lu tlie Indian Museum are 13 specimens, from the Persian Gulf, 

 Malabar coast, Coromandel coast, Gulf of Martaban, and the Andanians. 

 The carapace of the largest specimeu is 10 millim. long and 12 millim. 

 broad. 



In one very young specimen the eye is represented by a tiny speck 

 of pigment, as shown in de Man's figure, but in large specimens there 

 is no trace of this speck.

 Cai-apace of but moderate deptli, moderately convex fore and aft 

 ,ind but moderately declivous anteriorly : it is a good deal broader than 

 long and inclines somewhat to a semicircular outline, the greatest 

 breadth being quite posterior, the postero-lateral borders being anteriorly 

 convergent, and the antero-lateral borders being nicely curved : the 

 regions are distinctly mapped out by fine grooves. 



Fronto-orbital boider about two-fifths, front about a fourth the 

 greatest breadth of the carapace: fi'ont rather obscurely bilobed, antero- 

 lateral borders acute. 



Eyes minute, eyestalks fixed in small orbits which lie entiiely 

 beneath the atiterior border of the carapace. The antennules fold 

 transversely in shallow and rather inadequate pits. Basal antenna-joint 

 short ; the flagellum, which is of moderate length, stands quite clear of 

 tiie orbital hiatus. 



Epistome sunken, not well demarcated from the edge of the buccal 

 cavern : the latter is squarish and broader in front than behind. There 

 is a considerable gap between the external maxilHpeds, the merus of 

 which is square and has a sharp antero-external angle and carries the 

 flngellum at the antero-internal angle. 



Chelipeds a little unequal, much shorter and not much more massive 

 (except as regards the larger palm) than the third pair of legs : palm 

 short and compressed, with sharp edges. 



The legs have the merus broadened, especially in the case of the 

 2iid and 3rd pair : the 3rd pair is considerably the longest. i - S ^ 



The abdomen consists of 7 separate segments, and does not nearly V-ra <tv " - 

 occupy all the sternum between the last pair of legs. V^"' 



Distribution : Indo-Pacific, from Madagascar to China.
