close to the small mid-dorsal pit. The lateral margin is obtusely angled in front of 

 the rounded postero-lateral corners as in 5. foveolata. Both carapace and abdomen 

 are deeply and rather coarsely punctured. 



The lateral margins of the rostrum are upturned and converge to a truncate apex. 

 The corneal portion of the eyes is greatly expanded and is set obliquely on the stalk. 

 The corneal index varies from 37 to 4-2 and in one specimen, which is quite excep- 

 tional among Indian examples, is as much as 49. The anterior margin of the 

 ophthalmic somite is rounded. 



The outer inferior margin of the merus of the raptorial claw terminates in a rounded 

 angle, and is not toothed. The dorsal carina of the carpus is entire or with a very 

 obscure tubercle and ends abruptly before reaching the anterior margin. The outer 

 margin of. the dactylus is evenly convex throughout its length and the teeth on its inner 

 margin are long and slender. 



The anterior of the two spines on the margin of the fifth thoracic somite is 

 situated at a lower level than the posterior. The lateral lobes of the sixth somite are 

 about equal in length and breadth ; the posterior lobe is sharply pointed, the anterior 

 more or less obliquely truncate. Both processes of the seventh somite are acute, the 

 anterior being both shorter and narrower than the posterior. 



As already mentioned the lateral carinae of the first five abdominal somites are 

 sharply bicarinate. This unusual feature is very distinct in adults and the narrow 

 area between the two carinulae is coarsely pitted ; in very young individuals the 

 bicarination is inconspicuous. The following abdominal carinae end in spines : — 



Carinae. Abdominal somites. 



Submedian . . . . . . 5, 6. 



Intermediate .. .. .. 3,4,5,6. 



Lateral .. .. .. 1,2,3,4,5,6. 



Marginal .. .. .. 1,2,3,4,5. 



The marginal teeth of the telson are unusually long and the denticles are excep- 

 tionally numerous. Of the latter there are five or six submedians, twelve to sixteen 

 intermediate, 1 and one lateral. 



In the bifurcate process from the base of the uropods, the lobe on the outer margin 

 of the longer spine is small or obsolete in adults, but is usually quite distinct in-very 

 small specimens. 



In very young examples, also, the median projection on the posterior margin of the 

 carapace is exceptionally well developed and the rostrum, as noticed in small indivi- 

 duals of some of the preceding species, is more strongly narrowed anteriorly. 



A single very large specimen from Japan, the only individual known from any 

 locality outside the Bay of Bengal, differs from the Indian examples in the following 

 partictilars : — 



1 . The carapace is distinctly broader ; its breadth at the antero-lateral angles 

 is exactly half the median length. The median carina of the carapace is 



1 In one specimen, which appears to be abnormal in this respect, there are only ten intermediate 

 denticles.
