The whorls show 8-9 fine spiral lines and straight axial ribs which turn into strong elongate tubercles on the last two to three whorls. The base bears only growth lines. The outer lip has a keeled wing that is attached to three former volutions of the shell. The holotype is 45 mm high, 29 mm wide and has an apical angle of about 35º.
