﻿FR. VON HAUER ON SOME OUTLIERS OF THE ALPS. 87 



Gahnsbauer, with the same mineral character and containing frag- 

 ments of Inoceramus. 



A road leads from Priiglitz by a pass called the Hals, through 

 Breitensol near Rohrbach to Buchberg. This road proved most in- 

 teresting, not only from the picturesque beauty of the scene, but from 

 the important geological discoveries which were made along it. Brei- 

 tensol lies in a pleasing valley of no great extent, formed of beds of the 

 Gosau formation and surrounded by high hills. Immediately to the 

 south, at a distance of scarce a hundred paces, a marly sandstone is 

 seen in several quarries containing abundance of Orbitulites, as on 

 the declivity of the Gahnsberg. With them occur — 



Pectunculus, n. sp. This species is the same which occurs fre- 

 quently in the marls of the Gosau formation of Muthmansdorff, in 

 the district called the New World [neue Welt] , to the westward of 

 Neustadt. 



Turrit ella, sp. ? — with other Gosau fossils. 



North of Breitensol the valley widens out, and on its eastern side, 

 opposite to the Schacherberg, very interesting fossils are found in 

 great quantities in the loose stones which have been collected for 

 building purposes. Among them are large and beautiful specimens 

 of a Gryphcea, probably identical with G. vesicularis. 



Pecten, n. sp., very like the P. latissimus of the Leitha limestone, 

 but distinguishable by sharper and more numerous tubercles on 

 the ribs. The same species is found in the Gosau formation N. of 

 Griinbach. 



Pectunculus, n. sp., same as that before noticed. 



Inoceramus, large and well-preserved ; agreeing with those of the 

 Gosau formation. 



Orbitulites have not been found here, and their absence seems to 

 be connected with the change in the mineralogical condition of the 

 rock, which here is not sandy, but resembles the common Gosau 

 marls. 



Farther to the north of Breitensol, a ravine, which is partly artifi- 

 cial, leads into the valley of the stream which flows by Rohrbach. 

 The rocks, which at a distance closely resemble the Alpine limestone, 

 and form equally abrupt precipices, prove under the hammer to be a 

 coarse conglomerate. 



At Buchberg a projecting headland of black limestone with veins 

 of white calcareous spar appears. This belongs to the older Alpine 

 limestone, as may be ascertained by examining the narrow ravine 

 which leads from Pfennigbach to Ratzenberg. Regular beds of this 

 limestone are here overlaid by an equal thickness of red and green 

 shales, which contain the Myacites fassaensis, and other bivalves of 

 the " red shale of Werfen." The whole system of these shales is 

 most distinctly seen in the bed of the stream which flows through 

 Pfennigbach ; its strike is E. and W. with a northern dip. Farther 

 on in the same ravine great masses of the black limestone are seen, 

 extending to the plateau of Ratzenberg, which is composed of the 

 coal-bearing beds of the Gosau formation. North of Ratzenberg this 

 plateau sinks, and farther down on the road to Vorau a gallery has
