Shell biconic, elongated, spire prominent, its early whorls coronate; whorls about thirteen, the nuclear smooth; the firsteight post-nuclear ornamented by a row of many close-set tubercles near the base of each volution and, posterior to the tubercles, by several incised spiral lines, the tubercles become obsolete rather suddenly on the third volution from the last, but the spirals continue, becoming fainter until they fade out completely on the last whorl; body whorl with a roundly angulated shoulder whence it tapers to the base, marked by fine arcuate growth lines with occasional coarser resting stages; spiral sculpture of coarse, slightly granular threads strongest anteriorly, obsolete posteriorly; aperture narrow, outer lip when complete notched at the summit, then swinging forward in a broad curve, retracted at the base, length of shell, 55, greatest width 24 mm.
