Summary. — This Dallas form resembles Camelops 

 huerfanensis in size and general proportions, in so far 

 as comparison may be made, but differs in the details of 

 the occipnt, the presence of diastemata between P and 

 the canines, and in the larger size of the metastyle of M^. 

 These characters, if they are not merely sexual, are 

 at least of subspecific rank. The name dallasi is given 

 therefore to the form based upon the skull as holotype.

No. 1.63, S. M. U., an almost perfect rear cannon-bone, 

 represents a considerably smaller camel than C. liuer- 

 fanensis, but I can not as yet identify it.
