About Half a mile north of East Stroudsburg, another anti- 

 clinal fold brings to the surface the Corniferous limestone and 

 then there are no more noticeable exposures of rocks along the 

 railroad until a point is reached a short distance north of 

 Gravel Place. At this locality, about two and one-half miles 

 from Stroudsburg, are exposures of rather coarse arenaceous 

 shales on the northeast side of the railroad. The fossils are 

 quite abundant, especially Vitulina pustulosa Hall. The fol- 

 lowing species were found at this place (No. 1475 C 2 and C 3 ).

It will be noticed that the above list is a typical Hamilton 

 fauna and these arenaceous shales and thin sandstones make 

 an outcrop nearly one mile in width. 



Near the top of the above zone is an arenaceous, slightly 

 calcareous shale which in places, especially where not weath- 

 ered, forms a massive stratum of very compact rock. There is 

 a good exposure of this zone' by the side of the Stroudsburg 

 and Spragueville highway, on the western side of Brodhead 

 creek about one and one-half miles below Spragueville and a 

 short distance south of Mr. E. Bonynge's house f Fossils are 

 very abundant at this exposure, especially corals and crinoid 

 stems ; but there are also numerous specimens of brachk^ods. 



Fauna of No. 1475 C 5 . 



* The relative abundance of the species is indicated as follows : 

 act = very abundant, a — abundant, cc — very common, c = common, r = rare, 

 rr = very rare. 



f This locality is described by Prof. White in G 6 , pp. 109, 271 under the head- 

 ing of the "Tully Limestone horizon."
