Description
Size: 75-95 mm

Color: Ground colour white to cream, often partially suffused with pink or tan. In Andaman Sea shells, last whorl with closely set spiral rows of brown to reddish brown axial dashes following spiral ribbons basally; lineate pattern extending on shoulder ramp. Paler brown spots and flecks forming 3 interrupted spiral bands, below shoulder, just above centre and within basal third. Solomon Island shells with rather broad, straight to wavy, continuous axial lines from shoulder ramp to base. Siphonal fasciole and notch white in shells from Solomon Islands, white to cream or pink in shells from Andaman Sea. Apex immaculate white. Late sutural ramps with brown radial lines. Aperture white to pale pink, pink in subadults.

Moderately large to large, moderately solid to solid. Last whorl narrowly conoid-cylindrical, outline slightly convex at adapical third, almost straight below. Aperture somewhat wider at base than near shoulder; siphonal fasciole prominent. Shoulder subangulate. Spire of moderate height, outline straight to slightly concave. Larval shell of about 3.25 whorls, maximum diameter 0.7-0.8 mm. About first 4 postnuclear whorls tuberculate. Teleoconch sutural ramps flat, with 1 increasing to 5-8 spiral grooves. Last whorl with widely spaced spiral grooves on basal half; intervening ribbons rather weak, with or without a median groove, spiral sculpture less prominent in shells from Solomon Is.
