Specific Characters. Female. Body short and stout, bag-like, with the 

 head subquadrate in form and somewhat exerted, not being however distinctly 

 defined behind, rostral prominence short and obtuse at the tip. Trunk with 

 the dorsal face rather strongly vaulted and almost gibbously prominent in front, 

 seen dorsally, regularly oval or elliptical in outline. Eye wolly absent. An- 

 terior antennae about the length of the head, somewhat curved, and composed 

 of only 3 distinctly defined joints clothed with comparatively short, partly 

 spiniform setae, middle joint much the largest, terminal joint abruptly much 

 narrower and scarcely V 3 as l n g- Posterior antennae 3-articulate, with the 

 1st joint about the length of the other 2 combined, and provided near the 

 end anteriorly with a curved seta, the 2 outer joints firmly connected and 

 forming with the 1st one a geniculate bend; middle joint armed outside with 

 3 strong spines, the outermost being accompanied by a slender seta; term- 

 inal joint shorter than the middle one and armed on the transversely truncated 

 extremity with 3 unequal spines and a simple seta. Mandibles with the 

 masticatory part not much expanded, but divided at the end into several 

 sharply pointed teeth; palp quite rudimentary, being replaced by a single 

 slender seta. Maxillae with the masticatory lobe well developed and armed 

 with strong spines, palp undivided, with 2 coarse spines at the tip and 2 

 juxtaposed setae attached to a distinct ledge of the outer edge. Anterior 

 maxilllipeds composed of 3 joints, the 1st of which is rather large and broad, 

 being provided at the end inside with a narrow cylindrical lobe tipped with 

 2 slender spines; 2nd joint produced inside to a quite similar bispinose lobe, 

 3rd joint very small and armed with 3 spines. Posterior maxillipeds undivided, 

 lamellar, and fringed inside in its outer half with 4 spines, each terminating 

 in a blunt point. The 4 anterior pairs of legs of essentially same structure, 

 outer ramus somewhat larger than the inner one and having a short spine 

 outside the 1st joint, distal joint obliquely truncated and fringed at the end 

 with a row of 5 stout spines, inside which another row of somewhat more 

 slender spines is seen, the number of these spines varying in the different 

 legs; inner ramus in all the pairs provided at the end with 5 spines, one of 

 which is attached to the outer edge near the tip. Last pair of legs imperfectly 

 defined at the base, and armed at the narrowly exerted extremity with 4 short 

 spines. Between these latter legs a small triangular prominence occurs con-
