FISH 169 
Pieces of the gill-cover on the whole similar, but the branchial aperture much smaller, the 
fissure not descending below the level of the upper part of the pectoral: branchial membrane 
with six rays. Skin quite naked, and thickly studded all over with mucous pores. Also some 
very large and conspicuous pores in rows on the jaws and cheeks, but not elevated into cuta- 
neous tubes, excepting the nostrils, which are tubular. 
Dorsal and anal with all the rays articulated, and the greater part of them simple, but 
some toward the tail a little branched at their tips. Caudal not so pointed as in Iluoceetes. 
Pectorals and ventrals similar, but the latter a trifle longer and broader in proportion. 
Length 4 inc. 7 lines. 
Cotour.— (Jn spirits.) — Brown, with the jaws, under part of the head, and lower half of the cheeks, 
whitish ; also a whitish fascia extending longitudinally from behind each eye to the upper 
angle of the opercle. 
. A second specimen in the collection is smaller than the above, measuring only two inches 
and a half in length. It is in bad condition, but does not appear to differ, except in having 
the anterior canines above but very little developed. 
Habitat, Falkland Islands. 
Both individuals of this species were taken by Mr. Darwin in the Falkland 
Islands. “ Caught amongst kelp.”—D.
