long- spines, one on each side of the median longitudinal line on each 

 segment, those on the sixth and seventh segments being nearer the 

 middle transverse line of the segment. The abdomen has one long 

 median spine near the base, and two rudimentary spines or tubercles 

 on the dorsal surface, just opposite the incisions in the lateral 

 margins. 



Only one specimen, a male, from Station 2043, steamer Albatross, 

 off Nantucket Shoals. It was taken at a depth of 1,467 fathoms. 



The type is in the U. S. National Museum, Cat. No. 38971. 



This species differs chiefly from Eurycope trim cat a, to which it 

 is closely related, in the presence of spines on the dorsal surface of 

 the body.
