R. yranulosa is in many respects close to R. tuberculosa, Eich., 

 but is clearly distinguished by the weaker sculpturing on the body, 

 the shape and armature of the 6th joint of the first 3 pairs of 

 peraeopods and the acute apex of the outer ramus of uropods. 

 The last but one character and the absence of ornamentation on 

 the telson serve to distinguish it from R. signata, Sch. & Mein., 

 and li. aries, Sch. & Mein.

(ovigerous ? ). 



Among several specimens of N. cephalotes, Sch. & Mein., collected 

 by the s.s. " Pieter Faure," are two specimens which agree with the 

 description and figures of N. rhabdota given by the joint authors 

 except ia one respect : the inner ramus of the uropods. According to 

 the description it is " narrow, obtuse, extending only a little beyond 

 the apex of telson," whereas in one of the South African specimens 

 (immature 5 ) it resembles the inner ramus of N. cephalotes, i.e., 

 it is acute, with a tooth on inner distal margin, but it does not 

 extend so much beyond the telsonic apex as in the latter species. 

 In the other specimen both inner rami are broken off short.
