Shell of medium size, ovate, thin, semitranslucent, pale horn- 

 colored with the peristome bounded by a very narrow zone of choco- 

 late brown ; interior of aperture a little paler than the outside. Part 

 of the nuclear spire is decollated, the portion remaining so cleverly 

 plugged that one might be misled into taking it for the apex of the 

 nucleus. The remaining turn is marked by fine granulations apparent 

 only under high magnification. Postnuclear whorls strongly inflated, 

 well rounded, marked by slender, depressed, threadlike incremental 

 lines which are about as wide as the spaces that separate them, and 

 microscopic spiral striations. Suture strongly constricted ; periphery 

 and base of the last whorl decidedly inflated and strongly rounded. 

 The latter is marked like the spire. The base is narrowly umbilicated. 

 Aperture oblique, oval with the peristome slightly expanded and 

 appressed and adnate to the preceding turn at the parietal wall.
