Description
Size: 25-52 mm

Color: highly variable; usually pale to yellow cream, often with darker blotchy markings. Aperture white. Ground colour white to bluish grey. Pattern of last whorl variable in colour, arrangement and extent. Colour ranges from yellowish brown to olive-brown, blackish brown and orange or red.

A small, thick, broad cone, up to 4 cm, with pointed but rounded spire, and weak shoulder nodules. Moderately small to medium-sized, moderately solid to solid; relative weight of similarly sized specimens may vary by 40%. Last whorl usually ventricosely conical to broadly and ventricosely conical; outline variably convex adapically and mostly straight below; left side occasionally sigmoid. Shoulder angulate to rounded. Spire of low to moderate height, outline slightly concave to slightly convex. Larval shell multispiral, maximum diameter 0.6-0.7 mm. First 2-3 postnuclear whorls tuberculate. Teleoconch sutural ramps flat to slightly concave, with 1 increasing to 4-8 spiral grooves; latest ramps with additional subsutural spiral striae. Last whorl variable in spiral sculpture. Shells with well separated, weak spiral ribs on basal third vary continuously with shells having strong, variably broad ribs or ribbons, usually minutely to strongly granulose and often with 1-2 fine smooth ribs in between, from base to shoulder. Form nigropunctatus with a slightly less solid shell. Last whorl entricosely conical or conoidcylindrical. Spire outline either straight or slightly convex. First 3-5 postnuclear whorls tuberculate. Late sutural ramps with 5-6 spiral grooves. Last whorl consistently with a few well separate spiral ribs near base.
