J. E. Marr— Paleozoic Rocks of Hof, Bavaria. 413 
vata, Barr., seen at Krus’na Hora and elsewhere, and actually com- 
pared by Dr. Giimbel with the Leuchtholz ironstone. The latter 
I was unable to find im situ, but Herr Glass kindly presented me 
with specimens, and the Orthis, though badly preserved, is very 
near to, if not identical with Orthis Rea deaee with which I have 
compared it. The reasons for the identity of the Bavarian and 
Bohemian deposits are similarity of lithological characters, close 
resemblance between the Orthides of the two, and the occurrence 
of both between Cambrian and Ordovician deposits. 
In a paper read before the Geological Society (Q.J.G.S. 1880) 
I correlated the beds Dd 1 with Tremadoc beds, on account of 
their resemblance to the pisolitic ironstones of North Wales, their 
occurrence above sandstones full of Zingula Feistmantelh, and the 
existence of Harpides Grimmi in them. I believe, notwithstanding 
the occurrence of the latter fossil, that the reference was erroneous. 
The Tremadoc age of the Welsh pisolitic ironstones has not been 
proved, indeed evidence has been published which indicates that 
they are much more modern. With regard to the occurrence of 
Lingula Feistmanteli in Dd 1 a, this fossil has no relationship with 
any of the Lingula Flag fossils, but it is very near to the remarkable 
Lingulad Roualti of the Armorican grits. Furthermore, the fauna of 
Dd1lvy is not a Lower but an Upper Arenig one, and the beds of 
this band immediately and conformably succeed those of Dd 1 £. 
I am inclined therefore to refer the latter, and with it possibly the 
Leuchtholz deposit to a position high up in the Arenig series, and 
believe that the beds unconformably overlap the Cambrian rocks, 
thus accounting for the absence of Lower Arenigs in Bohemia and 
Bavaria, of Tremadocs and Lingula Flags in the former country, and 
of Menevians around a great part of the Bohemian basin. 
We visited Hof, partly in hopes of detecting Graptolites of Hartfell 
and Glenkiln types in the Ordovician rocks; in this we were 
disappointed, nor did we find any trace of such fossils in Herr 
Glass’s collection or in that of the Dresden Museum. I believe 
however that there are black shales of Ordovician age which have 
once contained Graptolites (e.g. the phyllites near Isaar) but with 
rocks so greatly altered. it is too much to expect their preservation. 
Though rocks of the higher Ordovicians do probably occur in 
many places, they are elsewhere faulted out, as for instance at 
Leimitz, where the Lower Graptolite Shales are directly in contact 
with the Leimitz trilobitic shales. The former are here converted 
into lydite, but a few obscure graptolites were seen by us. Clinaco- 
graptus normalis was found here by Herr Glass, and the beds are 
undoubtedly the equivalents of our Stockdale Shales. In most of 
the localities near Hof these shales are now covered up, but in the 
Dresden Museum is preserved a slab from Teufelsberg with Petalo- 
graptus palmeus and Monograptus Hisingeri, indicating the Upper 
Skelgill beds, and Prof. Nicholson and myself have already recorded 
the existence of two slabs in the Woodwardian Museum indicating 
the existence of the Monograptus fimbriatus zone at Hof, whilst Herr 
Glass has M. turriculatus and M. rectus from Steben.
