its systematic position next Oregonia and its placement by him in the 

 more primitive macrocheiroid section of the subfamily Inachinae. It is 

 not, however, the first illustration of the gonopods of Eurypodius 

 latreillei, which were described and figured by Brocchi (1875, p. 90, 

 figs. 177, 178).

Type: Male holotype, in British Museum, length including rostrum 

 30 mm, width 15 mm. 



Type locality: Lat. 50° 08' 30" S, Long. 74° 41' 00" W, 175 

 fathoms, Challenger station 308. The designation "off the coast of 

 Chiloe" (Miers, 1886) is in error, due to confusion of Challenger 

 station 308 with 303. (Cf. Murray, 1895, pp. 1138, 1149). 



Localities subsequently reported: None. Known only from the type 

 locality above, correctly described as Tom Bay, east coast of Madre de 

 Dios Island, Wide Channel, Magallanes, Chile. 



Atlantic analogue: None. A Subantarctic, abyssal species. 



Diagnosis: Rostrum sharply inclined, spines laterally divergent. A 

 small spine on upper margin of orbit in addition to postocular spine. 

 Interantennular spine prominent, deflexed. Ambulatory legs slender. 

 Otherwise as in Eurypodius latreillei. 



Description: Rostrum of the male remarkably reflexed, bent upward 

 at an angle of nearly 45° to the front, with the spines toward their 

 apices laterally divergent from one another. Body and limbs thinly 

 pubescent, carapace narrow in proportion to its length, with spines 

 disposed as commonly in specimens of Eurypodius latreillei of the same 

 size and sex, e. g., two upon the gastric, one upon the cardiac, one on 

 each branchial region and one on the posterior margin, besides some 

 smaller granules on the sides of the hepatic and branchial regions. A 

 small spine on upper margin of the orbit, besides the postocular spine. 

 Spines of the rostrum considerably exceeding half the length of the 

 carapace, contiguous at the base, but in the distal third of their length 

 curving laterally and outward ; a strong spine on the interantennulary 

 septum. Eyes, antennae, and maxillipeds of the same form as in 

 Eurypodius latreillei. Chelipeds with palms not turgid, as in young 

 males of the typical variety (a) of that species, but compressed, fingers
