Description
A medium-sized, oval, and relatively flattened gastropod shell. The exterior surface is rough, with prominent growth lines and some encrustation, displaying a mix of reddish-brown, white, and possibly greenish hues. A distinctive row of 5-7 open respiratory pores (tremata) runs along one edge. The interior is smooth, highly iridescent, and pearly white, with a large muscle scar and the internal openings of the respiratory pores.
