have successively occupied the surface of the Earth. 361 



impressions from whence M. linger has so well made known in 

 his 'Chloris protogsea/ and which have become almost the type of 

 the pliocene flora. 



With the exception of the lignite beds of the environs of Cassel 

 and Frankfort, the species of which often have numerous relations 

 with those of (Eningen and Parschlug, and which perhaps belong 

 rather to the pliocene flora, the diff'erent localities which I have 

 just cited have many relations in respect to their fossil plants. 

 Thus the Nymphcea Arethusa occurs in the millstones of Paris 

 and in the marls of Armissan ; the Flabellaria rhapifolia and 

 maxima occur at Horing in Tyrol, at Radoboj in Croatia, and in 

 the upper sands of the environs of Angers and Perigueux. The 

 Callitrites Brongniartii, Endl., occurs equally in the beds of Ai'- 

 raissan, of Aix in Provence, of Horing, and of Radoboj. 



Lastly, the Steinhauera ylobosa of the lignites of Altsattel in 

 Bohemia, occurs also in the sands of the environs of Mans, and 

 the Platanus Hercules of Radoboj in Croatia has been sent to me 

 from Armissan, by M. Tournal. 



These facts will probably be multiplied by a more attentive 

 study of the diff'erent localities, but they already leave little doubt 

 about the synchronism of the majority of these local formations.
