Cheilanthites obtusilobus (Brongniart) Goeppert 



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

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

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

 Pa., Kept. Progr. P. (Coal FL), vol. 3, 1884, p. 753. D. 

 White: 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. 



Cheilanthites obtusilobus var. dilatata (Lesquereux). 



The Pseudopecoptcris obtusiloba dilatata (Lesquereux) 

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

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

 [Pottsville group; Kanawha formation]. 



Cheilanthites solidus D. White. 



This is the Sphcnopteris solida of Lesquereux : Second 

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

 fig. 3. D. White: Bull. Geol. Soc. Am., vol. 11, 1900, p. 170. 

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

 maugh formation] . 



Cheilanthites souamosus (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- 

 dopecoptcris anceps. It is possibly indistinguishable from the 

 European plant known as Pecopteris sphenopteroides. [Alle- 

 gheny and Conemaugh formations] . 



Cheilanthites cf. nummularius (Gutbier) D. White. 



This is the Pseudopccopteris cf. nuiniindaria (Gutbier) of 

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

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

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

 Kanawha formation]. 



Diplothmema pachyderm a (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. Jacouoti Zeiller. 



Bull. Geol. Soc. Am., vol. 11, 1900, p. 163. [Pottsville 

 group : Kanawha formation.] 



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

 S. Geol. Surv. i898-'99, pt. 2, 1906. 



This is the plant listed as Pseudopccopteris muricata
