314 CRUSTACEA. 



Length of carapax, 3 lines; breadth, 3'85 lines; ratio of length to 

 breadth, 1 : T28. The fissures about the medial region are deep and 

 in part a little hairy. The carapax is granulous ; the tarsus is striated 

 and unarmed. There is a single emargination in the lateral margin 

 anteriorly, and this margin is somewhat hairy. The hand and the 

 stout tooth near base of moveable finger, are as figured by Krauss. 

 The other finger is slightly channeled, and a faint ridge extends from 

 it backwards over the surface of the hand. The abdomen of male 

 differs a little from his figure, in having the breadth hardly increased 

 at the penult segment, and hardly any more so at the third segment ; 

 the breadth slightly diminishes from the third segment towards apex. 

 The hand and fingers on the inner surface are densely hairy. The 

 abdomen and sternum are smooth, naked, and shining.
