 X 1. Bautista beds, California. 



The material indicates the presence of two or more Odocoileiis-Yike 

 species. 



The lower molars no. 23405 (fig. 5) are comparatively light and 

 low'-crowned, and the enamel is considerably crinkled. Two outer 

 buttresses, or styles, are present in Mg ; a single style in Mg. The teeth 

 differ from those of Odocoileus hemionus and 0. coliimbiana in the 

 presence of these two outer buttresses in the last molar, as in the 

 development of the single buttress of M2, which though generally
