Description
editThe length of the shell attains 14 mm, its diameter 8 mm
The shell is acutely ovate and dextral, delicately striated with growth lines and attractively malleated. Its surface is a dirty whitish hue, adorned with a variable brownish-olivaceous epidermis. There are six slightly convex whorls, with the first three prominently marked by strong radial sulcations. The suture is simple and well-defined.
The aperture is white, with a thin peristome that is subtly thickened on the interior. The columellar fold is slender and understated.[2]
Distribution
editThis species is endemic to Hawaii, occurring on Maui island.
