This Goby, though described from Mr. Jenyns"' work, was not figured in the former volumes of the British Fishes. It has probably been long confounded with Gobius minutus, but is more slender, and otherwise distinguished. It was first described by the Rev. Leonard Jenyns in his Manual of the British Vertebrate Animals, from specimens obtained on the coast of Essex. Dr. Parnell says, " This well-marked Goby is occasionally found in the Firth of Forth, but is not com- mon ; it inhabits the same situations as the mimitus, and they arc frequently taken together. I have found it in the Sol way Firth, and in much greater plenty on the southern coast of England. It spawns in June, and is of little value except as food for other fishes and aquatic birds." Mr. Jenyns' description is as follows : — " Length, three inches two lines. Form closely resembling the minutus, but more elongated and slender throughout ; greatest depth barely one-seventh of the whole length : snout ratlier longer : opercle approaching more to triangular, the SLENDER OOnv. 23 lower anrrlc being more cut away, and tlio asccmling margin more oblique ; a larger si>ace between it and the pectorals : tlic two dorsals further asunder : rays of the second dorsal longer ; these rays also gradually increasing in length, instead of decreasing, the posterior ones being the longest in the fin, and rather more than equalling the whole depth : rays of tlic anal in like manner longer than in G. 7ninutus. The fin-rays in number are — I). 6. 12 : P. 21 : V. 12 : A. 12. : C. 13, and two short rays. In all other respects similar. The colours also resembling those of minutus, with the exception of the anal and ventral fins, which are dusky, approaching to black in some places, instead of plain white, as in the ininutus.''''

Gobius vnipu7ictatiis, One-spotted Goby, Parnell, Memoirs of the Weinerian Nat. Hist. Soc. vol. vii. p. 243. This Goby, says Dr. Parnell, " does not appear to have been noticed by previous authors. I have observed it in most of the sandy bays in the Firth of Forth ; but in greater numbers, and of larger size, in the neighbourhood of the salmon-nets above South Queensferry, "where it may be found throughout the summer months in water from two to three feet deep. I found it on the south coast of England, equal- ly common with the Gobius mimitus^ or Freckled Goby. I have also found it in many situations where the mimitus was not seen ; and the minutus has been taken in many places where the iinipunctalus did not exist. The most northern locality in which it has yet been observed appears to be the Moray Firth, where James Wilson, Esq. obtained a fine specimen of three and a half inches in length." " This fish, although closely allied to the other species of the same genus, is undoubtedly quite distinct from them ; the black spot on the first dorsal fin being far more constant and ONE-SPOTTED OOBY. 25 conspicuous than any character wliich distinguishes the rest of the British Gobies. The only species it can well be mis- taken for is the G. minutus, but differs from it in having a black spot between the fifth and sixth ray of the first dorsal fin ; the second dorsal with eleven rays, and the tail fin even at the extremity. Whereas the G. minutus has no black spot between the fifth and sixth ray of the first dorsal fin ; the rays of the second dorsal ten in number, and the tail fin rounded at tlic end." A specimen, two inches and a half in length, is thus de- scribed by Dr. Parncll. " Body rather elongated, rounded in front, compressed at the tail ; flattened on the nape ; head long in proportion to its depth, one fourth of the length, in- cluding half the caudal rays ; operculum and preoperculum rounded. Colour of the head, back, and sides, pale brownish yellow ; throat and belly white ; dorsal and caudal fins freckled and barred with pale brown ; first dorsal fin with a black spot between the two last rays, which assumes a beau- tiful appearance when newly taken from the water ; lateral line crossed by six or seven dark spots, the one at the base of the tail being most conspicuous. First dorsal fin with fine flexible spiny rays, of which the second and third are rather the longest, commencing behind the base of the pectorals, and ending in a line over the end of the pectoral rays ; se- cond dorsal fin remote from the first, commencing in a line over the vent, and ending over the last ray of the anal ; the anterior rays longer than the terminal ones ; all flexible and branched, except the first, which is simple ; anal fin similar to the second dorsal, leaving a wide space between its termi- nation and the base of the caudal rays ; ventral fins united so as to form but one fin ; the middle rays the longest, extend- ing to the vent ; each ray is branched except the first and last, which are very short and simple ; between each is stretched a membrane, forming the base of the ventral disk. 26 GOBIOID.E.

Cobius atbiis, The While Gohu, I'arnell, Transactions of the Royal Society of Edinburgh, vol. xiv. This species of Goby, Dr. Parnell observes, " holds sucli a conspicuous place in the genus, that it cannot well be mis- taken for any other. I first noticed it in the Solway Frith, in June 1836, where I obtained in one day, after the recess of the tide, fifty specimens. They are evidently the fry of a large species. When first taken from the water they are soft and transparent ; the eyes are large and prominent ; the scales which cover their body are large, thin, and very deciduous. The length is about two inches ; the head is large ; the gape is wide ; the teeth are long and sharp, placed in a single row in each jaw. The first dorsal fin commences over the ante- rior third of the pectorals ; the second dorsal fin commences over the vent, and ends opposite to the base of the last anal rays. The cheeks are tumid ; the border of the operculum rounded ; the body is transparent, and marked by a number of fine depressed lines, placed in an oblique direction; the lateral line is straight throughout its length. The number of the fin-rays are — D. 5. 13 : P. 16 : V. 13 : A. 13 : C. 12. 28 GOBIOID.E. The last ray of the anal and second dorsal fin is longer than the first, and reaches, when folded down, to the base of the tail rays. These fishes are supposed (erroneously) by the fishermen to be the young of the Sting-fish, Trachinus vi- pera, and are consequently destroyed whenever they come within their reach. On transferring them to a bottle of alco- hol they lose their transparent aspect, and become hard and opaque. In the month of July, when I had occasion to re- visit the Solway Frith, I endeavoured to obtain additional specimens, presuming that by this time they would have somewhat increased in size ; but not a single specimen could be found, nor has the parent fish ever come within the obser- vation of the fishermen. " The first dorsal fin of this fish, as possessing but five rays, is sufficient to distinguish it from every other British species of the same genus." The teeth in this species are also more formidable in pro- portion to the size of the fish than those of any other British Gobv. JAOO S C.OLDSINN Y. 29 A CA N THOPTER YGII. I.A BRIDGE.

Fries and Ekstrom, Scandinavian Fishes, pt. ii. pi. 3, fig. 1. In the month of February 18S6, Dr. George Johnston ob- tained three specimens of the Luljanns rupeslris of Blocli, two of which were picked up in Berwick Bay, and the third near Barnclcugh ; these specimens were thrown on shore after 30 LABRIDE. a violent storm, and having been sent by Dr. Johnston to his friend Mr. Selby, became the subject of a notice in the first volume of the Magazine of Zoology and Botany, as quoted under the figure of the fish here given. This fish Mr. Selby most correctly referred to the Gold- sinny of Jago, in the Synopsis of our countryman and natu- ralist John Ray, who appears to have been the first to make it known ; but this fish being also a northern species, was afterwards figured and described in the various works here quoted among the synonymes. Since the occurrence of the specimens on our eastern coast, Mr. Thompson of Belfast has obtained two others at Bangor, County of Down, where they were caught, with one or tAvo other species of Wrasse, by angling boys. 1 have received from T. S. Rudd, Esq. two beautifully coloured examples of this fish, which were taken on the Yorkshire coast, from the finest of which the figure here engraved was drawn ; one specimen has also been taken on the coast of North Wales by my friend Mr. Tho- mas Eyton. Among some Lahri supplied me by Mr. Couch from Cornwall, before the occurrence of the specimens in Berwick Bay, was a small fish of this species, but being by accident somewhat discoloured and distorted, and this species differing in colour when young, I did not recognize it as the Lutj'anus rupestris of Bloch, but figured it as a vignette to the Scale-rayed of the British Fishes, vol. i. p. 300. Since that time Mr. Couch has very kindly supplied me with more small specimens, which will enable me to describe this fish as it appears at different stages of its growth, premising, how- ever, that I have seen no examples of more than seven inches in length. This species is taken occasionally in the Baltic ; in Swe- den, Denmark, and Norway, where it is sometimes caught by angling from rocks, as in this country. Another coloured figure of this fish has recently appeared in the new work of JACOBS GOLDSINNY. 31 MM. Fries and Ekstnim, on tlic Fishes of Scandinavia, now in course of publication, in parts, at Stockholm. The length of the specimen here described was six inches and a half. The length of the head one inch and- three ([uar- tcrs ; the diameter of the eye three eighths and a half, or one fourth of the length of the head ; the irides silvery ; the teeth, long, strong, curved, and pointed, particularly in the anterior part of the upper jaw ; both preoperculum and opercu- lum covered with scales ; the preoperculum distinctly crenated throughout the greater part of its ascending edge ; the dorsal and pectoral fin commence on the same vertical line ; the membrane connecting the first four spinous dorsal rays black; the spinous rays shortest at the commencement of the fin, becoming gradually, but slightly, more elongated towards their union with the soft rays, and in length about equal to one fourth of the depth of the body of the fish ; the soft rays more lengthened ; from the base of the last of which to the end of the caudal rays, is about the same length as that of the head, and about one fourth of the whole length of the fish. Half way between the base of the last soft dorsal ray and the extreme end of the caudal rays, there is on the upper edge of the body and tail a conspicuous roundish black spot, equally visible on either side ; the caudal fin-rays scaled from their base on a line with this black spot halfway along, the ends of the caudal rays slightly rounded ; the anal fin with three spiny rays, and ending with elongated soft rays, the base of the last of which is a little in advance of the base of the last soft dorsal ray in a vertical line ; the ventral fin begins a little behind and below the base of the pectoral fin ; the pectoral is in length, compared to the length of the fish, as one to seven. The prevailing colour in the largest specimen is orange, the free edge of each scale being of a light golden yellow ; the colour is darkest over the three or four lines of scales along the highest part of the back, and diH LABRIDE. lightest on the lower part of the sides and belly ; the body is also indistinctly marked with five transverse bands, the first of which descends from below the more anterior spinous rays of the dorsal fin, and the fifth from below the elongated soft rays of the dorsal fin ; but I have never seen these bands near so strongly marked as they are made to appear in Bloch"'s coloured figure, the ground colour of the body of which re- sembles that of one of my specimens. Young examples of this species are of a uniform yellowish flesh colour ; the fins still lighter ; but the black spot at the commencement of the dorsal fin, and on the upper part of the base of the tail, are very conspicuous from the uniform paleness of the body and fins generally, and, but for these two constant spots, are not unlike the Labrus pusillus of Mr. Jenyns, as figured in this Supplement. These spots appear to be good distinctions ; very young specimens of Crenilabrus cornubicus, which in the British Fishes should have been called the Corkwing, are constantly marked with the spot on the middle of the side of the tail, in specimens measuring only one inch and a half in length. The fin-ray formula in Jago"'s Goldsinny is — D. 17 + 9'-. P. 14 : V. 1 -f 5 : A. 3 -I- 7 : C. 13. The number of scales along the lateral line is thirty-two, and four or five more extend along the basal half of the rays of the caudal fin ; there are four rows of scales between the lateral line and the dorsal ridge, and eleven rows of scales between the lateral line and the anal aperture. M. Nilsson says, this species is liable to variations in co- lour, and some of the species taken in Northern localities are tinged with green. rORKMNf!. S3 ACANTHOPTERYGII.

This species, of which no examples more than four inches in length have been as yet recorded, was obtained by Pro- fessor Henslow at Weymouth, and four or five specimens are now preserved in the Museum of the Cambridge Philoso- phical Society. I possess one which was sent me by Mr. Couch from Cornwall ; and Mr. Thompson of Belfast has recorded the occurrence of three others, which Avere taken at Youghal in Ireland, by Mr. Ball, in the summer of 1835. These last specimens were characterised by Mr. Thomp- son in the Proceedings of the Zoological Society for 1837, page 56 — not without some hesitation — as a new species, under the name of Crenilahrus multidentatus ; but subse- quent comparative examinations of the specimens of the two countries, appear to show that they are identical, and they are here therefore brought together. 34 LABRID.E. Mr. Jenyns'' description of a specimen, four inches in length, is as follows : — " Distinguished by its small size. Back but little elevated, sloping very gradually towards the snout ; ventral line more convex than the dorsal ; sides com- pressed : depth contained about three times and three quar- ters in the entire length ; thickness half the depth, or barely so much ; head one-fourth of the entire length : snout rather sharp ; jaws equal : teeth of moderate size, conical, regular, about sixteen or eighteen in each jaw : eyes rather high in the cheeks, situate half-way between the upper angle of the preopercle and the margin of the first upper lip ; the space between about equal to their diameter, marked with a de- pression ; a row of elevated pores above each orbit : preoper- cle with the ascending margin very oblique ; the basal angle, which falls a little anterior to a vertical line from the poste- rior part of the orbit, very obtuse, and remarkably charac- terised by a few minute denticulations, which further on be- come obsolete, and in some specimens are scarcely anywhere obvious : lateral line a little below one-fourth of the depth ; nearly straight till opposite the end of the dorsal, then bend- ing rather suddenly downwards, and again passing off straight to the caudal ; number of scales on the lateral line about forty-five : dorsal commencing at one-third of the length, excluding caudal ; spinous portion nearly three-fourths of the whole fin, the spines very slightly increasing in length from the first to the last, which last is not quite one-third of the depth of the body ; soft portion a little higher than the spi- nous, of a somewhat rounded form, the middle rays equalling nearly half the depth : anal commencing a little anterior to the soft portion of the dorsal, and terminating a little before it ; the first three rays spinous, the third being the longest, but the second the stoutest spine ; soft rays resembling those of the dorsal : caudal nearly even, with rows of scales be- tween the rays for nearly half their length: pectorals rounded. CORKLINO. 35 about two-thirds the length of the head, immediately beneath the commencement of the dorsal ; all the rays soft and arti- culated, and, except the first, branched : vcntrals a little shorter ; the first ray spinous, shorter than the second and third, which arc longest ; all the soft rays branched ; the last ray united to the abdomen by a membrane for half its length.

" It is apparently," says Mr. Jenyns, " quite distinct from any of those described by other authors.

Soon after the publication of the British Fishes, Mr. Conch very kindly supplied me with two examples of this Small-mouthed Wrasse, a species Avhicli I had not till then seen, and which on the Cornish coast is called the Rock Cook, where it is not so common as the Cork wing {Creni- labrus Cornuhicus)^ nor does it take a bait like that fish, but is generally caught in the pots set for crabs. Since that time Mr. Thompson has recorded the occurrence of this spe- cies in two northern localities in L'eland, at Cairnlough in SMALL-MOUTHED AVRASSE. 37 the county of Antrim, and at Lough Foyle in tlic county of" Lonilondcrry. At tlic former phice the fish was found by Dr, Drummond, and at both places by Captain Portlock. Altliough tliis fish was most appropriately called micro- stoma^ for it may be immediately distinguished when among other Crcnilabri by this very obvious peculiarity, it proves to be a species long known to more northern naturalists. JNIr. Thompson has given a coloured representation of this fisli in the second volume of the Magazine of Zoology and Botany, as previously quoted, and the recent publication at Stockholm of another coloured figure in the second part of the Fishes of Scandinavia, by MM. Fries and Ekstrom, leave no doubt of the two fishes being the same, and enable us to identify our species as the Lahrus exoletus of Linna?us. It is a fish of small size, seldom exceeding four inches or four inches and a half in length, and is taken occasionally on the coasts of Sweden, Denmark, and Norway, and, according to Fabricius, as far north as Greenland, Avhere, however, it is said to be rare. The specimen from which the figure and description Avere taken, measured four inches in length, and one inch and one quarter in depth ; the length of the head compared to that of the whole fish, is as one to four, or rather less. This species exhibits a sliffht elevation over the eve in the line of the frontal profile ; the figure here given marks the true position and relative length of the various fins. The teeth are flat, even, and incisor-like, with the corners slightly rounded ; some liffht-colourcd lines extend from the mouth to the orbit, and over part of the cheek ; the irides are silvery ; the colour of the head and body is dark brown on the upper part, passing into pale wood-brown underneath, and on the sides and belly; the colour of the dorsal, caudal, and anal fins dark brown; the pectoral and ventral fins lighter; and my specimens having been many months preserved in spirits 88 LABRID/E, have lost some of the lighter tints which the coloured figure of Mr. Thompson's fish, and that also of MM. Fries and Ekstrom exhibit. The formula of the fin-rays is — D. 19+ 6 : P. 13 : V. 1 -f- 5 : A. 6 +7 : C. 12, and 2 shorter rays. The number of Scales forming the lateral line are thirty- two, with four rows above to the dorsal edge, and eleven below to the anal aperture.

I AM indebted to Mr. William Brandon of Chancery Lane for a fine specimen of this fish which was sent me in the year 1836 from Dagcnham in Essex. Mr. Brandon who is the renter of the waters at Dagenham Breach, so well known to the London anglers, and who has frequently favoured me with examples of other species from this loca- lity, having taken this Bream in his net with other fish, very kindly sent it to mc Avith a note stating that it differed from the Bream he had usually caught in that water ; and finding when he reached home and made closer examination, that it did not accord Avith the characters of either of the Bream figured and described in the British Fishes, he begged my acceptance of it, hoped it might prove of some interest, and requested to know what it was. I understand from Mr. Brandon that he has since at different times taken from twenty to thirty of the same sort. 40 CYPRINID.F,. The cliaracters of this species are so decided, that I had no difficulty in identifying it as the Cj/prinus Biiggenhagii of Bloch ; and on the next visit to London of my friend William Thompson, Esq. of Belfast, who has devoted such unwearied attention to the Zoology of Ireland, I found that he had also obtained an example of the same species of Bream from the river Lagan, near Belfast, which circum- stance was made public in the printed Proceedings of the Zoological Society for 1887, page 56, as already quoted. This species of Bream is at once distinguished from either of the two species which have been hitherto found in this country, by the greater thickness of its body, which is equal to half its depth ; while in either of our other Bream the thickness of the body is only equal to one third of its depth ; the scales of this species are also larger in proportion, although the figure here given, not having been drawn on a comparative scale with them, does not exhibit this j^eculiarity. The anal fin is shorter and has a smaller number of rays than that of Abramis blicca, Avhich in its turn has its anal fin smaller, and with fewer rays than that of Abramis vulgaris, which is the Bream most generally known in this country. This new species was first described by Bloch from speci- mens found in Swedish Pomerania, in the river Pene, and in the lakes communicating with it. The specimens were sent to Bloch by M. Buggcnhagen, and hence the trivial name which has been devoted to it for specific distinction. I have also called it the Pomeranian Bream, considering it no ob- jection to attach to this fish the name of the country in which it was first discovered, although it may happen to have been afterwards found elsewhere. The fish attains to the length of twelve_or fourteen inches in that country according to Bloch; the flesh is white, but not much in request on account of the number of small bones which are found in it. It is taken in the same manner and by the same means as the common PO.MKRANIAN UKKAM. 41 Bream ; and Bloch reports that tlic (islicrmen are greatly pleased when they talce this fish in their nets : they have learned by experience that when this Bream appears they shall have a succcssfal fishery : they believe that the other Bream follow this fish, and the name they have accordingly bestowed upon it in that country signifies guide or conductor. Except in Bloch I do not find this species included in either of the works I possess, or have yet gained access to, which treat of the fresh-water fishes of the different countries of the continent of Europe. The specimen of this fish from Dagenham, from which the following description Avas taken, measured fifteen inches in length, of which the head was three inches, or, compared to the whole length of the fish, as one to five ; the depth of the body a little in advance of the line of the first ray of the dor- sal fin, Avhere the body is deepest, five inches, or one third of the whole length ; the thickness of the body two inches and a half, equal to half the depth, or one sixth of the whole length ; the head is rather small and pointed, the mouth is also small ; the diameter of the eye about one fifth of the length of the head, the iris silvery and about the same breadth as the pupil ; the operculum rather large and angu- lar; the pectoral fin rather small; half the ventral fin, in advance of a vertical line falling from the origin of the first dorsal fin ray ; the dorsal fin commences exactly half way be- tween the point of the nose and the end of the caudal fin ; but the base of the dorsal fin in this fish is longer than the base of the same fin in either of our other species of Bream ; the anal fin is shorter than that of the shortest of the other Bream, and has three rays less ; it is also less falcate in form, or more equal in the Icngtli of its rays ; the tail in shape at its posterior edge rather lunate, tlie outer rays elongated ; the formula of the fin rays is D. 12 : P. 17 : V. 9 : A. 19 : C. 19 : Veitebiic 41. 42 CYPKINID.E. The number of punctured scales forming the lateral line fifty-two ; from the anterior edge of the dorsal fin to the lateral line, following the oblique direction of the scales, there are eleven scales ; from the lateral line downwards to the base of the pectoral fin, four scales, not including in either enumeration the punctured scale of the lateral line itself. Upper part of head and back dark blackish blue, becoming lighter on the upper part of the sides, and passing into silvery white on the lower part of the sides and belly ; pectoral fin, dorsal fin and tail, bluish brown, tinged with pale red ; ven- tral and anal fins with less brown and more pale red.

Hemiramphus Europmis, Etinri)ean Ilemiiamphiis, Mag. Nat. Hist. 1837, p. 505. In a valuable communication on the Fishes of Cornwall, made to the Linncan Society some years ago by Jonathan Couch, Esq. of Polpeno, which was published in the four- teenth vohniie of the Transactions of that Society, the author thus expresses himself in reference to a small fish which ap- peared to be a species of the genus Hemiramphus : — " I have met with a species which I have never seen described, unless it be the Esox Brasiliensis Linn. Si/st. Nat. (Hemi- ramphus Brasiliensis Cuv.) It was taken by me in the harbour at Polperro, in July 1818, as it was swimming with agility near the surface of the water. It was about an inch in length, the head somewhat flattened at the top, the upper jaw short and pointed, the inferior jaw much protruded, being at least as long as from the extremity of the upper jaw to the back part of the gill-covers. The mouth opened ob- liquely downwards ; but that part of the under jaw which protruded beyond the extremity of the upper, passed straight forward in a right line with the top of the head. The body was compressed, lengthened, and resembled that of the Gar- pike, Esox be/one. It had one dorsal and one anal fin, placed far behind and opposite to each other. The tail was straight ; the colour of the back was a bluish green, with a few spots ; the belly silvery." 44 ESiOCID.E. In August 1837, Dr. Clarke of Ipswich favoured me with a letter, of which the following is an extract : — " My brother, Mr. Edward Clarke of Ipswich, who is particularly interested in the study of British fishes, was examining the sea-shore in the vicinity of Fclixtow, a village in Suffolk, between Har- wich and Orford, a few days ago, August T'th 1837, when he observed a shoal consisting of myriads of small fish, which, upon a nearer examination, he supposed to be the young of the Garfish. As he had previously not found any so small, he secured a few specimens ; and, upon bringing them home and examining them, they were found not to be the young of the Garfish, but those of a species of Hemiramphus. From their being so very young, it probably may be difficult to determine whether they belong to a described species ; but from the circumstance of their haviuQ- been seen in ffreat abundance in a small pool left by the retiring tide, it is, I think, pretty evident that the ova must have been deposited and vivified in the neighbourhood of our shores. I send you the fish, thinking that an examination of the specimens them- selves will be far more satisfactory than any figures or descrip- tion of my own. One specimen was taken about double the size of those now sent to you." The representation of this fish is half as large again as the natural size. It can scarcely be doubted from the quantity of fry seen, as well as from their very small size, that the spawn from which they were produced must have been deposited on our shores by the parent fish ; and yet, as far as Ave are aware, these parent fish have hitherto escaped capture. This might not appear very extraordinary ; but from the circumstance that the size attained by the fry in the months of July and August, as well as the general simi- larity in the form and appearance of the Heviiramphus to our well-known Garfish and Saury-pike, would lead to the be- lief that the Hemiramphus visited our shores about the same EUROPEAN HKiNlIRAMrHIfS. 45 time of the year as these lishes. The (iiuflsh appears on the coast in April, and spawns in May ; the Saury-pike makes its first appearance in June. For tliese fish, but particu- hirly for the former, nets are worked on various parts of the coast, and considerable (piantities arc taken ; but no adult specimens of Hemircnnplius, unless we are to suppose they have remained hitherto unrecognised by the fishermen. It is also not a little singular, that up to the present time, with the exception of the small specimens already referred to, as taken at two places very distant from each other, no ex- ample of any species of Hemiramphus has been found, either in the Mediterranean, the Channel, or in the North seas. I have lately had an opportunity of conversing with two emi- nent foreign naturalists, to whom I showed the specimens, who agreed with me that no adult species of Hemiramphus had been recorded as found in the seas of Europe. One question may be hazarded, — Is this fish, with its une- qually developed jaws, the very young state of our common Garfish (Belone vulgaris)? Except in the peculiarity of the mouth, it is certainly very like it ; but our young Garfish of the year taken in December, when they are about seven inches long, specimens of which I possess, have the upper jaw of the same comparative length as the lower one. Another season or two will probably decide the question, and it will be as interesting, in an ichthyological point of view to be able to determine this to be the young state of Belone as that there exists a true Hemiramphus in the seas of Europe. The two examples obligingly sent me by Dr. Clarke, are too young and too minute to make any attempt to define specific characters desirable, beyond such as the remarks of Mr. Couch, and the representation here given will supply ; and I only propose, for distinction's sake, that it should be called Hemiramphus Europaus. 46 ESOCID.E.

In a Cornish Fauna, by Jonathan Couch, Esq. ■which has recently been published for the Royal Institution of Corn- wall, Mr. Couch has included a species of Flying Fish which threw itself on to the Quay at Plymouth, and the specimen is still preserved. From an inspection of this example Mr. Couch was enabled to determine that it was the Greater Fly- ing Ffsh, Exocatus extliens, or Le Muge volant of Bloch, the well-known species of the Mediterranean ; and Mr. Couch adds, that he has reason to believe, from the dimensions as GREATER FLYING FISH. 47 given to lumbytlic possessor, that the individual Flying Fish which was found at Helford, where it was discovered on the sand, having just then expired, w'as of the same species. This specimen, which is in the possession of Mr, John Fox of Plymouth, measures sixteen inches in length. The elongated ventral fins, placed very far backwards, readily serve to distinguish this fish, which has long been well known in the Mediterranean, and was, I believe, first figured by Belon in the year 1553, by Rondelet in his Latin edition in 1554, and in the French edition printed at Lyons in 1558. For the general habits of the Flying Fish, the reader may consult the first volume of the History of British Fishes, page 398. Bloch says that the Greater Flying Fish attains the length of eighteen inches ; and the specimen from which the representation in the work of Duhamel was taken, measured sixteen inches, Bloch says this fish is found in the Red Sea as well as in the Mediterranean. Our countryman Wil- loughby saw it in Calabria. Rondelet states that it is found in quantity at the mouth of the Rhone, and Duhamel mentions that, besides being plentiful in the Mediterranean, it had also been taken in the ocean. The flesh of this fish is rich, and is said to be more delicate than that of the herring. The head is wide and flat on the top, but somewhat angu- lar underneath ; the mouth is small, the lower jaw rather longer than the upper ; both jaws arc furnished with pointed teeth, those in the lower jaw being the smaller of the two ; the eyes arc large, the irides silvery, the pupil dark blue ; the nostrils large, and placed rather nearer to the eye than to the point of the nose ; the operculum has the appearance of polished steel ; the body of the fish is covered with large scales, which adhere but slightly ; the upper part of the body is a fine blue colour, the lower part silvery white ; the lateral line is placed very low down and runs throughout its whole length, but lit- tle above, and parallel to, the ventral profile ; the pectoral 48 fins are very large and of a fine transparent blue colour ; the ventral fins long, and almost rounded at the end ; the dorsal and anal fins are falcate, beginning and ending nearly on the same plane ; the tail consists of two unequally sized lobes, of M'hich the lower lobe is the larger. The fin ray formula, ac- cording to Bloch, is B. 10: D. 11: P. 18: V. 6: A. 12: C. 22. According to M. Risso, the female is heavy with roe in the spring, and is remarkable for the variations that occur in the number of the rays of her fins. w r M END OF THE SUPPLEMENT TO THE FIRST VOLUME.

Salino satar, AurroiiUM, British Fishes, vol. ii. p. I. Since the publication of tliat part of the History of British Fishes Avhich contains an account of tlie Sahnon, JMr. John Shaw of Drunihmripf, Dumfriessliirc has printed in the Edinburgh New Philosophical Journal for July 1836 and January 1838, detailed particulars of various interesting and valuable experiments, made by himself, on the developc- ment and growth of the fry of the Salmon, froni their ex- clusion from the ova to the age of seven months. Three ponds, varying in size, one eighteen feet by twcnty- VOL. II. B 2 SALMONII>.E. two, the second eighteen feet by twenty-five, and the third thirty feet by fifty, were prepared at a convenient distance from a Salmon river, (the Nith,) the ponds two feet deep, thickly embedded with gravel, and supplied from a small stream of spring water, in which the larvae of insects were abundant. The distance from the river to the ponds is stated as rather less than fifty yards, a proximity, it is ob- served, " sufficient to place the young fish confined in them on a similar footing with those in the river, so far as situa- tion is concerned. The average temperature of the water is also nearly the same in both ; that of the rivulet, however, being rather higher and less variable than that of the Nith.*" The experiments were conducted with great care. The ponds being prepared, the next object was to secure the fish, the progeny of which were to form the subject of observation. " With the view, therefore, of securing two Salmon, male and female, while engaged in the performance of the act by which the species is propagated, Mr. Shaw provided himself with an iron hoop five feet in diameter, on which he fixed a net of a pretty large mesh, so constructed as to form a bag nine feet in length by five feet in width. The hoop and net were then attached to the end of a pole nine feet long, thus forming a landing net on a large scale. The weight of the net with its iron hoop being upwards of seven pounds, it in- stantly sunk to the bottom when thrown into the water." " Being thus prepared with the means of carrying his ex- periment into execution, Mr. Shaw proceeded to the river Nith on the 27th January 1837, and readily discovered a pair of adult Salmon depositing their spawn. Before pro- ceeding to take the fish, he formed a small trench in the shingle by the edge of the stream, through which he directed a small current of water from the river two inches deep. At the end of this trench was placed an earthenware basin of considerable size, for the purpose of ultimately receiving the SALMON. O ova. The fish wore then, at one instant, both enclosed in the hoop, and allowed to find their way into the bag of the net by the aid of the stream. Having drawn them ashore, tlie tcniale, while still alive, was placed in the trench, and a quantity of the ova pressed from her body. The male was then placed in the same situation, and a quantity of the milt being pressed from his body, passed down the stream, and thoroughly impregnated the ova. The spawn was then transferred to the basin, and deposited in the stream of the feeder to the first pond. The temperature of the stream was 40 deg., and that of the river from which the Salmon were taken 36 deg. The skins of the parent Salmon were pre- served and exhibited, that no doubt as to the species might be entertained. The weight of the male when taken was six- teen pounds, and that of the female eiglit pounds." Without following Mr. Shaw through the details on this, as on three or four other occasions, it may be sufficient to state, that the young fish ruptures the external capsule of the ovum, or may be said to be hatched in about 114 days when the temperature of the water is 36° 101 ,, „ ,, „ 43° 90 ,, ,, ,, ,, 45° When first emerging from the membrane within which the young fish has been enclosed, the remains of the yolk or vitelline portion of the ovum is still attached by its own capsule to the abdomen of the fish as represented in the figure No. 1, which is taken from a specimen given me some years ago by Sir William Jardine. The remains of the yolk supplies nourishment to the young fish till it is able to take food by the mouth. Mr. Shaw has ascertained that the yolk is absorbed in twenty-seven days. At the end of two months the young fish is one inch and one quarter long, and the figure No. 2 is from Mr. Shaw's representation. At the end of four months the young fish measures two inches and a half b2 ^ SALMONID.E. in length, and at the end of six months it had attained the length of three inches and three quarters. From these experiments Mr. Shaw infers, that the growth of the young of the Salmon has been much overrated ; that as the young Salmon in its progress assumes at a certain age the markings and colour of the Parr ; that the Parr, as a dis- tinct species, does not exist ; and finally, that the young of the Salmon do not go down to the sea till they are more than twelve months old at the least, that is sometime during their second year, if not still later than that. That the young of the Salmon, from their particular ap- pearance at a certain age, have been constantly called Parrs, I readily admit ; but so have also the young of two other migratory species, S. trutta and S. eriox ; T think, there- fore, that this is not conclusive evidence of the non-existence of a distinct small fish, to which the name of Parr ought to be exclusively applied ; it rather shows the want of power among general observers to distinguish between the young of closely allied species, three or four of which are indiscrimi- nately called Parrs. That the rate of growth in the young of the Salmon has been exaggerated may be very true ; but the rate of the growth of the fry in Mr. Shaw*'s ponds cannot be expected to equal that which would have taken place in the open river. Circumscribed in space over which to roam, and limited in food, as to variety at least, if not in quantity, in small ponds, the growth would be retarded in proportion ; and this cir- cumstance seems proved by Mr. Shaw''s own remark, in which he states that the fish in the third pond (the largest pond of the three) " were considerably larger than those in the first pond, the difference in length at the age of six months amounting to an inch, or more than one fifth. That the young fish do not go down to the sea till their second year, I am willing to believe on Mr. Shaw''s authority. SALMON. O because he has devoted great attention to the subject, and has for years had opportunities for observation which give great weight to his opinion. I have thus purposely adverted to tlie experiments of Mr. Shaw on account of their great interest, merit, and value ; and because I am now enabled, through the kindness of Thomas Lister Parker, Esq., to offer a continuation of remarks on the growth of the Salmon in fresh water, which illustrate and confirm some of the views of Mr. Shaw ; and in order to prevent any misconception of the terms employed, I shall speak of the young Salmon of the first year as a Pink ; in its second year, till it goes to sea, as a Smolt ; in the autumn of the second year as Salmon Peal, or Grilse, and afterwards as adult Salmon. In the autumn of the year 1885, Thomas Upton, Esq. of Ingmire Hall, situated between Sedbergh and Kendal, be- gan to enlarge a lai^e on his property, and in the spring of 1 836, some Pinks from the Lune, a Salmon river which runs through a valley not far from the lake, were put into it. This lake, called Lillymere, has no communication with the sea, nor any outlet by which fish from other waters can get in, or by which those put in can get out. The Pinks when put into Lillymere did not certainly weigh more than two or three ounces each. Sixteen months afterwards, — that is, in the month of August 1837, Thomas L. Parker, Esq. then visiting his friend, fished Lillymere, desirous of ascertaining the growth of the Pinks, and with a red palmer fly caught two Salmon Peal in excellent condition, silvery bright in colour, measuring fourteen inches in length, and weighing fourteen ounces. One was cooked and eaten, the flesh pink in colour, but not so red as those of the river ; well flavoured, and like that of a Peal. The other was sent to me in spirit of wine, and a drawing of it immediately taken. In the month of July 1838, eleven months after, another small Salmon was caught, equal to the first in condition and colour. 6 SALMONID.E. about two inches longer and three ounces heavier. No doubt was entertained that these were two of the Pinks transferred to the lake in the spring of 1836, the first of which had been retained sixteen months, and the other twenty-seven months, in this fresh-water lake. Desirous of ascertaining the appearance of the young Salmon at periods intermediate between the states as Pinks and Salmon Peal, other experiments were tried. Pinks in the river Hodder in the month of April are rather more than three inches long, and are considered to be the fry of that year : at this time, Smolts of six inches and a half are also taken. The smolts are considered as the fry of the pre- vious year, and are distinguished by the blue colour on the upper half of their body, the silvery tint of the lower half, and the darker hue of the fins generally as compared with those of the Pink. In this state as to colour, the Smolts are said to have assumed their migratory dress and go down to the sea in May. In June the young Pink in the Hodder measures about four inches ; in July it measures five inches, and no Smolts are then found in the river. To be further convinced of this change, and the length of time required to produce it, a Pink put into a well at Whitewell* in the forest of Bowland in November 1837, was taken out in the state of a Smolt of six inches and a quarter in July 1838. In another instance more Pinks by Mr. Upton's directions were put into Lillymere in September ] 837, and Mr. Parker caught five or six in the state of Smolts of seven and a half inches in August 1838. In referring to the par- ticular size of the Pinks in the river Hodder at stated periods, it may be necessary to remark that the Pinks of different rivers, and even in the same river, will be found to vary in size, depending on the time at which the spawn was deposited, the temperature of the season, and other causes. * For a view of Whitewell, see British Fishes, vol. ii. p. 88. SALMON. 7 I may here observe tliat I am indebted to the kindness and liberality of Thomas Lister Parker, Esq. for a variety of specimens, as well as for the requisite information concerning tlicm. Of the various fishes, when received, accurate drawings were innucdiately made, and coloured representations of six examples at ditfercnt ages, in illustration of this subject, are in preparation, and may be had distinct from this supple- ment. A knowledge of the growth of young Salmon in a fresli- water lake, as here described, and the experiment has suc- ceeded elsewhere,* may be useful to those gentlemen who possess lakes near Salmon rivers from which they can supply them with Pinks : whether the Salmon thus prevented going to salt water will still retain sufficient constitutional power to mature their roe, and by depositing it in the usual manner, as far as circumstances permit, produce their species, would be a subject worthy of further investigation. That the rate of growth in young Salmon has some reference to the size of the place to which they are restricted, as hinted when de- scribing Mr. Shaw's experiments, receives further confirma- tion in these river, lake, and well specimens. The Sniolt taken from the well in July 1838, where it had been con- fined for eight months, was rather smaller in size at that time than the Smolts in the Hodder in the preceding April, though both were Pinks of the same year, namely ISoT. The Smolt taken from the lake in August 1838, which then measured seven inches and a half, had also grown more rapid- ly than that in the well, but had not acquired the size it would have gained had it been allowed to go to sea. Further, it may be observed, that the Salmon Peal from the lake in August 1837, then eighteen months old, though per- fect in colour, is small for its age; while that of July 1838, or twenty-nine months old, is comparatively still more defi- ' Sue Biitibli fishes, vol. ii. j).

In March 1839, Mr. Upton put six dozen Charr from Windermere into his lake. The vignette represents the bones of the head in the Salmon. LOCHLEVEN TKOUT ABDOMIXAL MAI.ACOI'TEKYGll. SALMOMD^.

I AM indebted to Dr. Parnell for the loan of a beautiful specimen of this Trout from Avhich the figure was taken, and the following account of it by Dr. Parnell is from the seventh volume of the Memoirs of the Wernerian Natural History Society of Edinburgh. " This fish is considered by most writers on British Ich- thyology to be identical with Sahno Jario, the common Trout, differing from it only in the colour of the flesh, and in having no red sjjots on the sides. It is true that food and season may have a great share in diminishing or increasing the external markings and colour of the flesh ;* but they can have no effect in shortening or lengthening the rays of the fins, or in adding numbers to the csecal appendages."

S. cacifer has never any red spots ; S. fario is scarcely ever without them. The caudal rays are much longer in cacifer^ than in fario, in fish of equal length. In S. cacifer the tail fin is pointed at the upper and lower extremities; in aS*. yar«o they are rounded. The flesh of aS*. cacifer is of a deep red, that of S. fario is pinkish and often white. The csecal appendages in S. ccccifer are from sixty to eighty in number ; in S. fario I have never found them to exceed forty-six." " Lochleven (of which the barren isle and now dismantled castle are famous in history as the prison-place of the beauti- ful Queen Mary) has long been celebrated for its breed of Trout. These, however, have fallen off of late considerably in their general flavour and condition, owing, it is said, to the partial drainage of the Loch having destroyed their best feed- ing ground, by exposing the beds of fresh-water shells, the animals of which form the greater portion of their food.* They spawn in January, February, and March." " The fish described does not appear to be peculiar to this Loch, as I have seen specimens that were taken in some of the lakes in the county of Sutherland with several other Trout, which were too hastily considered as mere varieties of S. fario. It is more than probable that the Scottish lakes produce seve- ral species of Trout known at present by the name of S. fario, and which remain to be further investigated." Dr. Richardson, who has had opportunities of examining very fine specimens of this celebrated Trout, considers it dis- tinct from S. fario, and has pointed out some of the differ- ences "between them : the scales are thick, and when dry * There are two or three varieties of S.fdrii) in liOchleven with white and ])inkish flesh, which are much inferior in flavour to 6'. cacifer. — Encyc. lirit.

Three in- dividuals of the Lochleven Trout dissected by Dr. Richardson had each seventy-three pyloric cseca, and in one of them fifty- nine vertebrse were counted. The largest of the specimens measured twenty inches and a quarter, including the caudal fin, and two inches less to the end of the scales. Dr. ParnelFs description, taken from a specimen measuring one foot in length, is as follows : — " Head rather more than one-fifth of the whole length ; caudal fin included ; depth be- tween the dorsal and ventral fins less than the length of the head.

"^^^^^ THE GREAT LAKE TROUT, OR GREAT GREY TROUT. Saliiw fernx, Jaudine and Selby, and Britisli Fishes, vol. ii. p. 60, Since tlie publication of the History of British Fishes, in which the existence of tlic Great Lake Trout in Lough Neagh, was recorded as ascertained by Mr. Thompson of Belfast, that gentleman, following up his zoological re- searches, has learned that this fish exists in Lough Corrib, in the county of Gahvay, and also in Lough Erne, in the county of Fermanagh, thus proving it, to use Mr. Thomp- son's words, to be an inhabitant of the three largest lakes in Ireland, and it Avill probably yet be found in most of the lakes of any considerable extent in that country. Mr. Thompson has very kindly supplied me with a young fish of this species from which our representation was taken, and which, differing from specimens of large size in having the spots more numerous, may be an acceptable addition. As mentioned in the former volume, this Lake Trout, when small, is in Ireland called a Dolachan ; when large a Buddagh, and they are usually caught on night lines baited with a perch or a pollan. The mode of taking this fish in J 4 SALMONID.E. tlie large Lochs of Scotland is given in tlie second volume of the British Fishes, page 6^. I have reason to believe that tliis same species of Great Grey Trovit is an inhabitant of some of the large lakes of Scandinavia. Sir Thomas Maryon Wilson, Bart, visited Sweden last sum- mer, ascending the Gota river in his yacht, the Syren, and passing through the celebrated sluices of Trollhattan, cruised and fished in Lake Wenern, visiting his friend Mr, Lloyd, who resides near the southern extremity of this noble lake. Sir Thomas M. Wilson brought back with him five or six skins of the Great Trout of the lake, which were caught by spinning with a bleak, and must, from their large size, have afforded some excellent diversion. The largest of these specimens measured forty-two inches in length, and weighed about thirty-four pounds : the next largest v.eighed thirty- two pounds : the third twenty-seven pounds, besides others of smaller size. These large Trout, and larger than these are seldom seen, are observed to be males ; the females, accord- ing to Mr. Lloyd, Avho has lived for some years on the borders of the lake, rarely exceed twenty or twenty-two pounds. The number of fin rays in these specimens averaged D. 13: P. 14: V. 9: A. 11: C. 19. Among other fish taken by Sir Thomas Wilson, was a large specimen of the Ide, Leuciscus idus of authors. This fish, which resembles our English Chub, was caught in the Gotha Elf, a short distance above the falls of Trollhattan, whilst trolling for pike on a windy day : its Aveight was between four and five pounds. The skins of these various specimens were effectually preserved and mounted after they were brought to England. Sir Thomas M. Wilson did me the favour to show me his numerous sketches of scenery, taken during this trip, which include views of the Gota river, the cities and country on its GREAT LAKE TROUT. 15 banks, tlic celebrated fiills of Trollhattan and parts of Tiake Wenern at different points of view ; very kindly allowing mc the use of a coloured drawing from which the vignette below, on a reduced scale, was taken. This view represents Mr. Lloyd's cottage on the eastern bank of the Gota ; the yaelit of Sir Thomas Wilson lying at anchor immediately opposite ; with the remarkable and finely wooded hills of Hunneberg and Halleberg, so much celebrated for the peculiarity of their geological structure, bounding the distance. ^ 16 SALMONID.E.

I AM indebted to Mr. William Euing of Glasgow for the opportunity of making known a new species of Smelt which that gentleman did me the kindness to send to me in the month of November 1837. This fish is at once clearly dis- tinguishable from our long-known and highly-esteemed fa- vourite, the common Smelt, and is the more interesting from the circumstance of its being — at least, as far as I am aware — entirely new to Ichthyology. Mr. Euing passed part of the summer of 1837 near Rothsay in the Isle of Bute ; and the Smelt in question was brought to him by a fisherman, who stated that he caught it on a hand line in the bay of Roth- say, about two hundred yards from the shore, in twelve fathom water ; that it was, though well known, but rarely seen. This specimen measured six inches and a half; but another example of the same sort, measuring eight inches in length, "that was taken near the same place in June 1836, was full of roe, and when first caught the cucumber-like smell, so peculiar to the Smelt, was in this species also very apparent. IfEBRIDAL SHIELT. 17 Unable to find any notice of a second species of Smelt in Europe in any Tclitliyolof;;ical work "witli which T am acquaint- ed, I have little doubt that this fish has not been previously described ; and in reference to the locality in which alone it has been as yet taken, I have ventured to name it the Smelt of the Hebrides, Osmerus Hehridicus. The specimen sent me by Mr. Euing, measuring six inches and a half in length, is one inch and one eighth deep at the commencement of the dorsal fin, at which part the body is deepest ; the thickness of the body compared to the depth is as one to two, or exactly half: the length of the head is one inch and three eighths, and is, in reference to the whole length of the head and body, without the tail, as one to four. The jaws are nearly equal in length, without teeth upon either ; but there are four long teeth upon the tongue ; the eye is very large, the diameter almost equal to one third of the whole length of the head, and placed at a distance of little more than its own diameter from the point of the nose : the upper surface of the head is flattened, descending by a rapid slope to the nose ; the line of the low'er jaw straight ; the pos- terior edge of the operculum rounded ; the back of the fish, or its dorsal outline, slightly arched ; the abdominal line nearly straight ; the sides compressed. The dorsal fin commences lialf way between the point of the nose and the anterior edge of the adipose or rayless dorsal fin, the longest ray nearly twice the length of the base of the fin ; the last dorsal fin ray but three, the same length as the base of the whole fin. The adipose fin is placed very near tlie tail ; the tail itself deeply forked. The pectoral fin peaches to the plane of the com- mencement of the dorsal, and its length, if turned forwards, would reach to the centre of the eye. The ventral fin is in a vertical line under the last ray of the dorsal fin ; there is a slender axillary scale ; but the ends of the ventral fin rays being injured, the length of the fin cannot be mentioned. VOL. II. C 18 SALMONID.E. The anal fin has its last ray underneath the posterior edge of the adipose fin ; but the rays of the anal fin are also broken. The formula of the fin rays is as follows : — D. 11 : P. 14 : V. 12 : A. 12 : C. 19. The scales are large and deciduous, the lateral line promi- nent and nearly straight. Below the lateral line for the whole length of the body two rows of the scales are silvery white, forming a conspicuous elongated band, like that to be observed in the Atherine,* the rest of the body and fins dull amber colour, the gill covers silvery and iridescent. The figure of our well-known common Smelt is inserted as a vignette to exhibit the comparative characters of the two species. * British Fishes, vol. i. p. 214. i«^ i^mm 19 AIWUMIXAL MALACOFTEliVGIl.

Dr. Parnell, whose Ichthyological investigations in Scotland have not been confined to tlic " Fislies of the Forth,"'' only, has described in the first volume of the Annals of Natural History a .si)ecies of Coreirouus, to which he has attached the name of Laccpedci, this species having been fir.st noticed, or perhaps distinguished, by this celebrated French naturalist. 'J'his fish is found in Loch Lomond, one of tlic largest and most picturcstpie lakes in the west of Scotland. It is not unlikely that some of the species of Congoni found in the northern lakes of England, Scotland, and L'cland, may exist in the lakes of Scandinavia, M. Nilsson, Professor of Natural History at Lund, describing in his Prodromus Ich- thyologidi Scandinavicfc no less than eight species as belong- ing to that country ; but from a certain general agreement in e .^ 20 SALMONlD,E. the characters of the Corcgoni, it is difficult to refer our species with certainty in the absence of foreign specimens with which to make actual comparison. It appears, on reference to his Natural History of Fishes, that Lacepede became aware of the existence of this Coregotnis in Loch Lomond by the communication of M. Noel, who visited Scotland in August 1802. Although some little differences appear in the descriptions of this fish, as given by Lacepede and Dr. Parnell, there is little doubt that both authors had the same species under consideration. This fish bears, as observed by Dr. Parnell, considerable resemblance in appearance and also in the number of its fin-rays to the Sahno War t ma mil oi JMoch, part 3, tab. 105, a species of Cor^egojius, named after a learned physician, who first de- scribed it. It is found in some of the lakes of Switzerland, and also in lake Constance ; but Lacepede, to whom the Wartmamii was known, considered the Loch Lomond Core- gonus distinct. It is thus described by Dr. Parnell, from a specimen fourteen inches in length. " Head long and narrow, of an oval form, about one-fifth the length of the whole fish, caudal fin included ; depth of the body between the dorsal and ventral fins less than the length of the head. Colour of the back and sides dusky blue, with the margin of each scale well defined by a number of minute dark specks; belly dirty white ; the lower portion of the dorsal, pectoral, ventral, and anal fins dark bluish grey; irides silvery, pupils blue. First ray of the dorsal fin com- mencing half-way between the point of the snout and the base of the short lateral caudal rays ; the first ray simple, the rest branched ; the second and third the longest, equalling the length of the pectorals ; the seventh ray as long as the base of the fin ; the last ray one-third the length of the fourth ; adipose fin large and thin, situate midway between the base of the fourth dorsal fin-ray and the tip of the long I'OW.VN. 21 upper ray of the caudal fin ; anal fin coninicncing half way between the origin of the ventral fin and the base of the middle caudal ray ; the first ray simple, the rest branched ; the second ratlirr tlu' longest ; the third as long as the base of the fin ; the last ray half the length of the fifth ; ventral fins commencing under the middle of the dorsal ; the third ray the longest, equalling the length of the same ray of the dorsal ; pectorals long and pointed, one-sixth the length of the whole fish, caudal fin included ; the first ray simple ; the second and third the longest, the last short, not one-fourth the length of the first ; tail deeply forked, with the long rays of the upper portion curving slightly downwards, giving the fin a peculiar form. Gill cover produced behind ; the basal line of union between the operculum and suboperculum oblique ; the free margin of the latter slightly rounded ; pre- operculum angular ; snout prominent, somewhat of a conical form, extending beyond the upper lip ; jaws of unequal length, the lower one the shortest. The maxillary bone broad, the free extremity extending back to beneath the an- terior margin of the orbit. Teeth in the upper jaw long and slender, aboiit six in number ; those on the tongue shorter and more numerous. Eyes large, extending below the mid- dle of the cheeks ; lateral line commencing at the upper part of the operculum, and running down the middle of the sides to the base of the middle caudal ray. Scales large and de- ciduous, eighty-four forming the lateral line, eight between the dorsal fin and lateral line, and the same number between the lateral line and the base of the ventrals." The numbers of the fin-rays, including the two short rays at the com- mencement of the dorsal and anal fins, are D. 14 : P. 16 : V. 12 : A. 13 : C. 20 : caeca 120. " This fish grows occasionally to the length of sixteen inches. In the stomach of one of the specimens examined 22 SALMONID.E. were found several species of Entomoslraca^ larva of insects, a few Coleoptera, a number of small tough red worms, little more than half an inch in length, and about the thickness of a coarse thread, besides a quantity of gravel, which the fish had probably accumulated when in search of the larva."" " These fish are found in Loch Lomond in great numbers, where they are called Powans or Freshwater Herrings. They are caught from the month of March until September with large drag-nets, and occasional instances have occurred in which a few have been taken with a small artificial fly : a minnow or bait they have never been known to touch. Early in the morning and late in the evening large shoals of them are observed approaching the shores in search of food, and rippling the surface of the water with their fins as they pro- ceed. Li this respect they resemble in their habits the Vcn- dace of Lochraaben and the saltwater herring. They arc never seen under any circumstances in the middle of the day. From the estimation these fish are held in by the neighbour- ing inhabitants, they are seldom sent far before they meet with a ready sale, and are entirely unknown in the markets of Glasgow. Li the months of August and September they are in best condition for the table, when they are con- sidered well flavoured, wholesome and delicate food. They shed their spawn in October to December, and remain out of condition until March." Although agreeing in the number of fin-rays with the Pollan of L'cland, this Loch Lomond fish is at once dis- tinguished from it by the peculiar form of its mouth, a repre- sentation of which, in two points of view, inserted as a vig- nette, and contrasted with the same parts in the Pollan, both of the natural size, will, better than description, convey the appearance in proof of distinction. The Loch Lomond fish being remarkable for the depth of the upper lip, and the large size of the lateral free portions of the superior-maxillary bones. POM" AN. 23 Dr. Parncll lias ilcscribod a second species of Corrgoniis fouml in Loch Loniond, which differs from tlie first in having a smaller head, yet agreeing exactly in the number of all the fin-rays ; but as I learn by communication with Dr. Parnell that since the publication of his paper he has obtained many specimens from Loch Lomond, the characters of which are intermediate in reference to the two fishes described, and appear to connect them, I have not figured it as a distinct species. 24 SALMONID.E.

A SHORT notice of tlie Pollan of Ireland, as made known by Mr. Thompson of Belfast in 1885, was inserted in the History of British Fishes, vol. ii. p. 88 ; and that gentleman having most zealously followed up his zoological investiga- tions in that country, I am now enabled to add from his re- searches various further particulars. " The earliest notice of the species that I have seen," says Mr. Thompson, " is in Harris's History of the County of Down, published in the year IT^i, where, as well as in the statistical surveys of the counties of Armagh and Antrim, it has subsequently been introduced as one of the fishes of Lough Neagh, under the name of Pollan : but, as may be expected in works of this nature, little more than its mere existence is mentioned." " The habits of this fish do not, with the exception of its having been in some instances taken with the artificial fly, TOLL AN. S5 difFcr in aiiv marked respect from those of the Vcndace of Scothmd or the (iwyniad of Wales, and arc in accordance Avith such species of continental Europe as arc confined to inland waters, and of whose history wc have been so fully in- formed by Bloch. The Pollan approaches the shore in large shoals, not only during spring and summer, but when the au- tumn is far advanced. The usual time of fishing for it is in the afternoon, the boats returning the same evening. On the days of the 23rd, 24th and 25th of September 1834, which I spent in visiting the fishing stations at Lough Neagh, it was along with the common and great lake trout, Sahno fario and Sahno fcrox, caught plentifully in sweep-nets, cast at a very short distance from the shore. About a fortnight before this time, or in the first week in September, the greatest take of the Pollan ever recollected occurred at the bar-mouth, where the river Six-milc-water enters the lake. At either three or four draughts of the net, one hundred and forty hundreds, — one hundred and twenty-three fish to the hun- dred,*— or 17,220 fish were taken; at one draught more were captured than the boat could with safety hold, and they had consequently to be emptied on the neighbouring pier. They altogether filled five one-horse carts, and were sold on the spot at the rate of 3s. M. a hundred, producing 23/. 6s. 8cL From 3.s'. 4(/. to 4s. a hundred has been the ordinary price at the lake side, or directly from the fishermen; some years ago it Avas so low as Is. 8(1. the hundred, but at that time the regular system of caniage to a distance, as now adopted, did not exist. At the former rates thcv arc purchased by carriers, who convey them for sale to the more populous parts of the neighbouring country, and to the towns within a limited distance of the lake. They are brought in quantities to Belfast ; and when the supply is good, the cry of ' fresh pollan' prevails even to a greater ex- * The Englisli long hundred is six score, or one liundred and twenty. ^b SALMONID^E. tent than that of ' fresh herring,"* thougli both fishes are in season at the same period of the year. In the month of June 1834, fifty hundreds, — six thousand one hundred and fifty individuals — of pollan and one hundred and twenty-five pounds weight of trout were taken at one draught of a net, at another part of the hake near Ram's IsLand, Avliich was the most succeesful capture made there for twenty-four years. In 1834 this fish was more abundant than ever before known. Like the Gwyniad and Vendace, the Pollan dies very soon after being taken from the water, and likewise keeps for a very short time. It is not in general estimation for the table, but is, I think, a very good and well-flavoured fish." "Though permanently resident, the pollan is very far from being generally diffused throughout Lough Neagh. It rarely occurs between the river Mayola and Toone ; while from the Six-milc-water to Shane''s Castle is so favorite a resort, that a few houses that formerly stood near the latter locality, were dignified with the name of Pollan 's Town." " In the months of November and December this fish de- posits its spawn where the lake presents a hard or rocky bot- tom. On the 4th of December 1835, a quantity of the largest Pollans I have seen were brought to Belfast market. Several were thirteen inches in length, and all on dissection proved to be females just ready to deposit their roc. On the 11 til of the same month several male specimens of full size that I procured, and which contained milt most promi- nently developed, measured but eleven inches and a half, — thus showing that in maturity the female fish exceeds the male in length in the proportion of thirteen to eleven and a half. Its average weight when in season is about six ounces. One specimen, mentioned to me as the largest taken within the last ten years, weighed two pounds and a half. The only food that I have, without resorting to the microscope, detected in the stomach of the Pollan was a full grown speci- TOLL AN. 27 men of the bivalve sliell Pisidiion pulclielliim. A pcl)])]e of equal size was also found with it." In the stomach of a specimen given me by Mr. Thompson I found a species of Gammarus. ^Ir. Thompson, in some more recent examina- tions, has found mature individuals of Gammarus aqualicus, and the larva? of various aquatic insects ; some shells of the genus Pisidium, one of the fry of the three-spined stickleback, and a few fragments of stone. Others were found to contain minute JUntomostraca, two Pisi'dia, and a Li'mneiis pereger, this last Avas three lines in length. Besides inhabiting Lough Neagh, the Pollan has also been found in Lough Derg, an expansion of the Shan- non ; and Lord Cole, who has most condescendingly in- terested himself in the History of British Fishes, had the kindness to send me ajar full of Pollan from Lough Erne in the county of Fermanagh, from one of which specimens our figure was taken. The Pollan of Lough Erne are rather deeper for their length than those of Lough Neagh. His lordship has also sent me two species of Charr from L-cland ; some from Lough Eask being identical with the Charr of the Cumberland Lakes, while those from Lough Melvyn are short and deep fish with large fins exactly resembling the Charr found in two or three lakes in Wales, the particulars of both of which are described in the second volume of the British Fishes. To return to the Pollan of L-eland, Mr. Thompson's de- scription is as follows : " The relative length of the head to that of the body is about as one to three and a half; the depth of the body equal to the length of the head ; the jaws equal in length, both occasionally furnished with a few delicate teeth ; the tongue with many teeth ; the lateral line sloping downwards for a short way from the operculum, and thence passing straight to the tail. Nine rows of scales from the dorsal fin to the lateral liiu', and the same number thence to SAIiMONID.E. the ventral fin, the row of scales on the back and that of the lateral line not included. The third ray of the pectoral fin the longest. The fin-ray formula is as follows — B. 9 : D. 14 : P. 16 : V. 12 : A. 13 : C. 59 : vertebra 59. Of these, the first two rays of the dorsal fin, and the first two rays also of the anal fin are short. " The colour to the lateral line dark blue, thence to the belly silvery ; dorsal, anal, and caudal fins, towards the ex- tremity, tinged with black ; pectoral and ventral fins of crys- talline transparency, excepting at their extremities, which arc faintly dotted with black. Irides silvery, pupil black." In a number of these Pollan from Lough Erne as well as Lough Neagh, the base of the last ray of the dorsal fin is exactly half way between the point of the nose and the ex- treme end of the longest upper caudal ray. Nine rows of scales from the base of the first ray of the dorsal fin to the lateral line, and the same number from the lateral line to the origin of the ventral fin, with eighty-eight scales forming the lateral line. The fin-rays in number on several specimens exactly as stated by Mr. Thompson. The vignette represents the bones of the cranium in the genus Coregonus.

This species of Motella, first described by Linnocus, is included b^' Dr. Parnell in his description of the Fishes of the Forth, a specimen, fourteen inches in length, having been brought to him by a Newhaven fisherman, who had caught it a little to the east of Inchheith on a Haddock lino baited with muscles. It is a species perfectly distinct from the Three or the Fivc-beardcd Rocklings, so much more common on various parts of the coast, and may at once be distinguished from cither by the greater length of the fila- ment, which is placed in advance of the almost obsolete first dorsal fin. This filament in a fish of nine inches long, measures one inch and seven-eighths ; and in another fish of ten inches and a half in length, measures two inches and a quarter, as I find from portions of two specimens so GADID^. sent me by Mr. Euing of Glasgow, to whom I am indebted for tlie opportunity of making known tlie new species of Smelt. These two specimens of the Four-bearded Rock- ling were taken near Rothsay, and in reference to them Mr. Euing's letters contain the following remarks: — "I have never met with the Three or the Five-bearded Rock- ling, but small specimens of that with four cirri are fre- quently brought in on the long lines from deep water. It is, indeed, by no means a very rare fish with us, and I have seen it at almost every visit to the coast since 1827, the year in which I first observed it." This fish is rare in the Baltic, but is not uncommon on the southern coast of Sweden ; it is found also among the islands of the Catigat ; on the west coast of Norway, and in the Atlantic. Dr. Parnell says, on dissecting the specimen, I found the stomach filled with shrimps and small crabs. The ctecal appendages were few in number; the roe was large; the ova small and numerous, and apparently in a fit state to be de- posited. It is probable that the habits of this fish are similar to those of the other species, but from its rarity it is diffi- cult to determine." Description by Dr. Parnell, from a specimen fourteen inches in length : " Form closely resembling that of the Five-bearded Rockling, but the length of the head somewhat greater compared to that of the body. The body elongated, rounded in front, compressed behind, tapering from the vent to the caudal extremity ; greatest depth less than the length of the head. Head one-sixth of the entire length, caudal fin included, slightly depressed ; snout blunt, projecting con- siderably beyond the under jaw ; eye large, of an oval form, placed high up, and about its own length from the point of the nose ; operculum rounded, oblique ; gill-opcinng large ; FOUR-BEARDED ROCKLINO. 31 gape wulc ; maxillary extending in a line with the posterior niaigin of the orbit ; teeth sharp and fine, forming two roAvs in the under jaw, and five rows in the upper ; a few are also placed in a cluster on the anterior part of the vomer; bar- bules four, one a little in front of each nostril, one at the extremity of the upper lip, and one on the chin ; tongue fleshy, smooth, and without teeth. Fins : — the first dorsal fin obsolete, scarcely discernible, commencing over the oper- culum, and terminating a little in front of the second dorsal, composed of a number of short, fine, capillary rays, of which the first is by far the largest ; second dorsal taking its origin in a line over the ends of the pectorals, and termi- nating a little in advance of the caudal ; anal fin commencing in a line under the twelfth ray of the second dorsal, and ending under the last ray but three of the same fin, in form similar to the second dorsal, but the rays scarcely more than one half the length ; the first ray simple, the rest branched ; caudal rounded at the extremity, the length of the middle rays equalling the space between the first and the twelfth rays of the anal, the lateral rays simple ; ventral fins jugular, the second rays the longest, about two-thirds the length of the pectorals ; the pectoral fins rounded at the extremities, equalling the length of the caudal ; the first rays stout and simple, the rest branched. The fin-rays in number are, — 1st D.50 : 2nd D. 50 : P. 16 : V. 5 : A. 43 : C 20, Vert. 52. Scales small, smooth, and adherent, covering the head, body, and membranes of the dorsal, caudal, and anal fins ; lateral line formed by a number of oval depressions, placed at intervals from each other, commencing over the oper- culum, taking a bend under the ninth, tenth, and eleventh rays of the second dorsal fin, from thence running straight to the middle ray of the caudal. Colours : — Back and sides of ox. GADIDE. a greyish brown ; belly dirty white ; second dorsal fin lighter in colour at the edge ; pectorals, caudal, and lower part of the dorsal, dark brown, approaching to black ; anal and ven- trals dusky."

Platessa elongala, The Long Flounder, Yaurell, Suppl. to Brit. Fishes. I AM indebted to Mr. Baker, of Bridgcwater, for several interesting communications on Birds and Fishes, one of the most vahiable of -which is the opportunity afforded me of making known what appeared to that gentleman to be a spe- cies of Flounder undescribed as a British Fish, and which, after having made the usual search, I have reason to believe is not only undescribed as a British Fish, but is altogether new to Ichthyology. I have only as yet seen the single specimen sent me for my use on this occasion by Mr. Baker, from which a drawing has been made of the natural size, and the reduced representation here given engraved on wood ; but I understand from IMr. Baker's son that his father had obtained a second example of the same fish. The specimen now before me was obtained at Stoford, in Bridgcwater Bay, in the month of December. Little is of course known of the habits of so recent and so rare an acquisition. VOL. II. D 34 PLEURONECTID.E. The whole length of this specimen is seven inches and three-quarters; the length of the head one inch and one quarter, and compared to the whole length of the fish, as one to six ; the greatest breadth of the body, dorsal and anal fins included, is one inch and three-quarters, and compared to the whole length of the fish, as one to four and a half ; the breadth, including the dorsal and anal fin, is to the whole length as three to eight. The body very thin, and very much elongated in form ; the lateral line passing straight from the tail along the middle of the fish till it approaches the operculum, then rises in a slight curve over the base of the pectoral fin. The scales on the body are of medium size, oval, with numerous radiating strise on the free portion. The fins deep, and the tail long. The outline of the whole head is rather circular, the mouth oblique from below upwards, and below the line of the lon- gitudinal axis of the body ; the jaws nearly equal in length, each furnished with a single row of small and regular teeth ; the eyes rather large, the upper eye, or that on the left side, being a little in advance of the lower, or that on the right side ; the inter-orbital bony ridge prominent ; the boundary lines of the preoperculum and operculum forming two con- centric portions of circles. The pectoral fin, arising imme- diately behind the edge of the operculum, is about half as long as the head ; the ventral fin, in a line under the edge of the operculum, is about half as long as the pectoral fin. The dorsal fin, commencing with short rays in a line over the eye, is at its greatest elevation about the middle of the fish, and from thence diminishes gradually to the end, which is on the fleshy portion of the tail, and short of the origin of the caudal rays ; the anal fin begins close to the ventral fin, immediately behind , the post anal spine ; the first and last rays short, those in the middle of the fin the longest, and the fin ends on the same plane as the dorsal. The tail is elongated; its LONG FLOUNDER. 35 length equal to that of the hcatl, ami in form but slightly rounded at the end ; the sides parallel. The fin-rays in number arc, — D. no : P. 11 : V. 6 : A. 96 : C. 24. The colour of this specimen on the upper surfiice is a uni- form pale brown, the membranes of the different fins being rather lighter in colour than the body of the fish ; the under surface of the body very pale wood-brown ; the iridcs yellow. This specimen has been preserved dry. The vignette below represents the cranium of the Common Flounder. I) 2 36 PLEURONECTID-E. SUBBliACHIAL MALACOPTERYGIl.

At the time of -writing the description of the Variegated Sole (British Fishes, vol. ii. page ^62), I had not seen a specimen of the true Solea parva sive lingiila of Rondeletius, and now find that I have included two distinct species in the synonymcs employed to designate the Variegated Sole. Tlic Rev. L. Jenyns, in his Manual of British Vertebrate Ani- mals, appears to have suspected that there was a fourth spe- cies of Sole on our coast, since, at the conclusion of the de- scription of his third species, he has observed, " further ob- servation is necessary in order to decide whether, in this instance, I have confounded two nearly allied species." In the published proceedings of the Royal Society of Edinburgh for January 1837, Dr. Parnell has figured and briefly described, under the name of Monochiriis minutus, a SOLENETTE. 37 small species of Sole obtained by liini at Brixliani on the Dcvoiiijhirc coast, Mliicli a])pcars to be the true Solca parca sive lingula of Kondclctius. This small fish is at once dis- tinguished from the Variegated Sole of Donovan, and other Englisli autlutrs, by the tapering of the body towards the tail, and more particularly by the dorsal and caudal fins being united to the base of the tail, which is not the case in the Variegated Sole. This union of the two fins with the tail is shown in the figure given by Rondeletius, and again by AVilloughby, as referred to. Dr. Parnell has obtained several examples of this interest- ing little species, which is nut unfrequently taken in the trawl-nets by the fishermen of Brixham, but on account of its diminutive size it is seldom brought on shore. It has evidently been confounded with the Variegated Sole ; but, independently of other distinctions, the Variegated Sole has the tail separated from the dorsal and caudal fins by a consi- derable interval. The Variegated Sole of Donovan and of Montagu's MS. the Red-backed Flounder of Pennant's Zoology, and the Variegated Sole of Dr. Fleming, are so many specimens of the truly Variegated Sole, and are each of them quite dis- tinct from the true litigitla. Duhamel appears to have dis- tinguished and figured both species. Mr. Thompson has obtained both species on the coast of the North of Ireland, and by his kindness I have now his specimens before me for comparative examination. Dr. Parnell has given me two examples of his Monochirus im'tiutus, which, as before ob- served, I believe to be the true Su/ca parva sivc lingu/a of Rondeletius ; and I have also two specimens of the true Variegated Sole ; one of these, from which the figure in the British Fishes was drawn, has the dark clouded variation in colour extending, as in Donovan's figure, over the back as well as the tins: in a specimen belonging to Mr. Thompson, 38 PI.EURONECTID^'E. in one of my own, and in Montagu's specimen, as described in his MS. the dark variations in colour are confined to patches on the fins, as in Pennant''s figure ; but without refer- ence to colour, this species is immediately known by the space which occurs between the tAvo elongated fins and the tail, which Montagu says was equal to half an inch in his specimen, which measured nine inches. Both these species belong to the genus Monochirus of Cuvier, distinguished from those of the genus Solea by the very small size of the upper pectoral fin, and the very rudi- mentary state of the pectoral fin on the under side, and is, indeed, sometimes entirely wanting. Of our two British species of Monochirus, the M. lingiiatulus of Cuvier has the smaller upper pectoral fin of the two, as observed by Mr. Thompson, who has, in a recent number of the Annals of Natural History, published some interesting details on the two British species of the genus Monochirus. From the numbers of these fishes which are taken in the trawl-nets off Brixham throughout the whole year, says Dr. Parnell, and from their never appearing to attain a large size, there can be little doubt but that they are arrived at their full growth. The fishermen, who appear perfectly familiar with their appearance, call them Red Soles ; and scarcely a trawl-boat leaves Brixham Harbour that does not capture a dozen or more of these fish daily ; but, from their diminutive size, they are either thrown overboard, or left to decay at the bottom of the vessels. Description : — " Length five inches ; the width at the upper third nearly two inches : the colour of the back light reddish brown, the under surface pale white ; every sixth or seventh ray of the dorsal and anal fin black. In shape this fish is similar to the Common Sole, but is of a more wedge- shaped form, becoming narrow at the caudal extremity. The head is small, one-sixth of the whole length ; the mouth SOLENETTE. 39 is crooked; each jaw is furnished witli a number of minute tcetli, placed close together, and extending but half way round the mouth ; the eyes are small ; the upper, or left eye, a little in advance. The dorsal fin commences immediately over the upper lip, and runs down the back, to be connected with the caudal rays ; the anal fin begins under the posterior margin of the operculum, and continues to the tail. The number of the fin-rays are, — D. 73 : P. 4 : V. 4 : A. 54 : C 14. The scales are small, with from twelve to fifteen denticles at their free extremity, rendering the whole surface of the fish rough to the touch when the finger is passed along from the tail to the head. The pectoral fin, on the eye-side, is small, with the lower half black, while the fin on the opposite side is very minute, and of a pale Avhite ; the lateral line is straight throughout ; the tail is rounded at the end, and mottled with brown."

Drummond on the beach at Carnclough, near Glenarm in the county of Antrim, in the month of June 1836, and from its appearance when found it was conjectured that it had been cast ashore by the tide of the preceding night, when a strong easterly wind prevailed. The specimen was given by Dr. Drummond to his friend Mr. W. Thomp- son of Belfast, and being new in form, was made by the latter gentleman the subject of a communication to the Zoological Society, which appeared in the Proceedings and Transactions of that Society as here quoted. DRUMMOND*'s ECHIODON. 41 This specimen, Mr. Thompson observes, " being, so far as known to me, unique, I have been unwilling to injure its appearance by dissection. In external characters it is ex- chuled from the ophidia proper in consequence of not having the barbules ; and though agreeing with the FicrasJ'crs in the negative character of wanting these appendages, yet, by having the dorsal fin strongly developed and elevated, it ranges not with them." " Its want of the very ol)vious character of the Ophidia, renders all comparison with them unnecessary ; but of two species belonging to the Fierasfers, and which approach the present specimen most nearly, I may state that it })ossesses many of the characters of the Ophidinm ficrasfer of Risso, but differs from that species in the teeth, (botli jaws arc de- scribed as armed with three rows of sharp and hooked teeth,) number of fin-rays, and some minor characters'; besides, there is nothing said of the remarkable teeth terminating both jaws, as exhibited in my specimen. In the Regne Animal we again find an Ophidium doitatinn described as having in each jaw " deux dents en crochets,'^ but no further details are given. In this only character, however, the Ophidism dcntatum dif- fers from my fish, which has four large hooked teeth in the upper and two in tlie under jaw." " Although when this fish first came into my possession, I saw that it might be classed under the Malacopteri/gii jipodes, and be placed near Ophidium, I considered that in a natural arrangement it would best constitute a new genus of the flimily Tanioidca (Riband-shaped). In being apodal it was not excluded from this family, as two genera belonging to it are destitute of ventral fins. I did not hesitate to place it under the Acanthopteri/gii, as some genera wliich are in- cluded in this order are, like it, strictly Malacopterygian, their natural connexion with genera having fins with spinous rays being considered — and in my opinion most philoso- 42 MURiENID.E. phically — to outweigh this character ; and further, I felt less reluctance in thus placing it, in consequence of Cepola rubes-' cens, which it assimilates in some respects, having but one spinous ray, and that in the ventral fin. At the suggestion of John Edward Gray, Esq. F.R.S. I have, however, recon- sidered the subject, and have come to the conclusion here advanced." As a diiFerence of opinion may still exist with regard to the position of this genus, I think it due to Mr. Thompson to subjoin the observations originally made. *' Like certain other genera which arc comprehended under Acanthopterygii, the first order of the osseous fishes, its fins are altogether destitute of spinous rays ; but, like those alluded to, such as Zoarcus, &c. its other characters seem to point out the Tcenioides as the family to which it belongs. Of the eight genera of Tanioides already known, viz. Lepi- dojms, Trichurus, Gymnetrus^ Stylephorus^ Cepola, Lopho- tes, Trachypterus, and Alepisaurus, the specimen under consideration agrees with Trichiurus and S'tj/lephoriis in being apodal, or wanting ventral fins, but in this character only is there any generic accordance. Though considerably more elongated, from the head posteriorly it approaches most nearly to Cepola 7^2ibesce?is in the form of the body, and in the forward commencement of the anal fin, which, with the dorsal, is prolonged until it joins the caudal ; but it is only in the continuity of these fins until this junction is effected that the resemblance holds, as in my specimen, the dorsal rays, the five foremost of which arc very short, increase in length posteriorly, and near the caudal fin are about three times as long as the depth of the body beneath them ; in the anal fin, which is throughout much deeper than the dor- sal, the rays likewise increase posteriorly ; and near the caudal are in length four times greater than the depth of the body at the same place. The length of the posterior rays of these DRUIVIiM()Nl)''s ECHIODON. 43 fins causes the dorsal, anal, and caudal, to appear as one ; whilst, though they do join in Cepola rubescens, the last ray of the dorsal and anal being much shorter than the outer rays of the cauilal, may at tlic same tinie be said to mark distinctly the termination of each fin. In my specimen the anal fin origi- nates two lines in advance of the dorsal fin." In the form of the head, and in dentition, it differs so re- markably from all the other genera as to render a comparison with them unnecessary. Its absolute characters must suffice for distinction. Description. — " Total length eleven inches ; greatest depth at one inch four lines from the snout, six lines, thence pos- teriorly gradually narrowing ; greatest breadth of body an- teriorly three lines ; at the middle of the entire length one line, and thence to the tail becoming gradually more com- pressed. Head one inch two lines long, or rather more than one-ninth of the entire length ; profile sloping forward equally on both sides to the snout, which is truncated, and projects one line beyond the lower jaw ; narrow, increasing in breadth very gradually from the snout, its breadth compared to its length as one to three and a half; height half its length, com- pressed at the sides, and rather flat above from the eyes back- ward ; from the eyes forward a central bony ridge ; snout viewed from above somewhat bifid, in consequence of the for- ward position of the large teeth on each side. A few large punctures extend from the snout below the eye, and are con- tinued just behind it ; a series of small ones closely arranged extend from the upper portion of the eye in a curved form posteriorly to near the edge of the preopercle, and thence a dou])le row extends downwards. Nostrils very large, placed just in advance of, and before the centre of, the eye, and in form a somewhat oval transverse aperture. Eye large, occu- pying the entire half of the depth of the head ; its width greater than its height ; in the length of the head occupying 44 3IUR.ENID.E. the place of one in four and a half; its distance from the snout three lines, or equal to its diameter, consequently two and a half of its diameters are contained between it and the edge of the operculum. Operculum rounded at the base, terminating in a minute point directed backwards, strongly radiated, strise distant ; preoperculum ascending vertically ; cheeks smooth and soft. Mouth rather obliquely cleft. Teeth, two large strong ones, placed close together, and curving inwards at each side the extremity of the upper jaw, the two inner one-sixteenth of an inch apart. In the lower jaw one slender rounded tooth, nearly one line long on each side, curving outwards at the base, and inwards at the point. Entire upper and under jaw and vomer densely studded with small bluntish teeth, somewhat uniform in size ; vomer ex- tending far forward, and very much developed, forming a cavity in the lower jaw, and in advance of the tongue when the mouth is closed ; a series of rows of teeth similar to those last described on the palatal bones : all the teeth of the upper jaw exposed to view Avhen the mouth is closed. Tongue short, not reaching within two lines and a half of the ex- tremity of the lower jaw, and apparently toothless. On the dorsal ridge, one inch from the snout, or two lines and a half behind the cranium, is a short, stout, bony spine, not very conspicuous, and, excepting at its extreme point, covered with skin : it is six lines in advance of the first ray of the dor- sal fin. Scales none, but it may have been divested of them during its short exposure on the beach. Lateral line incon- spicuous, being a slight depression extending in a straight line along the middle of the sides posteriorly, or throughout the greater portion of its length, but anteriorly nearer to the dorsal than the ventral profile.

On the 30th of the same month I was favoured with a letter from Dr. H. S. Boase, of Penzance, containing an account of the capture of a Spinous Shark on the 23rd of that month, near the Land's End ; and Dr. Boase also very kindly sent me in his letter pen-and-ink sketches of two views of this Shark, made to a scale of one inch to a foot, with representations and specimens of the teeth and spines. In November 1837, the Rev. Robert Holdsworth sent me notice by letter of the capture of a Spinous Shark, taken in a trawl-net off Brixham, with pen-and-ink sketches of the form of the body, with a small portion of its spine-studded skin, and some of its teeth. At the meeting of the British Association at Newcastle- upon-Tyne, in August 1838, Arthur Strickland, Esq. of Bridlington, exhibited in the section devoted to Natural History a drawing, and read a short description, of a Spinous Shark, which had been recently found on the Yorkshire coast, and was evidently of this species, Mr. Gray referring to the figure of it lately published by Dr. Andrew Smith in the first number of his " Illustrations of the Zoology of South Africa,'" which the drawing exliibited ]»y Mr. Strick- land very closely resembled. Lastly, I may add that on the 9th of November 1838, the Rev. Robert Holdsworth sent me word that another speci- men of the Spinous Sharh had been caught on a fi.sherman"'s line off Berry Head on the previous Tuesday. I soon af- terwards received a notice of this last capture from my SQUALID/E. friend Mr. Couch, of Polperro, and also from Mr. Heggerty, of Torquay, to which place, as I understood, this last speci- men had been brought for preservation. Four examples of this Shark are therefore known to have been obtained on our coasts within the last three years, and one in the summer of 1830. This very remarkable Shark was first describea by Brous- sonnet under the name of Le chien de mer bmicle, in the " Memoires de TAcademic des Sciences pour 1780,'"' and, as may be seen by the numerous synonymes at the head of this subject, is a species that is exceedingly well known, having a wide geographical range, extending from the North Sea to the Cape of Good Hope in one direction, and from the Shores of Italy into the Atlantic in another. The specimen described by Broussonnet measured only about four feet in length ; but it has been taken upwards of seven feet long on the Cornish coast; and M. Risso mentions that one of four hundred pounds*' weight, and therefore pro- bably still longer than the Cornish specimen, was caught by the Mandrague, or Tonnaro fishermen of Nice, in the hori- zontal nets 'set up by them to catch Tunnies. Some differences will be observed in the comparative length and thickness of the figures here given, the first of SPINOUS SHAUK. 57 wliicli is tiikon from tin- drawinL;- sent me by Mr. Jolin IIcv of the Filey liav s})eeiinen ; the second representing, on tlic other siilc, a more bulky fish, is taken from Dr. A. Smith"'s illustrations. The figures given by Lacepede and the Prince of Musignano are rather long and slender, and were ])robablv taken from specimens of small coniparative size ; the figure sent me by Dr. Boase from a fish more than seven feet long, and the drawing exhibited by ISIr. Strickland at Newcastle, more resembled the figure by Dr. Smith. Some specimens arc described as being intermediate, and all these differences in the same species may be referred to age or sex, or both, a young male and an old female presenting the greatest con- trast. The decided similarity in the teeth, which arc very ])eculiar, and which only differ in size, with the particular character of the skin and its spines, with their radiated bases, leave no room to doubt that these various examples belong to one and the same species. We become a little acquainted with some of the habits of this Shark by noticing the circumstances under which it has been captured. Of the first Cornish specimen. Dr. Boase says, this Shark Avas caught on the 23rd of July, 1836, west of the Long Slips, Land's End. Just before the moon set the fishermen had been very successful, but all at once lost their sport, or as they expressed it, " the Congers suddenly sheered off to a man." When hooked, it was not more troublesome than a Conger ; but when brought to the water's edge, it gave battle, and was secured with great difficulty. The first specimen noticed by the Rev. Robert Holdsworth as canglit in a trawl-net off Jirixham, had a portion of a Gurnard in its stomach. Of the third specimen, caught on the southern coast, near Berry Head, Mr. Holdsworth says, this Shark was taken near the bottom on a hook baited with cuttle. 'I'lie nun were fishing for Conger Eel, and other large fish, when this Shark was liooked. They describe his 58 SQUALID.E. action in the water as most powerful, and were obliged to let him run with the line four times to the bottom before they could hamper him Avith a sliding noose let down over the line to his tail. These lines and the trawl-net only do their work at the bottom, and we may, therefore, conclude that this species is a Ground Shark. As such Cuvier had arranged it in his genus Sci/mnus, and Dr. Andrew Smith, who from his extensive acquaintance with this division of the cartilaginous fishes is an admitted authority, confirms this opinion. Of this Spinous Shark, Dr. Smith says, " This species is comparatively rare at the Cape of Good Hope. It is described by the fishermen as sluggish and unwieldy in its movements, and but seldom to be observed towards the sur- face of the water. When they obtain specimens, it is gene- rally at a time when they are fishing in deep water, and when the bait with which the hooks are armed is near to the bot- tom. In this respect it resembles the Scyllia, or Ground Sharks ; and, if we were to regard only its internal organisa- tion, we should be disposed to consider it as closely allied to that genus." Never having seen a specimen of this Shark, the following description of its colour and form is derived from Dr. Smith''s work. Colour : — The head and back, as far as the first dorsal fin, dark leaden grey ; the rest of the back, the sides, and the belly, pale coppery yellow, clouded with purple and brownish tints ; and the belly besides is marked with blotches of light vermilion red ; the fins towards their bases reddish brown, tinged with dull grey, toAvards their extremities a lighter shade of the same colour ; chin, sides of muzzle, and some- times a spot behind the eye, dull white ; eyes coppery green. Form, &c. — Body very thick in proportion to its length, with only a slight diminution in size towards the tail ; the back in front of the first dorsal fin nearly straight ; the head SPINOUS SHARK. 59 flat above, ami sliglitly slopiug to tlic muzzle, wliicli is rounded ; nostrils transverse, and each partially divided by a narrow membranous lobule, which projects backwards from its anterior margin ; their position is nearly over the most pro- jecting, or central portion of the upper jaw, considerably nearer to the eyes than the tip of the snout, and about half way between the latter, and the angle of the mouth. Eyes rather nearer to a line raised from the angle of the mouth than to the nostrils ; pupil circular and small ; postocular spiracle scarcely visible. Gape wide and arched, having at each corner a triangular fold of shin formed by the union of the upper and lower lips. Teeth regularly placed upon each jaw, only one row in use at a time, the rest reclined ; they are large, compressed, and somewhat quadrangular, the cut- ting edges nearly horizontal, and both of their sides arc generally bicuspidate, as will be seen by the figures here in- serted, representing from both specimens the teeth of both jaws as opposed to each other. ii' ' ^jM S^Tl!^^^^^ g% ^'■■'. ;: ^^S ^^j^^^jM^^ Branchial openings all in front of pectoral fins ; the first not more than half the length of the fifth. Pectoral fins rather small, the hinder edges nearly square ; the dorsal fins arc small, the first narrower at its base than at its extremity, which is slightly rounded ; the second nearly throughout of equal breadth, the hinder edge almost square ; the ventral fins short, Vjroadn- behind than at their bases, and their pos- terior edges slightlv undulated ; the caudal fin ei\tire, some- 60 SQUALID.E. what triangular, and slightly falciform ; the upper portion high above the line of the back, the lower scarcely below the line of the botly immediately in front of it. Lateral line distinct, commencing above the branchial openings, and ex- tending nearly without curve or undulation to the commence- ment of the caudal fin, from thence it ascends the latter, and extends along it, nearer to its anterior than posterior edge, until it reaches its upper extremity ; at its origin this line is nearer to the middle of the back tlian the base of the pectoral fin ; to tlic touch it feels slightly rough, which arises from its being beset with a number of minute prickles, which are most distinctly seen in preserved specimens. The surface of the skin both on the body and fins is more or less sprinkled with strong bony-looking spines, with large circular and flat- tened bases, which are striated from the centre towards the circumference. These spines vary in size as wxll as form, some being hooked, others quite straight ; in some places they are disposed in clusters, in others they are solitary, and on the extremity of the muzzle are nearly wanting. The appendages to the ventral fins in the male seldom extend much beyond their posterior margins." According to M. Risso, the females of this species have a smaller number of these spines than the males. J ..« ^^ HVnniER-HKADRD SMAHK. (11 CIIOKDROPTERYGU. squalida:. !)j): THE HAMMER-HEADED SHARK.

In the sketch of the Natural History of Yarmouth and its Vicinity, by C. J. and James Paget, which I have fre- quently had the pleasure to refer to in the History of the British Birds, and also in the British Fishes, it is stated at page 17 that a specimen of the Squalus zygosna^ or Ham- mer-headed Shark, was taken there in October 1829, and deposited in the Norwich Museum ; and by the kindness and influence of J. H. Gurney, Esq. of Norwich, I have had the loan of drawings that were made from this Shark sent to London for my use in this work. Among the numerous species included in the genus Squalus of Linnreus, — and I might say, indeed, in the whole class of Fishes, — there is no form more extraordinary than that of the Hammer-headed Sharks, four species of which are noticed in the memoir by M. Valenciennes here quoted, where they arc considered as a sub-genus, under the name of Zygcena. The Hamm.er-headed Shark taken on the coast of Norfolk, being also a native of the Mediterranean Sea, has been long known, and is figured in the works of Belon, Rondelet, and Salvianus, as already quoted. Its greatest singularity con- sists in the extraordinary form of the head ; but its habits, as for as they are known, afford no physiological illustration of this very remarkable structure. In other respects it is very like the Sharks in general. This species is said to be ferocious, to frequent deep water, and measures from seven to eight feet in length. Baron Cuvier states that it has been known to attain the length of twelve feet. The female produces ten or twelve young ones in spring, which acquire considerable size by the end of autumn. In some countries the flesh of several species of Sharks is eaten, but that of the Hammer-headed Shark is said to be not only hard, but very unpleasant both in smell and flavour. HAMMER-HEADED SHAHK. C3 Tlio ln-;i(l of tliis Sliark, — roprcscntatioii.s of the upper and under surfuee of wliieli, on a small scale, arc given below, — measured from one eye to the other, is very large and Avidc ; the eyes are furnished with eye-lids, whifh arise from the internal part of the orbits, the iridcs arc golden yellow, the pupils black ; the nostrils are elongated, and open immediately underneath the depression, or notch, in the anterior margin of the laterally expanded portions of the head ; the mouth semicircular, and furnished with three, four, or five rows of teeth, depending upon the age of the specimen ; these teeth are large, sharp, somewhat triangular and curved, with smooth cutting edges when the Shark is young, but serrated afterwards ; the teeth in the upper jaw having their points directed towards the angle of the mouth ; those of the lower jaw have the same direction, but they arc narrower. ly The body is elongated, covered with a skin slightly gra- nulated ; the colour greyish brown above, nearly white be- neath : branchial openings five, all before the base of the 64 SQUALIDE. pectoral fin ; the pectoral fins nearly triangular ; the first dorsal fin large; the second small, and placed just in advance of the commencement of the tail ; the inferior lobe of the tail small, the superior portion as long as the head of the fish is wide ; the anal fin is under the second dorsal. This species is found in the Mediterranean, on the shores of the various countries of Europe, in the Ocean, and on the coast of Brazil. To make this subject as complete as my means will allow, and afford an opportunity of identifying any other species of Zi/gasna that might wander to our shores, I here add, as a vignette, representations of the heads of the other known species, of which No. 1 is Zi/gceiia tudes, Val. the synonymes being, according to M.

HAMMEn-HK ADKn SHARK. 65 In shape tlie fins arc like tliosi> of tlic lour species already known ; the only difference I have observed, says Dr. Can- tor, is the situation of the anal fin, which in the present spe- cies is somewhat anterior to the second dorsal, while these fins in the others are opposite. ^tv A \ \yl\J vol,.

" This fish," says Dr. Parnel], " wliicli was obtained in the Frith of Forth in the month of May, seems to be a new species of Skate, since I am not aware of its having been previously described. It appears to be the connecting link between 'J?a/a batis and Jiaia oxj/rhj/7ichus^ to both of which it is closely allied, and it is from this circumstance that I suggest the specific name of intermedia.'''' FLAPPER SKATE. 67 " It is distinguished from Rata ball's, in the upper sur- face of tlie body being perfectly sniootli, witliout granulations, and of a dark olive colour spotted with wliitc ; in the ante- rior part of each orbit being furnished with a strong spine pointing backwards ; in the dorsal fins being more remote from each other, and in the anterior margins of the pectorals being rather more concave, giving the snout a sharper appear- ance ; whereas, in Ram batis, the upper surface of the body is rough to the touch, of a uniform dusky grey without spots; the orl)its without spines ; the dorsal fins nearly approximate, and the anterior margins of the pectorals nearly straight." " It is likewise removed from Rata, oxyrhi/nchtcs^ in the snout being conic ; the under surface of the body dark grey ; a spine in front of each orbit, and the back of a dark olive- green, spotted with white ; whereas in the Raia oxj/rfnjn- c/ius, the snout is sharp and long, with the lateral margins parallel near the tip ; the under surface of the body pure Avhite, and the back of a plain brown without spots." This, species is not uncommon in the Frith of Forth, and I have met, observes Dr. Parnell, " with two examples of a variety of this fish which were taken in the salmon-nets at Queensferry. They were both of small size, about eighteen inches in lenffth. The back was of a uniform dark olive green without spots of any description, covered with a thick mucus ; under surface of a dark grey ; body very thin ; snout sharp, conical ; pectorals at their anterior margin rather sinuous, passing off somewhat suddenly at that part, in a line with the temporal orifices, giving the outline of the anterior part quite a different appearance to that observed in Raia intermedia ; the anterior part of each orbit is furnished with a spine ; back perfectly smooth ; tail with one row of spines on the dorsal ridge ; fins, and in all other respects, similar to Raia inlcrmedia.'''' A female specimen of this fish, about two feet in length, 68 BAllD/E. tail included, is thus described by Dr. Parnell : — " Body rliomboidal, the transverse diameter equalling the distance between the point of the snout and the last tubercle but three on the central ridge of the tail ; from the point of the snout to the temporal orifice, rather more than one third the length as far as the end of the anal fin, and one fourth the length as far as the termination of the first dorsal. Body very thin ; snout pointed, conical ; pectorals large, somewhat of a triangular form, uniting in front at the snout, and ter- minating at the base of the ventrals ; the anterior margin rather concave, the posterior margin rounded ; ventrals about three times the length of their breadth ; anals commencing close behind the ventrals, and terminating in a free point; rounded at the outer margins. Tail sliort and firm, being no longer than the distance from the base of the anal fin to the anterior margin of the orbit ; along the mesial line is a line of tubercles with sliarp points directed downwards, about eighteen in number, commencing at the base of the anal, and terminating at the commence- ment of the first dorsal fin ; no lateral spines visible. First dorsal fin small, rounded at the free extremity ; situated about one third of the length of the tail from the tip: the base of the fin about equalling the length : second dorsal rather smaller than the first, and about the same form, placed about half-way between the termination of the first and the tip of the tail ; caudal fin rudimentary. Colour of the upper surface of the body of a dark olive green, with numerous white spots ; on the under surface dark grey, with minute specks of a deeper colour. Eyes rather small, flattened above, placed in front of the temporal orifices ; skin both above and below perfectly smooth ; a strong, sharp, bent spine in' front of each orbit ; no spine or tubercles of any description on the back. Mouth large, placed beneath ; teeth small, not so large or so sharp as those in Rata balia. SANDY RAY. CIIOXDROl'TERYGll. 69 UAllUJE. THE SANDY RAY. Rata radula, Delau. Mem. I'oiss.

In the bccund vohiine of the New Serie.s of the Magazine of Natural History, and the eleventh volume of the whole 70 RAIID.E. work, Mr. Couch lias given .a figure and description of a species of Ray, wliicli lie hopes will be sufficient to prove that it cannot be confounded with any other Ray recognised as British ; " but whether," says Mr. Couch, "it can be re- ferred to any species described by other authors, I am not able to specify, except that I have with some degree of hesitation, supposed it to be possibly the Raia asten'as of Ray, Syn. Pise. p. 27." " I cannot, however, persuade myself but that this species has been described by some authors, to whose writings I have no opportunity of obtaining access ; I therefore refrain from assigning to it a trivial name, that I may be in no danger of adding to science a useless synonyme. Its English name of Sandy Ray, will be sufficient as a provisional de- signation." The close accordance of the figure and description of this fish given by Mr. Couch, to the figure and descriptions of the Raia radula of the authors here quoted, leaves little room to doubt but that they refer to the same species, and I include the fish, therefore, as here given, on Mr. Couch's authority. " It bears but a distant resemblance to the Raia maculala^ or Homelyn," Mr. Couch observes, " either in appearance or value ; for while the Homelyn is esteemed as food, either fresh or salted, this is thought worthy only to bait the crab- pot, or, just as frequently, to be thrown aside for manure. It is of frequent occurrence in moderately deep water, from spring to the end of autumn. In winter, however, it is not often seen, chiefly, perhaps, because at that season the boats do not venture quite so far from land ; but, perhaps, also, from the fish having changed its quarters. It seems to be an indiscriminate feeder, living on small fishes, and different kinds of Crustacea." " The specimen described, which was of the ordinary size.

From the snout the ridge is elevated to the eyes, a distance of live inches and three-quarters ; eyes two inches asunder ; temporal orifices large. Body thickest pos- teriorly; the tail stout at its origin, rounded above, tapering; a groove along the body and tail ; two fins on the latter close together. A few spines near the end of the snout ; a semicircle of them behind each eye ; four short parallel rows on the centre of the back, and a middle one continued along the groove to the tail, which is covered with stout hooks, scarcely in regular order. The remainder of the body smooth. Colour above a uniform dusky brown, white below. On the back a variable number of ocellatcd sjiots, the size of the section of a large pea ; the centre pale yellow, the margin a deeper impression, of the colour of the skin. I have counted from eight to sixteen of these spots in different specimens, and believe they have no determinate number; but they are always placed, on each side, with corresponding regularity.'" " Besides this description and figure, which I hope will enable those who visit our fishing vessels to ascertain this species, I will further observe, as marks of distinction from the other British species of this genus, that in addition to the form of the teeth, which are crooked and slender, resem- blin? a bird''s claw in miniature, but ^\ liich still are less long, slender, sharp, or crooked, than in young specimens of the Raia oxi/rhi/nchi/s, it may be distinguished l)y a great ten- 72 RAIID.E. dency to circularity in the disk, formed chiefly by a rounding off of the pectoral fins, by a flatness of the anterior portion, by the uniformity of its colour, the regularity of the spots, and the comparatively short and tapering tail.""

A GENERAL OUTLINE OF THE ANIMAL KINGDOM, AND MANUAL OF COMPARATIVE ANATOMY. BY THOMAS RYMER JONES, F.Z.S. PROFESSOR OF COMPARATIVE ANATOMY, IN KING'S COLLEGE, LONDON. This work is intended to comprise a general view of the Animal Creation, exhibiting the sti-ucture and internal economy of every class of living beings, and their adaptation to the circumstances in which they are severally destined to exist. Six parts, at 2s. 6d. each, containing 129 illustrations, are now published — the work will be completed in fifteen ; the whole will then form a manvial of comparative anatomy and animal physiology, equally adapted to the man of letters, the zoologist, or the anatomical student. In order to render the work as intelligible as possible to unscientific readers, a glossary of technical and scientific terms will be given in the concluding part. About three hundred illustrations will be embodied in illustration of the text. To accommodate the possessors of the large paper copies of the other works on Natural History issued by the same Publisher, a few copies of this work will be printed to correspond. A HISTORY OF BRITISH QUADRUPEDS, INCLUDING THE CETACEA. BY THOMAS BELL, F.R.S., F.L.S., V.P.Z.S. PROFESSOR OF ZOOLOGY IN KING'S COLLEGE, LONDON. The letter-press of this volume contains an account of their habits, utility in food, manufactures, agriculture, or domestic economy, and the noxious qualities of such as are in any way injurious to man ; and an attempt has been made to define the characters of many of the species with more accuracy than had been done by previous authors. The illustrations comprise a figure of every species, and of many varieties, with numerous pictorial tail-pieces and anatomical diagrams, illustrative of the text, amounting, in all, to 200. Price of the work, in demy 8vo. 28*. A few copies are also printed in royal Svo, price 21. 16s., and a very limited number in imperial 8vo, price 41. 4s.

BY THOMAS DKLL, F.R.S., F.L.S., V.P.Z.S. PROFESSDR OF ZOOLOliV IN KIN(i's COI.LEdE, LONDON. The Reptiles of this country, although few in number, are not devoid of considerable interest ; their habits are popularly much misunderstood, and several innocent and useful species are shunned and destroyed, from a mistaken notion that they are directly or indirectly noxious to man. The elucidation of their habits, the distinctive description of the species, their g-eographical distribution, and the history of the trans- formation of all the amphibious forms, are amongst the subjects discussed. In addition to a figiu'e of each species, and of some of the most im- portant varieties, the Illustrations comprise many of structure, develope- ment, and transformation. In one volume 8vo, of 166 pages, and containing above 40 illustra- tions, price 8s. 6d. demy 8vo, 17*. royal 8vo, or 1/. 5s. (id. imperial 8vo. A HISTORY OF BRITISH BIRDS, BY WILLIAM YARRELL, F.L.S., V.P.Z.S. The first volume is now before the public ; and, so far as the work has proceeded, the publisher refers to it with pleasure, as a fulfilment of the promises made in the original prospectus. This volume of the History contains descriptions of 105 species, their synonymes, generic and specific characters, geographical range, habits, food, nidification, sometimes with nests, eggs, and other interesting particulars. The illustrations include one representation of each species, and frequently, of male and female : the distinctive diff"erence between the young and adult bird is sometimes given in a third figure, and, occasionally, the variation from summer to winter plumage is shown. Other illus- trations, comprising modes of capture, anatomical distinctions, or the most interesting features of internal or external structure, are introduced the more fully to illustrate the descriptions. Price of the volume 28.9. demy 8vo, or in parts, published each alternate month, 2*. 6d. A limited number is also printed on royal 8vo, price 5*. each part, and fifty only on imperial 8vo.
