term Fulton has been applied and the major part of the 

 formation formerly called Utica is now known by Orton's 

 term Eden. The Fairview and McMillan formations have 

 until recently been included under one formational name. 

 For many years, this series of strata was considered to be 

 the equivalent of the New York Lorraine, and was known 

 by this name. Later, as it became evident that these 

 strata were not the exact equivalent of the Lorraine, the 

 name Maysville* was proposed. This name was used for 

 several years, bjt is now being superseded by two names, 

 Fairview and McMillan, which Bassler'' has proposed for 

 the two divisions of the Maysville which he raises to forma- 

 tional rank. These two formations, together with the Eden 

 and Utica, he included in the Covington group. Recently 

 the Richmond has been referred to the lower Silurian." 



The following table is intended to show the scope and 

 equivalents of the various names which have been applied 

 to parts of the Cincinnatian series in the vicinity of Cin- 

 cinnati.
