Genus PSEUDOVARICIA, Tate. 



[Trans. Eoy. Soc. South Aust. vol. s. 1888, p. 146.] 



The following description of this interesting genus is given 

 by its author: — "Shell cylindroid-fusiform, smooth, spire obtuse, 

 wliorls with a few remote and non-continuous imbricating varices ; 

 canal very short, wide, columella smooth, slightly arched. The 

 varices are not produced as ordinarily by an outward thickening 

 or bulging of the shell wall, but appear as abrupt step-like 

 interruptions to the regularity of the spiral curve, and seem to 

 indicate that each periodic mouth was slightly margined with 

 enamel, and the new growth to have been commenced from 

 within, so that the successive growths are not in the same plane."
