Shell imperforate, ovate-elongate, thin, strongly striate, less so below, the stride conspicuously granulated by others in a spiral direction. Corneous-buff, painted with wide stripes, sometimes lightning bent. Spire conic, regular, the summit minute, acute, whitish; suture indistinctly crenulate. Whorls 8, the nuclear 2 polished, the following ones acutely granulate, a little convex, the last whorl ovate, not inflated, a little longer than the spire, not ascending, nearly smooth beneath. Aperture subvertical (its plane 13 degrees with the axis), acutely long-oval, showing the external stripes within; peristome unexpanded, acute, the margins remote, joined by a very thin parietal callous. Columella slender, strongly twisted and produced, acuminate below, not truncate. Length 68, diam. 39 mm. (Mousson).

According to Mousson this species differs from A. fulgurata and A. varicosa by the acuteness of the summit and the torsion of the columella, which terminates in a point almost without truncation. In the last character it is unlike A. studleyi, which otherwise seems very similar.
