BAILEY LIMESTONE. 167 



the New York-New Jersey-Maryland area of those species of 

 the strata — related to the Bailey limestone — of Tennessee, 

 Oklahoma, Gaspe, Quebec, and Dalhousie, New Brunwsick, that 

 are not present in the fauna of the Bailey limestone in the Little 

 Saline Creek area but are in the New York-New Jersey-Maryland 

 region. Table 5 is a numerical summary of species, based on 

 tables 1 and 4, that indicates the extent of equivalence between 

 the Bailey limestone and the related strata of Tennessee, Okla- 

 homa, Quebec, and New Brunswick through the species held in 

 common and through the age indications as judged from the New 

 York section of those species of the beds of Tennessee, Okla- 

 homa, Quebec, and New Brunswick that do not occur in the 

 Bailey limestone but are present in New York. 



The Bailey limestone in the Little Saline Creek area of south- 

 eastern Missouri is practically equivalent to the Olive Hill 

 formation plus the Birdsong shale plus the Decaturville chert of 

 western Tennessee; it is partially equivalent to the Haragan shale 

 plus the Bois D'Arc limestone of the Arbuckle mountain region 

 of Oklahoma, to the St. Alban beds of Gaspe, Quebec, and to the 

 Dalhousie formation of Dalhousie, New Brunswick.
