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 sete; 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 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 Jong, and cleft two-thirds of 
the way to the base. |

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- 
dunele. 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 subequai 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
