Palseozoie slates. A fine series of fish remains from these beds maybe seen in the Geological Collection of the British Museum. No fewer than fifty-three species of fish have been identified anddescribed, together with two Sea-turtles and two Birds. We subjoina figure of one of the turtles. Fig. 4. Fig. Fig. 4.

The birds (Protornis Bhimeri, Heer, and P. glaronensis, Meyer)were about the size of Larks, and appear to have belonged to thefamily of Finches. The Glaris slate-rock is the oldest of these Swiss Tertiary deposits,and, like the beds of Monte Bolca, is of Middle Eocene age. Aboveit is the Nummulitic formation of Ealligstocke, and the newest, theshales of Mauremont, Soleure, and Obergosgen, containing remainsof no fewer than twenty-five genera of terrestrial Mammalia, togetherwith twelve Eeptilia represented by Chelonige, Ophidia, and Crocodilia. Nearly one-fifth of the area of Switzerland (about 152 squaregeographical miles), comprising the lowland, undulating countrybetween the Jura and the Alps, is covered by masses of marls andsandstones, which have received the general name of Molasse,and include
