108 DESCRIPTION, ETC. OF SOME MALLICOLO CRANIA. 



The nasal aperture is fairly wide, and narrows very 

 gradually. The nasal spine is, as a rule, well marked, and 

 is double. 



In the skulls Nos. 1, 2, and 3, the malar bones are 

 prominent and massive ; they are less so in the remainder 

 of the skulls. 



In Nos. 5, 6, 7, and 8, the hollow under the malar- 

 maxillary suture is deep ; but, in Nos. 1, 2, 3, q-nd 4; it is 

 more shallow. 



The palate is parabolic in every case. 



SUTURES.— The Sagittal suture is simple in all the 

 skulls, with the exception of No. 1, where there is a 

 wormian bone. It is completely absorbed in No. 2 ex 

 ternally, but a trace of the suture can be seen on the 

 internal table. The coronal suture is simple except at 

 the pterion, where epipteric bones are present in several 

 of the skulls. This suture is absorbed in No. 2 below ^he 

 temporal ridge on both sides, and is very faint. 



In No. 3, it is absorbed on both sides below the tem- 

 poral ridge. The pterion is K-shaped in several of these 

 skulls ; in the remainder, it is H-shaped, or there is an 

 epipteric bone interposed. Wormian bones are present 

 in the lambdoidal suture in several of the skulls, and in 

 some in the p irieto squamosal suture. 



Two of the crania have an interpanetal bone. 



One of the skulls (No. 1) is metoj)ic. This condition 

 is more common among the Mallicolo than in other races, 



as in the Museum of the Royal College of Surgeons in 



London. One skull out of eight is metopic, and 



another shows traces of a frontal suture. Only one of 



these crania has a lower jaw complete This is small 



in all its measurements. The condylar height exceeds 

 the coronoid by 2m.m.
