Shell moderately large for the genus; sutures deeply impressed, whorls rounded and somewhat shouldered; color reddish brown, the pillar a darker shade and the shoulder of lighter intensity. Protoconch of 3 whorls, first 2 smooth with impressed sutures, third bulging or keeled at the periphery and having narrow axial riblets; postnuclear whorls 6. Axial ribs 11 on early whorls, increasing to 16 on final whorl, ribs narrow, extending from suture to suture, flexed at the shoulder and slanted protractively across the body, whorl, terminating at one of the strong spiral cords on the pillar; spiral sculpture of 5 major cords per whorl, beaded on crossing the axial ribs, interspaces with fine spiral striae that override the ribs; base with 4 additional major cords, the lowermost strongly beaded at the terminations of the axial ribs; pillar with 2 major and 2 minor spiral cords below, uncrossed by the axial ribs. Sinus broad and shallow, bounded on the inside by a parietal extension of the lip; lip edge thin, strengthened behind by a varix or massive rib, stromboid notch shallow; anterior canal broad and unnotched, inner lip not raised. Height, 9.9 mm., diameter, 3.2 mm.

This is the first recent member of a genus otherwise known from three species from the Caribbean Miocene, differing from all in having more rounded whorls, more deeply impressed sutures and a less constricted pillar.
