respectively, while their dorsal and ventral edges have become 

 upper and lower. 



The abdomen of the male is only five-jointed, the third, 

 fourth, and fifth joints being ankylosed together. That of the 

 female has the full number of distinct joints ; the abdomen and 

 sternum securely interlock, the sterna of the latter giving off 

 a forvvardly-increasing series of laminar processes which pro- 

 ject downwards and inwards over the edges of the former; 

 there is an erect spine on the sternum between the genital 

 apertures, and the spacious brood-cavity communicates with 

 the branchial cavity by a hole near each posterior angle of 

 the thorax. 



The eggs are very small, and in the specimen examined 

 few. 



Colours in life : — Carapace deep pink, fading gradually to 

 pale straw-colour at the posterior margin ; legs pink, with the 

 articulations, like the chela?, white. 



Twenty-eight males at Station 96, 98 to 102 fathoms ; 

 previously obtained (ten females) off the Godavari Delta in 

 70 fathoms and (three males and one female) off the Malnin-

Carapace above covered tolerably thickly with unequally 

 large, rounded, submammillated, granulose tubercles, with 

 much smaller ones interspersed. Of the largest tubercles one 

 is on the hinder end of the prominent pterygostomian ridge, 

 three are on the lateral margin, and two on the postero-lateral 

 margin on each side. The regions are very distinctly marked 

 out by grooves, the cardiac being especially deeply circum- 

 scribed, and the hepatic being separated from the gastric by a
