about three-fourths as long as broad, its greatest breadth across the 

 middle : when denuded it is granular in places and the regions are 

 hardly distinguishable. Three blunt granular teeth on the lateral 

 borders, two of which are antero-lateral, the third being postero-lateral. 



Front between a fourth and a fifth the breadth of the carapace, 

 bilobed : orbits piriform. 



Buccal cavern quite square : antero-external angle of merus of 

 external maxillipeds well marked but not produced, the exognath normal. 



Chelipeds about twice as long as the carapace, and nearly the same 

 length as the 3rd (longest) pair of legs, their outer surface, especially 

 that of the palm, is granular: inner angle of the wrist produced, denti- 

 form. The legs are fringed with coarsish hairs. 



In the Indian Museum, besides a specimen from Hongkong, are 

 6 from various parts of the coast of the Bay of Bengal. 



The carapace of the best specimen is G millim. long and 8 millim. 

 broad. 



In this species also there is a tiny speck of pigment for an eye. 



26. Typhlocarcimis rubidus, n. sp. 



Carapace perfectly smooth and nude, except for a few hairs on the 

 anterior and antero-lateral margins, its length a little over tliree-fifths 

 its breadth, the regions hardly distinguishable, though the epibranchial 

 regions have a decided dorsal bulge. 



The antero-lateral borders, which, like the postero-lateral are blunt 

 and granular, are quite entire. 



Front about a fifth the breadth of the carapace, bilobed, the median 

 groove very deep. Orbits piriform. Buccal cavern and external 

 maxillipeds as in T. villosus. 



Chelipeds and legs rather hairy, but there is always a large smooth 

 bare space on the outer surface of the wrist and palm. Clielipeds about 

 as long as the longest legs, less than twice the length of the carapace: 

 inner angle of wrist produced, dentiform : below and above the bare 

 patch on the wrist and hand the surface, when denuded, is granular. 



The colour is a rich ruddy brown. 



In the Indian Museum are 18 specimens from the Bay of Bengal, 

 20 to 65 fms. 



The largest specimen has the carapace nearly 7 millim. long and 

 10 millim. broad, but there are egg-laden females smaller than this. 



There is no pigment speck to represent an eye in this species.
