spines almost confined to distal margiu. Maxillipeds normal, 4*^ Joint of 

 palp Short, not unguiform, tipped with spines. Gnathopods 1 and 2 sub- 

 chelate; gnathopod 1 much tbe smaller. Gnathopod 2, 5*^ Joint small, in d 

 sometimes coalesciug with the large 6*^ Joint, which is usually more eiongate 

 than in the Q , in both sexes having the front margin notched for spines. 

 Peraeopods 1 — 5, 2*^ Joint never veiy large; finger strong and curved. 

 Branchial vesicles tending to develop extra lobes or become twisted. Marsupial 

 plates of great size. üropods 1 and 2, peduncle and rami spinöse; one 

 ramus decidedly shorter than the other; 1 spine in the apical group very 

 long, üropod 3, a small hoUow plate facing the telson's lateral margin. 

 Telson entire, with a process on the upper surface carrying spinules.
