Outer lip a little patulous above, a good deal so on the base ; it 

 rises from the body-whorl at a right angle but immediately bends 

 downwards and runs forward to the base quite straight and parallel 

 to the axis; across the base it is slightly emarginate. Inner lip: a 

 thin, narrow glaze crosses the body and borders the pillar, which is 

 narrow and concave, with a rounded, slightly twisted, and feebly 

 marginated edge. There is no tooth. Alt. 1 in. ; diam. 0*5. Penul- 

 timate whorl, height 0'2. Mouth, height 0'65 ; breadth O31. This 

 fine species is represented by only one somewhat broken specimen.

Shell small, ovate, thin, translucent white with flatly rounded 

 whorls, a short subscalar very bluntly tipped spire, a largish roundish 

 mouth, sinuated outer lip, and edentulous pillar. Sculpture: 

 Longitudinals there are numerous, unequal, sinuous hair-like, 

 obsolete lines of growth. Spirals the whole surface is scored with 

 Hattish rounded threads and shallow furrows of half their breadth 

 between ; these become feeble in the middle of the whorls ; the fur- 

 rows are not stippled. Color translucent-white and glossy. 

 Spire conical, scarcely scalar. Apex extremely blunt, being sud- 

 denly truncated and flattened ; the extreme tip is very slightly in- 

 verted. Whorls 4i, constricted above, flatly rounded in the mid- 

 dle, and very faintly constricted below ; the last is very little 

 tumid, with a rounded and slightly produced base. Suture strong, 

 slightly oblique, impressed and slightly channelled. Mouth roundly 

 pear shaped, very bluntly pointed above. Outer lip: there is a 

 strong, shallowish and wide sinus above; below this the lip edge 

 (straight in its direction) is prominent, with a very slight emargi- 

 uation on the patulous and rounded base-line. Inner lip: an ex- 

 fly thin and narrow glaze crosses the body, which is scarcely 

 ex ; the line of junction with the pillar and out to the point of 

 the shell is roundly concave: the lip edge on the pillar is narrow 

 and sharp, and there is behind it a small furrow. Alt. (rl in.;
