A NEW FOSSIL RUMINANT GENUS. 



and condyles must entail a corresponding developement in the vertebrae, 

 and modify the form of the neck and anterior extremities. 



The sphenoidal bone, and all the parts along the base of the skull from 

 the occipital foramen to the palate are either removed or so concealed by 

 stone as to give no characters for description. 



The part of the brow from which the nasal bones commence is not 

 distinguishable. The suture connecting them with the frontal is com- 

 pletely obliterated : and it is not seen whether they run up into a sinus 

 in that bone, or how they join on with it. Between the horns there is a 

 rise in the brow, which sinks again a little forward. A short way in 

 advance of a line connecting the anterior angles of the orbits, there is 

 another rise in the brow. From this point, which may be considered their 

 base, the nasal bones commence ascending from the plane of the brow, 

 at a considerable angle. They are broad and well arched at their base, 

 and proceed forward with a convex outline, getting rapidly narrower, to 

 terminate in a point curved downwards, which overhangs the external 

 nostrils. For a considerable part of their length they are joined to the 

 maxillaries : but forwards from the point where they commence narrow- 

 ing, their lower edge is free and separated from the maxillaries by a wide 

 sinus : so that viewed in lateral profile their form very much resembles 

 the upper mandible of a hawk, detached from the lower. Unluckily in 

 the fossil, the anterior margins of the maxillaries are mutilated, so that 

 the exact length of the nasal bone that was free from connection with them 

 cannot be determined. As the fossil stands, about four inches of the lower 

 edge of the nasals, measured along the curve, are free. The same mutila- 

 tion prevents its being seen how near the incisives approached the nasals, 

 with which they do not appear to have been joined. This point is one of 

 great importance, from the structure it implies in the soft parts about the. 

 nose. The height and form of the nasal bones, are the most remarkable 

 feature in the head : viewed from above they are seen to taper rapidly from
