242 Carcinological Fauna of India. 



The diameter of the carapace of the male is 8 millim. 



Colours uniform blackish brown everywhere above and below. 



Loc. Godavari coast, Sacramento shoal, 6 fms., a single male : and 

 Persian Gulf, a male. 



In the specimen from the Persian Gulf the surface of the carapace 

 beneath the velvet-like pubescence is uniformly punctulate in honey- 

 comb fashion ; and the edges of the carapace, the epibranchial carina, 

 and the edges of the chelipeds and of their longitudinal ridge, as 

 also of the second ridge along the inner edge of the hand, are all evenly 

 granular. A near ally of this little species appears to be P. punctata, 

 Bell.

Carapace convex, subcircular, but pinched in to form an indepen- 

 dent marginal facet in either hepatic region : the circumference is beaded, 

 as also — but less distinctly — are the margins of the lateral hepatic 

 facets: the surface of the carapace, to the naked eye, is almost always 

 quite smooth : the branchio-cardiac grooves are distinct. 



The edge of the front is almost straight and is broadly bilobed, the 

 whole of the epistome projects beyond it. The edge of the epistome is 

 deeply cleft just below the eye, on either side. 



The thoracic sterna have the edges, and the first sternum the sur- 

 face also, beaded or granular. 



The external maxillipeds have the surface smooth, and the edges 

 of certain of their segments finely and inconspicuously fringed as in 

 P, globosa (Fabr.), only the hairs on the inner edge of the endognath 

 of the female being conspicuous : the distal segment of the exognath 

 is less dilated than in any other Indian species. 



The chelipeds in the adult male are 2i times, in the adult female 

 14 times, the length of the carapace : the arms have a few rather distant 

 small vesicular granules on the basal third of, and also along the inner 

 border of, the upper surface, and on the base and along the lower border 

 of the inner surface, besides other tiny granules only visible with a lens: 

 the surfaces of the wrist and hand are smooth. The hand is thin —
