depressions on the merus, each filled with fine pubescence, one similar 

 depression on the carpus near the outer margin, a median one on the 

 propodus and on the dactyl ; that of the latter is not pubescent. The 

 anterior lateral margins of the meral and carpal joints and both lat- 

 eral margins of the propodus and dactyl are finely setose. The dactyl 

 is strong, acuminate, horn-tipped. 



The natatory legs have the three proximal joints stout, fringed with 

 setae on the anterior margins ; the propodus and dactyl are subequal, 

 laminate, with the margins fringed with setae, and setose areas on the 

 broad faces.
