THE GEOLOGICAL AND FAUNAL RELATIONS 



OF EUROPE AND AMERICA DURING THE 



TERTIARY PERIOD AND THE THEORY ■ 



OF THE SUCCESSIVE INVASIONS OF 



AN AFRICAN FAUNA* 



Several years ago the discovery of some 

 new types of Rhinoceroses in this country 

 directed my attention afresh to the study of 

 the Tertiary fauna of Europe as parallel 

 with that of America. In the succession 

 of European and American types it ap- 

 peared that there were most interesting 

 similarities between rhinoceroses as widely 

 separated as the present regions of Colo- 

 rado and Southern France, but upon at- 

 tempting more than a general comparison 

 I was confronted by a lack of definite time 

 scale between the levels in which these ani- 

 mals occur. The available correlations by 

 Cope, Filhol, Scott, Zittel and others proved 

 too indefinite at certain points. This diffi- 

 culty became so obstructive that a more ex- 

 act correlation of European and American 

 horizons appeared to be an essential basis 

 not only for the phylogeny of the Rhinoc- 

 eroses but for that of other types of mam- 

 mals of Europe and Korth America. 



STRATIGRAPHICAL CORRELATION. 



In an address before the Academy, last 

 year the various steps which have been 

 taken to secure such correlation were de- 

 scribed. The work proves to be a very diffi-
