Specific Characters. Female. Body elongated, with all the segments very 

 sharply marked off from each other by deep instructions. Cephalic segment, seen 

 dorsally, almost quadrangular in form, dorsal face produced behind into a strong 

 backwards-curving spiniform projection. Rostrum strongly prominent, conspicuously 

 constricted at the base, and exhibiting on each side in the middle an angular 

 ledge carrying a delicate bristle, terminal part linguiform, with the tip narrowly 

 rounded. The 4 succeeding segments angularly produced laterally, and each car- 

 rying dorsally 2 juxtaposed strong denticulated spines curving backwards; hind 

 edge of the segments coarsely spinulose, except between the 2 dorsal spines. 

 Urosome almost as long as the anterior division, the 2 divisions of the genital 

 segment and the succeeding segment each with 2 dorsal spines similar to those 

 on the anterior division, but more closely juxtaposed; lateral parts of these seg- 

 ments triangularly expanded and densely setiferous. Penultimate segment with 

 the posterior edge divided dorsally in the middle into 4 peculiar spines, branching 

 in a hand-like manner; last segment simple and shorter than the preceding one. 

 Caudal rami rather produced, considerably longer tban the- anal segment, and 

 each carrying a very strong, almost spiniform apical seta exceeding in length the 

 urosome, the other setae small and hair-like. Anterior antennas rather slender, 

 exceeding in length the cephalic segment (without the rostrum), and 6-articulate, 

 2nd joint the largest, and provided at the hind edge beyond the middle with a 

 small nodiform projection, 3rd joint exceeding in length the outer 3 joints com- 

 bined. Posterior antennas strongly developed, being fully as long as the anterior 

 ones, outer ramus of normal structure. Posterior maxillipeds comparatively large, 

 with the basal part narrow, hand fusiform in shape, dactylus much elongated and 

 curved at the end. 1st pair of legs slender and elongated, with the 2nd basal 

 joint very narrow, crater ramus small and only consisting of 2 joints; inner ramus 

 with the proximal joint quite smooth, and somewhat exceeding in length the 2nd, 

 basal joint, apical claw long and slender. Natatory legs with both rami very 

 narrow, distal joint of inner ramus provided in the 2nd and 4th pairs with 3, in 

 the 3rd pair with 4 setae, none of which issue from the outer edge. Last pair 

 of legs of moderate size, distal joint however very small and somewhat obliquely 

 truncated at the end, with only 3 setae; inner expansion of proximal joint rather
