is carinate and serrate with coarse granules. The fingers are deflected 

 and the outer surfaces are greatly incurved ; the lower finger is the 

 larger, triangulate, with the cutting edge shallow serrate and tip in- 

 curved. The upper finger is more diagonal in position, slenderer, the 

 cutting edge entirely serrate, meeting throughout its length upon the 

 lower finger; the upper margin emphasized by rough granules and a 

 secondary row of granules below this on the outer surface. The 

 smaller cheliped is similar but much slenderer, the palm being not so 

 high, the fingers longer in proportion and the fluted effect on the outer 

 surface of the upper finger is distinct. 



The ambulatories are all very long and slender, their length de- 

 creasing in the order 2, 3, 1, 4, the second and third pairs being almost 

 equal. The meral, carpal and propodal joints are coarsely granulose 

 on the upper portion ; the propodi have a shallow, median longitudinal 

 groove on the outer surface and the dactyli, which are very long, slen- 

 der and delicately tapered are also fluted.
