»Grreenland». By Smith ^ it has been mentioned as occurring 

 in the Gnlf of Maine, off the coast of Nova Scotia, and at 

 two raore stations oif the Atlantic coast of United States, in 

 depths ranging from 101 to 524 fathoms. The greatest depth 

 at which it has been dredged, was 672 fathoms (= 1229 m.), 

 in the inner part of Sogne Fiord. 



Although, at present, occurring but very rarely within the 

 Arctic Ocean, the species is, in all probability, of an Arctic 

 origin. Like Mumwpsis typica, Calathura brachiata and 

 others, it dwells now, since the great fiords of Norway have 

 been partly obstructed from free communication with the 

 €pen sea by submarine ridges, only in the very deepest hollows 

 of the fiords, where the conditions are most analogous with 

 those of the Arctic Ocean. 



Length of greatest spec. (a female with roe from stat. 41.) 

 ■64 mm. 



The eggs are, contrary to what might have been anti- 

 cipated in such a deep-sea form, small and numerous, although 

 relatively larger than in Crangon Allmanni. The cleavage 

 was just finished, but no formation of embryo was yet to be 

 observed, all eggs being about the same stage.
