It has been shown by Boyd-Dawkins 3 that the so-called Bos pri- 

 migenius is in all probability the ancestor of the larger existing cattle 

 of Western Europe ; " the wild cattle of Chillingham Park, Northum- 

 berland, being probably the last surviving representative of the 

 gigantic Urus of the Pleistocene period, reduced in size, and modi- 

 fied in every respect by their small range and their contact with 

 man." The same authority 4 likewise comes to the conclusion that 

 Bos longifrons, Owen, is an ancestral form of the small existing 

 Scotch and Welsh cattle.

The writer has found it totally impossible to distinguish the de- 

 tached jaws, teeth, and skeletal bones of this form from those of 

 the contemporaneous Bison ; the very large series in the Museum 

 showing such an amount of variation in absolute size and relative 

 proportion as apparently to forbid any such division. Under these cir- 

 cumstances nearly all the specimens are provisionally referred to 

 the present form, as being the commoner of the two.
