This form is very closely allied to -I. .•«•/<//////m//"N, from which it is best distinguished by the less prominent front : the smaller and nearly equally prominent frontal teeth; the shorter and weaker pos- terior lateral spines ; and by the small or nearly obsolete posterior distal spine of the merus of the ehelipeds. The ehelipeds are also longer. Some of our specimens (No. 4035) were catalogued as .1. spiniriKunis by Prof. S. I. Smith, who depended on the figure of A. The type specimens, here described and figured, are from that lot. Measurements of Types and Cotypes. ipeds height s Locality Off Hatteras Off Hatteras Ft.
