the rest of the carapace, more than twice the length of the supraorbital spines. 

 Antero-lateral borders of carapace with 7 spines. No spines on dorsum of 

 carapace except a curved transverse row immediately behind the rostrum, and a 

 spine on either side behind the bifurcation of the cervical groove. Posterior 

 border of carapace quite smooth. All the transverse ridges well developed and 

 ciliated. Cardiac area ill- defined. 



2nd abdominal tergum with a row of spinules on the anterior border : a 

 pair of minute spinules is sometimes present on the same border of the 3rd 

 tergum : the other terga are unarmed. 



In the external maxillipeds the distal end of the ventral border of the 

 ischium is produced to an acicular spine, and there is a similar spine of equal 

 size on the same border of the merus. 



The eyes are large, their major diameter being more than a fourth the length 

 of the carapace proper. 



The chelipeds in the male are about lj times, in the female about lj times 

 the entire length of the body : all the joints including the dactylus are spiny. 

 The 2nd pair of legs which are the longest are a little longer than the body, 

 reaching just beyond the base of the palm of the male and more than two-thirds 

 of the way along the palm in the female. In all the legs of the 2nd-4th pairs 

 both borders of the merus and the anterior border of the carpus are spiny, the 

 posterior border of the carpus terminates in a spine, and the posterior border 

 of the propodite is armed with a series of fine articulating spinelets. 



The dimensions of a male are as follows : length from tip of rostrum to 

 end of extended telson 23 millim., length of cheliped, 37 millim. In a female 

 of the same length the chelipeds are 29 millim. long.

The length and the greatest breadth of the carapace are nearly the same. 

 The almost horizontal rostrum is one-third the length of the carapace, and the 

 orbital spines, which are slightly inclined upwards, are two-thirds the length of 

 the rostrum, all three being very distinctly squamous. The anterior margin 

 of the carapace on either side of the rostrum is concave and without any
