Arc. 1897. Observations on Papuan Crania — Dorsby. 39 



Processes. — The mastoid processes are unusually will developed 

 in the males; poorly developed in the females. But even when they 

 reach their greatest development they by no means attain to the size 

 often found in American crania; they generally have a laterally com- 

 pressed appearance, and are frequently sharp pointed. The styloid 

 processes have all been destroyed. In many of the crania, especially 

 those of males, the comparative massiveness of the external angular 

 process forms a very striking feature of the face. 



Muscular Impressions.— Reference has been made, over and over 

 again, to the strongly marked temporal lines; they are almost without 

 exception well developed, and reach high up on the temporal bone 

 towards the vertex. The impressions for the masseter and external 

 pterygoids are also, as a rule, heavily moulded. In the male the 

 external occipital lines and protuberance are strikingly prominent. 

 In many cases the superior curved line forms a strong projecting 

 torus occipitalis transversus, in which inion is entirely overshadowed, 

 but in other skulls inion is prolonged into a large roughened projec- 

 tion. 



Summary. — The crania as a whole may be characterized as : 



MICROCEPHALIC, PROGNATHIC, 



DOLICHOCEPHALIC, MESOPROSOPK , 



METRIOCEPHALIC, MESORHIXE, 



• PH.^NOZVGOUS, MESOSEME, 



MHGAPONT (MBSODON I ).
