Description

edit

(Original description as Ancillaria obtusa) The shell is ovate, thick, and glossy, ranging in color from white to pale fulvous. It has approximately five whorls, with a short, rounded spire lined and covered by a thick callous deposit. The apex is blunt and obtuse. The body whorl is bordered by broad, milky zones at both the upper and lower edges and displays linear markings at the base.

The columella is coated with a thick layer of enamel that extends onto the body whorl and appears slightly wrinkled and twisted near the siphonal canal. The outer lip is thin and sharp. [2]

Distribution

This marine species is endemic to Australia and occurs off New South Wales, South Australia, Tasmania and Victoria.
