I. SKULL FROM SANTA ORU/ ISLAND, CALIFORNIA (NO. 241916) 



(Plate xx, a) 



An undeformed masculine skull. The sutures and teeth indicate a person 

 50 or somewhat more than 50 years of age. There is no trace of prematuiv 

 synostosis in any of the articulations. 



The supraorbital ridges extend over the median three-fifths of the supra- 

 orbital space and, while prominent, are not excessive. The glabella lies in a 

 small depression between the ridges. The forehead, low and sloping, presents 

 but moderate arching and mere traces of frontal eminences. The sagittal 

 region anteriorly is slightly elevated. 



The face shows a marked alveolar prognathism. The teeth are considerably 

 worn off and several have been lost through disease, which affected to some 

 extent also the left alveolar process, but there was apparently no anomaly of 

 number or conformation.

,T. SKULL FROM MOUND NEAR BAGLEY, WISCONSIN (NO. 207874) 



(Plate xx, 6)

 piece of each parietal. It was an adult masculine cranium. The sutures 

 are patent dorsally but obliterated ventrally, pointing to an individual of more 

 than 40 years of age.
