer's day, a small hook baited with a red- or dew- worm is affixed to a long line, one end of which is held in the hand. Then the upper end of the hook is loosely inserted into the cleft of a long hazel-wand. Holes or appropriate places for eels are searched for and the bait quietly placed therein. The eels must have time to gorge the bait and be very leisurely extracted from their retreat, for lying doubled up in the hole, they will, if much force is exerted, break the line. Powdered beef, a frog, minnow, intestines of fowl or fish, particularly the offal of mackerel, herrings, or pilchards, while a pride, Petromyzon branchiaJis, exceeds every other bait for night lines. Breeding. From the time of the Greeks this has been a difficulty to naturalists. Thus, Aristotle thought they sprang from mud. Pliny had an idea that fragments of the skin of the parents rubbed off against the rocks developed into young ones, while Helmont gives the following curious recipe : " Cut up two turfs covered with May dew, and lay one upon the other, the grassy sides inwards, and then expose them to the heat of the sun ; in a few hours there will spring up an infinite quantity of eels." Horsehair from the tail of a stallion was asserted to be a never-failing source of young eels. MUR^ENID^E. 247 Parasitic worms, Ascaris, have been constantly pointed at in the intestines of these fish as the developing young ; while other fishes have likewise been the reputed parents of eels. Jacoby tells us that this last opinion is even very prevalent at the present day among eel fishermen, especially such as reside near the mouths of rivers. A slimy fish, Zoarces viviparus (see vol. i, p. 211), owes the name by which it is generally known in Commachio the " eel-mother " to this opinion. It is a very old opinion, prevalent to this day, that eels copulate with water-snakes, but it seems incredible, and is nevertheless a positive fact, that the Sardinian fishermen consider a beetle, Dytiscus Boeselii, as the procreator of the eel. In the seventeenth century Redi and Paullini both expressed their opinions that eels must have both semen and ova; while Mondini, at Bologna, in 1777, read an accurate description, accompanied by excellent illustrations of the ovaries of the eel discovered by himself, and which was published in 1 783. 0. F. Midler almost simultaneously (1780) published a description of the ovaries of this fish, which appear in the shape of a frill-shaped band, extending in the abdomen anteriorly to the forepart of the liver and posteriorly to the vent,* while in this band are numerous eggs, but no duct, as the ova falls into the abdominal -cavity. Rathke, in 1850, described the first gravid female eel which up to that period had come into the hands of a competeut investigator. For some time it was contended that this fish was an hermaphrodite, and it was not until 1873 that Syrski, at Trieste, obtained an eel 15 inches long possessing an undescribed organ as well as being deficient in an ovary. This lobe-organ consists of tubes in areolar tissues, contains a seminal duct, shows no trace of frill-like folds, but appears as a light band with a free edge. Care has to be taken not to mistake two fatty bands, which are always present in either sex of eels, for the lobe-organ. The largest male seen by Syrski has been from 17 to 19 inches in length. Since they were first detected numerous male examples have been found. Gunther, in his "Introduction to the Study of Fishes" (1880), disposes of the investigations made up to that period, remarking: " Their mode of propa- gation is still unknown. So much only is certain, that they do not spawn in fresh water, that many full-grown individuals, but not all, descend rivers during the winter months, and that some of them spawn in brackish water, or in deep water in the sea." The common opinion seems to be that the eel only spawns once in its lifetime, a peculiarity it shares with the lamprey, and this pi'ocess takes place in the sea. The proportion of male to female fish rapidly decreases with the distance from the sea. When the young are hatched they ascend the rivers to reach the inland streams and ponds, where they grow in size but never increase in numbers. It would seem, considering the state of the ovaries so long as these fish continue in rivers, that salt water is needed to develop the pro creative powers. Life history. It has been disputed whether young eels grow rapidly or slowly. f M. Coste says that placed in reservoirs with plenty of food, in four or five years they weigh from 4 to 6 lb. I received alive through the post a little elver, 2T inches long, on May 15th, 1879, at Cheltenham. It did well when placed in an aquarium, usually lying on the top of the Valisneria in the water, and darting away and hiding its head under a stone if frightened : occasionally it ascended to the surface and discharged a bubble of air. By May 27th it had grown to 3| inches in length, during this period having been kept in a tumbler with about two inches of tank water changed daily. It was now taken to Weston- super-Mare, but did not thrive, the water apparently being unsuited. At the end of June it was brought back to Cheltenham, but during my absence died, due to rain water only having been supplied. Fisheries. There are many celebrated ones distributed over Europe, more especially that of Commachio, near Venice : those of the Seine in France, Nar- * The genital opening is a simple orifice which communicates with both halves of the abdominal cavity by means of a transverse fissure between the rectum and the urinary bladder, and opens into the urethra. f Cultivation of Eels, Souberain, A.

In this country the Kennet has long been celebrated for its eels as well as the Isle of Eels, now termed Ely, and other localities, as Cambridgeshire and the Eastern broads. The largest supply is obtained from Holland, and Mr. Mayhew (London Labour and London Poor, i, p. 66) has given a good description of the Dutch eel- boats in the Thames. For in the time of Queen Elizabeth a free mooring was given for Dutch sennits in this river when bringing over eels, a privilege that is still made use of. The holds are fitted up with long tanks of muddy water, and the heads of the eels may be seen breathing on the surface, a thick brown bubble rising slowly and floating to the sides. At the stern of one boat was moored a coffin- shaped barge pierced with holes, and hanging in the water were baskets, shaped like olive-jars, to keep the stock of fish both alive and fresh. In the centre of the boat stood the scales, a tall, heavy apparatus, one side fitted up with the conical net-bag to hold the eels, and the other with the weights, and pieces of stone to make up for the extra draught of the water hanging about the fish. The Scotch will scarcely eat them or even capture them for sale. " Mr. Grurney informs me that he used to find the sharp-nosed eel at Lowestoft along the coast, sometimes nearly a mile from the harbour's mouth very healthy but never large; 2 lb. would be the maximum weight of these salt-water eels " (T. Southwell). Paget has likewise remarked that eels are found in Yarmouth at the harbour's mouth and even at sea. It has been observed that an eel will live and grow in any water, however warm, and though it prefers a muddy or boggy bottom, such is not indispensable. It requires no special food, being omniverous, is an excellent scavenger, besides capturing living prey. It grows rapidly, while the young are easily transported. But it is found undesirable in rivers where gill-nets are much employed, as it eats the captives. As food. Are largely eaten potted, stewed, or in eel-pies ; are rather rich, wholesome and nutritious, except when captured near drains, when they ought to be avoided. "Very seldom eaten in Orkney" (Low). The Jews reject the eel although they are aware that it has scales. Elvers " may be eaten boiled in milk and pressed into a sort of cheese" (Ball). Fancy, as regards their appearance somewhat resembling a snake, causes many to reject these fish as food, although they are otherwise esteemed by the South Britons but loathed by those in the North, while in some parts of Ireland the supposition seems still to hold good that they are the lineal descendants of the serpents on which St. Patrick served a writ of ejectment, depriving them of any local habitation on dry land. A tradition exists in Cambridgeshire that when the priests refused to accede to the Pope's order to put away their wives, the latter, as well as their offspring, were turned into eels, whence originated the name Ely ! Their skins, in the Orkneys, are worn around the ankles as a preservative against cramps. Even the Ancients were super- stitious respecting eels, deeming them to be the embodiment of evil spirits. Highly esteemed by the Greeks and Romans, they were rejected by the Egyptians, but enrolled among their numerous gods, and esteemed by most people, except Jews and Scotch. They are always in season, but least in winter and are worst in May. Uses. Their skins, oiled and dried, are used in Tartary as glass. Diseases and causes of destruction. Their greatest enemies, irrespective of man, are otters, polecats, and rats, both of which attack them in winter when dormant. Herons and swans likewise eat them, as well as pike, salmon, and large trout. A water spaniel has been known to feed greedily on young eels waiting to ascend a pass. But herons have not invariably captured eels with impunity, as it is on record how one pierced through the eye by the bill of its captor, twisted itself round its neck and strangled it during its dying agonies. It is asserted that tar in the water destroys or repels eels. Thus they were formerly abundant in the harbour at Mevagissey, but since boat-building has been much carried on they have disappeared, the water now being constantly polluted with tar. A disastrous epidemic among the eels has been observed this summer (1882) in the Nakskoofjord in Laaland, an island of considerable size in the Baltic, MUR^ENID^E. 249 belonging to Denmark. " The eels are dying away in enormous numbers without suffering from any apparent disease. Many thousands of dead eels could be seen a few days ago along the strand between Sandby Sletniis and Rosniis, only a few miles distant from each other. Great quantities of eels forwarded as usual to the German ports in the East Sea were discovered dead upon the arrival of the transports at their destination, although when shipped they all appeared to be in a fresh and healthy condition. The eel fishery, which is of considerable importance in the fiords of Laaland, has therefore collapsed altogether this season. All the foreign eel fishermen who have been in the habit of frequenting the island have returned home. Nothing has as yet been ascertained which might throw any light upon the cause of the death of the eels " (V. B., in Land and Water, July 15th, 1882). An epidemic is reported to have attacked pike and eels in the river Barrow. The latter fish were seen very lifeless for a day or so, and subsequently dead in shoal water, the under part of the body, from the mouth to the tail, being speckled with blood-red spots, and the mouth sometimes full of coagulated blood. Numbers are killed and eaten by rats and polecats in the winter. They are very much disturbed by electricity. In the winter they come to the surface for air, and polecats have been observed to hunt for them. Mr. Bannister (Zoologist, 1846) observes, that " in tracing the foot-prints of the polecat, it will soon be ascertained that he halts at every hole or opening he meets with in the ice, and at once commences fishing, by introducing a forefoot into the water, and no doubt groping all round under the ice as far as he can reach in search of such eels as may have come to the aperture for air." Habitat. Generally distributed in Europe, except in the Arctic regions, the Danube and its tributaries, the Black Sea, and the Caspian. In the Orkneys eels " are common in all our lochs, bums, and in the sea. They are found in many of our lochs, especially where no other fish are, and even in those whose efflux into the sea is over such precipices as to allow of no passage for any living thing, which puzzles many of our country sages to account for their getting there ; and indeed this is no easy task, if we do not consider the manners of the eel : how difficult it is to be retained in the claws, or even the stomachs of birds which prey upon it ; how tenacious of life it is, which makes it capable of being carried a great way without being the worse ; and if dropped, its ability in this case to seek out a proper habitation for itself " (Low). In Ireland it is abundant both in the fresh waters and around the coast. In the north they commence taking them in large numbers about August. The greatest number Thompson states he had heard of being captured at Toome in one night was 70,000. Mr. Ogilby says that he has only detected the broad- nosed form in the rivers of the Donemanagh district. The fry run up in June, and are eaten by larger eels, trout, etc. As to the size which eels obtain, many of the largest recorded examples are probably congers. August 17th, 1866, one netted the previous day in the River Bure, Homing (? Norfolk), was 3 feet 8 inches long, and 10 inches in girth at the thickest part, and 7f lb. weight (T. E. Gunn, Zool. 1866, p. 510). Mr. Clarke Kenedy observed one from Downham 5 feet 8 inches long and 36 lb. weight (Zool. 1868, p. 1061). The largest seen by Buckland weighed 10 lb., and I have not personally observed any larger. The example figured is a female from Norfolk, 13-* inches in length. 250 PHYSOSTOMI.

Length of head 7 to 8, height of body 16 to 20 in the total length. Body anteriorly rounded, becoming compressed in its posterior portion. Head depressed. Mouth wide, the upper jaw very slightly the longer, its cleft extending to below the middle of the orbit. The posterior nostril patent, the anterior tubular. Teeth cardiform in the upper jaw, one regular row of teeth of the same size and placed close together form a cutting edge : a short band on the vomer : cardiform likewise in the lower jaw similar to those in the upper Fins the dorsal commences above the last quarter or end of the pectoral : the anal in the middle of the total length. Colours generally grayish, becoming lighter or even white beneath. A row of white spots mark the openings from the lateral- line. The margins of the vertical fins black. Varieties. In colour, the body may be dark and the vertical fins blackish or with a black edge : or the whole fish may be uniformly black, due to the character of the locality where it resides. Couch alludes to a rock on the coast of Cornwall about five leagues from land, and rising up from a large plain of submerged sand. The summit of this rock is full of gullies shaded with weeds, and congers caught there are always black, while those taken close to its base are always white. Occasionally these fish are spotted with white. " In 1876 a conger of about 201b. weight, of a lead colour, approaching to white, was brought in from the deep sea and placed in a large wicker basket close to land : in six weeks he was as black as he possibly could be " (Dunn). In form. In some there is a deficiency of the upper jaw or snout, while the dorsal fin is frequently deformed, the anterior portion being often absent or malformed, sometimes only a few rays existing near the tail. Occasionally the tail is found to end without any fin. Navies. Conger, Haaf-eel (and Easgann faragidh, Celtic) Moray Firth. Evil-eel, Aberdeen (Sim). Cungyr or hunger, Mor Lysoioen and Cungyren, Welsh. Be Zee- paling, Dutch. Congre commun, French. Habits. Prefers deep waters where the bottom is rocky, or sandy spots surrounded by rocks which are covered by weeds. Is found from the borders of the tide up to fifty fathoms or more, but it very rarely ascends into fresh water ; and although it appears to frequent favourite localities, still it is more common there at some times than it is at others. It is most active and appears to principally feed at night-time, even the presence of a bright moon has been known to interfere with the success of the fishing. It enters lobster pots to secure the contents, and is very destructive to soles and plaice in Cornwall. When in boats it feels about with its tail, and, if able, will lay hold of the gunwale with it, and so lift itself overboard, and this is one reason why the fisherman at once knocks it on the tail or over the vent when captured : it is by means of the tail that it likewise makes its exit from a crab pot in which it has entered to devour the contents ; it thrusts its flattened tail between the willow-rods of which it is composed and thus pushes itself backward through the opening. It is sometimes left stranded an hour or more by the tide, but this does not appear to occasion any inconvenience, while it will even conceal itself under the sand, awaiting a return of the tide. In the Moray Firth Gordon remarks that the fishermen believe that this fish is fond of swimming after newly tarred boats. The conger is very sensible to atmospheric changes, and is inert during cold weather, while prior to storms it is more than usually active. During severe frosts conger have been seen floating down rivers half dead or " blown," this term signifying the air-bladder being tightly distended. Near Cork, in 1841, many died of cold ; others were readily captured where the water was from forty to sixty feet deep and brackish. Pennant observes that congers and eels in general are particularly fond of carcases of any kind, being frequently found lodged in such that are accidentally taken up. In an aquarium it will even devour dog-fishes, swallowing its prey head first ; while at Southport they could only keep sturgeons, angel-fishes, skate, 252 PHYSOSTOMI. and huge turbots safe in such company, their digestion being very rapid. It does great injury to the net- fishermen, tearing the captives out of the meshes. It feeds upon fish, especially pilchard, hake, and herring along the south coast, lobsters, crabs, and, in short, almost any form of animal life. Templeton recorded that a vessel loaded with salt herrings was wrecked on the coast of Rathlin, and these fish gorged themselves on them in great numbers, and for several days subsequently were washed ashore dead. Mr. Ogilby informs me of one 58^ lb. weight, and measuring over six feet long, which was taken in a net at Portrush, July 21st, 1876, while in the act of trying to swallow a marked 6 lb. salmon, which it has succeeded in doing so far as the mesh of the net. Mr. Dunn, at Mevagissey (October 9th, 1883), found they had swallowed stones from one to four ounces in weight, and also that it was a common occurrence as observed at the fish factory. Eleven days subse- quently, on a conger being hooked, it tried to free itself by ejecting something from its stomach, but the stone which it was trying to force out was broader one way than the other, evidently the small end having been swallowed first, but on coming up it turned and completely choked the conger; and after death, so firmly was it found jammed that after the fish's head was cut off, it could not be moved, and is still imbedded in the skull of the creature. It would appear likely that these stones have been swallowed for the purpose of obtaining the animal life attached to them, while they are subsequently ejected. Mr. Dunn, at Mevagissey, kindly kept a list of the various kinds of food taken from congers' stomachs in one day in August at the fish factory. Goldsinny wrasse, skulpin, lesser sand launce, father lasher, one-spotted goby, pollachs, rocklings of sorts, powers, lesser fork-beard, carter, pilchards, very small congers, pipe fishes, small squid, five varieties of crab including the hermit-crab, a whelk without its shell, and other animal substances. Small congers are frequently found in the stomachs of their larger relatives, while it is not uncommon for a small one, after having been hooked, to be swallowed by one which exceeded it in size : while the five-bearded rockling is a favourite food, also the large pipe fish. Many instances, observes Thompson, have been recorded of the decapitated heads of these fish closing upon foreign bodies being inserted between the jaws ; and Mr. Patterson of how a boy, seeing on the shore the head of one of these fish just left by fishermen, pushed his toe into it ; his yells soon brought assistance and release. Means of capture.^- Along our south coast, although occasionally taken handlining, it is chiefly caught by long lines or bulters baited with pilchards, mackerel, or sand launce : its mouth is rather tender for handlining, still this is the favourite method of pursuing it in the Channel Islands ; hut at the sea bottom it gorges the bait, which must be quite fresh. A conger can bite through a cord as thick as the finger, and twist the line round into a ball, and in this manner often drags the hook from the jaws. In most places on being captured it is knocked on the head or over the abdomen ; but not so in the Channel Islands, where such a proceeding, it is considered, would spoil its appearance. Taken in Ireland mostly in May and June. Thompson mentions that congers have been known to destroy 5 worth of nets in a single night, and seven or eight hooks have been removed from a single fish. Baits. Red sea bream, pieces of almost any fish, as pilchards, herrings, and likewise cuttles. At Portrush, where it is very common, Mr. Ogilby observes that the lines set for it are only let down about an hour and in a slack tide : the bait should be perfectly fresh, as it will not look at anything stale! Breeding. In June, 1876, a female died in the Southport Aquarium, which weighed 15jlb., while the ova were full 7 lb., showing a total of 6,336,512 eggs. Dr. Otto Hermes found 3,300,000 in one, the ovaries of which weighed 22-| lb. Yarrell asserts that they spawn in December and January. In Germany, Otto Hermes refers to female congers dying, unable to deposit their ova, while one at Frankfort-on-the-Maine burst in consequence of the unnatural development of its ovaries. It would seem to be a rapid-growing fish when abundantly supplied with food, thus Mr. Jackson at the JSouthport Aquarium observed that in about sixteen MUELENID^E. 253 months the conger-eels have increased from about 7 or 8 lb. each to something like 25 lb. or 30 lb., and one which died in March, 1880, had grown in 5^- years from 2 or 31b. to 901b. weight. The supposed male organs of the common eel were observed by Syrski, as already described (page 247), but no one had detected spermatozoa in them. It was not until June 20th, 1880, that Dr. Otto Hermes finally set this question at rest respecting congers, when he found on cutting into Syrski's organ, that a white fluid flowed out, which, under the microscope with a power of 450 diameters, showed a great number of spermatozoa in the liveliest motion, and in which head and tail were evidently visible. The male conger is considerably smaller than the female, as has been observed in the common eel. Fisheries. During the fourteenth century in the West of England, this was an important dish, and was even received as the chief rent at underletting of land. At Sir T. F. Aubyn's, Mount's Bay, Cornwall, is a large one stuffed, which was paid as a heriot according to the terms under which the land was beld. Pennant observes that the following quantities were sent from Mount's Bay in Cornwall, in five years : 1756, 46 cwt. ; 1757, 164 cwt. ; 1758, 164 cwt. ; 1759, 213 cwt. ; 1760, 71 cwt. Before congers decreased off our shores or the sale became limited, they were exported to Spain and Portugal. Round the Channel Islands and among the rocks in the vicinity congers abound, and King John in the charter of privileges to the people of this locality dwelt upon the right to capture and salt these fish, and prior to the extension of the Newfoundland fisheries this was very valuable. As food. Donovan considered its flesh to be simply delicious when roasted. The fat around its milt and roe is employed in some particular cookery due to its not possessing any disagreeable taste or smell. Much of the "stock" for turtle soup for hotel or public dinner tables is said to be made from conger. As food it, in common with the eel, is rejected in many parts of Scotland and the West of England, but in Edinburgh it finds a ready sale : in the Channel Islands the black variety is preferred. Uses. Conger doust is a local term for dried conger ; the Portuguese and Spaniards used to employ these dried congers after they had been ground into a powder for the purpose of thickening and giving a relish to their soup. Small ones, according to Pennant, were slit and then hung on a frame until dry, for having much fat it is necessary all should exude before they are fit for use ; they were then stitched together by their edges into a sheet. In Ireland the skins are preserved and employed for the hanging of flails, etc. Diseases and causes of destruction. Sudden cold is often very destructive to congers, which become blown, so drift on shore and are left dead by the tide or knocked on the head and captured, or fall a prey to the lower animals. Otters in the Orkneys bring them on shore and leave them after they have eaten a small portion, subsequently the country people search for these. Porpoises, likewise, feed on them : thus, on April 20th, 1881, one weighing 35 lb. ran ashore and several yards up the beach of Colwyn Bay when pursued by one of these animals and, after a tough fight, was secured by Captain Davis, who gaffed it with a sail-hook. Dareste refers to rickets, rachitis, existing in these fish. Such fish are remarkable by reason of the great reduction in the number of teeth, and remain smaller than is natural. Habitat. This fish has a very wide geographical range, extending from the coasts of Europe, the Mediterranean, and the shores of the Atlantic Ocean, to the East Indian Archipelago, Japan and Tasmania. In the Orkneys the largest measure about 6 feet in length (Low). It is common round the coasts of Britain and Ireland, and abundant along our southern shores. This fish attains a large size : in October, 1877, one which was 6| feet long was captured at Portrush, in Ireland, which weighed 53 lb. In January, 1880, one weighing 84 lb. was taken in a net at Burnham, in Somersetshire. Borlase alludes to one near Mount's Bay of 100 lb. weight ; Couch to another of 104 lb. ; Buckland to one at Mevagissey, by Dunn. 112 lb.; and in 1879 a conger weighing 128 lb. and 8 feet 3 inches long was received in the London market ; Donovan asserts one of 130 lb. was captured at the Nore. 254 PHYSOSTOMI.

A tubular nostril on either side of the upper surface of the snout : the posterior nostril a round orifice opposite the antero-superior edge of the eye, while it may or may not be furnished with a tube. Teeth well developed, and either acute or molariform : the maxillary teeth may be in one or two rows. Dorsal fin elevated, or not so ; the end of the tail surrounded by fin, and is occasionally rudimentary : pectorals absent. Geographical distribution. Seas of temperate and tropical regions, some species ascending tidal rivers. One form has been captured off our coast. The spotted sea-eel, Ophisurus ophis, an inhabitant of the Indian Ocean, was included by Merret (Pinax, p. 185), subsequently by Sibbald (Scot. 23), and also by Berken- hout (Syn. i, p. 185) among the British fish, but the authority in all is omitted. It may, however, have been due to the capture of a Murozna helena at some antecedent date. The dentition of these fish alters considerably with age, while it is not always identical in every individual of the same species. They are reputed to attack fishermen and others when in the water, a character, Mr. Carrington (Zoologist, September, 1876) thinks, they do not deserve. 1. Muraena helena, Plate CXLIII.

D, C, and A = 552, Vert. 140-143. Height of body varying from 9 to 12 or more times in the total length and the length of the head about 7 to 12 in the same distance. Eye diameter about T V in the length of the head and 3 diameters from the end of the snout. _ Anteriorly the body of this fish is rounded, becoming flattened posteriorly : its skin is very thick, snout pointed, the cleft of the mouth deep and extending behind the eye : the upper jaw rather longer than the lower. A row of pores along both jaws. Both nostrils tubular, the anterior the longer. Teeth in a single row, strong, compressed and MITILENID^. 255 pointed : those in the premaxillaries, and the canines in the lower jaw a little larger than the lateral teeth : 17 to 19 along either side of the mandible. A row along the vomer, the anterior of which are the largest. Gill-opening small. Vent situated a little in front of the middle of the total length. Colours a rich chocolate brown, lightest along the lower surface, and covered with irregularly shaped yellow marks or spots : near the tail the colours frequently take on a banded appearance. Gill-opening in a black spot as are also the corners of the mouth, and folds of skin on the throat which resemble black lines. The yellow spots are also extended on to the vertical fins. Varieties. There are many forms of colour in this fish, some being spotted others plain. Name. The Murry. Habits. Generally reputed fierce and voracious, but capable of being domesti- cated, and even it is asserted of showing affection, while Mr. Carrington considers it usually of the latter description. It frequents holes in rocks, and takes its food not by reiterated snaps but in a gentle and peculiar way, by a curiously quiet movement of the head, so as to bring the cheek down upon the object about to be eaten, seizing it with the side of its mouth and never by the front. It is very retentive of life and most readily dispatched by a blow on its tail. A wound from the teeth of this fish has been deemed dangerous, and we have the tale handed down to us, that on one occasion, when Augustus Ca?sar dined with his favourite follower Vedius Pollio, and a slave chanced to break a valuable crystal wine vase, the latter flung himself at the emperor's feet and supplicated that he might not be thrown to the Muraenas. On inquiry it was found that his master in this manner treated offending slaves who broke the decanters. The emperor having heard the suppliant, first set him free, next saw the eel-ponds filled in, and lastly had all the crystals broken in the presence of the guests. As it gets old it is said occasionally to have a propensity to become fat and even to float on the surface. It is said to delight in waging war with crabs, cuttles, and congers : it devours small fishes, mussels and shrimps. Vivaria. Kept by the Romans as delicacies, and objects of amusement or even of affection. This fish is found to live and even thrive in fresh water. As food. A delicacy, its flesh being white and of good flavour. Habitat. It is common in the Mediterranean, especially off the coasts of Italy and Sicily. Not rare at Madeira (Lowe). An example, 4 feet 4 inches long, was captured on a line at Polperro, October 8, 1834, and brought to Mr. Couch, who subsequently noted in his journal that Mr. Laughrin in 1866 informed him that the preceding spring a large example of this fish was caught in a trammel at Fowey, and cut up as bait for crab-pots. The example figured died in the Royal "Westminster Aquarium, and I am indebted for it to Mr. Carrington, f.l.s. 25G LOPHOBRANCHII. Order IV LOPHOBRANCHII, Currier. Fishes possessing a dermal, segmental skeleton, and the opercular pieces reduced to a single plate. Gill-openings small : gills consisting of small and rounded tufts attached to the branchial arches. Muscular system very slightly developed. Snout produced : mouth terminal, but small. Teeth absent. Air- bladder stated to be destitute of a pneumatic duct (but it is present in some forms, as Syngnathus acus). The fishes which belong to this order, and popularly known as pipe-fishes and sea-horses, normally swim in a vertical position, the dorsal fin beinq- the principal propeller, and which while in motion is rapidly undulated from end to end. The tail fin, remarks Gray, seems to be used rather as a foot than as an organ of pro- pulsion, and when the species with a rayed caudal fin employs this part, it expands the rays giving the end of the tail the appearance of a webbed foot. The action of the mouth is similar to that of a common syringe, due to the dilatation of the throat ; the water enters the tubular-formed mouth, while it is ejected again by compressing and so emptying the cavity. As regards
