TRANSLATION
OF THE LATIN TEXT. — Sinistral shell, subulateelongated, acute, solid, white, marbled with red-brownish spots. Whorls are about 18-20; the embryonic whorls are five, slightly rounded, carinated and striated; intermediate whorls are concave, separated by an indistinct and moderately crenulated suture, with two protruding, acute and smooth keels. Interspaces between the keels are cancellated, sculptured with really small striae and the intermediate spiral cord is smaller, adorned by tubercles. The last whorl is flattened below, with six spiral cords, first and third cord acute and carinated, other cords are tubercled. Siphon is short, partially closed, obliquely curved, yellowish. Slightly rounded aperture, internally bearing a channel under the suture, fissured over the edge of the suture. Arched columella, brownish. The columellar lip is roundly protruding and joined to the beginning of the siphon. — Length
8-9 mm
