108 CRUSTACEA MALACOSTRACA. II. 



long as deep. - - Five anterior abdominal segments (fig. i h) proportionately longer than in the females, 

 with the pleopods somewhat long, well developed. 



Remarks. C.arctica is allied and rather similar to C.abbreviata G. O. S., but according to 

 Sars' text and figures and my examination of a Norwegian specimen given by him C. abbremata is 

 smaller than C. arctica, its pleopods have no setae on the end of their rami, the exopod of the uropods 

 is one-jointed and, what is of special importance, the chelipeds are rather different, having the carpus 

 only one- third as long again as deep and the chela distinctly broader, two and a half times as long 

 as broad, with a single setae on the posterior margin. 



In vain I have looked for differences of possibly specific value between the specimens from 

 my very different localities; my type from the Kara Sea agrees completely with the specimens from 

 East Greenland and from the "Ingolf" Stations. Some among the specimens from the "Ingolf" 

 Stat. 25 are larger than the others and, as already stated, have the pleopods less developed than all 

 other specimens seen, but no other difference could be discovered. 



Occurrence. It has been taken by the "Ingolf at nine stations.

 land, especially East-Greenland, and off Jan Mayen by various Expeditions.

Distribution. The type of C.arctica was taken in the Kara Sea, 64 fm. (H. J. H.). Later 

 Stebbing has mentioned specimens from Novaia Zemlia or Spitzbergen, 100 fm. Recently it has been 

 mentioned by Sars from the Gaase Fjord, Ellesmere Land (at ab. Lat. 78 N., on the western side of 

 Smith Sound), 60 m. (2 d Fram Exped.). 



The geographical and bathymetrical distribution of this species is very interesting. In the 

 Kara Sea, at East Greenland, Jan Mayen and in Smith Sound it has been taken in depths between
