136 Elliot New Mammals. 



mens, twelve in number, were stated to have been killed out of the same 

 herd), has a small quantity of white on the face. The color of the legs is 

 different from that of both the other named forms, being grayish white 

 on fore legs, but blackish or black and gray on the hind legs. The curve 

 of the horns is between that of 0. moschatm and 0. m. wardi, projecting 

 outward more than in the first, but much less, and closer to the head than 

 in the latter. The skulls exhibit the same intermediate characteristics. 

 Those of moschaltts and wardi in their general characters are nearer to each 

 other than either of them is to that of the present race, which in certain 

 points agrees with both. The nasal bones of moschatus are long and much 

 more slender than those of ward!, while those of the present race are short 

 and broad for their length, but more nearly resemble those of moschatus. 

 The shape of the lacrymal in the new subspecies at once attracts attention, 

 and is quite different from that exhibited by its allies. Forming a portion 

 of the wall of the bony orbit, it is much smaller and less wide than in 

 either of the other forms. In moschatus it is a long bone, widening grad 

 ually from the posterior end to the anterior, the posterior half slanting 

 backward, and at a greatly lessened angle to the anterior portion. The 

 lacrymal bone of wardi is compressed in the middle, the posterior portion 

 standing at a right angle to the anterior, and widening broadly at its forward 

 termination. The lacrymal of the present subspecies, in comparison to those 

 of its relatives is a small bone, in shape nearer that of moschatus than of 

 wardi and, as in the former, not compressed in the middle to any extent, with 

 the posterior end sloping backward even more than in that of moschatus. It 

 resembles therefore the lacrymal of moschatus more than it does that of wardi, 

 but is conspicuously different in its smaller size. The horn cores slant away 

 from the skull more than do those of moschatus, but much less than those of 

 wardi. A ridge runs along the malar beneath the orbit and turning down 

 ward in front of the orbit extends onto the maxilla continuing onwards in 

 moschatus to above the third premolar, in wardi, and the present subspecies 

 to above the fourth premolar. In wardi this ridge is exceedingly sharp, 

 especially in front of the orbit, in moschatus much less so, and in 0. m. 

 niphcecus it is rounded on top along its entire length. On the under surface 

 of the skulls the paroccipital processes attract the eye by their very different 

 size and shape, those of moschatus and wardi, being broad, heavy, and curv 

 ing inward at the tip, while those of the new race are slender, erect, and 

 graduating to the narrow tips, thus presenting an altogether different ap 

 pearance. The bullse of wardi are arcuate in shape, the posterior portion 

 turning outward away from the line of the anterior portion, and are of 

 large size, and but slightly curved on the superior outline. Those of the 

 new form are next in size though not so large as those of wardi, only of a 

 slightly arcuate shape, and greatly curved on the superior outline which 

 is sharp. The bullse of moschatus are the smallest of the three. The 

 postglenoid foramen is widely open in moschatus, much less so in niphcc.cus 

 and greatly contracted in wardi; and the glenoid processes of the three 

 forms are of quite different shapes, being very broad with rounded tips in 

 moschatus, much smaller but of similar form in wardi, and high and narrow 

 in the new subspecies. The basioccipital of 0. m. niphcecus narrows rapidly
