Br. A, Fritsch — Coal-fauna of Bohemia. 



however, as still incomplete, but he publishes the preliminary re- 

 sults, on account of the great interest which attaches, at the present 

 moment to the question of the probable age of these deposits. 



Vegetable remains from the Coal-shales are somewhat rare. But 

 large OarpoZi^Aesandpyritized stems of Psarowms have been obtained, 

 which require a more detailed examination before they can be de- 

 scribed. 



From the subjoined synopsis it appears that the locality of Nyran 

 furnishes twenty species, that of Kounova thirty species of animal 

 remains ; only five species are common to both localities. 



In the Permian of Bohemia only four of these occur (see the 

 table) . 



In comparing the Coal-measures of Bohemia with those of Saar- 

 bruch, Ehenish Prussia, only a few of the species appear to be 

 common to both, namely Acanthodes, Palceoniscus, and Gampsonychus ; 

 whilst Amblypterus is absent, and the ArchcBgosaurus of Lebach, 

 Ehenish Prussia, is represented in Bohemia by a distinct type. Dr. 

 Fritsch, however, does not consider his researches sufficiently com- 

 plete at present to decide the relative age of these deposits.
