(Original description in Latin) The shell is rhomboid-fusiform, thick, and shiny. It is whitish but livid anteriorly. The shell is inscribed with 8 ribs and very fine revolving striae. There are 6 angular whorls, and the suture is impressed. The aperture is piriform and is half of the total length, tapering to a point anteriorly. The outer lip is simple and thickened, and the sinus is barely noticeable. The columella is straight and livid. [3]
