Note the similarity in all details of Figs, i-ib and Figs. 2-26 ; and the 

 differences in Figs. 3-36 and Figs. 4-46 due to the much greater development 

 of the canines in the male (Figs. 4-46) than in the female (Figs. 3-36) , the differ- 

 ence in the size of the canines resulting, of course, in marked correlated differ- 

 ences in the depth and thickness of the distal half of the jaw.
