Organism information awaits expert curation
Class: Gastropoda

Size: 40-72 mm

Color: Ground colour white, yellow, orange or pale violet. Last whorl with a broad, continuous to sometimes interrupted, yellow or orange to brown spiral band on each side of centre, sometimes extending to shoulder and base. Long light to dark brown axial streaks may extend from shoulder ramp to base, most are interrupted centrally, producing blotches at both edges or only at the upper edge of the central area. Dotted to continuous spiral lines may cover entire last whorl, but vary in number and arrangement. Shells with no axial streaks or spiral lines occur. Larval whorls white to beige. Early teleoconch sutural ramps immaculate, often light pink; late ramps either of immaculate ground colour or more frequently with orange to dark brown radial markings. Aperture white, yellow, orange or violet.

Medium-sized to moderately large, moderately solid to solid. Last whorl conical, outline almost straight, slightly convex adapically in small specimens. Shoulder angulate to broadly carinate, often outwardly curved producing a concave outline at subshoulder area. Spire of low to moderate height, outline concave to slightly sigmoid, apex may project from an otherwise almost flat spire. Larval shell of 2-2.25 whorls, maximum diameter 0.9-1 mm. First 4-6 postnuclear whorls weakly tuberculate. Teleoconch sutural ramps flat to slightly concave, with 1-2 increasing to 4-5 spiral grooves, obsolete in late whorls. Last whorl with a few spiral ribs at base.
