Merriam: Mammalian Remains from the Tejon Hills 



127 



from the Tejon Hills is too fragmentary, and the characters of the 

 western Pliocene species are as yet too imperfectly known to permit a 

 satisfactory comparison. 



CAMELID, indet. 



A fragment of the distal end of a large metapodial (no. 22377) 

 from locality 2751 represents a camelid possibly of the Pliauchenia 

 type. Other very fragmentary material also indicates the presence of 

 large camels, but the material available is not sufficient to furnish the 

 basis for even a generic determination. 



MEBYCODUS, near NECATUS Leidy 

 Fragmentary material obtained in the Tejon Hills region by R. W. 

 Pack has already made possible definite determination of the presence 

 of Merycodus in this region. Additional specimens secured by the 

 1915 party include a fragment of a lower jaw, a lower tooth, a num- 

 ber of fragmentary horn-cores, a scapula, and a second phalanx. One 

 horn-core specimen (no. 22332, fig. 17) resembles the type of Mery- 

 codus found in the Ricardo and Barstow faunas of the Mohave Desert, 

 and referred to M. necatus. Other portions of horn-cores, in which 

 the cross-section is nearly circular, suggests M. furcatus. The second 

 phalanx agrees approximately in size of corresponding parts with 

 the first phalanx described in the earlier paper. The single lower 

 tooth (no. 22366, fig. 16) is similar to or M T of a small species of 

 Merycodus from the Ricardo. On the basis of the Merycodus material 

 it is difficult to make a definite estimate of the age of the Chanac 

 fauna, but the Tejon Hills form might well represent a stage near 

 that of the Ricardo Pliocene.
