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 base 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. 241997) 
(Plate x1x) 
A symmetrical, nonpathological skull of a male of about 50 years of age. 
There is advanced occlusion in the sagittal, and some synostosis in the lamb- 
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 zygome, with other features of the skull, 
indicate strong musculature. The teeth present nothing special. The base is 
free from anomalies of any importance.
