| Upper group. | Calcareous sands and pebble beds, calcareous grits and oolitic limestone in the low ground of Hungary full of shells, as in the highest beds of the basin of Vienna.
| |
White and blue marl, calcareous grit, white marlstone, and concretionary white limestone: shelly.
| ||
| Middle group. | Coralline limestone and marl, of a yellowish white colour, very thick and shelly (Leithakalk of Vienna.)
| |
| Lower group. | Conglomerate, with micaceo-calcareous sand and millstone conglomerate: thick.
| |
Blue marly shale, sand, &c., full of shells compared to those of London clay and calcaire grossier.
| ||
Shale and sandstone, with coal or lignite, containing bones of anthracotheria, gyrogonites, &c.
| ||
Micaceous sandstones, grits, and conglomerates, made up of the detritus of the primary slaty rocks, on which they rest at high angles of inclination.

The authors consider the lower group to correspond with the calcaire grossier and Palæotherian deposits; the middle to the English crag, and middle subapennines. According to M. Dufrenoy, the former would rather appear to belong to the middle tertiary period. In his latest memoir on the Alps and Carpathians, Sir R. Murchison expresses the conviction that the flanks of the Alps exhibit a true transition from the younger secondary into the older tertiary strata, and that the older supracretaceous rocks occur abundantly, and well characterized, in the South of Europe, extending thence eastward into Asia. The cretaceous beds, containing inoceramus and ananchytes, are conformed in position to the overlying tertiary rocks characterized by nummulites, and in this latter series we still find gryphæa vesicularis.[1]
