The taxonomy of South African Siphonaria is reviewed. We conclude that nine species are valid. These are: S. anneae Tomlin, 1944; S. capensis Quoy & Gaimard, 1833; S. compressa Allanson, 1959; S. concinna Sowerby, 1824; S. dayi Allanson, 1959; S. nigerrima Smith, 1903; S. oculus Krauss, 1848; S. serrata (Fischer, 1807) and S. tenuicostulata Smith, 1903. Of these, Siphonaria nigerrima Smith, 1903, has been incorrectly synonymized with Siphonaria carbo Hanley, 1858, which is not present on South African shores. S. aspera Krauss, 1848 is reduced to a junior synonym of S. Serrata (Fischer, 1807). Shell characteristics and mode of larval development are described for these nine South African species. All species deposit benthic egg masses and development may be either planktonic with swimming veliger larvae (S. capensis, S. concinna and S. oculus) or direct, with crawling larvae emerging from the eggs (S. anneae, S. compressa, S. dayi, S. nigerrima, S. serrata and S. tenuicostulata).
