412 J. FE. Marr—Paleozoic Rocks of Hof, Bavaria. 
between the beds of the two areas, and in some respects this is the 
case, though the marked differences induced Barrande to infer the 
existence of a barrier between the two areas in Lower Paleozoic 
times. ‘The differences may be accounted for in other ways; firstly, 
by the absence of some beds in Bohemia owing to unconformable 
overlap, and in Bavaria owing to faults, and secondly by the greater 
metamorphism of the Bavarian rocks. The effects of the latter have 
been described by Prof. Giimbel; the Cambrian beds are frequently 
converted into schists, the Ordovician into phyllites, and the Silurian 
into lydites, whilst the associated igneous rocks have also suffered 
much change, indeed the Fichtelgebirge furnish us with an admirable 
instance of later rocks having undergone regional metamorphism, 
and being infolded amongst other rocks which have been universally 
assigned to the Archean. 
Commencing with the Cambrian Rocks, the only fossils found in 
them are of very doubtful position, amongst these is Phycodes 
circinatum, which characterises the Phycodenschichten. The rocks 
are various coloured clay slates, and greywackes, sometimes converted 
into schists, as at Lamitzmiihle, north-west of Hof, where the 
development of the schistose structure is admirably exhibited. Red 
beds are seen between Hof and Leimitz, and like similar Bohemian 
beds are possibly very low in the Cambrian system. 
In the typical section at Leimitz the above-described beds are 
separated from the trilobitic shales of Leimitz by a dolomitic lime- 
stone; this is very possibly developed along a fault-plane, and 
would account for the apparent absence of the representatives of 
the Menevian and Lingula Flag series. The country here is so 
extremely faulted that rocks of very different ages are brought into 
juxtaposition. Not only are all the beds in the Leimitz section 
reversed, as shown in Murchison’s section from the Labyrinthen- 
berg to the Wartthurm (Q.J.G.S. 1863, p. 860); but it can be 
shown that in several places beds are faulted out, and the failure to 
discover Menevian and Lingula Flag fossils must not be taken as 
an indication of the original absence here of beds of these ages. 
The next beds to notice, in ascending order, are the Leimitz- 
schichten, though there is no necessity to linger over these, as not 
only has Barrande fully described the fauna (“ Faune silurienne des 
Environs de Hof en Baviére,” 1868), but Prof. Brogger has shown their 
close relationship with the Ceratopyge beds of Scandinavi a, and the 
Shineton Shales of Shropshire (‘ Die silurischen Etagen 2 und 3”’). 
In the Leuchtholz, near Lamitzmiihle, is a gritty pisolitic iron- 
stone, containing an Orthis compared by Dr. Gtimbel with Orthis 
Lindstremi, Linnrs., whilst the rock containing it is referred to as 
possibly comparable with the Primordial beds. Concerning this 
deposit I would say something further. It occurs between the 
schistose Cambrian rocks of Lamitzmihle, and black phyllites and 
grey gritty shales near the village of Isaar. The latter are coloured 
in Dr. Giimbel’s map with the Ordovician (Lower Silurian) colour, 
and though much altered they bear considerable resemblance to the 
beds of Barrande’s étage D. Now, near the base of D, in Bohemia 
are found the pisolitic ironstones, Dd 1, containing Orthis deside-
