ANTHROPOLOGY OF ASIA 13 



platicephalism attains its maximum of frequency, that is 

 to say is more than f . To this zone we assign H. Asiati* 

 ens palceoarcticus 1 which is comparatively dolicho- 

 mesaticephalic, and H. Asiaticus altaicm which tends 

 more towards brachycephalism. The distinction how- 

 ever depends upon other differences and is based specially 

 upon a study of the now almost extinct Yenisseian tribes, 

 whom we conventionally call " Altaic." We put to- 

 gether the Samoyeds, Soyots and the Yenisseian Ostyaks 

 in a brachy cephalic sub- variety : Pal&oarcticus brachy- 

 morphus. 



Proceeding towards the south we find two zones of 

 clear and distinct brachycephalism : one represented by 

 Manchuria and by the contiguous maritime zone, the 

 other represented by central Asia. The whole of the 

 latter area however does not appertain to H. Asiaticus, 

 as we must separate from it the area inhabited by the 

 Galchas, the Tajiks and other kindred Pamirians, who we 

 maintain, differing from Sergi, have nothing of the 

 Mongolian in them. 2 These being left aside there re- 

 mains a nucleus of true Asiatics with ceph. ind. above 83 

 and with more than f of platicephals whom we put 

 collectively with the Manchus : both (that is to say, the 

 Manchus and the other Mongolians of Central Asia) 

 appear in our classification, conventionally, as H. Asiati- 

 cus centralis. 



Still further to the south there are prominent 

 two areas, Tibet and China (with Corea), both with a 



1 Really the Paleeoarctic zone is much more extensive and includes almost the 

 whole habitat of H. Asiaticus : it is useless to say that we have to do with denomina- 

 tions which have only a geographical approximation, for a mnemonic purpose.

 Sergi, which has been newly taken up by Frassetto and which I consider to be rather 

 misleading.
