Neuropteris crenulata ? ' Brgt. Lesq. Geol. Pa. 1858, p. 



859, pi. 5, fig. 6 ; one single leaf of this 

 J^^' European fern, found by Lesquereux at 



the Anthracite Salem vein, Pottsville ; 



but its nervation and very small round 



teeth around the leaf identified it. 



Also, Coal Flora, 1880, p. 116, pi. 16, 

 figs. 9 to 11. Specimens from Wilkesbarre, and from the Tre- 

 mont tunnel vein, throw doubt on the identity. (Lesq.) A few 

 specimens at Cannelton, W. Pa. — XIII.
