135. Portion of a very large rachial leaf, seven inches by 



four; the outline rather imperfect. The nervation distinct. 

 The nerves appear in double lines nearly parallel, and bifurcate 

 towards the outer margin of the leaf. 

 Loc. — Shale above the Low-Main Seam, Felling. {H. C. —). 



136. — Cyclopteris obliqua, L. et H. Type specimen, F. F., pi. 90b. 

 Large rachial pinna, with the outer margin imperfect, basal 

 part curved round to the left. Hutton label, " Cyclopteris 

 obliqua, Jarrow, Bm." 

 Loc— Shale above the Bensham Seam, Jarrow. (H C. 200). 



137. L. et H. Type specimen, F. F., pi. 90a. 



Very imperfect impression of large kidney-shaped pinna or 

 leaf ; the basal portion perfect, with sharp curve to the left. 

 Hutton label, " Cyclopteris obliqua, Jarrow, Bm." 

 Loc. — Shale above the Bensham Seam, Jarrow. (H,C. 199). 



138. Part of a large rachis or stem, with a pinna or leaf of 



Cyc. obliqua apparently attached to the rachis, which shews 

 these large specimens of Cyclopteris to be cauline or rachial 

 pinnge of one of the species of Neuropteris. On the same slab 

 are some good examples of Myriophyllites gracilis. 

 Loc. — Shale above the Low-Main Seam, Felling. (H.C. 201).

margin. Nervation distinct ; the nerves appear radiating in 

 bundles, and frequently bifurcate towards the upper, outer 

 margin. Hutton label, " Cyclopteris, Felling, L. M." 

 Loc. — Shale above the Low-Main Seam, Felling. (H. C. 198).
