the determination of the true affinities of that genus beyond 

 what was suggested by the type specimen. The characters of 

 the cranium and superior dentition seem to point out the same 

 general position with relation to the other types of canids. 

 This we may consider as evidence that the two specimens really 

 represent the same group. It will be necessary to know some- 

 thing of the limb structure, as also something of the history of 

 the group, before we shall have thoroughly satisfactory evidence 

 concerning its true relationships.
