Shell of moderate size, 11.4 mm., slender, with sharply angulate whorls, strongly constricted at the sutures. Spire tall, turreted, body-whorl short, rapidly contracted to a short unnotched anterior canal. Protoconch of three rapidly increasing whorls, last two strongly keeled and bearing beads, from which fine axial riblets extend. Aperture wide, outer lip not varicose but incurved with a thin edge. Sinus broad and shallow. Adult sculpture of rather distant heavy varix-like axials, overridden by finely granulose spiral cords and threads. Somewhat related to Mangelia but the beaded protoconch is distinctive. Range — 100 fathoms off Barbados. Miocene, Florida and Jamaica.

Shell small, slender, whorls very strongly constricted. Nucleus consisting of three rapidly enlarging whorls, the apex rising abruptly, the last two whorls strongly keeled and bearing beads on the keel, from which fine axial riblets extend. Aperture wide, anterior canal short, but strongly constricted, unemarginate. Outer lip not varicose, anal notch very shallow and broad. Sculpture consisting of heavy varix-like ribs, overridden by strongly frosted spiral threads of several orders of magnitude.
Saccharoturris is a genus of "Mangilias" that has a beaded nucleus, unemarginate canal, very shallow anal notch, and strongly frosted.
