Base deep and bluish violet. Young shells uniformly yellow, becoming white in mature species with deep bluish violet at the base, somewhat darker towards apex sometimes with several slightly darker transverse bands varying in width and position.

Shell is hard and thick, moderately large to large, solid to heavy. Last whorl conical; outline slightly convex at adapical fourth, straight below. Shoulder angulate. Spire low to medium height, outline slightly concave to slightly convex. Teleoconch sutural ramps almost flat to slightly concave; late ramps with 3 increasing to 5-6 spiral grooves, either paralleled by additional striae or replaced by numerous striae in latest whorls. Last whorl with weak to obsolete spiral ribs near base; widely spaced fine ribs and wrinkled threads between may extend to centre or beyond. Aperture narrow, fine spiral grooves and axial growth lines present. Periostracum is leathery, thick, opaque and brown, smooth except for collabral growth lines.

It is a vermivore and feeds on terebellids and other polychaetes.
