Description The diameter of the shell attains 16 mm.
The shell exhibits a prominent wide umbilicus and is characterized by its thin, striated, and corneous texture. The shell contains 7 convex whorls, each gradually expanding in size. The body whorl is rounded and abruptly descends towards the front, featuring a subtle constriction behind the aperture and a compressed area around the umbilicus. The peristome is sinuously curved and reflects inward, displaying a superior internal projection, along with basal thickenings that are somewhat dentiform in nature.G.W. Tryon, Manual of conchology.
