A NEW ANTELOPE FROM THE PLEISTO- 

 CENE OF RANCHO LA BREA 



BY

INTRODUCTION 



Among the specimens in the collection of the University of 

 California from the Pleistocene of Rancho La Brea are a number 

 of fragments representing a very small antelope-like form which 

 has not been recognized heretofore in the Pleistocene of the Cali- 

 fornian region. The characters of the dentition indicate that this 

 species is probably referable to the genus Capromeryx described 

 by W. D. Matthew from the Pleistocene of Hay Springs, 

 Nebraska . 



The material available comprises three imperfect lower jaws, 

 a number of metapodials. mostly posterior, two phalanges, and 

 an astragalus. These were all found close together in the fossil 

 beds, and presumably pertain to the same species. It is highly 

 probable that certain of the elements mentioned belong to one 

 individual, but of this it is impossible to be certain. 



Few antelope-like artiodactyls have been obtained in North 

 America. The presence in the Miocene and early Pliocene of 

 the genus Merycodus, so peculiarly combining the characters of 

 the antelopine and cervine groups in that it possesses hypsodont 

 teeth but deer-like horns, naturally suggests that more typical 

 antelopes might be expected in the later Pliocene and Pleistocene. 



The Recent prong-horn, Antilocapra americana, has been
