Description
A small, conical, limpet-like shell with an oval base. The exterior surface is characterized by a cancellate sculpture, formed by prominent radial ribs intersected by finer concentric growth lines. A distinctive tear-drop or keyhole-shaped foramen (apical opening) is present at the apex. The shell margin is crenulated due to the radial ribs. The interior view reveals a smooth surface and an internal septum located beneath the foramen. The shell is uniformly white or off-white in color.
