Descrição original:

(Hass, 1961): “Shell of medium size, elongate conic, rather thin, pinkish white, with no traces of sculpture but for shght incremental lines. Seven whorls, of which the three first ones grew slowly and regularly, the last ones more rapidly; the last descends slightly toward the aperture. The obesity of the whorls increases toward the aperture; the suture is simple. The apical whorls appear smooth, most probably due to wear. Aperture elongate eUiptical, about 4/9 of the height of the shell; the lip is reflected and forms a rather wide, white peristome, which covers the deeply rimate umbihcal region; the ends are hardly converging, but are united by a rather thick, white callus.”
