INTRODUCTION 



Since the description of Capromeryx minor Taylor was published 

 in 1911 1 from a number of fragments found in the Raneho La Brea 

 beds, there has been a considerable accumulation of material referable 

 to this species. A study of these specimens brings out a number of 

 interesting points regarding the structure of this animal. Some of 

 these points have a direct bearing on the relationships of Capromeryx. 

 With the material now at hand, a very fair estimate of the characters 

 of the animal may be made. 



As was pointed out by Taylor, Capromeryx is a form of especial 

 interest, since so few antelope-like animals have been obtained in 

 North America, and as yet the relationships of those which have been 

 found are very imperfectly known, so that every addition to our 

 knowledge of any antelope-like form is important. 



The material now at hand includes the majority of the limb and 

 foot bones, lower jaws with complete dentition of both milk and per- 

 manent sets, fragments of the upper jaw, two pieces of skulls, both 

 including the region of the horn-core, and several vertebrae.
