The biconical shell shows spiral lirae, with or without strong axial ribs. The protoconch contains 1½ - 2 smooth whorls. The distinct shoulder angle is usually very strong and crenellated by axials (when present). The columella shows a thin callus but no pleats. The outer lip is thin. The anal sinus is deep and wide. The small, translucent operculum has an oblanceolate shape and a terminal nucleus.[2]
