The eye-stalks are short and stout, less than one-third the length of the 

 carapace, and gradually increase in diameter towards the expanded cornese ; 

 dorsally they are crested by a line of long hairs ; the ophthalmic scales are acute. 

 The antennulary peduncles exceed the eye-stalks by the whole length of the 

 terminal joint. The antennal peduncles are but slightly longer than the eye- 

 stalks; their basal joint is expanded and has the usual strong spine at the antero- 

 external angle ; the antennal acicle is doubly curved, with the inner margin 

 setose and strongly serrated ; its point reaches just beyond the origin of the 

 flagellum ; the last is not far short of twice the length of the body. 



The chelipeds are most remarkably unequal, the right exceeding the left in 

 bulk many times and in length by somewhat more than its daetylopoclite ; both 

 are pubescent above, and the right is sharply granular above and slightly so 

 below. In the right cheliped the meropoiite and carpopodite are also pubescent 

 below, and the margins of the latter, like those of the palm and fingers, are 

 closely and sharply serrated, the inner margin of the palm having a double row 

 of denticles. The left cheliped is hardly more massive than the corresponding 

 portion of the second or third leg, and is smooth throughout. In the second 

 and third legs the upper borders of the merus, carpus, and propodite are crenulate 

 or bluntly serrate, and, like the upper border of the long sinuous dactylus, hairy. 



A common species, inhabiting many kinds of Gastropod shells, which are 

 usually encrusted with a sea-anemone. 



From the Bay of Bengal, 145-250, 240, and 281-258 fathoms; the Andaman 

 Sea, 405 fathoms; and the Arabian Sea, off Ceylon and the Malabar coast, 

 142-400, ^24-284, 360, and 464 fathoms.

Differs from Parapagurus in the following characters only : 



The rostral prolongation is a little more pronounced. The eyestalks are 

 short. 



Though the great chelipeds are unequal they are not so markedly unequal, 

 the right being bulkier but not much longer than the left. 



In the male the vas deferens protrudes as a short curved tube from the 

 coxa of the 5th thoracic leg, and the first two abdominal somites are destitute of 

 appendages.
