Lobules of carapace moderately convex, their surface so much 

 wrinkled aud dented transversely as to give them an almost scaly look. 



Antero-lateral borders cut into six teeth, the edge between all the 

 teeth being granular. 



The orbital margin is granular, and there is a denticle to mark the 

 outer angle of the orbit. 



The nodules of the wrists and hands — and, to a less strongly 

 marked extent, those of the corresponding joints of the legs — are 

 granular, as are the hollows between the nodules ; and the two wrinkles 

 along the lower outer surface of the hand are granular. The fingers 

 resemble those of E. melissa, except that their surfaces are strongly 

 granular. 



Colours of well-preserved spirit specimens : yellowish with purplish 

 spots and blotches, many of which are confluent ; fingers and hand 

 coloured as in E. melissa. 



In the Indian Museum are 3 specimens from Persian Gulf and 

 Andamans, (besides one from Samoa).
