(Original description in Latin) The solid shell is imperforate, pyramidally conical and chestnut-colored. It is very shiny, finely striate and spirally lined. The spire is acute. The shell has seven rather convex whorls, which are disjoined by a thin suture. The body whorl is faintly angled, convex at the base, and it nearly occupies half the length of the shell.
