 Key to the Indian species of Pagurodes. 



I. Eyestalks compressed, swollen at base, barely reaching beyond the 

 end of the 1st joint of the nntennular peduncle : the antennal acicle 

 reaches beyond the end of the autennal peduncle : under the lens the 

 upper surface of the chelipeds (fingers excepted) and first 2 pairs 

 of legs (dactyli excepted) is uniformly frosted with fine granules ... P. inarmatus. 



II. Eyestalks subcylindrical, reaching more than halfway along the 2nd 

 joint of the antennal peduncle : the antennal scale does not reach the 

 end of the antennal peduncle : the chelipeds and legs have some 

 transverse subsquamiform rugae, and the carpus of the chelipeds has 

 two longitudinal rows (including the inner border) of granules, but 

 their surface is not uniformly frosted ... ... ... P. limatulus. 



7. Pagurodes sp.? inarmatus, Henderson. 



Pagurodes inarmatus, Henderson, Challenger Anomara, p. 94, pi. x. fig. 5. 



A small female, which agrees completely with Henderson's description and 

 figure, and is, I think, this species, was dredged off the Travancore coast in 487 

 fathoms. The shell that it inhabited has not been preserved. 



The Challenger specimens were taken off Marion Island in the south-western 

 part of the Indian Ocean, and off New Zealand, but in a much greater depth.

8. Pagurodes sp. ? limatUlUS, Henderson. 



Pagurodes limatulus, Henderson, Challenger Anomura, p. 97, pi. x. fig. 6. 



Three small specimens which agree entirely with Henderson's description 

 and figure, and are almost certainly the same species, were dredged off the 

 Travancore coast in 430 fathoms. 



The Challenger specimens were taken to the south of the Philippines in 

 500 fathoms.

Body asymmetrical. Carapace most strongly calcified in front of the 

 cervical groove, and with the rostral projection conspicuous and often acute. 



Abdomen coiled in a spiral, the first two terga may be semicalcareous and 

 the last tergum and the telson are well calcified, but otherwise it is soft. The
