shown in many other localities in the Alps. The Liassic rocks seem
to lie beneath the more ancient limestones and dolomites of the
Traunstein; then in descending order come the Upper Cretaceous
deposits; next follow the Eocene Nummulitic green sandstones, and
lastly the Flysch of the Grunberg, which is nnconformably overlain
by the Glacial drift. The whole of the Vienna sandstone of this
locality is evidently newer than the Eocene Nummulitic green sandstones,
and consequently corresponds to the Flysch of the Swiss
geologists.

On a Palm from the Brown-coal of Eibiswald, in Styria. By D. Stur.
[Proceed. Imp. Geol. Instit. Vienna, July 31, 1868.]
This fossil is the central portion of a large leaf. The rhachis, which is flattened by compression, bears fifteen pinnae, but shows no trace of spines; its length is 14 inches, its breadth 1/3 inch. Three other pinnae lie on the same block in such a position as to place their former connexion with the rhachis beyond doubt. The pinnae on the left side are preserved to a length of from 3 to 4 inches, those on the right side to a length of from 10 to 15 inches; but in all cases the apices are wanting. The distance from pinna to pinna is from 1-1/2 inch to 2 inches; the upper ones are alternate, and the lowest pair nearly opposite. They are linear-lanceolate in shape, the lowest pinna measuring 2 inches in its widest part. The chief nerve is prominent, with three secondary nerves on each side, of which the central one is somewhat stronger than the other and more delicate intermediate nerves. The margin of the pinna is fringed with little spines of about 1/6 inch in length. The whole bears a striking resemblance to the Silhetan species Calamus erectus, Roxb., and may be provisionally placed in the genus Calamus, L., under the name Calamus Mellingi, n. sp., in honour of its discoverer, Mr. Melling, the Superintendent of the Eibiswald coal-mines.

On the Older Brown-coal Flora of the Wetterau (N. W. Germany). By Prof. C. von Ettingshausen.
[Proceed. Imp. Acad. Vienna, April 30, 1868.]
There are six different localities of this flora, which contains 229 species (104 being peculiar), and represents 60 natural orders and 123 genera. The greater number of Miocene forms is met with at Munzenberg, where the Australian types prevail over the Cupressineoe, Ulmaceoe, and Juglandeoe. The tropical forms of the Aquitanian period are represented by the genera Lygodium, Musophyllum, Araliophyllum, and Coesalpina.
At Salzhausen these tropical forms are mixed with a greater proportion of species characteristic of the warm temperate zone, and with some few forms of the (Eningen and Lausanne deposits. [Count M.]
