154 MAMMALIAN DENTITION 



In looking back over this short review of the Primate den- 

 tition in general the reader cannot fail to be impressed, as 

 the author has been, by the striking similarity shown in their 

 evolutionary progress by all families no matter at what stage 

 in ancestral Primate history these families have diverged. 

 Further he will realize how definitely parallel are the lines of 

 evolution in tooth forms presented even by diverse orders of 

 Mammals.
