Several small specimens from the Maldives. 



Distribution. Japanese and Chinese Seas, to 1'6 ftxthoms : Seas of the East Indian Archi- 

 pelago, to 49 fathoms: Bay of Bengal, to 30 fathoms: Maldives. 



The adult animal seems to love light shells like those of Pirula. 



Anapugurus, Henderson. 



21. Anapagurus, sp. 



A small specimen viinus most of its appendages, from the Maldive Is., is perhaps referable 

 to this genus. 



Catapagnrus, A. M.-Edw. 



22. Catapagurus ensifer, Henderson, Trans. Linn. Soc. Zool. (2) v. 1893, p. 424, PI. XXXVIII. 

 figs. 16—19. 



Numerous specimens, males and egg-laden females, from the Maldives. Some with a 

 commensal sea-anemone. 



Distribution. Gulf of Martaban, Maldives. 



Cestopagurus, Bouvier. 



23. Cestopagurus olfaciens, n. sp. 



Rostrum fairly prominent. Eyestalks longer than the anterior border of the carapace and 

 than the antennal peduncles, but much shorter than the antennular peduncles. These last are 

 particularly long and stout, their terminal joint is club-shaped, and their upper flagellum is 

 divided into about 9 segments (not including the terminal filament), each of which carries a 

 bunch of hairs that is longer and more conspicuous than the lower flagellum. 



The right cheliped is very much larger than the left, and is smooth and almost bare: the 

 hand is the biggest joint, and the palm is longer than broad, and broader at its far end 

 than at its near end. 



The 2nd and 3rd legs are smooth and bare, the dactyli being long and very slender. 



The right vas deferens passes from the coxa of the 5th right leg across the ventral surface 

 of the abdomen, and then ascends obliquely over the left flank : it increases slightly in calibre 

 distally, and ends abruptly. 



The length of a carapace of a male is 3 mm., of an egg-laden female 2 mm. In two males 

 the left gill-chamber is greatly distended by a parasite. 



N. Male Atoll, Maldive Is. Several specimens, in tiny shells of various kinds, chiefly long 

 turret-shells. 



This species differs from C. coutieri in its very long antennules, its remarkably long and 

 stout olfactory hairs, its smooth and bare chelipeds, its abruptly-ending vas deferens, and its 

 long and slender dactyli of the 2nd and 3rd legs.
