Protoconch unknown. Teleoconch slender turriculate, with evenly increasing whorl width; whorls weakly convex, separated by narrow suture; whorl height corresponding to half or slightly more than half the width. Transition to smooth flat base sharp, marked by weak carina. A second weaker carina may appear on base of adult specimens. Base on early whorls flattened, becoming more convex with growth. Columella smooth. Aperture unknown.

Rare large and low, weakly developed varices occur, becoming slightly more common on later whorls. A more or less distinctly developed spiral rib and succeeding furrow occur adjacent to adapical suture. Interspaces between transverse ribs characterized by an additional five secondary and very weak spiral ribs. Later whorls smooth but for weak spiral lirae crossed by fine, opisthocyrt and slightly opisthocline growth lines. Base with slightly stronger spiral lirae.</paragraph>
