Localities subsequently reported, with collectors: Chile: Chiloe, 45 

 fathoms, Challenger (Miers, 1886; Murray) ; Porto [Puerto] San 

 Pedro, depth not given, Hassler (Rathbun, 1925) ; Bahia de Concep- 

 tion, near Talcahuano (Porter, 1936a). The remaining localities are 

 Atlantic. 



Diagnosis: Not more than two lateral marginal spines, the branchial 

 always the stronger. Chelipeds of old males massive, but not exceeding 

 length of first ambulatory legs. Rostrum bifurcate for less than half its 

 length. Branchial spine less than half as long as width of branchial 

 region. Apex of male first pleopod flaring, tip bluntly pointed ; opening 

 expansive, protected above by a suberect lobe. 



Description : Spines and tubercles of carapace very unequal ; the prin- 

 cipal spines proportionally much longer in the young than in the old. 

 Gastric tubercles seven, three median, the middle one sometimes almost 

 disappearing, and two on each side in a longitudinal line ; a long cardiac 

 spine, a longer intestinal spine, a still longer spine on the lateral margin 

 at the widest part of the carapace and opposite the narrow anterior bor- 

 der of the cardiac region. Hepatic margin produced in a spine. A curved 

 line of tubercles following the innermost margin of the branchial region ; 

 among the larger tubercles of this region a triangle of three near the 

 gastric region prominent; a still larger spine lying above the postero- 

 lateral margin and in a line with the cardiac spine; from it a row of
