 Many specimens of a small Notothenia were collected 

 by the expedition, among the sea-weed that lines the 

 shores of Cape Horn. These specimens have suffered 

 much injury from deterioration of the spirit in which 

 they were put, and the figure is the result of a combina- 

 tion of the most perfect, one supplying what was wanting 

 in another. It is drawn to the dimensions of the largest 

 specimen. 



In general form the species resembles N. cyanobrancha. 

 The dorsal fins are distinct, but contiguous. There is a 

 band of deeply imbedded scales on the upper border of 

 the operculum, a few small ones on the temples adjoining 

 the upper end of the preoperculum, but none on the space 

 enclosed by the limbs of the supra-scapular. The tip of 

 that bone is creuated, and looks like a scale through the 

 investing skin. A row of pores completely encircles the 

 eye, and runs forward along the edge of the snout. Pores 

 also trace out the limb of the preoperculum, and run along 

 the lower jaw, and there is a single pore on the mesial line, 

 between the eyes. The interorbital space is narrower 

 than the width of the orbit. The posterior nostril is 

 shortly tubular ; the anterior one cannot be distinguished 

 from a pore. The scales on the bellj' are very small, and 

 between the ventrals they are confined to the middle third 

 of the space. On these parts they are not toothed, and 

 no teeth are visible on the larger scales above and behind 

 the vent. On the sides of the body and tail the scales are 

 strongly ciliated. There is no anal tubercle. 



The colours generally have faded. The cheeks and 

 bases of the pectorals are dark, the caudal, second dorsal, 

 and pectoral fins are finely mottled. The stomach is 

 pyriform, with a short, nearly cylindrical pyloric branch 

 springing upwards from above its middle. Round the 

 pylorus there are seven short cseca, and the intestine, in 

 its course to the anus, doubles once. The stomachs of 

 those which we opened contained small fish, crabs, and 

 crayfish.

On the 14th of January, 1842, when the ships were 



embayed among ice, in the 65th parallel of south latitude, 

 and about the 1 55th west meridian, a seal was taken with 

 twenty-eight pounds of fish in its stomach. The fish were 

 of two kinds, one a Spliyrana, the other a Notothenia, of 

 which there were many mutilated individuals. Dr. 

 Hooker made a careful drawing of the most perfect, and 

 put several examples in spirits, but they have become 

 still more deteriorated, though enough remains to leave 

 little doubt as to the genus, and even to show that the 

 species is distinct from any of the preceding ones, but 

 not sufficient to furnish materials for a correct desciiption. 



In the form of the head this fish closely resembles the 

 following, N. niagellanica, the orifice of the mouth in 

 both being more oblique than in the four species we have 

 figured. The dorsal line also is more arched, and there 

 is a corresponding curve of the ventral line posterior to 

 the anus. Anterior to that orifice, the belly, as in the 

 others, is rather protuberant, and, on that account, the 

 body is highest at the commencement of the second dorsal 

 fin, though the summit of the dorsal curve is so far 

 back as the ninth ray of the fin. This ray is, more- 

 over, the tallest, and the anterior and posterior ones 

 diminish very gradually in height, so as to give a flatly 

 curved outline to the fin. The first dorsal appears to be 

 as high as any part of the second one, but neither Dr. 

 Hooker's sketch, nor the specimens, enable us to deter- 

 mine whether the two fins were connected by membrane 

 or not. The second ray of the first dorsal is the tallest, 

 the form of the fin being the same with that of niagellanica. 

 The anal closely resembles the second dorsal, and both 

 fins have a slightly prolonged tip to the last ray. The 

 pectoral is similar in form and relative size to that of the 

 figured species, and the ventrals are also similarly placed. 

 The caudal was mutilated in all the specimens. Neither 

 the course of the lateral line, nor the presence or absence 

 of scales on the head, could be ascertained. The scales 

 of the body appear to have been tolerably large. Dr. 

 Hooker's notes state that they were deeply imbedded in 

 the skin. The jaw teeth are in narrow bands, and near 

 the middle of each limb of the lower jaw there is one a 

 little larger than the rest, which may be called a small 

 canine tooth. The partially digested fragments were 

 coloured " azure-blue, mixed with pale pink, the blue 

 stronger, brighter, and more silvered about the gill-covers, 

 jaws, and cheeks, mottled more or less with large black 

 spots, especially about the ujjper aspect of the head, the 

 belly, base of the pectorals, and shoulders. The black 

 pupil surrounded by a brilliantly iridescent iris, streaked 

 with azure-blue, silver, and carmine." Perhaps some of 

 the tints mentioned by Dr. Hooker may have been pro- 

 duced by the action of the gastric juice. 



The liver is pale red, very large, three lobed, and covers 

 the ventral surface of all the intestines, Its breadth above, 

 in a fish 6| inches long, is TOSinch. Below, when spread 

 out, it measures 2*40 inches. The left lobe, in situ, is 0'70 

 in length, the right one hangs down to the anus, and is \'7S 

 inch long ; the intermediate lobe is much smaller. The 

 vertically kidney-shaped stomach emits from its middle at 

 right angles a short cylindrical pyloric branch, 042 inch 

 long, and below the pylorus there are five cylindrical 

 obtuse caeca, the longest of which measures 035 inch.
