scale-like, subovate, outer ramus acute, single-jointed, and scarcely twice the length of peduncle; telson 

 small and cleft to a little beyond the middle. 



Length, [2 mm. Type No. 29240, U. S. Nat. Mus. 



Described from a single specimen taken b) S. D. Judd, at Newport, R. I. 



This species differs from most of the species of Welita in having smaller second gnathopods, smaller 

 terminal uropods, and more elongated propodi on the peraeopods, but possesses uo characters which 

 exclude it from the genus. 



Elasmopus laevis (Smith).

Eyes nearly round; first antennae rather stout and about two-thirds the length of body; third joint 

 of peduncle about two-thirds the length of second, which is subequal to the first; flagellum about as 

 long as peduncle, segments rather short; secondary flagellum not half as long as last joint of peduncle 

 and consisting of two oblong joints and a minute very short terminal joint; second antennae scarcely 

 longer than ~>eduncle of first pair and slender, flagellum shorter than peduncle and consisting of about

eight joints. First four coxal plates not deeper than their segments; fourth about as broad as deep. 

 First gnathopods in male with hand oblong, subequal to carpus; palm quite oblique and evenly convex. 

 Second gnathopods of male very large, car] >us scarcely one-fourth the length of hand; much broader 

 than long, with a narrow posterior lobe; hand oblong, the opposite sides nearly parallel, palm oblique, 

 smooth; a row of four or five spines near base of finger on a ridge just, within margin of palm; the 

 stout finger closes not against palm but into an excavation on inner side of hand: a conical tooth at 

 upper end of this excavation. Hand in first gnathopods of female much like that of the male, but the 

 palm nearly transverse. Second gnathopods much smaller than iti the male, oblong in shape, some- 

 what resembling first gnathopods of the male; palm oblique, armed with two rows of spines along its 

 entire length and with a pair of larger spines at distal end; finger more nearly straight than in the 

 male; more evenly tapering and closing against the palm. Merus and carpus much expanded in last 

 two peraeopods of male; terminal uropods projecting beyond others, rami short, broad, inner one 

 narrower than outer and a little shorter, with a small spine near base of inner margin: outer ramus 

 with three fascicles of stout spines on outer margin; tips of both rami truncated and armed with 

 numerous spines; telson with lobes oblong, notched at the tip, where there is one or two spines.
