it is broad. Indeed, if we look at the measurements of the 

 individual skulls, we find that in only two (Nos. 22 and 29) 

 does the height exceed the maximum width, and then only 

 by two millimetres in one case and by one in the other, 

 while in two skulls more these diameters are equal. In one 

 skull (No. 11) this excess of breadth over height amounts to 

 18mm., giving a height-breadth index of 88. 



In this respect the Moriori skulls differ distinctly from the 

 Maori. As will be seen by referring to the earlier part of this 

 paper, the average vertical index in Maori skulls is 74-6 — ■ 

 slightly lower than the cephalic index, which is 75-4. In them 

 there is an excess of the cephalic index over the vertical of 0-8. 

 In the case of the Morioris, however, the excess is 3-6. It is 

 true that there are several Maori skulls given in the tables 

 whose vertical indices are lower than the Moriori mean, but 

 there is no Maori skull with an index as low as the lowest 

 Moriori, nor no Moriori as high as the highest Maori. Also, 

 in over 90 per cent, of the Moriori skulls the width is greater 

 than the height, while in only from 40 to 50 per cent, is this 

 the case with the Maori skulls that I have examined. 



The highest cephalic index and the highest vertical index 

 belong to the same skull, and there is a general correspondence 

 betwean these indices throughout the series. 



Professor Flower's series have again a higher index than 

 mine — 73'9 — because of the measurements selected ; and 

 Professor Turner's have an average of 73. I have not cal- 

 culated this index for the "Novara" skulls, as the height 

 given is not the basi-bregmatic ; but the mean index of those 

 in the Paris Museum is 72-8. 



The average basi-bregmatic height of the male skulls that 

 I have examined is 135-5mm. ; of the females, 128-lmm. ; 

 while the combined average is 133-7mm., showing an excess 

 of breadth over height of 6 •4mm. 



Frontal Index. 



The range of variation is here 16"4. 



In my series of Maoris this index averages 68-1. The 

 anterior narrowing of the cranium is therefore more pronounced 

 in the Moriori than in the Maori. 



In the forty skulls in which it was possible to compare
