more obtuse and very much less inclined, so as apparently to indicate a longer 

 snout in the extinct animal. The anterior or gingeval border is thick and rough 

 as in other ruminants. 



The small portion of the maxillary bone presents the remains of an alveolus, 

 separated from the tooth of the intermaxillary by an interval, with a curved, 

 acute margin, an inch and three-quarters long. The great distance of this 

 alveolus from the tooth in advance, when compared with the condition of things 

 in the Camel and Lama, arises from the great degree of extension backward and 

 near the palate of the fang of the first functional canine. 



The maxillo-intermaxillary suture, at the side of the fossil, descends, as usual, 

 parallel with the nasal border of the intermaxillary bone, and, after reaching 

 the palatal surface is directed in a curved line forward and inward, reaching as 

 far as the posterior third of the position of the first tooth. 



From this description it is evident the fossil indicates a distinct species of the 

 camel tribe, and as it appears generically distant from the Camel and Lama, the 

 name of Camelops Kansanus would not be inappropriate for it.
