the middle oues have broader crowns but are of a smaller 

 size than the outer ones. Anterior premolar at a little 

 distance from the canine, second premolar exactly between 

 the two other ones, third premolar close to the anterior 

 molar which forms with the other two molars a crowded 

 series; first and second premolar of nearly the same size 

 and shape, slightly slanting forewards; posterior premolars 

 and the three molars about equal in size and shape, with 

 narrow horizontal crowns. 



Lower jaw. Incisors very small, in pairs, on each side 

 the second just between the anterior one and the canine; 

 between the pairs a rather large interval. Anterior premolar 

 very closely to the canine, the second much nearer to the 

 third than to the anterior one; the interval between the 

 third premolar and the anterior molar is a little larger 

 than the small intervals between the three molars mutu- 

 ally; first and third premolar of about the same size and 

 shape, although the latter is slightly slanting forewards ; 

 the second premolar stouter developed, broader and higher, 

 with a large anterior cusp ; the three molars of equal size 

 remember strongly the uppermolars.
