Here in the Kladno-Eakonitz Coal-basin the Gas-coal lies therefore 

 above the Coal-seam. The shale above the Gas-coal, however, con- 

 tains again a Flora which is very distinctly Carboniferous. 



1 enumerated it already on various occasions.' I will especially 

 note — Calamites SucJcowi, Brong. ; AsteropTiyllites, SpJienophyllum, 

 Cyatheites, Alethopteris, Caulopteris peltigera, Brong. ; ^ Lycopodites 

 selaginoides, Stbg. ; Lepidodendron dicliotomum, Stbg. ; Sigillaria 

 alternans, L. & H. ; S. Cortei, Stigmaria ficoides, etc. All these 

 occur therefore above the Permian Fauna, and no Permian plants 

 amongst them. 



h. The Bed Sandstone Formation. 



Above this Upper Coal-seam, with the Gas-coal on top, we find 

 tbe real Permian Series partly exposed near Eakonitz, but especially 

 more to the north, near Klobuk and Perutz, where they dip imder 

 Cretaceous beds, and extend to the valley of the Eger river, between 

 Postelberg and Budin, as they are seen in that region on the right 

 shore of that river. In this series we have again the Permian 

 Araucarites stems in abundance, as in the Pilsen Basin and in the 

 truly Permian strata in N.E. Bohemia, on the S.W. side of the 

 Eiesengebirge. 



From near Klobuk we know Calamites gigas, Brong., and WalcJiia 

 piniformis, Stbg., etc. The sequence of the beds in this Coal-field 

 is, therefore, generally the following : 

 1. Red Sandstones — With Araucarites, Calamites and Walchia.

 If we now compare both these basins (Pilsen and Kladno-Eakonitz) 

 we shall observe : 



1. The group of Eed Sandstones in the Kladno-Eakonitz basin is 

 equal to the same group in the Pilsen basin, with the beds near 

 Ledec and Zilow. 



2. The Eakonitz-Schlan Gas-coal is rather higher in the series 

 than the Gas-coal at Niirschan, though both contain some genera of 

 animals in common; the Flora being, however, much more abundant 

 near Niirschan than near Eakonitz, seems to indicate a slow ex- 

 tinction of it towards this latter place ; but this Eakonitz Gas-coal 

 was, even by Dionys Stur, acknowledged as Permian in his mis- 

 leading paper on that subject in Verh. d. k. k. geol. Eeichsanstalt, 

 Wien, 1874, p. 194. 



3. The lower seam in the Pilsen basin is of the same horizon, as 

 in the Kladno-Eakonitz basin. 



This we may perhaps explain in the following way :
