from the same cause. The forehead is narrow and rather low : the cheek-bones are promi- 

 nent, but not very large ; the nasals large, prominent, and well produced. The chief indi- 

 vidual peculiarity of this skull is seen in the unusually long anchylosed stylohyals. It ia 

 edentulous, and the sockets of most of the teeth have been absorbed. 



5497. The atlas. 



Compared with that of the Australian (No. 5186), the zygapophyses are smaller, the di- 

 apophyses are larger, and the sub-bifurcate neural spine is better developed. The canals for 

 the vertebral arteries are larger, and they perforate the neural arch as well as the transverse 

 process. The neural arch is likewise perforated by the first spinal nerve. The characters of 

 age are manifested by the irregular ossification extending from the periphery of the odontoid 

 articular surface. 







5498. The axis. 



The diapophyses here are smaller, the bifid spine longer, and the transverse processes more 

 widely perforated and more produced, than in the Australian (No. 5187). 



5499. The third cervical vertebra. 



This, also, repeats the differences of the smaller zygapophyses, the larger articular canals, 

 and, the spine being bifid, with the two divisions well produced. 



5500. The fourth cervical vertebra. 



5501. The fifth cervical vertebra. 



The same differences are repeated in both these vertebrae as compared with those of the 

 Australian. 



5502. The sixth cervical vertebra. 



The body is proportionally larger and the costal part of the transverse process more pro- 

 duced than in the Australian. As an individual peculiarity, the neural arch and spine are 

 slightly distorted towards the right side, and the vertebral arterial canal of the same side is 

 contracted and divided by a transverse bony bar. 



5503. The seventh cervical vertebra. 



Both transverse processes are perforated. All the foregoing vertebrae to the axis inclusive 

 show characters of age by irregular ossifications extending into the anterior vertebral 

 ligament.
