3. Septaria clay of Magdeburg, Berlin, Stettin, &c. 



4. Brown-coal of Brandenburg, Silesia, Poland, &c. 



5. Tertiary beds of Gallicia, — the equivalents of the Vienna basin. 

 The recent investigations of the Austrian geologists, encouraged 



by the establishment of the Imperial Geological Institute of Vienna, 

 and the admirable publication of the fossils of the Vienna basin by 

 Homes, have led to the more perfect examination of other beds con- 

 taining an identical fossil fauna in other portions of the Austrian 

 empire, and especially in Hungary and Transylvania. 



In the 5th vol. of the * Journal of the German Geological Society' 

 is an interesting account by Prof. Neugeboren of the fossil remains 

 found at Ober Lapugy in Transylvania, in the valley of the Marosch, 

 not far from the Banatic frontier. Prof. Neugeboren describes this 

 locality as one of unusual interest. A bed of clay upwards of 300 

 feet in thickness, occupying the small extent of 1 000 square toises, 

 about 40,000 square feet, represents the whole of the tertiary de- 

 posits of the Vienna basin. In the formation of these deposits there 

 has been no interruption or break whatever. The whole has been 

 formed in one long period of continued repose ; almost every species 

 from the different groups of the Vienna basin has been found here 

 in the most perfect state of preservation, together with many others 

 not yet found near Vienna, viz. Conus nocturnus. Lam. ; Cyprcea 

 rugosa, Grat. ; Cyprcea Hdrnesi, Neugeb. ; Marginella Deshayesii, 

 Michelotti ; Mitra striato-plicata, Bellardi ; Colmnhella Bujardiniy 

 Homes, &c. Thus we have here a gradual passage from the Mio- 

 cene to the Pliocene formation without any break, the upper beds of 

 the Vienna basin being considered the equivalents of the Subapen- 

 nine formation in Italy. This opinion is confirmed by Prof. Reuss, 

 who, in his examination of the Foraminifera, &c. of Upper Silesia, 

 found many forms identical with those of the Subapennine formation 

 of Castell'arquato, besides others still living in the Adriatic. 



We also learn from the reports of the meeting of the Imperial 

 Geological Institute of Vienna, that Dr. Homes visited Hungary and 

 Transylvania last summer, principally for the purpose of ascertaining 

 how far the tertiary deposits in those countries coincided with those 

 of the Vienna basin. He has reported that the mineralogical and 

 palseontological points of resemblance between these two widely 

 separated regions are so complete, that there can be little doubt, if 

 any, of their perfect identity. The sea, which, during the period of 

 their deposit, occupied the Vienna basin, seems, as Dr. Homes 

 reports, to have been the connecting link between two large con- 

 temporaneous oceans, the one covering the upper Danubian basin, 

 the other the plains of Central Hungary, as in the present day 

 the Sea of Marmora forms the connexion between the Black Sea 

 and the ^gean. The tertiary deposits of Korod and Lapugy in 

 Transylvania, of Remesert in Banat, of Baden, Steinabrunn and 

 Oltnanz in Austria, together with those of Vilshofen in Bavaria, of 

 S. Gallen in Switzerland, and of Montpellier, Bordeaux, andTouraine 

 in France, whose faunas (with the exception of local modifications) 

 have all the same character, may serve to point out the extent of the
