NOTES ON THE CANID^E OF THE WHITE EIVEB OLIGOCENE. 



829 



The tubercular molars are not preserved in the specimens of ? D. dodgei; in D. velus 



they are proportionately larger than in J), hartshoriiianus. Mj is relatively large, 

 especially in the antero-posterior diameter ; it resembles the corresponding tooth of 

 Cams, except for the presence of the small paraconid, thus giving to the tooth all the 

 elements of a true sectorial, as is also the case in the creodont lliacidce, though in the 

 White River genus all the cusps are lower and more tubercular. M 3 is cpiite small, 

 though both proportionately and actually larger than in species of Cards of similar 

 stature, and is inserted by a single fang ; the crown is of oval shape and has an irregularly 

 ridged surface, without distinct cusps. 



As a whole, the dentition of Daphcemts is that of a primitive member of the Canidce 

 and resembles the dentition of the recent members of the family in general plan and 

 structure.
