Description

(Described as Endodonta (Pterodiscus)) The shell is umbilicated, depressed, thin, or fragile, with a translucent horny-brown coloration.

The whorls are finely and densely striated, with the body whorl sharply keeled at the periphery and distinctly carinated around the umbilicus. The aperture is oblique and toothless, with a thin, simple lip.

Distribution

It is endemic to the Hawaiian Islands.
