Thus F, G, and H, in Kaysek's conception the equivalent of the 

 Hartz Hercynian, were regarded as possessing a far more extensive 

 and general Devonian character, capable of subdivision; and in a 

 secondary sense the value of the term Hercynian was broadened, until 

 from having a local value in the expression of an earliest Devonian 

 fauna, it had come to be an equivalent (as far as concerned Bohemia) 

 for nearly the entire Devonian system. Still the suggestion could not 

 affect the proper conception of the Hercynian as a lowest Devonian 

 fauna, but was of much importance as an effort to ascertain the exact 

 equivalences in the great succession of calcareous faunas in Bohemia. 



In 1887, Frech published a memoir of great interest on the Palaeo- 

 zoic formations of Cabrieres in Languedoc,* a palaeozoic " oasis " which 

 had previously received cursory attention from Fournet, Graff, 

 De Bouville, Tromelin and Grasset, Barrois and von Koenen. The 

 series of deposits represented by the various profiles given extends 

 from the Amorican grits (considered the limital formation between 

 Primordial and Silurian) to the Carboniferous limestone. The upper- 

 most faunas of the Lower-Silurian and the oldest of the Upper-Silurian 

 appear to be wanting. The later Upper-Silurian is paralleled w r ith 

 the etage E a on the basis of the identification of a number of Bohemian 

 species. The Lower-Devonian lacks the earliest fauna (regarded as 

 the equivalent of F t ); that of the white limestone of the Pic de 

 Cabrieres is considered as essentially the equivalent of F 2 (Konie- 

 prusian), while the silicious limestone of Bissounel with interlaminated 

 coral banks, is the parallel of G r The Middle-Devonian faunas in the 

 Val dTsarne, the shales of Ballerades and Bataille, are regarded as 

 homologues of the zone3 G 2 , G 8 , and H respectively, while H is con- 

 sidered as possibly represented in the lower and middle elements of 

 the Upper-Devonian. 



Again, the same author, in 1888, in a remarkable series of investi- 

 gations on the palaeozoic of the eastern Alps in Styria and Carinthia,t 

 which had previously been studied by Stur, Clar, Stache and Hoernes, 

 reiterated with amplification, his proposed subdivision of the Bohemian 

 upper Stages. 



In the Carinthian Alps, the succession presented in the western sec- 

 tion in the Wolayer Thorl and the Plocken, and in the eastern section 

 at Osternigg, the representative of E 2 (Upper-Silurian) divides itself 

 into three zones: (1) that of Orthoceras potens and other species, Encri-
