Bovidie, were the furcation of the horns and the absence of the " false hoofs," as the 

 stunted terminations of the rudiniental second and fifth digits of each foot ai"e 

 termed, in which latter respect it resembled the Giraftes {Camehpardalis). These 

 three important modifications of structure, when taken together, induced the author 

 to believe that it would be necessaiy to raise the genus Antilocapra to the rank of 

 a family in the series of Ruminanti'a, which he proposed to arrange somewhat as 

 given in the subjoined Table.

In conclusion the author called attention to the geographical distribution of the 

 Ruminants, as shown in the subjoined Table, in which the geographical divisions 

 employed were the same as those used by the author in his paper on the distribu- 

 tion of Birds*, but which he believed to be equally applicable to the class of 

 Mammals.
