Plate 80, Figures 5-7 



Raninoides ecuadorensis Rathbun, Proc. Biol. Soc. Washington, vol. 48, p. 1, 

 1935 (type locality, La Plata Island, Ecuador; type, U.S.N. M. no. 69319). 



Diagnosis. — Anterior end of carapace roughly granulate. Three 

 spines (rarely four) on lower margin of manus. No spine on merus. 



Description. — Carapace widest at middle, tapering toward either 

 end; finely and closely granulate across the front which is irregularly 

 roughened. Anterolateral spine inclined slightly outward, the tip 

 curving inward. Rostrum with two longitudinal fm-rows, a slender 

 median tooth and a short lateral tooth directed forward. Outside the 

 rostrum the adjacent angle is nearly a right angle, and is followed by 

 a short tooth with convex sides and a short terminal point. Outer 

 orbital tooth slender, curved, and reaching nearly as far forward as the 

 tips of the lateral teeth of the rostrum. Merus of cheliped unarmed, 

 carpus somewhat flattened above, each upper margin terminating 

 distally in a minute tooth. Manus short, upper surface with two thin, 

 parallel, erect rims, lower edge with three long slender spines (four 

 in one of the largest specimens). No spine on movable finger; five 

 on inner edge of fixed finger. The dactyls of the first three legs are 

 crescentic, of the first leg short and broad and slightly hollowed out, 

 of the second and third legs longer, narrower, and more crescentic, the 

 second acutely pointed, the third bluntly tipped. The narrow fourth 

 leg reaches only to middle of carpus of third leg; its dactyl is suboval. 



Measurements. — Length of male 20.1, width 11.6 mm. 



Type locality. — Ecuador: La Plata Island; 45-55 fathoms; sand, 

 shale, rock; February 10, 1934; station 212, Hancock Galapagos 

 Expedition; type specimen, male (69319); 50 specimens (69320).
