State, are in the Chemung-Oatskill passage beds, and in the 

 Oatskill formation (VIII-IX.) It was supposed that they all 

 belonged to the Oatskill; but Olaypole in Perry Co., and White 

 in the North Branch, Susquehanna region, have found an 

 abundance of Chemung fossils in the many hundred feet of red 

 shales and sandstones overlying the lowest great Fish bed. (F2, 

 XV ; G7.) In Potter Co. several distinct fish horizons are well 

 marked; and throughout the northern tier of counties the spe- 

 cial local horizons of fish do not correspond in different dis- 

 tricts; so that the Upper Devonian age must have had a popu- 

 lous sea from first to last; and in the north-western countit'S 

 the remains of fish are abundant in Subcarboniferous and Car- 

 boniferous deposits fPocono X, Mauch Chunk. X/, Conglom-
