Description
A medium-sized limpet shell, oval to subcircular in shape with a moderately high, conical profile. The exterior surface is rough and exhibits a base color of yellowish-brown to greyish-white, with distinct darker brown to black radial streaks or mottling, particularly towards the shell margin. The margin itself is often dark and can be irregular, adapting to the substrate. The shell in the image shows clear radial ribbing and a somewhat eroded apex.
