The Freshwater Gastropods of South Carolina are listed in the left column below, ordered by their record total in our database, together with FWGNA incidence ranks. The suffix "p" marks peripheral species.  This list is compared to lists from Mazyck (1913), with synonyms and other species subsequently reported for the state (Johnson et al. 2013). The four Mazyck entries at the bottom of the table marked "X" appear to represent misidentifications.
