The cranial index of my own 12 skulls averages 74,4, that of the 14 Biak-skuHs 75. — . 

 Only 2 skulls of the 26 are brachycephalic. This cranial index is markedly higher than that 

 of Meyer (Geelv. Bay, I. cran. 72,4), v. D. Broek (S.W. plains, I. cran. 72,15), Gray (Pap. 

 Gulf, I. cran. 72,2) a.o. ; on the other hand it is fairly corresponding vvith the cephalic index 

 of KOCH (Merauke-Pap., I. ceph. 75,5) and V. D. Sande (Sentani-Lake, I. ceph. 75,68). 



It deserves attention that crania n° 6 and 7, brought by the Papuans themselves, were 

 decorated with red lines — in one case red ocre vvas evidently used — . This is the more 

 remarkable, as a similar adornment (?) is also found sometimes in the European prehistoric 

 graves. In n° 6 were six, in n° 7 eight lines radiating from the obelion, and they were 

 crossed by resp. four and six circular lines round the crown. In n° 6 there were moreover 

 red circles round the eye-holes. 



Finally I will not leave off mentioning that Dr. DE ROOK found a skull amidst other 

 human bones under a stone on the Doormantop (3550 M.) in quite unhabited country. Only 

 the calotte was sent to Europe as the other bones were entirely time-worn. 



The cranial index of this skull appeared to be 66. — , (length 18,95 cm., breadth 12.5 cm.) 

 so it is highly dolichocephalic. This increases the chance of being a Papuan skull. Yet it is 

 not the most dolichocephalic of the Papuan skulls of the Amsterdam Colonial Institute : there 

 is one that with nearly the same length has a still smaller breadth , what results in a 

 cranial index of 63,3 (length 18,8 cm., breadth 11.9 cm.).
