Description
A marine gastropod shell, characterized by its smooth, glossy, and ovate-conical form. The shell exhibits a creamy white background adorned with distinctive reddish-brown axial streaks and bands, particularly prominent on the upper whorls, often forming a clear white band centrally. The spire is low, contributing to its overall streamlined appearance.
