Bg aes usually unfossiliferous, but where it passes into limestone some-

3rd series of shaly, sandy, and marly rocks, comprising in dif- 
ferent localities the following groups of strata— 
Cardita beds, with numerous fossils. Limestone-Alps of 
North Tyvrol. 
Gorno and Dossena beds. Lombardy Alps. 
Raibl-beds—shales, marls, &c., comprising abundant or- 
ganisms (plants, crustaceans, cephalopods, fishes) ; Southern 
Carinthia. 
2nd series of calcareous and dolomitic rocks, with varying 
local development— 
Potschen Limestone, containing fossils like those of the 
Hallstatt Limestone. 
Hallstatt Limestone—a red and mottled marble which in the 
Salzkammergut lies on the Zlambach beds. Its fossils, 
chiefly cephalopods, some of them of gigantic size, are 
among the most interesting of the Alpine Trias. 
Wetterstein Limestone and Dolomite, in North Tyrol and the 
Bavarian Alps, lying on the Partnach beds. 
Esino Limestone, characterized by its large gasteropods, nume- 
rous lamellibranchs, and cephalopods. 
Schlern Dolomite, a white saccharoid rock, containing chiefly 
foraminifera, 3280 feet thick, forming picturesque groups of 
mountains (Diplopora annulata, Chemnitzia, Natica). 
Ist series of shaly and marly formations— 
Lunz beds, containing seams of coal and abundant terrestrial 
plants, and forming the only known fresh-water group in 
the upper Alpine Trias. 
_ Partnach beds, dark, poorly fossiliferous shales. 
Zlambach beds—marls and hornstone-like limestone, containing 
an abundant fauna with large cephalopods, lamellibranchs, 
and numerous corals. 
St. Cassian beds—calcareous marls lying at St. Cassian, South 
Tyrol, above the Wengen beds, and marked by their extra- 
ordinarily rich fauna (837 ammonites, 3 orthoceratites, 205 
gasteropods, 70 lamellibranchs, 33 brachiopods, 29 echini, 
10 crinoids, 42 corals, and 36 sponges are described). 
Wengen beds—dark shales and tuff-sandstones with Daonella 
(Halobia) Lommeli, Posidonomya Wengensis, and Ammonites 
of the Trachyceras group, resting on the tuffaceous and 
siliceous Buchenstein beds. 
2nd. Virgloria Limestone (Wellenkalk) or Alpine Muschelkalk 
—a series of limestones and dolomites composed of the following 
roups— 
Fi b. Cephalopod Limestone (Reiflinger Kalk), with numerous 
cephalopods (Ammonites (Arcestes) Studert, Ceratites bino- 
dosus). 
a. Brachiopod Limestone (Recoarokalk), distinguished by the 
number of its brachiopods (Retzia trigonella, Spiriferina 
Mentzeli, &c.). 
Ist. Werfen (Groden) Sandstones and Guttenstein Lime- 
stone (Seisser, Campiler Schichten). (Pleuromya fassaensis, 
Posidonomya Clarat, Avicula venetiana, Naticella costata, Turbo 
rectecostatus, Ceratites cassianus, &c.). These beds may be 
paralleled with the Roth or uppermost division of the German 
Bunter. 3 D 
granite, 
y variable formations, attaining sometimes a depth 
of thousands of feet, with associated eruptive rocks (well seen round the Lake of 
in South Tyrol), consisting of monzonite, tourmaline- 
melaphyre, augite-porphyry, syenite-porphyry, and interstratified tufts. 
Upper Trias—a series of exceeding! 
Lugano, and near Botzen, 
Lower Trias—a much thinner 
series than the Upper.
