Whorls moderately convex, suture distinct, not appressed or channelled; sculpture of the last four whorls of retractively oblique fine axial threads regularly disposed, with about equal interspaces, covering the entire shell, but a little less distinct near the aperture; outer and inner lips approximated, connected over the body with a thin layer of callus, aperture egg-ovate, the lip widely reflected and sharp, the pillar simple; a section shows that above the perforation in the last whorl the hollow of the axis expands, funnel-like, and in the next preceding whorl is anteriorly contracted and posteriorly expanded, and similarly throughout the spire.”
