NOTES ON THE CANID#Z OF THE WHITE RIVER OLIGOCENE. 329 
The tubercular molars are not preserved in the specimens of ? D. dodgei ; in D. vetus 
they are proportionately larger than in D. hartshornianus. M, is relatively large, 
especially in the antero-posterior diameter; it resembles the corresponding tooth of 
Canis, 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 Miacide, though in the 
White River genus all the cusps are lower and more tubercular. Mg is quite small, 
though both proportionately and actually larger than in species of Canis 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 Daphenus is that of a primitive member of the Canide 
and resembles the dentition of the recent members of the family in general plan and 
structure.
