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

 sented in the Sables de Fontainebleau, Puy en Velay, Eonzon, Hempstead, 

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

 Amphicyon, Cynodon, FalcBotherium, Faloplotherium, Chalicotherium, and 

 Aceratherium. Of Artiodactyla, the Suillines are AnthracotJierium and 

 MotJierium ; the Selenodonts, Hyopotamus and Gelocus. This list is the 

 nearest known counterpart of that of the fauna of the White Eiver 

 epoch of JSTorth America. To reproduce the latter, we must omit from 

 the above catalogue the genera of Falwotheriidce, and replace them by 

 the allied Chalicotheroid Menodus and Symhorodon, subtract Anthra- 

 cothermm, and add the great body of the Oreodontidce. Then there are 

 included in the White Eiver fauna the higher Selenodont Artiodactyles 

 of the FoebrotJieriidcB and SypertraguUdce, the corresponding types of 

 which belong to the fauna of St. Gerand le Puy in France, or the 

 Aquitanian epoch, which directly succeeded the Stampian. In Eu- 

 rope we have here Dremotlierium, Ampliitragulus, LopMomeryx^ Dor- 

 catherium ; in America, Leptomeryx, Sypertragulus, Hypisodus, and Foe- 

 brotherium. It is curious that while Leptomeryx is also European,* it 

 has not yet been found above the Phosphorites. Among Suillines, the 

 FalceoeJicerusi of the Oregon White Eiver beds has also not been found 



* I think M. Filhol's Prodremotherium is identical with Leptomeryx. 

 t Thinohyus Marsli appears to be the same.
