Having, through the kindness of Mr. Gray, had an op- 

 portunity of inspecting a collection of Falkland Island 

 fish, I am enabled to give a fuller account of the species of 

 Notothenia than I could from Sir James Ross's specimens. 

 The figures of N. cornucola, in the former fasciculus, having 

 been taken from worn and mutilated examples, and the 

 ventral fins having, through inadvertence, been altogether 

 omitted (in Plate VIIL, fig. 4 and 5), the defect is sup- 

 plied by more correct representations. 



The specimens, which are preserved in spirits, have the 

 back, sides and head of a clear umber, or chestnut-brown 

 colour, varied by a paler yellowish-brown, in a clouded or 

 banded pattern. An oblique pale stripe crosses the fore 

 part of the cheek, and is defined above and below by dark 

 umber brown blotches ; the base of the pectoral is crossed 

 by a dark bar, and the hinder part of the first dorsal is 

 black, as in most other species. The space between the 

 ventrals is more scaly than appeared from the injured spe- 

 cimens, but the scales over the whole of that region are 

 small, and deeply imbedded in the mucous skin. The 

 teeth are subulate, and rather long for the size of the indi- 

 vidual, as compared with some of the other species. They 

 form two or three rows in the front of the jaws, and merely 

 a single series on the sides. The vela are, as in the others, 

 large, and covered with tumid-lipped pores. Length, six 

 inches.

 Plate XL, figs. 5, 6, natural size. 

 This Notothenia resembles cornucola in its naked jjorous 

 head, the distribution of the scales on the upper border of 

 the operculum, in the cheek stripe, dark mark on the base 

 of the pectoral, and in the numbers of the rays of the ver- 

 tical fins. It has, however, a fuller bluff head, with large 

 lips, and is well distinguished from it and the other species, 

 by a broad, longitudinal, pale, spotless stripe on the side, 

 and a narrower one adjoining the base of the dorsal. The 

 rest of the side has a plum-purple tint, besprinkled with 

 dark, violet-coloured dots. The head has also a purple 

 hue, and the oblique, pale stripe on the cheek, is bounded 



above and below with dark marks. The first dorsal is, as 

 is most usual, black posteriorly ; there are small obscure 

 spots on the second dorsal, and a dark line crosses the 

 anal rays near their ends. These colours are described 

 from specimens kept in spirits. 



The scales along the middle of the sides are finely and 

 equally ciliated ; the teeth of the upper and lower ones 

 are more minute, and are nearly concealed by the epider- 

 mis ; while, towards the middle of the belly, and on the 

 top of the back, the teeth of the scales become quite 

 obsolete. 



The jaws are armed with a single series of slightly 

 curved subulate teeth, which are tallest in front. In the 

 up])er jaw only, there are three or four interior teeth in front, 

 as tall as the others. The vela are softly granular and 

 porous, as in other species. The head forms a fourth of 

 the total length of the fish, caudal included, and the 

 height of the body is equal to a fifth of the length. 

 Length, b^ inches.

Plate* XII., figs. 3, 4, natural size. 



This fish has the same kind of bar on the cheek, and 

 line across the base of the pectoral, which we observe in 

 N. cornucola and virgata, and the head is even less scaly, 

 there being only five or six small deeply imbedded scales 

 scattered along the line of junction of the gill-cover with 

 the cranium. There are none on the supra-scapular re- 

 gions, and the top of the supra-scapular itself can with 

 difficulty be traced through the integument. Open pores 

 exist on the same parts of the head as in the species 

 named above, viz. across the snout and nape, along the 

 upper hinge of the gill-cover, round the eye, along the 

 limbs of the lower jaw, and up the edge of the preopercu- 

 lum. One of the nasal openings has an elevated tubular 

 mouth situated just before the eye. If there be a second 

 opening, it cannot be distinguished from a pore. The gill 

 membranes are united beneath, as in the others, the free 

 edge over the isthmus being a segment of a circle. The 

 pale borders of the anal and dorsal fins form a ready dis- 

 tinctive mark of the species. These fins are otherwise 

 blurred or blotched with black, but the colours of the fish 

 have faded in the spirits. 



The scales of the body are strongly ciliated, except 

 those which are on the top of the back, and on the belly, 

 and near the anal fin, where the teeth become obsolete. 

 The scales of the lateral line are notched at the tip, and 

 have a tube on the disk. There are forty such scales on 

 the fore part of the line, and ten on the posterior part. 



* It is due to Mr. Mitchell to say, that from a mistake in preparing 

 this plate, which was partly executed in lithotint, the drawings have 

 been considerably injured.
