Hypsophrys longipes, Alcock and Anderson, Ann. Hag. Nat. Hist., Jan. 1899, p. 6 : Alcock, Investigator Deep 

 Sea Brachyura, p. 15, pi. i., fig. 1 : J. A. S. B., LXVIII., pt. 2, 1899, p. 164. 



Rostrum deeply bifid. Linea anomurica distinct. 



Four large spines on tlie anterior border of tlie carapace — two close 

 together at the base of the rostrum, one at cither orbital angle. 



Lateral borders of dorsum of carapace well defined, spinulate ; the ridge 

 on the side-wall of the carapace that defines the branchial regions anteriorly is 

 also spinulate. A row of spines on the hepatic region, the largest of which is 

 on the lateral border of the carapace and has a spine dorsad of it. 



Gastric region obscurely subdivided, each lateral subregion is armed with 5 

 or 6 large spines, while on the median region there is a central spine sometimes 

 followed by a row of spinules. Subhepatic and suborbital region with numerous 

 large spines, one of which is " antennal." 



Eyes well pigmented. Antennal flagella more than twice the length of the 

 carapace. 



Rows of spinules on the exposed surface of the ischium merus and exopo- 

 dite of the external maxillipeds, and a row on the basal joint of the antennules. 



Chelipeds slender, reaching not far beyond the end of the carpus of the 

 first pair of ambulatory legs, the arm and wrist not stouter than the meropodites 

 of the first 3 pair of legs ; spinate and spinulate as in the preceding species ; 

 fingers as long as the hand. 



The second and third pair of legs, which are slightly longer than the first 

 and three times as long as the fourth, are four times the length of the carapace. 

 In the first three pair of legs the merus is compressed and has its anterior 

 border spinate and its posterior borders spinulate, the jiosterior border of the 

 propodite carries a few distant articulating spinelets, and the dactylus — which 

 is about two-thirds the length of the preceding joint — has a close comb of arti- 

 culating spines along its posterior border. 



The fourth (dorsal) pair, which are extremely slender, have the posterior 

 border of the merus strongly spinate : the propodite is several times longer 

 than the minute dactylus. 



The terminal joint of the male abdomen ends acutely. 



Hairs and bristles are sparsely present just as in the preceding species. 



The carapace of a large egg-laden female is 38 millim. long and 30 millim. 



broad.
