Lartington. Though Sternberg's Type figure is undecipherable, 

 yet no one can doubt that the figure given by Brongniart is 

 identically the same species as S. affinis, L. et H., and is probably 

 from the Calciferous Sandstone series of Edinburgh.]

94. — Sphenopteris Artemisicefolia. (Sphenopte?-is sp. Lebour, 111. Foss. 



Pits., pi. 36). Type. 

 Terminal portion of a frond, in a fine state of preservation, 

 shews the shape and nervation of pinnules distinctly. The 

 pinnules branch off on each side and slightly bifurcate ; leaves 

 or pinnules taper gradually to a point, are not so inversely 

 wedge-shaped as in var. Crithmifolia, nor so regularly split 

 up ; the nervations of the leaves are also more regular. 



Loc— Shale above the High-Main Seam, Fawdon. (H. C. 631). 



95. {Sphenopteris sp. Lebour, 111. Foss. Pits., pi. 28). Type. 



Frond, with very straight flattened stem, shewing the branches 

 sometimes nearly opposite, at other parts, alternate ; pinnules 

 regularly fissured on each side, and the impressions of the 

 nerves distinct. 



Loc— Shale above the High-Main Seam, Gosforth ? {B. C. 192).
