This species is much narrower than U. menkeana, and punc-

 but it is smoother, with the peristome adnate above.

Shell subcylindric, the upper third or fourth tapering to 

 a narrow truncation, terminal plug long and tongue-like. 

 Surface glossy, almost smooth, except the latter part of the 

 last whorl, the basal keel and the first whorl or two, which are 

 striate. Color broivn or corneous-brown and ivliite, in alter- 

 nate stripes, more or less irregular. Whorls 8 to 10, almost 

 flat, the last having a cord-like keel beneath, not free in front. 

 Aperture rounded, brown in the throat; peristome white, ex- 

 panded and reflexed, adnate above for a short distance. In-
