Cheilaxthites obtusilobus (Brongniart) Goeppert 



Nov. Act. Acad. Caes. Leop. — Car., vol. 17, Suppl.(Sys. 

 Fil. Foss.), 1836, p. 246. This is the Pseudopecopteris ob- 

 tusiloba (Brongniart) of Lesquereux: Second Geol. Surv. 

 Pa., Rept. Progr. P. (Coal Fl.), vol. 3, 1884, p. 753. D. 

 ^\'hite: Bull. Geol. Soc. Am., vol. 11, 1900, p. 170. [Cone- 

 maugh formation] . 



The report of the species by Fontaine (Amei. Jour. Sci. 

 (3), vol. 7, 1874, p. 574) from the Sewell formation is un- 

 doubtedly erroneous. It is probable that the Sewell plant is 

 close to, if not identical with, that described by Lesquereux 

 (Coal Flora, vol. 3, 1884, p. 770, pi. civ, figs. 2-4) as Eremop- 

 tcris Cheathami. 

 Cheilaxthites obtusilobus var. dilatata (Lesquereux). 



The Pseudopecopteris obtusiloba dilatata (Lesquereux) 

 Lacoe: Cat. Palaeoz. Pits. X. Amer., Pittston, 1884, p. 9. 

 D. \Miite : Bull. Geol. Soc. Am., vol. 11, 1900, p. 163. 

 [Pottsville group; Kanawha formation]. 

 Cheilanthites solidus D. White. 



This is the Sphenopteris solida of Lesquereux: Second 

 Geol. Surv. Pa., Rept. Progr. P, vol. 3, 1884, p. 759, pi. ci, 

 fig. 3. D. ^^'^hite: Bull. Geol. Soc. Am., vol. 11, 1900, p. 170. 

 [Pottsville proup ; Kanawha formation]. [Also in Cone- 

 maugh formation]. 

 Cheilaxthites squamosus (Lesquereux) D. White. 



Bull. Geol. Soc. Am., vol. 11, 1900, p. 170. This species, 

 first described by Lesquereux as Pecopteris squamosa, has 

 generally been recorded in the American literature as Pseu- 

 dopecopteris anceps. It is possibly indistinguishable from the 

 European plant known as Pecopteris sphenopteroides. [Alle- 

 ghen)- and Conemaugh formations] . 

 Cheilanthites cf. nummularius (Gutbier) D. White. 



This is the Pseudopecopteris cf. nuiiitnularia (Gutbier) of 

 Lesquereux: Second Geol. Surv. Pa., Rept. Progr. P, (Coal 

 FL), vol. 3, 1884, p. 751, pi. ciii, figs. 1-3. D. ^^'hite: Bull. 

 Geol. Soc. Am., vol. 11, 1900, p. 168. [Pottsville group; 

 Kanawha formation]. 

 DiPLOTHiiEMA FACHYDERMA (Fontaine & I. C. White) D. White. 



The Odontopteris pachyderma of Fontaine and I. C. 

 White: Second Geol. Surv." Pa., Rept. Prog. PP., 1880, p. 53, 

 pi. x. figs. 5-10. [Dunkard formation (Permian).]. 



DiPLOTHMEMA cf. JaCQUOTI ZeILLER.

 group : Kanawha formation.] 

 Mariopteris pottsvillea D. White. Twentieth Ann. Rept. U. 

 S. Geol. Surv. i898-'g9, pt. 2, 1906. 

 This is the plant listed as Pseudopecopteris muricata
