Specific- Characters. Female. Anterior division of body but very slightly 

 vaulted above, seen dorsally, oblong in form, greatest width equalling about l /$ of 

 the length, and occurring about in the middle, anterior extremity rather broad 

 and triangularly pointed at the tip, posterior gradually somewhat attenuated. 

 Cephalosome about the length of the 3 succeeding segments combined, and some- 

 what depressed in its anterior part, lateral edges forming on each side, somewhat 

 in front of the middle, a well-marked hook-like projection, rostrum abruptly 

 detiexed, with the rami rather strong and acutely pointed. First segment of 

 metasome considerably larger than the succeeding ones, last segment compara- 

 tively small, with the lateral lobes of moderate size and triangularly pointed. 

 Urosome considerably exceeding half the length of the anterior division, and 

 somewhat asymmetrical, being generally turned out of the axis of the body to 

 the right, genital segment somewhat tumefied in the middle and produced ven- 

 trally on right side to a narrow rod-like projection. Caudal rami conspicuously 

 unequal, left ramus constricted at the base and gradually widening distally, right 

 considerably larger and more exstant, with the outermost seta quite short, both 

 rami very finely ciliated inside. Ventral eye comparatively small, though distinctly 

 protuberant, dorsal eyes well developed, corneal lenses placed at some distance 

 from them, near the lateral edges. Anterior antennae, when reflexecl, reaching 

 about to the end of the 3rd pedigerous segment, being generally extended 

 obliquely anteriorly in the living animal, proximal part somewhat dilated, distal 

 part rather slender. Posterior antenme with the inner ramus rather fully devel- 

 oped, outer, on the other hand, very small, scarcely exceeding in length the 

 proximal joint of the inner, and much narrower. Natatory legs with the apical 

 spine of the outer ramus rather slender and coarsely dentate outside. Last pair 

 of legs with the outer ramus narrow and elongated, about twice the length of the 

 basal part, proximal joint linear in form, with 2 small spines outside, and produced 

 at the tip inside to a slender spiniform process, distal joint rather small, carrying 

 3 spines on the tip, the innermost much the largest and finely denticulate inside; 

 inner ramus very small, and produced at the end to 2 subequal diverging denticles.
