longer than broad and bearing 2 diagonal rows of setae on surface 

 and with distal margin thickly set with long setae, not more than 

 half as long as second joint, fourth joint unguiform, bearing 2 short 

 setae on concave margin and nearly as long as third joint. 



In male, first gnathopods with epimeron moderate, ventral margin 

 smooth, posterior margin provided with a spiniform tooth ventral 

 to which are 2 submarginal spines ; second joint rather long and 

 stout bearing a few long setae at distal end of anterior margin 

 which is slightly concave ; third joint about half as long as wide 

 with fascicle of setae on distal posterior angle ; fourth joint not as 

 wide as third, about twice as long as wide, more or less rectan- 

 gular with wrist articulating by anterior margin, the distal part of 

 which bears 4 large spines, and posterior margin elongated to form 

 a distal triangular lobe which bears 4 fascicles of setae ; wrist broader 

 than long, with posterior margin strongly convex so that segment 

 is broader than hand, posterior margin much shorter than anterior 

 and bearing several fascicles of setae ; hand oval, smaller than that 

 of second gnathopod, about twice as long as wide, with posterior 

 margin continuous with palm and bearing about 9 fascicles of long 

 flexible setae, palm oblique, and bearing 6 triangular processes which 

 are accompanied by submarginal teeth and fascicles of setae, pos- 

 terior margin very short ; finger long and stout, of usual form. 



Second gnathopods with epimeron higher than long with anterior 

 and -posterior margins parallel and with ventral margin slightly 

 convex and bearing a few short setae ; second joint longer than 

 that of first gnathopod ; third, fourth, and fifth joints as in first 

 gnathopod ; hand and finger more slender, but otherwise similar to 

 first gnathopod. 



Pereiopods slender, provided with dactyls; last pereiopods as 

 long as preceding ; epimera moderate, regularly convex ventrally. 



Postero-lateral margins of third abdominal segment not serrated. 



Uropods, 3 pairs, biramous ; first pair with long slender peduncle 

 provided with 5 or 6 spines on inner margin and one on apex, rami 

 also slender and styliform with inner one slightly longer than outer 

 one, extending as far as extremities of terminal uropods, rami 

 nearly as long as peduncle ; second uropods similar to first but with 

 peduncle much shorter and with rami more tapering than in first, 

 inner ramus rather stouter than outer and somewhat longer ; terminal 

 uropods extending well beyond telson, with rami subequal, laminar, 

 P/2 times as long as peduncle, both rami furnished with short setae 

 and plumose spines on inner margin and 1 or 2 on outer margin. 



Telson laminar, triangular, slender, cleft -/a to base. In one of
