Rodberg, 250-300 fathoms. 



In this species the leading character is " Segraentorum 

 thoracicorum 4 priorum margines anleriores in cristas sub- 

 tiliter crcnulatas elevati." Among the specimens occurring 

 at Rodberg are some in which this crenation is almost wholly 

 absent. I have also taken this species in the Varanger Fiord, 

 East Finmark, and have one of the original specimens pro- 

 cured by the describer at the Lofoten Islands.
