As to the individual features, the nasion depression is marked. 

 The situation of the nasion is ordinary, 1.1 cm. beneath the Hne con- 

 necting the highest parts of the borders of the orbits. The inter- 

 orbital width is moderate. The orbits themselves were rather small. 



The glabella prominence is well-marked, not excessive. The 

 supraorbital ridges are of moderate dimensions, but the whole supra- 

 orbital region protrudes somewhat forward and there exists a shallow 

 depression above it (2.8 cm. above the nasion). Yet this protrusion 

 does not constitute a real supraorbital arch; it is due to a somewhat 

 defective advance of the brain and consequently of the frontal 

 squama forward. The forehead itself is fairly well arched, but quite

low, a type often seen in skulls of Indians. The frontal eminences 

 are but slightly pronounced. There is no median crest. 



The sagittal region is oval from side to side, the parietal eminences 

 are well-marked, and the outline of the norma superior is accordingly 

 pentagonal. The temporal ridges are indistinct but run at a good 

 distance (between 5 and 6 cm. on each side) from the sagittal suture. 



The occiput is slightly protruding but the muscular ridges and 

 depressions tliereon are only moderate. The mastoids are of about 

 medium masculine size. 



The thickness of the bones of the skull is moderate.
