380 W. M. Fontaine— Conglomerate Series of West Virginia. 

 resembles somewhat that of a Neuropteris in the fact that the 



vation is like that of No. 7, but in the insertion of the pin- 

 nules by the entire base, in their decurrence, and other points, 

 this is a true Akthopteris. 



12. Nenropteris Liiulkyana Sternb. Var. This beautiful Neu- 

 ropteris is common at Sewell Station, where it forms the only 

 plant found at the horizon of coal 5. It also occurs with 

 this coal, in the Piney Eiver section, on the Ealeigh road. 

 While in the main point it clearly resembles N. Lmdleyana^ 

 figured in the Fossil Flora of Great Britain, as N. Loschi, there 

 are some points of difference. Our plant has not the same degree 

 of sharpness in the terminations of the upper simple pinnae, and 

 these are not so much narrowed at the base. Again the 

 rounded pinnules of the lower compound pinnae have a much 

 more slender midrib than that indicated in the figure of the 

 British plant. They are also more closely placed, in the 

 greater bluntness of the upper simple pinnsG, and in their nearer 

 approach to a heart-shaped base, this plant approaches nearer to 

 N. Loschi, but it is very different, and may perhaps be best 

 considered as a variety of N. Lindleyana. 



13. Neuropteris tenuifolia Schloth. Found with coal 6 on the 

 Ealeigh road, apparently rare. 



14. Sphmopteris, species? This plant was found with coal 5 

 on the Ealeigh road. The fragments found do not enable me to 

 determine it satisfactorily. It belongs to the Schimpers sec- 

 tion, Sphenoptf^is cheilanthides. It is in some respects like S. 

 Duhmssonis, but differs in others. The following features are 

 shown in the fragments obtained: Pinnae oval lanceolate, 

 placed alternately at right angles on the rachis. Pinnules 

 obliquely and alternately placed on the secondary rachis which 

 at the base is narrowly winged and from which they diverge: 

 oblong, narrowing considerably to the summit, and slightly so at 

 the insertion of the base, where they are decurrent. The pinnules 

 diminish rapidly in size from the base to the apex of the pinnae. 

 At the base they are one era. long and four mm. wide. The 

 pinnules of the base of the pinnae are cut obliquely into three 

 oval tooth-shaped lobes on a side, which are remotely placed, 

 and diverge slightly from the midrib. In ascending, the num- 

 ber of the lobes and the depth of their incision diminishes 

 until the pinnules become entire, when they are very small 

 and mere lobes of the wing of the rachis, which at the extrem- 

 ity of the pinnae is much widened. The plant seems to have 

 leaflets of leather-like consistency; the nervation is obscure 



15. Spheiwpteris, species ? This plant, which is not uncommon 

 with coal 6 on the Ealeigh road, has a strong resemblance to
