165.— Sphenopteris caudata, L. etH. Type specimen, F.F., pi. 138. 

 Portion of frond, shewing numerous pinna? in a good state of 

 preservation. Identical with Brongniart's Pecopteris acuta. 

 Labelled " Sph. caudata," but not Hutton's writing. The 

 locality is very doubtful. 



Loc. — Shale above the Bensham Seam, Jarrow? (H.C. 643). 



166. L. et H. Type specimen, F. F., pi. 48. 



Fragments of two pinna? on a large slab of very fine non -mi- 

 caceous shale. Hutton's label, " Sphenopteris caudata, Jarrow, 

 B. P. 48." From the fineness of the shale one must doubt the 

 correctness of the locality. Shale like No. 169. 



Loc. — Shale above the Bensham Seam, Jarrow? (H.C. 642). 



167.— Pecopteris dentata, L. et H. Type specimen, F. F., pi. 154. 



Small frond, with numerous well-preserved pinna? ; the pin- 

 nules shew slight indentations on the margins. It must be a 

 very doubtful Jarrow specimen. Hutton's label, "Jarrow, H." 



Loc. — Somewhat doubtful, though labelled " High-Main 

 Seam, Jarrow. (H. C. — ). 



168. (Pecopteris serra? Lebour, 111. Foss. Pits., pi. 23). Type. 



Small portion of a frond, with numerous pinna? ; the pinnules 

 well preserved, and nervation distinct. 

 Loc— Uncertain. (H. C. 655).
