(Original description) The turbinate shell is dark brown and dull.

The remaining whorls, besides concentric wavy striae, show 4—5 radiate, brown, white-edged, periostracal processes per millim., directed backward, with many hairlike growth-lines between.

The outer lip is simple, the margins slightly converging.

The columella is vertical, reflexed above and slightly covers the umbilicus.
