permit of any conclusions being drawn from their measure- 

 ments, it may, however, be of interest to note that their 

 average scapular index is higher than that of the males, in this 

 respect resembling European bones. 



The scapulae examined vary in their length from 174mm. 

 to 142mm., and in breadth from 119mm. to 90mm. The 

 mean length is 156-9mm., aiid the mean width 102mm. 

 The average scapular index is 64-9 ; the extremes are 70-6 and 

 60. There is practically no difference between the bones of 

 the two sides in this proportion. The average infra-spinous 

 index is 89-4. The extremes are 100 and 72-4, showing that 

 in the Maori, as in other races, there is great individual varia- 

 tion in the position of the spine. In Sir William Turner's 

 " ' Challenger ' Report " " he gives the indices of a Maori scapula 

 from Otago. In this bone the scapular index is 63-9, and 

 the infra-spinous 88-5. M. Livonf has measured thirty-two 

 Polynesian scapulae, but how many of these are Maori I 

 cannot say. He gives the scapular index as 66'6. 



The broadest scapulae seem to belong to the Andaman 

 Islanders, whose index is 70-2 ; the narrowest to the Tas- 

 manians, with an index of 60-3 ; while the average index of 

 65-3 shows the European bone to be slightly broader than 

 the Maori. 



The scapulae were also examined with reference to the 

 condition of the supra-scapular notch. In seven bones no 

 notch is present, and the upper border forms one continuous 

 concavity from the upper angle to the base of the coracoid 

 process, while in several others the notch is very shallow. 

 In no case did I notice ossilication of the supra-scapular 

 ligament. 



Clavicle. 



The length was taken in a straight line between the ex- 

 tremities of the bone, I have measured twenty-nine clavicles 

 — fourteen belonging to the right side, and fifteen to the left. 

 The average length of the entire series is 143'3mm. — that of 

 the right bones 141-5mm., of the left bones 144-9mm. This 

 excess in length of left bones over right was also observed in 

 the clavicles of the eight skeletons in which I was able to 

 compare the bones on the two sides. In seven of these the 

 left was the longer bone, and in the eighth the right exceeded 

 the left by only 1mm. The maximum length observed is 

 171mm. ; the minimum 130mm. 



The condition of the subclavian groove was looked at 

 in each case. It is almost invariably shallow and in- 

 distinct.
