The surface of the shell is smooth with faint sinuous growth lines. The labial callus is well-developed and conspicuous. The labrum is not thickened and has a moderately quadrate profile. The columella is recurved backward near the base. The base of the labrum does not extend as far as the end of the columella. The anterior of the body whorl has fine axial grooves. Distribution.
