Shell rather small, spirally scored, oval, suhrylindriral, bluntly 

 rounded in front, with a low subscahir spire crowned \\itli :i minute 

 prominent sinistral apex turned uponitssi<l . Sculpture: Longitu- 

 dinals there are faint growth -fur rows drawn at the top into short 

 very oblique folds. Spirals the whole surface is scored with fine 

 furrows, which are remote above but closer in front, where the inter- 

 vening surface is rounded; a rounded keel lies below the suture. 

 Colour trauslucent white. Mouth markedly shorter than the shell, 

 straightish, clavate to pear-shaped, narrow and channelled above. 

 Whorls 4, exclusive of 1-1 of the apex which is sinistral. Outer lip 

 straight, very slightly appressed above, where it is separated from 

 the body of the slight, shallow sutural canal. Top: there is a short 

 distinct subscalar spire, in which the first regular whorl hardly 

 shows, but which is crowned with the small sinistral half-turned over 

 apex. Inner lip: there is a thin but distinct labial pad ; the curve 

 of the body is nearly straight, but is convex in front ; the pillar is 

 very oblique, broad, flat and patulous, with a very broad, scarcely 

 twisted tooth, which is longitudinally furrowed so as almost to be 

 double ; in front of this tooth the pillar is truncated at its junction 

 with the outer lip. Alt. (M3 in., diam. 0'055. Mouth breadth at 

 same place, 0*014 inch. (Wats.).

This differs from Utriculus avenarius in the shape of the shell and 

 of the spire, and in the apex and pillar. Utriculus cancUieulatut 

 (Say), is much stumpier, and has a lower spire. The upturned aper 

 is like that of Odostomia lactea. (Wats.).
