Shell elongate-conic, thin, horn -colored with the outer edge of the 

 peristome marked by a dark chocolate line. Nuclear whorls 2.1, well 

 rounded, smooth except for exceedingly minute microscopic granu- 

 lations, which are apparent only under very high magnification. The 

 nuclear spire terminates rather bluntly. Postnuclear whorls moder- 

 ately well rounded, marked by fine incremental lines which might 

 be called obsolete, closely spaced, slender axial threads. Suture rather 

 strongly constricted ; periphery of the last whorl well rounded. Base 

 moderately long, narrowly umbilicated, well rounded and marked by 

 a continuation of the incremental sculpture referred to above. The 

 base is not thickened at the columella as it is in the Chinese species, 

 but remains comparatively slender. The last whorl is thickened into 

 a moderately strong callus behind the edge of the peristome. Aperture 

 broadly ovate; peristome slightly expanded and reflected. Parietal 

 wall adnate to the preceding turn. Operculum thin, horny, paucispiral, 

 consisting of 3.2 whorls with the nucleus excentric.
