 [16.] Ei7i geologisches Profit aus der BucJit von BercMoldsdorf. 

 (pp. 117-132.) By Felix Karrer. 



The sinking of six wells in a continuous line lias shown clay 

 alternating with "" Leitha-conglomerate." Samples from both beds 

 were examined for organic remains in each sinking. Foraminifera 

 constitute the bulk of the lists and their degree of abundance in 

 each case is very carefully set down, and finally embodied in a 

 table. 



[17.] Bas Alter des Eohrhacher Conglomerates, (pp. 132-136.) 

 By Felix Karrer. 



Excavations for the foundation of a bridge have shown that this 

 conglomerate rests on a cla}^ in which the author found the following 

 Foraminifera : Nonionina granosa, Folystomella oitusa, and Hauerina. 

 These prove that the clay belongs to the " Sarmatic " horizon ; hence 

 the conglomerate is newer than the Leitha-conglomerate, and may 

 possibly belong to the Congeria-beds. E. B. T. 



2. — Beitrdge zur topischen Geologie der Alpen der BhaetiJcon [Vorarl- 

 herg). (pp. 137-174, with a geological map and plate of sections.) 

 By Dr. Ed. von Mojsisovics. 



In referring to the break produced in the Trias deposits by the 

 Ehine valley, the author argues against the notion of their having 

 once been present on both sides of the valley, and their absence ou 

 the west side being due to dislocations and denudation. He infers 

 that this line marks rather the original boundary ; and points out 

 the transgressive character of the Trias deposits on the east side, and 

 again that on the west side the Verrucano (Dyas) is overlain by 

 Lias; moreover, in the Vorarlberg, the strike of the Trias beds, 

 which in the eastern district has been mostly east and west, verges 

 round to an almost north and south direction. This paper, besides 

 new facts, contains many suggestions on theories of Alpine elevation.

3. — Der Graptolithen-ScMefer am Osternig-Berge in Kdrnten. (pp. 

 175-248.) By Dr. Guido Stache. 



Controverts views of Prof. Suess, according to which certain mica- 

 schists and granites which occur in them {e.g. Cima d'Asta granite) 

 are all of Carboniferous age ; these schists being by him grouped as 

 Casanna-schists. and placed above the Carboniferous beds of the 

 Stangalp. Stigmatizes these assertions as too speculative, and shows 

 that the Casanna-schists instead of being simply Upper Carbonifer- 

 ous, contain other and much older beds, probably in the Casanna 

 district, and indubitably in the Gailthal. The Graptolites found in 

 schists at Gsternig-Bei'g show beds of the age of the Coniston flags. 

 The Upper Silurian is also represented, as shown by fossils ; and
