Table 1

The 39 freshwater gastropod species of Georgia Atlantic drainages are listed in the left column below (combining subspecies), ordered by their number of records in our database, with FWGNA incidence ranks.  The letter "p" marks peripheral species, and asterisks* mark species demonstrating non-apparent rarity.  This list is compared to the review of Johnson et al. (2013), giving synonyms common in the modern literature.
