Small limpet with a variable shape that enables it to occupy small depressions in rock. It is therefore rarely noticed despite being the most abundant limpet on many southeastern Australian rock platforms. It usually has about 12 large ribs with dark markings between and is speckled with black towards the centre of the shell. The species is often found beside the small honeycomb barnacle Chamaesipho tasmanica.
