 Shell cylindric, the upper third slowly tapering to a rather 



wide truncation, thin, pale corneous, translucent, the axis 

 showing through; surface glossy, smooth, with short, rather 

 coarse, loiv stria ~beloiv the sutures, the last whorl distinctly 

 striate, its latter half having well spaced thread-like rib- 

 striae, becoming more crowded near the lip. Whorls 15-17, 

 moderately convex, the last becoming free and descending 

 in front, rounded and without a carina below, the neck white 

 above, and grooved below the umbilical chink. Aperture 

 circular, the peristome narrowly reflexed. Axis with three 

 lamellae, the upper quite wide, the lower very small and 

 bearing very widely spaced, long, curved and very delicate 

 white spines. 



Length 16.5, diam. 3.2 mm. ; whorls 16 1 /o.

The short, subobsolete striae under the suture are charac- 

 teristic. It is somewhat larger than U. brunnescens with 

 more whorls and different sculpture, and the lamellae differ 

 somewhat, especially in the last whorl.

 Shell subrimate, cylindric-turreted, rather solid, nearly 



smooth, whitish; spire generally truncate; suture subcremi- 

 late. Whorls remaining 11-12, nearly flat, the last not 

 keeled at the base, striated anteriorly, shortly free. Aper-
