The last pair are much longer than the last pair but one, being, in fact, 

 very little shorter than either of the first two pair. 



Abdomen as in B. Bumphii. 



The sternal grooves of the female approach one another closely, 

 but do not actually meet, on the 2nd segment of the sternum, near the 

 anterior end of which they terminate, without tubercles. 



In the Indian Museum are 5 females and 2 males, from the Anda- 

 man s and Mergui. 



The length of the carapace of the largest specimen is 28 millim. 



This species may perhaps turn out to be identical with Bromia 

 indica Gray (Zool. Miscell., p. 40).

Carapace etc. densely tomentose. Carapace about as long as 

 broad, strongly convex, with some dimples when denuded, two of which, 

 separating the post-gastric from the branchial regions, are specially 

 conspicuous. " Cervical " groove well marked. 



Front cut into two broadish but sharp teeth, between which, but on 

 a very much lower plane, is an extremely inconspicuous denticle. 



Abroad tooth ("internal supra-orbital angle") near the middle 

 of the upper border of the orbit. Outer orbital angle prominent but 

 not dentiform. Suborbital lobe bluntly dentiform, but not prominent. 



Antero-lateral borders entire, rather sharp. A slight projection, 

 hardly amounting to a tooth, on the postero-lateral border, immediately 

 behind the branchial or " cervical " groove. 



Chelipeds smooth, except for two tubercles at the far end of the 

 outer surface of the wrist. 



The fourth (last) pair of legs are not so very much shorter than 

 either of the first two pair and are very much longer than the 3rd pair. 

 The propodites of the last two pair are much broader than long and are 

 very spiny, one of the spines in the case of the last pair being as least 

 as long as the spine against which the claw-like dactylus closes — so 

 much so, that the last pair of legs appear to end in 3 claw-like spines 

 the middle one being the dactylus.
