Body closely beset with short knobbed hairs, among which longer 

 setae are interspersed. 



Carapace subpyriform, armed with numerous long sharp spines as 

 follows: — four, arranged in a triangle base forwards, on the gastric 

 region ; one on the cardiac, and one (very large) on the intestinal 

 region ; one on either hepatic region ; two or three on either pterygo- 

 stomian region ; and, finally, on either branchial region three dorsal and 

 three lateral : between these large spines some spinules and sharp 

 granules are interspersed. In the male there is a pair of strong spines 

 on the sternum between the chelipeds ; and each abdominal tergum has 

 a strong median spine : in the female five parallel rows of spines are 

 found on the ventral surface, three of which belong to the abdominal 

 terga, and one on either side to the sternum. 



The rostral spines are short (about one-fifth the length of the 

 carapace in the male, and rather less in the female), and divergent: 

 the accessory spinule is found on their inner margin near the tip. 



The basal antennal joint has a sharp spine at its antero-external 

 angle, and a tooth near the middle of its outer margin. The antero- 

 external angle of the prominent supra-ocular eave is surmounted by a 

 sharp spine. 



The chelipeds in the female and young male are rather more 

 slender than the other legs, and are a little longer than the carapace 

 and rostrum : the palms are slender and subcylindrical, and are nearly 

 three times as long as the fingers, which are nearly straight and appos- 

 able throughout. The ambulatory legs are slender, and have very long 

 slender dact3'li : the first pair, which are much the longest, are 'nearly 

 three times as long as the carapace and rostrum. 



In the Museum collection are specimens from the Andaman Sea 

 down to 40 fathoms.

Carapace broadly subpyriform, spinose. Rostrum formed of two 

 spines which are coalescent in their basal half. The commencing orbit, 

 which does not afford much concealment to the fully retracted eye, is 

 formed by a little-prominent supra-ocular eave, and a cupped (and 

 isolated) post-ocular tooth. The basal antennal joint is broad, has its 

 antero-external angle more or less produced, and has also a lobe on its
