Shell ovate-conic, rather thin but strong, pure white under a thin straw-yellow cuticle, which is absent from the early whorls. Spire rather long and straightly conic, the apex obtuse. First whorl smooth, the next faintly rippled, the rest of the whorls closely and finely striate, the stride more or less irregular or anastomosing, decussated. On the last whorl the striae are coarser, and obsolete except near the suture, giving place to very weak, coarse wrinkles; and the spirals disappear except near the suture, where they are rather weak. Whorls 8%, convex, the last rather inflated below. Aperture ovate, bluish-white within. Columella narrow, white, concave above, very narrowly truncate below, a small ridge, terminating at the basal notch, behind it. Parietal callous a transparent film. Outer lip brownish at the edge. Length 70, diam. 34, length of aperture 34.5 mm.

This rather glossy white species is distinguished by its rather long spire, quite sinuous columella which is only narrowly truncate, and the small aperture, less than one-half the length of the shell. The last whorl is smooth except near the suture.
