CHEILANTHITES 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., Kept. Progr. P. (Coal Fl.), vol. 3, 1884, p. 753. D. 

 White: Bull. Geol. Soc. Am., vol. u, 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 Eremap- 

 teris Cheathami. 



CHEILANTHITES OBTUSILOBUS VAR. DILATATA (Lesquereux). 



The Pseudopecopteris obtusiloba dilatata (Lesquereux) 

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

 D. White: Bull. Geol. Soc. Am., vol. n, 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. White: Bull. Geol. Soc. Am., vol. u, 1900, p. 170. 

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

 maugh formation] . 



CHEILANTHITES SQUAMOSUS (Lesquereux) D. White. 



. Bull. Geol. Soc. Am., vol. n, 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- 

 gheny and Conemaugh formations] . 



CHEILANTHITES cf. NUMMULARIUS (Gutbier) D. White. 



This is the Pseudopecopteris cf. nummularia (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. n, 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. JACQUOTI ZEILLER. 



Bull. Geol. Soc. Am., vol. n, 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 Pseudopecopteris muricata
