Generic Characters. — Head smooth ; body covered with scales ; two dorsal fins, the first supported by rays, the second fleshy, without rays ; teeth on the vomer, both palatine bones, and all the maxillary bones ; branchiostegous rays varying in number, generally from ten to twelve, but sometimes unequal on the two sides of the head of the same fish. THE SALMON is so well known for its quality as an arti- cle of food, as well as for the immense quantities in which it is taken, that it requires no other claims to recommend it strongly to our notice ; and probably, in no country * The family of the Salmon and Trout. VOL. II. R 2 SALMONID^E. of the world, in proportion to its size, are the fisheries so extensive, or the value of so much importance, as in the United Kingdom. The history of the Salmon, and of the species of the genus Salmo, in this work, will extend to a considerable length ; and some doubts existing as to the extent of their identity with the species of the Salmonida generally which are taken in the rivers or lakes of other countries of Europe, from the want of specimens with which to make actual comparative examination, the account of the species here inserted will be confined more particularly to a detail of what is known of them in this country only. Of the species existing in this country, the characters and specific distinctions admit of considerable detail : too much reliance has been placed upon colour, without resorting sufficiently to those external indications, founded on organic structure, which may with greater certainty be depended upon. In the scale of the relative value of parts affording cha- racters for distinction, the organs of digestion, respiration, and motion are admitted by systematic authors to hold high rank ; and in the hope to induce sportsmen to become zoologists — so far at least as to enable them to determine the various species they may meet with by a reference to those external characters which are the most important, — the specific distinctions in the genus Salmo will be illus- trated by referring to the number and situation of the teeth, the form of the different parts of the gill-covers, and the size, form, and relative situation of the fins. The outlines here introduced represent a front view of the mouth, and a side view of the head, of a common Trout. Of the first figure on the left hand, No. 1 marks SALMON. the situation of the row of teeth that are fixed on the cen- tral bone of the roof of the mouth, called the vomer : Nos. 2, 2, refer to the teeth on the right and left palatine bones ; and the row of teeth outside each palatine bone on the upper jaw are those of the superior maxillary bones : No. 3, refers to the row of hooked teeth on each side of the tongue, outside of which are those of the lower jaw-bones. The Trout is chosen as showing the most complete series of teeth among the Salmonida; and the value of the arrangement, as instruments for seizure and prehension, arises from the interposition of the different .rows, the four lines of teeth on the lower surface alternating when the mouth is closed with the five rows on the upper surface, those on the vomer shutting in between the two rows on the tongue, &c. The second figure represents, in outline, a side view of the head, of which No. 1 is the preoperculum ; No. 2, the operculum ; No. 3, the suboperculum ; No. 4, the interoperculum ; No. 5, the branchiostegous rays : the four 4 SALMONID.E. last parts together forming the moveable gill-cover. The different fins are sufficiently indicated by being coupled, when referred to, with the name of the part of the body of the fish to which they are attached. The external appearance of the adult Salmon during the summer months, when it is caught in the estuaries of our large rivers, is too well known to require much description. The upper part of the head and back is dark bluish black ; the sides lighter ; the belly silvery white ; the dorsal, pectoral, and caudal fins dusky black ; the ventral fins white on the outer side, tinged niore or less with dusky on the inner surface ; the anal fin white ; the small, soft, fleshy fin on the back, without rays, called the adipose, fat fin, or the second dorsal fin, is of the same colour nearly as the part of the back from which it emanates. There are mostly a few dark spots dispersed over that part of the body which is above the lateral line, and the females usually exhibit a greater number of these spots than the males. These colours, differing but little, are, however, in a great degree common at the same period of the year to the three species that are the most numerous, as well as the most valuable ; namely, the true Salmon, the Bull- Trout, and the Sea or Salmon Trout ; which are also fur- ther distinguished from the other species of the genus Salmo by their seasonal habit of moving from the pure fresh water to the brackish water, and thence to the sea, and back to the fresh water again, at particular periods of the year. Further specific distinctions are therefore necessary ; and those that will be pointed out as existing constantly in these species will, it is hoped, enable observers to iden- tify not only each of these, but also the other species of the genus, at any age or season. SALMON. The vignette above represents the form of the different parts of the gill-cover in the three species just named ; of which the figure on the left hand is that of the Salmon, the middle one is the gill-cover of the Bull-Trout, and that on the right hand is the gill-cover of the Sea or Salmon Trout : the differences are immediately apparent when thus brought into comparison. In the Salmon, the posterior free edge of the gill-cover, as shown in the left-hand figure, forms part of a circle ; the lower margin of the suboperculum is a line directed obliquely upwards and backwards : the line of the union of the suboperculum with the operculum is also oblique, and parallel with the lower margin of the suboperculum ; the interoperculum is narrow vertically, and its union with the operculum is considerably above the line of the junc- tion between the suboperculum and the operculum. The teeth of the Salmon are short, stout, pointed, and re- curved : as stated in the generic characters, they occupy five situations at the top of the mouth ; that is, a line of teeth on each side of the upper jaw, a line on each palatine 6 SALMONID^E. bone, with a few only on the vomer between the palatine bones : the teeth on the vomer seldom exceeding two in number, sometimes only one, and that placed at the most anterior part ; no other teeth extending along the vomer as in the Salmon-Trout, and more particularly so in some of those Trout that do not migrate. The inner surface of the pectoral fin is in part dusky : the tail very much forked when young ; the central caudal rays growing up, the tail is much less forked the second year, and by the fourth year it is become nearly or quite square at the end. The descriptions of the gill-covers of the other species will be given in the account of the fish to which they belong ; but it may be remarked here, that looking at the form of the three gill-covers, it will be obvious that a line drawn from the front teeth of the upper jaw to the longest backward projecting portion of the gill-cover, in either spe- cies, will occupy a different situation in respect to the eye ; that the line will fall nearest the centre of the eye in the first, that of the Salmon, and farthest below it in the second, that of the Bull-Trout. As further specific distinctions in the Salmon, I may add that, according to Dr. Richardson, the csecal appen- dages are in number from sixty-three to sixty-eight; and several observers have stated the number of vertebrae to be sixty, which I have repeatedly found to be correct. Commencing, then, with the true Salmon, which ascend the rivers, in the state as to colour before mentioned, sooner or later in the spring or summer months, it is observed that some rivers are much earlier than others, the fish in them coming into breeding condition and beginning to spawn at an earlier period. Rivers issuing from large lakes afford early Salmon, the SALMON. 7 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 be- ginning to fail. " The causes influencing this," says Sir William Jardine, to whom I am indebted for much valuable information on the Salmonida, as well as many specimens, " seem yet undecided ; and where the time varies much in the neighbouring rivers of the same district, they are of less easy solution. The Northern rivers, with little exception, are, however, the earliest, — a fact well known in the London markets ; and going still farther north, the range of the season and of spawning may be influenced by the latitude.11 Artedi says , "in Sweden the Salmon spawn in the middle of summer." " It has been suggested that this variation in the season depended on the warmth of the waters ; and that those Highland rivers which arose from large lochs were all early, owing to the great mass and warmer temperature of their sources, — that the spawn there was sooner hatched. There are two rivers in Sutherlandshire which show this late and early running under peculiar circumstances. One, the Oikel, borders the county, and springs from a small alpine lake, perhaps about half a mile in breadth ; the other, the Shin, is a tributary to the Oikel, joins it about five miles from the mouth, but takes its rise from Loch Shin, a large and deep extent of water, and connected to a chain of other deep lochs. Early in the spring, all the Salmon entering the common mouth diverge at the junction, turn up the Shin, and return as it were to their own and warmer stream, while very few keep the main course of the Oikel until a much later period." Dr. Heysham, in his Catalogue of Cumberland Animals, 8 SALMONID.E. has supplied similar evidence. " The Salmon," it is there observed, " is plentiful in most of our rivers, in all of which they spawn ; but they evidently prefer, during the winter and spring, the Eden to the Esk, the Caldew, or the Peteril. Although the Esk and the Eden pour out their waters into the same estuary, and are only separated at the mouths by a sharp point of land, yet there is scarcely an instance of a new Salmon ever entering the former until the middle of April or beginning of May. The fishermen account for this curious fact from the different temperature of these two rivers ; the water of the Eden, they allege, being considerably warmer than the water of the Esk ; which is not altogether improbable, for the bed of the Esk is not only more stony and rocky than the Eden, but is likewise broader, and the stream more shallow ; consequently its waters must be somewhat colder in the winter season. It is an undoubted fact, that snow water prevents the Salmon from running up even the Eden : it is probable this cir- cumstance may have considerable effect in preventing them from entering the Esk till the beginning of summer, when the temperature of the two rivers will be nearly the same. The Peteril joins the Eden a little above, and the Caldew at Carlisle ; yet up these rivers the Salmon never run unless in the spawning season, and even then in no great num- bers." The number of fish obtained in the spring in a proper state for food is small compared with the quantity procured as the summer advances. During the early part of the season, the Salmon appear to ascend only as far as the river is influenced by the tide, advancing with the flood, and generally retiring with the ebb, if their progress be not stopped by any of the various means employed to catch them, which will be explained hereafter. It is observed SALMON. 9 tliat the female fish ascend before the males ; and the young fish of the year, called Grilse till they have spawned once, ascend earlier than those of more adult age. As the season advances, the Salmon ascend higher up the river beyond the influence of the tide : they are observed to be getting full of roe, and are more or less out of condition according to their forward state as breeding fish. Their progress forwards is not easily stopped ; they shoot up rapids with the velocity of arrows, and make wonderful efforts to surmount cascades and other impediments by leaping, frequently clearing an elevation of eight or ten feet, and gaining the water above, pursue their course. If they fail in their attempt and fall back into the stream, it is only to remain a short time qui- escent, and thus recruit their strength to enable them to make new efforts. These feats of the Salmon are frequently watched with all the curiosity such proceedings are likely to excite. Mr. Mudie, in the British Naturalist, describes from personal observation some of the situations from which these extra- ordinary efforts can be witnessed. Of the fall of Kilmorac, on the Beauly, in Invernesshire, it is said, " The pool below that fall is very large ; and as it is the head of the run in one of the finest Salmon rivers in the North, and only a few miles distant from the sea, it is literally thronged with Salmon, which are continually attemping to pass the fall, but without success, as the limit of their perpendicular spring does not appear to exceed twelve or fourteen feet : at least, if they leap higher than that they are aimless and exhausted, and the force of the current dashes them down again before they have recovered their energy. They often kill them- selves by the violence of their exertions to ascend ; and sometimes they fall upon the rocks and are captured. It is indeed said that one of the wonders which the Erasers of VOL. IT. c 10 SALMONID.E. Lovat, who are lords of the manor, used to show their guests, was a voluntarily cooked Salmon at the falls of Kilmorac. For this purpose a kettle was placed upon the flat rock on the south side of the fall, close by the edge of the water, and kept full and boiling. There is a considerable extent of the rock where tents were erected, and the whole was under a canopy of overshadowing trees. There the company are said to have waited until a Salmon fell into the kettle and was boiled in their presence. We have seen as many as eighty taken in a pool lower down the river at one haul of the seine, and one of the number weighed more than sixty pounds." The fish having at length gained the upper and shallow pools of the river, preparatory to the important operation of depositing the spawn in the gravelly beds, its colour will be found to have undergone considerable alteration during the residence in fresh water. The male becomes marked on the cheeks with orange-coloured stripes, which give it the appearance of the cheek of a Labrus ; the lower jaw elon- gates, and a cartilaginous projection turns upwards from the point, which, when the jaws are closed, occupies a deep cavity between the intermaxillary bones of the upper jaw ; the body partakes of the golden orange tinge, and the Salmon in this state is called a red-fish. The females are dark in colour, and are as commonly called black-fish ; and by these terms both are designated in those local and precautionary regulations intended for the protection and preservation of the breeding fish. The process of spawning has been described by various observers. " A pair of fish are seen to make a furrow, by working up the gravel with their noses, rather against the stream, as a Salmon cannot work with his head down stream, for the water then going into his gills the wrong way, drowns SALMON. 11 him. When the furrow is made, the male and female retire to a little distance, one to the one side and the other to the other side of the furrow : they then throw themselves on their sides, again come together, and rubbing against each other, both shed their spawn into the furrow at the same time. This process is not completed at once ; it requires from eight to twelve days for them to lay all their spawn, and when they have done they betake themselves to the pools to recruit themselves. Three pairs have been seen on the spawning-bed at one time, and were closely watched while making the furrow and laying the spawn."* The following extracts are made from a valuable paper by Dr. Knox, published in the Transactions of the Royal Society of Edinburgh. " November 2. — Salmon are observed to be spawning in the various tributary streams of the Tweed which join that river from the north, and a pair are watched. The ova observed to be deposited near the sources of the stream on the 2nd of November, and covered up with gravel in the usual way." " February 25, or a hundred and sixteen days after being deposited, the ova, on being dug up, are found to be unchanged. If removed at this time, and preserved in bottles filled with water, the developement of the egg may be hastened almost immediately by being put into warm rooms : it is not necessary to change the water. The fry so hatched, i. e. artificially, cannot be preserved alive in bottles longer than ten days ; they eat nothing during their con- finement." " March 23. — The ova now changing ; the outer shell cast ; the fry are lying imbedded in the gravel, as fishes * Ellis on the Natural History of the Salmon. 12 SALMONrD.E. somewhat less than an inch in length, being now twenty weeks from the period of their deposition." "April 1. — On reopening the spawning-bed, most of the fry had quitted it by ascending through the gravel. During a former series of observations I have found the ova imbedded in the gravel unchanged on the 10th of April, and as fry or fishes, but still imbedded in the gravel, on the 17th : they were taken that year, with fly, as Smolts, on the 22nd of April, about the size of the little finger." Some specimens of Salmon fry now before me, with a portion of the ovum still attached to the abdomen of each fish, measure one inch in length : the head and eyes are large ; the colour of the body pale brown, with nine or ten dusky grey marks across the sides. These dusky patches, longer vertically than wide, are common, I have reason to believe, to the young of all the species of the genus Salmo. I have seen them in the young of the Salmon, Bull-Trout, Salmon-Trout, Parr, Common Trout, and Welsh Charr. I have never had an opportunity of examining the young of the Northern Charr, or the Great Lake-Trout ; yet I have no doubt but that, when only two or three inches long, they also are marked in the same manner. In a specimen of the young of the Salmon six inches long, these transverse marks are still observable when the fish is viewed in a particular position in reference to the light ; and if the scales are removed, the marks are much more obvious. In a Parr of the same length these marks are still more conspicuous ; they are also very distinct in the Common Trout and in the Welsh Charr for a consider- able time ; and as far as my own examination has gone, these lateral markings observable in the fry of the species of Salmo are lost, or become indistinct, sooner or later, depend- ing on the ultimate natural size attained by the particular SALMON. 13 species : thus, they are soonest lost in the Salmon and in the Bull-Trout, and are borne the longest in the Common Trout and Parr ; indeed, I have never seen the Parr, at any age or size, without some trace of the remains of these markings. It is this similarity in markings and appearance of the fry which has caused the difficulty in distinguishing between the various species when so young; and experi- menters, believing they had marked young Parr only, have been surprised to find some of their marked fish return as Grilse, young Bull-Trout or Whitling, Salmon-Trout, River- Trout, and true Parr. There are striking examples in other animals of this similarity in the markings, or family likeness, in the young of the various species of the same genus, however different may be the colours of the parent animals. The young of the lion and the puma are as much marked for a time as the young of the tiger and leopard, or, indeed, of any of the other cats, whether striped or spotted ; and the young of all deer are said, and many are known to be, spotted, though it is also known that the greater number of the adult animals are perfectly plain. To return to the Salmon. The adult fish having spawn- ed, being out of condition and unfit for food, are considered as unclean fish. They are usually called Kelts ; the male fish is also called a Kipper, the female a Baggit. With the floods of the end of winter and the commencement of spring they descend the river from pool to pool, and ultimately gain the sea, where they quickly recover their condition, to ascend again in autumn for the same purpose as before ; but always remaining for a time in the brackish water of the tide-way before making either decided change ; obtaining, it has been said, a release from certain parasitic animals, either external or internal, by each seasonal change ; those of the salt SALMONID.E. water being destroyed by contact with the fresh, and vice versa. The fry are observed to collect in small pools and mill-dam heads preparatory to quitting the river. The specimen from which the figure on the page was taken was obtained in the Thames, in which river they are occasionally caught in the season, with other fry of Salmonida, by fishermen who work at night with a casting-net on the gravelly shallows for Gud- geons to supply the London fishmongers. My own specimens of the young of the Salmon having been preserved in spirits, and the colours thereby affected, the following description is from Dr. Heysham's Catalogue before referred to, premising that some differences in colour may be expected in specimens from different rivers. " Length seven inches and a half ; circumference three inches and one-eighth : head dark green ; gill-covers fine silvery white, marked with a dark-coloured spot ; belly and sides up to the lateral line of the same silvery colour ; back and sides down to the lateral line dusky, inclin- ing to green ; sides above the lateral line marked with numerous blackish spots ; along the lateral line, and both a little above and beneath it, several dull obscure red spots : dorsal fin has twelve rays, marked with several blackish spots ; pectoral fin has twelve rays, of a dusky olive colour ; ventral fin eight rays of a silvery white ; anal fin ten rays of SALMON. 15 the same colour. When the scales were carefully taken off with a knife, the obscure red spots became of a fine vermi- lion, and were nineteen in number; and ten obscure oval bars of a dusky bluish colour appeared, which crossed the lateral line. In a young fry which has not acquired scales, these bars are very distinct." Whether the river be considered an early or a late river, the descent of the fry is said to take place much about the same time in all. It begins in March, and continues through April and part of May. It rarely happens that any Salmon fry are observed in the rivers late in June. The Smolt, or young Salmon, is by the fishermen of some rivers called a Laspring ; and various couplets refer to the fish, as well as to the time and circumstances under which the descent is made. The last spring floods that happen in May, Carry the Salmon fry down to the sea. And again, The floods of May Take the Smolts away. But the uncertainty of popular or provincial names is a source of great perplexity to the naturalist. The Laspring of some rivers is the young of the true Salmon ; but in others, as I know from having had specimens sent me, the Laspring is really only a Parr ; and it must also be recol- lected that the fry of two other species at least descend to the sea about the same time as those of the Salmon. The Salmon fry at first keep in the slack water by the sides of the river ; after a time, as they become stronger, they go more towards the mid-stream ; and when the water is increased by rain, they move gradually down the river. On meeting the tide, they remain for two or three days in that part where the water becomes a little brackish from the mix- 16 SALMONID^E. ture of salt water, till they are inured to the change, when they go off to the sea all at once. There, their growth appears to be very rapid, and many return to the brackish water, increased in size in proportion to the time they have been absent. Fry marked in April or early in May have return- ed by the end of June weighing from two to three pounds and upwards. The London markets during the latter part of June, and the months of July and August, exhibit fish of the year varying in weight from two to six pounds. I have one, here figured, that weighed only fifteen ounces, which, judging from its appearance when I bought it, that it had been to sea, is the smallest specimen I have ever seen that had been once to salt water. These small-sized fish, when under two pounds' weight, are called by some of the London fishmongers Salmon-Peal ; when larger, Grilse. These fish of the year breed during the first winter ; they return from the sea with the roe enlarged ; the ova in a Grilse being of nearly the same comparative size as those observed in a Salmon, but they mature only a much smaller number. The Grilse visit the estuary, remain- ing for a considerable time in the brackish water, afterwards in the tide-way above, ultimately pushing up to the sources of the tributary streams, and, as before observed, rather ear- lier in the season, in the same river, than the more adult fish. SALMON. 17 It has been a constantly received opinion, that all the young fish after their first visit to the sea return to the rivers in which they had been bred ; and numbers of marked fish are stated to have been retaken in their native rivers : but it is equally certain that some have been taken in other rivers not far off. The difficulty of supposing that they could find and return to the same spot after roving for miles along the coast remains to be solved. That they do thus rove for miles is proved by the thousands that are taken in nets placed in the bays along the coast. Very many Tweed Salmon have been caught opposite Hopetoun House on the Forth ; and a very successful fishing there is generally fol- lowed by a scarce one in the Tweed. It is therefore very probable, from the remarks of Dr. Heysham and Sir William Jardine, that if the fish happen to have roved far from the estuary of their native river, they run at the proper season up any stream, even the first they encounter, the temperature and condition of which are congenial to them. The growth of the Salmon from the state of fry to that of Grilse has been shown to be very rapid ; and the increase in weight attained during the second and each subsequent year is believed to be equal, if not to exceed, the weight gained within the first. The increase in size is principally gained during that part of the year in which the fish may be said to be almost a constant resident in the sea. That the food sought for and obtained to produce and sustain so rapid an increase of size must be very considerable in quantity, as well as most nutritious in quality, cannot be doubted. That the Salmon is a voracious feeder, may be safely inferred from the degree of perfection in the arrangement of the teeth, and from its own habits, of which proof will be adduced, as well as from the well-known habits of the species most closely allied to it ; yet of the many observers who have examined 18 SALMONJD^E. the stomach of the Salmon to ascertain the exact nature of that food which must constitute their principal support, few have been able to satisfy themselves. . Dr. Knox states, " that the food of the Salmon, and that on which all its estimable qualities, and, in his opinion, its very existence, depend, and which the fish can obtain only in the ocean, he has found to be the ova or eggs of various kinds of echino- dermata, and some of the Crustacea. From the richness of the food on which the true Salmon solely subsists, arises, at least to a certain extent, the excellent qualities of the fish as an article of food. Something, however, must be ascribed to a specific distinction in the fish itself:, for though he has ascertained that the Salmon-Trout lives very much in some localities on the same kind of food as the true Salmon, yet under no circumstances does this fish acquire the same exqui- site flavour as the true Salmon." That they occasionally, however, take other food, is also well known. Faber, in his Natural History of the Fishes of Iceland, remarks, " The common Salmon feeds on small fishes, and various small marine animals." Dr. Fleming says, " Their favourite food in the sea is the Sand Eel ;" and I have myself taken the remains of Sandlaunce from the stomach. Sir William Jardine says, " In the north of Sutherland a mode of fishing for Salmon is sometimes successfully prac- tised in the firths, where Sand Eels are used as bait : a line is attached to a buoy or bladder, and allowed to float with the tide up the narrow estuaries. The Salmon are also said to be occasionally taken at the lines set for Haddocks, baited with Sand Eels. At the mouths of rivers they rise freely at the artificial fly within fifty yards of the sea ;* and the com- mon earth-worm is a deadly bait for the clean Salmon. All the other marine Salmon are known to be very voracious ; and there is nothing in the structure of the mouth or strong SALMON. 19 teeth of the common Salmon, to warrant us to suppose that there is any material difference in their food." The follow- ing is an extract from a letter sent me by Sir William Jar- dine, dated St. BoswelFs, 15 April 1835 : — " The fisherman who rents this part of the Tweed, fishing with worm one day last week, had his hooks and tackle taken away by a fish. He put on a new set, and again with worm in ten minutes hooked and killed a Salmon with his former hooks and bait in his mouth. This will either prove extreme voracity, or little sensibility in the parts of the mouth. I have often heard fishermen mention a similar fact, but never before knew an instance on which I could depend." Several observers have borne testimony to the partiality of the Salmon to the Sandlaunce as food ; and I have a record by an angler of Salmon caught in the Wye with a Min- now. The present London season, 1835, has been more than of usually remarkable for large Salmon. I have seen ten dif- ferent fish varying from thirty-eight to forty pounds each. A notice appeared in the public papers of one that weighed fifty-five pounds ; and, from the inquiries made, there is rea- son to believe most of these large-sized Salmon were sent from the Tay. Salmon, however, of much larger size have been occasionally taken. Mr. Mudie has recorded one of sixty pounds. In a note to the history of the Salmon in several editions of Walton, one is mentioned that weighed seventy pounds ; Pennant has noticed one of seventy-four pounds : the largest known, as far as I am aware, came into the possession of Mr. Groves, the fishmonger of Bond-street, about the season of 1821. This Salmon, a female, weighed eighty-three pounds ; was a short fish for the weight, but of very unusual thickness and depth. When cut up, the flesh was fine in colour, and proved of excellent quality. #0 SALMONID^E. The Salmon of the largest size killed by angling of which I have been able to collect particulars, are, in the Thames, October 3, 1812, at Shepperton Deeps, Mr. G. Marshall, of Brewer-street, London, caught and killed a Salmon with a single gut, without a landing-net, that weighed twenty-one pounds four ounces. Sir H. Davy used occasionally to visit the Tweed for the sake of angling for Salmon. This river is famed for afford- ing amusement to the Salmon fisher, more especially from the middle of March to the beginning of May. u We have heard," says Mr. Stoddart, in his Art of Angling as prac- tised in Scotland, " that on one occasion Sir H. Davy hap- pened by good fortune to hit upon an immense fish, weigh- ing about forty-two pounds, immediately above Yair-bridge, and captured him after a severe struggle. This feat he makes no mention of in his Salmonia, although certainly wor- thy of some notice." Mr. Lascelles, in his Letters on Sporting, Part I. Angling, says at page £1, " The largest Salmon I ever knew taken with a fly was in Scotland : it weighed fifty-four pounds and a half." It may be stated generally, that Salmon pass the summer in the sea, or near the mouth of the estuary : in autumn they push up rivers, diverging to the tributary streams ; in winter they inhabit the pure fresh water, and in spring descend again to the sea. The question has frequently arisen, Could Salmon be preserved permanently in fresh water ? and from some facts to be adduced, it appears that they might, but not without some diminution in size or quality, or both. Mr. Lloyd, in his Field Sports of the North of Europe, vol. i. p. 301, says, u Near Katrineberg there is a valuable fishery for Salmon, ten or twelve thousand of these fish being taken annually. These Salmon are bred in a lake, and, SALMON. in consequence of cataracts, cannot have access to the sea. They are small in size, and inferior in flavour. The year 1820 furnished 21,817." A large landed proprietor in Scotland, whose name I do not know that I am at liberty to mention, wrote as follows: — E. and operculum smooth, without tubercles ; basal and as- cending marginal lines of the preoperculum forming nearly a right angle ; lateral line arched over the pectoral fin, then straight to the end of the tail : the scales are nearly round, small, and smooth ; the colours of the body a reddish sandy brown, varied with darker brown, and sprinkled over with white pearl-like specks, whence, probably, one of the names bestowed on this fish has originated : the under surface is smooth and white. The young are of a pale reddish brown, marked with very dark brown or black spots. The vignette represents the outline of the anterior part of a Brill with a malformed head. For the fish from which this sketch was taken, I am indebted to the kindness of Mrs. Nelson of Devonport. It was taken in that vicinity in June 1835, and was brought on shore alive. MULLEK's TOPKNOT.

SEVERAL modern authors have confounded the present fish with the species next to be described ; and Cuvier,* as well as Professor Nilsson,-f- have brought together the Pleu- ronectes hirtus of Muller, and the PL punctatus of Bloch, apparently considering them as the same fish. Muller doubted whether the punctatus of Bloch was the same as his fish, and notices the points in which they differ. The opportunity of examining some specimens very recently, » Regne An. t. ii. p. 341. t Prod. Ichth. Scand. p. 59, sp. 11. PLEURONEOTID^. confirms the existence of two distinct species on our shores. Though somewhat similar in the form of the body, the colouring, and the spots, there are still the following well- marked distinguishing specific characters. The hirtus of Muller, and those included in the syno- nymes here given, have the eye or coloured side only of the body rough ; the under side smooth ; the eyes and mouth small : the first ray of the dorsal fin not longer than the succeeding rays ; the ventral and anal fins united ; the dorsal and anal fins also connected to the tail by a membrane ; the tail short and rounded ; the scales of the body when de- tached higher than wide. The punctatus of Bloch, and the fishes included under the synonymes given with the next species, have both sides of the body rough ; the eyes large and prominent ; the mouth larger than in hirtus, and not placed so obliquely ; the first ray of the dorsal fin elongated ; the ventral and anal fins separated ; the tail rather long ; the scales of the body when detached wider than high. The hirtus of Muller appears to be the most common species of the two ; but neither occur very frequently. I have received a specimen from Dr. George Johnston, which was taken near Berwick Bay ; and I am indebted to Profes- sor Henslow of Cambridge for a drawing of one taken in the Medway. Dr. John Harwood, of St. Leonard's, possesses a specimen taken on the Sussex coast ; and both Colonel Mon- tagu and Mr. Hanmer obtained specimens in Devonshire. Mr. Couch considers it not an uncommon fish in the West of England, and has furnished me with two examples, from one of which the figure was taken. It appears to keep among rocks, where it is not readily distinguished, on account of the similarity in its colour to the seaweed ; and it is chiefly taken in the nets which are set for Red Mullet. In winter 245 the boys find small ones, not larger than a half-crown piece, in the pools left by the tide. This species of Flatfish does not probably attain any great size ; the largest examples I have seen not exceeding seven or eight inches in length. Mr. Baker, of Bridgewater, sent me a specimen, beautifully preserved, that had been taken in the Bristol Channel : and I have a record of one that was caught on the coast of the county of Down in Ireland. The whole length of the specimen described is five inches and one quarter ; the length of the head compared to that of the body, without the caudal rays, is as one to two and a half ; the breadth of the body, not including the dorsal and anal fins, half of the whole length : the form of the body, including both these fins, is rhomboid: the dorsal fin commences immediately over the upper lip, the rays lengthening by degrees, and being longest over the posterior third part of the body ; the pectoral fin small ; the ventral fins placed in a vertical line under the middle of the head, and attached to the commencement of the anal fin by a membrane : this latter-named fin commences under the line of the ascending posterior margin of the preoperculum : both dorsal and anal fin end on the same plane, and are connected to the fleshy portion of the tail by a membrane ; the tail small and rounded. The fin-rays in number are — D. 90 : P. 11 : V. 6 : A. 70 : C. 14. Vertebra 33. The mouth is small, the position almost vertical ; the teeth distinct, small, conical, and sharp : the diameter of the eye equal to one-fourth of the length of the head ; the upper eye placed behind the line of the lower to the distance of nearly one-half its width : the basal and ascending marginal lines of the preoperculum form an obtuse angle ; the cheeks, operculum, and body, covered with denticulated scales, 246 PLEURONECTID.E. which in shape, when detached, are longest in their vertical diameter. The colour of the body, is a reddish brown, mottled and spotted with very dark brown or black ; a large, conspicuous dark spot behind, but above the ends of the pectoral fin-rays ; the lateral line curved over the pectoral fin, then descending and intersecting the lower portion of the large dark spot, afterwards passing straight to the tail ; the fins paler brown than the body ; all the rays of the dorsal and anal fins with a line or row of denticulated scales along their upper surface ; the under side of the body smooth and white.

BY an oversight, the use of a looking-glass was omitted when making the drawing of this fish on the wood from the specimen, and the figure therefore appears with the eyes and the colours on the right side, like a Platessa, instead of on the left, as in a true Rhombus. The fish ought to have been represented with the head placed in the same di- rection as in the species last described. The Pleuronectes punctatus of Bloch, or, as it is here called to preserve the appropriation, Bloch's Topknot, is 248 PLEURONEOTID.E. much more rare than the Topknot of Muller ; but appears, like it, to have an extended range. Professor Nilsson in- cludes but one species in his Fishes of Scandinavia, but brings together the trivial names of the hirtus of Muller and the punctatus of Bloch. Dr. Fleming procured the true punctatus in Zetland, where, according to the testimony of the fishermen, it is not uncommon. Professor Henslow obtained at Weymouth the specimen from which Mr. Jenyns' description and the figure here inserted were taken ; and a comparison of the figures and descriptions referred to under the present fish with those of the Rhombus unimaculatus of M. Risso, in his Histoire Naturelle, will convince the observer that they are intended for the same fish. Bloch, if he has correctly figured his species, was, I think, mistaken in supposing his fish to be the same as Le Gros Plie ou Targeur of Duhamel ; as the separation between the ventral and the anal fins, and the want of con- nexion between the ends of both dorsal and anal fins with the tail, will demonstrate on comparing the two figures : but the character and disposition of the spots are something like those of Mullens fish. The figure by Dr. Fleming, in his Philosophy of Zoology, wants only the greater elon- gation of the first ray of the dorsal fin, perhaps a sexual dis- tinction, to render it identical with the figure here given, and that by M. Risso. I avail myself, by permission, of the very full description of this fish given by Mr. Jenyns in his Manual, taken from the specimen in the collection of the Philosophical Society of Cambridge.

THE WHIFF appears to have been first described and figured by Ray from Mr. Jago's Catalogue of Cornish Fishes, which is introduced, with short notices and representations, in Hay's Synopsis. This fish seems to occur more frequently in Cornwall than on any other part of our coast. Mr. Couch says, u This species is well known to the Cornish fishermen, who apply the name of Carter to it. It keeps on sandy ground, at no great distance from land, and takes a bait, so that it is caught as often as any of the salt-water Flatfishes ; but it is not highly esteemed for the table, chief- ly from being so thin." PLEURONECTID.E. Mr. Donovan found it in Wales ; Colonel Montagu ob- tained two on the Devonshire coast ; and Mr. Jenyns has described it in his valuable Manual of the British Vertebrate Animals, from a specimen obtained by Professor Henslow at Weymouth. Most of the specimens recorded measured from eighteen to twenty-one inches in length. But few particulars are known of this fish. It appears but seldom in the London market : I obtained one in June 1834 which measured seventeen inches in length, from which a representation and the following description are taken. The length of the head from the point of the upper jaw to the posterior edge of the operculum, compared to the length of the body alone, without the head or caudal rays, is as one to three ; the breadth of the body, dorsal and anal fins ex- cluded, is to the whole length of the fish rather less than one third : the dorsal fin commences half-way between the point of the nose and the anterior edge of the upper orbit, and ex- tends to within three-quarters of an inch of the end of the fleshy portion of the tail and the base of the caudal rays ; the pectoral fin on the under or white side is considerably smaller in size, and contains two rays less, than that on the upper side ; the ventral fins are of some extent at the base, as in the preceding species of the genus Rhombus ; the anal fin commences in a line under the origin of the pectoral fin, extends along the whole length of the abdominal line, and ends near the tail on the same plane as the dorsal fin ; the fleshy portion of the tail is narrow ; the caudal rays three inches long, and slightly rounded. The fin-rays in number are — D. 89 : P. 11 : V. 6 : A. 71 : C. 13. Vertebrae 41. The mouth is large ; the lower jaw the longest, with a rounded projection under the symphysis ; the teeth on both WHIFF. 253 jaws numerous, pointed and sharp : the eyes large ; the upper one the most so, and placed farther back than the lower ; the orbits separated by a prominent bony ridge : the lateral line conspicuous, elevated, and double over the pec- toral fin, one portion being a continuation of the prominent straight line along the body, the other rather less conspi- cuous, taking a high curve over the lower and the pectoral fin ; both lines ultimately approaching each other again at the upper angle of the operculum, as shown in the woodcut : the form of the body is an elongated oval ; the surface rough ; the scales rather large ; the colour a uniform yellow brown ; the fins rather lighter ; the under side smooth and white. A specimen in the British Museum exhibits faint indications of various spots, as shown in Mr. Donovan's coloured figure. 254 PLEURONECTID^E. SUBBRACHIAL MALACOPTERYCIL PLEURONECTID&. THE SCALDFISH.

THE SCALDFISH, or MEGRIM, as it is called in Corn- wall, appears, like the species last described, to be in this country, as far as we yet know, exclusively confined to the southern coast, and is only at present recorded as having been taken between Weymouth and the Land^s End. Mr. Couch says, " he has never known it take a bait, and its diminutive size prevents its being an object of attention to fishermen ; but they say it is much preyed upon by Con- gers and other large fishes, in the stomachs of which they often find it : it follows from this that it keeps in deep water." It seldom exceeds four or five inches in length ; but Mr. Couch has seen one that measured six inches and a half. M. Risso says the females are very prolific. SCALDFISH. 255 The length of the head is to that of the body as one to three, caudal rays excluded ; the depth of the body, without the dorsal or anal fins, equal to one-third of the whole length ; the dorsal fin commences over the upper eye, and reaches very nearly to the end of the fleshy portion of the tail; the pectoral fin long and narrow, but shorter and smaller on the under side ; ventral fins under the gill-cover ; the anal fin commencing in a line under the pectoral, and end- ing near the tail on the same plane as the dorsal fin ; caudal rays of moderate length, and slightly rounded ; but the rays of all the fins in both the specimens before me, from which the description is taken, extend considerably beyond the con- necting membranes of each, as shown in the woodcut. The fin-rays in number are — D. 87 : P. 6 : V. 10 : A. 60 : C. 18. The mouth is large, with small teeth in both jaws ; lower jaw the longest when separated : eyes rather large ; pupils blue ; irides yellow ; orbits separated by a bony ridge ; upper eye larger than the lower, and placed more backward in a vertical line : body in shape an elongated oval, narrowed towards the tail ; the scales large, round, thin, and trans- parent, almost all wanting, so easily are they removed on the slightest touch ; the body of the fish appears naked. I am indebted to the kindness of Mr. Couch for a Cornish speci- men : I also possess one from the Mediterranean, which enables me to say that our fish is the Rhombus nudus of M. Risso, as quoted. The lateral line after its commence- ment at the posterior edge of the operculum rises slightly over the pectoral fin ; then descending gradually, deviates but little from a straight line throughout the remainder of its course to the tail. The colour of both specimens is alike, a uniform pale yellow brown. 256 PLEURONECTID.E. SUBBRACHIAL MALACOPTERYGIL PLEURONECTID&. THE SOLE.

THE common Sole is so universally known as to require only a particular notice of those points in its economy that are the least obvious. It inhabits the sandy shore all round our coast, where it keeps close to the bottom, feeding on the smaller testaceous animals, and the spawn and fry of other fishes. It is taken among the Orkneys, and along the north- east coast ; but it is of small comparative size : the Soles of the south and west are much larger, and considered otherwise superior to those of the north and east. The Sole is found northward as far as the Baltic and the SOLE. seas of Scandinavia; and southward, along the shores of Spain, Portugal, and the Mediterranean. It was first described by Bellon. Soles — and of these an enormous quantity — are caught almost entirely by trawling ; they seldom take any bait. It is usual to send them to market in baskets, within which the Soles of small size, called Slips, are arranged nearest the wicker-work forming the outside of the basket : the larger Soles, being more valuable, are packed in the middle. Eighty-six thousand bushels of Soles were received at Bil- lingsgate market only within the last twelvemonths. The Sole is found full of roe at the latter end of Fe- bruary. They are then for a few weeks soft and watery ; but they soon recover, and throughout a great portion of the year are deservedly in high estimation : the flesh is white, firm, and of excellent flavour ; those from deep water are the finest in quality. The principal trawling-ground in England is along the south coast from Sussex to Devonshire : the Sole has also been taken on the shores of various counties in Ireland, viz. Cork, Waterford, Antrim, Londonderry, and Donegal. On the Devonshire coast there are two great fishing stations, Brixham and Torbay ; the boats from which, using large trawling-nets from thirty to thirty-six feet in beam, produce a continual supply. Soles of very large size are occasionally taken. I have a record of one pair taken in Torbay which measured twenty-three inches in length each, and weighed together ten pounds ; but for the particulars of the largest I have heard of, I am indebted to the kindness of the Rev. W. F. Cornish, of Totness. This specimen, a remarkably fine-grown fish, and very thick, was twenty-six inches long, eleven inches and a half wide, and weighed nine pounds. — Totness market, June 21st, 1826. 258 PLEURONECTID.E. Soles appear to thrive well in fresh water. Dr. M'Cul- loch, in his papers on " Changing the Residence of certain Fishes from salt water to fresh,"* says, he was informed that a Sole had been kept in a fresh-water pond in a garden for many years ; and adds, that in Mr. Arnold's pond at Guern- sey, which has been before referred to, the Sole becomes twice as thick as a fish of the same length from the sea. A letter from a gentleman residing on the banks of the Arun contains the following statement : — " I succeeded yesterday in seeing the person who caught the Soles about which you inquire, and who has been in the constant habit of trawling for them with a ten-feet beam trawl in this river for the last forty years. The season for taking them is from May till November. They breed in the river (Arun), frequenting it from the mouth five miles upwards,f which is nearly to the town of Arundel, and remain in it the whole year, bury- ing themselves in the sand during the cold months. The fisherman has occasionally taken them of large size, two pounds' weight each, but frequently of one pound ; and they are thicker in proportion than the Soles usually caught at sea. In other respects, precisely the same ; and it is evident they breed in great numbers in the river from the quantity of small ones about two inches long that are constantly brought on shore when drawing the net for Grey Mullet." Reversed Soles — that is, having the eyes and the brown colour on the left side instead of the right — are not uncom- mon : and I possess a specimen that is of the usual dark co- lour, with rough ciliated scales on both sides. The length of the head is to the whole length of the entire fish as one to six ; the breadth of the body, dorsal and anal * Royal Institution Quarterly Journal, No. xxxiv. July 1824, and No. xxxviii.

SOLE. 259 fins excluded, compared to the whole length, as one to three: the nose is rounded and produced, projecting beyond the mouth : the upper jaw the longest ; both jaws furnished with minute teeth on the under or white side of the fish only : the eyes small ; the lower eye over the angle of the mouth ; the upper eye placed more forward in a vertical line ; the irides yellow ; the pupils blue : the space between the eyes, the cheek, and operculum, flat, and covered with small rough ciliated scales : the pectoral and ventral fins small ; the dorsal fin begins at the point of the nose, the anal fin under the line of the edge of the gill-cover ; both extend the whole length of the body, ending on the same plane, near the base of the caudal rays ; and both these fins have a series of small, rough, ciliated scales, extending along the line of each ray : the tail rather long, and slightly rounded. The fin-rays in number are — D. 84 : P. 7 : V. 5 : A. 67 : C. 17. Vertebra 47. The form of the body is a long oval, widest at a short distance behind the head, becoming narrower and rather pointed towards the tail ; the colour on the upper side al- most a uniform dark brown ; the scales small, each ciliated at the edge, and rough to the touch ; the lateral line running straight from the tail forward to the operculum, then rising and ending on a line with the superior edge of the upper orbit ; the pectoral fin tipped with black. On the under side the colour is white : about the nostril and mouth are numerous soft papillae. 260 FLEURONECTID.E. SUBBRACHIAL MALACOPTERYGII. PLEURONECTW&. THE LEMON SOLE.

DURING a short visit to Brighton in the last week of February 1829, I obtained a single example of this species of Sole, which appeared to have been previously unnoticed as occurring on our shores. Since it was described in the Zoological Journal, as above quoted, I have obtained, but at considerable intervals, two or three other specimens of this fish in the London market, and have now deposited exam- ples in the British Museum and the collection of the Zoolo- gical Society. This species is occasionally taken with the common Sole when trawling over a clear bottom of soft sand, about sixteen miles from Brighton in a direction towards the coast of France; from which circumstance this fish is known to some of our fishermen by the name of French Sole ; others call it LEMON SOLE. by that of Lemon Sole, in reference to its prevailing yellow- ish colour. In shape the Lemon Sole is wider in proportion to its whole length than the common Sole, and it is also somewhat thicker; the head is smaller, being in proportion to the whole length of the fish rather less than as one to seven ; the breadth of the body, dorsal and anal fins included, exactly half the whole length : the arrangement of the fins is nearly the same as in the common Sole ; but the fin-rays and the number of vertebrae differ. D. 81 : P. 8 : V. 5 : A. 69 : C. 17. Vertebra 43. The prevailing colour is a mixture of orange and light brown, freckled over with numerous small round spots of dark nutmeg brown, giving a mottled appearance to the whole upper surface. The scales differ in character; the lateral line is straight, but not so prominent or strongly marked; the tail is narrower than in the common Sole, though containing the same number of rays ; the end of the pectoral fin spotted with black. On the under side the ap- pearance is still more characteristic of the distinction of the species. The under surface of the head is almost smooth, without any of the papillary eminences so numerous and remarkable in the common Sole, and the nostril is pierced in a prominent tubular projection, which is wanting in the other : the under surface is white, with the appearance of the scales more strongly marked than upon the upper.

THE VARIEGATED SOLE appears, like the Lemon Sole last described, to be a rare species, and but few specimens are to be found in collections, though it seems to have a wide range. According to Professor Reinhardt, it is found on the shores of Scandinavia. In the Magazine of Natural History, conducted by Mr. Loudon, a notice appears, vol. vi. page 530, that it has been taken at Rothsay. Mr. Dono- van obtained one seven inches long in the London market ; and Mr. Jenyns has described this fish in his Manual from a VARIEGATED SOLE. 263 specimen procured at Weymouth. Colonel Montagu men- tions that Dr. Leach bought three in Plymouth market in August 1808, and gave him one of them, measuring nine inches in length, from which his notes of the species were recorded in his MS.; and Mr. Couch has observed it in Corn- wall, very kindly sending me a specimen, from which the woodcut was executed. But little is known of the habits of this species ; but it is stated in Pennant that it appears about Plymouth in the spring. It is immediately distinguished from either of the Soles previously described here, by its variegated colour ; by its scales, which are larger ; by its pectoral fins, which are much smaller, that on the under side being very minute ; and by the dorsal and anal fins, as shown in the cut, ending consi- derably short of the tail. The whole length of the specimen described was five inches ; the breadth without the fins, one inch and three- eighths ; the length of the head compared to that of the body alone, as one to four : the dorsal and anal fins ending on the same plane, but not reaching the base of the caudal rays, and both having the numerous rays projecting beyond the edges of the connecting membranes, as shown in the cut ; the right pectoral fin small, that on the under side consisting of only two unequal, slender, and short rays. The fin-rays in number are — D. 67 : P. right side 4 : left side 2 : V. 5 : A. 52 : C. 16. The body is thicker in proportion than either of the Soles previously described ; the scales larger, the divisions strong- ly marked, the edges ciliated, rough to the touch ; the lateral line straight : the colour of the upper side reddish brown, clouded both on the body and fins with darker brown ; the under surface white ; scales also ciliated and harsh to the touch. 264 CYCLOPTERIDA:.

BARON CUVIER has called the third family of the Sub- brachial Malacopterygii, Discoboles, on account of the disk formed by the union of the ventral fins.

CORNISH SUCKER. 265 the families. The pectoral fins in these fishes are large, descending to the inferior surface of the body, where they are joined by four strong rays, and, united by a membrane to a similar structure on the opposite side, form the boundary of an adhesive disk. In the species of the first genus, a second disk is formed by the union of the ventral fins. The few species belonging to this small family are very remarkable for the power they possess of attaching them- selves to stones, rocks, or other substances, by means of the adhesive apparatus on the under surface of their bodies, ap- parently deriving some degree of protection and support from the contact. The two British species belonging to the first genus are small, defenceless, their bodies smooth, without scales ; and the power of attaching themselves to stones, &c. which they are seen to exercise, may be useful by enabling them to resist the action of strong currents or dashing waves, and is perhaps applicable with them to other uses, with which naturalists are not yet acquainted. The first prettily-marked species of Sucking-fish was dis- covered by Dr. Borlase, who found it on the coast of Corn- wall, and described it under the name of the Lesser-Sucking- fish, in his Natural History of that county. Pennant afterwards found it at Jura, in the Hebrides, and called it in consequence the Jura Sucker ; but if any name indicative of a peculiar geographical locality is admissible, it ought to have been that only in which it was first discovered ; and I have therefore followed Dr. Fleming and Mr. Jenyns in calling it the Cornish Sucker, although this name is not entirely free from objection, two other species of fishes, provided with suckers, being found in Cornwall. Mr. Couch says, however, that this fish is there called pre-eminently the Sucking-fish by fisher- men, from the readiness with which it adheres to any substance, VOL. II. T 266 CYCLOPTERID.E. and even to the hand that seizes it, — a circumstance which has also been noticed by Colonel Montagu. " It is sluggish in its habits ; but seems to wander, since it is sometimes abundant, and at others rare. Its usual haunts are about low-water mark, where it is often left by the tide, concealed beneath a stone. I find it," says Mr. Couch, " large with spawn in March. Its food is crustaceous animals and marine insects, which it swallows entire." The whole length of the specimen described was two inches and a half ; the distance from the point of the nose to the end of the gill-cover was equal to one-third of the whole length of the fish : the head depressed ; mouth pro- duced ; very much flattened ; narrower than the head ; has been aptly called spatula-like ; gape elongated : numerous small teeth in both jaws, forming a band in each : under surface of the head very flat ; the first disk before the line of the opening of the gill-cover ; the second disk behind it : upper surface of the head smooth ; before the inner corner of each eye a small flattened filament, about equal in length to the diameter of the eye itself; behind this a second, but much shorter ; both of a bright carmine colour ; behind the eyes, which are widely separated, are two distinct, red, eye- like spots : the dorsal fin commences about half-way between the eyes and the end of the tail ; the anal fin begins still nearer the tail, and both are joined to it by a membrane ; the tail rounded ; the posterior part of the body compressed. The pectoral fin large, with an extension underneath of four stronger rays, which with the connecting membrane form the sides of the most anterior disk of the two ; an extension of the membrane only, without rays, being continued along the front. Immediately behind the broad swimming portion of the pectoral fin on each side, a membrane arises in the same vertical position, which joining the united ventral fins forms CORNISH SUCKER. £67 the free edge of the second disk, the rays of the two ventrals occupying the posterior portion, and the continuation of the connecting membrane making the circle entire. The fin-rays in number are — D. 18 : P. 19 : A. 10 : C. 18. The general tint a pale flesh colour with spots and patches of carmine about the upper and under surface of the jaws, around the eyes, on the top of the head, sides of the body and abdomen. The description was taken from the largest of five specimens, on three of which the spots behind the eyes were conspicuous, but wanting in the other two. The appearance of the surface of the disk is shown in the woodcuts of some of the more closely allied species, to assist in determining specific distinction. The vignette below represents a man fishing for prawns on a rocky coast. The fisherman deposits around him eight or ten hoop-nets, each baited with a piece of stale fish : a large bung by way of a buoy is attached to each hoop. The man, with a long forked stick raises the nets in succession, by putting the fork of the stick under the bung, and deposits them again after examination. CYCLOPTERIDJE.

THIS very distinct species was first described by Pennant from a specimen sent him by the Duchess of Portland, which was taken at Weymouth. It has since been taken by Mr. Donovan on the coast of Kent ; by Professor Henslow at Weymouth ; by Colonel Montagu in Devonshire, and at two different localities in Cornwall, Polperro and Penzance. It has also been taken by Mr. William Thompson of Bel- fast, when dredging for shells on the coast of the county of Down in Ireland. Colonel Montagu obtained it by deep dredging at Tor- cross, adhering to stones and old shells, and kept some spe- cimens alive for a day or two in a glass of sea-water. BIMACULATED SUCKER. 269 " In this situation they always adhered to the sides of the glass by the apparatus termed the sucker, and frequently remained fixed till they died ; and even after death the power of adhesion continues ; the wet finger being applied to the part, the fish becomes suspended : when alive they instantly attach themselves to the hand if taken out of the water." Mr. Couch says it keeps in deeper water than the prece- ding species ; but is occasionally found under stones at low- water mark. In this species, of which I possess several examples, varying in length from three-quarters of an inch to one inch and three- quarters in length, the head is depressed ; the posterior por- tion of the body compressed ; the head is shorter, compared to the whole length, than in the preceding species : the mouth wider ; but the jaws not so much produced ; the teeth similar ; no filaments before the eyes ; the irides pink and gold ; the pupils blue : the additional rays at the inferior part of the pectoral fin, and the connecting membrane on each side, making up the lateral portions of the anterior disk, are much longer : the ventral fins form the sides of the second or posterior disk, and are also elongated ; the dorsal and anal fins of equal size, opposite, short, placed far back ; commenc- ing and ending on the same planes : not connected with the tail, between which and the two fins just named there is a considerable space : tail rather elongated. The fin-rays in number are — D. 6 : P. 19 : A. 6 : C. 10. The general colour carmine red ; pale flesh colour under- neath, with a light-coloured patch between the eyes, and otherwise liable to some variation in the markings ; the two spots on the sides not always very obvious ; young specimens are without these lateral markings. 270 CYCLOPTERID.E.

THE LUMP SUCK KB is remarkable for its very grotesque form, while from the large size of its body, both as to depth and thickness in reference to its length, and the compara- tively small size of its fins, it appears calculated to make but slow progress through the water LUMP SUCKER. It is more plentiful northward than on our southern coast, and beyond this country has a most extensive range. Pen- nant includes it in his Arctic Zoology. It is caught on the coast of Greenland, where it is eaten. Professors Nilsson and Reinhardt include it among the fishes of Scandinavia; and Mr. Low considers it common in the Orkneys. Dr. Neill says that in the spring months it is caught on the sands of Porto- bello, and sent for sale to the Edinburgh market, where it is purchased for table, and the male fish considered superior to the female. Along our eastern and southern coasts it is also taken more exclusively during spring, when it approaches the shore for the purpose of depositing its spawn, which happens in April or the beginning of May. This species has also been taken at Belfast ; and the Lump Sucker of the North American shores is apparently identical with our own. Some of our fishermen consider that we have on our coast two species of Lump-fish, which they distinguish by the names of Red-Lump and Blue-Lump, considering the first only as eatable ; but the difference in colour, and also in the quality of the flesh, is only the effect of season ; the fine ex- ternal colour, as well as the firmness of the flesh, being lost to the fish for a time by the exhausting process of spawning ; it is then by them considered as the worthless Blue-Lump. The ova forming the hard roe are of large size, and of a fine orange colour. The young are four inches and a half long, and three inches in height, by the end of November. Shaw's specimen, of six inches in length, to which he attached the specific name of Pavonina, is only a young fish of our com- mon species, which for want of sufficient age had not attained its perfect colour. As the Lump-fish is retentive of life, its power of adhesion is sometimes made the subject of experi- ment. Pennant says, " That on placing a fish of this spe- cies, just caught, into a pail of water, it fixed itself so firmly CYCLOPTERIDJE. to the bottom, that on taking it by the tail, the whole pail by that means was lifted, though it held some gallons, and that without removing the fish from its hold." The Lump-Sucker feeds principally on young fish, of which it devours a large quantity. Mr. Couch says that it sometimes takes a bait, and he has found in its stomach various onisci. In the month of March the colours of the Lump-fish are in the highest perfection, combining various shades of blue, purple, and rich orange ; it is then frequently to be seen in the shops of London fishmongers, suspended by the middle of the back, attracting attention from the combination of singular form and brilliant colours. A specimen sixteen inches long is usually about eight inches deep, and four inches wide : the length of the head is about one-fourth of the whole length of the fish ; the descend- ing line of the profile of the head is abrupt ; the back highly arched and somewhat compressed, forming a ridge, with a row of tubercles along the upper edge ; on cutting through the integument, the ridge is found to be supported by several rays, which sometimes from abrasion of the hard skin appear externally, and have been considered as bearing some resem- blance to an anterior dorsal fin. Behind this central ridge, and over the last third portion of the curve of the dorsal line, is the true dorsal fin, the length of the base of which is about equal to the length of the longest of its rays ; the pectoral fins descend low on the sides, and passing forwards enclose the adhesive apparatus which extends anteriorly to the edge of the membrane connecting the branchiostegous rays, and backwards as far in a vertical line as the posterior angle of the operculum : the union of the ventral fins complete the single disk of the only species of this genus that inhabits our LUMP SUCKER. 273 seas. The anal fin is under or opposed to the dorsal, and of nearly the same size and shape : the tail moderate. The fin-rays in number are — D. 11 : P. 20 : A. 9 : C. 10. Each of the rays with a row of hard tubercles along a con- siderable portion of their length. The whole surface of the head and body is covered with small bony tubercles, most of which are more or less stellated in form. Along several parts of the body are rows of larger and more prominent tubercles, with surfaces minutely granulated ; one row occupies the cen- tral ridge of a portion of the back ; two or three tubercles are placed on each side just in advance of the dorsal fin ; one long row extends from the upper angle of the operculum in a straight line to the upper part of the end of the fleshy por- tion of the tail ; a second long row reaches from the space above the pectoral fin to the lower part of the fleshy portion of the tail ; another row of large size extends along the ab- domen on each side as far as the commencement of the anal fin. The mouth is wide ; the lips fleshy; the lower jaw the longest : a band of short and small teeth in each jaw ; a small patch of rounded teeth on the root of the tongue, with others at the pharynx : the irides a fine red ; the colour of the sides of the head and body, and all the upper parts, varying shades of dark blue, lighter blue, and purple ; the lips, under surface of the head and body, fine rich orange ; all the fins tinged with the same colour. After the season of spawning is over, much of the brilliant colouring is lost for a time. CYCLOFTERJIhE. SUBBRACHIAL MALACOPTERYG1I. CYCLOPTERIDM. THE UNCTUOUS SUCKER, OR, SEA-SNAIL.

THE UNCTUOUS SUCKER, or SEA-SNAIL, so called from the soft and slimy surface of its body, appears to be much more common in the northern parts of the British Islands than in the southern. Mr. Scoresby, and other observers, have even found it as far north as Greenland ; and specimens of it were taken in the trawl-net on the west coast of Da vis's Straights during the first Arctic voyage of Captain Sir Ed- ward Parry ; yet it does not appear to be mentioned by Pro- fessor Nilsson or Beinhardt in their accounts of the fishes of the Scandinavian shores ; nor is it included by Linnseus in his Fauna Suecica, UNCTUOUS SUCKER. 275 Mr. Low says, " The Sea-Snail is found under the stones of many places of Orkney ; but no place more frequent than that at the point of the Ness of Stromness, where they may be picked up by dozens." Mr. Donovan obtained a specimen from among a parcel of Sprats at Billingsgate fish-market ; and those who recollect the wholesale mode of fishing for Sprats practised by the Stow-boatmen, as described at page 123, will not be sur- prised that many rare and curious fishes of small size are caught with the Sprats. It is also obtained on the southern coast, under stones, and in small pools of water left by the ebbing tide. Dr. Mac Culloch says this species ascends rivers from the sea to deposit its spawn, and it is frequently found near the mouths of rivers. Pennant says it is full of spawn in January, and the matured ova are said to be very large. It feeds on aquatic insects, testaceous animals, and very small fishes. The whole length of the specimen described was four inches, which is the common size of the adult of this species ; but it is said to grow much larger in the Northern Seas : the head is about one-fourth of the whole length of the fish ; the eyes widely separated, the space between them depressed ; the nose blunt ; the lips thick and fleshy ; the mouth wide, but not deeply divided. Mr. Low says it has no teeth ; but this is an oversight ; the teeth are very numerous, and small, with minutely recurved points, forming a broad rasp-like band in each jaw ; the tongue also broad, covered with pro- minent papillae ; the lower jaw rather the longest ; the gill- opening placed high up ; the form from the shoulder is compressed, and tapering all the way to the tail ; the body invested with a thin semi-transparent membrane, which en- closes it like a bag, the fixed points being the lines of the dorsal and anal fins ; the pectoral fins are large, and the £76 CYCLOPTERID.E. lower portions descending the side are attached to additional rays like ventral fins, which extending far forward are situ- ated exterior to the sides of the adhesive disk ; the belly tumid ; the dorsal fin begins much nearer the head than the anal fin, and both end close to the tail ; the caudal rays ra- ther long and narrow. The fin-rays in number are — D. 36 : P. & V. 32 : A. 26 : C. 12. The colour of the body is a pale brown, irregularly striped with lines of a darker colour, which take different directions, and give a variegated appearance to the head, back, and sides ; these lines are confined to the outer thin skin, and do not appear upon the more solid surface underneath ; in this state some authors have called this species lineatus ; but these markings are not constant, and many examples are without any streaks or lines, the edges of the dorsal and anal fins only being edged with a darker colour ; the tail, and sometimes the pectoral fins, slightly barred and spotted. When kept in diluted spirit of wine, the coloured lines and characters of the species may be easily preserved ; but this fish loses both markings and size if allowed to become dry.

A drawing of it was sent by that excellent observer to Mr. Donovan, who was then publishing his Natural History of British Fishes, and with whom the specific name, referring to Colonel Montagu, originated. The first specimen obtained was of very diminutive size. Subsequently Colonel Montagu having acquired various other larger and adult specimens, published a description and figure of this species himself in the Memoirs of the Wernerian Natural History Society, as already quoted. 278 CYCLOPTERID^J. This fish has since that period been found on various parts of the coast. Dr. George Johnston has obtained it in Ber- wick Bay ; Mr. Thompson has taken it in Belfast Bay ; and it is not uncommon in Cornwall, as well as on the Devonshire coast. Colonel Montagu says this species inhabits only the rocky parts of the coast, and of course is rarely taken with the dredge. Those obtained by its discoverer were found at exceedingly low tides among the rocks at Milton, on the south coast of Devon. When it is adhering to a rock the posterior part of the body is frequently turned to one side, nearly parallel with the anterior part, the tail being brought close to the head. This habit of curving its body has been observed by all those who have found this species. Mr. Couch's notice of it in his MS. is as follows: — " This is a common species in the West of England, where, how- ever, it seems to wander, since at certain times it is much more rare than at others. It possesses considerable activity ; and when the tide has ebbed it is often found concealed be- neath a stone, where when at rest it usually throws the tail forwards towards the head. I have never seen it adhere to any fixed substance. The young come to life in September." Montagu's Sucker, in the adult state, is from two inches and a half to three inches long : the body is rounded as far as the vent ; the posterior end somewhat compressed ; head broad, a little depressed, and inflated about the gills ; mouth moderately large ; both jaws armed with several rows of mi- nute teeth : eyes small, and placed high ; irides golden ; pupils dark blue, with a single blue line descending from the eye to the angle of the mouth : the operculum angular ; the branchiostegous membrane transparent ; the pectoral and ventral fins unite ; the first is rounded ; in the last, four or five rays on each side invest the adhesive disk, which is sin- MONTAGU S SUCKING-FISH. £79 gle, small, and circular : an enlarged representation of the Sucker is here added to assist in affording the means of determining the species : the belly is very tumid ; the vent far removed behind the sucker. The dorsal fin commences farther from the head than in the last species ; the most an- terior rays short, but gradually increasing in length form a broad fin towards the tail, where it is rounded : the anal fin shorter than the dorsal. The fin-rays in number are — D. 26 : P. & V. 29 : A. 24 : C. 12. This description is partly obtained from Montagu's paper. The prevailing colour is a dull orange, varied with occa- sional bluish tints ; the fins brighter orange red ; the lateral line perceptible by a lighter-coloured streak ; the under parts of the body, and about the throat and sucker, white, tinged with flesh colour. 280 ECHENEID.E.

DR. TURTON in his British Fauna includes this species of Sucking-fish, having taken a specimen himself at Swansea from the back of a Codfish in the summer of 1806. The species of this singular family are not numerous : Cuvier enumerates but four that are as yet made known, and another large West Indian one has been more recently de- scribed. They are immediately recognized by the flattened, COMMON REMORA. 281 oval, adhesive disk, on the top of the head, by means of which they are able to attach themselves firmly to the sur- face of other fishes, or the bottoms of vessels ; but whether for protection or conveyance, or both, is a question which has not been satisfactorily ascertained. The Greeks and Romans were well acquainted with the Mediterranean species, which is the fish under present con- sideration. The length of the head, from the end of the upper jaw, which is much the shortest, to the end of the operculum, is nearly one-fifth of the whole length of the fish ; the depth of the body about one-seventh of the whole length : the form of the head is flattened, very much depressed ; the body about the middle nearly round in form, the posterior half compressed : the mouth is wide ; the opening nearly horizontal, with two bands of minute teeth in the elongated lower jaw, a single band on the upper jaw, with others on the tongue and vomer, all curving inwards : the eye placed about half-way between the point of the upper jaw and the rounded end of the operculum ; the gill-aperture very large ; the adhesive disk in this species contains seventeen or eigh- teen transverse laminae, divided by a longitudinal mesial ridge ; the disk commences just behind and above the upper lip, and extends nearly as far back as the line of the ends of the pectoral fin-rays : all the fins are covered with a dense membrane, which imparts to them the consistence of leather ; the pectoral fins are rather small and rounded ; the ventrals narrow, very close together, the inner ray of each attached to the central line of the belly by a membrane ; the dorsal and anal fins are both placed behind the mid-length of the fish, beginning and ending on the same plane ; the end of the caudal rays crescent -shaped. VOL. II. U ECHENEID.E. The fin-rays in number are — D. 21 : P. 22 : V. 4 : A. 20 : C. 20. The colour is dusky brown ; the under part of the body rather lighter than the back ; the fins darker in colour than the body. The disk of the adhesive apparatus in the specimen now described with seventeen transverse laminae was one-third of the whole length of the fish, not including the caudal rays ; the breadth one inch and one quarter. The figure on the left side of the vignette represents the outer surface of the anterior half of the disk : the margin is free, flexible, and of considerable breadth, to secure perfect contact with the surface to which it is opposed ; the parallel laminae are represented as only slightly elevated ; the degree of adhesion is in proportion to the power used to raise the inner surface of the disk in a direction perpendicular to the plane of con- tact. The figure on the right side of the vignette represents the inner surface of the posterior half of the disk. The ver- tical direction of the moveable laminae is effected by sets of muscles going off obliquely right and left from two elon- gated bony processes, one on each half of each of these move- able divisions. The contraction of these muscles, acting upon these levers, raises the external edges of the parallel divisions, increasing the area of the vacuum ; and it will be observed that the points of the moveable transverse divisions to which the muscles are attached are nearer the middle line than the outer edge, by which the chance of interfering with the perfect continuity of the free margin, and thereby de- stroying the vacuum, is diminished. All the bony laminae, the outer edges of which are furnished with rows of minute tooth-like projections, are moved simultaneously, like the COMMON REMOKA. thin vertical divisions of our common wooden window-blinds by means of the mechanical contrivance on the frame- work. The longer muscles placed nearer the outer oval edge are probably instrumental in preserving the contact of the more flexible margin, and the serrated external edges of the parallel laminae help to preserve the degree of elevation ob- tained : the adhesive power is in proportion to the area of the vacuum. 284 MURjENIDJE.

BARON CUVIER, in this family of the Muranida, or Eel- shaped Fishes, which includes several genera forming his fourth order, has brought together those fishes with soft fins which have an elongated form of body : they are also destitute of ventral fins, and are in consequence called Apo- dal. The genus Anguilla, including our common Eels, is the first of this order. SHARP-NOSED EEL. 285 The general appearance of the Eel is so well known, and so unlike that of most other fishes, as to require but a slight description ; yet it was not till a period of very modern date that naturalists became acquainted with the fact that the fresh waters of several countries produce three or four dis- tinct species which had previously been confounded together. Thus the first edition of the Regne Animal, published in 1817, included but one species of common fresh-water Eel as well known : the second edition, published in 1829, con- tains a short notice of four different species ; three of which, if not all four, are found in this country. The form of the Eel, resembling that of the serpent, has long excited a prejudice against it, which exists in some countries even to the present time ; and its similarity to snakes has even been repeated by those, who, from the advantages of education, and their acquirements in natural history, might have been supposed capable of drawing more accurate con- clusions. There is but little similarity in the snake and the Eel except in the external form of the body : the important internal organs of the two animals, and the character of the skeleton, are most decidedly different. Eels are in reality a valuable description of fish : their flesh is excellent as food ; they are very numerous, very prolific, and are found in almost every part of the world. The various species are hardy, tenacious of life, and very easily preserved. In this country they inhabit almost all our rivers, lakes, and ponds ; they are in great esteem for the table, and the con- sumption in our large cities is very considerable. The Lon- don market is principally supplied from Holland by Dutch fishermen. There are two companies in Holland, having five vessels each : their vessels are built with a capacious well, in which large quantities of Eels are preserved alive till wanted. One or more of these vessels may be constantly 286 MUR.ENID.E. seen lying off Billingsgate ; the others go to Holland for fresh supplies, each bringing a cargo of 15,000 to 20,000 pounds' weight of live Eels, for which the Dutch merchant pays a duty of IS/, per cargo for his permission to sell. Eels and Salmon are the only fish sold by the pound weight in the London market. Eels are not only numerous, but they are also in great request, in many other countries. Ellis, in his Polynesian Researches, vol. ii. page 286, says : " In Otaheite, Eels are great favourites, and are tamed and fed until they attain an enormous size. These pets are kept in large holes, two or three feet deep, partially filled with water. On the sides of these pits they generally remained, excepting when called by the person who fed them. I have been several times with the young chief, when he has sat down by the side of the hole, and, by giving a shrill sort of whistle, has brought out an enormous Eel, which has moved about the surface of the water, and eaten with confidence out of its master's hand." a Most of the writers on the habits of the Eel have de- scribed them as making two migrations in each year : one in the autumn to the sea ; the other in spring, or at the begin- ning of summer, from the sea. The autumn migration is performed by adult Eels, and is believed to be for the pur- pose of depositing their spawn ; it is also said that these parent fish never return up the rivers. The spring migration is commonly supposed to be confined to very small Eels, not more than three inches in length, and in reference to the fry alone, it is too well known, and too often recorded, to be matter of doubt. The passage of countless hundreds of young Eels has been seen and described as occurring in the Thames,* the Severn, the Parrett, the Dee, and the Ban. * See an excellent account by Dr. William Roots, of Kingston, published in the second series of Gleanings in Natural History, by Edward Jesse, Esq. p. 50. SHAIIP-NOSED EEL. 287 I am, however, of opinion, that the passage of adult Eels to the sea, or rather to the brackish water of the estuary, is an exercise of choice, and not a matter of necessity ; and that the parent Eels return up the river as well as the fry." " All authors agree that Eels are extremely averse to cold. There are no Eels in the arctic regions, — none in the rivers of Siberia, the Wolga, the Danube, or any of its tributary streams ; yet the rivers of the southern parts of Europe produce four species. There is no doubt that fishes in general, and Eels in particular, are able to appreciate even minute alterations in the temperature of the water they inhabit. The mixed water they seek to remain in during the colder months of the year is of a higher temperature than the pure fresh water of the river, or that of the sea. It is a well-known law in chemistry, that when two fluids of dif- ferent densities come in contact, the temperature of the mix- ture is elevated for a time in proportion to the difference in density of the two fluids, from the mutual penetration and condensation. Such a mixture is constantly taking place at the mouths of rivers that run into the sea, and the mixed water maintains a temperature two degrees warmer than that of the river or the sea. This elevation in the temperature of the water of estuaries and the mouths of rivers is, I have no doubt, one reason why they in general abound in young fish." In a tideway river the descent of the Eels towards the brackish water takes place during the autumn, and various devices are employed in different streams to intercept them in their progress. The vignette at the bottom of the next page represents the form of an apparatus used in various parts of the Thames, called an Eelbuck, consisting of a framework of wood supporting various wicker-baskets of a particular form. The large open end of each basket is opposed to the stream, and by the peculiar structure of the inside, any fish once within the body of the basket, cannot escape. 288 MUR^NID.E. During the cold months of the year Eels remain imbedded in mud ; and large quantities are frequently taken by Eel- spears in the soft soils of harbours and banks of rivers, from which the tide recedes, and leaves tne surface exposed for several hours every day. The Eels bury themselves twelve or sixteen inches deep, near the edge of the navigable chan- nel, and generally near some of the many land-drains, the water of which continues to run in its course over the mud into the channel during the whole time the tide is out. In Somersetshire the people know how to find the holes in the banks of rivers in which Eels are laid up, by the hoar-frost not lying over them as it does elsewhere, and dig them out in heaps. The practice of searching for Eels in mud in cold weather is not confined to this country ; Dr. Mitchill, in his paper on the Fishes of New York, published in the Transactions of the Literary and Philosophical Society of that city, says, " In the winter Eels lie concealed in the mud, and are taken in great numbers by spears." Thus SHARP-NOSED EEL. 289 imbedded in mud, in a state of torpidity, the Eel indicates a low degree of respiration. Dr. Marshall Hall has shown that the quantity of respiration is inversely as the degree of irritability. With a high degree of irritability and a low respiration, co-exist — 1st. The power of sustaining the pri- vation of air and of food ; 2nd. A low animal temperature ; 3rd. Little activity ; 4th. Great tenacity of life. All these peculiarities Eels are well known to possess. The high de- gree of irritability of the muscular fibre explains the restless motions of Eels during thunder-storms, and helps to account for the enormous captures made in some rivers by the use of gratings, boxes, and Eel pots or baskets, which imprison all that enter. The power of enduring the effects of a low tem- perature is shown by the fact, that Eels exposed on the ground till frozen, then buried in snow, and at the end of four days put into water, and so thawed slowly, discovered gradually signs of life, and soon perfectly recovered. The mode by which young Eels are produced appears to have long been a subject of inquiry, and the notions of the ancients as well as of some of the moderns were numerous and fanciful. Aristotle believed that they sprang from the mud ; Pliny, from fragments which were separated from their bodies by rubbing against rocks ; others supposed that they proceeded from the carcases of animals; Helmont believed that they came from May-dew, and might be obtained by the following process : — u Cut up two turfs covered with May- dew, and lay one upon the other, the grassy sides inwards, and thus expose them to the heat of the sun ; in a few hours there will spring from them an infinite quantity of Eels." Horse-hair from the tail of a stallion, when deposited in water, was formerly believed to be a never-failing source of a supply of young Eels. It was long considered certain that they were viviparous : this belief had its origin probably in the MUR^NID.E. numerous worms that are frequently to be found in various parts of the bodies of Eels, sometimes in the serous cavities, at others in the intestinal canal. Rudolphi has enumerated eight different species of entozoa common to fresh- water Eels. The enormous number of young known to be produced by Eels is a good negative proof that they are oviparous ; vivi- parous fishes producing, on the contrary, but few young at a time, and these too of considerable size when first excluded. Having devoted time and attention to the close examination of numbers of Eels for many months in succession, the fur- ther details of which will be found in Mr. Jesse's second series of Gleanings in Natural History, I need only here repeat my belief that Eels are oviparous, producing their young like other true bony fishes. " The sexual organ consists of two long narrow sacs ex- tending one on each side of the air-bladder throughout the whole length of the abdominal cavity, and continued for two inches posterior to the vent. The membranes forming this tubular sac, secreting on the inner surface the milt of the male, and affording attachment for the ova in the female, are puckered or gathered along the line of junction to the peri- toneal covering of the spine, and the free or loose floating edge is therefore thrown into creases or plaits like a frill. It is probably from this folded or convoluted appearance the sexual organs of the Eel have frequently been called fringes. By the kindness of my friends Mr. Clift and Mr. Owen, of the Royal College of Surgeons, I have had the pleasure of seeing some drawings belonging to the collection of John Hunter, in which these peculiarities of the sexual organs in the Eel are beautifully exhibited in various magnified repre- sentations." Dr. Mitchill of New York, whose paper on Fishes has been already referred to, says, " the roes or ovaria of Eels may SHARP-NOSED EEL. 291 be seen by those who will look for them in the proper season, like those of other fishes." Eels that have lain in brackish water all the winter under the constant influence of the higher temperature of that locality, probably deposit their spawn earlier in the spring than those which have passed the winter in places from which there existed for them no possible egress. In the Mole, the Wey, the Longford river, and in some large ponds, the Eels in the spring of 1833 did not deposit their spawn till near the end of April ; but in two Eels from Sheerness received and examined on the 18th of May, the internal appearances induced me to believe that the roes had been passed some time. How long the ova remain deposited before the young Eel is produced, is, I believe, unknown. The duration of this interval is very variable in different fishes. The roe of the Herring, deposited at the end of October or the beginning of November, is said to become living fry within three weeks : the ova of Eels, the produce of which is very small, do not probably require a longer period. Both the parent Eels and the fry occupying the brackish water appear to have the power of going either to the salt water or to the fresh without inconvenience, from the previous preparation which the respiratory organs have undergone, and many of both are found in pure sea water : the great bulk of the young, however, certainly ascend the stream of the river, and their annual appearance in certain places is looked for with some interest. The passage of young Eels up the Thames at Kingston in the year 1832 commenced on the 30th of April, and lasted till the 4th of May ; but I believe I am correct in stating that few young Eels were observed to pass up the Thames either in the year 1834 or 1835. Some notion may be formed of the quantity of young Eels, each about three inches long, that pass up 292 MUR^ENIIXE. the Thames in the spring, and in other rivers the beginning of summer, from the circumstance that it was calculated by two observers of the progress of the young Eels at Kingston in 1832, that from sixteen to eighteen hundred passed a given point in the space of one minute of time. This pas- sage of young Eels is called ftel-fare on the banks of the Thames, — the Saxon word signifying to go, to pass, to tra- vel ;* and I have very little doubt that the term Elver, in common use on the banks of the Severn for a young Eel, is a modification or corruption of Eel-fare. " When the Elvers appear in the Severn, they are taken in great quantities with sieves of hair-cloth, or even with a common basket, and, after being scoured and boiled, are offered for sale. They are either fried in cakes or stewed, and are accounted very delicious." There is no doubt that Eels occasionally quit the water, and when grass meadows are wet from dew, or other causes, travel during the night over the moist surface in search of frogs and other suitable food, or to change their situation. Some ponds continually produce Eels, though the owners of these ponds are most desirous of keeping the water free from Eels, from a knowledge of their destructive habits to- wards the spawn and fry of other fishes. Other ponds into which Eels have been constantly introduced are obnoxious to them from some quality in the water ; and they are known to leave such places during the night, and have been found on their passage to other retreats. Dr. Hastings, in his Illus- trations of the Natural History of Worcestershire, says at page 134 : "I will here mention a curious confirmation of the opinion in favour of the overland migration of Eels. A * A pedestrian on the road is called " a way-faring man ;" and hence, also, the price for travelling by a conveyance is called "the fare." We have also " thoroughfare," &c. SHARP-NOSED EEL. 293 relative of the late Mr. Perrott was out in his park with his keeper near a large piece of water, on a very beautiful even- ing, when the keeper drew his attention to a fine Eel quietly ascending the bank of the pool, and with an undulating motion making its way through the long grass : on further observation he perceived a considerable number of Eels qui- etly proceeding to a range of stews, nearly the distance of a quarter of a mile from the large piece of water from whence they started. The stews were supplied by a rapid brook, and in all probability the instinct of the fish led them in that direction as a means of finding their way to some large river from whence their ultimate destination, the sea, might be obtained. This circumstance took place at Sandford Park, near Enstone." That Eels breed also in the fresh water of inland rivers and lakes from which they are unable to visit the sea, is, I believe, certain. A constant supply for the table is obtained throughout the winter in these localities, as well as at other seasons, by gamekeepers and fishermen, who have charge of waters thus situated ; and no doubt exists in their minds that these Eels are bred in the places from which they are ob- tained, and of which the great variation that occurs in the size is an additional proof. The Eel is a voracious feeder during certain months of the year. In winter the stomachs of those which I examined were empty : by the middle of March I found the stomachs of others distended with the larvae of various insects, and the bones of small fishes. They are known to consume a large quantity of spawn, and will attack large Carp, seizing them by the fins, though without the power of doing them further injury. Occasionally they eat vegetable substances, and have been seen swimming about the surface of water, cropping the leaves of small aquatic plants. By means of a long and capacious air-bladder. Eels rise to various elevations in the water with great ease, and sometimes swim very high even in deep water. When Whitebait-fishing in the Thames, I once caught an Eel in the net in twenty-six feet depth of water, though the Whitebait-net does not dip more than about three feet below the surface. Eels appear to be slow of growth, not attaining greater length than twelve inches during the first year, and do not mature roe till the second or third year. The sharp-nosed species, however, acquires a large size. I saw at Cambridge the preserved skins of two which weighed together fifty pounds ; the heaviest twenty-seven pounds, the second twen- ty-three pounds. They were taken on draining a fen-dyke at Wisbeach. Ely is said to have been so named from rents being for- merly paid in Eels : the lords of manors in the isle were annually entitled to more than 100,000 Eels. A stich or stick of Eels was twenty-five ; and the practice of stringing Eels on tough slender willow-twigs, put in at the gill-aper- ture and out at the mouth, still prevails in Dorsetshire among those who carry Eels about for sale from house to house ; one, two, or three pounds' weight being thus strung on a stick, to suit different customers. Elmore on the Severn obtained its name from the immense number of Eels which are taken there. SHARP-NOSED EEL. 295 In a sharp-nosed Eel of twenty-two inches in length, three distances taken from the point of the lower jaw are to the whole length of the Eel as follows : — to the upper part of the base of the pectoral fin, as two to seventeen ; to the com- mencement of the dorsal fin, as two to seven ; and to the com- mencement of the anal fin, as nine to twenty-two. In a sharp- nosed Eel of twenty inches in length, the pectoral fin will be almost one inch, and the vent more than an inch, nearer the head than the same parts in a broad-nosed Eel of the same length. The head is compressed, the top convex, depressed as it slopes forward : the eyes small, placed immediately over the angles of the mouth ; irides reddish yellow : the jaws very narrow, slightly rounded at the end ; the lower jaw the long- est : nostrils with two openings on each side, one tubular, the other a simple orifice ; both jaws furnished with a narrow band of small teeth ; gape small ; various mucous pores about the mouth and other parts of the head ; gill-open- ing a small aperture immediately before and rather below the origin of the pectoral fin ; the scales on the body rather small : dorsal fin extending over more than two-thirds of the whole length of the fish ; anal fin occupying more than half of the whole length ; both united at the end, forming a tail ; the number of rays in the fins not easily ascertained, from the thickness of the skin ; the lateral line exhibits a long series of mucous orifices; vertebrae 113. The vent includes four distinct openings, the most anterior of which leads upwards to the intestine, the posterior to the urinary bladder in a direction backwards, and one elongated lateral opening on each side communicating with the cavity of the abdomen, as in other bony fishes. The cranium on the right hand of the three, figured at page 303, is that of the sharp-nosed Eel. 296 The prevailing colour of all the upper surface is a dark olivaceous green ; the sides lighter ; the belly white. When the fish are obtained from pure streams, the colours are clear and bright, and it is called a Silver Eel ; when taken from water over a muddy bottom, the colours are brown and dusky. Dr. Marshall Hall, in 1831, while pursuing some physiolo- gical investigations on the circulation of the blood in various reptiles and fishes, observed a pulsating sac near the tail of the Eel. The form, action, and connexions of this sac are best seen under the microscope. A young Eel of six or seven inches in length, if rolled up in a strip of linen cloth, leaving out a small portion only of the tail, will remain quiet when placed on a long slip of glass, or may be tied to it with thread. The pulsation observed in this sac is entirely inde- pendent of the action or influence of the heart, and the num- ber of beats more than double in the same period of time ; they also continue after the heart has been removed. Some Continental physiologists have ascertained that these pulsating sacs, which are found in the frog, the toad, the salamander, and the green lizard,* contain lymph, and direct its motion, and they have accordingly called them lymphatic hearts. They are only observed in connexion with veins. " Such is," says Dr. Muller, " the pulsating organ discovered by Dr. Marshall Hall at the end of the vena caudalis of the Eel, where that organ receives the venous branches of the extremity of the tail, and conducts its blood into the vena caudalis. But organs of pulsation in the lymphatic system have hitherto been altogether unknown ; it is not probable that they should exist only in amphibia, and important dis- coveries of a like nature in the higher animals, such as birds * See a paper in the Philosophical Transactions for 1833, by Dr. John Muller, Professor of Physiology in the University of Bonn. SHARP-NOSED EEL. 297 and mammalia, may be expected ; my researches, as regards these, have however been hitherto unsuccessful.1' In an- other part of his paper, Dr. Muller observes, " I have never discovered a trace of motion in the cy sterna chyli and ductus thoracicus of mammalia.11 In a conversation with Mr. Owen on this subject, he sug- gested, that as the valves of the lymphatic vessels are very few and imperfect in reptiles and fishes, especially in the latter, these pulsating sacs would seem to be superadded as a com- pensating power in the absence of that mechanism which impresses a definite direction and an unintermitting flow upon the currents of the lymph in the higher vertebrata, especially mammalia. I am indebted to the kindness of Dr. Marshall Hall for permission to copy the excellent illustration of this structure in the tail of the Eel, from his very interesting critical and experimental essay on the circulation of the blood. In the vignette the arrow-heads indicate the direction of the currents. VOL. II. 298 APODAL MALACOPTERYGIL MUR&N1D&. THE BROAD-NOSED EEL, Anguilla latirostris, Broad-nosed Eel, YARRELL, Proceed.

THE BROAD-NOSED EEL is almost as common a species as the Sharp-nosed Eel, but is immediately distinguished from it by the much greater comparative breadth of the head ; the representation at the top of the page is therefore confined to that part of the fish which exhibits the best distinctions ; and the vignette to the Snig Eel, page 303, represents in the left-hand figure of the three heads the cra- nium of the Broad-nosed Eel, to show this character as it exists in the bone. This Eel is the Grig or Glut Eel of Pennant, who says, " They have a larger head, blunter nose, and thicker skin than the common sort." It is, probably, also the Frog-mouthed Eel of the Severn, referred to by Dr. Hastings, in his Natural History of Worcestershire, BROAD-NOSED EEL. 299 page 135, and so called by the fishermen from the extraor- dinary width of the mouth. In its habits the Broad-nosed Eel has not been distin- guished by any peculiarity that I am aware of from the other common Eel ; but it does not appear to attain so large a size, the largest I have seen not exceeding five pounds in weight. It exists in many of the waters which produce the Sharp- nosed Eel, is much thicker in the body in proportion to its length, and fishermen can distinguish this species readily when fishing in the dark by its more soft and unctuous feel in the hand. The term Grig is, however, in and about London, ap- plied to a particular Eel of small size, of which the figure here introduced represents the head. This Eel is the An- guille plat-bee of Cuvier, Regne Animal, torn. ii. p. 349, who considers it a distinct species. It is the Grig Eel also of Mrs. Bowdich's British Fresh Water Fishes, No. 28, in which work the three Eels already spoken of here are well figured ; and the species were considered by Cuvier as iden- tical with those of the Regne Animal. The name Grig is also applied by Thames fishermen to any small-sized Eel of any species when not longer than eight or nine inches, and of which eight or ten are required to make up a pound weight. In a Broad-nosed Eel of twenty-two inches in length, three distances taken from the point of the lower jaw are to the whole length as follows : — to the upper part of the base 300 MUR.ENID.E. of the pectoral fin, as two to thirteen ; to the commencement of the dorsal fin, as one to three ; and to the commencement of the anal fin, as ten to twenty-two. The Broad-nosed Eel has the head rounded at the back part, and flattened from the eyes forward ; both jaws broad and blunt ; the lower jaw the widest, and longer than the upper : nostrils double, one tubular, the other a plain orifice ; the gape large ; lips fleshy : teeth more numerous than in either of the other British fresh-water species, larger, strong- er, and forming a much broader band in each jaw : the eyes large, placed before the line of the gape ; irides golden yel- low : the gill-openings, pectoral fins, the commencement of the dorsal fin, and the vent, placed farther back than in the Sharp-nosed Eel ; dorsal and anal fins also much deeper and thicker ; the tail broad and rounded ; the body of the fish thicker for the same length than in other Eels : the number of vertebrae 115. The colour of the upper surface of the body is a dark- greenish brown, subject to some variation, depending on lo- cality, soil, and the quality of the water.

I AM indebted to the kindness of Mr. Jesse, and his friend, Francis Mills, Esq. for the only specimens of this Eel I have yet seen ; and from some differences in its exter- nal characters, in its habits, and also in the comparative size of the head, as well as some peculiarity in the five cervical verte- brse that are nearest the head, I believe it to be a different species from either of those previously described in this work. The specimens I have had were from the Avon in Hamp- shire, where this Eel, rather remarkable for its yellow colour, is called the Snig, and is considered distinct from the other well-known and more common Eels. Dr. Hastings, in the Appendix to his Illustrations of the Natural History of Worcestershire, page 135, says, that besides an Eel called the Frog-mouthed Eel by the fisher- men, from the extraordinary width of the mouth, — identical, probably, with the Broad-nosed Eel of this work, — u there are two distinct kinds of Eels in the Worcestershire Avon, the Silver and Yellow Eel," which last may be similar to the Snig of the Avon of Hampshire. 302 MUR.ENI1XE. The term Snig, it should however be stated, is in some counties a general name for any sort of Eel ; and a particular mode of fishing for Eels, which is described in most of the works on Angling, is called Sniggling. The Hampshire Snig differs from our other Eels in its habit of roving and feeding during the day, which other Eels do not. It is considered excellent as an article of food, and of a superior flavour to other Eels : it does not however attain a large size, seldom exceeding half a pound in weight. The fishermen make a certain difference in the mode of placing their eel-pots when they are desirous of catching Snigs ; finding by long experience that the Snigs get into those pots the mouths of which are set in the opposite direc- tion, in reference to the stream, to others in which the com- mon Eels are taken. In the comparative breadth of the nose, the Snig is inter- mediate in reference to the Sharp and Broad-nosed Eels, but rather more resembles that with the sharp nose ; it has a slight but elongated depression extending from the anterior edge of the upper jaw to the upper and back part of the head ; the tubular openings of the nostrils are longer, and the mucous pores about the lips larger and more conspicuous ; both jaws rounded at their extremities, the lower one the longest ; teeth longer and stronger than in the common sharp- nosed species ; gape large ; the angle and the posterior edge of the eye on the same vertical line ; the pectoral fins, the commencement of the dorsal fin, and the vent, are each placed nearer the head than in either of our fresh- water Eels. The general colour olive green above, passing by a lighter green to yellowish white below. Desirous of obtaining internal characters of distinction among our fresh-water Eels, I prepared skeletons of each species, selecting three examples that measured exactly the SNIG. 308 same length, in order to afford a more just comparison. The vignette at the bottom of the page represents correctly the relative size and power of bone in each species. The cra- nium on the left is that of the Broad-nosed Eel ; that in the middle is from the Snig ; the head on the right hand is from the Sharp-nosed Eel. It is obvious that each is able to overcome a larger and more powerful victim as food than the other. It will also be seen, that independent of some difference in the length and form of some of the bones, as well as in the size of the head in the middle, belonging to the Snig, as compared with that on either side, there is a cha- racteristic distinction in the form of the bones of the verte- bral column. The first five cervical vertebrae are smooth and round, entirely destitute of superior or lateral spinous processes, both of which are possessed by the other two, of a size corresponding to the character of the vertebral bone it- self to which it belongs. With this exception, the skeleton of the Snig most resembles that of the Sharp-nosed Eel ; but is somewhat stronger, and particularly so in the processes of the other vertebrae generally. 304 MU R.ENID*:.

THE CONGER EEL is a marine species well-known on all the rocky parts of the coast of the British Islands, but nowhere more abundant than on the coast of Cornwall. Mr. Low says, "It is found very frequently round the Orkney Islands : some are caught at the fishermen's lines ; but the otter is by far the most successful in killing Congers. He brings them ashore, and eats but a very small part, leaving the rest for the next comer ; and where his haunts are known, the country people are very careful every morning to search for the remains of the night, and are seldom disap- pointed, but find Cod, Ling sometimes, but especially Con- gers, which are oftener seen amongst the deep hollows of the rocks than farther to sea." CONGER. 305 Dr. Neill says this species is sometimes, but not very often, found in the Forth ; and, in proof of great tenacity of life, mentions having seen one alive and vigorous in the Edinburgh market, although it had been ten hours out of water. The Conger is frequently caught at various rocky parts of our eastern, coast, and I have known specimens of large size taken in winter about the mouth of the Thames. Congers are caught by bulters, or long-lines, and hand-lines — modes of fishing already described, and the most esteemed bait is the sandlaunce. " So well assured," says Colonel Montagu, " are the French fishermen of the advantage derived from the use of this little fish, that the fishing-boats in times of peace run over from the coast about Dieppe to Slapton Bay, on the south coast of Devon, on purpose to purchase launce ; and for that purpose alone do some of our fishermen keep fine nets for the purpose of supplying bait to these foreigners, for which they obtain about twenty-pence the bushel. Some principal Conger banks lie off the French coast, from which a prodigious quantity are taken to feed the poorer classes on maigre days. The principal fishery for Congers in this country is on the Cornish coast ; where, according to Mr. Couch, it is not uncommon for a boat with three men to bring on shore from five hundredweight to two tons, the fishing being performed during the night ; for this fish will not readily take a bait by day, and even on moonlight nights it is more shy than when in the dark, except in deep water. The most usual bait with the Cornish fishermen is a Pilchard. The Congers that keep among rocks hide themselves in crevices, where they are not unfrequently left by the retiring tide ; but in situations free from rocks, Congers hide themselves by bur- rowing in the ground. 306 MUR^NID^E. The flesh is not in much estimation, but meets a ready sale at a low price among the lower classes. Formerly a very considerable quantity was prepared by drying in a par- ticular manner, and exported to Spain : Bayonne also re- ceived a part. When thus dried, the flesh was ground or grated to powder, and in this state was used to thicken soup. Congers spawn in December or January ; and the dis- tinction of the sexes is obvious on the examination of the roe during the cold months. Small ones, about the size of a man's finger, are found among rocks, close to land, during the summer. The small Eels which ascend the Severn in such numbers in the spring, and were considered by Wil- lughby and Pennant as the young of the Conger, are in reality the young of fresh-water Eels. The adult fish is most voracious, not sparing even those of its own species. From the stomach of a specimen weigh- ing twenty-five pounds, I took three common Dabs, and a young Conger of three feet in length. The power of the jaws in this fish is very great : in the stomach of small spe- cimens examined on the coast, I have found the strong tes- taceous coverings of our shell-fish comminuted to fragments. They are often tempted by the Crustacea entrapped in the lobster-pots to enter those decoys in order to feed on them, and are thus frequently captured. Congers acquire a very large size. Specimens weighing eighty-six pounds, one hundred and four pounds, and even one hundred and thirty pounds, have been recorded, some of them measuring more than ten feet long, and eighteen inches in circumference. They possess great strength, and often prove very formidable antagonists if assailed among rocks, or when drawn into a boat on a line. Three measurements taken from the point of the nose, as in the fresh-water species, give the following proportions in CONGER. 307 • reference to the whole length : — the distance to the origin of the pectoral fin is as two to thirteen ; to the commencement of the dorsal fin, as one to five ; and to the vent, as two to five. The head is long and depressed : the upper jaw the long- est ; both jaws furnished with strong teeth, forming a broad band in each : the lips fleshy : the nostrils double ; the most anterior near the edge of the lip, and tubular ; the other a simple orifice : numerous mucous pores about the parts of the mouth and head : the mouth deeply divided, making the gape long ; the angle forming a tangent with the posterior edge of the pupil : the eyes large ; body nearly cylindrical ; dorsal fin commencing but little behind the pectorals, ex- tending along four-fifths of the whole length of the body ; anal fin commencing immediately behind the vent, and ex- tending along three-fifths of the whole, and joining the dor- sal fin, forms a pointed tail. The colour of the upper surface of the body is a uniform pale brown, becoming lighter on the lower part of the sides, and passing into dull white underneath ; the dorsal and anal fins whitish, edged with black ; lateral line almost white. The notion entertained by some, that river Eels on going to the sea remain there and become Congers, scarcely re- quires a serious remark. No one who looks for specific dis- tinctions can fail to observe them when comparing either of our fresh-water Eels with the Conger. These differences, which extend to colour, form of body, and situation of fins, receive further confirmation on examining their internal struc- ture : independent of comparative difference of relative posi- tion in some of the most important of the viscera, the great- est number of vertebrae found in our fresh- water Eels is 116, those of the Conger amount to 156. 308 APODAL MALACOPTERYGJJ.

The vent is exactly half-way between the two ends of the body, from whence proceeds a line to the end of the tail parallel to the anal fin, and half an inch from its base : this line must be the lateral line, since there is no appearance of any other. The dorsal fin begins five inches and a half from the snout, and proceeds round the extremity of the body to join the anal, which begins at the vent ; but these fins are thick and fleshy, and not readily distinguished from the margin of the body. The ground colour of the anterior part of the body is a fine lively yellow, the hinder part a fine purple ; but the whole, including the fins, is divided into segments, forming irregularly shaped spots, which yet have a tendency to re- gular distribution ; towards the tail the yellow spots more resemble irregular rings, with larger spaces between them ; the whole is interspersed with innumerable spots of whitish and deep yellow, golden, brown, and purple, forming a most beautiful arrangement : under the thorax and to the gill- opening are a few lines marked in the skin as if to facilitate motion, though the skin is exceedingly smooth and soft ; 310 it is strong also, and the colours were remarkably slow to fade, contrary to what is observed in most fishes. This spe- cimen was taken with a line, and manifested great strength after it was taken on board the boat. Of this singular, and beautifully marked fish Mr. Couch very kindly sent me for my use a coloured drawing made from the fresh specimen, from which the figure on the preced- ing page, carefully reduced in size, was drawn and engraved. This Mursena is considered very common in almost every part of the Mediterranean. It was a great favourite with the ancient Romans, who preserved large quantities of them in their numerous vivaria, where they were fed with great care. On the celebration of one of his triumphs, Caesar dis- tributed six thousand specimens of this Mursena among his friends. The flesh is said to be delicately white, and very agreeable eating. In the Mediterranean it is fished for with lines. It is very voracious, and its bite is very severe, which, from the nature of the teeth, and the large size of the muscles about the head, might be expected. This fish is said to live with equal facility in fresh or salt water, though generally found at sea. The vignette represents a Venetian pleasure-boat. ANGLESEY MORRIS. 311 APODAL MALACOPTERYG1I.

THIS species was discovered in the sea near Holyhead by Mr. William Morris, who sent the specimen to Pennant, by whom it was named after his friend. Pennant subsequently sent the same specimen to Gronovius, who described it under the generic name of Leptocephalus , in reference to the small size of the head. Any doubts which might formerly have been raised as to the real existence of such a species, to which Colonel Montagu has alluded, must have ceased to exist, as this fish has now been taken and recognised in various localities. Pennant in his first description, perhaps from the state of his specimen, was not aware of all the characters this delicate fish possesses; but Colonel Montagu has well described and given a figure 312 MUR.ENID.E. of it in the Wernerian Memoirs, as quoted. More than twenty specimens have within a few years been taken at dif- ferent parts of the coast of England, Wales, and Ireland. By the kindness of Mr. Couch, I possess three examples that were taken in Cornwall ; and from Mr. William Thompson, of Belfast, we learn that five or six specimens have been ob- tained by him and his collecting friends. There is also an interesting account of this fish, with a good figure, in the sixth volume of Mr. London's Magazine of Natural History, page 330, by H. V. Deere, Esq. who states that his specimen, to all appearance dead, was brought to him by a Devonshire fisherman, who had carried it in his pocket, wrapped in brown paper, for three hours. After this gentleman had held the fish in his hand for about a minute, examining it, symptoms of life appeared, and then the little animal was placed in a tumbler of salt and water, where it survived its incarceration in brown paper for several hours. Its appearance is described as most pleasing, from its semitransparent and silvery hue, its prominent eye, and graceful motions. It is usually found among seaweed. I carefully dissected off the whole of one side from one of the three specimens sent me by Mr. Couch, laying bare the vertebral column and the intestinal canal. The bones form- ing the vertebrae have no spinous processes whatever, either superior or inferior ; the angles of the ascending and de- scending oblique indented striae, visible on the external sur- face of the skin, mark the points of union of the different vertebrae ; the oblique muscles between the striae are attached to the bodies of the bones forming the column ; the margin all round each vertebral bone is opaque, but the centre or body of each is transparent. The intestine is a single straight canal of small calibre, reaching from the head to the vent ; after passing from the ANGLESEY MORRIS. 313 posterior part of the head, it descends to the abdominal line, which it traverses without convolution to the vent. This canal may be distinctly seen in the perfect fish when placed flat on a slip of glass, and looked at against a good light, particularly the descending portion from the head to the level of the abdominal line. The head is small, short, and rather blunt : the eyes large ; irides silvery, the pupil dark : the lower jaw slender ; teeth in both jaws, numerous and minute : gill-openings and pec- toral fins very small ; the body behind the head becomes deeper, very much compressed, as thin as tape, and when rendered opaque by the effect of a mixture of spirit of wine and water, which is the best mode of preserving them, this fish very much resembles a piece of a tape-worm. The dorsal fin commences rather before the middle of the whole length of the fish ; the anal fin rather behind it ; and both extend to the tail, where they are united, and end in a point. These fin-like appendages have the appearance of an extension of the skin, and are so delicate that it is not al- ways easy to decide where they do begin, or may be called fin ; the dorsal and abdominal margins, as well as the lateral line, exhibit a series of small black specks : the obliquely striated appearance of the sides has been already referred to. The general colour is most like that of opal. I have had opportunities of examining specimens from the Mediterranean which were identical with those from Cornwall, as well as those described and figured in the En- glish works already referred to. M. Risso includes but one species in his fishes of Southern Europe and the Environs of Nice, which he has named Leptocephalus Spallanzani, torn, iii. p. £05 ; but the description so exactly accords with English specimens, that I have no doubt it is the fish I have seen, and the same as that on our own shores.

THE BEARDLESS OPHIDIUM was first added to the ca- talogue of British Fishes by Pennant, to whom it was com- municated by the Duchess of Portland : the specimen was found near Weymouth. Pennant gave a figure of his fish in the Appendix to the fourth volume of the British Zoolo- gy, edition of 1777, but no description. Colonel Montagu afterwards obtained a specimen on the south coast of Devon, which is figured and described in the first volume of the Wernerian Memoirs, as quoted. The editor of the edition of Pennant's British Zoology, published in 1812, left out the figure of the Beardless Ophidium, given in the previous edition, but copied the figure and description of Colonel Montagu. BEARDLESS OPHIDIUM. 315 Never having seen a specimen of this fish. Colonel Mon- tagu^s figure and description are here given, with some addi- tions to be hereafter explained. " Length about three inches ; depth about a quarter of an inch. The head is very obtuse, and rounded in front : eyes large, placed forward and lateral ; irides dark, with a circle of silver round the pupil : mouth, when closed, inclines oblique- ly upwards ; the lips are marginated : the gill-membranes inflated beneath. The body is ensiform, considerably com- pressed towards the tail, and in shape is not unlike that of Cepola rubescens, vol. i. page 195, of this work; the lateral line is nearly in the middle, originating at . the angle of the operculum to the gills, but rather obscure : vent nearly in the middle : the pectoral fin is rounded : the dorsal fin com- mences immediately above the base of the pectoral, and is at first not so broad, and usually not so erect, as the other part : the anal fin commences at the vent, and, together with the dorsal, unites with the caudal fin, which is cuneiform, but obtusely pointed. The colour is purplish brown, disposed in minute speckles ; and along the base of the anal fin are about ten small bluish-white spots regularly placed, but scarcely discernible without a lens, and possibly peculiar to younger fishes : all the fins are like the body in colour, ex- cept the pectoral and caudal ; the first is pale, the last is yellowish."" The fin-rays in number are — D. 77 : P. 11 : A. 44 : C. 18 or 20. 316 MUB^ENIDJE. " This fish," Colonel Montagu observes, " does not ap- pear to be very tenacious of life, like some of the Blennies, as it was placed in a tin box with the Crested and Smooth Blenny, covered with wet seaweed, and although these were lively, the Ophidium was dead before it could be got to his house. It died with its mouth shut, the pectoral fins thrown forward, and the body curved a little near the vent, throwing the head upwards." " Little can be said of the natural habits of this fish ; but as it so rarely occurs, it is most probably an inhabitant of the rocky parts ; in such a situation, at low-water, the specimen here described was taken." But little being known either of Montagu's or Pennant's Ophidium, the figure at the head of this subject is taken from Montagu's figure, and the outline at the foot of the preced- ing page is taken from Pennant's first figure, which Schneider appears to have adopted as the representative of the genus Ophidium in his Ichthyological work. The Ophidium barbatum, or Bearded Ophidium, has also been included by Berkenhout in his Catalogue of British Fishes ; but whether on the personal authority of that au- thor, or on what part of the British coast it was observed, no mention is made. The figure below is a representation of the Bearded Ophidium ; and the three woodcuts here given may assist investigators, should any species of Ophidium come to their hands.

Brit. Fish. pi. 33 ? Generic Characters. — Head and body elongated ; gill-openings large ; dor- sal fin extending nearly the whole length of the back ; anal fin of considerable length ; dorsal and anal fins separated from the caudal fin. WE are indebted, says Baron Cuvier, to M. Lesauvage, of Caen, for pointing out -the true distinctions in the two species of Ammodytes belonging to the shores of the Chan- nel, A. Tobianus and A. Lancea, the first of which is rare, but the second very common. Our excellent naturalist and countryman Ray, has given us, in his Synopsis, from Jago^s Catalogue of Cornish Fishes, a good figure of the true Tobianus; but it was not, I believe, 318 ANGU1LLID.E. till the recent publication of Mr. Jenyns' valuable Manual of British Vertebrate Animals, that any English zoologist had admitted two species among British Fishes. Shaw, in his General Zoology, vol. iv. p. 81, plate 9, has figured both species, but with only one name, and but one description.* Ray, in his short notice from Jago's Catalogue, calls his Ammodytes Anglorum verus the true Sand-Eel ; and his figure leaves no doubt that his fish is the same as the 7V bianus of Linnaeus, Bloch, and others. In the late Colonel Montagu's copy of Berkenhouf s Synopsis of the Natural History of Great Britain, there is a note in Montagu's writing, which states, " That at Teignmouth a distinction is made between the Sand-Eel and Sand-launce, by the size and superior length of the head and gills in the one ; it is also said to be much more rare." The rarity and greater length of the head are both on the side of the Tobianus, the Sand-Eel, which, as far as my own observation goes, is much more scarce than the smaller-sized species with the shorter head ; I am therefore desirous of preserving the dis- tinctive appellation of Sand-Eel to the longer fish, A. To- bianus, and continuing that of Sand-launce to the smaller species, bearing among naturalists the specific name of Lancea. M. Lesauvage gave the name of lanceolatus to the species which had been previously called Tobianus, his trivial name will therefore only be used as a synonym. Willughby's figure, G. 8, f. 1, appears to have been co- pied from Salvianus, and represents an Ammodytes with two small dorsal fins ; I have not, therefore, referred it to either of our fishes. The Sand-Eel is immediately to be distinguished from the Sandlaunce by its greater size, specimens now before me * Both specimens are also figured by Klein. SAND-EEL. 319 measuring twelve inches in length ; Ray^s fish was fifteen inches and a half long : it is further distinguished by the greater length of the head, and particularly of the lower jaw ; by the commencement of the dorsal fin being on a line with the end of the pectoral fin-rays : the dorsal fin of the Sandlaunce beginning in a line with the middle of the pec- toral fin, and the head smaller and shorter, as shown in the two representations here given. The habits of the two species are in many respects very similar, and will be more particularly referred to under Sand- launce, which being exceedingly common on all our sandy shores, has afforded greater opportunities for observation. Both species of Ammodytes are included by Professor Nilsson among the fishes of Scandinavia ; both species also occur in the Forth. Dr. Neill, in his account of the fishes of that locality, says, the Edinburgh fishermen call the large ones Hornels — probably an abbreviation of Horneels — in re- ference to the greater length of body and the horn-like elongation of the lower jaw, by means of which they are enabled to bury themselves in the wet sands of the sea-shore, from which they are scratched out with iron hooks for bait or sale. Stephen Oliver the younger, in his agreeable Rambles in Northumberland and on the Scottish Border, when describing the fishing in the Tyne, says, Sand-Eels follow the young fry of the Coalfish into the harbour, and are frequently caught with the same bait as the Poodlers (young Coalfish), which is used in a manner similar to fly-fishing for Trout. The common length of the Sand-Eel in the Tyne is from twelve to fourteen inches ; and their jaws, by a peculiar con- formation, admit of great expansion. They swim rapidly, and dash at a shoal of fry with the voracity and swiftness of a Pike. Mr. Couch says that a large specimen caught on 320 ANGUILLID.E. a line by a Cornish fisherman had a small fish of its own species in its stomach. From the extreme point of the lower jaw to the posterior end of the gill-cover is to the whole length of the fish as one to four and a half ; the depth of the body rather less than one-third of the length of the head ; the lower jaw very much elongated, with a strong, indurated projection at the extreme tip ; the upper jaw much shorter than the lower, with a strong forked tooth of two points descending from the vomer : the nostrils double ; both open on each side on a line, one before the other, about half-way be- tween the eye and the point of the nose : the eyes rather small ; the posterior margin exactly half-way between the point of the under jaw and the posterior angle of the gill- cover : the shape of the body very nearly round ; covered with small scales : the pectoral fin arises under the posterior angle of the gill-cover, its length one-third that of the length of the head ; the dorsal fin placed in a groove, with a prominent line extending along each side ; the rays com- mence in a vertical line over the end of the pectoral fin- rays, and end near the tail ; the lateral line indented and straight; the abdomen with three indented parallel lines extending to the anal aperture, which has another orifice behind it ; along the whole line of the lower part of each side extends a narrow and slender membrane attached by one edge ; the anal fin is about one-third of the whole length of the fish, ending short of the caudal fin, and nearly on the same plane as the dorsal fin ; the tail forked. The fin-rays in number are — D. 55 : P. 15 : A. 29 : C. 17.

On account of its silvery brightness, it is in great estimation and constant use with fishermen as bait for the hooks of their sea and hand lines ; and the habit peculiar to the species of burying themselves in the wet sand as the tide recedes affords easy means of capture. The generic term Ammodytes, refers to this power of digging in sand. With the projecting por- tion of the under jaw, aided by the muscular power of the fish, and its slender form, it is enabled to bury itself with rapidity five or six inches deep in the soft sand as the ebbing sea retires, and releases itself again on the approach of the ensuing flood-tide, apparently uninjured, though deprived of SAND-LAUNCE. 323 water for several hours : another instance of a low degree of respiration and great tenacity of life in a genus of fishes having very large gill-apertures. In Orkney, Mr. Low says it is constantly used as a bait for other fish, and though of good flavour, is very seldom eaten. On the sands at Portobello, near Edinburgh, as well as at other localities in that vicinity, people of all ages may be seen, when the tide is out, diligently searching for the Sand-Launce, and raking them out with iron hooks. Some are used as bait ; but many are prepared for table, and con- sidered delicate food. Colonel Montagu mentions the Sand-Launce as being ex- tremely plentiful at Slapton Sands, on the south coast of Devonshire, where the fishermen employ a small seine with a fine mesh, and are frequently so successful, that six or seven bushels are taken at one haul : these are usually sold to Dieppe fishermen for twenty-pence the bushel. Mon- tagu adds, that on the part of the Devonshire coast here referred to, even the poorest people would not eat the Sand- Launce, while at Teignmouth it was in great request as food, and was counted out for sale by the score. " It is only of late," says Mr. Couch, " that naturalists have learned to recognise two species, though it has been done long since by fishermen, who have been accustomed to observe that a small species, which keeps in larger bodies, and seldom goes far from land, is more followed by Mackerel than the others, and that its presence is a better sign of good fishing. On a calm evening it is an interesting sight to see the surface of the water broken by the repeated plunges of voracious fishes as they burst upon the little schull of Launces from beneath. Their only certain place of refuge from these pursuers is the sand. I have obtained the fry of the Sand-Launce four inches ANGIULLIDJS. long in the month of April, and considered them to be the young of the preceding year. May, August, and December, have each been named as the month in which the adult fish deposit their spawn ; but the habits and economy of the two species have been greatly confounded hitherto, under the supposition that they were but examples of the same fish, differing only in size. The Sand-Launce has been noticed on the coasts of the counties of Londonderry, Antrim, Dublin, and Cork ; I learn also from F. C. Lukis, Esq. that both species are found at Guernsey ; but that Lancea is the most common. The search for them in the sand prevails there, but it is usually made on moonlight nights. The food of the Sand-Launce is marine worms and very small fishes. The usual length of this species is from five to seven inches : the length of the head compared to the length of the fish is less than as one to five : the lower jaw shorter in proportion than in the other species ; the protractile portion of the upper jaw much more free to move, and when the lower jaw is pressed down, this moveable part comes forward and downward : the posterior margin of the eye is less than half-way between the point of the lower jaw and the poste- rior projecting angle of the gill-cover, being placed nearer the nose than in Tobianus ; the dorsal fin commencing in a line over the middle of the pectoral fin. The fin-rays in number are — D. 51 : P. 13 : A. 25 : C. 15. In other respects, as to the lines along the body and the colour of the various parts, the two species are very similar.

The figure on the left hand of the vignette at the bottom of the page, represents one side of the pectinated gills of a Pike ; that in the centre is drawn from the head of a spe- cimen of S. acus, to show the gills in small tufts, the oper- culum being removed : the right hand figure exhibits the head of the river Lampern, part of the skin on the side of the neck being removed to show another form of branchial apparatus, in which portions of the gills occupy different cells. The fish will be described hereafter, and this struc- ture referred to. These delicate tufts in the Pipe-fishes are defended ex- ternally by a large and hard operculum, having an aperture in the connecting membrane at its upper and posterior part. The fishes of this limited family are further remarkable for the extreme tenuity of their bodies, as well as for the num- ber and arrangement of the indurated and sculptured plates by which their lengthened bodies are defended. They are frequently called Needle-fish. The five species of British Syngnathi require to be ar- GREAT PIPE-FISH. 327 ranged in two divisions ; the first of which includes two species, having dorsal, pectoral, anal, and caudal fins ; the three species of the second division possess the dorsal fin only : neither of the five species possess ventral fins. The mode in which the young are produced is very singular, but very different in the two divisions, which will be explained when describing the species. The natural history of the Syngnathi appears not to have been so well understood, nor the species so clearly defined by the older authors as those of many other genera. By giving, in this work, figures taken from the specimens, and adding besides, as vignettes, enlarged representations of those parts which assist in determining specific distinction, five species, it is hoped, will be made out ; and only those actually obtained on the British coast, and of which specimens are preserved, will be included. They are all marine. Syngnathus acus, or the Great Pipe-fish, is one of the most common species, and is found on many parts of the coast, sometimes at low-water among seaweed, at other times in deep water. It is believed that the habit of proceeding to deep water at two different periods of the season has re- ference to important and interesting changes connected with the production of the young. In a MS. History of British Fishes, written by the late John Walcott, Esq.* during his residence at Teignmouth in the years 1784 and 85, and which has been most kindly lent to me by his son, William Walcott, Esq. with liberty to make any use of it in the present work, I found a state- ment in reference to the sexes of S. acus, which has since been confirmed by four Continental naturalists, and which * Author of various published works on Natural History. SYNONATHID.E. I have verified by repeated examinations. Mr. Walcotfs observation is as follows :— - " The male differs from the female in the belly from the vent to the tail fin being much broader, and in having for about two -thirds of its length two soft flaps, which fold to- gether, and form a false belly (or pouch). They breed in the summer ; the females casting their roe into the false belly of the male. This I have asserted from having ex- amined many, and having constantly found, early in the summer, roe in those without a false belly, but never any in those with ; and on opening them later in the summer, there has been no roe in those which I have termed the female, but only in the false belly of the male." On dissecting males and females the proof of the correct- ness of this new view was obvious. The anal or sub-caudal pouch is peculiar to the males only, and is closed by two elongated lateral flaps. On separating these flaps, and ex- posing the inside, the ova, large and yellow, were seen lining the pouch in some specimens, while in others the hemi- spheric depressions from which the ova had been but recently removed were very visible. In each of these the opened abdomen exhibited true male organs. The females examined had no anal pouch, and the opened abdomen exposed two lobes of ova of large size. In a specimen of a male of S. acus, obtained at Dover on the 20th of July 1835, and for which I am indebted to W. Christy, Esq. the opened abdo- men exhibited the preparatory organs of the male ; and the displayed sub-caudal pouch showed many eggs contained in it, the young of which were fully developed, and ready to escape from the capsules, while from others the young had actually escaped. They were rather more than one inch in length, and slightly barred with brown. In the plate devoted to Syngnathi, in the last two octavo GREAT PIPE-FISH. editions of Pennant's British Zoology, the upper figure re- presents the female, and the second figure the male of S. acus. The enlargement on the under surface of the second figure, looking like an elongated fin, marks the situation of the distended pouch of a male. Pennants third figure is the S. ophidian, and the fourth the S. lumbriciformis of this work. Neither S. typhle nor S. tequoreus are figured in the British Zoology. At what time or in what manner the ova are transferred from the abdomen of the female to the sub-caudal pouch of the male is, I believe, unknown. Mr. Walcott also adds, in his MS. that S. acus begins to breed when only four or five inches long. This I have also obtained proof of ; and although examples of this species not uncommonly occur of eighteen inches long, and Bloch attri- butes to it a length of two to three feet, I have a specimen, four inches long only, a young fish apparently of the pre- ceding year, in the opened abdomen of which the ova, in two small lobes, are full grown. M. Risso notices the great attachment of the adult Pipe- fish to their young, and this pouch probably serves as a place of shelter to which the young ones retreat in case of danger. I have been assured by fishermen that if the young were shaken out of the pouch into the water over the side of the boat, they did not swim away, but when the parent fish was held in the water in a favourable position, the young would again enter the pouch. The figures of S. acus and typhle are correctly represented by Rondeletius, and the characteristic difference in the form and size of the tubular mouth in each is well preserved. Below the figure, in that work, of the species now under consideration here, several of the young are represented as VOL. II. Z SYNGNATHID.E. swimming near the abdomen of the parent fish. This figure of Rondeletius is copied in Willughby, plate I. 25, fig. 6. Mr. Couch says, " This species may be seen slowly mov- ing about in a singular manner, horizontally or perpendi- cularly, with the head downwards or upwards, and in every attitude of contortion, in search of food, which chiefly seems to be water insects." From the great similarity in the form and size of the mouth in all the species, it is probable that their food is also similar. Worms, small mollusca, young and minute thin-skinned Crustacea, and the ova of other fishes, are among the substances taken ; and these Syngnathi are sup- posed to be able, by dilating their throat at pleasure, to draw their food up their cylindrical beak-like mouth, as water is drawn up the pipe of a syringe. From the point of the tubular mouth to the posterior edge of the indurated portion of the operculum, the length is, when compared to the whole length of the fish, as one to eight ; if measured to the edge of the shoulder, it is as one to seven and a half, and this proportion exists in specimens of various ages or lengths, from six inches to eighteen ; from the mouth to a projecting point at the an- terior edge of the eye, and thence to the origin of the pec- toral fin, the distances are equal : the jaws united, tubular, slightly compressed ; in depth but one-third that of the head at its deepest part, which is in a vertical line with the centre of the operculum : the mouth small, placed at the extremity of the tube, opening obliquely upwards ; the lower jaw the longest : eyes rather large, bony orbits pro- minent : operculum covered with radiating striae : the head between the eyes flattened ; behind the eyes, rising into a keel-like crest, which reaches to the neck : from the pecto- ral fin to the anal aperture the body is deepest and hept- GREAT PIPE-FISH. 331 angular, with three ridges along each side, and one along the abdomen, which ends at the vent ; the surface defended by a series of nineteen plates ; throughout the short extent of the dorsal fin the body is hexangular, the ridge of the abdomen being discontinued ; thence to the end of the tail, tapering, slender, and quadrangular, with a series of forty- four plates ; the pectoral fins are small ; the dorsal fin com- mences at two-fifths of the whole length of the fish, and in a vertical line rather before the anal aperture ; the longest rays not equal in height to the depth of the body ; the anal fin very small ; the tail rounded and fan-shaped.

THE DEEP-NOSED PIPE-FISH is immediately distinguish- ed from the preceding species by the more compressed form of the jaws, which are also so deep that the upper and lower edges are nearly parallel with the lines of the upper and under surface of the head. From the two large-sized Pipe- fish of the next division this species is easily known by the presence of pectoral, anal, and caudal fins. The figures in the works of Willughby and Mr. Donovan are good repre- sentations ; but I believe the figure in Bloch, part iii. plate 91, f. 1, which has usually been considered and referred to as Syngnathus typhle, to be only a representation of the young of S. acus. S. typhle has also been well figured by M. Laroche, in the Ann. de Mus. t. xiii. under the name of S. Rondeletii. DEEP-NOSED PIPE-FISH. 333 It is the S. viridis of M. Risso,* a term that seems liable to objection, even if a name were wanting, inasmuch as seve- ral other species are more or less green. The Deep-nosed Pipe-fish does not differ materially in its habits, that I am aware of, from the species last described. The ova are transferred from the abdomen of the female to the sub-caudal pouch of the male, and there hatched in the same manner. When fishing in ten or twelve feet water over a soft surface covered with weeds, using the small net described and figured in vol. i. page 212, I have taken both sorts together, finding the deep-nosed species abundant on the Dorsetshire coast. The whole length of the largest specimens I have seen was thirteen inches ; from the point of the closed jaws to the posterior end of the indurated portion of the gill-cover, the distance is, compared to the whole length of the fish, as one to six ; the head larger than in S. acus, and without the elevated ridge on the top of it ; the distance from the point of the upper jaw to the projecting tubercle in front of the eye, and thence to the end of the pectoral fin, equal ; the united jaws are very much compressed, and nearly as deep as the head, only slightly inclining to a slope before the eyes ; the body hexangular ; the middle lateral angle on each side becoming the upper angles of the quadrangular tail at the end of the dorsal fin. This fin commences farther back than in S. acus, the middle of the dorsal fin being very nearly the middle of the whole length of the fish ; the series of indu- rated plates between the shoulder and the vent includes eighteen, thence to the end of the tail about thirty-seven ; but both series are liable to a little variation in the number of these sculptured plates : the abdomen is almost rounded ; * Figured by M. Guerin^ in illustration of the genera of the Rtgne Animal, Poissons, plate 65, fig. 1 . 384 the anal fin minute ; the caudal fin pointed ; the two central rays the longest ; the others graduated. The fin-rays in number are — D. 39 : P. 15 : A. 3 : C. 10. The prevailing colour is olive green, mottled and spotted with yellow brown and yellowish white. As mentioned in the account of the Great Pipe-fish, last described, the Deep-nosed Pipe-fish, S. typhle, is well figured in the work of Rondeletius. The vignette below represents the head and tail of this species of larger size than the block of the whole fish would admit. .EQUOREAL PIPE-FISH. 335 LOPHOBRANCHII. SYNGNATH1D&.

Characters. — The species belonging to the second division of the genus Syngnathus have a dorsal fin only ; no pectoral, ventral, anal, or caudal fins j no sub-caudal pouch in either sex. OF this division the British shores produce three species, the largest of which, the .^Equoreal Pipe-fish, was described at length by Colonel Montagu from two specimens obtained on the Devonshire coast. It had been noticed as long ago as 1684 by Sir Robert Sibbald, in his Scotia Illustrata, part ii. book 3, page £4, who attributes to it a length of two feet. Of this species I have not succeeded in taking any exam- ple ; but I possess two, for one of which I am indebted to the kindness of Mr. Embleton, of the Berwickshire Natu- SYNGNATHID.E. ralists1 Club, who obtained it on the coast of that or the adjoining county; and for the other to Mr. Couch. By communication from F. C. Lukis, Esq. I learn also, that this species, which I believe to be rare in England, occurs at Guernsey. I can add but little to the description of Montagu, and shall therefore adopt it, with some slight modifications. " Length twenty inches and a half, viz. ten to the vent, and ten and a half to the end of the tail ;" the length of the head is to the whole length of the fish as one to twelve : " the snout is similar in form to that of S. acus ; its length to the eye three-quarters of an inch ; from thence to the end of the gill-cover, including the eye, one inch : the form of the body is rather compressed and angular, with an acute dorsal and abdominal ridge, which, together with three slight angles on each side, give it an octangular appearance : it is of equal size from the gills to the vent, which part con- tains about thirty plates ; from the vent to the extremity of the tail it is first quadrangular, and towards the end, round and taper, containing about thirty-six plates : imme- diately behind the vent, the body of this specimen suddenly decreases to one-third less in diameter ; but this may be a sexual distinction." " The dorsal fin consists of forty rays, commencing in a vertical line considerably before the vent, and terminating be- hind it, so that three-fourths of the fin is before the ventral aperture. The end of the tail is extremely small and com- pressed, the rays of which are not visible to the naked eye. The colour is yellowish, with transverse pale lines and dark margins, one in each joint, and another down the middle of each plate, giving it the appearance of possessing double the number of joints it really has ; these markings, however, cease at the vent.11 (EQUOREAL PIPE-FISH. 337 Mr. Couch, it appears, lias not seen more than two or three specimens ; but the Cornish fishermen say they find this species from ten to fifteen leagues from land, and in fine weather swimming at the surface over a depth of fifty fathoms or more. My specimens being both females, the sexual peculiarities of this division of the Syngnathi will be explained when describing the next species. The vignette below represents the head and tail of this species on a larger scale. SYNGNATHlD^l. LOPHOBRANCH1I. SYNGNATHIDJE. THE SNAKE PIPE-FISH.

It is immediately distinguishable from the fish last described, with which alone it is likely to be confounded, by its much more slender as well as rounder body, which scarcely exceeds a goose-quill in size, and by the whole of the dorsal fin being, in a specimen of fourteen inches long, more than half an inch before the middle of the fish. Pennant has figured this fish, No. 61 of plate 26, but not described it. In this species, as well as the two others belonging to this second division, neither male nor female possesses an anal pouch, but the ova after exclusion from the abdomen of the female are carried for a time by the male in separate hemi- spheric depressions on the external surface of the abdomen, anterior to the anus. The females have no such depressions. The sexes have been determined by examination of the inter- SNAKE PIPE-FISH. nal structure. All the specimens examined having these ex- ternal hemispheric cells proved to be males, the testes in the abdomen obvious ; those without external depressions proved to be all females, internally provided with two lobes of enlarged ova. The males of this species when taken by me as late in the season as August, had one ovum of the size and colour of a mustard-seed lodged in each cup-shaped cell. These specimens were caught with a keer-drag net between Brownsey Island and South Haven, at the mouth of Poole Harbour. Many specimens of S. acus and typhle were obtained at the same time and place. The length of the head in this species is, compared to the whole length of the fish, as one to eleven ; the form of the body slightly octangular, but more slender and rounded than in that last described ; the body uniform in size as far as the vent, then tapering gradually to the tail, which has a slightly flattened end ; the divisions in the series of transverse plates, and the angles, of the body, almost obsolete ; the dorsal fin, as before mentioned, entirely anterior to the middle of the fish ; the number of rays thirty-eight : the vent in a line with the last fourth portion of the dorsal fin. The colour of the body is a uniform olive green ; the irides red, the pupils black. The specimens I possess vary in length from eight inches to fourteen inches. 340 SYNGNATHID^. LOPHOBRANCHII.

THE WORM-LIKE PIPE-FISH is the smallest of the British species, and is taken on various parts of the coast. Mr. Low describes it as found at Orkney under stones ; and Mr. Couch finds it in similar situations on the coast of Cornwall, where it is considered common. Pennant has figured this species with the ova attached to the under and external surface of the abdomen, as in the species last described. There is little doubt that the young are produced in the same mode as in the other species be- longing to this division of the genus, and that the same sexual peculiarities exist. Pennant, not aware of the singu- lar interchange which takes place, says, very naturally, " On the belly of the female is a long hollow, to which adhere the eggs disposed in three rows.1*' This species does not exceed five inches or five inches and a half in length, and the wood-engraving at the head of the WORM PIPE-FISH. 341 preceding page represents this fish but little less than its natural size. It possesses no fin except that on the back, which in the specimen I examined contained thirty rays. The nose is very short, turned a little upwards ; the eyes pro- minent ; from the point of the jaws to the posterior edge of the orbit, and thence to the end of the operculum, the dis- tances are equal ; the length of these two portions together, compared to the whole length of the fish, is as one to twelve ; the form of the body nearly cylindrical ; the vent is situated at the end of the first third of the whole length, with a series of nineteen plates before it, and in a vertical line, with three-fourths of the dorsal fin behind it ; from the vent the body tapers gradually all the way to the tail, which ends in a point ; the number of plates forming the series between the vent and the tail-end, about fifty. The surface of the body is more smooth than in the two species previously described, and the colour is dark olive green. SYNGNATHID^E. LOPHOBRAXCHII. SYNGNATII1D&. THE SHORT-NOSED HIPPOCAMPUS. Hippocampus brevirostris, CUVIER, Regne An. t. ii. p. 363. Rondeletii, WILLUGHBY, p. 157, I. 25, fig. 3. ,, brevirostris, Sea-horse, JENYNS, Man. Brit. Vert. p. 489, sp. 177. Generic Characters. — The jaws united and tubular, like those of the Syng- nathi ; the mouth placed at the end ; the body compressed, short, and deep ; the whole length of the body and tail divided by longitudinal and transverse ridges, with tubercular points at the angles of intersection ; both sexes have pectoral and dorsal fins ; the females only have an anal fin ; neither sex has ventral or caudal fins. PENNANT, in the edition of his British Zoology, the three first volumes of which were published in 1776 and the fourth in 1777, states that he had been informed the Syng- nathus Hippocampus of Linnaeus, or what the English im- properly call the Sea-horse, had been found on the south- ern shores of this kingdom." John Walcott, Esq. whose MS. History of British Fishes was written in the years 1784 and 1785, says, in reference to a drawing of a female speci- men of what I believe to be the Hippocampus brevirostris of SHORT-NOSED HIPPOCAMPUS. Cuvier, " This was taken on the coast of Hampshire, and given me by the late Mr. Brander." L. W. Dillwyn, Esq. obtained a specimen of Hippocam- pus, some years ago, in Swansea Bay ; and Messrs. C. and J. Paget, in their Sketch of the Natural History of Yar- mouth, state that the Hippocampus is also occasionally met with there. But the most valuable information I have received on this subject has been supplied by F. C. Lukis, Esq. of Guernsey, to whom I am indebted for the loan of the male and female specimens from which the figures at the head of the preced- ing page were taken. By a comparison with M. Guerin's figure of the Hippo- campus brevirostris of Cuvier's Regne Animal, I have little doubt that the two fishes here figured are examples of H. brevirostris ; and Mr. Lukis, in the autumn of 1835, obtained two specimens of Hippocampus on the Hampshire coast, one of which is stated to be identical with those here figured : there can therefore be no doubt, from these various authori- ties, that at least one species is found on our coast, and that this species is also obtained at Guernsey and the other Chan- nel islands. The circumstance of the same species occurring at Guern- sey and on our southern coast, gives additional value to the following communication. At the time of writing, June 9, 1835, Mr. Lukis had two female specimens of Hippocampus brevirostris, then healthy and active, which had been living twelve days in a glass vessel, their actions equally novel and amusing. " An appearance of search for a resting-place induced me," says Mr. Lukis, " to consult their wishes by placing seaweed and straws in the vessel : the desired effect was obtained, and has afforded me much to reflect upon in their habits. They now exhibit many of their peculiarities, 344 SYNGNATHID.*:. and few subjects of the deep have displayed, in prison, more sport or more intelligence." " When swimming about, they maintain a vertical posi- tion ; but the tail is ready to grasp whatever meets it in the water, quickly entwines in any direction round the weeds, and, when fixed, the animal intently watches the surrounding objects, and darts at its prey with great dexterity." " When both approach each other, they often twist their tails together, and struggle to separate or attach themselves to the weeds ; this is done by the under part of their cheeks or chin, which is also used for raising the body when a new spot is wanted for the tail to entwine afresh. The eyes move independently of each other, as in the chamelion ; this, with the brilliant changeable iridiscence about the head, and its blue bands, forcibly remind the observer of that animal." The vignette in illustration of the habits here described was copied from a drawing by Mr. Lukis, most obligingly lent me for this purpose. By the kindness of William Walcott, Esq. I learn that a gentleman of the Island of Jersey, an attentive observer of nature, remembers having more than once seen specimens of Hippocampus curled up in oyster-shells. About four years since, a specimen was shown at Southampton, which lived more than a fortnight in a glass globe. This was said to have been obtained on the French coast near Granville, and was brought to Southampton by one of the sailors of a steam- packet ; I have also heard of one that lived three weeks in confinement at Harwich, the undulating motion of which when swimming was performed with great ease, and was very interesting to observe. The species of Hippocampus in their sexual peculiarities, as far as they have been investigated, appear to coincide with those of the Syngnathi. I had the pleasure of looking over, SHORT-NOSED HIPPOCAMPUS. 845 with Mr. Owen, some specimens in the collection of the Royal College of Surgeons, which had been examined and the internal structure partly exposed to view by the dissec- tions of John Hunter. The females with the abdomen enlarged, as shown in the right-hand figure at the head of this article, have a small anal fin of four rays, but no true pouch ; the ova in the abdomen. Males have no anal fin, in any of the specimens I have examined ; the pouch obvious ; the abdomen smaller than in the females, as shown in the left- hand figure. The two specimens represented in the vignette are both females. Their food is unknown to me, but is probably very similar to that taken by the Syngnathi. The whole length from the point of the nose to the end of the tail is about five inches : the connected jaws, forming a tubular mouth, are considerably shorter than the rest of the head : the eyes prominent, the irides straw yellow ; over each eye a single prominent spinous tubercle : the operculum covered with strise, radiating from the front ; the pectoral fins, placed immediately behind the operculum, are small, appa- rently containing about eight rays in each ; the form of the body heptangular, three angles on each side, the seventh longitudinal angular line being on the abdomen ; the back flat ; the transverse segments of the body eleven, with tuber- cular projections at the points of intersection ; the rays of the dorsal fin about sixteen : the anal fin is peculiar to the female only, and probably performs some office at the time of the transfer of the ova to the pouch of the male ; this anal fin contains four rays : the abdomen as deep again as the tail ; from the vent the form of the tail is quadrangular, end- ing in a point ; the number of segments about thirty. The general colour is a pale ash brown, relieved by a VOL. II. 2 A SYNGNATHTD^. changeable iridiscence, and variable tints of blue dispersed over different parts of the head, body, and tail. I have not included any reference to Linnaeus or Bloch in the synonymes, being doubtful that the species are identical with the one here described. Klein1 s figure, No. 10, very closely resembles the H. brevirostris ; and by the description, the H. antiquus of Risso is also the H. brevirostris of Cuvier. PENNANT S GLOBE-FISH. 347 PLECTOGNATHI.

The skin, over part of the body, armed with numerous short spines. The branchial orifice small. IN this order of fishes, the Plectognathi of Cuvier's ar- rangement, the principal distinctive character consists in the maxillary bones being firmly attached to the intermaxillaries, and both united to the palatine arch. Three examples of this singular-looking fish have been taken in this country, and all three in Cornwall. Pennant first described it as British from a specimen caught at Pen- zance. Mr. Donovan has recorded a second, taken on the 348 GYMNODONTJIKB. Cornish coast, and mentions another obtained in the Euro- pean seas. Still more recently a specimen was taken in Mounts Bay, a drawing of which was sent to the Zoological Society by Dr. Boase, and a notice of its occurrence ap- peared in the Proceedings for October 1888, as referred to. Pennant called his fish Itevigatus in the edition of his work published in 1776, and his editor adopted that of lagocephalus in the edition of 1812, referring to Linnaeus and Bloch ; but the figure of the two specimens by Pennant and Mr. Donovan, and the drawing of the third sent to the Zoological Society by Dr. Boase, agree more closely with the figure of the Globe-fish in Grew's Rarities, tab. 7, and the Orbis lagocephalus of Willughby, plate I. 2, which ap- pear to be intended to represent the same fish, and being without spots or stripes, is, I think, distinct from the lagoce- phalus of Linnaeus and Bloch, the spots of which are referred to in the description of the one, and both spots and stripes shown in the coloured figure of the other. Mr. Donovan, when calling this fish stellatus, appears not to have been aware that this term had been previously appro- priated to an Indian species with black spots ; and still con- sidering this fish provisionally as a new species, I propose for it now the name of our highly-esteemed British zoologist, by whom, as far as I am aware, it was first made known. " The species of this genus are remarkable for being pro- vided with the means of suddenly assuming a globular form by swallowing air, which, passing into the crop or first sto- mach, blows up the whole animal like a balloon. The ab- dominal region being thus rendered the lightest, the body turns over, the stomach being the uppermost part, and the fish floats upon its back, without having the power of direct- ing itself during this state of forced distension. But it is while thus bloated and passive, at the mercy of the waves, PENNANT'S GLOBE-FISH. 349 that this animal is really most secure ; for the numerous spines with which the surface of the body is universally beset are raised and erected by the stretching out of the skin, thus presenting an armed front to the enemy on whatever side he may venture to begin the attack."* Pennant's fish measured one foot seven inches in length ; the belly when distended, one foot ; the whole circumference when in that state, two feet six inches. The form of the body is usually oblong ; but when alarmed, it assumes the shape which has been already referred to. The mouth is small ; the irides white, tinged with red ; the back from head to tail almost straight, or at least very slightly elevated ; there are no ventral fins ; the dorsal fin is placed low on the back ; the anal fin is opposite ; the tail almost even, divided by an angular projection in the middle. The number of fin-rays according to Mr. Donovan — D. 11 : P. 14 : A. 10 : C. 6. The back is of a rich blue colour ; the belly and sides silvery white, studded over with straight spines arising from the centre of four rays ; the fins and tail brown. The spines in Pennant's representation of this fish are not so thickly set as in the figure of Mr. Donovan, or in the drawing by Dr. Boase ; but the space over which they are spread is alike in all three, — that is, bounded superiorly by the lower jaw and the base of the pectoral fin, and posteriorly by the anal aper- ture. * Dr. Iloget.

THE SUN-FISH, as this species has been called from the twofold circumstance of its almost circular form and shining surface, though occurring but occasionally, may be said to have been taken from John o'Groat's to the Land's End. SHORT SUN-FISH. 351 Sir Andrew Balfour and Sir Robert Sibbald have noticed this species in Scotland, and Dr. Neill mentions three ex- amples that were taken in the Frith of Forth. I am in- debted to Edward Jesse, Esq. for a memorandum of one caught on the coast of Northumberland in October 1834. Dawson Turner, Esq. and Mr. Paget have known it to be taken at Yarmouth. I have seen one that was brought to the London market. Colonel Montagu, in his MS. notes, mentions one that was caught at Salcombe in July 1799 : this specimen was of large size, and weighed three hundred pounds. In the fifth volume of Mr, London's Magazine of Natural History, page 315, there is a record of one that was taken at Plymouth ; and Dr. Borlase, Willughby, and Mr. Couch have seen and described examples that were taken on the Cornish coast. Still farther to the westward and north- ward, the Sun-fish has been taken in the Bristol Channel, and one was caught during last summer at Tenby. On the Irish coast, it has been taken at Londonderry; and I am greatly indebted to the kindness of Dr. Arthur Jacob, Pro- fessor of Anatomy in the Royal College of Surgeons in Dub- lin, for his remarks on a specimen taken in the month of August 1826, between the south-west coast of England and Dublin Bay. This paper was published in the Dublin Philosophical Journal for November 1826, and is the best account of this fish that I am acquainted with. When observed in our seas, they have generally appeared as though they were dead or dying, and floating along on one side, presenting the broad surface of the other side to view. Dr. Neill says, of one that was brought to him, " The fishermen informed him, that when they observed it, it was swimming along sideways, with its back-fin frequently above water. It seemed to be a stupid, dull fish : it made little or no attempt to escape, but allowed one of the sailors GYMNODONTIDJS. to put his hands under it, and lift it fairly into the boat. The Sun-fish has been generally mentioned as remarkable for its phosphorescence ; but this specimen did not exhibit that phenomenon so distinctly as a Haddock or a Herring." Pennant repeats Brunnich's account, that between Antibes and Genoa he saw one of this species lie asleep on the sur- face of the water : a sailor jumped overboard and caught it. Mr. Couch says the Short Sun-fish is migratory, keeping probably at the bottom, and feeding on seaweeds in its ordi- nary habits ; but in calm weather it mounts to the surface, and lies, perhaps asleep, with its head and even its eyes above the water, floating with the tide. Mr. Couch has known the Sun-fish make powerful but awkward efforts to escape when attacked, bending and directing its motions in various ways. The figure here given, and the description, are taken from a preserved specimen in the Museum of the Zoological So- ciety. This is the smallest example I have seen. It mea- sures but fourteen inches from the point of the nose to the end of the body ; the breadth of the caudal fin two inches ; the depth of the body eleven inches and a half : the length of the dorsal fin eight inches ; of the anal fin, seven inches and a half: the extension of skin connecting the fin-rays rather thick. The mouth small ; the branchial aperture just in advance of the pectoral fin, small and oval ; the vent just before the anal fin ; the caudal fin occupying the whole space between the anal and dorsal fins, and attached to the pos- terior vertical edge of the body as by a long hinge ; the sur- face of the body in this young specimen but slightly rough- ened, and somewhat wrinkled. The colour of the upper part of the body dusky bluish grey ; the lower part olive brown. The fin-rays in number are — D. 15 : P. 11 : A. 15 : C. 13. SHORT SUN-FISH. 353 The figure at the head of this subject is an exact represen- tation of the fish from which it was taken, differing only in size ; and from some differences that appear in the descrip- tions of specimens of greater bulk, there is reason to believe this fish alters in appearance as it increases in age. In a much larger example the skin was of a uniform dirty pale brown ; the texture hard, rough, coarse, and thick. Accord- ing to Dr. Jacob, the irides in his specimen were dull grey- ish brown, with a silvery ring round the pupil. I am indebted to Mr. Couch for the under jaw-bone of a Sun-fish of considerable size. The outer margin of this bone, for three inches round the front, in which there is no division, is covered to its edge by a narrow band of enamel : the inside, near the centre, contains various dull pearl-like teeth ; some thin and flat, presenting an edge ; behind them others, more cylindrical, short, and rather pointed. Upon the external surface of the head of the example of the Sun-fish taken at Tenby, there were attached about twenty specimens of Tristoma coccineum. Two of these were given to me by H. E. Strickland, Esq. of Cracombe House, Gloucestershire, from one of which. the representa- tions in the vignette below of the upper and under surface were taken of the natural size.

IT has been the opinion of some naturalists that this ob- long Sun-fish is the same species as that last described, and that its greater length in proportion to its depth is but the consequence of greater age. The largest Short Sun-fish of which I have weight and measurement was that taken at Salcombe on the coast of Devonshire. It weighed three hundred pounds, was four feet five inches long, and six feet from the tip of the dorsal fin to the end of the anal fin. This was seen by Colonel Montagu, who was too keen an observer and too good a naturalist not to have detected the difference between the fish he examined and the described OBLONG SUN-FISH. 355 characters of the true mola, if any had existed ; and this fish being probably very old, as well as very large, was the more likely to have assumed the elongated appearance of this se- cond species. The Oblong Sun-fish seems to be much more rare than that last figured. Dr. Borlase appears to be the first and almost the only English writer who has seen and described it. In his Natural History of Cornwall, he speaks of it under the title of the Sun-fish from Mount's Bay, after having described and figured the Short Sun-fish, and mentions that a specimen of this second species was taken at Plymouth in 1734, that weighed five hundred pounds. Mr. Donovan, in his Natural History of British Fishes, says, " We have seen the dried skin of this species, the animal of which, when living, weighed between two and three hundred pounds. Our figure is taken from a small specimen, obtained in a recent state, in one of our fishing excursions on the Bristol Channel. This fish subsists on worms of the testaceous and other tribes, small crabs, &c. fragments of these being found on dissection in the stomach." Mr. Couch, in his MS. says, " I have never met with this fish ; but a fisherman informs me he once took a Sun-fish differing in figure from that with which he was familiar, and which from his description I judge to be this fish. His at- tention was particularly attracted by the curious and beau- tiful waved stripes which it acquired after death, but which he did not observe while it was alive." Never having seen a specimen of this fish, the figure here given is from Mr. Donovan's work, and the description from that of Pennant. " This fish grows to a great bulk ; that which was ex- amined by Salvianus was above a hundred pounds in weight. In form it resembles a Bream, or some deep fish cut off in 356 GYMNODONTID^E. the middle. The mouth is very small, and contains two broad teeth, with sharp edges." " The eyes are little ; before each is a small semilunar aperture : the pectoral fins very small, and placed behind them. The dorsal fin and the anal fin are high, and situated at the extremity of the body ; the tail fin is narrow, and fills all the abrupt space between those two fins." " The colour of the back is dusky, and dappled ; the belly silvery ; between the eyes and the pectoral fins are certain streaks pointing downwards. The skin is free from " When boiled it has been observed to turn into a glu- tinous jelly, resembling boiled starch when cold, and served the purposes of glue, on being tried on paper or leather. The flesh of this fish is uncommonly rank ; it feeds on shell- fish." " There seems to be no satisfactory reason for the old English name. Care must be taken not to confound it with the Sun-fish of the Irish,* which differs in all respects from this." Dr. Turton describes the body of the Oblong Sun-fish to be nearly thrice as long as it is deep : the aperture of the gills semilunar. The fin-rays in number, according to Mr. Donovan, are — D. 12 : P. 14 : A. 15 : C. 17. * The Sun-fish of the Irish coast, particularly on the west coast of Ireland, is the Basking Shark, to be hereafter described, which sometimes attains a length of thirty feet, and is so called from its habit of basking and sunning itself at the surface of the water.

THE only example of this genus which has occurred in the English seas, that I am aware of, was taken off the Sussex coast in the month of August 1827 ; and the circumstance was made known by J. G.

The specimen was exhibited.

The Balistes capriscus is a species well known to the older authors as an inhabitant of the Mediterranean ; is figur- ed by Salvianus ; by Grew, in his Rarities, tab. 7 ; and by Klein, tab. 3. It is, however, rather rare, though stated also to be an inhabitant of other seas. M. Risso says the flesh is tolerably good. Baron Cuvier, in the Regne Animal, in part of the first note at the foot of page 372, says in reference to Balistes capriscus) u Je suis meme tente d'y rapporter le B. buniva de Lacepede." Possessing a dried specimen of B. buniva from the Mediterranean, which agrees exactly with the pub- lished descriptions of that species by Lacepede and M. Risso, I have compared it with the specimen of B. capriscus at the British Museum, and feel confident that the B. bu- niva of Lacepede is, as Cuvier suspected, identical with the B. capriscus of authors. The first and strongest spine of the back in this fish is studded up the front with numerous small projections, which under the microscope have the appearance of so many points of enamel or pearl arising from the surface of the bone, giv- ing a rough denticulated appearance ; and hence the name of File-fish. The second smaller spine has at the anterior part of the base a projection which, when the spines are elevated, locks into a corresponding depression in tlie posterior part of the base of the first spine, and fixes it like part of the work in a gun-lock ; and from this similarity this fish on the Ita- lian shores of the Mediterranean is called Pesce balestra. The longest spine cannot be forced down till the shorter spine has been first depressed. The length from the nose to the branchial orifice is to the whole length of the fish as one to four ; the depth of the EUROPEAN FILE-FISH. 359 body is rather less than half the whole length of the fish, the tail included in both measurements : the body compressed ; the surface hard ; the scales arranged in oblique lines over the whole breadth ; no lateral line observable, except along the middle of the fleshy portion of the tail : the mouth small and narrow ; the visible teeth four on each side the centre above and below, incisor-like or cutting ; the forehead wide between the eyes, which are small, enclosed in well-defined orbits ; the branchial orifice an elongated aperture commen- cing in the front at the base of the pectoral fin, and ascending obliquely backward ; pectoral fin of small size : first spine of the first dorsal fin in a vertical line over the branchial orifice, the second close behind and attached by a strong ligament ; the third spine removed to a distance, but connected by a membrane : the second dorsal fin is high anteriorly and long, commencing in a vertical line before the commencement of the anal fin, but both ending on the same plane, and far short of the base of the caudal rays ; in advance of the anal fin is a strong rough keel, which has some resemblance to ventral fins : the fleshy portion of the tail free, and rather long ; the rays nearly square at the end, large and strong. The fin-rays in number are — D. 3. 28 : P. 15 : A. 26 : C. 14. The colour in the dried specimen is nearly a uniform pale brown ; rather darker on the back ; becoming lighter on the belly, and particularly on the under surface of the head : the naked gums smooth and dark brown. Living specimens are said to be tinged and even spotted with blue ; and it is probable that an individual in this state has furnished the material on which B. maculatus of Bloch is founded : the irides are described as green. The whole length of the Museum specimen is nine inches and a half ; the depth four inches and three-eighths without the dorsal or anal fins. 360 STURIONTD.1S. CHONDROPTERYGII.

ALL the remaining portion of the British Fishes to be yet described belong to Cuvier's division called Chondroptery- giens, or Cartilaginous Fishes, the skeletons of which are made up of cartilage, and not, as in the divisions of Acan- thopterygiens and Malacopterygiens., made up of true bone. The earthy matter in the hard parts of these fishes is smaller in quantity, is deposited in grains, and does not assume the form, as in other fishes, of distinct osseous fibres. In the fishes of the families contained in this order, there are several interesting peculiarities. Some have their gills free, like those of ordinary fishes ; there are others in which the gills are fixed by having their outer edges attached to the * The family of the Sturgeons. COMMON STURGEON. 361 skin. Several of them bring forth their young alive in a manner very different from any of the true bony fishes ; while some, and these the last in the series, want that degree of organization in the bones of the upper jaw observable in those generally which have been hitherto described, but of which two or three examples of deficiency by malformation have been figured. This order may be said to be further distinguished by including within its limits fishes exhibiting in certain points of their structure the highest as well as the lowest degrees of organization observable throughout the whole class. These different peculiarities will be pointed out on arriving at the different genera in succession. The Sturgeon, the first of the cartilaginous fishes, allied to the Sharks in the elongated form of its body, resembles other fishes in having the gills free, and in being oviparous. It is caught occasionally on various parts of our coast, most frequently in the estuaries, or but a short distance up rivers ; very seldom taken in the open sea, where it is believed to inhabit deep water, beyond the reach of nets, and is not, that I am aware, ever caught upon the fishermen's lines. Dr. Neill says that one or two are generally taken every summer about the mouth of the Almond or of the Esk, where they get entangled in the Salmon nets, and when of large size frequently doing the fishermen considerable damage by tearing their nets. They are otherwise harmless. One caught in a stake net near Findhorn in Scotland in July 1833, measured eight feet six inches in length, and weighed two hundred and three pounds. The Sturgeon is occasionally taken on the East coast, and frequently brought to the London market from various loca- lities. When caught in the Thames, within the jurisdic- tion of the Lord Mayor, it is considered a Royal Fish ; VOL. II. 2 B the term being intended to imply that it ought to be sent to the King, and it is said that the Sturgeon was exclusively reserved for the table of Henry the First of England. On our Southern coast, Colonel Montagu mentions one taken in the estuary at Kingsbridge ; and Mr. Couch enu- merates three instances at different periods of different years; one in the Tamar in June, one at Plymouth in August, and one near the Eddystone in January. In September 180£, a specimen, eight feet long, and weighing one hundred and ninety-two pounds, was caught in a weir below the castle at Shrewsbury. The largest specimen taken in this country is probably the fish recorded by Pennant, which was caught in the Esk, and weighed four hundred and sixty pounds. In Ireland the Sturgeon has been taken on the south, the east, and the north coasts. In the northern parts of Europe this fish is much more numerous than with us, and extensive fisheries are establish- ed for its destruction. Caviar is made of the roe of the female ; isinglass is obtained from the dense membrane form- ing the air-bladder ; and the flesh, besides being preserved by salting and pickling, is in request for the table while fresh, being generally stewed with rich gravy, and the flavour considered to be like that of veal. The "flesh, like that of most of the cartilaginous fishes, is more firm and compact than is usual among those of the osseous families. The Sturgeon, as has been before observed, is oviparous, spawning in winter. It has been frequently remarked that Sturgeons of very small size are seldom seen : by the kindness of Mr. George Daniell, however, I possess a small specimen, only twelve inches long, that is quite perfect, and exhibits all the characters of the mature fish. " It is presumed that the young, as soon as they escape from the eggs, which the female deposits in fresh water, descend immediately to the sea, and do not visit the places of their birth again till they COMMON STURGEON. 368 come in their turn to deposit their spawn." The Sturgeon is said to subsist on small fishes ; from the structure of the mouth it probably feeds also on any soft substance that it finds at the bottom. The body is elongated ; from the shoulders backward somewhat pentagonal in shape, with five longitudinal rows of flattened plates, with pointed central spines directed back- wards,— one row, larger than the others, along the ridge of the back, one row on each side, and another along the edge of the abdomen in a line from the pectoral fin to the ven- tral on each side ; the flattened plates are marked with ra- diating strise. The nose is long and pointed ; the forehead with a longitudinal depression ; the crown of the head ele- vated, the occiput rising into a sharp keel : the mouth placed on the under surface of the head, rather wider than long, with a projecting rim ; no teeth within : about half-way between the mouth and the end of the nose, are four cirri ranged in a line across ; the eyes small ; the operculum hard and strong, covered with strise radiating from a centre ; dorsal fin placed very far back, but little in advance of the line of the anal fin : tail forked ; upper lobe much the long- est, and pointed. The fin-rays in number — D. 35 : P. 28 : V. 24 : A. 23 : C. 125. The colours of the body are various shades of brown ; the plates nearly white, the belly silvery.

THIS fish has considerable resemblance to the Sharks in the form of the body, and the position as well as the shape of the fins. " The Chimserse," says Dr. Richardson,* " though placed by Cuvier at the end of the Sturionid^ seem to belong more properly to his second order of Chondropterygii, in which the gills are fixed : for though there is only one appa- rent gill-opening on each side, the gills in reality adhere by a large part of their borders, and there are consequently five * Fauna Boreali-Americana, part iii. Fishes, page 285. NORTHERN CHIMERA. 365 holes communicating with the external gill-opening. They have a rudimentary operculum concealed by the skin ; and their jaws, still more reduced than those of the Sharks, are furnished with hard plates, four above and two below, in place of teeth. The males are distinguished by trifid bony appendages to the ventral fins, and produce very large lea- thery eggs, having flat velvety edges." The Northern Chimsera is represented as a fish of singular appearance and beauty, a native of the northern seas only, where it seldom exceeds three feet in length, and is generally taken when in pursuit of shoals of Herrings, or other small roving fishes, upon which it principally subsists : Bloch says it feeds also on medusae and Crustacea. The flesh is de- scribed as hard and coarse. According to some authors, the Norwegians extract an oil from the liver which they consider of singular efficacy in disorders of the eyes. Pennant received from a gentleman a drawing and particu- lars of one that had been taken among the Shetland Islands : this species was also known to Dr. Walker as an occasional visitor in that locality. Never having seen this fish, I avail myself of Dr. Fleming's description, taken from a specimen sent by L. Edmonston, Esq. from Unst, where it is termed the Rabbit-fish. A specimen taken from the same locality has lately been received by Mr. W. C. Hewitson of New- castle, the author of a valuable work on the eggs of British Birds. " Length nearly three feet. Body compressed. Head blunt ; the snout sub-ascending, blunt. A narrow crenulated grinder on each side in the lower jaw, and a broad tubercular one corresponding above. Nostrils immediately above the upper lip contiguous, each with a cartilaginous complicated valve. Branchial openings in front of the pectorals. Eyes large, lateral. On the crown, in front of the eyes, a thin 366 osseous plate, bent forwards, with a spinous disc at the ex- tremity on the lower side. Lateral line connected with nu- merous waved anastomosing grooves on the cheeks and face. The first dorsal fin above the pectorals narrow, with a strong spine along the anterior edge. The second dorsal rises im- mediately behind the first, is narrow, and is continued to the caudal one, where it terminates suddenly. The pectorals are large, and subtriangular. Ventrals rounded ; in front of each a broad recurved osseous plate, with recurved spines on the ventral edge. Claspers pedunculated, divided into three linear segments ; the anteal one simple, the retral ones hav- ing the opposite edges covered with numerous small reflected spines. A small anal fin opposite the extremity of the se- cond dorsal. Caudal fin above and below, broadest near the origin, gradually decreasing to a linear produced thread." The representation here given was taken from the figure in Mr. Donovan's work ; and being that of a female fish, does not show the claspers described by Dr. Fleming as existing in his specimen, which was a male. These sexual and other peculiarities will be pointed out when describing other spe- cies of Sharks ; which being of much more frequent occur- rence, have afforded opportunities for more detailed observa- tions. The appendage on the front of the head in this fish is pe- culiar to the males only, and has given rise to the name of King-fish, applied to it by the Norwegians ; who also call it Gold and Silver Fish, in reference to its beautiful colours: these are various shades of rich brown on a shining white ground. The eyes are large and brilliant ; the pupils green, the irides white. This fish was first made known by Gesner. SMALL-SPOTTED DOG-FISH. 367 CHONDROPTERYGJI. SQUALID& THE SMALL-SPOTTED DOG-FISH.

THE true Sharks, as previously stated, have their gills fixed, their margins being attached ; the water escaping by five elongated branchial apertures, the form and position of which, in conjunction with modifications observed in the fins and other parts, furnish characters by which the different divisions forming this family are distinguished. Among the * The family of the Sharks. 368 SQUALID.E. Sharks, the males differ from the females externally in having an elongated cylindrical appendage at the inner edge of each ventral fin, the uses of which are not understood. The third species of Scyllium here figured represents a male fish, and shows the peculiarity of the ventral fins in that sex. The females are not furnished with these appendages : the figures of the first two species represent females, and the vignettes to each show on an enlarged scale the specific and sexual peculiarities of the ventral fins, and also the difference in the form of the mouth in these two species. Of the true Sharks, some produce their young alive, and are called viviparous ; others, like those under present consi- sideration, bring forth their young enclosed in horny cases, an example of which is here introduced, a portion of one side of the case being removed to show the young fish within. On examining adult females, the ova are observed in differ- ent stages of growth descending from the ovaries, usually in pairs, frequently one in each oviduct, becoming enclosed in the protecting covering when about to be excluded. These cases, which are frequently found on the sea-shore, and are called Mermaid's purses, sailor's purses, sea purses, &c. are oblong, of a pale yellowish horny colour, semitransparent, with an elongated tendril at each of the four corners : these are deposited by the parent Shark near the shore in the win- SMALL-SPOTTED DOG-FISH. 369 ter months. The convoluted tendrils hanging to sea-weed or other fixed bodies prevent the cases being washed away into deep water. Two elongated fissures, one at each end, allow the admission of sea-water ; and the young fish ulti- mately escapes by an opening at the end, near which the head is situated. For a short time the young Shark conti- nues to be nourished by the vitelline fluid contained in the capsule attached to its body by the connecting pedicle, till, having acquired the power of taking food by the mouth, the remains of the ovum are taken up within the abdomen, as in birds and some other animals. A curious peculiarity has been observed in the young of both Sharks and Skate during a very early stage of their ex- istence. From each of the branchial apertures, branchial fila- ments project externally : each filament contains a single minute reflected vessel, in which the blood is thus submitted to the action of the surrounding medium. These appen- dages are only temporary, and the blood of the fish is after- wards aerated by the true gills. This very interesting disco- very, which I believe is of recent date, forcibly reminding us of the temporary external branchiae in the young of Batra- chian reptiles in the tadpole state, has been observed by Mr. Richard Owen in the Blue Shark, Carcharius glaucus, by Dr. John Davy in the Torpedo, and by Dr. Allen Thomp- son of Edinburgh in the Thornback. Cuvier had previously noticed it, and in the Regne Animal has referred to a figure published by Schneider of a very young Shark in this condi- tion, for which, regarding it as the normal state of this fish, that industrious pupil of Bloch had proposed the name of Squalus ciliaris. Among the Sharks, as among the truly predacious birds, the females are larger than the males ; and almost all the spe- cies have received some name resembling Beagle, Hound, 370 SQUALID^. Rough Hound, Smooth Hound, Dog-fish, Spotted Dog, Penny Dog, &c. probably from their habit of following their prey or hunting in company or packs. All the Sharks are exceedingly tenacious of life. Their skins, of very variable degrees of roughness, according to the species, are used for different purposes ; in some instances by cabinet-makers, for bringing up and smoothing the surfaces of hard wood. The two British species of Spotted Sharks appear to have been frequently confounded with each other. The terms Greater and Lesser seem sometimes to have been considered as referring to the size of the spots, and at others to the size of the fish. A slight alteration in the names, which is here suggested, will assist in defining the two species, and other decided specific distinctions will be pointed out. Both spe- cies are called Roussette by the French, on account of their prevailing reddish brown colour. The Small-spotted Dog-fish, the subject of the present notice, is one of the most common species on our shores, particularly along the Southern coast. Its station in the water is near the bottom ; its food, small fish and Crustacea. It takes a bait freely, and is often caught on the fishermen's lines, but is a useless capture to them. It is troublesome and annoying from its numbers, and injurious to the fisheries from its voracity. The teeth of the Sharks are very formidable weapons, ge- nerally constructed decidedly either for cutting or holding. The representation here introduced shows on the left hand SMALL-SPOTTED DOG-FISH. 371 two teeth formed for cutting; these are flattened, thin, sharp, and serrated on both edges ; the teeth represented belong to the left of the centre when viewed in front. The two teeth on the right hand are formed for holding, being generally curved inwards, and provided with a small lateral tubercle at the base on each side. The teeth of the Sharks belonging to the genus Scyllium, now under consideration, are of this last form, but smaller, depending on the size of the fish. The outside tooth in the front row of each jaw in the Sharks is supported on the inside by various other teeth, which sup- ply deficiencies as necessity may require. The specimen from which the description was taken mea- sured eighteen inches in length ; the body, from the base of the pectoral fins, where it is thickest, tapering all the way to the end of the tail. The head is flattened on the top ; the eyes large ; the orbits elongated, with a distinct aperture behind each ; the form of the under surface of the nose, the nostrils, and upper lip, as shown in the left-hand figure of the vignette at the end ; the mouth in the form of a horse- shoe, the extreme angles only being directed outwards ; the teeth numerous, small, pointed, and sharp, like those on the right hand in the representations of Shark's teeth, but very minute ; the pectoral fins large : the branchial apertures on the sides of the neck elongated vertically, five in number, the first rather the largest, the last the smallest ; the fourth aper- ture over the anterior edge of the pectoral fin : the ventral fins united almost to the posterior extremity in the males, less completely united in females ; the elongated anal aper- ture in the middle between them : the outer posterior mar- gins, in both sexes, are as oblique as those of the front : the right-hand figure of the vignette at the end shows the lozenge- shape of the fins when seen from below. The first dorsal fin is over the space between the ventral and anal fins, and occu- 372 SQUALID^. pies nearly the middle of the whole length of the fish ; the anal fin is under the space between the first and second dorsal fins ; the posterior edge of the second dorsal fin half-way between the commencement of the first dorsal fin and the end of the tail ; the vertebral portion of the tail nearly in a line with the body, with a narrow elongated membranous ex- pansion above it, and one long and one short triangular ex- pansion below it. All the upper part of the body marked with numerous small, dark, reddish brown spots, on a pale reddish ground ; the spots on the fins rather larger and less numerous than those on the body ; the lower part of the sides and the under surface yellowish white. The skin, to the finger passed from the head towards the tail, is smooth ; in the opposite direction it is rough. The appearance of the skin under a lens is that of being covered with minute spi- culae, all the points of which are directed backwards. LARGE-SPOTTED DOG-FISH. 373 CHOKDROPTER YOU. SQUALIDM.

Mr. Jenyns, in his valuable Manual of British Vertebrate Animals, has so clearly pointed out the specific distinctions of this fish, from examples obtained at Weymouth, that, having no specimen, this Shark being by much the more rare 374 SQ.UALID.E. of the two, I avail myself, by permission, of the comparative description therein given. " Length from two to three feet. According to M. Blainville, this species attains to a larger size than the last. Differs essentially from S. canicula in the structure of the lobes of the nostrils, and in the form of the ventrals:* the former are not united as in that species, and of a smaller size, leaving the whole of the mouth and the upper lip visi- ble : the ventrals, instead of being cut obliquely, are cut nearly square, their posterior margins meeting at a very ob- tuse angle ; they are united or separate according to the sex, in a similar manner : the snout is rather more elongated ; and, according to some authors, the tail rather shorter, giving the dorsal a more backward position ; but this last character I have not noticed myself. Upper parts brownish grey, with very little of the red tinge observable in the last species : back, flanks, and tail, sparingly marked with large spots of a deep brown or black colour : under parts whitish." * See the vignettes of the nostrils and the ventral fins of both species.

Its length was twenty-five inches and three-quarters, and seven inches round where stoutest. The head flat on the top, rather wide posteriorly ; snout thin, protruded one inch and three-quarters from the ante- rior angle of the eye ; nostrils one inch and a quarter from the snout, double, one beneath linear, the other on the mar- gin, the hinder edge prominent, a depression in the head im- mediately above it ; eye rather large, oval, close behind it a moderately sized temporal orifice; mouth one inch and three- quarters wide ; teeth numerous, small, sharp, at each side of the base of each tooth a small sharp process ; spiracles five, 376 SQUALID^:. open ; the back somewhat elevated close behind the head ; the skin rough against the grain ; pectoral fins wide, much like those of the Picked Dog : the first dorsal begins at twelve inches from the snout, and behind the ventral fins ; the second at sixteen inches and a half, both rather small : ventrals ten inches from the snout ; anal fin four inches long, rather narrow, terminating just opposite the end of the second dorsal : extreme length of the tail seven inches ; the upper lobe in a line with the body, bent down towards the termina- tion, rounded, incised, or jagged ; under lobe rather narrow in its course, expanded beneath ; the upper ridge of the su- perior lobe has a double row of prickles pointing outward and downward on each side ; lateral line suddenly bent opposite the origin of the caudal fin. Colour, a light brown on the head and along the back : on each side two rows of ocellated spots ; one row beginning at the side of the neck, and con- tinued along the side of the back ; the second row commen- cing behind the eye and passing along the upper side of the belly, becoming obsolete near the ventral fins ; these rows are separated by numerous irregular spots, which, however, as- sume somewhat of a straight direction ; the fins and hinder part of the back are finely barred and clouded with various tints of brown and yellow ; the mouth dark-coloured within. This species is well known in the Mediterranean. Mr. CouclTs specimen was that of a male, and the figure is taken from a drawing lent for that purpose.

THIS species has been noticed by several English authors, but apparently not from specimens which had been examined by them personally. Low says that, according to information given him, it is sometimes met with among the Orkney Is- lands. Grew, in his Rarities of Gresham College, page 90, states that they are sometimes found upon our own coast near Cornwall. As it appears to be well known in the Me- diterranean, and to be a great wanderer, the Cornish coast is a very probable locality, and it, or the fish figured in the vignette, may prove to be the Rashleigh Shark of Mr. Couch. This fish acquires a large size, and with another species, not very dissimilar in shape and equally powerful, are the terror of mariners in most of the warm countries of the globe. VOL. ii. 2 c 378 SQUAL1DJE. It swims with great ease and swiftness from the large size of its pectoral fins ; and when caught with a baited hook at sea, and drawn upon deck, the sailors1 first act is to chop off its tail to prevent the mischief otherwise to be apprehended from its great strength. Cuvier, in the Regne Animal, says the only good figure of this fish is that in Belon, page 60 ; and having no access to a specimen, that figure has been carefully copied, and the fol- lowing description is from M. Risso. The body is elongated, covered with a hard skin, ash brown above and whitish below. The head is large ; the muzzle depressed, short, and pierced with numerous pores : the mouth is large and wide ; the tongue short and rough : the upper jaw furnished with six rows of triangular teeth, thin, nearly straight at the edges, and serrated ; in the under jaw four rows, sharper than those above, but less com- pressed : the irides are pearl white ; pectoral fins very large ; the first dorsal fin elevated ; the ventral fins small ; the anal fin is opposed to the second dorsal ; the tail is divided, form- ing two lobes, of which the upper lobe is the longest. It is most frequently seen in the Mediterranean during spring and autumn. The vignette represents another species, which has also been called White Shark, and may assist observers on the coast.

THIS species is occasionally met with on the British coast: Pennant examined one that measured thirteen feet in length ; and specimens have been seen of fifteen feet long. It is called the Sea-Fox from the length and size of its tail ; and, according to Dr. Borlase, has received the name of Thresher from its habit of attacking other animals, or defending itself, by blows of the tail.* It is an inhabitant of the Mediterra- nean, as well as other seas ; and a specimen has been taken near Belfast. The extreme length of a specimen examined by Mr. Couch, " was in a straight line ten feet ten inches, and along the curve eleven feet eight inches ; three feet four inches round where thickest ; solid at the chest ; conical from the * See vol. i. page 144. 2 C 2 380 SQ.UALID.E. snout to the pectoral fins, and thick even to the tail, which organ from the root was five feet and a half long, and conse- quently more than half the length of the body ; eye promi- nent, round, hard, four inches from the snout ; iris blue, pupil green : the nostrils small, and not lobed ; mouth five inches wide, shaped like an horse-shoe ; teeth flat, triangular, in two or three rows, not numerous ; spiracles five ; pectoral fins wide at the base, pointed, eighteen inches and a half long. Measured along the curve, from the snout to the first dorsal fin, was two feet five inches, the fin triangular ; from the first dorsal to the second, fourteen inches and a half; this and the anal fin small ; ventral fins also rather small, triangu- lar ; above and below at the base of the tail a deep depres- sion ; skin smooth ; lateral line central and straight ; breadth of the tail, including both lobes, thirteen inches ; the upper lobe narrow throughout its great length, and on the lower margin, at four inches from the extremity, is a triangular process. Colour of the body and fins dark blue, mottled with white over the belly." Mr. Couch says it is not uncommon for a Thresher to approach an herd of Dolphins (Delphini) that may be sport- ing in unsuspicious security, and by one splash of its tail on the water put them all to flight like so many hares before a hound. " The specimen here described was taken at the entrance of the harbour of Looe in Cornwall, in October 1826, hav- ing become entangled in a net set for Salmon. The mouth seemed more feeble than in most of its genus, which is rendered more probable by the circumstances of its cap- ture ; for the Blue Shark (next to be described) would in an instant have cut its way through an obstruction that proved fatal to the Thresher. The stomach was filled with young Herrings." BLUE SHARK. 381 CHONDEOPTERYGII. SQ.UAUDJE. THE BLUE SHARK. Carcharias glaucus, Le Bleu, CUVIER, Regne An. 1. ii. p. 388.

THE affection of the Blue Shark for its young was the theme of several of the older writers, ichthyologists as well as poets; and mariners of the present day believe that, when dan- ger appears, the young brood enter the mouth of the parent fish, and take shelter in its belly. Living young have doubt- less been found in the stomachs of large Sharks : their extra- ordinary tenacity of life is proverbial, and will account for this ; but the safety to be expected from incarceration in such a prison is somewhat problematical. The Blue Shark is an inhabitant of the Mediterranean, and appears to occur much more frequently on the Devon- shire and Cornish coasts than on any other part of the British Islands ; it has also been taken off the south coast of Ireland, and has been known to wander even as far north as Zetland. Mr. Couch, who has had frequent opportunities of seeing this species, makes the following observations : — " The Blue 382 SQUALID.E. Shark is migratory, and I have never known it arrive on the coast of Cornwall before the middle of June ; but afterwards it becomes abundant, so that I have known eleven taken in one boat, and nine in another, in one day. The injury they inflict on the fishermen is great, as they hover about the boats, watch the lines, (which they sometimes cut asunder without any obvious motive,) and pursue the fish that are drawn up. This, indeed, often leads to their own destruc- tion : but when their teeth do not deliver them from their difficulty, they have a singular method of proceeding, which is by rolling the body round so as to twine the line about them throughout its whole length ; and sometimes this is done in such a complicated manner, that I have known a fisherman give up any attempt to unroll it as a hopeless task. To the Pilchard drift-net this Shark is a still more dangerous enemy, and it is common for it to pass in succession along the whole length of the net, cutting out, as with shears, the fish and the net that holds them, and swallowing both together." The specimen described measured fourteen inches ; the head depressed, broadest between the eyes, which are lateral ; half-way between the eyes and the point of the nose are the nos- trils, linear, directed obliquely downwards and backwards, the most inferior portion covered with a valvular fold of skin ; the eyes round and rather large ; the mouth forming half a circle, the teeth in this specimen very minute, — the cutting teeth on the left hand in the representation at page 370 belong to this species, and were from a specimen about six feet in length., in each jaw of which there are three rows, those im- mediately in the centre, to the number of four, being calcu- lated more for holding than cutting ; the number of rows of teeth in the Sharks are said, and I believe correctly, to in- crease with age, and vary in this species from one to six. The branchial apertures are five, the fourth placed over the BLUE SHARK. 383 line of the anterior edge of the pectoral fin ; the pectoral fins large and falciform ; the body of the fish deepest in the line of their origin, but becoming more compressed and tapering from thence to the tail ; the first dorsal fin situated over the space between the pectoral and anal fins, rather small, low and rounded above, with a horizontal projecting elongation at the base behind : the ventral fins small, obliquely truncat- ed, and placed under the space between the first and second dorsal fins ; the anal fin placed half-way between the ventral fins and the lower lobe of the tail, opposed to or under the second dorsal fin, and each ending in a prolongation directed backwards ; the tail divided, the upper lobe two- thirds longer than the lower, the vertebral column continued along it ; the inferior lobe somewhat triangular in shape ; the upper lobe falciform, and with an extension of the membrane towards the extreme end. The whole of the upper surface of the head, back, both dorsal fins, and most of the tail, are of a fine slate blue ; the irides, upper surface of the pectoral and ventral fins, are also blue ; the lower part of the sides, under surface of the head, neck, pectoral fins, belly, ventral fins, and the anal fin to the base of the tail, white. The skin of this Shark has a granu- lated appearance on the surface, and is only slightly rough to the touch on passing the finger in the direction from the tail towards the head.

THE PORBEAGLE occurs more frequently on the northern than on the southern coasts of this country, and is mentioned as having been taken at Belfast. The specimen described and figured by Dr. Goodenough in the Transactions of the Linnean Society, as quoted, was taken at Hastings ; Mr. Couch has seen it occasionally in Cornwall, and it was figured by Dr. Borlase in his history of that coast. Mr. Couch states of this species, " That it associates in small companies in pursuit of prey, from which circumstance, and a distant PORBEAGLE. 385 resemblance to the Porpus, they derive their name. I have found the remains of cartilaginous fishes and Cuttles in their stomachs, and in one instance three full-grown Hakes. This species attains a large size at an early age, so that I have found it cutting its second row of teeth when nearly full- grown." On the northern and north-east coast it occurs most fre- quently during autumn, and, not to multiply descriptions already in print, I shall here insert one furnished by Dr. George Johnston of Berwick, who examined two specimens in the autumn of 1834, both of which were taken in Ber- wick Bay, and who also very kindly sent me, with his de- scription, a portion of a jaw, from which the teeth on the right hand at page 370 were drawn. Of these teeth there were three rows, the third or inner row being much smaller than the teeth of the two preceding rows, and perhaps only recently exposed. Body fusiform, very narrow at the tail, and strongly keel- ed there on each side ; skin smooth when stroked backwards, of a uniform greyish black colour, the belly white : snout obtusely pointed, with a band of punctures on each side of the forehead terminating above the eyes, a few similar punc- tures behind the eyes, and a triangular patch of them before the nostrils ; they are the apertures of canals filled with a transparent jelly : eyes round, dark blue ; branchial slits five, cut across the neck, the posterior oblique and close to the pectoral fin ; back rounded ; dorsal fin triangular, with a free pointed pale-coloured process behind ; posterior dorsal fin also pointed posteriorly ; pectorals somewhat triangular, obliquely sinuate on the posterior edge, black ; ventral fins rhomboidal, meeting at the mesial line, on which are the anal and generative apertures ; anal fin small, pointed be- hind : tail lunate, with unequal lobes, the superior and larg- 386 SQUALID,*:. est with a projecting outline near the tip ; above the tail there is a flat space bounded by a short transverse ridge, and a similar one opposite on the ventral side : lateral line straight ; the keel on the body runs forward on the tail, and there is a small keel beneath this confined to the tail itself. The length along the lateral line, five feet eight inches and a half; circumference in front of the dorsal fin, two feet eight inches and a half; from the snout to the eye, four inches and three-quarters ; diameter of the eye, one inch and one-tenth : breadth between the eyes, five inches and one-quarter ; from the snout to the margin of the upper lip, four inches and a half, thence to the angle of the mouth also four inches and a half; breadth of the mouth from angle to angle, eight inches and one-quarter ; from the snout to the first gill-aperture, one foot three inches ; snout to pectoral fin, one foot six inches and a half ; length of pectoral fin, one foot one inch ; breadth of pectoral fin, six inches and a half; snout to dorsal fin, two feet one inch and three-quarters ; height of dorsal fin, nine inches and three-quarters ; length of dorsal fin, ten inches and one-quarter ; length of the free portion of it, three inches ; space between the first and second dorsal fins, one foot eight inches ; length from the snout to the anal aperture, three feet eight inches ; extreme breadth of the tail, one foot eight inches ; length of the tail in the mesial line, six inches and one quarter.

BARON CUVIER, in his Regne Animal, as above quoted, considers the Monensis of Shaw and Pennant distinct from the Cornubicus last described, on account of its shorter muz- zle and sharper teeth ; to this may be added that the eye is much larger, the pectoral and dorsal fins are placed farther back on the body, and the bulk of the fish is greater in pro- portion to its length. The editor of the last edition of Pen- nanfs British Zoology, published in 1812, possessing at that time the original drawing of the Rev. Hugh Davies of Beaumaris, has borne testimony to the correctness of Pen- nant's figure of this fish, which had been questioned ; and the Beaumaris Shark is therefore considered, provisionally, as a distinct species. Two specimens, the only examples known, having both occurred on the Anglesey side of the Menai, confirm the 388 SQUALID^:. propriety of the terms Beaumaris Shark and Monensis, by which this fish is known. Some particulars of both exam- ples are here added from Pennant. " The first specimen obtained was seven feet long ; the snout and body of a cylindrical form ; the greatest circumfer- ence four feet eight inches ; the nose blunt ; the nostrils small ; the mouth armed with three rows of slender teeth, flatted on each side, very sharp, and furnished at the base with two sharp processes ; the teeth are fixed to the jaws by certain muscles, and are liable to be raised or depressed at pleasure. The first dorsal fin was two feet eight inches dis- tant from the snout, of a triangular form ; the second very small, and placed near the tail ; the pectoral fins strong and large ; the ventral and anal small ; the space between the second dorsal fin and the tail much depressed, the sides forming an acute angle ; above and below was a transverse fossule or dent. The tail was in the form of a crescent, but the horns of unequal length ; the upper, one foot ten inches; the lower, one foot one inch. The whole fish was of a lead colour. The skin comparatively smooth, being far less rough than that of the lesser species of this genus." " The second example was nine feet six inches in length, that is, two feet and a half longer than the first, but each part of this bore an exact proportion to the corresponding parts of the other ; except that the nose of this, although above one-third a larger animal than the former, was smaller in every respect, being more abruptly tapering, but blunt and shorter, as it measured but four inches and eight-tenths from the eye to the end, whereas the snout of the smaller fish was six inches in length from the end to the eye. This was a vast animal ; its general circumference seemed greater in pro- portion to its length, than that of the former, but it was par- ticularly so at the region of the abdomen. This is readily BEAUMARTS SHARK. 389 accounted for, when we say that it was a female, and had in its belly four young ones, each about eight-and-twenty or thirty inches long. Seventeen quarts of oil were obtained from the liver. As it is supposed, with reason, that in this tribe of ferocious animals, the female is invariably the largest, I am induced to conclude, that the specimen which I observ- ed near forty years ago, might have been a full-grown male, and that the difference between the two sexes is inferiority of size with regard to the male, but with a front in every re- spect larger than that of a female." " In the third volume of the late edition of Mr. Pen- nants Tour in Wales, the Rev. Hugh Davies has furnished some further observations on the Beaumaris Shark, and a comparative outline is given of that species and of the Por- beagle Shark." The latter species appears to be by much the more com- mon fish of the two. The vignette represents the sort of hand-line used at sea on the Hampshire coast for Mackerel and Whiting fishing, and is usually called the Portsmouth pattern. 390 SCiUALlD.E. CHONDROPTERYGll.

THE TOPE is a common species along the southern coast, where it is known by the names of Penny Dog and Miller's Dog ; it has also been noticed by Pennant in Flint- shire ; and by others on the south coast of Ireland, about the shore of the county of Kerry. It is not, however, considered so plentiful in the north, but has been taken about Berwick Bay, and its occurrence recorded by Dr. Johnston in his address to the Members of the Berwickshire Natural History Club for the year 1882. COMMON TOPE. 391 On the Cornish coast this is a common and rapacious species ; but it is not so destructive as the Blue Shark. The larger specimens, which are about six feet long, abound chiefly in summer ; and the young, to the number of thirty or more, according to Mr. Couch, are excluded all at once from the female in May and June. They do not reach the full size until the second year, and continue with us through the first winter, while those of larger size retire into deep water. No use is made of this fish beyond melting the liver for oil. When caught on a fisherman's line, this fish sometimes has recourse to the same attempt at deli- verance as the Blue Shark, by twisting the line throughout the whole length round its body. Body fusiform ; the skin almost smooth ; lateral line straight ; the first and second dorsal fins rather small, tri- angular, very slightly convex on their posterior edges, both ending in points directed backwards ; the first dorsal fin placed over the interval between the pectoral and ventral fins ; the second immediately over the anal fin, and a little larger in size : the head is rather large ; the muzzle elon- gated and depressed ; nostrils pierced very near the mouth, in part closed by a membrane ; the eyes moderate, and over the mouth ; temporal orifices small ; the jaws semicircular ; teeth small, in several rows, and very nearly alike both above and below, triangular and denticulated on the outer side ; the branchial apertures are small, placed near together, the four first nearly equal in size, the fifth the smallest, and placed over the anterior edge of the pectoral fins ; the pec- toral fins are of moderate size, and triangular in shape ; the ventral fins small, near the middle of the whole length, and under the space between the first and second dorsal ; the tail rather less than half the length of the body, with a bi-lobed fin ; the upper lobe terminal, oblique, and truncated; 392 SQUALID.E. the inferior lobe with one deep triangular elongation, and a smaller one near the end. All the upper part of the body and sides are of a uniform slate grey, the under surface lighter in colour, inclining to greyish white. The vignette represents a boat of the Lake of Geneva.

Generic Characters. — The same as in the last genus, Galeus, except the pointed teeth, which in this are flat, like those of the Skate. THIS Shark is rather a common species round our coast. It is occasionally taken in the Frith of Forth ; and Dr. Flem- ing says the flesh of it is used as food in the Hebrides, and is esteemed a delicate dish. I have received this Shark from Dr. Johnston of Berwick, and have seen it at various places on the coasts of Kent and Sussex. It is called Smooth Hound, from the comparative softness of its skin in reference to British Sharks in general ; and it is also called Ray- mouthed Dog in Cornwall, from the form of its teeth, which are flat and without prominent points, like those of the fe- male or young male of the Thornback. The vignette repre- sents an inside and an outside view of one half of the mouth and teeth of this Shark, which are so different from those of VOL. II. 2 D 894 SQUALID.E. any other British Shark as to serve the purpose of a distin- guishing character. The peculiarity in the form and arrange- ment of these teeth, so closely resembling those of the Skate, is seen by comparing the vignette before referred to with that representing the teeth of the Thornback, which is given hereafter, when describing the first species of true Skate. The young of the Smooth Hound frequently have nume- rous small white spots above the lateral line ; but the teeth and other characters agree so closely with the spotless grey examples of larger size, that I am induced to consider these spots only as marks of youth, which may also be observed in other species, particularly in the Picked Dog-fish, Spinax Acanthias, Cuvier : and in this view I am further confirmed by the opinions of Mr. Couch and Dr. Johnston. Mr. Couch says of this species, in reference to its habits, that it is common, but not abundant, and keeps close to the bottom on clean ground, where it feeds on crustaceous ani- mals, which it crushes previous to swallowing, and for which its flat pavement-like teeth are well adapted : it also takes a bait, but is less rapacious than most of the tribe. The young are produced alive in November, the whole coming to perfec- tion at once ; but they are few in number, not perhaps ex- ceeding a dozen, and soon after birth they all go into deep water, from which they do not emerge until the following May. This species has been taken on the coasts of the counties of Antrim and Londonderry. The specimen described measured eighteen inches in length ; the top of the head flat and rather broad ; the begin- ning of the back elevated and rather rounded ; the eye large, lateral, elongated horizontally ; temporal orifices rather small, and placed immediately behind the posterior angle : first dorsal fin considerably larger than the second ; both of the same SMOOTH HOUND. 395 shape, with an elongated free point at the base projecting backward, the centre of the first dorsal at the distance of six inches, and that of the second at twelve inches, from the point of the nose. Under surface of the head flat ; nostrils semilunar in shape, with a central free cutaneous valve ; the mouth half the width of the whole under surface, rather an- gular in shape than semicircular ; upper lip on each outside ending in a free elongation of the membrane; the teeth small, flat, like those of a young Skate ; pectoral fins large, com- mencing at three inches and a half from the point of the nose : ventral fins under the space between the two dorsals ; the anal fin begins in a line under the middle of the second dorsal fin, but being only half its size, ends but a little behind it : the upper part of the caudal fin is a long narrow horizon- tal slip ; the free part of the under portion is made up of two triangular portions, the first of which is long, the second and last short. The surface of the body smoother than that of Sharks in general : the colour of the upper part of the head, body, and fins, pearl grey ; under parts greyish yellow white : lateral line prominent ; above it the body along its whole length is marked with numerous small circular white spots, which, as before stated, are most conspicuous while this fish is young. 396 SQUALID.E.

THE BASKING SHARK, so called from its habit of remain- ing occasionally at the surface of the water almost motionless, as if enjoying the influence of the sun's rays, whence it is also on some parts of the Irish and Welsh coasts called Sun- fish, is one of the largest of the true fishes, and has been known to measure thirty-six feet in length. It has been seen generally from the month of June to the commencement of winter. When northerly winds prevail, it is most frequent on the west coast of Scotland. It has also been seen on the BASKING SHARK. 397 north and on the west coasts of Ireland. If westerly winds prevail, it is not unusual to see them along the whole line of the southern coast. It has been taken on the coasts of Waterford, Wales, Cornwall, Devonshire, Dorsetshire, and several times at different places on the coast of Sussex. The specimen described and figured by Sir E. Home, in the Philosophical Transactions for 1809, was taken off Hastings ; and the largest specimen I have seen, which measured thirty- six feet in length, was caught some years since off Brighton. From our southern coast it frequently wanders as far to the eastward and south as the coast of France ; and the fish de- scribed and figured by M. de Blainville in the eighteenth volume of the Annales du Museum, I have very little doubt was of the same species as that described by Sir E. Home, which has been already referre,d to. The difficulty of obtaining a perfect view of this unwieldy fish, either when floating in water, or when from its great weight it lies partly imbedded in the soft soil of the sea- shore, has led to the differences which appear in the repre- sentations of it which have been published by different na- turalists. The Basking Shark is said to exhibit but little of the ferocious character of the Sharks in general, and is so indif- ferent to the approach of a boat as to suffer it even to touch its body when listlessly sunning itself at the surface. From its habit of swimming slowly along with its dorsal fin, and sometimes part of its back, out of water, it has obtained in the North the name of Sail-fish. In Orkney it is called Hoe-mother, and by contraction Homer, — that is, the mo- ther of the Picked Dog-fish, which is there called the Hoe. If deeply struck with a harpoon, the Basking Shark plunges suddenly down, and swims away with such rapidity and vio- lence as to become a difficult as well as a dangerous capture. 398 SQUALID.E. This species has the smallest teeth in proportion to its size of any of the Sharks. No remains of fish have been found in its stomach. One examined by Mr. Low contained a red pulpy mass, like bruised crabs, or the roe of Echini. Mr. Low adds, that this Shark's appearance, manners, and wea- pons do not indicate, it to be a ravenous fish. Linnseus says that its food is Medusa, and Pennant considered that it sub- sisted on marine plants. The body is thickest about the middle, and diminishes towards both extremities ; when afloat the form is nearly cy- lindrical ; the skin thick and rough, of a brownish black co- lour, with tints of blue. The head conical, the muzzle short, rather blunt, smooth, and pierced with numerous circular pores ; eyes near the snout, small, oval, the elongation hori- zontal, the irides brown ; half-way between the eye and the first branchial opening is the temporal orifice, oblique and small ; branchial openings five on each side, of great vertical length, each set including the whole side of the neck, and leaving only a small space above and below ; nostrils oval, small, placed rather laterally, and opening on the edge of the upper lip ; pectoral fins of moderate size for so large a fish, — perhaps, as before stated, the largest of the true fishes, — the form somewhat triangular, placed close to the last bran- chial orifice, convex anteriorly and thick, slightly concave and much thinner behind ; the ventral fins also of moderate size, rather elongated at the base, placed behind the middle of the whole length of the fish, convex in front, concave be- hind, the inner and posterior half free, exhibiting in the figure chosen the cylindrical appendages peculiar to the male. The first dorsal fin, placed before the middle of the whole length of the fish, is much the larger of the two, forming an elevated triangle ; anterior edge but slightly convex, posterior edge concave, with an elongated point at the base directed BASKING SHARK. 399 backwards : the second dorsal fin much smaller than the first, rounded above, attached throughout half its base only, and placed at two-thirds of the distance from the first dorsal to the caudal fin ; the anal fin is still smaller than the second dorsal, but of the same shape. From the line of the anal fin to the base of the tail there is a strong and prominent keel-like edge on each side ; and just in advance of the base of the caudal fin, both above and below, is a groove, — that underneath rather smaller than that above. The caudal fin divided into two lobes, the upper one larger than the lower ; the posterior edge of the caudal fin appears to become notch- ed and abraded by age and use, and is frequently found un- equal at its margin, and variable in shape. The vignette below represents the Argulus foliaceus of Jurine ; another species of parasitic animal occasionally found attached to fresh-water fishes. I have specimens that were taken from the Pike and the Trout. The figure on the left- hand represents the upper surface of a male : by the powers of the microscope some of the vessels of the body are ren- dered visible through the external tunic. The figure on the right-hand represents the under surface of a female : the ova are very conspicuous. The small figure between the two is of the natural size. 400 SQUALID.E. CHONDltOPTERYGII.

THE PICKED DoG-Fisn is a very common species, at once distinguished from the other British Sharks by the sin- gle spine placed in advance of each of its two dorsal fins, — a weapon from which it derives its specific appellation, pick being synonymous with pike or spike. Among the Scotch islands, where it is called the Hoe, it appears most numer- ous at the full and change of the moon, on account of the then greater quantity of water, and consequent increased strength or race of the tide in some of the narrow straits. PICKED DOG-FISH. 401 Being gregarious, they frequently make their appearance in such shoals that the fishermen load their boats to the water's edge with them ; and, according to Mr. Low, they prove a valuable capture. The flesh is dried and eaten : the livers yield a large quantity of oil, while their intestines and other refuse parts are strewed over the land as manure. Dr. Neill says this species is very common in the Forth during the Herring season, where numbers are caught ; but their flesh is not eaten in that neighbourhood. The Picked Dog-fish is found in numbers at most of the fishing stations along the east coast, round to Kent and Sus- sex on the south coast, where it is almost universally called the Bone Dog. According to Montagu's MS. it is very numerous in Devonshire and in Cornwall : Mr. Couch says, " It is the most abundant of the Sharks, and is sometimes found in incalculable numbers, to the no small annoyance of the fishermen, whose hooks they cut from the lines in rapid succession. I have heard of twenty thousand taken in a scan at one time ; and such is the strength of instinct, that little creatures not exceeding six inches in length may be found, in company with the larger and stronger, following schulls of fish, on which at that time it is impossible they should be able to prey. The Picked Dog bends itself into the form of a bow for the purpose of using its spines, and by a sudden motion causes them to spring asunder in opposite directions; and so accurately is this intention effected, that if a finger be placed on its head, it will strike it without piercing its own skin. This fish is subject, like many others, to occasional monstrosity. A friend of mine was in possession of a Pick- ed Dog-fish with two heads, the separation continuing so far back as behind the pectoral fins. The fisherman wjio found it informed me that there was only one egg attached to it, and that it must have been dropped from the mother after 402 SQUALID^E. she was taken. The young are produced at various periods from June to November." The whole length of the specimen described was eighteen inches ; the top of the head flat ; the temporal orifices large, and seen from above : first dorsal fin commencing at one- third of the whole length ; rather small in size ; front edge convex, concave behind; the point of the spine preceding the fin half as high as the fin : the second dorsal fin half-way be- tween the first and the end of the tail ; small in size, with a spine as high as the fin : the nose rather pointed ; the eyes lateral, elongated horizontally ; temporal orifices behind, large, but above the line of the eye ; nostrils small, with a minute valve ; mouth semicircular, when quite open nearly round ; the teeth from the centre of both jaws with points projecting outward on each side, the edges sharp ; pectoral fins large, commencing half-way between the snout and the first dorsal ; anal fins small, placed intermediate, in a vertical line, be- tween the first and second dorsal ; no anal fin ; tail powerful, upper membrane broad, the lower anterior part triangular, ending in a slip prolonged backward. The upper part of the head, body, and fins, slate grey ; under parts yellowish white ; young specimens generally exhibit a few white spots. Skin moderately rough on passing the finger upwards towards the head ; in the contrary direction quite smooth. GREENLAND SHARK. 403 CHONDROPTERYGII. SQUALID&. THE GREENLAND SHARK.

THIS species of Shark, which is a native of the Northern Seas, has been twice noticed in Scotland, and is therefore entitled to a place in this work. According to Dr. Fleming, one was caught in the Pentland Firth in 1803 ; and another, measuring thirteen feet and a half long, found dead at Burra Firth, Unst, was seen by Mr. Edmonston. This Shark appears to be well known to several Northern zoologists ; and the following account, as well as the figure, of this fish, is derived from the valuable work on the Arctic Regions by Captain W. Scoresby. 404 SQUALID^E. " The Squalus borealis is twelve or fourteen feet in length, sometimes more, and six or eight feet in circumfer- ence. The opening of the mouth, which extends nearly across the lower part of the head, is from twenty-one to twen- ty-four inches in width. The teeth are serrated in one jaw, and lancet-shaped and denticulated in the other. It is with- out the anal fin, but has the temporal opening ; the spiracles on the neck are five in number on each side. The colour is cinereous grey. The irides are blue, the pupil emerald green." " This Shark is one of the foes of the Whale. It bites it and annoys it while living, and feeds on it when dead. It scoops hemispherical pieces out of its body, nearly as big as a person's head ; and continues scooping and gorging lump after lump, until the whole cavity of its belly is filled. It is so insensible of pain, that though it has been run through the body with a knife and escaped, yet, after a while, I have seen it return to banquet again on the Whale, at the very spot where it received its wounds. The heart is very small : it performs six or eight pulsations in a minute, and conti- nues its beating for some hours after taken out of the body. The body, also, though separated into any number of parts, gives evidence of life for a similar length of time. It is therefore extremely difficult to kill. It is actually unsafe to trust the hand in its mouth, though the head be separated from the body. Though the Whale-fishers frequently slip into the water where Sharks abound, there has been no in- stance, that I have heard of, of their ever having been at- tacked by the Shark." " Besides dead Whales, the Sharks feed on small fishes and crabs. A fish, in size and form resembling a Whiting, was found in the stomach of one that I killed ; but the pro- cess of digestion had gone so far, that its species could not GREENLAND SHARK. 405 be satisfactorily discovered. In swimming, the tail only is used : the rest of its fins being spread out to balance it, are never observed in motion but when some change of direction is required." " To the posterior edge of the pupil of the eye is attached a white vermiform substance, one or two inches in length. Each extremity of it consists of two filaments, but the cen- tral part is single. The sailors imagine this Shark is blind, because it pays not the least attention to the presence of a man ; and is, indeed, so apparently stupid, that it never draws back when a blow is aimed at it with a knife or lance." The eyes of this Greenland Shark, with the appendages, were brought home by Captain W. Scoresby, preserved in spirits, and submitted to Sir David Brewster, who gave one specimen to Dr. Grant. The appendage proved to be a new species of parasitic animal, which Dr. Grant named Lernaa elongata, and described it, adding a figure of it, in the se- venth volume of the Edinburgh Journal of Science. The imperfection of the vision of the fish was probably produced by the various perforations made in the cornea by the tenta- cula of this new species of Lernaa ; as it is by those organs that these parasitic animals retain their hold and live upon the fluids extracted from the animal to which they adhere. This species of Lernaa is perhaps the largest known : it mea- sured three inches in length. The genus of Sharks next in order, according to Cuvier's arrangement in the Regne Animal, is that of Zygana, or Hammer-headed Sharks, of which a single specimen is re- corded by Messrs. C. and J. Paget, in their Sketch of the Natural History of Yarmouth, page 17, to have been taken there in October 1829, the head of which is now preserved in the Norwich Museum. The specific name of the example taken, and here referred 406 SQUALID.E. to, has not, I believe, been determined. A reference to a paper by M. Valenciennes in the ninth volume of the Me- moir es du Museum, which supplies detailed descriptions of four species of this genus, would probably settle this point. A representation of the most common species, Zygtena malleus, Val. is here given as a vignette to draw the atten- tion of observers to the subject. ANGEL-FISH. 40*7 CHONDROPTERYGIL SQUALIDJE.

THIS fish, certainly more remarkable for the singularity of its form than for its beauty, is called Angel-fish in England, France, and Italy, and is said to have acquired that name from the extended pectoral fins having the appearance of wings : it is also called Monk-fish, because its rounded head looks as if enveloped in a monk's hood. Mr. Donovan says the form of its body has obtained for it in some places the 408 SQUALID*:. name of Fiddle-fish ; and it is also called Shark-Ray, from its partaking of the characters of both Shark and Ray, though in some respects distinct from either. It is, however, by no means so truly osculant between those families as the exotic genus Rhinobatus. It is most numerous on the southern coast of our island ; but is occasionally taken in the Forth, and some other parts of the east coast, particularly about Cromer and Yarmouth. It is common on the coasts of Kent and Sussex, where it is called a Kingston, — a name for it that occurs in Merrett's Pinax. It is also taken in Cornwall ; and is recorded as oc- curring in Ireland on the coasts of Kerry, Waterford, Dub- lin, and Belfast. This fish is very voracious, and feeds on the smaller flat- fishes, which, like itself, swim close to the bottom ; occasion- ally, like them also, hiding itself in the loose, soft soil that floats over it. The Angel-fish sometimes attains a large size. Cuvier, Pennant, and others, mention having seen specimens that would have weighed one hundred pounds. The flesh is now considered indifferent and seldom eaten, but is said to have been formerly held in high estimation. The skin is rather rough, and is used for polishing, and other works in the arts : Mr. Donovan also says that the Turks at the present time make shagreen of it. A second species of this genus has been supposed to occur on our coast ; but the Angel-fish^ is probably liable to some variation in colour, depending on the nature of the ground in the locality in which it is found : the sexes also exhibit some differences. The females produce their young alive in June. This species is said to attain the length of seven or eight feet ; the specimen described measured but fourteen inches ; the breadth of the head in the line of the temporal orifices ANGEL-FISH. 409 three inches, whole breadth across the pectoral fins from angle to angle seven inches and a half, breadth across the ventral fins four inches and one quarter ; head depressed, rounded at the anterior margin ; eyes on the upper surface, distance between them one inch and one quarter ; temporal orifices very large, one inch and a half apart, elongated transversely, about as far behind the eyes as these are from the anterior margin of the head ; pectoral fins large, lateral, pointed in front, triangular on the outer edge, and rounded posteriorly; sides of the body of the fish parallel behind their free edges ; ventral fins elongated, slightly rounded, con- tracted in breadth behind ; commencement of first dorsal fin even with the posterior edge of the ventrals ; the second dor- sal fin begins at the half of the distance between the com- mencement of the first dorsal and the caudal fin ; tail with an equal-sized triangular lobe above and below. The mouth is very wide, opening on the anterior margin of the head ; the angles of the mouth under the external angles of each tem- poral orifice ; teeth long and pointed ; branchial apertures elongated ; the parallelism of the sides of the fish most con- spicuous from below ; anal orifice rather before the middle of the whole length ; the colour of all the under parts dirty white ; the surface smooth ; all the upper surface granulated, rough, of a dark mottled chocolate brown ; a row of short spines, directed backwards, are ranged along the central line of the back between the ventral fins.

THE earliest notices of this fish on our coasts by English writers were made by Smith in his History of Waterford, and afterwards by Pennant and Walsh ; but as, according to * The family of the Rays or Skate. ELECTRIC RAY. 411 Baron Cuvier, several species have been included under the name of the Raia Torpedo of Linnseus, the true name of the British species is still doubtful, and it remains therefore for some naturalist who is fortunate enough to obtain a British specimen to determine the particular species of our coast. Colonel Montagu, in his MS. notes, mentions having met with two examples of the Torpedo ; but no description of either of them is given. The first was of small size, and was taken at Torcross, where it was so rare as to be unknown to the oldest of the fishermen of that place. Of the second, the notice is as follows : — " I observed a very large speci- men that was taken on a Turbot-hook off the coast of Ten- by, in Wales. It was dead when disengaged from the hook, or the fisherman would certainly have had a shock that would have made him remember the species again. It appeared, however, so rare an occurrence here, that no one knew the fish, which was exhibited as an extraordinary creature. Its weight was about one hundred pounds." The figure at the head of this subject was taken from a small specimen which appears to be of the same species as that figured by Pennant in the British Zoology ; but Pen- nant's plate, which exhibits in the two outside figures the under and upper surface of a female, the third and middle figure being that of a male of smaller size, appears to have been copied from a larger print representing specimens taken on the sea-shore in the neighbourhood of La Rochelle. Mr. Donovan's figure differs from that of Pennant in exhibiting a marbled appearance on its upper surface, with five distinct dark spots : it differs also in its form and proportions. The electrical powers of the Torpedo are so well under- stood by the different names that have been applied to it, as well as by the various and voluminous accounts that have been published, that it is unnecessary to repeat here what RAIJDJE. has already appeared so often in print elsewhere. The situa- tion of the apparatus or structure from which these species derive their extraordinary power is indicated by the two ele- vations, one of which is placed on each outside of the eyes and temporal orifices, and extending to the lateral external rounded edges. The apparatus occupies the whole of the space between the upper and under surface of the body, and is composed, as shown by the figures of Walsh and Pennant, of a great number of tubes arranged perpendicular to the plane of the upper and under surfaces, which when exposed by a transverse section have very much the appearance of a portion of honeycomb. The tubes contain a mucous secre- tion, and the structure is largely provided with nerves deriv- ed from the eighth pair. It is said that when the shock is given, the convex part of the upper surface is gradually de- pressed, the sensation is then felt, and the convexity sud- denly returns. The whole use of the electrical apparatus and power to the fish can only be conjectured. That it serves as a means of defence, is very probable ; that it also enables a slow, inact- ive fish to arrest and obtain as food some of the more active inhabitants of the deep, is also probable. Mr. Couch thinks other powers may be derived from it, and his opinion is thus expressed : — " One well-known effect of the electric shock is to deprive animals killed by it of their organic irritability,* and consequently to render them more readily disposed to pass into a state of decomposition, in which condition the di- gestive powers more speedily and effectually act upon them. If any creature more than others might seem to require such a preparation of its food, it is the Cramp- Ray, the whole canal of whose intestine is not more than half as long as the stomach ." * The bodies of animals killed by lightning do not become stiff. ELECTRIC RAY. 413 " So long ago as the time of Dioscorides, the physician of Anthony and Cleopatra, the shock of this fish was recom- mended for medical purposes, and especially for pains of the head ; and this may be considered as the earliest record of the application of electricity to medicine. In later times, it was applied to the cure of gout ; the patient being directed to keep his foot on the fish until the numbness extended to the knees. Baron Humboldt remarks, that the will of the fish directs the effect to whatever part it feels most strongly irri- tated, but only under the influence of the brain and heart. When a fish was cut through the middle, the fore part of the body alone gave shocks." But little of its habits are known : it is said to prefer soft and muddy ground, where its actions are slow and inert. It is rare on the British coast ; but two or three species inhabit the Mediterranean, and others have been found in various parts of the world. Not being certain of the British species, no description is ventured upon. The observer on our coast who obtains a specimen will find specific characters in the Regne Animal, and in the Faune Fran^aise. The vignette below represents a view of Erith Church. RAIIDJE.

Generic Characters. — Form of the body rhomboidal, very much depressed ; tail long and slender, generally armed on the upper surface with one or more rows of sharp spines ; two small fins near the end of the tail, and sometimes a small terminal or caudal fin ; the eyes and temporal orifices on the upper sur- face of the head ; nostrils, mouth, and branchial apertures, beneath ; teeth flattened, lozenge-shaped, the inner angle elongated in old males. THE RAYS, or Skate, as they are popularly called, are remarkable for tlie rhomboidal form and consequent breadth LONG-NOSED SKATE. 415 of their bodies, contrasted with their long narrow tails, fre- quently furnished with two and sometimes three small fins, and mostly armed with one or more rows of sharp spines along the whole length. The whole body is very much de- pressed ; the great breadth of it is produced by the expansion of what are considered as the pectoral fins, the base of each of which is equal to the whole length of the side of the fish. The Skate may almost be considered as having no true head or neck, the sides of both being included and thus protected by the expanded anterior margin of each pectoral fin. The nostrils, mouth, branchial and anal apertures, are on the under surface ; the eyes and temporal orifices on the upper surface. The texture of the skin of the body varies consi- derably, and will be referred to when describing the different species. From the peculiar form of the body, admirably adapted to exist at the bottom of the water, the Skate may with more propriety be called a Flatfish than any species of the Pleuronectidte. Their mode of progression is not very easily described : it is, when they are not alarmed, per- formed with a slight motion of the pectoral fins, something between a slide and a swim. I once heard a North- country fisherman call it sluddering. When a Skate makes the best of its way either to gain a prize in the matter of food, or to escape an enemy, great muscular exertion is evident. The mode of defending itself, as described by Mr. Couch, is very effectual : the point of the nose and the base of the tail are bent upwards toward each other ; the upper surface of the body being then concave, the tail is lashed about in all di- rections over it, and the rows of sharp spines frequently inflict severe wounds. Some sexual peculiarities require particular notice. The woodcut introduced overleaf represents in the left-hand portion an inside view of one-half of the mouth of an adult male; 416 RAIID.E. that on the right, an inside view of one-half of the mouth of an equally adult female of the Thornback Ray. While both are young, the teeth in both sexes are alike broad and flat ; but as the male acquires age and sexual power, the teeth that are nearest the centre begin to alter in form and become pointed, as will be seen on close examination, by an elonga- tion of the internal angle ; all the points being directed back- wards or towards the throat. Some exceptions to this appa- rent rule will be pointed out. Another sexual peculiarity in which the Skate resemble the Sharks is the cylindrical appendage to each ventral fin in the males. The figure at the head of this subject is taken from the under surface of a female, in which no appendages exist : the second figure of the true Skate, the next in suc- cession, is from the under surface of a young male, and small appendages lying on each side close to the tail may be seen ; and even in very young specimens, not more than three inches in breadth, the sexes may be determined by the constant existence of these appendages in the males. The figure of the third species is taken from the upper surface of an adult male, and exhibits these appendages of much greater length : their use may be inferred from the name they bear — they are usually called claspers. This third figure of the Sharp-nosed Ray exhibits also other peculiarities com- mon to males : these are the clusters of spines outside the LONG-NOSED SKATE. 417 eye and temporal orifice on each side, and the regular rows of spines towards the upper outer surface of the pectoral fins. The elongation of the central teeth, the development of the cylindrical appendages, and the appearance and growth of the clusters and rows of spines on the upper surface at the parts pointed out, may be considered analogous to those sexual distinctions which exist in many species of birds and mam- mals, and which have been called by John Hunter and others, secondary sexual characters. These spines on the upper surface of the males occur in the different species of Skate with smooth skins, as well as in the others, and are entirely independent of those spinous productions of the cuticle which distinguish two British species, and will be more particularly noticed hereafter. It may here be stated generally, that the Skate are very voracious : their food con- sists of any sort of fish that they can catch, with mollusca, testaceous or naked, and Crustacea. So powerful are their muscles and jaws, that they are able to crush the strong shell of a crab with ease. As in the Sharks, the females are larger than the males. The under surface of the Skate at the head of this subject presents two central circular cavities. The upper one just below the transverse mouth is bounded laterally by the five branchial apertures on each outside ; within this cavity the gills are placed. The circular cavity below is the abdomen, and contains the stomach, intestines, and other viscera. The heart is placed immediately in the centre between the two cavities, and is protected by a broad and strong transverse cartilaginous arch, the situation of which is indicated. The young are produced towards the latter part of spring, or during summer. They are deposited by the parent fish in thin horny cases, like those of some of the Sharks already described ; but they are more square in form, as 418 the representation here inserted will evince. These horny cases of the Rays, like those of the Sharks, are also called purses; and on the coast of Cumberland bear the name of Skate-barrows, from the resemblance in shape to a four-handed machine by which two men carry goods. As 'the young Skate increases in size, the angular parts of the body curve over for a time, till the fish ultimately escapes to provide for itself in a much wider but more dangerous region. The eight species of true Rays which are found on the coasts of this country will be arranged here in two divisions ; the first of which contains four species, having the snout more or less elongated and sharp : the second division contains also four species with blunt noses, the two last of which are furnished with numerous sharp spines on various parts of the surface of the body, and thus lead to the more powerfully armed short-nosed species which will follow. The Skate, as food, are held in very different degrees of LONG-NOSED SKATE. 419 estimation in different places. In London, particularly, large quantities are consumed, and the flesh is considered delicate and well-flavoured ; but on some parts of the coast, though caught in considerable numbers, both by lines and nets, the flesh is seldom devoted to any purpose beyond that of baiting pots for catching crabs and lobsters. Skate are in the best condition for the table during au- tumn and winter. In spring, and in the early part of sum- mer, they are usually maturing eggs or young, and their flesh is then soft and woolly. The Long-nosed Skate is immediately distinguished from any other Skate found on the British coast, not only by the great length of the nose, but also by the distance between its most extreme point and the transverse line of the mouth ; cha- racters particularly observable in comparison with the species next in order, with which it most assimilates in colour. The snout is very much produced, narrow and sharp, slen- der as far as the eyes, from whence the body dilates gradually to its greatest breadth, which is behind the centre ; the whole length of the body and tail one-third longer than the width. On the upper surface the body is slightly roughened, and of a light lead colour ; the tail rather more rough, with a row of large crooked spines on each side of the central line, and this species is observed never to have more or less than these two lateral rows ; the small fins on the tail not far remov- ed from each other, the second about its own length from the end. The under surface is a dirty greyish white, marked with dusky specks like the true Skate next to be described ; but the body is thinner in substance than either that or the Sharp-nosed Skate : the nostrils are lobed ; the mouth nar- row ; the teeth in old males sharp, with frequently nine or ten spines above the eyes ; on the snout two rows of minute tubercular spines ; behind the head seven or eight spines 420 RAIIDJ5. ranged in a line along the dorsal ridge ; towards the outer upper edge of the pectoral fins on each side are the usual rows of sharp hooked spines, and close to the tail the long pendent claspers. Montagu having figured in the Werne- rian Memoirs, as referred to, the upper surface of a male, the figure here given represents the under surface of a fe- male. By some of the West-country fishermen this species is called the Dun Cow : it attains considerable size, and is said to feed on Sand-eels and Sand-launce. According to Mr. Couch, it frequents deep water, and is not caught through the winter : fishermen state that it is exceedingly violent when hooked. I may here state generally, that the greater part of the Skate brought to market are taken in the trawl- nets. SKATE. CHONDROPTERYGII. 4*1 RA1IDJE. THE SKATE. BLUE SKATE, and GREY SKATE, Scotland.

THIS species, which is frequently called the True Skate, to distinguish it from the Thornback and Homelyn, which are also popularly called Skate, is not so commonly taken as either, but is still better than either as an article of food. It appears to be found among the Orkneys, and on the coast of Scotland, where it is called Blue Skate and Grey Skate. From thence southward as far as Kent, and again westward to Cornwall, it is found along the whole line of coast. In Ireland, the Skate is taken from Cork up the east coast to Antrim, and from thence northward and westward to Londonderry and Donegal. At Lyme Regis, on account of its dusky grey colour, it is called the Tinker. In this species both sexes when adult have sharp teeth, the points beginning to elongate by the time the body of the fish has attained the breadth of twelve or fourteen inches. The females are generally called Maids ; and fishermen dis- tinguish the females of the three species of most frequent occurrence by the names of Skate Maid, Thornback Maid, and Homelyn Maid, — frequently calling the old male of the Skate with his two long appendages the Three-tailed Skate. In each of these species the females are observed to be much more numerous as well as larger than the males. Pennant mentions having seen a Skate that weighed two hundred pounds : it is very voracious, and Mr. Couch has known five different species of fish, besides Crustacea, taken from the stomach of a single individual. There is reason to believe that the true Skate produces its young later in the season than either the Thornback or the Homelyn, The breadth of the body is to its length nearly as four to three ; the form of the nose conical : the lines from the ex- treme lateral angle of each pectoral fin being nearly straight, similar lines taken in a direction backward to a point on the tail two inches below the end of the ventral fins, would form a true rhomb : the eyes are slightly elevated above the line of the upper surface of the body, with a short, hard tubercle in the front of each, and a second on the inner side of each ; the hides yellow ; the temporal orifices valvular, and placed SKATE. 423 close behind : the dorsal ridge of the body without spines till near the origin of the ventral fins ; then commence a single row on the centre, reaching along the tail as far as the first of the two small fins, all the points of the spines directed back- wards ; one spine between the two small dorsal fins. On the sides of the tail of a female of small size there were no lateral spines ; but in a young male of the same size, there were several lateral spines on each side, the points of which were directed forwards, and are in that respect characteristic of this species. The colour of the upper surface of the body and tail greyish brown : the margins anterior to the angles of the pectoral fins tinged with reddish brown ; those behind the angles brownish black, darker than the body : the colour on the under surface is sooty white, with dark lines in vari- ous directions, and numerous blue specks with small sharp points disposed among them over the surface. The nostrils are valvular, half the width of the mouth in advance of each of its angles ; the mouth rather wide ; the teeth in this spe- cies are sharp in both sexes when adult, the inner angles of the central teeth beginning to elongate in specimens when they are about twelve inches in breadth across the body. I may here add that the true Skate, the subject of the pre- sent article, the Long-nosed Skate which precedes it, and the Sharp-nosed Skate which is next to be described, are, in some localities, included under the general term of Skate, from their similarity in colour. 424 CHONDROPTERYGll.

THIS species, says Mr. Couch, from whose drawing the figure is taken, " may be easily recognised by its sharp snout, by the waved line of the margin of the body from the snout to the extremity of the expansion, and by its pure white colour on the lower surface. It is the largest of the British Rays ; for though in length and breadth it may not exceed the common Skate, its superior thickness renders it heavier." SHARP-NOSED RAY. 425 Colonel Montagu, in the Wernerian Memoirs already quoted, says, by way of further distinction, the snout in this species is slender, the lateral margins in a moderately-sized fish running nearly parallel to each other for three or four inches at the extremity. The skin is smooth, with the ex- ception of the spines on the upper surface, peculiar to the males, as shown in the figure ; the colour a plain brown with- out spots or lines, and never so dark as the Skate last de- scribed, with which it is sometimes confounded. The teeth of the males, according to a specimen of the mouth very kindly sent to me by Mr. Couch, are longer, more pointed, and sharper than those of any other species I have had an opportunity of examining. The tail is armed with three rows of spines. Mr. Couch states that the smaller-sized specimens are taken throughout the year ; but those which are larger keep in deep water, and are only taken in summer and autumn. The French are great consumers of Skate, and this species is their favourite fish : their boats come to Plymouth during Lent to purchase Skate, which they preserve fresh and mqist during the run back to their own coast by keeping them covered with wet sand. This species is the White Skate of the Orkneys, and of Scotland generally ; and is said to have been taken on the south-east coast of Ireland. It is doubtful whether this species be the oxyrhynchus of the older authors : it is certainly not the oxyrhynchus of Bloch, part iii. plate 80, which is the R. chardon of other authors ; a species with a short nose, and further remarkable for the intense black colour of its upper surface, and which there is reason to believe has been taken once in Cornwall ; but the specimen had been too much mutilated before Mr Couch saw it to enable him to determine correctly.

THE BORDERED RAY, as it is called from the broad dark marginal edge of its pectoral fins, has been taken at Liverpool, Brighton, and Weymouth ; it has also been taken at Dieppe, and noticed by M. Noel and Lacepede. It is a well-known species in the Mediterranean, described by M. de Blainville, by the Prince of Musignano, and M. Risso. But little is known of its habits, and it does not attain a large size. M. Risso states that the flesh is con- sidered pretty good. I avail myself, by permission, of Mr. Jenyns1 description BORDERED RAY. 427 of this species, taken from a specimen obtained at Wey- mouth by Professor Henslow. " Total length fifteen inches six lines : length of the head from the end of the snout to the spiracles behind the eyes, three inches six lines ; of the tail from the vent to its extremity, seven inches nine lines : greatest breadth across the pectorals, eleven inches three lines. The total length of M. de Blainville's specimen was two feet. The form rhomboidal ; the transverse diameter rather more than one- third greater than the length from the end of the snout to the vent : snout elongated, projecting considerably from between the pectorals, terminating in a sharp point, with the lateral margins nearly parallel for the last quarter of their length : mouth moderately wide ; jaws transverse ; teeth numerous, closely set, in several rows, roundish or somewhat quadrilateral at the base, each terminating in a sharp point : nostrils in a line with the corners of the mouth, and rather more than half-way between them and the upper margins of the pectorals ; a channel from the nostrils to the mouth, covered by a membranous flap : eyes and spiracles both large : skin perfectly smooth above ; and beneath also, excepting along the anterior margins of the pectorals and the surface of the snout, which are set with very minute spines and denticles : one large spine above each eye, in- clining backwards, and another smaller one behind each eye : no spines on any part of the back, but three rows on the tail, one occupying the middle ridge, the two others the sides ; the spines on these rows strong and sharp, and mostly inclining backwards : tail scarcely longer than the body, depressed, rather stout, with two moderately-sized finlets of equal form, nearly contiguous ; scarcely the rudiment of a caudal : pectorals broad, with the anterior margins hol- lowed out, and not prolonged beyond the basal half of the 428 RAIID.E. snout ; ventrals moderate, deeply notched or bilobated. Ge- neral colour of the upper part reddish brown, somewhat paler on the pectorals, with a faint indication of round whit- ish spots; beneath white, with a broad border all round, especially beneath the angles of the pectorals, of dark red- dish brown, approaching to dusky : tail entirely black."

THIS smooth-skinned spotted Ray, called Raia lavis and Homelyn so long ago as the time of Merrett,* and one of our most common species along the line of our southern coast, has not been so well distinguished or so clearly defined by some authors as its obvious characters admit and require. The males, though they have, like the females, a perfectly * Pinax Rerum Naturalium Britannicarum. London, 1667, p. 185. 430 smooth skin, have also spines about the eyes, rows of small hooks on the upper surface of the pectoral fins, one row of spines along the dorsal ridge, with one on each side a little below the commencement of the dorsal series, and when full- grown, with three rows of strong spines on the tail. Thus extensively armed, the male has been called rubus: but those authors who quote as a synonyme the R. rubus of Bloch, part iii. pi. 84, have been misled by the German ichthyolo- gist, whose figure proves his fish to have been a male of the Thornback, of which his plate 83 is the female. The Homelyn of our coast has been best made out and described by Mr. Donovan, Colonel Montagu, and more recently by the Rev. Mr. Jenyns, under the different names here quoted. This species is liable to some occasional variation in the manner in which the upper surface of the body is spotted ; the spots are sometimes numerous, at others sparingly distri- buted : I have seen it quite free from spots, and have also seen it with only one eye-like spot on each side, not far re- moved from the line of the back. I have mentioned that the skin, independent of the accessory organs, is quite smooth. These variations have given rise to the different trivial names miraletus, oculata, lavis, and maculata, which have been applied to it by different authors, from the appear- ance of the particular specimens examined. Colonel Montagu, referring to the miraletus and rubus of Mr. Donovan, had no doubt that they were both identical with his own maculata, since, being a common species on the Devonshire coast, he had ample opportunities of seeing it under its different appearances. Mr. Donovan has given correct figures both of the Mirror Ray and of the Homelyn, as quoted, the latter under the trivial term rubus ; but he believed with Montagu, that they HOMELYN RAY. 431 were not distinct species. Mr, Donovan had noticed two similar eye-like spots on several small examples of the true Skate (batis) ; and I possess young specimens of the Thorn- back (clavata) with the same sort of ocellated lateral spots, and have seen many others of the three most common spe- cies. Mr. Donovan's remark accords so closely with my own view, that I insert it here in his own words : — " Although we present this as the Raia miraletus of Linnseus with perfect confidence, it is not without some hesitation at least that we can offer it as a distinct species. In every respect, except the ocellar spot on the wings, it per- fectly agrees with the Homerling Ray, and may possibly prove, on further examination of other specimens, to be only a iusus, or remarkable variety of that fish." The figure given at the head of this subject exhibits the eye-like lateral spots, from the possession of which it has been called miraletus and oculata : the smoothness of the surface of the skin, and its numerous smaller spots, suffi- ciently warrant the terms Itevis and maculata. The words oculata and lavis were combined by some of the older au- thors, and probably referred to this species. The Homelyn and the Thornback, which are not very dis- similar in shape, though otherwise perfectly distinct, are the two species most common in the London market : a large proportion of both are taken in the trawl-nets. The form is rhomboidal ; the diameter of the body about one-fourth greater than the length : the nose short and blunt, its projection beyond the outline of the pectorals but small : in a young male specimen of twelve inches in breadth the se- condary sexual characters begin to appear ; there are numer- ous small spines about the nose, and some extending along part of the anterior edge of the pectoral fins ; two or three prominent spines before and behind each eye, with rough 432 HAIID.E. granulations on the surface of the skin before and between them : the more conspicuous characters that distinguish the males have been already noticed. The eyes and temporal orifices are large : the central row of dorsal spines commence above the middle of the body, with one strong spine on each side of it about the middle of the body and in the line of its greatest diameter : the series of spines on the dorsal ridge extend along the centre of the tail, with a row along each side of it in adult specimens ; in young examples the series on each side is not complete. On the tail are two small fins, with two spines between ; the points of all the spines on the central line and on the tail directed backwards. The colour of the upper surface is a pale yellowish or reddish brown, with spots of darker brown, subject to the variations that have been already pointed out ; the colour of the under surface plain white ; the skin smooth ; nostrils and mouth near the end of the nose ; the mouth transverse, rather small. Montagu says, both sexes of the maculata have sharp teeth ; but this refers to examples that are perfectly adult : young males of small size, and females when larger, have the teeth blunt ; in old males, and very probably also in old fe- males, from the operation of those laws which influence the secondary sexual characters, the teeth become pointed. The term Sand Ray is in some localities exclusively ap- plied to the males of this species, from their greater rough- ness. SMALL-EYED RAY. CHONDROPTERYG11. 433 RA11D&.

Vert. p. 515, sp. 204. ,, ,, Painted Ray, COUCH'S MS. COLONEL MONTAGU and Mr. Couch appear to be the only British naturalists who have obtained this species ; and it must be considered a rare one, since the first of these gentlemen saw but two examples, and the latter has only seen one. The very small size of the eye is stated by both to be a remarkable and striking distinction. The length of the specimen obtained by Mr. Couch was thirty-three inches and a half, of which the tail measured 434 RAIID.E. thirteen inches ; breadth across the fins twenty-four inches ; the eyes three inches apart, and five inches and a half from the snout. The outline of the body much resembles that of the Thornback, R. clavata ; snout a little prominent, the margin waved to the extremity of the expansion, behind rounded ; the eyes very small ; temporal orifices large : the body covered with rough granulations, but altogether with- out spines, either on its surface or about the eyes, except a row that runs along two-thirds of the back, and down the middle of the tail to the fins ; an irregular row of similar hooked spines extends along each side of the tail ; along the tail is a border on each side, like a membranous fin ; two rounded fins towards the end of the tail, somewhat separated, the hindmost one inch from the end, with which it is con- tinuous by means of an elevated ridge. In the distribution of its colours this is the most beautiful of the British Rays. The upper surface is a light grey, with a lighter line running along the back and middle of the tail, enclosing the central row of spines. The disk is beautifully and regularly quar- tered, first by three white lines enclosing each other, and passing from near the eye circularly to near the extremity of the expansion, the convexity of the arch inwards, and consequently the shorter line nearer the margin ; on the hinder edge of the disk, formed by the pectorals, are two. other lines passing from behind the expansion circularly to the neighbourhood of the abdominal fins, the convexity of the arch inwards ; on the more central part of the disk are a few whitish spots, those of both sides answering to each other ; the extreme edge of the disk posterior to its greatest expansion, and also the abdominals, as well as the fin-like margin of the tail, are edged with white. The nostrils have a prominent expanded membrane ; width of the mouth three inches ; teeth flat, like those of the Thornback ; mucous SMALL-EYED RAY. 435 orifices on the under surface numerous, and as if punctured with a pin ; the colour of the skin a pure white. Such is the description Mr. Couch gives of his specimen, which was a female, and which was taken by a line on the 28th of January 1835. In it numerous eggs were found, some of which had attained their full growth ; — a circumstance which fixes the period for the production of the young in this species. Montagu says both his examples were females, resembling his R. maculata in form ; Mr. Couch refers to the Thornback for shape : the figure here given is taken from Mr. Couch's drawing, and it will be observed that all three have consi- derable similarity of outline. A few extracts from Monta- gu's description will exhibit further resemblance. The pro- portions by measurement are very nearly alike ; the upper surface pale brown, with a few scattered spots and lines of a lighter colour on the margins of the wings ; the skin covered with minute spines, which make it feel rough : the eyes remarkably small, at once pointing out a material distinction ; those of the specimen described did not exceed half an inch in diameter from the opposite angles of the eyelids ; whereas the R. maculata, and most others of similar size, have eyes nearly double that diameter : one row of small hooked spines on the tail, continuing along the dorsal ridge to the head. Colonel Montagu's specimens being younger than that ob- tained and described by Mr. Couch, had not acquired the lateral marginal rows of spines on the tail ; the under part smooth and white ; the teeth obtusely cuneiform, with a broad edge that felt rough to the finger as it was withdrawn from the mouth. 436 RAIID.E.

THE THORNBACK exhibits very marked distinguishing characters, and being also a very common fish, is one of the best known of the species of Rays, — a term which Mr. Couch considers to be derived from the Anglo-Saxon ' Reoh,' which means c rough,' and is particularly appropriate to the THORNBACK. 437 Thornback, which, on the Cornish coast, is preeminently distinguished as the Ray. The Thornback is also taken com- monly both on the coast of Scotland and Ireland. From the good quality of the flesh of this fish, and the immense quan- tity taken every year, the Thornback, and its female, the Maid, is one of the most valuable of the species. Mr. Couch says that the flesh takes salt well, and in this preserved state affords the poor fishermen and their families many wholesome meals when stormy weather prevents them obtaining fresh supplies. The Thornback is taken in the greatest abund- ance during spring and summer, because the fish then fre- quent sandy bottoms in shallower water and nearer the shore than usual, for the purpose of depositing their eggs ; but the flesh of the Thornback at this season is not, as before no- ticed, so firm as in autumn and winter. It is in the best condition for table about November. Their food is various other fish, particularly Flatfish, testaceous mollusca, and crus- tacea. Bloch's figure, plate 83, represents the female of this spe- cies, under the name of R. clavata ; and the fish next in succession in that work, plate 84, is the male of the same species, but is called R. rubus, although most of the syno- nymes quoted are those of clavata. The figure here given was taken from a young male mea- suring fourteen inches in breadth. The point of the nose is but little produced : the anterior margins of the pectorals are undulated ; the outline behind each lateral angle of the pec- torals nearly straight, or slightly rounded : the eyes and tem- poral orifices rather large, with two or three strong hooked spines both before and behind them. The whole upper surface of the body rough with small points, which when examined with a lens have stellated bases. Besides these, there are dis- tributed over this upper surface numerous nail-like tubercular 438 RAHD.E. spines, each of which has an oval osseous base ; the margin of the base entire, with a central projecting crooked shank or spine directed backward. Two of these broadly-based spines occupy the central ridge of the nose ; others, to the number of thirteen or fourteen, are distributed over each side with some regularity, and similarly disposed on the two sides. The dorsal ridge of unequally-sized spines begins a short dis- tance between and behind the temporal orifices, one or two small spines occurring between each of the larger ones : this single line of spines extends to the origin of the tail, where three rows of spines begin and are continued along it, forming a series of powerful weapons. The tail is furnished with two membranous fins on the upper central ridge, and ends with a small dilatation. The prevailing colour of the upper part is brown, with numerous lighter-coloured spots, and sometimes, as has been noticed already, with one larger rounded spot on each pectoral. Young males and females have fewer spines on the body than old males, and both sexes attain some size before they put forth any ; they have frequently also but one row of spines along the tail. The colour of the under side is pure white, with a few spines only on each side. The teeth of the adult male in this species are decidedly different from those of the female, as shown in the woodcut at the top of page 416 ; those represented on the left hand being from a male fish, and those on the right from a female fish of the same size, and representing one-half of the inside of the mouth of each as seen from behind.

THIS very beautiful and well-marked species was made known by Mr. Donovan in his History of British Fishes, and a very good coloured representation of it is added in that work, which will prevent its being confounded with any other. Whether this species was really known to other authors their descriptions do not afford unequivocal proof, and I have therefore only quoted those synonymes which I know to refer to this fish. Mr. Donovan's specimen, which was not more than four inches across and seven inches in length, 440 RAIID^E. was caught on the north coast of Britain, and was commu- nicated to him by Mr. Stuchbury. Dr. Fleming, in his History of British Animals, quotes as a synonyme to radiata the R. Fullonica of the Fauna of Greenland, by Fabricius ; and it is probably a Northern species, the only three examples of it I have seen having been received, one from Berwick Bay, and two from the Frith of Forth. The first was a female, for which I am indebted to the kindness of Dr, George Johnston, and from this example the figure here given was derived. In 1835, Dr. Parnell sent me from Edinburgh two examples, a male and a female, which had been obtained in the Forth, and obligingly permitted me to retain the male for my own col- lection, which came marked accordingly. On comparing these three examples with Mr. Donovan's figure, no doubt remained that they were of the same species. The habits of this fish are but little known, and the figure here given being that of a female, I shall closely describe the male, which was nineteen inches long from the point of the nose to the end of the tail, and fourteen inches in breadth ; the snout but little produced, almost falling in with the line of the anterior margin ; the lateral expansion of the pectorals and their posterior margins rounded ; the pelvic fins rather large : the central ridge of the nose, and a great portion of the pectoral fins or wings, are covered with asperities of different sizes, but the form of which are all alike, being a single spine bent backwards, arising from a stellated base of many radii ; these appear to be nearly sym- metrical, and about equal in number on the two sides : the eyes are blue and rather large, placed about half-way be- tween the central transverse cartilaginous arch of the body and the end of the snout ; before each eye one large spine, and two large spines behind, with several smaller ones along STAREY RAY. 441 the inner edge of each eye ; temporal orifices rather large ; one large spine above the line of the transverse cartilaginous arch, one upon the centre of it in the line of the dorsal ridge, and two spines at each lateral extremity of the transverse arch : below this cross-bar commences a series of equally large spines on the dorsal ridge, which extends to the first fin on the tail; between these large spines are a few smaller ones, and on each side the central row of large spines is another row of spines about half the size of the large ones, but more numerous, forming three distinct rows down the back and tail ; but all of them, though differing in size, have the same character in respect to the beautifully radiated form of the base from which the ascending spine arises : the upper surface of the body independently of this arming is perfectly smooth; the colour pale brown, with a tinge of orange brown. On the under surface the colour is uniformly white ; the skin soft and smooth ; the nostrils large, defended by a cuta- neous valve ; the mouth rather small ; the teeth in the male with the internal angle elongated and sharp, and in a second specimen, a female of ten inches only in length, the teeth are becoming pointed. The sexual appendages in the male here described are half as long as the tail ; and as these, as well as the other sexual distinctions, are well marked in this fish, which only measures fourteen inches in breadth, I am induced to believe, from the early acquisition of these characters, that this species does not attain a very large size. This species is probably the Raia asteria aspera Rondeletii of Willughby, p. 73, pi. D. 5, f. 4, and the Raia aspera of M. de Blainville, in the Faun. Franc.; but I have not included these names among the synonymes at the head of the subject, for the want of that additional certainty which good figures would have supplied. VOL.

Generic Characters. — Head enclosed laterally by the pectorals ; posterior portion of the disk of the body somewhat rounded ; tail armed near its origin with a long and sharp flattened spine, serrated on both edges j the rest of the tail slender, without fins, and ending in a point ; teeth small. FROM the Rays whose bodies are more or less covered and protected with sharp spines supported on broad bases, and which spines, continued along the upper surface of the tail, STING RAY. 443 are defensively or offensively used, the transition to those species of Rays which are still more powerfully armed is easy and natural. The Sting Ray was well known to the ancients, who en- tertained many curious notions of the power and venom of its spine ; and this fish is also noticed as an inhabitant of the shores of this country so long ago as the days of Merrett and Sibbald. At present it is more frequently taken on the southern coast than elsewhere, from Sussex even as far west as the county of Cork in Ireland. It appears, however, otherwise to occupy an extensive range, being found in the Mediterranean, and from thence to a high degree of north latitude on the coast of Norway. Colonel Montagu, in his notes, mentions obtaining a spe- cimen, taken at Hastings, which was presented to him by the Rev. Mr. Whitear. " At the base of the bony process in the tail of this fish, was a smaller one ready to replace the original if by accident it should be lost ; or possibly this weapon may be deciduous and occasionally discharged." Mr. Couch in his MS. says, u This species keeps on sandy ground at no great distance from land, and in summer wanders into shallow water, where it is often entangled in the fishermen's nets, — the only way in which it is usually caught, for it rarely swallows a bait. The manner in which this fish defends itself, shows its consciousness of the formid- able weapon it carries on its tail. When seized or terrified, its habit is to twist its long, slender, and flexible tail round the object of attack, and with the serrated spine tear the surface, lacerating it in a manner calculated to produce vio- lent inflammation." Other authors state that it is capable of striking its weapon with the swiftness of an arrow into its prey or its enemy, when with its winding tail it secures its capture. These spines, as may be supposed, possess no really 444 RATION. venomous quality : when lacerated wounds happen to men of a bad habit of body, the symptoms are frequently very severe. In some countries, serrated fish spines, admitting of easy application by tying, are used to point arrows and spears, which when thus mounted become very formidable weapons. A specimen examined and described by Pennant was two feet nine inches long from the tip of the nose to the end of the tail ; to the origin of the tail, one foot three inches : the breadth, one foot eight inches. The body is quite smooth, except, according to M. de Blainville, a few small tubercles along the central line of the back and tail, as well as on the upper and posterior part of the pectoral fins — probably a male fish ; the shape almost round, and of a much greater thick- ness and more elevated form in the middle than any other of the Rays, but grows very thin towards the edges ; the nose is very sharp-pointed, but short ; the irides are of a gold co- lour ; behind each eye the temporal orifice is very large : the colour of the upper surface of the body is a dirty yellow ; the middle part, of an obscure blue : Mr. Donovan says the young are spotted with brown. The tail and spine are dusky ; the former very thick at the beginning: the spine, placed at about one-third of the length of the tail from the body, is about five inches long, flat on the top and bottom, very hard, sharp-pointed, the two side edges thin, and closely and sharply serrated the whole way ; the tail extends four inches beyond the end of this spine, and becomes very slender at the extremity. The under surface is white ; the nasal lobes very large ; mouth and teeth small. The flesh is said to be rank and disagreeable, and when laid bare by skinning or cutting into, is very red, — a circumstance which may account for the old name of Fire Flaire.

PENNANT, in his British Zoology, states that Mr. Tra- vis, surgeon at Scarborough, had the tail of a Ray brought to him by a fisherman of that town : he had taken it in 446 RAIIDJE. the sea off that coast, but threw away the body. It was above three feet long, entirely covered with hard obtuse tubercles, extremely slender and taper, and destitute of a fin at the end. The tail of a fish received from Sicily, and believed to have been taken from a specimen of the Eagle Ray, which is not uncommon in some parts of the Mediterranean, cor- responded with the description given by Mr. Travis. This fish is called Eagle Ray from the wing-like form of the pectoral fins ; and Whip Ray, from the long, slen- der, and flexible character of its tail. The outline near the figure of the fish represents the teeth of the upper and under jaw ; each jaw forms part of a circle ; and from a par- ticular rolling motion, added to the crushing power of these teeth, the fish has acquired the additional name of the Miller. As doubts may reasonably be entertained, the examina- tion having been restricted to a fragment, whether the Eagle Ray has really been taken on our coast, the figure of this fish, as well as that which forms the subject of the vignette, are here inserted to invite the attention of observers on the coast. To William Thompson, Esq. of Belfast, one of the Vice Presidents of the Natural History Society of that town, I am indebted for many valuable and interesting notices of the fishes of the Irish lakes and coast which are distributed in various parts of this work. In 1835, Mr. Thompson made the following communication to the Zoological Society of London, which is published in the Proceedings for that year, at page 78.

THE last family of the cartilaginous or chondropterygian fishes contains the Lampreys, and some cylindrical fishes very closely allied to them. These fishes are, in reference to their skeleton, and in some other respects, the lowest in the scale of organization among vertebrated animals. The form and peculiarities of the mouth will be best understood * The family of the Lampreys. LAMPREY. 449 by a reference to the vignette ; the figure on the left hand of which shows the flexible lip concealing the mouth ; the figure on the right hand represents the rounded mouth, the small and numerous tubercular teeth, and the central aperture lead- ing by the throat to the stomach. The situation of the branchial cells, and the gills or branchiae within these cells as they exist in the common River Lamprey, or Lampern, as it is also called, are shown in the right-hand figure at the bottom of page 326 : and the water obtains access and egress by seven small apertures on each side of the neck, by the mouth of the fish, or by an aperture through the upper part of the head which communicates with the pharynx, and which communication is distinctly seen in a divided head. The Lampreys, like the Sharks and Rays, have no swim- ming-bladder ; and being also without pectoral fins, are usually seen near the bottom. To save themselves from the constant muscular exertion which is necessary to prevent them being carried along by the current of the water, they attach them- selves by the mouth to stones or rocks, and were in conse- quence called Petromyzon, or Stone-sucker ; while the circu- lar form of the mouth induced the name of Cyclostomes, or Round-mouthed Fishes, which was bestowed upon them by M. Dumeril. In reference to the respiratory apparatus in the species of this genus, Mr. Owen has remarked,* that " when the Lamprey is firmly attached, as is commonly the case, to foreign bodies by means of its suctorial mouth, it is obvious that no water can pass by that aperture from the pharynx to the gills ; it is therefore alternately received and expelled by * Descriptive and Illustrated Catalogue of the Physiological Series of Com- parative Anatomy contained in the Museum of the Royal College of Surgeons in London, vol. ii. page 80. 450 PETROMYZIDJE. the external apertures. If a Lamprey, while so attached to the side of a vessel, be held with one series of apertures out of the water, the respiratory currents are seen to enter by the submerged orifices, and, after traversing the corresponding sacs and the pharynx, to pass through the opposite branchiae, and to be forcibly ejected therefrom by the exposed orifices. The same mode of respiration must take place in the Mix- ine," (a species of this family to be described hereafter,) " while its head is buried in the flesh of its prey. The cyclostomous fishes thus present an obvious affinity to the Cephalopoda, inasmuch as the branchial currents are inde- pendent of the actions of the parts concerned in deglutition." The intestinal canal is small, and extends in a straight line along the abdomen to the anal aperture without any convolu- tion. The Lampreys are oviparous, spawning late in the spring ; the roe escaping, in both sexes, by a small membra- nous sheath, which has internally at its base five apertures, one leading upward to the intestine, one to each kidney, and one to each lateral cavity of the abdomen. The Marine Lamprey, which from its mottled appearance was called P. maculosus by Artedi, has a very extensive geo- graphical range. It is found in the Mediterranean, and from thence northwards in most of the rivers of Europe as far as Scandinavia, during the spring. Professor Reinhardt in- cludes it among the fishes of Iceland, and our countryman Pennant gives it a place in his Arctic Zoology. From a description and figure in the Natural History of the Fishes of Massachusets, by Dr. Smith of Boston, this fish appears to be common in the rivers of North America, attaining a large size in those of the more southern states, but not ex- ceeding seventeen or twenty inches in length in a high northern latitude. Dr. Mitchell also includes this species among his fishes of New York. It is rather common during LAMPREY. 451 spring and summer in some of the rivers on the southern coast of England, particularly the Severn, and is found in smaller numbers in several of the rivers of Scotland and Ire- land about the same period of the year. I have received specimens of large size from the Severn in April and May, during which months it ascends that river to a great distance from the sea for the purpose of depositing its spawn. At this time it is considered in perfection as food, and considerable quantities are prepared in various ways for the table : the potted Lampreys and Lamperns of Wor- cester are in high estimation. A few are caught in the Thames almost every year, up which river it travels notwith- standing all the numerous and various obstacles which the port of London presents. I am indebted to my friend Mr. Broderip for a note of one taken in June 1884, and another in the same month of 1835, as high up the Thames as Sunbury Weir. A fisherman saw the Lamprey, and struck at it with his punt pole, and supposed he hit it, as the fish rose to the surface and was taken as it was swimming along. The haunt of this Marine Lamprey at Sunbury is a little above the church, and nearly opposite the vicarage, in a place called the Church Deep. In Scotland, the appearance of the Lamprey in the fresh water is rather later in the year than in the rivers of the south. Sir William Jardine says, " They ascend our rivers to breed about the end of June, and remain until the begin- ning of August. They are not furnished with any elonga- tion of the jaw, afforded to most of our fresh-water fish, to form the receiving furrows at this important season ; but the want is supplied by their sucker-like mouth, by which they individually remove each stone. Their power is immense. Stones of a very large size are transported, and a large furrow is soon formed. The P. marinus remain in pairs, two 452 PETROMYZ1D/E. on each spawning place ; and while there employed, retain themselves affixed by the mouth to a large stone." After the spawning season is over, the flesh of the Lam- prey, like that of other fish, loses for a time its firmness and other good qualities, and the weakened fish makes its way back to the sea, to recruit its wasted condition. The food of the Lamprey consists generally of any soft animal matter ; and in the sea it is known to attack other fishes even of large size, by fastening upon them, and with its numerous small rasp-like teeth eating away the soft parts down to the bone. It is not very often caught while it remains at sea. This species usually measures from twenty to twenty-eight inches in length ; the head is rounded ; the form of the body long and cylindrical, slightly compressed towards the tail ; on the top of the head, rather before and between the eyes, is an external aperture, which if examined with a blunt probe is found to pass downward and backward, opening into a tube on a line with the internal orifice of the first branchial sac : along each outside of the neck are seven rounded apertures, leading to as many branchial cells lined with a membrane constructed like that of the gills in fishes ; each of these cells has an internal opening into a tube which is closed by a car- tilaginous pericardium at the bottom, but communicates up- wards with the mouth : the lips surrounding the mouth, and the numerous small teeth within, have been already referred to : on the lower third portion of the body are two distinct membranous dorsal fins, the second of which is the most elevated, the edges of both convex ; a continuation of this membrane round the extreme fleshy portion of the tail forms a caudal fin, and a narrow slip passing upwards on the under side forms an anal fin. The skin is perfectly smooth ; the colour of the body olive LAMPREY. 453 brown, mottled and spotted on the back and sides with darker green and dark brown ; the margins of the fins in- clining to reddish brown ; the irides golden yellow. In slowly-running water, the Lamprey swims with a lateral undulating motion of the body, assisted by its fins : where the current is rapid, it makes successive plunges forward, attaching itself quickly to any fixed substance that offers to secure the advantage gained. The figure of the fish at the head of this subject was taken from an excellent drawing made by Mrs. Ley. Pennant states that it has been an old custom for the city of Gloucester annually to present his Majesty with a Lam- prey pie, covered with a large raised crust. 454 PETROMYZIILE. CHONDROPTERYG11.

THE RIVER LAMPREY, or Lampern, as it is called by fishermen for distinction, is a well-known species which abounds in many rivers of England, particularly the Thames, the Severn, and the Dee : it is also abundant in several rivers of Scotland and Ireland. Some authors state that this species, like that last described, visits our rivers in spring, and returns to the sea after spawn- ing ; but the recorded opinions of others, and my own obser- vations, induce me to believe that it generally remains all the year in the fresh water. In the Thames I am certain it is to be obtained every month in the year ; but is considered in the best condition for the table from October to March, during which time it is permitted to be caught, according to the rules adopted for the conservation of the fishery. LAMPERN. 455 Formerly the Lampern was considered a fish of consider- able importance. It was taken in great quantities in the Thames from Battersea Reach to Taplow Mills, and was sold to the Dutch as bait for the Turbot, Cod, and other fisheries. Four hundred thousand have been sold in one season for this purpose, at the rate of forty shillings per thousand. From five pounds to eight pounds the thousand have been given ; but a comparative scarcity of late years, and consequent increase in price, has obliged the line fishermen to adopt other substances for bait. Formerly the Thames alone supplied from one million to twelve hundred thousand Lamperns an- nually. They are very tenacious of life, and the Dutch fish- ermen managed to keep them alive at sea for many weeks. If this species, which is very easily obtained, be examined in the months of March or April, the distinction of the sexes will be immediately evident on opening them. The female may generally be known externally by the larger size of the abdo- men, and the male by his lips being more tumid and the mouth larger than that of the female. — The season of spawning is May, and the process has been described by several observers. This sometimes takes place in pairs only, and at others by many of both sexes occupying one general spawning bed. The food of this species, according to Bloch, is insects, worms, small fish, and the flesh of dead fish. The adult fish is usually from twelve to fifteen inches in length ; the body rather slender, cylindrical for two-thirds of its length, then compressed to the end of the tail ; the head rounded, with a single aperture on the crown, leading to the tube between the cells, as in the other species : the eye rather large ; the seven lateral openings ranged in a line behind, but a little obliquely and below it, on each side : the lip surrounding the mouth has a continuous row of small points on its margin ; the mouth and teeth as represented near the figure of the fish : the back furnished with two rather elongated 456 PETROMYZID.E. dorsal fins, with a separation between them ; the tail furnished with an extension of the membrane above and below. The skin is quite smooth, of a blue colour on the back and sides, passing into silvery white underneath. In " The Treatyse of Fysshynge wyth an Angle," attri- buted to Dame Juliana Berners, and first printed by Wyn- kyn de Worde, in his edition of the Book of St. Albans, in 1496, the learned lady, after recommending a minnow and a worm as proper baits for the Trout in the month of March, adds, " In Aprill take the same baytes : and also Juneba, other wyse named VII. eyes." Seven eyes and nine eyes, in reference to the apertures about the head, are common names for the Lamprey in this and some other countries ; but a derivation for the term Juneba is a desideratum. The vignette represents a fisherman of South Wales bear- ing his coracle ; see vol. ii. page 27. FUINGED-LIPPED LAMPEUN. 457 CHONDROPTERYGII. PETROMYZW&. THE FRINGED-LIPPED LAMPERN. PLANER'S LAMPREY.

THIS species, when adult, is easily distinguished from the Lampern last described, by its being much shorter in length, and yet equally thick in substance : it may also be recog- nised at all ages, on comparison with it, by its having the whole broad edge of the circular lip furnished with numerous papillse forming a thickly-set fringe, and by the depth and close connexion of the two dorsal fins. I am indebted to the kindness of Sir William Jardine for two specimens of the young of this species, which were sent from the Tweed. I subsequently obtained some from a brook in Surrey, which were rather larger than those sent from the North ; and have also received some specimens from Lan- cashire, the males of which measure near eight inches in length, and the females nine inches. VOL. II. 2 H 458 PETROMYZIDJE. This species was named by Bloch after his friend Planer, a professor at Erfort, who sent him specimens ; but if BlocFs species be the same as our British fish, his figure is excep- tionable. This Lampern appears to be well known to M. Nilsson, who includes it in his Prodromus of the Fishes of Scandinavia, and says it is an inhabitant of almost all the brooks and rivers of Sweden, and that it spawns in April or May. M. Nilsson gives to this fish the length of six inches only : it appears therefore that this species, like P. marinus and P. fluviatilis, does not acquire in high northern regions the size of our specimens in this country. When compared with P. fluviatilis., Planer's Lampern has the orifice on the forehead, the eye, and the first of the bran- chial apertures, much nearer the anterior edge of the lip than in the other species ; the lip broad and fringed, and the dis- position of the teeth as shown in the additional figure of the mouth only : the first dorsal fin begins about the middle of the whole length of the fish, and is in close contact with the second dorsal fin, which in its base is as long again as the first : the tail is furnished with an extension of membrane above and below, forming a caudal fin ; and a narrow slip passing forwards towards the anal sheath, forms a rudimen- tary anal fin. In its colours this species agrees with the common Lam- pern, being dusky blue on the back and sides, passing into silvery white on the belly, the fins having a brown tint. In its habits, Planer's Lampern^- so closely resembles the common Lampern, as frequently, no doubt, to have been mistaken for it. Both may go to the salt or brackish water from that part of a river within the influence of the tide. PRIDE. CHONDROPTERYGIL 459 PETROMYZIDX. THE PRIDE, AND SANDPRIDE. SANDPREY, AND MUD LAMPREY.

It is of little value, seldom exceeding six or seven inches in length, and is about as thick as a large quill. 460 PETROMYZID^E. It was formerly considered to be a Lamprey, and was called Petromyzon c&cus by Ray, on account of its very small eyes : it afterwards had the trivial name of branchialis bestowed upon it by Linnaeus, from a notion that it attached itself to the gills of fishes. It is said to be common about Oxford, and was called by Dr. Plot, in his History of Ox- fordshire, the Pride of the Isis ; Prid being an ancient dimi- nutive for Lamprey. It is very common in the Thames about Hampton, where it is called Sandpride. Mr. Jesse says the Eel is one of its greatest enemies, and feeds greedily upon it. I have received it from Hertfordshire, and some other inland counties. It spawns at the end of April or the begin- ning of May, and feeds upon worms, insects, and dead or even putrid animal matter. Mr. Couch says, " I find this species frequents our smaller streams in Cornwall, living in the muddy bottom, from which it rarely, if ever, willingly emerges. I have kept it for months in stagnant water, with mud at the bottom, without injury ta its health or activity. The only apparent use of its fins is to enable it to regain its station, when forced from it by violent torrents. When kept in clear water it seems to sleep much. I have never found this species to attach itself to any object by the mouth ; but the lips are capable of extensive and complicated motions. Our fishermen collect them to use as bait for their hooks when whiffing for Pol- lacks." The upper lip and the mouth in this species, as shown in the enlarged representation of the lower surface of the head under the figure of the whole fish, is in the form of a horse- shoe; the inner part furnished with numerous short and slender membranous cirri ; " the lingual and palatine plates somewhat harder than the other portion, but no true teeth :" on the top of the forehead is a small orifice and canal, which PRIDE. 461 leads to the internal tube between and connected with each lateral set of branchial cells, as in the Lampreys ; the eye is very small, so much so as to have been occasionally over- looked, and it is situated at the bottom of a small and deep depression : the branchial apertures are seven on each side, arranged along a kind of lateral groove : the body of the fish at this part is rather tumid ; behind this the form of the body is nearly round, the portion beyond the anal opening com- pressed : there are two dorsal fins, the first short and low, the second longer and higher, with a distinct diminution between it and the first dorsal fin, and also with the dilated membrane forming the caudal fin, which is somewhat round- ed, the fleshy portion of the tail being pointed ; a narrow slip of membrane forms an anal fin. Some variations occur in specimens of this fish from differ- ent localities, and there is even reason to suppose that two species may exist. The most frequent colour is yellowish brown, approaching to blackish brown on the top of the head and upper part of the back, much lighter underneath and on the fins. The vignette was copied from a sketch of a fishing party made by T. Stothard, R.A. about the year 1780. PETROMYZID.E. CHONDROPTERYGII. PETROMYZIDX. THE MYXINE. GLUTINOUS HAG, AND BORER.

THE worm-like form of the fish figured above induced several systematic authors, including Linnaeus, to class it with the Worms ; and it was not till after dissections and published descriptions that its true relations with the Lam- preys were acknowledged. Of these memoirs, that furnished to the French Institute in 1797 by Bloch, the ichthyologist MYXINE. 463 of Berlin, will be read with interest ; and the substance of it will be found in the twelfth part of his valuable work on Fishes, in which the internal structure is rendered obvious by various coloured illustrations. In the family of fishes now under consideration, the last of vertebrate animals, the spinal column is in a rudimentary condition. In the Lampreys it is but indistinctly divided into rounded portions. In the Myxine, in place of a series of bones composing the vertebral column, there is merely a soft and flexible cartilaginous tube ;* while in the diminutive fish next to be described, which is the last of the British species, this support is reduced to a small and slender semi- transparent column, extending throughout and connecting the whole length of the body like the flexible horny pen in some species of Cephalopods, and to which class other rela- tions of structure both in the Myxine and in this small fish will be pointed out. As a British fish, the Myxine occurs most frequently on the eastern coast. It enters, says Pennant, " the mouths of other fish when on the hooks attached to the lines which remain a tide under water, and totally devours the whole except the skin and bones. The Scarborough fishermen often take it in the robbed fish on drawing up their lines." On this part of our coast it is called Hag, and also Borer, because, as others say, it first pierces a small aperture in the skin, and afterwards buries its head in the abdomen or body. It is most usually found in the body'of the Cod, or some other equally rapacious fish. For the only specimens of the Myxine I ever possessed, I am indebted to the unremitting kindness of Dr. George Johnston of Berwick, who has assisted me most materially * If a section be made, a probe passes readily in either direction. 464 PETROMYZID.E. by sending me examples of many interesting species which have been referred to throughout this work. The Myxine is not uncommon at Berwick ; but it is only to be obtained at a particular season of the year in one or two particular localities, when during fine weather, at the end of spring or the beginning of summer, the fishermen lay their long lines on a bank with a soft mud bottom near that coast when fishing for Cod and Haddock. It is considered by some that the Myxine, which is without eyes, obtains access to the interior of the body of the fish by passing in at the anal aperture ; others endeavour to account for its being found in the belly of a voracious fish by supposing it had been swallowed ; while many experienced fishermen still repeat their belief that the Myxine enters the mouth of the Codfish while it is hanging on the line. It is conjectured that the Myxine does not fasten upon any fish unless it be either dead or entangled on a hook : but how a fish that is blind is able to find its way to a particular aperture, is a matter not easily explained. .The eight barbules or cirri about the mouth of the Myxine are, there is no doubt, delicate organs of touch, by which it obtains cognizance of the nature and quality of the substances with which they are in contact ; and its single hooked tooth upon the palate en- ables it to retain its hold till the double rows of lingual teeth are brought into action to aid the desire to obtain food. The high northern geographical range of this singular fish is shown by M. Nilsson including it among the fishes of the shores of Scandinavia, where, he adds, four and even six examples have been found within the body of one Had- dock, the flesh of which was entirely consumed. The Myx- ine is oviparous, and the ova are of the same colour, size, and form as those of the Lampern, — that is, small, round, and yellow. MYXINE. 465 Along the whole length of the under surface of the body, from head to tail, there are two rows of mucous pores, from which a large quantity of a gelatinous secretion is expressed occasionally at the will of the animal, and by which, either in reference to its quality or quantity, or both, this fish is said to escape its enemies. So copious and so thick in its consistence is this jelly-like secretion, that some of the older naturalists believed this fish had the power of converting water into glue, and it obtained in consequence the name of the Glutinous Hag. The body is elongated, eel-like in form, cylindrical throughout the greater part of its length, tapering and com- pressed towards the tail ; the whole length from twelve to fifteen inches ; the skin perfectly smooth and unctuous ; the head obtusely pointed, with a single spiracle connected with the interior of the mouth and branchiae ; eyes wanting ; eight tentacula, cirri, or feelers, as they are called, are placed about the lips, four near the front, and two on each side ; lips soft, extensible, inclining to a circle in their figure ; one single hooked tooth on the palate ; the tongue fur- nished with four rows of small pointed teeth, two rows on each side : at the division between the thoracic and abdo- minal cavities are two external apertures, each of which is connected by a membranous tube with the six branchiae on its own side ; hence Blocks name of Gastrobranchus. The anal aperture is an elongated fissure situated about two inches before the end of the tail ; along the whole under surface of the body are ranged two rows of pores, which afford egress to the secretion of the numerous glands within ; the dorsal fin is low and rudimentary, except towards the tail, where the membrane is dilated, and being continued round the end of the tail, and thence upwards to the anal aperture, forms in addition a caudal and an anal fin, which 466 PETROMYZID.E. no doubt materially assist this fish in swimming. In colour the Myxine is dark brown along the back, lighter chestnut brown on the sides, and yellowish white underneath. The vignette here added is from a drawing by Mr. Clift, engraved for the Philosophical Transactions for the yeaj 18] 5, where it illustrates a paper by Sir E. Home on the organs of respiration in the Lamprey and Myxine. The upper angle of the figure exhibits the single spiracle, about it the eight tentacula, on the centre of the palate the single hooked tooth ; to the right and left are the double rows of lingual teeth : an inch below, on each side, are the six branchial cells, with their internal communications with the central canal ; on the outside each cell communicates with a tube that is common to the six cells on that side, which, passing downward, ends at the external aperture below. Beneath this is the stomach and intestinal canal, which, as in the Lamprey, is straight ; the rounded marks along the margin on both sides from end to end show the numerous mucous glands that have already been referred to. It is impossible to dissect a Myxine, and attend to the structure and substance of its investing skin, without being forcibly reminded of its great resemblance to the investing mantle of the Cephalopods. The relations of structure in the Myxine to the Lampreys on the one hand, and the first class of mollusca, the Cepha- lopods, on the other, appear to prove that the situation claimed for this fish by Bloch, and systematic authors since his time, is the natural one. The relation to the Lampreys is shown in the elongated, cylindrical form of the body ; the single spiracle on the head ; the general similarity in the parts of the mouth ; the character of the branchial cells, and the viscera. The relation to the Cephalopods is apparent in the eight MYXINE. 467 tentacula or feelers about the head, the horny but flexible nature of the columnar support of the body, the character of its external covering, and by the power of ejecting a copious secretion whenever it considers itself in danger. 468 PETROMYZIDJE. CHONDROPTERYG11. PETROMYZIDM. THE LANCELET. Amphioxus lanceolatus, YARRELL. Umax „ PALLAS, Spic. Zool.X. p. 19, t. i. fig. 11. Generic Characters. — Body compressed, the surface without scales, both ends pointed ; a single dorsal fin extending the whole length of the back ; no pec- toral, ventral, anal, or caudal fins ; mouth on the under part of the head nar- row, elongated, each lateral margin furnished with a row of slender filaments. THE singular little animal here figured of the natural size, although one of the smallest, as well as the last, among British fishes, is by no means deficient in interest. The specimen, the only one I ever saw, and which is probably also the only one that has been taken for many years, was sent to me by Mr. Couch, who found it himself on the shore near Polperro. A portion of the tail of this little fish was sticking out from underneath a stone in a small LANCELET. 469 pool left by the tide. Mr. Couch perceiving it, took it up with some water in the hollow of his hands. It was alive, very active, and so transparent that the viscera were perceivable through the external covering. It was taken home by Mr. Couch, who made a drawing of its appearance under a mi- croscope. The only notice of this little animal on record that I have become acquainted with is that by Pallas, in his Spicilegia Zoologica, already quoted ; and I insert at the foot of the page, as a note, the Latin description of Pallas,* believing that the reader will then have before him all that has been published of this very rare little animal, of which, at least as far as I am aware, possibly no other specimen has been found or noticed since that to which Pallas refers, and which, it is not a little singular, was also obtained from Cornwall. Of the specimen in his possession Pallas says, " Quod nunquam vivum vidi, sed liquore servatum e mari Cornubiam adluente accepi olim, quodque prima facie refert piscem Leptocephalum Gronovii." At first sight this little fish has somewhat the appearance of a Leptocephalus, a British fish first sent to Gronovius by our countryman and zoologist Pennant ; it more par- ticularly resembles it in the arrangement of the strise on the flattened sides : but Leptocephalus, as will appear by a reference to the figure of it in this volume at page 311, has a perfect head, though a small one, with jaws, teeth, * " Limax lanceolatus. Corpus anceps, planum, linear! lanceolatum, utrin- que acutissimum. Margo undique limbo membranaceo auctus ; subtus vero ad duas tertias longitudinis margo bilabiatus est, sulcatusque, ut sit quasi pes limacinus angustissimus. Tentacula plane nulla. Latera striis obsoletis, antrorsum obliquatis prope dorsum angulo recurvatis, ut quasi latus pisciculi desquamatum referant." 470 PETROMYZID/E. eyes, and gill-covers ; while the fish under consideration has neither eyes nor gill-covers, nor any fins except one along the back. Supported by the opinions of three or four zoological friends, I have placed this little animal in this family, near the cyclostomous fishes, believing it to be, as far as at present known, the lowest in organization among this class ; and although I am unwilling to mutilate entirely by my rough dissection the only specimen probably I shall ever possess, and which is perhaps unique, I shall yet be able to show, by the figures given and some further description, that this animal is entitled to a place at the end of the present family. The form of the fish is compressed ; the head pointed, without any trace of eyes ; the nose rather produced : the mouth on the under edge, in shape an elongated fissure, the sides of which are flexible ; from the inner margin ex- tend various slender filaments, regularly disposed, which cross and intermingle with those of the opposite side. Along the sides , of the body the muscles are arranged in regular order, diverging from a central line, one series passing ob- liquely upward and backward, the other series as obliquely downward and backward : the anal aperture is situated one- fourth of the whole length of the fish, in advance of the end of the tail ; the tail itself pointed : from the nose to the end of the tail a delicate membranous dorsal fin extends the whole length of the back, supported by very numerous and minute soft rays ; the surface of the body smooth. The body is strengthened and supported internally throughout its length by a flexible cartilaginous column, from which the numerous muscles diverge ; the cavity of the abdomen is comparatively large ; the intestine a canal of LANCE LET. 471 considerable calibre, without convolution ; above it a double row of flattened globular bodies, which have all the appear- ance of ova. The figure at the top of the illustration re- presents this fish of the natural size. The right-hand figure in the middle line is an enlarged representation of the mouth as seen from below, with the filaments from each side stretching across the opening ; the outline on the left of the middle is a magnified view of the two portions of the hyoid or lingual bone, to which the filaments are attached, one branch of which bone is divided, and the cut portions turned up and down to expose the other perfect side ; the figure at the base is a magnified view of the appearance of the whole fish. Several relations in structure to the Lampreys and Myx- ine are observable in the fringed mouth, the armed lingual bone, the absence of eyes, and the want of pectoral and ventral fins. Of its habits, that only which has been stated is known : it is extremely active when in water, and its food is probably some of the most minute among the thin- skinned Crustacea, or decomposing animal matter. It may perhaps be expected that I should state on what grounds I have ventured to differ from such a naturalist as Pallas in considering this animal a fish, and not a Limax. It is distinguished from the Limaces by the absence of the ventral muscular disk for locomotion ; and from every other molluscous genus, in the position of the anal aperture, which is unconnected with the respiratory cavity. On the other hand, the dorsal fin, and regular oblique strata of muscular fibres clothing the sides of the body and having their points of origin attached to a firm dorsal internal axis, — with the existence of a lengthened internal vertebral column, although in a soft cartilaginous state, as in the Myxine, — are sufficient 472 PETROMYZID.E. to determine the primary division of animals to which the Amphioxus belongs.
