Description

{Form). Head depressed and very broad: eyes large: mouth very wide, with irregular rows of incurvated teeth; in the roof of the mouth likewise a congeries of teeth: no tongue, a broad abrupt rudiment only supplying the defect: body compressed, but remarkably so as it approaches the tail: above the pectoral fins, on each side, a row of tubercles, nine or ten in number, from the last of which commences the lateral line, which descends in a curved direction at the middle, and from thence continues straight to the tail: first dorsal placed in a furrow, rudimentary, consisting of three slender feeble rays easily overlooked: second dorsal reaching almost to the tail, with sixty-two rays: anal corresponding, with fifty-nine: caudal rounded, with thirty-six: pectorals also rounded, with twenty-three: ventrals with six rays, the last three of which are very slender and short, and the whole connected by a very delicate membrane.

* According to Nilsson, it is the third ray which is so much elongated beyond the others, †According to Mr. Couch, " a few spines are placed before the anal fin." ‡ Wern. Mem. vol. vi. p. 569.

{Colour). Deep brown, the folding of the lips excepted, which are snow-white: irides yellowish. Davies.

Pennant's description of this species was taken from a specimen sent him from Beaumaris by Mr. Hugh Davies, which gentleman has given some additional particulars respecting it in the last edition of the " British Zoology." Within these last three or four years, it has been obtained from Berwick Bay by Dr. Johnston *, a circumstance conclusive as to the existence of the species †, though it is still but little known to many of our naturalists.

There is great reason for believing that this supposed species, obtained by Mr. Jago from the coast of Cornwall, where it has been since found by Mr. Couch, is identical with the .R. trifurcatus last described. Jago says but little of his fish by which it can be recognized. He has, however, annexed a figure, which, allowing for the rude style in which drawings were executed in those days, might easily be intended for the species just mentioned. The following is Mr. Couch's description of his own specimen. "Length ten inches: head wide and flat: eyes forward and prominent: under jaw shortest: teeth in the jaws and palate, sharp and incurved, and some in the throat: a small barb at the under jaw: body compressed, smooth: first dorsal fin triangular and extremely small; second dorsal fin and the anal fin long, ending in a point: tail round: ventral fins with several rays, of which the two outermost are much elongated, the longest measuring two inches: the fins all covered with the common skin: a furrow passing above the eyes to the back. Stomach firm, with longitudinal folds: no appendix to the intestines: air-bladder large, and of unusual form. In the intestines were the remains of an Echinus".
