Description
A small, conical, cap-shaped marine gastropod shell, characterized by its low profile and strong radial sculpture. The shell exhibits a base color of off-white or cream, adorned with distinct radiating brown or tan stripes or bands that originate from the apex. It is a type of "false limpet," belonging to the pulmonate gastropods, which are air-breathing snails that have adapted to marine intertidal life.
