Specific Characters. Female. Body very slender and elongated, of per- 

 fectly cylindrical form. Cephalic segment nearly as long as the 3 succeeding 

 segments combined, and forming in front a short and broad rostral prominence 

 of triangular form. Epimeral plates of the 3 succeeding segments very small, 

 but distinct; 5th segment fully as large as the preceding one. Urosome about 

 the length of the anterior division and rather massive, with all the segments 

 perfectly smooth ; last segment much smaller than the other 3, and deeply incised 

 behind in the middle. Caudal rami very small, slightly longer than they are 

 broad, and each carrying outside, about in the middle, 2 unequal bristles, dorsal 

 seta issuing close to the end, apical seta accompanied outside by a thin bristle 

 and having its proximal half very coarse, almost spiniform, distal part however 

 extremely thin, hair-like and generally extended obliquely outwards. Eye wholly 

 absent. Anterior antennae nearly as long as the cephalic segment, and composed 

 of 9 well-defined joints clothed with moderately long setae, 1st joint comparatively 

 short and thick, 2nd much the largest and slightly attenuated distally, 3rd joint 

 about twice the length of the 4th, which carries at the end the usual sensory 

 filament, terminal part scarcely longer than those 2 joints combined. Posterior 

 antennae with the outer ramus very fully developed and composed of 4 well- 

 defined joints, the 1st about equal in length to the other 3 combined. Mandibles 

 with the masticatory part abruptly incurved and somewhat flattened, cutting edge 

 divided into several strong teeth, palp large, with the outer ramus distinctly 

 4-articulate. 1st pair of legs with the outer ramus slightly longer than the inner, 

 middle joint without any seta inside, terminal joint armed with 4 spines and 

 inside the tip with a slender seta; inner ramus with the 1st joint about the length 

 of the other 2 combined and without any seta inside, middle joint setiferous, 

 terminal joint about the size of the middle one, and carrying on the tip 3 une- 

 qual setae, the middle one very long. The 2 succeeding pairs of legs with the 

 outer ramus very narrow and without any seta3 inside, terminal joint only slightly 

 longer than the middle one, and provided at the end with 3 slender spines and 

 a still more slender seta; inner ramus a little shorter than the outer, and having
