Ixvi PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



with the genus Mitra, and we are informed by the notices given out 

 by the officers of the Palseontographical Society, that the forthcoming 

 volume for 1855 will contain the fourth Part of the Eocene Mol- 

 lusca with ten plates. There is, therefore, a reasonable expectation 

 that this work, which has long been anxiously looked for by the 

 students of Tertiary Geology, will now rapidly advance towards com- 

 pletion. 



It is impossible for me even to allude to all the valuable papers 

 on British Geology which have appeared in the numerous metro- 

 politan and provincial journals during the past year, many of which 

 are of great importance and deserving careful study. 



Foreign Geology. 



France. — The volumes of the Bulletin of the Geological Society 

 of France bear ample testimony to the active exertions of our neigh- 

 bours in the cause of geological inquiry. I regret that neither time 

 nor space will permit me to do full justice to the many able memoirs 

 they contain. I must refer you to the volumes themselves for in- 

 formation, merely premising that the structure of the great Alpine 

 formations, and the geology of the principal secondary formations 

 seem chiefly to have attracted the attention of the French geologists. 



Amongst the principal memoirs contained in the Bulletin, T may, 

 however, mention the following : — A Notice on the Age of the lower 

 and middle beds of the Coralline Group (Coral rag) in the depart- 

 ment of the Yonne, by M. G. Cotteau. With a complete list of 

 Fossils found in the Coral rag and Oxford Clay. 



M. Jules Baudouin laid before the Society a geological map of the 

 district of Chatillon sur Seine, laid down between 1840 and 1855 on 

 the topographical survey of the Depot general de la Guerre, accom- 

 panied by full details of the different formations which occur in that 

 locality. 



M. Omboni read a communication on the sedimentary formations 

 of Lombardy, and on the structure of the southern flanks of the Alps, 

 from the Tyrol to the vicinity of the Lago Maggiore. A geological 

 map and section accompany the m.emoir. M. Omboni has proved 

 the existence in this region of several of the secondary formations of 

 Europe, and particularly of the Muschel-kalk of Werner. 



The following formations are described: — 1. Recent deposits; 

 2. Erratic formations ; 3. Tertiary; 4. Cretaceous deposits ; 5. Ju- 

 rassic; 6. St. Casciano groups; 7. Triassic; 8. Permian; 9. Car- 

 boniferous; 10. Crystalline formations. 



The Marquis de Pareto has communicated a notice on the num- 

 mulitic formation at the foot of the Apennines. 



M. Pomel communicated a geological account of the country of 

 the Beni Bou Said, near the frontier of Morocco. 



But I must more particularly allude to an interesting series of 

 papers and discussions respecting the age of the Anthraxiferous 

 formations of the Alps.
