62 BULLETIN OF THE ESSEX INSTITUTE. 



Norma posterior. — The skull is hypsicephalic or nar 

 row and high, but not to an extreme degree as is usually 

 the case with Australian skulls. The region just above 

 the occiput and below the parietal eminences is slightly 

 flattened. The transition of the posterior region is very 

 marked at the region of the inion where the occipital bone 

 passes forward very abruptly. 



Norma inferior. — While the external occipital crest 

 is fairly prominent, no trace of the inferior curved line 

 can be made out. The digastric and occipital grooves are 

 very deep and pronounced and the foramen ovale seems 

 to be of unusually large size. The zygomatic arches stand 

 out prominently and the prognathism already spoken of 

 is seen in the distinct forward slant of the alveolar process. 

 The surfaces of the alveolar process are broad and are 

 more or less absorbed, especially in the regions of the in- 

 cisors.
