produced anteriorly into a prominent rounded lobe, a* in first gnathopods; merus with pointed proc- 

 ess ;it infero-posterior angle; carpus very much largei than in marmorala, with an angular posterior 

 projection which bears a tuft of seta-; hand elongate, thickened, curved backward, devoid of a basal 

 process, posterior margin somewhat concave and densely fringed with rather short, plumose set*; a 

 blunt projection near infero-posterior angle of hand; peduncle of first uropods with a spine at distal 

 end, which is less than half the length of rami; terminal uropods with rami very small, scarcely one- 

 fourth the length of peduncle; telson triangular, with rounded apex. In the female the second 

 antennae are much smaller than in the male, being only a little longer and but little stouter than 

 the first pair, and the body is broader in the middle; second, third, and fourth coxal ] It tes larger 

 and relatively deeper, being somewhat deeper than long; first gnathopods resembling those of male, 

 but with basal joint narrower; second gnathopods very much smaller than in the male, basal joint 

 relatively broader, and widening more toward distal end; merus broadly rounded and setose below; 

 carpus subtriangular, short, produced behind into a setose lobe; hand narrowly ovate; palm slightly 

 sinuate, the upper extremity with a pair of stout spines, between which the tip of the finger closes; 

 one or more stout spines and live or six tufts of seta' above these on posterior margin of hand.

Norway (Sars); Greenland (Kroyer); Labrador; Iceland; Siberian polar sea; Grand Manan 

 (Stimpson); Bay of Fundy (Smith); Marblehead Beach. Professor Smith states that "this species 

 was dredged by Professor Verrill in 4 to 5 fathoms off Watch Hill, R. I., in April, 1873." It seems to 

 be rare on the southern coast of New England. 



According to Stimpson, "the color varies from light olive or greenish to light crimson. Eyes 

 usually white. The articles of the antenna; are sometimes alternately red and white." Professor 

 Smith states that some of the specimens taken at Watch Hill "had a transverse dorsal band of red or 

 orange on each segment, and similar ones on the epimera, and were minutely speckled with dark 

 brown; the antenna" and legs were annulated with white and light red or orange.
