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 " fácies " in so far as it contains 

 several forms, which elsewhere prefer larger rivers {Fusconaia 

 undata trigona, Elliptio crassidens, Obovaria cir cuius, 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.)
