xlvi Proceedings. [May 30th; 1916. 



belong to divergent species, and perhaps genera, which can be 

 grouped together as belonging to a Palceanthropic Age, which 

 gave place (at the end of the Monsterian epoch in Europe) to a 

 Xeoa?ithropic Age, when men of the modern type, with higher 

 skill and definite powers of artistic expression, made their 

 appearance and supplanted their predecessors. 



So long as primary importance continues to be assigned to 

 the terms Palaeolithic and Neolithic the perspective of anthro- 

 pology will be distorted. 



Though the facts I have enumerated in this communication 

 are widely recognised, one finds that the writers who frankly 

 admit them lapse from time to time into the mode of thought 

 necessarily involved in the use of the terms Palaeolithic and 

 Neolithic. If modern ideas are to find their just and unbiassed 

 expression some such new terminology as is suggested here 

 becomes necessary.
