is quite curved and has a very large basal molar, followed by a series 

 of three medium size and two very small teeth. The lower finger has 

 three large teeth and four or five smaller ones. There is a faint, longi- 

 tudinal groove on the outer surface of the upper finger. 



The second, third and fourth pairs of legs are slender, smooth, the 

 meral and carpal joints, compressed cylindrical; the propodus and 

 dactyli much more compressed and having their lateral margins 

 fringed with short setae ; the dactyli are long, tapered, with two deep, 

 longitudinal grooves on the lower surface and one on the upper sur- 

 face. The fifth pair of legs have the proximal joints stout, the pro- 

 podi and dactyli flattened into subovate, wide swimming paddles, 

 margined by a dense fringe of setae.
