throughout; ( 'ephalic ^egment scarcely longer than the 3 succeeding segments 

 (.nmbined: rostrum very long and evenly curved. Urosome nearly as long as the 

 anterior division, and tiijiering only very slightly behind, last segment about the 

 length of the preceding one. and having the anal opeivle finely spimilose. Caudal 

 rami quadrate in 1'oriu and slightly instrictcd at the base, each having, somewhat 

 beyond the middle of the outer edge, a notch carrying a slender seta and a short 

 spine, middle apical sctte of moderate length. Anterior antennas comparatively 

 short and gradually attenuated distally, 8-artieulate, 1st joint much the largest, 

 terminal part not attaining half the length of the proximal. Posterior antenna,' 

 comparatively less robust than in the '2 preceding species, outer ramus very nar- 

 row, with the middle joint extremely m : -iute and without any seta. 1st pair of 

 legs rather slender, outer ramus considerably exceeding half the length of the 

 inner, middle joint much the longest, terminal joint small, with only 3 claw-like 

 spines and a slender seta at the inner corner; inner ramus with the 2 outer joints 

 very short and suh"i|ual. apical claws rather unequal, the outer one being scarcely 

 half as long as the inner and nearly straight. Last pair of legs with the distal 

 joint large, oval in form, carrying 6 rather unequal setse, 4 of which issue from 

 the somewhat exserted and obliquely-truncated extremity; inner expansion of 

 proximal joint comparatively short, triangular, not nearly extending to the middle 

 of the distal joint, marginal seta. 1 5 in number, the outermost one very small. 

 Ovisacs rather short, extending, as a rule, only slightly beyond the middle of 

 the urosome. 



Mulr of still more slender form than female. Anterior antenna' consider- 

 ably more elongated, and transformed in the usual manner. Spine attached to 

 the inner corner of the 2nd basal joint in the 1st pair of legs falciform, incurved 

 and obliquely cut of! at the tip. Inner ramus of 2nd pair of legs with the distal 

 spiniforni appendage of the outer edge peculiarly transformed, terminating in a 

 bro:id ^ecuriform lamella, apical spine replaced by an ordinary plumose seta. 

 La-t pair of legs very small, distal joint cordate in shape, with only 4 marginal 

 BetSB, the outermost but one very -mall, hair-like; inner expansion of proximal 

 joint very >light, with only 2 unequal seta 1 . 



I'.ody of a liiiht yellowish colour with some of the segments bordered \\ith
