It will be observed that 13 out of the 24 species are common to the North- African and Sinaitic Cretaceous rocks, and that 8 other species are well-known European forms.
The commonest fossils in the collection are Ostrea Auressensis, Exogyra plicata, Plicatula Fourneli, Periaster oblongus, Hemiaster Cenomanensis, and Pseudodiadema variolare. The first of these is evidently one of a great series of varieties having a clear reference to Ostrea columba.
4. On the Existence during the Quaternary Period of a Glacier of the Second Order occupying the " Cirque " of the Valley of Palheres, in the Western part of the Granitic " Massif " of the Lozere. By M. Charles Martins, For. Corr. G.S., Director of the Botanic Garden, Montpellier.
[Abstract*.]
M. Martins refers to the general absence of indications of ancient glacial action in the mountains of central and southern France, and to those circumstances of structure and mineral constitution by which, in some cases, this absence may be accounted for. He describes those features in the conformation of the valley of Palheres, in the Lozere, the representation of which, in the Government Map of France, led him to the conclusion that in this place traces of glacial action might probably be met with. In the gorge in which the village of Palheres is situated, enormous granitic blocks occur ; but these are always either in the torrent, or so near it, that the evidence furnished by them is very doubtful. Above Palheres is a vast " cirque," in which the hamlet of Costeilade is situated ; and here the ground is sprinkled over with erratic blocks, ascending to a considerable height on the slopes of the mountains. The right lateral moraine terminates in a rectilineal crest formed of disintegrated material, but resting on a boss of mica-schist separated from the right
