FISH. 143 
ConGER PUNCTUS. Jen. 
C. lateribus fasciis transversis fuscescentt-rubris, interstitiis angustis griseis : rostro 
brevi, obtuso; mazxillis subequalibus : pinnd dorsali initium supra pectoralem 
capienti: cute corporis puncturis parvis creberrimé aggregatis impressa. 
Form.—Body much compressed, except at the anterior extremity. Depth less than one-eleventh of 
the entire length. Head contained about seven and a half times in the same. Snout short 
and rounded. Jaws nearly equal, the upper scarcely longer than the lower. Gape scarcely 
reaching beyond a vertical from the anterior part of the eye. Teeth velutine. A row of very 
conspicuous pores round the edges of both jaws. The whole body, but not the head, thickly 
studded all over with small pores, much crowded, and appearing like pin-holes. 
The pectorals are rather more than half the length of the head. The dorsal commences 
immediately above them, and has a moderate elevation of about one-third of the depth. The 
vent isa little posterior to the termination of the first third of the length, and the anal is 
immediately behind it. The dorsal and anal unite to form a moderately pointed caudal. 
Length 3 ine. 3 lines. 
Cotourn—( In spirits.) Sides very regularly banded with fourteen or fifteen transverse reddish 
brown fascize: the fascize extend on to the dorsal fin, and are much broader than the inter- 
vening spaces. All the under part of the head, belly as far as the vent, an irregular patch on 
the cheeks, and the spaces between the bands on the sides, yellowish. 
Habitat, Tierra del Fuego. 
This appears to be a new species. The individual described above is quite 
small, and stated in Mr. Darwin's notes to be the young of another and larger 
specimen which he also captured, but of which he does not mention the exact 
size, and which unfortunately does not appear in his collection. He has, how- 
ever, mentioned the colours, which appear similar to those given above, and are 
as follows :—‘‘ Sides with transverse bars of chocolate and brownish-red, sepa- 
rated by narrow grey spaces.” Whether the form and proportions of the adult 
agree exactly with those of the young as above detailed must be left for future 
observers to determine. The colours, however, appear well to characterize the 
species, aided by the minute punctures with which the whole body is covered. 
This species was taken by Mr. Darwin at the roots of fucus, at the east 
entrance of Beagle Channel, Tierra del Fuego. The larger specimen is said to 
have been very active.
