two crania referred to by Sir William Turner in his paper show 

 the same small number of brachycephalic skulls, and have an 

 average index of 74, a little lower than that given in this 

 paper. 



Vertical Index. 



The Ngaitaliu skulls are therefore metriocephalic. The 

 range of variation is 15-1. Of the thirty-eight in the table, ten, 

 or 26'3 per cent., are akrocephalic ; nineteen, or 50 per cent., 

 are metriocephalic ; nine, or 23-7 per cent., are tapeinocephalic. 

 The most northern of the North Island groups has again the 

 lowest index, almost tapeinocephalic. The average for both 

 Islands is the same as that for the Ngaitahu, and the grouping 

 of the skulls is as follows: Fourteen, or 19*2 per cent., are 

 akrocephalic ; forty-four, or 60'3 per cent., are metriocephalic ; 

 fifteen, or 20-5 per cent., are tapeinocephalic. The genei-al 

 average also shows that the male skulls, following the usual 

 rule, are slightly higher than the female. The comparatively 

 low indices, which we have just seen to be characteristic of 

 the Auckland skulls measured by me, are also shown by those 

 examined by Professors Flower and Turner from the same 

 district. The Whangarei skulls in the College of Surgeons' 

 Museum have an average index of 73-9, while that of Profes- 

 sor Turner's three is 71. The general average of the entire 

 set of thirty-three crania is therefore 73-2. Comparing the 

 cephalic and vertical indices, we find that in the Ngaitahu the 

 average cephalic exceeds the average vertical by 1-3, and in 

 the Auckland group by 0-5. In the other tv^'o groups from 

 the North Island the vertical exceeds the cephalic — in one 

 case by 0-5, and in the other by 0-2. The general average 

 gives a slight superiority — 0-8 — to the cephalic index. 



In sixteen Ngaitahu skulls (nine males and seven females) 

 the Basi-bregmatic height exceeds the viaximum transverse 

 width, while in twenty-two (fifteen males and seven females) 

 the width is greater than the height. The greatest excess of 

 width over height is in No. 6, Table I., where the height is 

 125mm. and the width is 141mm., giving a height-breadth
