In this Hamburg section the oolite bed No. 7 in section A, 



with a thickness of two inches or less, increases to 15 feet in 



section B, and apparently replaces the blue shales, bed No. 



6, of section A, and possibly also the upper portion of bed 



No. 5. These oolites are abundantly fossiliferous and have 



furnished the following species, those marked with an asterisk 



being also recognized in the Glen Park fauna, 



*OrthotfiPtes chemungtnsis (Con.). 

 *Chonetes sp. 

 Camarophoria'? sp.
