first column are those assigned in the catalogue of the department 

 of vertebrate paleontology in the United States National Museum. 



Table of measurements of teeth of Camelops huerfanensis. 



On comparison of the structure of the teeth of Cragin's type 

 specimen and that from Denver, few differences are observed, and 

 these are probably not important. The median style of the Denver 

 teeth is more undercut than in the type specimen, and the spaces 

 between the styles are somewhat more elevated. In the figure 

 showing the grinding surfaces the latter appear much broader in 

 the type than in the Denver specimen, but this is because the teeth 

 of the type are worn down farther toward the base. 



There are some lower teeth to be described. 



Table of measurements of lower teeth of C. huerfanensis. 



Inasmuch as the lower teeth of the type of C. huerfanensis are to a 

 considerable extent hidden in the bone, some of their dimensions can 

 not be secured. The right lower second molar from Denver is a 

 thinner tooth than the corresponding one of the type. It is possible, 

 of course, that this Denver tooth did not belong to the same species 

 as the other teeth. Leidy 3 referred a lower second molar to his 

 Megalomeryx niobrarensis. In its less wedgelike form it is different 

 from the corresponding molar from Denver, and it is larger; other- 

 wise the teeth are not greatly different. The lower left hindermost 

 molar is represented by figure 7 of plate 116. The Denver teeth appear 

 not to be much different from camel teeth found at Minidoka, Idaho, 

 and described by the writer in 1913. 4 In the United States National 

 Museum there is a lower left hindermost molar (Cat. No. 8252) of a 

 camel which w r as sent from Wakonda, Turner County, South Dakota.
