longer than broad, the posterior margin straight and furnished with fas- 

 cicles of stout hairs; palmary margin nearly transverse, slightly arcuate, 

 and armed with short setse; dactylus slender and fitting closely the pal- 

 mary margin. Legs of the second pair larger; carpus short, as broad 

 as the base of the propodus, the posterior angle thickly clothed with 

 stout hairs ; propodus iu the male stout, broadest distally, the palmary 

 margin expanded toward the inferior angle and excavated on the inner 

 side to receive the long and strongly curved dactylus; in the female, 

 elongated, slightly narrowed distally, the posterior margin continuous 

 and nearly parallel with the palmary, and furnished with fascicles of 

 stout hairs. Fifth pair of legs but little longer than the third or fourth ; 

 sixth and seventh much longer than the fifth, subequal, stout, their 

 raeral and carpal segments considerably expanded, especially in the male. 

 Ultimate caudal stylets projecting a little beyond the preceding pairs ; 

 rami short, broad, and with spinous tips ; the outer ramus slightly longer 

 and broader than the inner, and its outer margin armed with a very few 

 fascicles of spinules. Telson reaching to the bases of the rami of the 

 posterior caudal stylets, nearly as broad as long, and cleft two-thirds of 

 the way>to the base. 



Length, 5-7 mm .

Eyes small, round, black. Antennula about two-thirds as long as 

 the body ; first segment of the peduncle slightly shorter than the second, 

 which is nearly twice as long as the last; flagellum longer than the pe- 

 duncle. Antenna shorter than the antennula, but the peduncle consid- 

 erably longer than the peduncle of the antennula, the penultimate seg- 

 ment being scarcely shorter than the penultimate segment of the an- 

 tennula, while the ultimate segment is subequal with it. First pair of 

 legs with the carpus longer and broader than the propodus; propodus 

 oblong, slightly curved ; dactylus very small but stout, curved, and at-

 palmary margin. Third pair of legs slightly longer thau the fourth. 

 Three posterior pairs slender, the fifth somewhat shorter than the sixth 

 and seventh, which are subequal, and have the anterior margins of the 

 bases armed with small spines and the posterior margins minutely ser-. 

 rate. None. of the dorsal margins of the segments of the abdomen ser- 

 rate or emarginate, but the margin of the fifth segment armed with 

 several slender spines on each side near the median line of the dorsum.
