Shell small, elongate-ovate, covered with a thin periostracum. Nuclear whorls decollated; the postnuclear whorls are rather broadly slopingly shouldered at the summit and crossed by strong, retractively slanting, axial ribs, which are cut into segments by two or three deeply incised spiral lines. Periphery well rounded. Base short, strongly rounded, marked by the continuation of the axial ribs and deeply incised spiral lines which again cut the ribs into segments, but these here are shorter than on the spire. Columella moderately long, almost straight, marked by spiral threads which decrease in size from the insertion of the columella toward the tip. Aperture pear-shaped, strongly channeled anteriorly with a slight sinus in the outer Up at the angle of the shoulder; outer lip thin, rendered somewhat wavy by the spiral sculpture; inner lip reflected over the columella, which it slightly excavates, and also over the parietal wall is similarly treated. Type: Nodotoma impressa (Beck) Morch.
