the specimens from 1435 fatlioms in the warm area and specimens from depllis ranorinfj between 495 

 and 1060 fathoms in the cold area, and must therefore refer tliem all to tlic same species. 



Occurrence, l.iiiixhis has been taken by the "Ingolf at ten deep-sea station.s, with a single 

 exception in the cold area.

vSars' figures and description in his last-named work are on the whole good, but it nia\- be 

 useful to enumerate a number of features, b\- the combination of which this sjjecies is separated from 

 any other form. 



7; cormitus is thicker than most species, being about four and a half times as long as broad. 

 The carapace is a little or somewhat shorter than the three following segments combined, .^ntennulae 

 moderately slender, scarcely as long as the carapace, with the longest terminal seta; decidedly longer 

 than the two distal joints combined. Chelipeds with carpus and chela equal in length and somewhat 

 short in proportion to breadth; the movable finger a good deal shorter than the front margin of the 

 hand. — Second thoracic segment half or less than half as long as third segment, which is conspi- 

 cuously shorter than the fourth. Second pair of thoracic legs somewhat slender; sixth joint conspi- 

 cuoush- longer than the seventh with claw, with its distal posterior seta somewhat long. Second joint 

 of the posterior pairs of legs moderately thick. — Uropods with both rami two-jointed and the exopod 

 conspicuoush- shorter than the endopod. 



Among the cliaracters pointed out by Sars that drawn from tlie well-developed rostrum seems 

 to me less valuable, and it may be stated here that I have some co-types of Sars presented by him- 

 self. — In specimens with the ventral side of second thoracic segment convex a moderateh' small or 

 somewhat large process jirojects downwards and much forwards, originating somewhat behind the 

 front end of the segment. 



Occurrence. Taken b\- the "Ingolf" at a single station.
