 angular, sometimes conical, sometimes grooved 

 transversely on their cutting edges, as if bilobate, 

 and more or less distinct from each other. 



Canines more or less strong, conical, slightly 

 arched, and most generally proportional to the 

 size of the head, like those animals of the feline 

 race.
