In the female there is a pair of small curved rod-like appendages on 

 the first abdominal segment. 



Length of carapace of male about 8 millim., a female is smaller 

 Colours in spirit, faint pinkish or very pale lilac.

— — . Off Travancore coast, 430 fath. " Investigator." 



The "Challenger" type specimen, with which the "Investigator" 

 specimens have been actually compared, came from south of the Philippines 

 in 500 fathoms. 



The damaged female specimen which in my Catalogue of Indian Deep- 

 Sea Crustacea (p. 225) I referred with doubt to Pagurodes inannatus Hender- 

 son, is, I find, on comparison with the " Challenger " types, not that species, 

 although it has a strong resemblance to it. In fact, the " Investigator " 

 specimen is not a Pagurodes at all, since its gills are not trichobranchije, but 

 merely narrow phyllobranchise with the apex of each gill-plate expanded and 

 bifid.

Carapace elongate, broadened posteriorly, well calcified in front of the 

 cervical groove. Rostrum broad and indistinct. Abdomen well developed, 

 soft, spirally coiled. 



Eyestalks stout : ophthalmic scales small, distant. Antennal acicle long : 

 flagellum long, nude ^i sparsely setose. 



External maxillipeds widely separated at base : the exopodites of all 

 three pairs of maxillipeds are flagellate. The endopodite (palp) of the ist 

 maxillae is non-flagellate.* 



The chelipeds, though nearly alike in form and sculpture and very little 

 unequal in length, are unequal in bulk, the right being the larger: the fingers 

 move in a horizontal plane and the finger-tips are corneous. 



The 4th pair of legs are subcheliform and the 5th pair minutely 

 cheliform : in both (as also on the uropods) there is the usual subterminal 

 rasp of imbricating corneous granules. 



In the male the vas deferens of the right side protrudes as a long tube 

 ending in a long tapering filament, and that of the left side as a short conical 

 tube or papilla. 



* .My material is so scanty that I have only ventured to detach the Ist maxillx of one specimen, where 

 find the flagellum of the palp to be represented by a minute papilla.
