Shell ovate, ventricose, thin, rufous or greenish-fulvous, streaked with darker, with an oily lustre. Spire submamillate with acute apex, flammulate with red. Whorls 8,5, convex, granulated to the periphery of the last, which is ventricose, rugulose striated, and longer than or rarely equalling the spire. Columella straight, arcuate anteriorly, abruptly truncate at the base. Aperture elliptic-oval, pearly within, the peristome unexpanded, thin, margins joined by a superficial callous. Length 74, diam. 40 mm.
Curious for its thin texture, brilliant gloss and ventricose shape. There is a less ventricose form with longer spire of nearly a whorl more, and much thinner yellowish-green shell. Length 62, diam. 33 mm.
