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 setie ; 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 in 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 

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

 Ultimate caudal stylets projecting a little beyond the preceding pairs ; 

 rami short, broad, and with spiuous 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 lllm .

MELITA NITIDA Smith, sp. uov. (p. 314.) 



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; flagelluni 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 au- 

 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 

 tached in a notch in the middle of the extremity of the propodus, not 

 closing upon the extremity of the propodus but projecting inward* 

 Second pair of legs stout; carpus short, triangular; propodus some, 

 what oval, the palmary margin oblique, arcuate, continuous with the 

 posterior margin, and armed with a series of minute spines and with 

 numerous stiff hairs, the clothing of hairs continuing round upon the 

 posterior margin to the carpus; dactylus curved, tip resting within the 

 palmary margin. Third pair of legs slightly longer than 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. 

 Penultimate caudal stylets not quite reaching the tip of the preceding
