Similar to U. sauvalleana, but less narrow, and there is no 

 band above the suture, and the surface is very finely though 

 shallowly striate, while in sauvalleana it is smooth. The 

 deciduous portion of the spire is very short and not espe- 

 cially attenuate (fig. 15) ; in this the species of this group 

 resemble Pycnoplychia, and are unlike typical Gongylostoma.

Shell shortly rimate, cylindric, the upper third or half 

 slowly tapering to the narrow truncation, or retaining the 

 spire complete; thin; surface smooth and glossy, "opaline 

 flesh-colored," with a narrow brown or reddish band or line 

 above the suture. Whorls slightly convex, the last not free, 

 rounded beneath, its latter half finely striate; girt below the 

 middle with a narrow purplish-brown band. Suture slightly 

 crenulate. Aperture irregularly oval, slightly oblique, the 

 peristome rather broadly expanded, shortly interrupted 

 above; columella obliquely truncate below. Axis slender, 

 encircled near the base with a thin, rather wide serrate 

 lamella.
