that this migration to the islands of the Pacific could 

 have taken place only in very ancient times when, China 

 being almost uninhabited, it would have escaped the 

 contamination of type. If this hypothesis takes us back 

 to an epoch in which central Asia was not yet divided 

 between the Leucoderms and the Xanthoderms, when these 

 types perhaps had not yet come into existence, then we 

 have still greater reason on our side to consider the 

 Ainu as an archeomorphous (this term is preferred by 

 Bonarelli) relic, without actual systematic affinity. 



Probably the two subdivisions of ff. Indonesiac'ts, 

 made according to the approximate indication derived 

 from the cephalic index, are not sufficient and one 

 ought to examine the other characters, as we have 

 done for H. Asiaticus ; the nasal index specially shows 

 too great oscillations which might be distributed into 

 several minor groups. It would be desirable that 

 the large islands of Indonesia were subjected to an 

 extensive anthropological survey like that splendid one 

 that Great Britain has made in India, and as the United 

 States are doing for the Philippine Islands. The measure- 

 ments of Hagen are hardly useful he takes the nasal 

 length on the ridge of the nose and also the high nasal 

 ndex found by Kohlbrugge among the Tengerrese 

 would require to be confirmed. 



In Summary IX those islanders that have the characters 

 of Homo Asiaticus are not included, since they would be 

 out of place, such for example, as many natives of the 

 Philippines, and so also the natives of Formosa. On the 

 contrary many of the Formosans and likewise the Igorots of 

 Luzon are considered by Hrdh^ka 1 as good representatives 

 of the primitive yellow type. The Igorots are shown
