BOS PRIMIGENIUS. 507 



Fossiles 1 (1823), no authentic example had been recorded 

 of a cranium of either Bison priscus or Bos primigenius 

 in strata containing bones of the Mammoth and Rhino- 

 ceros ; and this statement is repeated in the, posthumous 

 edition of the ' Ossemens Fossiles, 1 8vo, 1835. The skull 

 of the Aurochs in the Darmstadt collection, cited by M. 

 v. Meyer, and the examples of the Bison priscus from 

 newer pliocene freshwater deposits in Kent and Essex, 

 described in the foregoing section, leave no reasonable 

 doubt that a large Aurochs was the associate of the gi- 

 gantic Pachyderms, whose representatives at the present 

 day have the Buffaloes for their companions in the tropical 

 swamps and forests. It is true that species of true Bos 

 are found wild in the warmer parts of Asia ; but no true 

 Aurochs has been discovered within the tropics. That 

 the great Aurochs was associated with a species of Bos 

 of equal size in England during the newer pliocene period, 

 is equally demonstrated by the fossils which form the sub- 

 ject of the present sections.
