Tasniaiiiaii Crania. 51 



post-orbital diameter as compared with the maximum orbital 

 diameter, and which gives to all genuine Tasmanian crania 

 such a striking resemblance to that of the Neanderthal frag- 

 nient. All these signs were, with the exception of one sign in 

 one skull, present in the doubtful crania. 



In norma hderalis there is the uniformity in the recession of 

 the forehead which we carefuUr tested for by the ingenious 

 methods of Schwalbe, the arcus or torus supraorbitalis. the 

 deep depression of the nasion — all of which were easily recog- 

 nisable in the alleged spurious crania. 



In itoriiKt facialu thei'e is the platyrrhine nasal index, the 

 high position of the nasion relative to the orbits, the rect- 

 angular orbital outline and the parabolic palate — all of which 

 were present in the six crania with the exceptions of two 

 features, one from each of two skulls. 



Lastly, there were the highly characteristic cranial sutures, 

 the ossa suturarum, and the epipteric bones, the last being 

 present in two of the six —a high percentage — whilst the ossa 

 suturarum were present in no less than three of the doubtful 

 skulls. 



In our opinion, therefore, there can no longer be any reason- 

 iible doul)t that all six skulls rejected by Harper and Clarke 

 are undoubtedly those of absolutely pure-bred Tasmanians, and 

 we have therefore included them in our series, and we do so 

 with ever}^ confidence. 



We also discovered in the Hobart Museum fragments of three 

 other Tasmanian skulls which are incorporated in our v'ork. 

 This brings the total of Tasmanian crania in the Tasmnnian 

 Museum, Hobart, up to twenty, nine of which are now presented 

 to the scientific world for the first time. Had one of Harper 

 and Clarke's original twelve not disappeared, there would, of 

 c<..urse, be twenty-one. 



Sixteen other Tasmanian skulls were discovered by us in 

 Hobart. (M these, one was in the private possession of Inspector 

 Cook, two were in tlie possession of Mr. A. J. Taylor, chief 

 librarian of the Carnegie Library, Hobart, and thirteen were 

 in the possession of Dr. E. L. Crowther,. eleven of which were 

 first obtained during our visit to Hobart. The whole of these 

 .sixteen crania are now dealt with for the first time. Mr.
