The dentition of Dinictw, like the skull, irresistibly suggests re- 

 lationship with the cats, and yet it still exhibits many important 

 primitive characters, of which may he mentioned the number of the 

 teeth, the large size of the upper molar and the presence of the in- 

 ferior tubercular ; the presence of a heel and of the posterior-in- 

 ternal cusp on the lower sectorial and the absence of the anterior 

 basal cusp from the upper sectorial. In these respects Dinictis de- 

 parts from the feline type and approximates the canine-viverrine 

 group.
