Velutina. MOLLUSCA. TROCHUSIDjE. 327 



— This species differs from the genus Phasianella, in which Dr Turton has 

 placed it, by the absence of the lid ; and it differs likewise from the Velutina, 

 in the aperture being partly filled by the projection of the body-whorl ; in 

 the body-lip being incomplete retrally, and in possessing an imperfect pillar- 

 lip. In the absence of the lid, the size of the body-whorl, and wideness of 

 the aperture, it claims a place near Velutina, and should probably constitute 

 a new genus. — Stylina.
