By Von Zittel 20 the John Day has been placed as the equiva- 

 lent of the beds at Sansan and Steinheim. The so-called Ticho- 

 leptus beds of Cottonwood Creek, Oregon, are correlated with 

 the sands of Eppelsheim and the beds at Pikermi near Athens 

 and Maragha in Persia. The beds at St. Gerand-le-Puy and 

 Ronzon are correlated with the White River, which is referred 

 in part to the Miocene and in part to the Oligoeene, while the 

 John Day is called Middle Miocene and the Ticholeptns beds 

 Upper Miocene. 



In an extensive correlation table, W. H. Dall 27 has bracketed 

 opposite each of the formations in question what he regards as 

 their, equivalents in various parts of the United States, and also 

 the corresponding European horizons. The Oligoeene is here 

 admitted as a fourth division of the Tertiary. A part of the 

 table is herewith reproduced :
