170 DESCRIPTION OF TWO TASMANIAN ABORIGINAL CRANIA, 



temporal. The Pars glabellaris is of interest. Here the 

 outer table has weathered away, and no air cells or sinus 

 are to be made out. In this respect, the specimen differs 

 very materially from the more strongly developed cranium 

 from Eaglehawk Neck (A. (E.H.) 558), also described in 

 this paper. Sexual characteristics of the crania would 

 explain this at least in part. 



In spite of the absence of the cells, which might very 

 reasonably be assumed to have a considerable part in the 

 formation of the prominent glabella, this latter feature is 

 as typically marked as in the average Tasmanian skull. 



The mandible, recovered at the same time, wants por- 

 tion of the right ramus, and has been broken into two frag- 

 ments. This has since been restored. 



The great interest of this skull, apart from the locality 

 of its discovery, lies in the palate, together with the superior 

 and inferior dental arches. The teeth are perfect, all 32 be- 

 ing in position. The general conformation of the palate and 

 arches, with the tendency to elongation, and the parallel 

 nature of the alveolar borders are points of much interest. 

 (Plate XXIV.) 



It has already been noted that the extinct Tasmanian 

 race approaches more closely to the anthropoid apes than 

 other races do, in the arrangement of the molar teeth and 

 their tendency to be set in approximately parallel rows on 

 each side of the palate. Such characteristics are well shown 

 in the specimen at present under review. 



The following measurements are given : — 



Palato-maxillary, length* 64 mm. 



Measurements between cuter borders of 



3rd molars 61 mm. 



Measurements between outer borders of 



1st molars 57 mm. 



Combined length of molars and pre- 

 molars (R.) 48.5 mm. 



Combined length of molars and pre- 

 molars (L.) 47.5 mm. 



The whole palate has an excavated appearance, the hori- 

 zontal processes being deeply set. 

 Depth at 3rd molars 12 mm. 



*Margin of error in this measurement owing to the disintegration of 

 the process of superior maxilla, posterior to 3rd right molar.
