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

 stinguishable. The suture connecting them with the frontal is completely 

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

 bone, or how they join on with it. Becween 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 nay 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 consi- 

 derable part of their length they are joined to the maxillaries : but for- 

 wards from the point where they commence narrowing, 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 mar- 

 gins of the maxillaries are mutilated, so that the exact length of the nasal 

 bone that was free from connexion with them cannot be determined. As 

 the fossil stands, about four inches of the lower edge of the nasals, mea- 

 sured along the curve, are free. The same mutilation 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 a broad base to a 

 sharp point; and the vertical height of their most convex part above the 

 brow at their base, is 3J inches. 



The form of the maxillaries is strongly marked in two respects : 1st, 

 their shortness compared with their great width and depth : 2nd, in the 

 upward direction of the line of alveoli from the last molar forwards, 

 giving the appearance (with the licence of language intended to convey 

 an idea of resemblance without implying more) as if the face had been 

 pushed upwards to correspond with the rise in the nasals ; or fixed on at 

 an ancle with the base of the cranium. The tendency to shortness of the 

 jaw was observed in the dimensions of the teeth, the molars being com- 

 pressed, and their width exceeding their length to an extent not usual in 

 the Ruminantia. The width apart, between the maxillaries, was noticed 

 before ; the interval, between the outer surfaces of the alveoli, equalling 

 the space in length occupied by the line of molars. The cheek tuberosities 

 are very large and prominent, their diameter at the base being 2 inches, 

 and the width of the jaw over them being 12'2 inches, whereas at the 

 alveoli it is but 9-8 inches. They are situated over the third and fourth 

 molars; and proceeding up from them towards the malar, there is an in- 

 distinct ridge on the bone. The infra-orbitary foramen is of large size, 

 its vertical diameter being 1-2 inch : it is placed over the first molar, as in 

 the ox and deer tribe. The muzzle portion of the bone is broken off at 

 about 2-8 inches from the 1st molar, from the alveolar margin of which, 

 to the surface of the diastema, there is an abrupt sink of 1"7 inch. The 

 muzzle is here contracted to 3-8 inches, and forwards at the truncated 

 part to about 4-1. The palatine arch is convex from rear to front, and 

 concave across. No trace of the palatine foramina remains, nor of the 

 suture with the proper palatine bones. The spheno-palatine apophyses 

 and all back to the foramen magnum * are either removed or concealed in 

 stone. In front, the mutilation of the bone, at the nmzzle, does not allow 

 it to be seen how the incisive bones were connected with the maxillaries: 

 but it appears that they did not reach so high on the maxillaries as the 



* With the exception of a portion of the basilary region, which resembles 

 that of the Ruminants.
