produced into strong and slightly divergent points. The left side is slightly more elongated 
than the right side (Plate LI, fig. 11). The points of the rostrum are moderately strong, but 
there is no trace of a rostral lens. 
_ The abdomen is composed of two segments. The combined length of the abdomen and 
furca is contained three and a half times in the total length of the cephalothorax, from the 
frontal margin to the base of the genital segment. The genital segment is quite asymmetrical. 
When viewed from above, the left side is seen to be expanded into a large wing-like projection 
with a pointed distal end. The dorso-lateral surface of the right side is furnished with a strong 
spine. The furcal joints are asymmetrical. The joint of the right side is longer and broader than 
the one ‘on the left side (Plate LI, fig. 11). 
The antennules are composed of twenty-four joints and extend to near the end of the 
last thoracic segment. 
The antennae, mandibles, maxillae and maxillipedes are similar to those of Pozdella princeps. 
The endopodite of the first pair of feet is three-jointed. 
The other three pairs of feet are of the usual Povtella type. 
The exopodites of the fifth pair of feet are asymmetrical. The left exopodite is consi- 
derably longer than the right. The exopodites are spiniform, and are drawn out to a single 
point at the apex. The left exopodite only is furnished with two outer edge spines. The endo- 
podites are asymmetrical and terminate in two spines of medium length (Plate LI, fig. 15). 
Male unknown. 
This species resembles Povzte/la danae in the two-jointed abdomen, the asymmetrical 
furcal joints, and in the shape of the exopodite of the fifth pair of feet. The large projection 
on the left side of the genital segment, and the asymmetrical condition of the fifth pair feet 
readily separate it, however, from that species. 
Occurrence. — Four specimens were found in the plankton collected at Station 117a.

Seen from above, the body appears elongate ovate, and rather narrow. The cephalic 
segment is furnished with side hooks, and a pair of dorsal eye-lenses. The last thoracic segment 
is symmetrical. The posterio-lateral angles are narrowly rounded, and are only very slightly 
produced (Plate LII, fig. 1). The points of the rostrum are moderately strong, and there is a

furca is contained three and one-third times in the total length of the cephalothorax, from the 
frontal margin to the base of the genital segment. The genital segment is asymmetrical. The 
proximal portion of the lateral margin of the left side is produced into a large spiniform process 
(Plate LI, fig. 1). The fureal joints are asymmetrical. The left furcal joint is distinctly broader 
than the right. 
The antennules are twenty-two-jointed and reach to the end of the third thoracic segment.
