FAMILY II. ANTILOCAPRID^. 



Closely allied to the Bovidcv, but the horns, which are 

 of the same general type as those of that family, forked and 

 annually deciduous. Lyon,* following Cope, considers that 

 there is no sufficient reason for separating the one existing 

 genus by which this family is represented from the Bovidce. 

 " Its true position," he remarks, " is clearly no more than an 

 aberrant subfamily, Antilocaprince of the Bovidce, . . . the 

 essential, characters of the subfamily being horns deciduous, 

 with a characteristic branch or prong in front, and absence 

 of annual rings of growth at base of horn." 



On the other hand, Matthew, f after first provisionally 

 referring it to a separate family Merycodontidce apparently 

 considers that the American Tertiary genus Merycodus, which 

 has antlers instead of horns, should be included in the 

 Antilocapridce. Certain other North American Tertiary 

 (Pleistocene) ruminants, described as Ilingoceros and Spheno- 

 phalos, and at first regarded as referable to the Tragelaphince, 

 have been tentatively transferred to the present family,:} the 

 definition of which will have to be materially modified if 

 any or all of the above are rightly included. 



The distribution is restricted to North America.
