The lower canine was set diagonally in the jaw. This is true of C. 

 lupus, but not to so great an extent, the anterior face of the tooth 

 presenting nearly as much outward as forward. The larger axis of 

 the root of Py is in the same direction. P 2"' 3^ ^^^ T have each a 

 larger posterior root and a smaller anterior one. The anterior in 

 P 2" and 3- is partly exterior to the posterior. The roots are closely

There are two mental foramina, a larger under P^^ and a smaller 

 one on a higher level beneath the anterior part of P^^. The posterior 

 portion of the lovver border of the mandible in front of the angle is 

 very convex antero-posteriorly. The anterior ridge of the ascending 

 ramus in front of the masseteric fossa is large and high and the fossa 



deep.
