Description
An ornate and striking marine gastropod shell, characterized by its elongated, fusiform shape and prominent, frilly, wing-like axial varices. The shell exhibits a high spire and a relatively long, straight siphonal canal. Its exterior is predominantly off-white to pale cream, often with subtle purplish or pinkish tinges, especially on the frills. The interior of the aperture is a vibrant deep pink to purplish-magenta, providing a beautiful contrast.
