Diagnosis. — Chelipeds and anterior half of carapace rough. Mar- 

 gins of legs spinulous. Second lateral tooth almost indistinguishable. 

 A subhepatic tubercle present. A thin laminate crest above dactyls 

 of chelipeds. 



Description. — Carapace naked, distinctly areolated; anterior and 

 antero-lateral areolets somewhat roughened in front with small, sharp, 

 tooth-like tubercles which are partly disposed in lines. Antero- 

 lateral teeth sharp and denticulate, the posterior one nearly obsolete, 

 the first and second almost entirely fused, the second represented by 

 a denticle. Frontal lobes abruptly deflexed, Httle projecting, but 

 with a convex outline; margin thin, minutely crenulate and defined 

 by a slight furrow following it above. A small tubercle on the sub- 

 hepatic region beneath the second antero-lateral tooth.
