[van Benthem Jutting, 1961]
Shell short-cylindrical, slightly oblique, white, a little shining and transparent in fresh shells. First whorl smooth, following ones ribbed by white, transverse ribs, placed at greater distance than either in O. obtusum v.B. Jutting, O. platycephalum V.B. Jutting or O. uranoscopium V.B. Jutting. With fine spiral striation in the interval between the ribs. Whorl 4, convex. top whorls almost in one plane, and placed somewhat obliquely on the axis of the shell. Suture deep. Last whorl without deviation, widening towards the aperture and directed upward. umbilicus open, but not wide. Aperture round, horizontal, facing the sky. Peristome sontinuous, circular, or rounded triangular, duplex. The parietal margin is pressed against the penultimate whorl, reaching nearly the upper suture of that whorl. Operculum unknown.
