A. Alcock — Carcinologieal Fauna of India. 
Basal antennal joint somewhat enlarged, and coalescent at its dis¬ 
tal extremity with the front ; beneath which the flagella are inserted 
out of sight in a dorsal view. 
The external maxillipeds are small, the merns distally truncated, 
and bearing the palp at its antero-internal angle. Chelipeds in the male 
moderately developed, with the palms compressed and cristate above, 
the fingers somewhat excavated at the tips, and not apposable through¬ 
out their extent. Ambulatory legs short—the longest pair not much 
longer than the chelipeds, dactyli short, stout, strongly recurved, and 
more or less toothed along the posterior margin.

Carapace flat, depressed, with two low elevations in the middle line, 
otherwise smooth: in the male the carapace is elongate triangular, with 
the lateral epibranchial angles produced to form small lobes, and some¬ 
times with the hepatic regions expanded in the same way: in the 
female the carapace is quadrilobate, owing to the foliaceous extension of 
the hepatic and epibranchial angles. Rostrum long, simple, acute, 
deep, and laterally compressed. Supra-ocular spines small. Eyes 
small, deeply sunk beneath the pre-ocular spine, almost immovable. 
In the male the chelipeds are somewhat shorter, and the next pair 
•of legs (which are the longest) are somewhat longer than the carapace 
and rostrum combined: in the female the chelipeds are considerably 
shorter than, and the next pair of legs are about the same length as, 
the carapace and rostrum. In the female and young male the fingers, 
which are closely toothed, meet throughout the greater part of their 
extent: in the male they meet only at the tips. 
The last three pairs of legs are very short. All the long joints, 
except the dactyli, of all the trunk-legs are more or less carinate dor- 
sally (anteriorly), the carination often being more or less discontinuous in 
the case of the chelipeds: the dactyli of the ambulatory legs are stout, 
strongly recurved, and more or less toothed along the posterior margin.
