Sortable Taxonomic Index
The 113 species and subspecies currently covered by the Freshwater Gastropods of North America project are ordered below by Subclass, Family, Genus, species, and (in some cases) subspecies. Users who do not find specific or generic nomina expected in the list below are referred to the alphabetical index for synonyms.

Click the state column headers to sort by presence/absence in each state. Click a second time to reverse the yes/no sort. Also note, that for economy of space, two-letter abbreviations are used to denote the six regions—Mid-Atlantic ("Matl"), Virginia (Atlantic), North Carolina (Atlantic), South Carolina, Georgia (Atlantic), Ohio and East Tennessee—as defined in each region's section.
