Image copyrights: Coneshell

Size: 55-98 mm

Color: Ground colour white. Last whorl with broad, brown or olive spiral bands, leaving white bands at shoulder and centre. Central band edged with dark brown markings, some of which cross the band, subshoulder band crossed by dark brown streaks. Spiral colour bands interspersed by spiral rows of dark brown coarse dots or axial streaks of varying length. Numerous spiral rows of minute brown dots extend from base to shoulder, often sparse within white bands and densely clustered anteriorly, producing a dark brown base; dots become axially rather than spirally aligned during growth. Larval whorls yellow, adjacent sutural ramps greenish yellow. Later sutural ramps white, with variably broad, brown to black radial blotches, some of which extend as streaks to subshoulder area. Aperture white. Pattern consistent from juveniles of about 15 mm to the adult stage.

Moderately large to large, solid. Last whorl conical or ventricosely conical to broadly or broadly and ventricosely conical, outline convex near shoulder, less so or straight below, left side concave near base. Shoulder angulate, sometimes subangulate. Spire low, outline slightly sigmoid, straight or concave. Larval shell of 3-3.5 whorls, maximum diameter about 0.9 mm. First 0.5 postnuclear whorls tuberculate, smooth within following 0.5 whorl. Teleoconch sutural ramps almost flat to slightly convex, with 2 increasing to 5-7 spiral grooves. Last whorl with widely spaced, often weak spiral ribs at base; in subadults, ribs followed by variably spaced spiral rows of punctations sometimes retained basally in small adults.
