304 T. Davidson — Notes on Continental Geology. 



cient to mention tliat the Cephalopoda of this locality approach a 

 little nearer to the Neocomien type,, while the Echinoderms and the 

 Brachiopoda have somewhat more of a Jurassic aspect ; nevertheless 

 their resemblance to the former or the latter fauna is very slight. 

 Elsewhere the fauna of Stramberg is very intimately allied to that 

 of the breccia of the Klippenkalk by a number of identical or 

 analogous species ; so much so, indeed, that these beds ought, in 

 my opinion, to be united into a single stage, namely, the Tithonic, 

 of which they represent two horizons. The Stramberg limestone 

 corresponds exactly to the limestones with Ter. janitor of the Porte- 

 de-France, the breccia of the Klippenkalk to the white limestone 

 with Tereh. diphya of the centre of Italy, while the upper portion 

 of the ' Ammonitico Eosso ' of the Southern Tyrol represents those 

 two horizons in a single bed.

" In regard to the classification of the formations in question, 

 MM. Lory and Pictet have adopted the opinion expounded by 

 Oppel, who correlates them with the freshwater deposits of the 

 nortli-west of Europe, on the limits of the Cretaceous and Jurassic 

 formations. It, therefore, appears to me a question of secondary 

 importance, and more or less formal, whether the beds in question 

 are placed in the Jura or the Chalk, stating at the same time that 

 the Tithonic beds in the districts I have been able to visit, namely, 

 in the Southern Tyrol and Carpathians, are in closer connection 

 with the Jurassic than with the Neocomien deposits. I only insist, 

 however, on the re-union of these formations in a stage independent 

 alike of the Kimmerigian and the Neocomien, for which Oppel pro- 

 posed four years ago the name of Tithonic stage." 



Since the publication of the June number of the Geological 

 Magazine, Dr. U. Schloenbach, of the Imperial Museum of Vienna, 

 has kindly transmitted to me the following table and remarks, with 

 a request that they should be added to my Continental notes. 

 " Allow me to address to you, on this occasion, a few remarks on 

 the upper part of the Cretaceous formation (Planer of Prof. 

 Giimbel) in the countries where I have had the opportunity of 

 studying it myself — namely, the ancient province of Maine in 

 Western France, Northern France, Northwest Germany, Saxony, 

 and Bohemia, and the Northern and Western Calcareous zones of 

 the Eastern Alps in Austria. In the accompanying table (see 

 p. 306) I have attempted to exhibit my views on the parallelism of 

 the strata in those regions. In this table I have omitted our 

 Austrian Alps, as my opinion on the different strata developed
