limestone of Wildon, may correspond in age to the Paris basin ; 
but the list of fossils which they have given, seems rather to 
favour the supposition, that the deposit is of the Miocene era. 
They enumerate four characteristic Miocene fossils, — Mytilus 
Brardii, Cerithium pictum, C. pupaeforme, and C. plicatum, — 
and if there are some few of the associated shells common to 
the Paris basin, such a coincidence is no more than holds true 
in regard to all the European Miocene formations. 
On the other hand, the third or newest system, which over- 
lies the coralline limestone, contains fossils which do not appear 
to depart so widely from the Miocene type as to authorize us 
to separate them. They appear to agree with the tertiary 
strata of a great part of Hungary and Transylvania, which 
will be seen, by the tables of shells in Appendix I., to be re- 
ferable to the Miocene period. 
Volhynia and Podolia. — We may expect to find many other 
districts in Europe, composed of Miocene strata, and there ap- 
pears already to be sufficient evidence that the marine deposits 
of the platform of Volhynia and Podolia were of this era. 
The fossils of that region, which is bounded by Galicia on the 
west, and the Ukraine on the east, and comprises parts of the 
basins of the Bog and the Dniester, has been investigated by 
Von Buch, Eichwald, and Du Bois, and the latter has given 
excellent plates of more than one hundred fossil shells of the 
country, which M. Deshayes finds to agree decidedly with the 
fossils of the Miocene period *. 
The formation consists of different rocks, sand and sand- 
stone, clay, coarse limestone, and a white oolite, the last of 
which is of great extent. 
Montpellier. — The tertiary strata of Montpellier contain 
many of the Dax and Bordeaux species of shells, so that they 
are probably referrible to the Miocene epoch ; but in the cata- 
logue given by M. Marcel de Serres, many Pliocene species, 
similar to those of the Subapennine beds, are enumerated.
