along the sagittal suture. On account of this ridge the arch of the transverse 

 plane of the skull is moderately pointed. 



The temporal ridges are fairly well marked, but the muscular impressions and 

 ridges on the occiput are weak. 



The face shows a moderate grade of alveolar prognathism. The teeth are not 

 large and present no anomaly. 



The hase shows on the left side one complete (proximal) and one slightly in 

 complete (distal) pterygo-spinous foramen or fenestrum, both formed on the 

 median side of the foramen ovale.

H. SKULL FROM SANTA CRUZ ISLAND, CALIFORNIA (NO. 241927) 



(Plate xix ) 



A symmetrical, nonpathological skull of a male of about 50 years of age. 

 There is advanced occlusion in the sagittal, and some syuostosis in the larnb- 

 doid suture, but all the other articulations are still patent. The condition 

 of the teeth, which are somewhat worn, corresponds well to the state of the 

 sutures, so that any premature ossification of the latter may be excluded. 



The supraorbital ridges (limited to the median half of the supraorbital 

 space) are of average masculine proportions and the same statement applies 

 to the glabella, yet the forehead is low and sloping, presenting only a very 

 moderate arching and no eminences. The region just anterior to the bregma 

 and along the proximal half of the sagittal suture shows a well-marked eleva 

 tion, which gives the skull a scaphoid appearance. 



The face shows a medium grade of prognathism, and somewhat atypical, 

 not very large nasal gutters. The zygoma?, with other features of the skull, 

 indicate strong musculature. The teeth present nothing special. The base is 

 free from anomalies of any importance.
