INTRODUCTION. XXI 



In addition to these there are three species recorded from 

 Langenberg near Quedlinburg l : 



Weichselia Ludovicee, Stiehler = W. Mantelli (Brong ) . 

 Pterophyllum Ernestine, Stiehler. 

 Pandanus Similda, Stiehler. 



In a recent communication from Struckmann 2 on the strata 

 between the "Hilsthon" and "Wealden of North Germany, it 

 is pointed out that in England the brackish water-deposits at 

 the end of the Jurassic period seem to have continued for a 

 longer time than in North Germany ; and this author suggests 

 that the Wealden should be regarded not as a distinct formation, 

 but as a facies, consisting of brackish water-deposits at the close 

 of the Jurassic period, and which, in some places, extended to 

 the Chalk. 



AUSTRIA. 



Ettingshausen in 1852 described a number of fossil plants from 

 Zobing and a few other localities, from beds considered to be of 

 "Wealden age ; many of the species being identical with "Wealden 

 plants of Northern Germany. The following species are recorded 

 from these plant-bearing beds 3 : 



Confervites setaceus, Ett. 



Sargassites Partschii, Ett. 



Sphcerococites chondri&formis, Ett. 



Equisetites Burchardti, Dunk. 



Cyclopteris squamata, Ett. 



C. Mantelli, Dunk. = ? Sagenopteris 

 Mantelli (Dunk.). 



Sphenopteris Mantelli, Brong. = Ony- 

 chiopsis Mantelli (Brong.). 



Alethopteris recentior, Ett. = ? Weich- 

 selia Mantelli (Brong.). 



Tceniopleris Zobingiana, Ett. = ? Frag- 

 ment of Neuropteris. 

 Cycadites Brongniarti, Roem. 

 Pterophyllum Buchianum, Ett. 

 P. nervosum, Ett. 

 Culmites prisons, Ett. 

 Thuites Hoheneggeri, Ett. 

 Araucarites Dunkeri, Ett. 

 A. curvifolius, Ett. 

 Carpolithes Lindleyanus, Dunk. 

 G. rostellatus, Ett. 



In 1871 Schenk discusses the plants and geologic age of the 

 "Wernsdorfer beds at some length; from an examination of the 

 flora he concludes that these Carpathian rocks are nearer in age
