slender and about the same length, the tip of the last pair reaching the 
terminal third of the rostrum; the extremity of the propodi is fringed with 
bristles ; the dactyli are slender; the proximal half of their concave mar- 
gin is furnished with 5 or 6 spinules so closely appressed that to the 
naked eye the dactylus appears unarmed; the distal spinule is long, 
and with the slender tip of the dactylus gives the appearance of a minute 
chela. 
The abdomen is non-carinated; the fourth segment is unarmed; the 
sixth segment is one and a half times the fifth; the seventh is a little 
longer than the sixth and armed with 5 or 6 spinules on each side.
