Spire whorls weakly inflated, with
deeply incised suture, 4 or 5 spiral cords alternate with deep spiral grooves and overlain by numerous axial ridges, forming a pattern of squared nodules. Body whorl wide, regularly rounded, with numerous beaded spiral cords on the base, and a thick axial varix on its left side. Earlier varices randomly distributed. Outer lip of the aperture thickened and widely flared, smooth to slightly crenulated, expanded anteriorly to the base of columella over the short, tubular siphonal canal. Columella glazed, with 2 spiral ridges anteriorly (hardly visible from the outside in full grown specimens with intact outer lip).
