Geelvink-Bay, in the East-end and on some parts of the North-coast. Brachycephaly is repor- 

 ted principally from the islands on the Western shore of the Papuan-Gulf: Kiwai, Goaribari, 

 (only 5 heads were measured ; this may be the cause of the somewhat fantastic looking figure 

 of 87) and the islands in the West part of the Torresstrait. Moreover there are the Mekeo 

 and the Hood-peninsula inhabitants with the high indices 82,9 and 83. 



Before drawing conclusions on thèse figures, we hâve to study the graphie représen- 

 tations of the head-lengths and -breadths and the resulting indices of various Papuan groups 

 together with those of the Negritoes, depicted in Diagr. XXVII, XXVIII and XXIX. 



The curves concerning the head-lengths and -breadths rather disappointed my antici- 

 pations; the ver}- - characteristic différence between mountain- and Bongko-Papuans of my 

 own diagram had induced me to count on more than thèse little striking configurations. 

 Nevertheless, by closer examination we might come to some conclusions. To facilitate com- 

 parison, I calculated first the relative average values — representing their percentage of the 

 standing-height — and brought them together in the following table, moreover completed 

 with the figures concerning the Bongko-Papuans, the Leitere-Papuans and the Arup.

The resuit is typical enough. The Timorini and the Torricelli-Papuans hâve a relative 

 headlength corresponding to that of the Tapiro-pigmies and the Negritoes. But the relative 

 headbreadths of both the latter are markedly larger, hence the tendency to brachycephaly. 

 The relative headbreadths of the New-Guinean mountain-tribes themselves are fairly concordant. 

 The measurements on the Mafulu produced a somewhat smaller length and a somewhat larger 

 breadth, from which resulted a higher index, but this déviation that in regard to the small
