Upper incisors very strongly contrasted in size and form, the inner 
large with triangular crowns, higher than long, the front face convex, 
the inner face concave, and with distinct cingulum. Though far 
apart at root and apex, the inner incisors are strongly in contact where 
widest, that is at the base of their crowns. Outer incisor minute, 
rounded, flat crowned, barely extending beyond cingulum of canine 
and of inner incisor, between which it is closely wedged. The incisors 
thus completely fill the space between canines at level of cingula, 
though their roots and tips are wide apart, a very unusual condition,
