scarcely to distinguish this portion of the section from, the strata of the 

 Woodmont shale member. The Chemung fauna appears 1250 to 1300 

 feet above the base of the section. An important feature of this section

 collected on the strike of this horizon I/2 mile southwest of the section 

 where the following species were observed : Amhocodia umbonata, Spirifer 

 marcyi var. suyerstes, Spirifer (Delthyris) mesacostalis and Tropidolep-
