GEOLOGICAL MEMOIRS. 



been driven, on whose sides the same black limestone is seen, with 

 the red shales reposing on it, but containing few fossils. Thus the 

 Gosau beds lie immediately on the shales which are of the age of the 

 " bunter sandstein," and on the black limestone which is still older. 

 Farther on in the direction of the village of Griinbach, conglome- 

 rate is first found, and soon after the Gosau marls with Inocerami, 

 which continue all the way to Griinbach. The relation of the con- 

 glomerate to the other beds unfortunately could not be ascertained. 



About a mile north of Griinbach, some very abrupt and pointed 

 hills rise, of a remarkably bright yellow colour. These consist of a 

 calcareous sandstone, in all respects similar to that of the Gahnsbauer, 

 only somewhat brighter coloured. It is loaded with innumerable 

 Orbitulites, which at first sight one is disposed to take for Nummulites. 

 Fragments of Inocerami, of large Ostrcece or Gryphcece (possibly 

 Gryphcea vesiculosa), of Hippurites, with a cast of Lyriodon aliforme, 

 were found in it, together with pebbles of the grey Alpine limestone. 

 In these abrupt hills also, although well-exposed to a great height, 

 scarce any stratification can be detected. In one solitary spot, an 

 east and west strike with a northern dip seems to be made out, which 

 would agree with the general strike of the Gosau marls near Griinbach. 

 If so, from this position of the Orbitulite sandstones, which occupy 

 the highest positions and are surrounded by the Gosau marls, the 

 conclusion is, that the sandstones are the newer. Still further north, 

 on the declivity of the ' Vorderwand,' lie thick beds containing Hip- 

 purites, mostly belonging to the species H. costulatus, Goldf. Splendid 

 specimens, with both valves well-preserved, are met with, and along 

 with them Caprina paradooca, Math. (C. Partschii, Hau.), Tornatella 

 Lamarckii, Goldf., and a large undescribed Astrcea. 



South of Griinbach, on the left of the road opposite Rosenthal, 

 the doubtful conglomerate is again met with ; and then, at the place 

 last mentioned, the red shales with Myacites Fassaensis, which con- 

 tinue all the way to Schrattenbach. Here the Alpine limestone 

 comes up, and composes the hill on which Schrattenstein stands. 



The same Alpine limestone continues along the road from Stinen- 

 stein to Flatz on the Gesingberg. In the ravine which leads down 

 from the heights opposite Flatz, a considerable thickness of the shales 

 of the "bunter sandstein" formation occurs. 



Immediately north of Lorenzen, a group of low flattened limestone 

 hills rise, which are separated from the mass of the Kettenloizberg 

 by an intervening valley, and are remarkable even at a distance for 

 their red colour. They consist of a red, sometimes arenaceous lime- 

 stone, and contain, especially on their south-western flank, vast num- 

 bers of plicated Terebratulce, which have not yet been identified. 

 Their general appearance reminds one of the T. concinna of the Jura 

 formation. Few other fossils occur with them, but we may mention 

 a well-preserved valve of a smooth Pecten. On the top of this for- 

 mation lies an extensive plateau of rock, from which the Terebratulce 

 have entirely disappeared ; on the weathered surface, however, vast 

 numbers of organic forms are seen, though seldom distinct enough to 

 allow of determination. Small corals are the most abundant, and on
