Alveolar Arch. — AH the skulls show the alveolar arch in 

 the parabolic form, although in No. 2 it approaches the form 

 of the letter U. 



Lower Jaw. — Only two of the skulls, Nos. 6 and 7, had the 

 interior maxilla. No. 6 is light, and the angle nearly a right 

 angle. No. 7 is much more massive and more rounded at 

 the angle. 



Teeth. — In none of the skulls are all the teeth present, 

 three have none at all. No. 3, the skull of a young man, 

 has remarkably good and ^ell preserved teeth, and. in this 

 skull the upper wisdom teeth are to be seen just breaking 

 through. In the other skulls such teeth as are present are 

 very much worn, but show no signs of decay. 



Classification. 



Cranial Capacity. — The average of the three Maori skulls 

 is 1392, thus placing them in the mesocephalic class. Pro- 

 fessor Scott's averages for 64 skulls of both sexes was 1420. 

 Of the Moriori skulls, two (Nos. 5 and 6) are in the micro- 

 cephalic class, and one (No. 7) is mesocephalic, the average 

 being 1310. This is very low, for the 38 skulls measured by 

 Professor Scott averaged 1416. One Moriori skull measured 

 by MM. de Quatrefages and Hamy gave 1785 cubic ceuti- 

 metres capacity. It will be noticed on my table that No. 7, 

 which was marked female on its museum label, but which I 

 mark " ?," has a much greater capacity than the two male 

 skulls. This is one of my reasons for doubtiug the accuracy 

 of its label. Professor Scott's highest capacity of a female 

 Moriori skull is 1358. 



Cephalic Index — The average of four Maori crania is 77*8, 

 or mesati-cephalic. The individual indices vary greatly, No. 

 3 (86*1) being very brachy-eephalie, and No. 2 (71 '3) dolicho- 

 cephalic. The average of these four crauia, owing to the 

 exceptionally high index of No. 3, is not a fair one, since 

 Professor Scott's average for 76 skulls is 75*4, and Sir 

 William Turner's for 72 skulls is 74. The mean of the 

 three Moriori crania is 761, or mesati-cephalic. Professor 

 Scott's mean for 40 skulls is 763, and Sir William Turner's 

 mean for eight skulls is 75*2. 



Vertical Index. — The average of the Maori skulls is 74*7, 

 or metrio-cephalic. The height is less than the breadth in 

 three out of the four skulls, and in the remaining one it is 

 greater. Turner's mean of 16 skulls was 73*5. Of the 

 Moriori, in two cases the breadth exceeds the height, and in
