FAUNA OF ALABAMA. 



FRESH WATER AND LAND SHELLS. 



There is no State in the Union that affords a more di- 

 versified Molluscan Fauna than is found within the limits 

 of Alabama. While exhibiting no marked superiority in 

 the number of species that are classed as Land Shells, and 

 possibly displaying a meager list of aquatic pulmonates, it 

 is remarkably rich in fresh water bivalves (Unionidse), and 

 in an operculate class of aquatic univalves, chiefly of the 

 family Mela^idse. 



The list of Species here presented is compiled from vari- 

 ous sources, chiefly the writings of Isaac Lea, L. L. D., 

 who has writt jaore on the fresh water shells of North 

 America than till other original writers together. The 

 compilations and writings of Mr. W. G. Binney have af- 

 forded much aid in compiling the pulmonate species. The 

 writings of Thomas Say and other distinguished American 

 Conchologists, have also been consulted. 



The verification of facts relative to local and geograph- 

 ical distribution, has been greatly aided by material pre- 

 sented by various gentlemen, who have, at different times, 

 collected shells in various parts of Alabama. Among the 

 gentlemen to whom the greatest credit is due for speci- 

 mens and notes on Geographical Distribution, may be 

 mentioned Dr. E. B. Showalter, of Mobile, formerly of 

 Uniontown, who, prior to 1861, was largely interested in 

 bringing to light many species which were previously un- 

 known. Later, Mr. Truman H. Aldrich, of Montevallo,
