It was after mes miocene epoch that Spain was elevated to its present 
height above the cause seems to have had its maximum en- 
ergy along a line pee by the mountains of Burgos and Soria and 
which extends towards Siguenza and the sources of the Tagus. The 
inclination of the miocene beds to the southwest was thus occasioned, 
a position which probably allowed the lacustrine waters of the period 
to flow out by the valleys along which run the Duero, the Tagus and 
the Guadiana.

tains descriptions and figures of all the fossils yet observed by the au-

limestone, and Onondaga salt-group. The entire ‘number of species is 
344, and the whole number of plates 101. The printing of the vol- 
ume was nearly completed in 1850, and its issue has been prevented 
by delays in the engraving; and on this account, as its author states,
