steep declivities made it impossible for me to lay down the eastern 

 and western termination of these strata as distinctly as I could have 

 wished to do. 



C. Bed Marble of Graswang and Ettal. — Very well developed 

 strata of this marble, generally of red, sometimes of white or yellow- 

 ish colours, are found in the valley of Graswang and at Ettal, a 

 little north from the mountains. Though the structure of the moun- 

 tains and the position of the strata are here very irregular, as I have 

 endeavoured more fully to describe in my large memoir, it is quite 

 evident, by comparative observations in different localities, that these 

 marbles are generally covered by the white upper A'pine limestone, 

 which dips generally to the north, and contains the same small coral- 

 remains which are so very characteristic of it on the Zugspitze and 

 in other localities. The marbles are clearly underlied by grey and 

 blue marls and limestones, containing in different places Cardium aus- 

 triacum, Gervillia injiata, Nucida complanata, and other fossils cha- 

 racteristic of what we have termed "inferior Lias or Gervillia-strata." 



The marbles lying thus between the upper Alpenkalk and the 

 inferior Lias contain very often numerous specimens of Terebratidce. 

 M. Suess at Vienna, who has recently very thoroughly examined the 

 Brachiopoda of the Trias and Lias formations of the Eastern Alps, 

 recognised among the specimens I had collected Rynchonella Hor- 

 nesi, Suess, and Rhynchonella variabilis, Schlth. 



The Hierlatz-strata of the Austrian Alps, which are characterized 

 by the same fossils, probably form, according to the recent investiga- 

 tions of MM. Hauer and Suess, a part of the Upper Lias (=Adneth 

 strata), though with a very peculiar /act'e*. 



V. Upper Alpine Limestone. 



This formation consists, in the mountain ranges under consideration, 

 of a light-coloured, white, or yellowish limestone, which appears in 

 great masses on the Zugspitze, on the Alpspitze, and on the Wetter- 

 stein, and forms high and steep escarpments. 



These strata here evidently cover all the Jurassic deposits ; but as 

 yet the investigation of the fossils which they contain is not far 

 enough advanced for determining with perfect accuracy the geological 

 age of this Upper Alpenkalk. In different places, for instance on 

 the summit of the Zugspitze, in the Hollenthalkahr, on the Wetter- 

 stein, there occur in this limestone numerous coral-remains. Prof. 

 Schafhaiitl has described and figured some of these corals under the 

 name oi Nullipara annidata"^ . 



I have also been able to collect in the Hollenthal, as well as in the 

 upper Bainthal, not far from the end of the Plattacher Glacier, 

 several specimens of Nei'incsa. According to Von Hauer's comparison 

 of these specimens, they seem to be quite identical with the Neinncea 

 found on the Plassen near Hallstadt. 



"The limestone of the Plassen," he writes, "is almost certainly 

 identical with the fossiliferous strata of Stramberg in Moravia, and
