36 Transactions. — Zoology. 



have been frequently seen among the Morioris, should be 

 remembered in this connection. It must not be supposed, 

 however, that this form of nose is peculiar to the Morioris 

 among Pacific Islanders. Such noses are not uncommon 

 among the Maoris of some districts of New Zealand, and Pro- 

 fessor Moseley '■' states that they occur to the extent of 5 or 6 

 per cent, among the Admiralty Islanders. 



Loiver Margin Anterior Nares. — In twenty skulls this is 

 rounded ; in thirteen sharp, as in Europeans ; in six the 

 margin is doubled ; while in four it is bevelled off. 



Infra-orbital Suture. — In a large number of skulls this 

 suture is present, either complete or partially obliterated. It 

 was noted as present on both sides in twenty-one skulls. 



Third Condyle. — Though no true example of this condition 

 was observed, in one skull a smooth articular surface was 

 present on the anterior margin of the foramen magnum. 

 This was probably caused by the rubbing of the tip of the 

 odontoid process. 



Lachrymal Bone. — Unfortunately, owing to the broken 

 state of the inner wall of the orbit in many of the skulls, I 

 was unable to determine the nature of the articulations in 

 this region in more than a few cases. In some of these, the 

 only peculiarity is a marked shortening of the ethmo-lachrymal 

 suture. In one this is reduced to 5mm., in another to 4mm., 

 and in another to l^mm. But six skulls shovr peculiarities 

 which, I think, merit special notice. In the first, the lachry- 

 mal bone of the right orbit is a narrow, delicate, curved plate, 

 separated from the frontal by a narrow neck of bone connect- 

 ing the OS planum with a backwardly prolonged nasal process 

 of the superior maxillary. In front of and behind the lower 

 part of this rudimentary lachrymal are spaces which w^ere 

 probably at one time filled by additional ossicles. Behind this 

 the orbital process of the superior maxilla sends a triangular 

 process upwards to within 2mm. of the frontal bone. In the 

 left orbit of the same skull the lachrymal is still further 

 reduced, and a similar process of the superior maxilla passes 

 up between the nasal process and the os planum, and articu- 

 lates with the frontal bone. In another skull (left orbit) there 

 is no separate lachrymal bone, but its place is taken by the 

 extension backwards of the nasal process of the superior 

 maxilla, behind which a broad triangular process of the 

 frontal passes down, completely separating it from the os 

 planum, and articulating with the orbital surface of the 

 superior maxilla. My collection, therefore, shows two ex- 

 amples of the rare orbito-maxillary-frontal suture. This 

 articulation has been described and figured by Sir William
