HAWAIIAN SKULLS 



per cent.) mesaticephalic, and only one (No. 1 104 H. U.) is dolichocephalic. 

 This skull is described under the head of Diseased Action as an example of 

 change in skull-form, due to disease. Turner's cave series were all brachy- 

 cephalic. The coast series, on the contrary, exhibit fifteen (fifty per cent.) 

 brachycephalic, ten (thirty-three percent.) dolichocephalic, and five (seventeen 

 per cent.) mesaticephalic. The Oahu series of Turner exhibited seven brachy- 

 cephalic, eleven mesaticephalic, and fifteen dolichocephalic. 



ALVEOLAR INDEX. Of the cave series, eight (twenty-seven per cent.) are 

 orthognathous, sixteen (fifty-five per cent.) mesognathous, and five (seventeen 

 per cent.) prognathous. In the Turner crania two were mesognathous and 

 two were orthognathous. In the coast series thirteen (fifty per cent.) are 

 orthognathous, nine (thirty-four per cent.) mesognathous, and four (fifteen per 

 cent.) prognathous. In Turner's Oahu series seven were orthognathous, six- 

 teen mesognathous, and three prognathous. 



ORBITAL INDEX. The orbital index exhibits in the cave series twenty- 

 four (ninety-two per cent.) megaseme, two (eight per cent.) mesoseme, and 

 none microseme. Turner's conclusions are practically the same. In the coast 

 series there are no examples which are not megaseme. This statement is of 

 interest, since Turner regards the Oahu crania to be mesoseme. 



NASAL INDEX. Of the cave crania, ten (thirty per cent.) are leptorhine, 

 seventeen (fifty-one per cent.) mesorhine, and six (eighteen per cent.) platy- 

 rhine. This series embraces skull 1753 H. U., which has a very well pro- 

 nounced prenasal fossa. It is doubtful in what manner skulls having this 

 peculiarity should be measured for this index, since the limitation for height 

 is a difficult matter to determine. It may be well to say, in taking the meas- 

 urement, I selected the nasion for one point, and the top of the incisor crest 

 as the second. Of the coast series, five (sixteen per cent.) are leptorhine, 

 fifteen (fifty per cent.) mesorhine, and ten (thirty-three per cent.) platyrhine. 

 According to Turner, in the cave series two were mesorhine and two lepto- 

 rhine, and of the Oahu crania, three were platyrhine, six mesorhine, and two 

 leptorhine. 



By the vomerobregmatic height (see Florida Skulls, 2 p. 412) I denote the 

 distance between the bregma and the alas of the vomer as they join the body 

 of the sphenoid bone, to indicate (when this measurement is compared to the 

 basibregmatic) the degree of inclination of the basilar process. It must be con- 

 ceded, however, that this height may measure the degree of depression of the 

 bregma itself. I do not consider it, therefore, a measurement of great value.
