slightly expanded and produced below into a shallow lobe. All 

 peraeopods with the sixth joint slightly expanded distally and ob- 

 liquely truncate ; the truncate end, which is provided with several 

 pairs of short, stout spines, forming with the dactyl a more or less 

 efficient subchelate grasping organ. A specimen of this species in the 

 National Museum collection, which was identified by Gurjanova, has 

 no spines on the telson. Her figure (1938, fig. 13-2) shows a spine 

 on each lateral margin. The specimens from Point Barrow, which 

 are mature males and females measuring about 6 mm., have no spines 

 on the telson. Gurjanova gives 90 m. for the depth for this species.
