[Geology 



Though it is not possible to make a definite determination of 

 the affinities of the form represented by this specimen, it is 

 probable that it represents a large, antelope-like type similar 

 to Dromomeryx. 



ANTILOCAPRIDAE 

 MERYCODUS, near FURCATUS (Leidy) 

 The genus Merycodus is represented by a number of antlers 



(fig. 66) from Virgin Valley. 

 If The best preserved antler 



from Virgin Valley extends 

 upward to a height of 110 

 mm. above the base without 

 branching. The middle of 

 the burr is 25 mm. above the 

 base. It seems to resemble 

 M. furcatus most nearly, 

 though the several specimens 

 of antlers known average a 

 little smaller than M. fur- 

 catus, and the burr is a little 

 higher.
