carpus is longer than the carpus, feebly tapering towards the apex, the margins are smooth. 

 The dactylus is long, feebly curved, smooth, almost half as long as the metacarpus. 

 Glands in all the joints. 



The pleon is about as long as the whole perseon, the first segment is considerably 

 longer than the last two pergonal segments together. The lateral parts of the pleonal 

 segments are deep, evenly rounded below. 



The peduncles of the pleopoda are very large and thick, longer than the rami; the 

 outer ramus has ten joints, the inner nine. 



The urus; the first joint is longer than the last coalesced one. The whole urus is 

 longer than the last pleonal segment. 



The first pair of uropoda. (PI. VII, fig. 31) do not reach to the apex of the last pair; 

 the peduncle is somewhat broader at the apex, nearly three times as long as broad, and a 

 little longer than the inner ramus; the outer ramus is somewhat shorter than the inner 

 one, the outer margin is smooth, the inner sparingly set with fine, spine-like teeth; the 

 inner ramus is armed in the same manner on both margins. The second pair reach 

 almost to the apex of the last pair; the peduncle is considerably broader below than above, 

 three times as long as broad at the apex, and much longer than the inner ramus; the 

 outer ramus is shorter than the inner one; both rami are armed as those of the first pair. The 

 third pair have the peduncle broader than in the preceding pairs, not twice as long as 

 broad, but considerably longer than the last ural segment; the outer ramus is longer than 

 the inner one, both margins are set with fine, spine-like teeth; the inner ramus is a little 

 longer than the breadth of the peduncle, armed as the outer one. 



The telson is triangular, with curved margins, as long as broad; it is shorter than 

 the breadth of the peduncle of the last pair of uropoda.

The head is longer than the first two personal segments together. The tibial process of the first 

 pair of perawpoda is very short; the antero-inferior corner of the metacarpus is produced, form-
