Thus, while nine species of Palceoniscus occur in the so-called 

 ' Roth-liegende,' seven other species of the same genus occur in the 

 Kupferschiefer or marl-slate at the base of the Zechstein. Is the 

 one set to be considered of marine, and the other of freshwater 

 origin ? or may they not all be of estuarine characters ? 



The north-eastern part of Bohemia is characterized by an abun- 

 dance of the stems of the large silicified fossil trees, Araucarites. 

 In former communications I have alluded to the great abundance of 

 this plant in the escarpments of the Lower Permian rocks south of 

 the Harz*. Again, at Radowenz, to the west of Braunau, in 

 Bohemia, I have alluded to its occurrence f. At the last-mentioned 

 locality, and also at Peckau, which lies a little to the west of the 

 line of section just described, the bed of indurated sandstone 

 in which these great plants are included being at the surface, 

 and nearly horizontal, the huge stems are seen to be spread over 

 several acres of land. A large collection of these is to be seen at the 

 seat of the Prince Lippe-Schoenburg. They are indeed common in 

 many museums ; and one of the largest specimens with which I am 

 acquainted, measuring 5| feet in diameter, was pointed out to me in 

 the Zwinger, at Dresden, by Dr. Geinitz. 



Referring to the description of the Permian plants by Dr. Gbppert, 

 I would remind my associates that this eminent botanist has shown 

 that, as a whole, they contain about eight per cent, of Carboniferous 

 species of plants J. Dr. Geinitz has also come to the same conclu- 

 sion. Now, independently of the clear order of superposition which 

 the Upper Carboniferous strata bear to the lowest division of the 

 Permian, or bottom-beds of the Roth-todt-liegende, any one exa- 

 mining the public collection at Dresden at once sees that the
