Description
editThe length of the shell attains 5.1 mm, its diameter 2 mm. It is moderately sized, spirally lirate, and axially costate shell. The shell has a high spire, about twice the height of the aperture, with lightly convex outlines and a flat-topped early whorls structure. The last two whorls bulge anteriorly, with a moderately distinct suture and clasping last whorl. The aperture is angled behind, strongly notched below the columella, and expands laterally at the base.[2]
Distribution
editFossils of this species were found at Kaipara, Northern New Zealand.
