pace terminating just above the sharp branchiostegal spine. Thi^ 

 spine reaches to the level of the rostral apex and extends far in 

 advance of that which defines the outer orbital angle. Except for 

 those on its frontal margin the carapace is entirely devoid of 

 spines and, except for that in the mid-dorsal line, it is without 

 carinae. The carapace does not appear to be pubescent. 



The basal segment of the antennular peduncle is about one 

 and a half times the length of the second and third combined; its 

 lateral process is oval (text-fig. 2a). 



The antennal scale differs notably in the two sexes In the 

 female (text-fig. 2h') it is scarcely more than twice as long as broad

and the lamella, though narrowed, is of considerable breadth at 

 its distal end. In the male (text-fig. 26), it is almost three times 

 as long as broad and the lamella slopes sharply away from the 

 base of the distal tooth. The outer margin in both sexes bears 

 numerous spines, in this respect differing from all known species 

 of the genus. In the female the margin is straight or very shghtly 

 concave and bears some 12 or 13 spines which increase in size from 

 behind forwards. In the male the margin is strongly sinuous, 

 convex in the middle and concave towards the distal end. It 

 bears from 9 to 11 spines, similar to those of the female, but they 

 are restricted to the basal convex portion of the margin and do 

 not extend on to the concave part nearer the apex.
