Description. — Body more or less soft. Carapace firmer, 

 slightly wider behind, then more or less moderately constricted 

 and hind edge moderately emarginated. Abdomen soft conic 

 spiral. Front of carapace broad, undulated as three wide lobes, 

 of which median little wider than each of slightly more advanced 

 lateral ones. Eyes conspicuous, a little broader than pedicels, and 

 reach slightly beyond articulation with outer joint of peduncle, 

 also basally pedicels still more constricted than at noticeable 

 median constriction. Antennules with broad basal joint in 

 peduncle, others all narrower and slender, third joint longest and 

 second joint shortest. Flagellum of antennule about long as sec- 

 ond joint, tapers rapidly to point, finely articulated, with series 

 of close-set long setae below and also slender accessory flagella. 

 Antennae extremely long, slender, longer than carapace or 

 chelipeds, and peduncle of three principal joints, of which basal 

 robust, second shortest and third longest, though latter extends 

 forward but slightly beyond peduncle of antennules. Flagellum 

 long, tapering, multiarticulate, and end filamentous. Buccal mass 

 fairly well developed, though not especially conspicuous. Man- 

 dibles firm, well developed. First and second maxillse subequal, 

 hairy, each wnth small palp. Maxillipeds well developed, second 

 twice length of first, and both pairs with long exopodites. Cheli- 

 peds moderately large, left larger, though right moderately de- 

 veloped, and both quite roughened with tubercles. Lower sur- 

 faces of both chelipeds more or less hairy. Left cheliped with 

 outer edge of propodus more keeled, comprising series of strong 

 tubercles. Tubercles on inner edge of left propodus and inner 

 edge of carpus largest. Carpus but little shorter than propodus. 

 Dactyls of chelipeds subequal. First and second pairs of legs sub-
