FORM.—Snout rather compressed before the eyes, not very long, and
slightly obtuse. Upper jaw a very little in advance of the lower.
The gape extends behind the eyes, but the posterior portion is not
equal to the anterior. The teeth, tubular orifices, and pores, are
very much the same as in the species last noticed. Dorsal very
distinct, commencing in advance of the branchial orifice. Anal not
so distinct as the dorsal.
Length 5 inc. 6 lin.
COLOUR.—Brown, but with some lighter specks and mottlings, more
particularly on the lower jaw and on the fins.
Taken by Mr. Darwin at Tahiti. Probably a new species, but, as in the
last case, the specimen is young and not easily determinable.
