angles of the skull and sending off a short branch. The bony cores are 

 hollow and were persistent, the neck short and strong, as demonstrated 

 by the vertebra, No. 1252, and the animal is evidently to be referred to 

 the Antelope family ; in which alone a Ruminant with four horns is still 

 exemplified in the existing Indian species, called Antilope guadricornis. 



Family Bovida. 



Subgenus Urus, Aurochs. 



1254. The calvarium and bony cores of the horns of the great extinct Aurochs, 



Urus prisons, Owen. This fine specimen was dug out of a stratum of 

 dark-coloured clay, below layers of brick-earth and gravel, thirty feet 

 from the surface, at Woolwich ; it presents the broad convex forehead, 

 the advanced position of the horns, which rise three inches anterior to 

 the upper occipital ridge, and the obtuse-angled junction of the occipital 

 with the coronal or frontal surface of the skull, all which characters di- 

 stinguish that part of the skeleton of the Aurochs. The bony cores of 

 the horns extend outwards, with a slight curvature upwards : from the 

 mid-line between their bases to the extremity of one core, in a straight 

 line, measures two feet five inches. Hunterian. 



1255. Fragments of the cranium and the bony cores of both horns of the extinct 



Aurochs (Urus priscus), with the same essential characters as the pre- 

 ceding in regard to the position of the horn- cores ; they are relatively 

 thicker, shorter and more curved in this specimen. From the mid-line 

 between their bases to the extremity of one core, in a straight line, mea- 

 sures two feet two inches. 



From the brick-earth (Pleistocene) at Ilford, Essex.

1256. Fragments of a cranium, with great part of both horn-cores, of the extinct 

 Aurochs (Urus priscus). It resembes, but is rather smaller than the pre- 

 ceding.
