GEOLOGICAL MEMOIRS. 



basin there are only a few, thin coal-seams ; bnt, on the other hand, 

 the thickly developed Rothliegende here contains some productive 

 coal-beds. It is to be hoped that the Rothliegende in this portion 

 of the basin, where it dips beneath the Cretaceous beds, will be still 

 further worked for coal. 



The Basin of Stradonitz, which is situated about two German 

 miles south of the south-eastern border of the Rakonitz Basin, in 

 the neighbourhood of Beraun, contains, so far as is known at pre- 

 sent, no coal-beds. The fossil Plants occurring in the sandstone and 

 shale have been described by Herr von Ettingshausen ; they are the 

 following : — 



Chondrites Goeppertianus, Ettingsh. 



(perhaps the root of a land-plant). 

 Calamites Volkmanni, Ettingsh. 

 Sphenophyllum Schlotheimi, Brongn. 

 Annularia longifolia, Brongn. 

 Neuropteris gigantea, Sternb. 



Loshii, Brongn. 



coriacea, Ettingsh. 



squarrosa, Ettingsh. (=Dictyo- 



pteris Brongniarti, Gutb.). 



Cyclopteris tenera, Ettingsh. 



rhomboidea, Ettingsh. 



Sphenopteris Haidingeri, Ettingsh. 



intermedia, Ettingsh. 



trifoliata, Brongn. 



Asplenites elegans, Ettingsh. 

 — — Reussi, Ettingsh. 

 Cardiocarpum orbiculare, Ettingsh. 

 Cordaites borassifolia, linger. 

 Palmacites caryotoides, Sternb. 



It is remarkable that this basin contains especially the remains of 

 Ferns, some of which correspond with those found in the upper beds 

 of Rakonitz. It is certain that those fossils are not found at any 

 other locality in Bohemia, and are unknown from other coal-fields. 



Prom Kladno, in the Basin of Buschtiehrad, the author obtained 

 the following plants : — 



Calamites communis, Ettingsh. 



tenuifolius, Ettingsh. 



Sphenophyllum Schlotheimi, Brongn. 

 Neuropteris acutifolia, Brongn. 



rubescens, Sternb. 



obovata, Sternb. 



Sphenopteris meifolia, Sternb. 



acutifolia, Brongn. 



tenuissima, Sternb. 



obtusiloba, Brongn. 



elegans, Brongn. 



rutsefolia, Gutb. 



Cordaites borassifolia, Unger. 

 Asplenites Sternbergi, Ettingsh. 



lindsasoides, Ettingsh. 



Cyatheites oreopteroides, Goepp. 



Cyatheites undulatus, Goepp. 



setosus, Ettingsh. 



Pecopteris pennasformis, Brongn. 



Glockerana, Goepp. 



Lepidodendron dichotomum, Sternb. 



aculeatum, Sternb. 



Sternbergi, Lindl. 



brevifolium, Ettingsh. 



plumarium, Lindl. 



Haidingeri, Ettingsh. 



crassifolium, Ettingsh. 



Sigillaria elongata, Brongn. 



rhomboidea, Gein. 



mammillaris, Brongn. 



Stigmaria ficoides, Brongn. 

 Araucaria Cordai, Sternb. 



According to Herr Stur, the following species also occur : — 



Cyatheites arborescens, Goepp. Pecopteris Silesiaca, Goepp. 

 Miltoni, Goepp. 



The flora of this basin corresponds in general with that of the 

 Basin of Radnitz. Some short lists of Plants found at other loca- 

 lities in the Basin of Buschtiehrad are then given ; the most im- 

 portant of these lists are the following, of Plants occurring in the 

 roofs of two coal-beds worked in the Rappiz (Hrapic) district, and 

 near Buschtiehrad, as well as near Wotowitz and Koletz.
