25. Neritina (Vitta) pulcherrima, n. sp. (Plate I. fig. 25). 



Shell small, ovate, smooth, shining, generally pale grey, more or

Hab. Dredged near the " Sow and Pigs" reef, Port Jackson. 



A very prettily painted little species of a more rounded form than 

 N. viridis, Linn., and easily distinguished by its peculiar style of 

 ornamentation.

Shell rather solid, depressedly orbicular, pale brown, encircled by 

 three prominent ribs, and longitudinally finely distantly plicate, the

 spire with the apex acute, exserted ; umbilicus moderate, encircled 

 by a rib similar to those on the body-whorl and decussated by 

 concentric radiating striae within ; aperture circular ; outer lip a 

 little thickened ; peritreme continuous.

A species of an ivory-white throughout, in form not unlike B.
