Whorls moderately convex and not shouldered, last whorl angular at the periphery, moderately convex below the periphery. Protoconch whorls somewhat convex, with spiral sculpture predominant but inconspicuous, very fine, well-spaced, thin threads; radial sculpture inconspicuous. Teleoconch: subordinate spiral striation, first whorls with traces of very inconspicuous, moderately-spaced striation, outer whorls above the periphery with a very fine, very densely placed, somewhat wavy striation (more than 100 striae on the last whorl); below the periphery almost smooth, with faint traces of an even finer spiral striation only towards the periphery. Radial sculpture teleoconch: Above the periphery with coarse, distinctly raised growth lines at irregular intervals; below the periphery these are slightly less distinct. Umbilicus closed.
