Scott. — Osteology of the Maori and Morlori. 37 



Turner" and Mr. Arthur Thomson!, and it is worth noting 

 that, though this condition was found only thrice in the 1,037 

 skulls in the Oxford collection examined by this last observer, 

 yet one of these three skulls was from the Chatham Islands, 

 while another was a Maori. The third was an Andamanese ; 

 and Professor Turner's specimens were bushmen. In another 

 skull in my collection, in the left orbit, a triangular process 

 from the frontal bone and one from the orbital plate of the 

 superior maxilla api^roach each other between the os planum 

 and lachrymal to within a millimetre. This small interval is 

 filled by an ossicle distinct from both lachrymal and ethmoid. 

 In the right orbit of the same skull the ethmo-lachrjmial 

 suture is only l-|mm. in length. In two other skulls — right 

 orbit in one, left orbit in the other — the lachrymal bone is 

 absent, its place being taken by a backw^ard prolongation of 

 the nasal process of the superior maxilla, which articulates 

 with the OS planum. A somewhat similar condition occurs in 

 the right orbit of another skull, but two small ossicles are 

 present in this maxillo-ethmoid suture, which almost com- 

 pletely separate the bones from each other. In this same 

 orbit the frontal bone articulates with the orbital process of 

 the palate behind the os planum. In the left orbit of this 

 skull there is another modification of the same condition. 

 The broadened nasal process of the superior maxilla arti- 

 culates with the ethmoid behind ; but the articulation is 

 shortened below by the presence of an ossicle, which articu- 

 lates with the orbital plate of the superior maxilla. 



In the right orbit of another skull the osplanum is 

 divided into three parts. 



Alveolar Arch. — The curve is either parabolic or hyperbolic 

 in almost all the specimens examined ; but in three the molar 

 portions are parallel to each other, and the arch would be 

 classed by Broca as hypsiloid. In one skull there is a slight 

 incurvation of the premolar region. 



Loicer Jaiv. — The mandible is present in fourteen skulls, 

 and shows considerable variation as to the degree of rounding 

 of the angle and the character of the lower margin of the 

 body, some bones being of the ordinary European type in 

 these respects, others being convex from behind forwards, as 

 we have seen is frequently the case with this bone among the 

 Maoris. The coronoid exceeds the condyloid height in every 

 case except one, and in it the tw^o diameters are equal. The 

 bigonial width also exceeds the gonio-symphysial length in 

 every case. In one, however, these measurements differ by 

 only 1mm.
