Description. — This fossil Wild Ox, of whose skull the mu- 

 seum here possesses both an old and a young specimen, forms a 

 very different kind from any I have yet seen. It has however 

 some remote resemblance to the Bison, through its convex 

 forehead and its horn-pedicles. The old specimen, probably a 

 bull, whose cranium is here delineated in face and profile, has 

 the forehead between the horns convex ; below, where it is the 

 smallest, flat-rounded; between the eyes broad, hollowed. The 

 ridge of the occiput thick, rounded, in the centre rising and 

 strongly curved. The nasal bones seem to reach up to the line 

 drawn over the sockets of the eyes. The horn-cores, which rest 

 on longer pedicles than among any known species of Ox, are di- 

 rected outwards and backwards, also somewhat curved down- 

 wards in the same direction as the front of the forehead, above 

 which they do not rise. They have the back and front somewhat 

 flat-round, so that a transverse section would form more or less an 

 oval. The outer edge of the zygomatic process of the temporal 

 bone forms above the socket of the under-jaw nearly a right angle.
