amongst which are shorter and thicker spine-like hairs, which 

 spring from minute sockets : the distal end of the inner ramus 

 also bears a tuft of hairs. The rami reach much further 

 than the telson.

The animal is moderately compressed laterally and mode- 

 rately robust. 



The carapace is smooth, well produced latero-posterior- 

 ly ; it is about equal in length to the first three segments 

 of the pleon. The rostrum is very short — merely a spine — 

 slightly depressed, not reaching to half the length of the 

 ophthalmopods, transversely broad at the base but soon 

 tapering to an acute point, tipped with a few hairs and 

 very obscurely bifid. The antero-lateral borders of the cara- 

 pace are produced to subacute angles just below the eyes, 

 but there are no spines, the antero-lateral angles are rounded. 



The pleon has the second, third, and fourth segments 

 dorsally subequal in length, the rest are shorter. The pleura 

 are moderately deep, that of the first segment is well pro- 

 duced anteriorly, somewhat acutely, and overlapping the 

 carapace, that of the fifth has a small tooth on its lower 

 margin. The posterior angle of the sixth is very acute, and 

 there is a small rounded lobe projecting over the base of the 

 telson. 



The antennule has the first joint very much compres- 

 ed in the vertical direction, curved and excavate, strength- 

 ened by a strong keel below, with a transverse fringe of 

 hairs at the upper distal end, it bears a short, broad, lamel- 

 lar, and truncate stylocerite, whose outer distal angle ends 

 in a small acute tooth, which does not reach to half the 

 length of the joint. The second and third joints are sub- 

 equal in length, and together are shorter than the first. The 

 upper flagellum has the tliickened portion slightly longer 

 than the peduncle, it terminates in a short, slender portion. 

 The lower flaeellum is slender and about twice as long as 

 the upper. 



The ophthalmopods are large, pyriform. being verv slen-
