the Dunkard fonnatiou. Tlu' foniiatioii ( l>uiikai-il ) was retVrriMl, in 

 1S80, l)y ProfesHors Foiitaiiic and I. ('. White, to the IVrniian. This 

 reference has been dou))ted by most American geolojiists. Recently, 

 however, additional plant evidence has been obtained to show that 

 the beds above the Washington coal, 175 feet above the Waynesburg 

 coal, are clearly Lower Rothliegende (cf. Cnsele:r); and it is not 

 impossible that the Rothliegende boundary may, on the acquisition 

 of further paleontological material, 1)6 shown to lie miquestionably 

 below the Waynes])urg coal. (=" Lower Permian Cass ville. West 

 Virginia, Waynesburg coal." ) 



7. Clendennin, West Virginia. Charleston sandstone formation. The plant bed 



furnishing the insect remains is probably nearly of the age of the Kittanning 

 group in the Allegheny formation in Pennsjdvania. W^estphalian. 



8. Drake Tunnel, (;)ld Forge, Pennsylvania. Antliracite series; Marcy or I) coal. 



This bed proba])ly falls in the stage of the Kittanning group of the Allegheny 

 formation of the bituminous regions. Westphalian. ( = " Middle Coal 

 Measures (Marcy or D) Drake Tunnel, Old Forge, Pennsylvania.") 



9. Empire mhie, Wilkes-Barre, Pennsylvania. Anthracite series; E coal. Referable 



to Freeport group of the Allegheny formation in the bituminous regions. 

 Stephanian. 



10. Fishing Creek Gap in Sharp Mountain, Pennsylvania. Anthracite series; lower 



part; horizon undetermined. Stephanian ? 



11. Frog Bayou, Arkansas. Upper Coal-bearing Division. Probably included in 



the Allegheny stage of Pennsylvania. Westphalian ? 



12. Gibson Fork, near Decota, West Virginia. Upper Pottsville; Lower Kanawha 



series. Probably near stage of the Sharon group in Ohio and Pennsylvania. 

 Westphalian. 

 i;{. Lawrence, Kansas. Upi)er Coal Measures; Le Roy (Lawrence) shales; regarded 

 as near or at the stage of the Conemaugh formation, or possibly as old as the 

 Freeport group of the Allegheny formation. Stephanian. 



14. Lemon's Coal Mine, near Fayetteville, Washington County, Arkansas. .Middle 



Pottsville; Lower Coal-bearing shale. Referable to the Sewanee (Sew ell) 

 stage, in the Appalachian trough. Waldenburg-Ostrauer. 



15. Lorberry Gap, in Sharji Mountain, near Tremont, Pennsylvania. Anthracite 



series; stage undetermined. Stephanian ? ( = "Buck Mountain coal, Lor- 

 berry Gap, T;orberry, Pennsylvania.") 



16. Switchback, near Pittston, Pennsylvania. Anthracite series; D'.'coal. Belongs 



to Allegheny stage in bituminous regions. Westphalian. 



17. Port Griffith, Pennsylvania. Anthracite series; E coal. Freeport stage of the 



Allegheny formation in the bituminous regions. Stephanian. 



18. Pottsville, Pennsylvania. Anthracite series; stage unknown. Westphalian ? 



19. Scranton, Pennsylvania. Uppermost Pottsville; Dunmore coal No. 2. Refer- 



able to Mercer stage of Allegheny formation. Westphalian. 



20. Tallmadge, Ohio. Upper Pottsville; Sharon shales. Lower W^estphalian. 



( = " Lowest coal bed, Tallmadge, Ohio.") 



21. Near Tremont, Pennsylvania. Pottsville; Lykens series; stage unknown. Wal- 



denburg-Ostrauer ? ( = " Lykens Coal Measures, Tremont, Pennsylvania.") 



22. Tremont, Pennsylvania. Anthracite series; Mammoth coal. Probably in Free- 



port stage of Allegheny formation of bituminous regions. Lower Stephanian? 



23. Tremont, Pennsylvania. Anthrat'ite series; Buck Mountain coal. Clarion stage 



of Allegheny formation of bituminous regions. W^estphalian. 



24. Yatesville, Pennsylvania. Anthracite series; Dcoal. Referable to the Fi-eeport 



stage of the Allegheny formation in the bituminous region. Stephanian.
