﻿South African Crustacea. 101 



simple branch. The second pleopod has two branches lying 

 so closely one on the other that they are with difficulty drawn 

 apart; in independent attachment to the peduncle is a process, 

 on the inner side of the inner branch, which carries a slender 

 piece about one-third the length of the ramus, having its 

 lanceolate end densely fringed with setae. To this piece on 

 the inner side near its base is attached a rather long 

 retinaculum, distally armed with numerous hooks, its blunt 

 end level with the base of the lanceolate apex just mentioned. 

 There are obvious differences between this arrangement and 

 the corresponding parts figured by Kemp for N. exilis. 



The peduncle of the uropods on the outer side is apically 

 acute. The inner ramus is lanceolate, much shorter than the 

 broad outer ramus, the setose outer margin of which meets 

 the sinuous faintly marked diaeresis with a very small tooth, 

 \vithin which is a larger spine, and beyond which the margin 

 is continued to form a broadly rounded apex, fringed like the 

 other available edges of both branches with long plumose 

 setae. Total length of specimen about 70 mm., rostrum 

 5 mm., carapace with rostrum 19 mm., telson 10 mm. 



Lecality. Cape Natal N. by E. 24 miles; depth 440 fathoms.
