absence of the fine spiral striae, which may be due, as in the case of 

 some of the Indian specimens, to imperfect preservation. 



Stoliczka, from a comparison of specimens, identified M. glaher 

 (Muller)" from the Aachen Greensand, with M. radiatula, and this 

 identification is accepted by Holzapfel,f but not by Bohm.| 



Family NEEITID^. 



Genus NERITA, Linnasus. 



Neeita umzambiensis, sp. nov. 



Plate XXXVII., figs. 14, 15. 



DescrijHiou. — Shell thick, semi-ovate. Height less than the 

 greatest breadth of the last whorl. Spire very small, flat. Last 

 whorl very large, inflated, somewhat flattened posteriorly, rounded 

 anteriorly. Aperture nearly semicircular ; anterior margin rounded, 

 posterior more or less straightened, reaching to the level of the 

 spire. Inner lip smooth, moderately convex, with its margin 

 straight and rather coarsely denticulate. Outer lip thick, with its 

 inner margin crenulate. Surface of shell smooth, except for a few 

 indistinct growth-lines, and, in some cases, faint spiral ribs. 



Length 16 mm. ; breadth 21 mm. 



Bemarks. — This species, of which there are three specimens in the 

 Survey Collection, appears to be distinct from any of the Cretaceous 

 forms already described. § 



Neeita kafpeaeia, sp. nov.
