This group, adds M. von Buch, differs essentially from the shelly beds spread 
out over Podolia, particularly those of Bielazurska, all of which correspond with 
the Sub-Apennine formations of Brocchi in Italy. 
The determinations and inference of M. von Buch are of high value when coupled 
with the general description of the region by M. Dubois. The latter has assured us, 
that nothing can be more dissimilar in lithological aspect than the tertiary forma- 
tions which lie respectively to the north and south of the great granitic plateau of 
Yolhynia and Podolia ; the northern zone being in general siliceous and talcose 
with clay, the southern eminently calcareous. “ This difference,” adds M. Du- 
bois, “ drawn from lithological characters, is still more striking as based upon the 
fossils. According to my view, it is an ascertained fact, that the tertiary rocks of 
the Ukraine and of the banks of the Dnieper (upper part) are analogous to those of 
the basin of Paris, or what is termed the lower tertiary stage ; whilst that of Gallicia 
(Poland), Podolia, Volhynia, &e. is of the age of the Sub-Apennine regions, or 
of the middle tertiary epoch.” (Letter to Mr. Murchison, 1843.) 
1 The letters L.C. indicate that the species occurs also in the London clay. Many of these shells were 
named by M. von Buch at an earlier period. See Bull, de Soc. Geol. de France, vol.vii. p. 157.
