Ferrissia wautieri (Mirolli) has hitherto only been reported with certainty in England from greenhouses and aquaria. In 1977 it was discovered in a small stagnant pool away from houses in Sussex. Shells of Ferrisia can be distinguished by their small size and blunt apex which points to the left and has fine apical ridges.
