Description
A very small, conical marine gastropod shell, uniformly white or off-white, characterized by a distinctive apical opening (foramen or 'keyhole') at its apex. The shell surface is finely sculptured with numerous radial ribs and concentric growth lines, which intersect to create a beaded or reticulated pattern. Its shape is cap-like, with an oval base.
