Distribution maps & pictures added by Kathryn E. Perez, University of Alabama

All distribution maps drawn from:
Hubricht, Leslie. 1985. The distribution of the native land mollusks of the Eastern United States. Fieldiana, Zoology, N. S., No. 24: 1-191, 523 maps.

Maps are intended to be a rough guide, remember that land snail species distributions are not continuous but occur in pockets of appropriate habitat throughout the range of a species. Also, many regions have not been surveyed for land snails and as we gain knowledge some areas may be added to the distributions shown.

The late Dr. R. Tucker Abbott was the first to encourage me to work on non-marine mollusks. Following his advice has opened up a whole new world waiting to be discovered. Mr. Steve Ahlstedt of the U. S. Geological Survey offered encouragement and loaned me books to help me learn the taxonomy of terrestrial snails. The following people provided field support: Jim Godwin, Alabama Natural Heritage Program; Louis Levine-Fields, Cumberland Science Museum, Nashville, Tennessee; Stuart McGregor, Geological Survey of Alabama; Frankin Pritchett of Hollywood, Alabama; Ashley Shelton, Carrie Shelton, Jonathan Shelton, and Matthew Shelton of Mobile, Alabama; Jason Shelton of Pisgah, Alabama; and David I. Withers, Tennessee Natural Heritage Program.
