Shell imperforate, ovate-oblong, glossy, rather solid, the spire conoid, turrite, apex a little obtuse. Whorls 8, quite convex, rather regularly obliquely plicate with growth-striae, the suture obsoletely marginate with an impressed line. Last whorl a little shorter than the spire. Aperture ovate, the margins joined by an adnate callous. Columella nearly straight, twisted, narrowly truncate, the lip simple. Color whitish, indistinctly flamed with fulvous streaks, under a buff cuticle. Aperture bluish-white within the throat, the columella and parietal callous vivid rose. Length 95, diam. 53, aperture 45x30 mm. (Dautz.). This shell belongs to the same group as A. tincta Reeve, and is very closely related to that. The sculpture is the same; the shape is a little more swollen, less slender; but the chief difference is in the coloration. In A. oblitterata the longitudinal flammules are inconspicuous or disappear at the periphery of the last whorl, while in A. tincta, on the contrary, these flammules are very dark colored, almost black, and increase in intensity towards the base. Moreover, in A. oblitterata the columella and callous are of a bright rose color, while these parts are milky or bluish-white in A. tincta.
