STRATIGRAPHIC SUMMARY. 645 



limestone, Tecumseh shales, Lecompton limestone and Kanwaka 

 shales and Stage F^ including: Oread limestone, Lawrence shales, 

 Kickapoo limestone, LeRoy shales, Stanton limestone, Vilas shales, 

 Allen limestone and Lane shales. Series IL comprises Stage E 

 including lola hmestone and Chanute shales; Stage D including 

 only the Drum limestone ; and Stage C including Cherryvale shales, 

 Dennis limestone, Galesburg shales Mound Valley limestones, 

 Ladore shales and Bethany Falls limestones. 



Finally Series L comprises Stage B which includes Pleasanton 

 shales, Coffeyville limestones. Walnut shales, Altamont limestone, 

 Bandera shales. Pawnee limestones, Labette shales and Fort Scott 

 limestone and Stage A which includes the Cherokee shales. 



In Prosser and Haworth's classification, Stage A corresponds to 

 the Cherokee stage; B to the Marmaton; C, D, E and F to the base 

 of the LeRoy shales, correspond to the Pottawatomie; the re- 

 mainder of F to the Douglas; Stage G including the Scranton 

 shales of Stage H to the Shawnee, the remainder of H, and Stage I 

 to the Wabaunsee, and Stage J to the Council Grove. Stages I 

 and J represent the European Permo-Carbonic (Beede). Where 

 some of the limestones have thinned out, the overlying and under- 

 lying shales have often been united into one formation, with a 

 distinct name; thus the Pleasanton shales, Coffeyville limestone 

 and Walnut shales are replaced elsewhere by the Dudley shales; 

 and the Allen, Vilas and Stanton beds by the Garnett limestone. 



In northwestern Texas, the fossiliferous Permic beds are in- 

 cluded under the term Guadalupian which is divided into the upper 

 or Capitan limestone (1,800 ft.) and the lower or Delaware Moun- 

 tain formation (2,300 ft.). Below this lies the Hueconian or 

 Carbonic limestone. The base of the Capitan limestone according 

 to Beede^^ corresponds in a general way with the base of the 

 Elmdale formation of Kansas. This correlates the Delaware 

 Mountain beds with the upper Carbonic beds of the Kansas section. 

 The faunas however are markedly distinct, representing separate 

 provinces. Overlying the Guadalupian are the Pecos Valley Red
