These twelve male pelves are, on the whole, both narrower 

 and shallower than the average pelvis of the European male, 

 but the height is proportionally to the breadth slightly greater 

 in the Maori, as is seen by comparing the height-breadth 

 index in the two races. The average male index, as given by 

 M. Verneau, in Europeans is 79. 



The female Maori pelvis, so far as shown by the fourteen 

 now described, is also narrower tlian that of the European 

 female, but is its equal as to height. It has therefore a 

 higher index, that of the European female being 74 according 

 to M. Verneau, 75 according to Dr. Garson. 



In both sexes, then, but to a slightly greater extent in the 

 female than in the male, the Maori pelvis is higher relatively 

 to its width than is the case with the majority of Europeans. 



The following table, arranged like the last, gives the 

 average measurements and index of the brim of the lyclvis : — 



The figures show that while the two diameters of the 

 brim are, as is always the case, longer in the female than in 

 the male, yet that the proportion between them is much the 

 same in the two sexes, the female showing a slightly greater 

 proportional length in the sagittal diameter. 



It is curious that both the highest and the lowest index 

 should be found among the female pelves. The maximum 

 index, 102-3, does not, however, belong to a pelvis with an 

 unusually short transverse diameter. On the contrary, this is 

 128mm., a little above the female average. It is the great 

 length of the antero-posterior measurement which is the cause 

 of tliis exceptionally high index. This is the only pelvis of 

 either sex in which the antero-posterior diameter of the brim 

 exceeds the transverse. 



Professor Turner's two male pelves have higlier brim 

 indices than of any of my males. In one the index is 97, 

 and in the other it is 95. Even allowing for the fact that 

 Professor Turner measures to the back of the upper end of 

 the sympliysis, the indices show tliat in these two pelves the 

 conjugate diameter is longer proportionally to the trans- 

 verse than in any of the male pelves that I have measured. 

 Including these two pelves with mine, we get an average
