smooth ; the lateral borders, which are conver^eut anteriorly, 

 are from six- to ten-spined ; tlie posterior border is raised and 

 is surmounted by a series of about ten spines ; the gastric 

 region bears a pair of spines at the base of the rostrum and a 

 row of spines along the middle line, and this row is contiiiut.Ml 

 along the cardiac region, some of the spines there being biliil 

 or trifid ; on the branchial regions arc numerous sharp 

 tubercles and spines. 



The abdominal terga and pleura; are glabrous ; the second, 

 third, and fourth terga are deeply channelled transversely, 

 the edges of the channel forming sharp and very evenly 

 spinate crests. 



The eye-stalks arc very short, free and freely movable, and 

 not prolonged beyond the ovoid cornese. 



The basal joint of the antennulary peduncles has three 

 large terminal spikes of nearly equal length. 



The spines on the joints of the aitennal peduncles are 

 remarkably distinct and the flagellum is about twice as long 

 as the body. 



The ischiopodite of the external maxillipeds is evenly 

 toothed along the inner edge and has a terminal spine on the 

 lower edge, and the meropodite has two spines near the 

 proximal end on the lower edge. 



The thoracic legs are granular, or squamous, or spinate. 

 The chelipeds are somewhat longer, but hardly stouter, than 

 the second, third, and fourth legs, and in the male they are 

 somewhat longer and in the female somewhat shorter than 

 the fully extended body (with the rostrum) ; all their joints 

 except the first and last are more or less thorny ; the tingers 

 are long, slender, and finely toothed, being in the male a 

 little longer than, and in the female about the same length as, 

 the palm. 



The second, third, and fourth legs have the anterior edge 

 of the ischiopodite and carpus thorny and the teeth on the 

 posterior edge of the dactylopodite small. 



The abdominal legs of all but the first two pairs are rudi- 

 mentary in the male ; those of the first pair are absent in the 

 female. 



Length of the male 40 millim., of the female 42 millira. 

 (measured from the tip of the rostrum).
