OF THE MICMAC SKULL CAMERON. 



19 



diameter and the maximum parietal breadth were actually 

 slightly greater in the Piltdown specimen (112 m m., and 150 

 m m., respectively). The maximum Piltdown cranial length 

 was, however, 190 m m., as compared with 182.5 mm., which 

 of course detracted slightly from the breadth when both 

 crania were drawn to the same scale. 



Fig. 5 exhibits outlines of the Micmac skull andaMelane- 

 sian skull, drawn to the same scale and viewed from above. 

 The Melanesian cranial contour is represented in dotted 

 outhne and is seen to be comparatively deficient in all its 

 transverse dimensions, but particularly so in the region 

 of the post-orbital constriction. Indeed it compares un- 

 favourably to a shght degree even with the Neanderthal 

 calvaria (Fig. 3) and in common with that, exhibits the 

 prominent supraorbital ridges which project well beyond 

 the line of the Micmac frontal contour.
