row of spinules or granules on the upper surface of the palm : the fingers are 

 longer than the palm : all these details are only visible after denudation. 



The 2nd and 3rd legs slightly surpass the larger cheliped : the edges of 

 their joints are setose, and the anterior edge of the carpus and propodite is 

 spinulose, though in the case of the 3rd pair of legs the spinules tend to wear 

 away : the dactylus is stout, curved, and as long as the two preceding joints 

 combined.

5. EUPAGURUS CARPOFORAMINATUS, n. Sp. 



This species is characterized by the presence on the under surface of the carpus of the 

 right, and usually also of the left, cheliped, in the adults of both sexes, of a pin-hole foramen 

 or gland. In other respects it resembles the Atlantic and Mediterranean E. prideauxn more 

 than any other species. 



Rostrum broad, rounded, not nearly so prominent as the well-pronounced 

 antennal angles of the carapace. 



Eyestalks about three-fourths the length of the anterior border of the 

 carapace, or a little more, but appearing much shorter by reason of their 

 piriform or grapestone shape, reaching to the distal third of the terminal 

 joint of the antennal peduncle ; eyes broadly reniform : ophthalmic scales 

 narrow-foliaceous, mucronate, dorsally concave. 



The antennal peduncle reaches to the middle of the terminal joint of 

 the antennular peduncle : antennal acicle curved, smooth, little setose, reach- 

 ing middle of terminal joint of peduncle : flagellum about thrice as long as 

 the carapace, nude. 



Chelipeds tomentose, but not so as to conceal surface sculpture. Right 

 cheliped rather slender, but much larger than the left, about 2^ times the 

 length of the carapace : the merus, which is about as long as the carpus, has 

 its under surface closely granulous, its upper aspect transversely rugulose, 

 and has a few spines on its distal border : the carpus, which is slightly longer 

 than the palm, has its upper border closely spinose and its outer surface 

 spinulose except in a well-defined longitudinal groove just outside of the 

 upper border ; sometimes a median longitudinal row of spines on the outer 

 surface of the carpus is enlarged ; near the middle of the under surface of the 

 carpus, tu the adult, is a deep pin-hole pit : the palm is longer than broad and not
