which are now in existence, in the same country in which these fossils are 

 found. 



M. Faujas, on comparing the different large fossil heads of the ox kind, 

 in the Museum of Natural History, was surprised to find that they dif- 

 fered, not only in their size and form, hut in other characters also, from 

 the urus, or aurochs, of Lithuania. By the examinations which he 

 made, he also became convinced that these fossil horns were of two 

 distinct species. 



The core or bones of the horns of the first species are placed in a hori- 

 zontal position, and at rather more than fifteen inches from their base are 

 fractured; but the size and form of the remaining part show, that, if there 

 had been any curve, it must have been at the extremity. Although the 

 animal must have been young, the bones of the horns, at their base, were 

 more than twelve inches' and a half in circumference ; and the distance 

 from one orbit to the other, more than thirteen inches. The distance 

 from the upper extremity of the forehead to the edge of the occipital 

 foramen is little more than four inches and a half; and on the forehead, 

 between the commencement of the two horns, is a slight protuberance of 

 an oval form. These two last circumstances M. Faujas considers as par- 

 ticularly distinguishing this from the other species. 



In the second species the forehead, which is quite flat, is to be consi- 

 dered, at its upper extremity, rather as forming a line, with a little con- 

 vexity, towards its centre, than as having a protuberance. The horns 

 form a kind of crescent, the inclination of which is downwards. The dis- 

 tance of one horn from the other, taken at their extremities, is two feet 

 six inches and a half; the circumference of the core of the horn, at its 

 base, thirteen inches; and from the upper edge of the forehead to the 

 edge of the occipital foramen, but four inches. 



These horns he considers as having been brought from India by the 

 same revolution which has removed those remains of elephants and rhi- 

 noceroses which are dug up in the North of Europe, in France, Italy, and 

 England.
