Popis

Shell slender, solid, pure white, with three translucent apical and six opaque whorls, obtusely angulated at and a little concave behind the periphery. Nuclear turns glassy, smooth, the others engraved throughout with extremely fine, sharp, well marked spiral striae crossed by about (on the last whorl twenty-five) rounded smooth moderately elevated strong transverse ribs, very obliquely set, appressed a little at the suture, but with no sharp angles, spines, or irregularities. These ribs are separated by interspaces no wider than the ribs themselves, nearly hiding the spiral sculpture; base handsomely rounded, without disk or cordon, imperforate; aperture subcircular, lip thickened but not varicose. Lon. 5.1 mm, max. lat. 2.0 mm.
