Description
A medium-sized marine gastropod shell, distinctively characterized by its fusiform shape and three prominent, blade-like, and often frilly or undulating longitudinal varices (wings). The shell features a moderately high spire and a distinct, relatively long siphonal canal. Its coloration is typically off-white to creamy white, sometimes with subtle brownish or reddish-brown markings, especially along the varices. The aperture is oval, with a smooth inner lip and a denticulate outer lip.
