Carapace broadly pyriform, with the surface granular and the later¬ 
al margins strongly spinate. The rostrum consists of two short stout 
slightly incurved spines, the outer border of which carries one or two 
accessory spines. The orbit is formed by a little-prominent supraocular 
eave, and a sharply bilobed post-ocular tooth, with a broad spine in the 
interval between the two : the eye-stalks are stout and the cornea ter¬ 
minal, not ventral, in position. The basal antennal joint is somewhat 
narrowed anteriorly, and ends in two sharp spines—as in the genera 
immediately preceding : the mobile portion of the antenna is freely ex¬ 
posed. Iu the external maxillipeds the merns is rather broader than 
the ischium, and the palp is attached to the antero-internal angle of the 
merns. 
The chelipeds have the merus and carpus granular or spiny ; the 
palm long, smooth and slender ; and the fingers longitudinally channel¬ 
led in their distal half—this being specially marked in the adult male, 
in which also the chelipeds are longer and stouter than the other legs. 
The ambulatory legs are stout, have cylindrical joints, and decrease 
gradually in length. 
The abdomen in both sexes consists of seven distinct segments.
