T. Davidson— Notes on Continental Geology. 303 



In connection with the subject under discussion, Dr. M. Neumayr 

 favours me with the following statement (Vienna, June 5) : — " Sir, 

 Having read in the June number of the Geological Magazine two 

 notes ' communicated to you by MM. Lory and Pictet, in reference 

 to the classification of the beds with Terebratula diphya, wherein the 

 close affinity of the limestone of the Porte-de-France with those of 

 Stramberg, and with the Klippenkalk of the Carpathians are several 

 times pointed out, I think it will not be uninteresting for you to 

 record a few additional notes on the position of these beds which, 

 in the Carpathians, constitute the Tithonic stage. I therefore send 

 you a few lines relating to these formations, which I studied for 

 nearly three months last year. 



" There are in the Carpathians two parallel bands, each of them 

 more than a hundred English miles in length, and in width rarely 

 exceeding one mile, covered by a great number of ridges or reefs of 

 Jurassic and Tithonic limestones, which pierce in discordant order 

 the Neocomien marls. A great number of the reefs ('Klippen') in 

 the northern band are composed of the Stramberg limestone, while 

 that rock is very seldom found in the southern band, but, on the 

 contrary, there is an abundance of the Klippenkalk (calcaire des 

 recifs), a denomination which has not a very precise signification, 

 and under which are united or combined various beds of very dif- 

 ferent age. Nevertheless I succeeded in finding the Stramberg 

 limestone in two localities in this southern band, and in one of 

 them the superposition of this bed on the most recent portion of the 

 Klippenkalk (the breccia with Ter. Catulloi or diphya,) is very dis- 

 tinctly observed. 



"The beds of the Klippenkalk, which are connected with the ques- 

 tion at issue, consist here, at their base, of a red nodular limestone, 

 containing a fauna corresponding pretty nearly to the one with 

 Ammonites tenuilobatus, said to be Oxfordian by M. Lory, which is 

 found at the bottom of the beds with Ter. janitor at the Porte-de 

 Trance, and which should be placed according to another opinion in 

 the Kimmeridgian stage. In the upper beds of the reddish lime- 

 stone are found already intermingled with the fossils of the first 

 horizon the Ter. diphya and several Ammonites by which this 

 species is ordinarily accompanied. The next laj^er is rather thick, 

 and consists of a breccia made up in some places of Ammonites, Tere- 

 hratidce, etc., in such excellent preservation and so different to what 

 is found in all other neighbouring layers, that it is impossible to 

 admit the likelihood of a mixture of fossils. I published in the fifth 

 number of 'Verhandlungen der Geologischen Eeichsanstalt,' Vienna, 

 1869, a list of the fossils which are found in the breccia, from which 

 it is apparent that by the side of a great number of forms peculiar to 

 the stage is found one Neocomian, and two or three Jurassic species ; 

 two forms of a Ci'etaceous type, eleven species of a Jurassic type ; 

 eight forms are common to the breccia and to the Stramberg lime- 

 stone, which immediately overlies it at Kiowin Hungary, and on the 

 frontiers of Poland. 



" The fauna of Stramberg is now so well known that it is suffi-
