as in Caucellus, almost at ric;ht angles with the merus, so that those of the 

 right side are closely applied to the convex outer border of the deflexed 

 hand. The legs are stout and beset with bristles : the dactyli end in sharp 

 black claws, the dactylus of the 3rd pair being as long as, that of the 2nd 

 pair being shorter than, its propodite. 



The male has 4 abdominal appendages on the right side. 



Colours in spirit : eyestalks, chelipeds and legs reddish yellow. 



Length of carapace of male nearly 12 millim : a female with eggs is 

 smaller. 



From Mr. Stanley Gardiner's Maldive collection (Hululu Male Atoll) ; not 

 in the Museum collection. 



This species seems to come nearest to E. hivtimanus White. In £. opet- 

 culatus Stimpson, from Florida, the right hand forms an operculum as in E. 

 janitor, but the two species do not seem to be alike otherwise. 



7. EuPAGURUs sp. 

 PaguTodts? inarmatus, Alcock (nec Henderson), Cat. Indian Deep Sea Crust., 1901, p. 225. 

 A small female specimen (No. ~f) from off C. Comorin, 4S7 fathoms (In- 

 vestigator ). It has a superficial resemblance to Pa^nrodes inarniatiis Hender- 

 son, but on comparing it with the types of that species in the British 

 Museum I find that the resemblance is only superficial, the gill-plates in the 

 "Investigator" species being not true trichobranchia; but merely narrow 

 phyllobranchicTe with the apex of each gill-plate bifid. 



Pylopaguropsis, n. gen. 



Carapace well calcified in front of the cervical groove, moderately 

 broadened posteriorly ; rostrum fairly prominent. 



Abdomen well developed, soft, spirally coiled, the last tergum and the 

 telson alone well calcified. 



Eyestalks moderately stout, of good length ; ophthalmic scales separated. 

 Antennal acicle well developed, flagellum long. 



External maxillipeds widely separated at base: the exopodites of ail three 

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

 has no trace of a flagellum. 



Chelipeds dissimilar and unequal, the right vastly the larger : the fingers 

 move in a vertical plane and have calcareous or minutely-corneous tips. 



Fourth pair of legs subcheliform, the 5th minutely cheliform : both pairs — 

 as also the urjpods — have the usual subterminal pavement of imbricating 

 granules.
