An interesting feature of the section is the recurrence of the Tropido- 

 leptus fauna in the lower Chemung conglomerate, 600 feet ahove the 

 base of the Chemung member. This fact is of imporance stratigraphically 

 because it permits the correlation upon faunal grounds of this conglom- 

 erate M'ith a similar stratum west of Sideling Hill Creek. 



The Jennings formation outcrops in the anticlinal area between Side- 

 ling Hill and Town Hill, at the southwestern extremity of which Paw- 

 paw, West Virginia, is situated. The Potomac Eiver meanders in this 

 district in great bends, affording admirable sections. Those described 

 are considered in the order of their location from northeast to south- 

 west. 



X. Section on Sideling Hill Ureek 

 A short section is exposed on the west bank of Sideling Hill Creek, 

 two and one-half miles above its mouth, and one mile down the stream 

 from the home of Mr. Stottelmeyer. The horizon is probably the upper 

 conglomerate of the Parkhead member and is situated approximately 

 1700 feet above the base of the Jennings as shown by other sections in 

 the area. The following fossils were found at this place: Atrypa reti-
