appears to be allied to C. glacialis, Hodgson. 
It may be worth while here to give the names of the species included in the 
“ brevitarsal ” group as far as I have been able to collect them. They are C. gigas, 
leptorhynchus, minuta, and japonica of Hoek, colossea and macernma of Wilson, clavata,

Occurrence .—Station 294, Ross Sea, 158 fathoms; 1 $ (Holotype), 1 $. 
Description.—Trunk compact, its greatest width across the first pair of lateral 
processes more than two-thirds of its length ; lateral processes almost or quite in 
contact with each other except the third and fourth pairs, which are separated by a 
small interval; inter-segmental lines very indistinct. Ocular tubercle bluntly conical 
or rounded at the tip, not occupying more than one-third of width of cephalic segment; 
eyes dark, sharply defined, anterior pair hardly larger than posterior. On dorsal 
surface behind ocular tubercle is a convex area defined posteriorly by a crescentic 
groove ; no anterior tubercles on cephalon. 
Proboscis decurved, more than twice as long as trunk, narrow and cylindrical for 
the first quarter of its length, then expanding to nearly twice the width at about the 
middle, narrowing again to a slight terminal dilatation where it measures about five- 
sixths of its greatest width. Mouth-opening conspicuously wide, the labial teeth 
apparently smaller, or at least capable of further retraction than in allied species. 
Abdomen shorter than greatest diameter of proboscis, decurved, cylindrical, blunt. 
Palp with second segment a little less than twice as long as fourth ; sixth longer 
than fifth and nearly four times as long as thick ; seventh shorter than its width and
