than the 2 succeeding pairs, basal joint of the 3 posterior pairs rather tumid.
Uropoda equalling in length about y3 of the meta.sniiie, both rami distinctly bi-
articulate and somewhat unequal, the outer one being shorter and narrower than
the inner. Length
1.65 mm.
Remarks. - - This form was discovered during the Norwegian North Atlantic
Expedition, and has been described and figured in detail by the present
author in
the Report of the Crustacea from that Expedition. It is easily distinguished from
any of the previously described species by its comparatively short and thick body,
the acutely produced frontal margin, and the comparatively long bristles issuing
from the tip at' the superior antennae.
Occurrence. - - A few female specimens of this form have been taken by
me at Kvalo on the Nordland coast, from depths of 60 100 fathoms.
Distribution. Stat. 290 of the Norwegian North Atlantic Expedition,
lying W. of Finmark.

Typhlotanais penicillatus, (I. O. Sars, 1. c. p. 39.
-
9- Body a little more slender than in T. cornutus,
being almost 5 times as long as it is broad. (Jephalosome not nearly
so broad
as in the said species, and having the frontal edge less strongly produced in the
middle. First and last segment of mesosome of about same size and somewhat
shorter than the others, which are separated by rather conspicuous constrictions.
Metasome of almost uniform breadth throughout. Superior antennae extremely
slender and narrow, considerably exceeding in length the cephalosome, terminal
joint linear and tipped by slender bristles, one of which is of quite
an unusual
length. Chelipeds slender and feeble, hand very narrow, sublinear, exceeding in
length the carpus, fingers nearly as long as the palm. Pereiopoda resembling in
structure those in T. cornutus, basal joint of the 3 posterior pairs, however, less
tumid. Uropoda with the inner ramus distinctly Inarticulate, the outer one uniarticulate
and somewhat shorter. Length 1.40 mm.
Remarks. - - This species is nearly allied to T. cornutus, but is of somewhat
more slender form, and moreover easily distinguished by the much feebler struc-
ture of the chelipeds, and by the extremely slender superior antennae, with their
long terminal pencils of bristles. Also the uropoda differ essentially in the fact
of the outer ramus being uniarticulate.
