PL xlv. Sphenopteris affinis, L. and H. 



Locality. — Limestone Quarries near Gilmerton, near 

 Edinburgh. 



Horizon. — Calciferous Sandstone Series. 



Bemarks. — From the structure of the fructification of this 

 species, it is now removed from Sphenopteris and placed in 

 Calymmatotheca, Stur. Full references to the literature of 

 the species are given elsewhere.^ 



PL xlvi. Sphenopteris crithmifolia, L. and H. 

 Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. Eoof of Bensham Seam. 



Bemarks. — I believe this species to be only a varietal 



form of Eremopteris (Sphenopteris) artemisi.^folia, Sternb. 



PL xlvii. Sphenopteris dilatata, L. and H. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. Eoof of Bensham Seam. 



Bemarks. — This may perhaps be referable to the Sphenop- 

 teris TRIFOLIATA, Artis sp. The species of this group are 

 closely related to each other, and it is almost impossible to 

 determine the true specific position of this specimen without 

 an examination of the type, which appears to be lost. 



PL xlviii. Sphenopteris caudata, L. and H. 



Locality. — (?) Jarrow Colliery. 



Horizon. — (?) Lower Coal-Measures. lioof of Bensham 

 Seam. 



Bemarks. — This is referable to Dactylotheca (Filicites) 

 PLUMOSA, Artis. There exists some doubt as to the specimen 

 having come from Jarrow, and therefore this record cannot 

 be relied on as far as the distribution of the species is 

 concerned. 



PL xlix. Neuropteris Loshii. 



Locality. — Felling Colliery. 

 Horizon. — Lower Coal-Measures. 



1 Trans. Roy. Soc. Edin., vol. xxxiii., p. 145. Owing to communications 

 I have lately had with Dr Nathorst, it appears that Sphenopteris frigida, 

 Heer, and Splienopteris ficxilis, Heer, do not belong to this species. The 

 figures of these i)lants are not very accurate.
