Description
Size: 40-73 mm

Color: Ground colour white to bluish grey, variably overlaid with various shades of brown or yellowish orange. Axially streaked or spirally banded shells intergrade with nearly solidly coloured ones. Often, dashed or almost solid brown lines around last whorl. Larval whorls beige to pale brown. Teleoconch sutural ramps irregularly or axially streaked, matching last whorl in colouration. Aperture white to bluish white behind a translucent marginal zone, occasionally pale violet deep within. Periostracum yellowish or orangish brown to dark brown, moderately thick, opaque, with interlaced axial ridges and 10-18 widely and almost equally spaced often tufted spiral ridges on last whorl.

Medium-sized to moderately large, moderately solid to solid. Last whorl conical to ventricosely conical, sometimes approaching pyriform; outline variably convex adapically, less so or straight below; left side concave near base. Shoulder angulate to rounded. Spire of low to moderate height, outline straight to slightly concave or sigmoid. Early postnuclear whorls weakly tuberculate. Teleoconch sutural ramps flat to convex, with 2 increasing to 6-8 (occasionally to 10-11) spiral grooves, often obsolete on latest ramps. Last whorl with variably distinct wrinkled spiral ribs at base. C. h. concolor differs from C. h. hyaena in an usually straighter outline of the last whorl, a consistently angulate shoulder and a consistently low spire.
