Shell of moderate size, 13-19 mm., claviform, with a tall spire of rather flattened out¬lines, and a rounded body-whorl, contracted to a distinct neck, and a moderately long, slightly flexed, weakly to distinctly notched anterior canal. Protoconch of two polished prominently peripherally keeled whorls. Adult sculpture of numerous rather flexuous fold-like axial ribs, deeply incised by spiral linear grooves. Sinus subsutural, rounded, rather wide and with a slightly flaring edge. Outer lip thin; inner lip smooth callused, with¬out, or with a very slight parietal callus pad. Radula prototypic, with a mere vestige of a central plate, a deep narrow-based comb-like lateral, and a long slender flexuous simple-pointed marginal, bifid basally and for two-thirds of its length
