 t| M . tvp.- species ami more evenh attenuated behind. Cephalic segment large, 

 attaining :ili.ut the length of the -1 succeeding segments combined, rostral plate,

 narrouer and more produced than in that species, exceeding in length the anal

 , aliated in it- pr..\imal half, apical seta' normal. Antenna' and oral parts about 

 in A', minuta. 1-t pair of legs likewise of a very similar structure, though 

 having the terminal joint of the outer ramiis comparatively shorter, scarcely longer 

 than the middle joint. Natatory legs scarcely different from those in the type

Remarks. The present form is closely allied to N. tn/nn>'i. but is of 

 smaller size, and moreover dilVer- conspicuously in the shape of the rostral plate 

 ;(ii.l in the much narrower and more produced caudal raiui.

Specific Characters. I^nnili. i;dy on the whole more strongly built 

 than in the ~2 piecnling species, though of 8 very similar appearance. Kostral 

 plat.' very prominent, terminating in a sharp mucroniform point. Last caudal 

 incut much shorter than the preceding one. anal opeide prominent, semi- 

 lunar. and i-oar>'-!y denticulate. Caudal raiui about twice as long as they are 

 broad, and exhibit ini: dor-ally a well-marked longitudinal keel, middle apical seta 

 liir_'l\ -tioiiL'. spinil'orm. not jointed at the base. Antenna', oral parts and 1st 

 p:iir of b-g- \.-r\ ximilar to tho-c apjiendage- in the ~2 preceding specie-. Natatory 

 legs c,,mp;irati\el\ larger. La-t pair of legs likewise more fully developed, with 

 the inner rxpan-ion of proximal joint more produced, extending almost R8 far 88
