112 Br. Feistmantel — Boliemian Coat Fauna and Passage- Beds. 
Mining is carried on there to a great extent,, and there are several 
localities where fossils can be got. The fossils throughout are plants 
of Oarboniferous character ; and sonie remains of a Scorpion were 
procured, which were ranged by Dr. Fritsch with Cyclophthalmus 
senior, Corda. 1 
Of tbe plant remains, I described those from Kralup in a special 
paper, 2 and the others I enumerated in my general paper on tbe Coal- 
basin. 3 
All Orders of Oarboniferous plants are represented, and some Clay- 
bands in the Coal-seam are especially rieh in plants. 
For the comparison of this seam with others in Bohemia, the 
abundant occurrence of the genus NöggeratMa is very useful; 4 
two species are found : NöggeratMa foliosa, Stbg., and NöggeratMa 
intermedia, K. Feistm. This species, however, Mr. Stur, of Vienna, 
considers as belonging to the genus Bhacoptens, Schitnp. Cer- 
tainly these forms have nothing in common, and this Nögg. inter- 
media, K. Feistm., at Rakonitz, is a true Nöggerathia. Besides the 
foliage, there occurred also a fruit of NöggeratMa, which I called 
NöggeratMaestrobus bohemicus, 0. Feistm. 
The Upper Coal-seam District. 
This overlies conformably the Lower Coal-seam District, extends 
in a northern direction, and is especially developed in the neighbour- 
hood of Rakonitz, near the Zbanberg at the villages Mutiowitz, 
Kounowa, Hredl, etc., and in the neighbourhood of Sehlan, at Stern, 
Libowitz, Lotausch, etc. 
The Coal-seam in this district is only about metres thick, but is 
immediately overlain by the Gas-coal, about 8 to 11 c.m. thick, locally 
called Schwarte ; above this we again find sliales. 
The Gas-coal here is of the same importance as the Niirschan Gas- 
coal in the Pilsen Basin ; it contains the animal-remains. These were 
very distinctly mentioned already by Messrs. Reuss 5 and Lipoid 6 in 
their papers on the geological relations of these Coal-basins ; they 
are, as far as at present known : CtenoptycMus brevis, Rss. ; Desmodus, 
sp. ; Palceoniscus Vratislaviensis, Ag. ; Acanthodes gracilis, Röm. ; 
Xenacanthus Decheni, Beyr. ; Diplodus ; Pygopterus, sp., etc. 
From this both Reuss and Lipoid drew the conclusion that this 
Gas-coal should be considered as Permian, and also Dionys Stur 
regards this Gas-coal (bis Kounowa Series), as being of Permian age, 
while the Nürschan Gas-coal, containing many more forms of that 
kind, he puts down as the lowest portion of the Carboniferous. 7

from these beds.
