smooth, nearly flat, depressed below the level of the outer lip ; with 

 its inner margin rather coarsely denticulate. 



Length 16 mm. ; breadth 23 mm. 



Bemarks. — This species is known by a single specimen, in which 

 the colour-bands are still fairly well preserved. It differs from N. 

 umzamhiensis in the posterior part of the last whorl being more 

 flattened, whilst the anterior part is produced and less rounded ; 

 also the inner lip is nearly flat and the outer lip is thin at the margin.

Description. — Shell turreted, consisting of eleven rather high 

 whorls. Spire very long, acute. Sutures rather deep. Whorls 

 near the apex are slightly convex. In the remaining whorls the 

 greatest convexity is at the junction of the anterior third with the 

 posterior two-thirds, the posterior part being flattened and the an- 

 terior part curving gradually to the suture. Base of last whorl 

 rounded. Aperture ovate, angular posterioi-ly ; inner lip thick. 



Whorls near the apex ornamented with rather strong, rounded, 

 concave, transverse ribs, with very fine ribs between them ; also with 

 small spiral ribs. The remaining whorls are ornamented with 

 growth-ridges or lines which are indented so as to form a rounded 

 angle at about the middle of the whorl. 



Length 95 mm. ; breadth 39 mm. 



Affinities. — Griesbach regarded this species as identical with P. 

 undosa (Forbes),-'' from the Trichinopoli Group. But it is distin- 

 guished from the latter by its smaller apical angle, relatively higher 

 whorls, and much less distinct transverse ornamentation. 



Griesbach also regarded Turritella Mcadi, Baily, as a young indi-
