I.—SKULL FROM SANTA CRUZ 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 premature 
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.

(Plate xx, 0) 
The only portions remaining of this specimen are the frontal bone and a small 
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.
