tion of the sutures of the cranial vault, the degree to which this had taken place varying 
in different specimens. The tendency to bone formation in these Australian skulls, which 
gave rise to their weight and other peculiarities, affected also the condition of the sutures, 
so as to occasion obliteration at an earlier age than is the case in European skulls. No 
skull was metopic, but in the male youth indications of a frontal suture traversing the 
glabella were seen. Small Wormian bones were present in the lambdoidal suture in a 
few skulls, but there was no example of an interparietal bone. In several crania the 
spheno-parietal articulation was reduced to less than 5 mm. In three the squamous- 
tcmporal and frontal articulated directly at the pterion, either on one or both sides ; in
