Carapace thick and deep, approaching a quadrilateral shape, very- 

 little convex or nearly flat, not remarkably broader than long, the 

 regions except the gastric not demarcated. 



Antero-lateral borders slightly curved, much shorter than the 

 postero- lateral and meeting the latter, not at a strong angle as in most 

 Oancrids, but at a very open and imperceptible angle ; though spinate 

 they are not cut into lobes. 



The fronto-orbital border is extremely broad, much more than 

 three-quarters the greatest breadth of the carapace ; the front, which is 

 therefore broad also, is strongly deflexed, is almost straight, and is cut 

 into two broad lobes the outer part of each of which is broadly in 

 contact — far beyond the limits of the antennal base — with a singular- 

 ly broad prolongation of the infra-orbital plate. The orbits, which are 

 deep and oval, are therefore completely closed and widely separated 

 from the antennae. 



The basal antennal joint is very small short and broad ; the flagel- 

 lum is long, more than the major diameter of the large orbit. The 

 antennules fold transversely. 



The crests of the endostome, defining the expiratory canals, are 

 strong, and the canal is completed below by the foliaceous process of the 

 first maxillipeds, the anterior edge of that process being concave. The 

 oblique anterior border of the merus of the external maxillipeds is not 

 notched. 



Chelipeds massive, unequal in both sexes ; fingers stout, pointed, 

 not hollowed. 



The abdomen of the male has all 7 segments separate. 



Key to the Indian species of Eriphia. 



I. Carapace nearly ^ as long as broad, devoid of hair dor sally ; 

 front cut into blunt teeth : — 



1. Chelipeds smooth to the naked eye E. Isevimana. 



2. Hand and wrist of the smaller cheliped studded with 

 tubercles E. smithii. 



II. Carapace only f as long as broad, with numerous scattered 



hairs; front not cut into teeth E. scabricula.
