 P. U. S. Nat. Mas. XIV. 1891, p. 380. 



Carapace two-thirds as long as broad, decidedly convex fore and 

 aft, its surface perfectly smooth to the naked eye, and bald. The gastric 

 region and its three sub-regions are as faintly as possible indicated, and 

 the two broken series of transverse elevations present in H. indiea are 

 also present, but are much blunter smoother and fainter. The orbits 

 are as in H. indiea, but the margin is but microscopically granular. 



The antero-lateral border is cut into four teeth, all of which are thin 

 and compressed, and all but the first are sharply acuminate forwards. 



The chelipeds are extremely unequal, and are perfectly smooth and 

 bare : there is a denticle at the distal end of the upper border of the 

 arm, and a stout sharp tubercle (often double-crowned) at the inner 

 angle of the wrist. The greatest length of the larger hand, in the 

 male, is about equal to the greatest breadth of the carapace, and its 

 greatest height more than three-quarters the greatest length of the 

 carapace : in the female this hand is not quite so large. 



The edges of the last four joints of all the legs are scantily hairy 

 in the male, but more profusely so in the female. 



Colours in spirit ; brownish yellow or dull green. 



In the Indian Museum are 17 specimens from Karachi and one 

 from Bombay. 



133. Heteropanope eucratoides, Stimpson.

 de Man, Jonrn. Linn. Soc, Zool., XXII. 1887-88, p. 56, pi. iii. figs. 3, 4. 



This species is included by de Man in the Mergui fauna. There 

 are no specimens in the Indian Museum. According to de Man it 

 chiefly differs from H. indiea in having the antero-lateral margins much 

 shorter, and the 3rd tooth of the antero-lateral margin smaller than 

 any of the others. 



The chelipeds have a smooth surface.
