Upper Teeth—The central incisors are very large, triangular, nearly fillmg the 
interval between the canines. The lateral incisors are minute, not over one-fourth the 
size of the centrals. The anterior surface is concave; the crown is blunt and quadrate, 
with basal cusp and cutting edge equal. The canine with anterior and posterior denticles, 
the posterior of the two being enormous and presenting the aspect of being an outshoot 
from the side of the crown. The first premolar minute and of the same form as the 
lateral incisor. The second premolar large, triangular and projecting beyond the molars.
