 5811. The cranium of a male Australian. 



The alveolar part of the upper jaw is more than usually produced : the alisphenoid joins 

 the parietal on both sides. There is a supramastoid ridge, below which is the narrow fissure 

 and ridge indicating the outer extremity of the anchylosed tympanic.

5312. The cranium, wanting the right temporal bone, of an Australian. 



The alisphenoid joins the parietal on both sides of the head. The last true molar is not 

 fully developed on the left side, and near it is a small supplementary tooth, in a distinct com- 

 partment of the alveolus. The paroccipital prominences are well marked. 



Hunterian. 



5313. The cranium, wanting most of the teeth, of an Australian. 



A small portion of the left alisphenoid joins the parietal ; on the right side a wormian 

 bone intervenes, which seems to be rather a dismemberment of the squamosal. The right 

 jugular fossa is disproportionately large. 



Hunterian. 



5314. The skull of an Australian from the Western coast. 



A small portion of the alisphenoid joins the parietal on both sides of the head. The supra- 

 mastoid ridge is strongly developed on the right side. The suborbital fossae are deep.

5315. The cranium of a female from ' Port Fairy,' in the Port Phillip district. 



The squamosals join the frontals on both sides : a small wormiaii bone is partially inter- 

 posed on the left. The parietes of the cranium have been injured, apparently after death.

5316. The skull of an Australian. 



The right anterior incisor has been removed during life, and the alveolus is obliterated. 

 The apex of the narrow alispheuoid just reaches the parietal on both sides of the head. The 

 roots of the teeth are exposed on the right side, showing the outer root of the premolars to 

 be single, that of the large true molars double, in both jaws.

5317. The cranium, vertically and longitudinally bisected, of an Australian, from 

 Port Essington. 



This is unusually compressed and arched from before backwards : the squamosal joins the 

 frontal on the right side ; a wormian bone is interposed on the left. The right suborbital 

 fossa is deep : the supramastoid ridge is strongly developed on both sides. The parietes of
