DESCKIPTION OF SPECIES. PP. 103 



though enough of the leaf is preserved in some specimens to 

 show pretty clearly what must have been its shape. Fig. 

 11, PI. II, represents a small fragment of a plant which 

 may be different from S. salisburioides, as its texture is thin- 

 ner, and the fragments found associated with the pieces 

 depicted indicate a leaf of larger size. The fragments are 

 too small to give us any indication of the shape of the en- 

 tire leaf. They may belong to S. salisburioides in a more 

 advanced stage of growth of the leaf. Plate XXXVIII, 

 Fig. 2, represents a larger fragment, to which also the 

 above remarks may apply. 



Habitat. — Roof shales of the Waynesburg Coal, Cass- 

 ville, W. Ya, 



Baiera, (Fr. Braun,) emend. Heer. 



We follow Heer, in his emendation of the generic char- 

 acter of Baiera, in which he sejDarates it from Salisburia (Cy- 

 clopteris,) and unites it with Jeanpaulia. 



Baiera Virginiana. Sp. nov., PI. XXXVII, Figs. 11, 12. 



(Leaf, llabellate, divided into numerous lacinige towards 

 the summit, and narrowing into a wedge shape towards 

 the base, undivided for some distance above the base ; 

 lacinise, slowly diverging, and each forking dichotomously 

 once or twice, divisions strap-shaped and truncate ; leaf- 

 substance, thick and leathery ; nerves, several in each 

 lacinia, strongly marked, forking once or twice, and pro- 

 ceeding parallel to each other.) 



The plant has never been seen entire. Fig. 12 repre- 

 sents the most perfect specimen ; Fig. 11 gives a fragment 

 showing more numerous and delicate lacinise. This plant, 

 in its robust character and thick leaf substance, has much 

 resemblance to Baiera longifolia (Jeanpaulia) Heer, of the 

 Jurassic, given in Vol. IV, Foss. Flor. Arct. PI. IX, Figs. 

 1-11. It is very nearly allied to B. digitata, Heer, figured 

 by Geinitz in his Dyas, PI. XXVI, Fig. 2, under the name 

 of Zonarites digUatns, Brongt.
