The rich Tongrian (Stanipian) fauna is, according to authors, repre- 

 sented in the Sables de Fontainebleau, Pay en Velay, Ronzon, Hempstead, 

 and Cadibona in Italy. We find here Didelphys in abundance, Hyanodon, 

 Amphicyon, Canis, Palceotherium, Paloplotheriuni, Oialicotherium, and Ace- 

 ratherium. Of Artiodadyla, the Suillines are Anthracotherium and Elothe- 

 rium; the Selenodonts, Hyopotamus and Gelocus. This list is the nearest 

 known counterpart of that of the fauna of the White River epoch of North 

 America. To reproduce the latter we must omit from the above catalogue 

 the genera of Palccotheriidoe, and replace them by the allied Clialicotheroid 

 Menodus and Symhorodon, subtract Anthracotherium, and add the great body 

 of the Orcodontida: Then there are included in the White River fauna the 

 higher Selenodont Artiodactyles of the Poehrotheriidw and Hypertragulida^, 

 the corresponding types of which belong to the fauna of St Gerand le Puy 

 in France, or the Aquitanian epoch, which directly succeeded the Stam- 

 pian. In Europe, we have here Dremotherium, Amphitragnlus, Lophiomeryx,
