groups are : Males — asterionic greater, eight ; Stephanie 

 greater, fifteen ; both equal, one. Females — asterionic 

 greater, six ; Stephanie greater, five. 



Index op Foramen Magnum. 



The large range of variation, 27, shows that the foramen 

 magnum has no very fixed proportions. The length is equalled 

 by the width in three cases. 



Orbital Index. 



The average index in the Ngaitahu group is mesoseme, 

 and the range of variation in it is 23-6. Of the thirty- 

 four Ngaitahu skulls measured, nine, or 23-5 per cent., 

 are megaseme; fourteen, or 44'1 per cent., are mesoseme; 

 eleven, or 32-4: per cent., are microseme. The proportion of 

 female skulls is greatest in the lower groups, and this low 

 orbital index in the female is worthy of note, as not being in 

 accordance with the generally-received view. Two of the 

 North Island groups have indices almost the same as the 

 Ngaitahu. The east coast skulls, however, have a lower 

 index, which brings them into the microseme division, but 

 there are not enough of these skulls in the series to lower the- 

 general average for both Islands below 86-1, in the mesoseme 

 group. Of the total sixty-eight skulls, seventeen, or 25 per 

 cent., are megaseme; twenty-nine, or 42-6 per cent., are 

 mesoseme; twenty-two, or 32-4 per cent., are microseme.
