5324. The cranium, vertically and longitudinally bisected, of a male Tasmanian. 



The characteristic thickness of the cranial walls is unusually well marked, with the absence 

 of the frontal sinuses. The alisphenoid joins the parietal on the left side ; a wormian ossicle 

 is interposed on the right side. The styliform process of the sphenoid is well developed, 

 and is applied against a ridge of the petrosal. The premaxillary suture may be traced from 

 the palate along the incisive foramen into the nostril. The contiguous parts of the second 

 bicuspis and first molar of the left upper jaw are decayed, which is a rare circumstance in 

 this race. 



Hunterian. 



5325. The cranium, vertically and longitudinally bisected, of a male Tasmanian. 



The alisphenoid joins the parietal on both sides of the head : the frontal protuberances are 

 filled with a cancellous diploe. The teeth have been much worn. 



Presented by Ronald Gunn, Esq. 



5326. The cranium of a female Tasmanian. 



The right last molar has not come into place. The right alisphenoid joins the parietal : a 

 wormian ossicle is interposed on the left side. The worn crown of the first true molar well 

 indicates the early period at which this tooth of the permanent series comes into place. The 

 paroccipital tubercle is well developed, especially on the right side. 



Hunterian. 



5327. The fore part of a vertically and transversely bisected cranium of a female 

 Tasmanian. 



A wormian bone is interposed between the alisphenoid and the parietal on both sides of 

 the head. 



Presented by Ronald Gunn, Esq. 



5328. The cranium, with the zygomata fractured, of a male Tasmanian. 



The teeth have been worn down to the stumps. A section has been made across the frontal 

 protuberances, showing that the sinuses have extended into them. 



Presented by Dr. Hobson. 



5329. The cranium of an Australian. 



It has been stained of a black colour, showing well, by contrast, the enamelled crowns of 

 the characteristically large molars and premolars. A wormian ossicle is interposed between 

 the alisphenoid and parietal on both sides. 



Presented by Ronald Gunn, Esq. 



5330. The cranium, wanting the lower jaw, of an Australian of Port Essington. 



The apex of the alisphenoid joins the parietal on the left side ; a wormian bone is inter- 

 posed on the right. The eustachian processes of the petrosal are remarkably developed in 

 this skull.
