to the Jura and Wealden than to the Chalk period. The following 

 additions are made to the species already included among the 

 plants from Ettingshausen's "Wealden localities 1 : 



Ch on d 'rites fur 'tillatus, Roem. 

 Eaiera cretosa, Sch. 

 Cycadopteris Dunkeri, Sch. 

 Oycadites Heerii, Sch. 

 Podozamites Zittelii, Sch. 



P. Hoheneggeri, Sch. 



P. obovatus, Sch. 



Zamites Gopperti, Sch., and four other 



species. 

 Widdringtonites gracilis, Heer ? 



In Yelenovsky's contributions to Mesozoic botany we have 

 certain species recorded from Lower Cretaceous rocks in Bohemia 

 which point to a close agreement in facies with the North German 

 and English Wealden. These beds are classed by Velenovsky as 

 Cenomanian. 2 Among the " Eerns " from Peruc and other 

 localities the following species occur, which are identical with or 

 closely allied to typical Wealden forms : 



Thyrsopteris capsulifera, Vel. 

 Laccopteris Dunkeri, Schenk=Jfic/o- 



dictyon Dunkeri (Schenk). 

 Ptsris frigida, Heer. 



P. Albertini (Dunk.) = ? Cladophlebis 



Albertsii (Dunk.). 

 Jeanpaulia earinata, Vel. 

 Dicksonia punctata (Sternb.). 

 Tempskya vanans (Corda). 



Among the Gymnosperms from the same beds there are certain 

 forms which closely resemble Wealden species 3 e.g. : 



TJiinnfeldia variabilis, Vel. =? 'Sageno- 



pteris Mantelli (Dunk.). 

 Nilssonia Bohemica, Vel. 

 Sequoia Reichenbachi, Heer. 



Cunninghamites elegans, Heer. 

 Pinus Quenstedti, Heer. 

 Eolirion primigenium, Sch. 



POETUGAL. 



In his " Contributions a la flore fossil du Portugal" Heer has 

 given descriptions and illustrations of the following species from 

 two localities Almargem and Yalle de Lobos; these floras are 

 considered by him to be in " intimate relation with the Wealden 

 flora." 4
