Shell small, narrow, very tall, slowly tapered, sculptured with two heavy nodulous keels and two smooth spiral cords, one immediately above and the other immediately below the suture. Whorls 10 ½ plus a typical blunt protoconch of one smooth whorl followed by 1 ½ of close spaced strong axial folds. There is a slight angulation of the nuclear whorls. On the post-nuclear whorls the smooth sutural cords are equal in size as also are the two heavy nodulous keels which are grouped together at the middle of the whorls. The keels have 14 laterally compressed oval nodules on each of the body-whorl keels. The base is smooth, except for the sutural cord and a thread defining the smooth pillar. Spire five times height of aperture. Aperture subquadrate with a broad shallow basal notch. Outer lip thin, sinuated by the keels.
