Cornea slightly swollen, occupying slightly less than half of extensor surface of eyestalk. Chelipeds usually somewhat dissimilar and distinctly unequal in both sexes (atypically subequal in figured specimen); fingers of major chela slightly longer than palm, spinose on extensor margin. Second, third,. Figure 75.—Ucides cordatus, male (carapace length mm) from Dominica station 112. and fourth pereiopods of males bearing very long silky hairs, especially numerous on flexor margins of carpus and propodus and on extensor margins of carpus and propodus of third and fourth pereiopods; walking legs of females without conspicuous hairs. Fringe of hairs on opposable surfaces of coxae of third and fourth pereiopods reduced, no more prominent than hauiness between coxae of second and third pereiopods. Denuded first pleopod of male terminating, in posterior view, in somewhat truncate tip inclined slightly mesially, with narrow chitinous process on lateral surface proximal to tip (fig. 76a). A large species, maximum carapace length in midline about 70 mm. Color in life.—Carapace mostly grayish blue with posterolateral portions of branchial region white; fronto-orbital region margined with dark orange; anterior projection of mesogastric region with single purple spot and pair of them in lateral protogastric regions;.
