), 1.7 times longer than wide, imperforate, ovate, sides hardly convex, rather thin. Colour pale yellowish brown, with descending, somewhat oblique stripes of reddish-brown, broken up into separate stripes of different length; upper whorls lighter, corneous, eroded. Surface hardly shining, upper whorls with growth striae, on the penultimate and ultimate whorls transferring into spiral lines of dot-like granulation, more oblong towards the aperture. Protoconch smooth (eroded). Whorls 4.5, rather flat, the last whorl somewhat swollen, suture somewhat impressed, hardly descending in front. Aperture ovate, somewhat skewed, the colour pattern from the outside shining through, 1.7 times longer than wide, 0.65 times the total length; peristome thin and hardly reflexed, whitish with a hue of pink. Columellar margin straight, entering the aperture with a weak fold, hardly dilated and somewhat receding. Parietal wall with a thin, translucent callus.
