Description

A medium to large-sized marine gastropod shell, characterized by its elongated, fusiform (spindle-shaped) form. The shell has a tall, pointed spire composed of several gradually increasing whorls. The body whorl is large and somewhat inflated. The aperture is long and narrow, with a smooth outer lip and a columella (inner lip) featuring several distinct folds. The surface appears relatively smooth with fine growth lines.
