ing line blue carbonate of copper, with some coaly matter, and 

 footprints of small Hep tiles in the accompanying shale. Copper- 

 works were formerly in activity here. It is in the extension of these 

 shale-beds that the best Reptilian footprints have been obtained at 

 Kalsia, near Hohcnelbe. 



11. Argillaceous beds, becoming more sandy downwards. These 

 occupy a considerable thickness, and are exposed in partial undula- 

 tions. On the whole, however, they rise to the N.W., and are asso- 

 ciated with much melaphyr (amygdaloid^) and thin-bedded basalt 

 or clinkstone, which is exposed in great tabular masses in the hill 

 called Pansko, and are accompanied by hardened sandstone and 

 shale ; the whole dipping away to the S.E., from Semil and the 

 valley of the Iser. 



12. Reddish glossy shale, and thin courses of grit, with ripple- 

 marked surfaces and many Plants (Calamites and Ferns), alter- 

 nating with bluish-grey beds. In a dark, papyraceous, leather-like 

 schist are the lowest Fish-remains, Palaeoniscus, &c. ; and the section, 

 as terminated in a north escarpment on the river Iser, exhibits at its 

 base sandstone and grit, which are succeeded by 



13. The bottom- rock of the series. This consists of coarse con- 

 glomerates of water-worn and well-rounded pebbles of the older crys- 

 talline rocks of the Riesengebirge, which, alternating with bands of 

 coarse gritty sandstone, are well seen to the north of Semil. These 

 beds, of very great thickness, dip under and support all the before- 

 mentioned succession, and rest in their turn on the subcrystalline, 

 Palaeozoic, or metamorphic rocks of the Riesengebirge*. 



Organic Remains. — In his excellent new work, ' Dyas ' (to the 

 name only of which I demur), Professor Geinitz describes the follow- 

 ing organic remains as belonging to the Roth-todt-liegende, or his 

 Lower Dyas. A large portion of these fossils occur in Bohemia, and 

 many species are common to the same rocks in Saxony, Bohemia, 

 Russia, and other tracts : — 



SaURIANS IN THE RoTH-LIEGENDE. LOCALITIES. 



Sphenosaurus Sternberg!, V. Meyer ... Konigratz, Bohemia.

 in the Kupferschiefer two only, the Protorosaurus and Parasaitrus, are known. 



* M. Porth estimates these lower beds as being 000 feet thick.
