This fauna is of typical upper Ohio character (compare lists 2 

 and 3). With one exception (Fusconaia subrotunda leucogona) 

 every form is also found in western Pennsylvania, and this one is 

 only the local representative of Fusconaia subrotunda. Yet this 

 fauna has a somewhat peculiar " facies " in so far as it contains 

 several forms, which elsewhere prefer larger rivers (Fusconaia 

 undata trigona, Elliptio crassidens, Obovaria circulus, Proptera 

 alata). 



In addition I collected some shells in Coal River, at Sproul, 

 Kanawha Co., W. Va. 



1. Fusconaia undata rubiginosa (Lea) 



2. Crenodonta plicata undulata (Barn.)
