The carapace is roughly pear-shaped. It ends in front in a 

 large triangular rostrum, and is slightly concave on the hind 

 margin. Its surface is traversed by grooves running from one 

 side to the other ; they are bordered by fringes of fine setae. 

 The rostrum has four spines on each side but they are not all 

 well developed ; the last pair, especially, are very small. The 

 central point is longer than any of the lateral spines. The rostrum 

 is longer and narrower in the male than in the female. The lateral 

 margins of the carapace bear each a row of spines, of which 

 those at the antero-lateral angles are the largest. There is a 

 short, transverse groove surmounted by two spines at the base 

 of the rostrum, separating it from the gastric area. Below 

 the lateral margin there is a distinct linea anornurica, and 

 beneath the latter are a number of oblique grooves running 

 forwards and downwards. 



Each of the abdominal terga bears a single transverse furrow. 

 The pleura point slightly forwards, and are of equal size from 

 the second to the sixth segment ; in the first segment they are 

 much reduced and more or less hidden by the carapace. 



The telson is bisected by a longitudinal groove, and further 

 divided by lines running obliquely inward from the postero- 

 lateral angles. Its dorsal surface bears minute scales from which 

 spring groups of bristles and spines, all directed backwards. 



The eyes are small, and the eyestalks cylindrical, and partly 

 hidden by the rostrum. 



The basal joint of the antennules bears two long pointed 

 processes, from which spring a few bristles near the tip. On 

 the upper surface of the joint there is a deep groove into which 

 the distal portion of the appendage can be folded. When in
