the Monongahela and Ohio rivers. The series l>e^ins with the iota' 

 shales of the Waynesburg coal, and includes all of the beds above, 

 about 1.100 feet in all. II consists of massive sandstones, red and 

 variegated shales, wit 1 1 thin limestones and impure, mostly worthless, 

 coal beds. 



The fauna has never been studied, but appears to be of t'resli-w ater 

 origin, and is largely composed of bivalve crustaceans, while the flora 

 lias a distinctly Permian facies, containing OaUipteris confer fa. Sapor- 

 tcea Ta)tin}>t<ris, Baiera, and other Permian types, while the species 

 that resemble Coal .Measure forms also occur in the Wichita, or undis- 

 puted Permian of Texas, so that the evidence is now complete that this 

 Dunkard Creek series, formerly called Pernio Carboniferous, is the 

 American equivalent of the European Permian.
