Description
The length of the shell attains 11¼ mm, its diameter 6¼ mm.The shell is solid, imperforate, and ovate-globose in shape, with a livid chestnut coloration. The apex is pale, while areas near the suture and the anterior portion exhibit a whitish hue. It consists of six whorls, which are slightly tabulate posteriorly, adding a subtle angular appearance.
The aperture is rounded, with a simple lip that remains unadorned. The columella is excavated and covered by a callus, featuring a small but distinct fold. This combination of features gives the shell a sturdy yet refined character.
This is a small, solid species characterized by a livid hue, with the apex and the area near the suture displaying a pale, whitish tone. The shell transitions to a milk-white coloration near the termination of the body whorl at the aperture, adding a delicate contrast to its overall appearance.
