 convex. Whorls 5, narrow, slowly increasing, convex, periphery dis- 

 tinctly angled, base flatly rounded, slightly impressed around the um- 

 bilical perforation. Suture rather deep. Aperture transverse, slightly 

 oblique, lunate. Outer lip angled. Peristome simple, thin and sharp, 

 not callous within. Columella very short, arcuate. Inner lip thin, re-

 Spire depressed, broadly convex, its height less than that of the aper- 

 ture. Protoconch flattish, of 1J smooth volutions. Whorls 4|, regu-
