The dorsal surface of the carapace is smooth and as a rule highly polished ; the 

 abdomen is very obscurely rugose. The breadth of the carapace, measured behind 

 the antero-lateral angles, is barely half its length, excluding the rostrum. The median 

 carina is distinct in front of the cervical groove (fig. 30), but is obsolete anteriorly. 

 The small median dorsal pit is clearly visible and is placed nearer to the cervical groove 

 than to the anterior margin. The intermediate carinae are well-marked ; the lateral 

 also are well-developed anteriorly and posteriorly, but are usually obsolete in the 

 middle. The antero-lateral angles terminate in stout spines which, owing to the strong 

 convexity of the anterior margin, fail to reach the level of the rostral base. Beneath 

 each antero-lateral spine there is a small blunt or subacute lobe. The postero-lateral 

 angles of the carapace are rounded. 



The rostrum is a trifle longer than broad ; its straight lateral margins are not up- 

 turned and converge to a rounded apex. Dorsally the rostrum is smooth except for 

 a sharp and distinct median longitudinal carina in its distal half. 



The eyes are small and elongated ; the breath of the cornea is about equal to the 

 length of the stalk (cornea excluded) , and the corneal and peduncular axes are decid- 

 edly oblique. The antennular peduncle is short, scarcely two- thirds the length of the 

 carapace. The two basal segments of the antennal endopodite are also short, the distal 

 one not reaching to half the length of the scale. The mandibular palp is wholly 

 absent. 



The outer inferior margin of the merus of the raptorial claw is bluntly rounded 

 anteriorly. The carpus bears the usual groove on its external aspect and its dorsal 

 carina is entire and terminates acutely before reaching the distal margin. The distal 

 end of the propodus is considerably broader in the male than in the female. The 

 dactylus bears five teeth including the apical one. The outer margin is furnished with 

 a small proximal lobe ; it is convex in the male but distinctly sinuous in the female. 



There are faint submedian and strong intermediate carinae on the last three 

 thoracic somites. The fifth somite bears a pair of broad tooth-like lobes inferiorly ; the 

 lateral lobe consists of a single strong falcate process terminating in a sharp forwardly- 

 directed spine. An oblique carina, which commences on the dorsal aspect of the 

 somite in the position usually occupied by the intermediate carina, extends down- 

 wards and is continuous with the posterior margin of the process. The antero-lateral 

 margins of the fifth somite are elevated and form a distinct ridge. The lateral margins 

 of the sixth and seventh somites are rounded; the eighth projects as a blunt 

 anterior lobe. 



The first five abdominal somites possess four pairs of longitudinal carinae, but the 

 submedians are not very strongly marked. The two median pairs of carinae on the 

 sixth somite are distinctly swollen in the male. The following carinae end in spines : —
