Description
The height of the shell attains 7.5 mm, its width 3 mm.The strong, whitish shell has a fusiform shape. It contains six whorls, of which three form a large, convexly-whorled, smooth and shining protoconch. The whorls of the teleoconch are moderately convex, slightly concave below a strong, yellowish, subsutural spiral. The sculpture consists of this spiral and some other ones, 7in number on penultimate, 22 and a few intermediate ones on last whorl, stronger on lower part of upper whorls and on median part of last one. The spirals are crossed by conspicuous growth-striae, stronger in the interstices, which are broader near the base. The aperture is oval and angular above. The peristome is strong, with a rather wide, deep sinus above, protracted lower on, bordered exteriorly by a strong, rounded rib. The columellar margin is slightly concave above, nearly straight below, with a strong layer of enamel, forming a wall at its upper extremity, bordering the sinus. The siphonal canal is rather wide, slightly directed to the left. The interior of the aperture is smooth and white.
