Sinual band situated on the widest part, broad and flattish, with a fine linear groove on each side. Ornamentation above the sinual band consistingof two or three fine lines ; below, of two somewhat rounded bands, with an additional band on the body-whorl. Both the lines and bands are separated by grooves, those between the bands being the deepest. Lines of growth distinct, causing the spiral lines and bands to be almost beaded where they cross ; on the sinual band they form strong raised crescents. Sutures deep, rather oblique.
