Protoconch unknown. Shell high turriform with weakly convex whorls separated by shallow but well marked suture. Whorls twice as wide as high. Periphery located slightly above fairly sharp transition to moderately flat base. Columella fairly short, terminating in rather deep and oblique, narrow siphonal canal. Columellar folds lacking. Growth lines opisthocline, nearly straight.

Transverse ribs crossed by seven to nine narrow and weak spiral ribs, abapical most demarcating whorl base. Adapical rib beaded and stronger than succeeding ones, demarcated abapically by relatively wide spiral furrow crossing transverse ribs. Later whorls characterized by fine spiral ribs and furrows fading out centrally on whorl. Base smooth but for weak spiral ribs abaxially.</paragraph>
