Tuticorin, a female (Thurston) ; Madras coast (J. R. H.). 



The front is quadrilobed, with the median slightly smaller than the outer lobes, aud 

 the margin of all finely crenulated and fringed with long brown hairs. A median and 

 two lateral fissures on each side of the front are present, which, though obsolete, 

 extend some distance back on the carapace, and the most external arises from the 

 upper orbital margin. The carapace is minutely granulated anteriorly and towards 

 the sides. The lateral margin is crenulated, with a slight tooth about one third of the 

 distance back, and immediately in front of this the margin is slightly indented. The 

 hands are finely granulated externally, and long hairs are present on the legs and on 

 the meral joints of the chelipedes. 



The Tuticorin specimen is 137 mm. long and 15 mm. broad. 



Distribution. Chinese and Japanese Seas, ou a sandy bottom at a depth of 20-24 

 fathoms (Stimpson) ; Torres Straits (Miers).

Gulf of Martaban, a male (Oates) ; Madras coast, several specimens, including females 

 with ova (J. B. H.). 



I have compared these with the type-specimen in the British Museum, and can find 

 no difference except that the Indian specimens are somewhat smaller.

Gulf of Martaban, an adult female (Oates). 



I have compared this with typical specimens from Hong Kong, named by Stimpson, 

 and presented to the British Museum by the Smithsonian Institution. The carapace is 

 granulated and punctate, with an acute spinule at the posterior limit of the sharply
