 parent, obsoletely striate. Whorls 6, convex, the last is much 

 larger than the others. Aperture ovoid; columella bearing 

 a decurrent lamella, which disappears within the aperture. 

 The truncation forms a strong projection into the aperture 

 by reason of the inflection of the columellar margin. Peri-

 diam. 6 to 7 mm. (P. et if.)-
