F. SKULL FROM CALAVERAS COUNTY, CALIFORNIA (NO. 225178) 



(Plate xvni, a) 



The specimen, a skull of an aging male, is not deformed, and with the excep 

 tion of an exostosi s between the right inastoid and vaginal processes shows 

 nothing pathological. The various ridges and other features indicate strong 

 though not excessive musculature. The sagittal suture is occluded, and the 

 coronal, lambdoid, and several of the facial articulations show advanced physio 

 logical synostosis. 



The supraorbital ridges are pronounced, without exceeding the normal varia 

 tion in this respect among male Indians ; they extend over the median three- 

 fifths of the supraorbital space. The forehead is quite low and gradually slopes, 

 presenting subaverage frontal bend and eminences. There is but a slight 

 external metopic and sagittal crest, so that the outline of the transverse plane 

 of the skull superiorly is but little pointed. 



There is a moderate alveolar prognathism. The base presents several minor 

 anomalies, and the exostosis above referred to, which is probably the result of 

 a small tumor. The teeth are considerably worn off, but present nothing 

 abnormal in size or number.

G. SKULL FROM SANTA BARBARA COUNTY, CALIFORNIA (NO. 241912) 



(Plate xvm, I)) 



A small, but plainly masculine, skull, from an aging, not very muscular indi 

 vidual. It is damaged, but in no way deformed or diseased. The sagittal 

 suture is wholly occluded, a condition apparently somewhat premature, as the 

 rest of the cranial and facial articulations are still patent ; but this condition has 

 not affected the shape of the skull. 



The supraorbital ridges are pronounced, though not excessive for a male; 

 they are limited to the median two-thirds of the supraorbital space. The fore 

 head is very low and sloping, without distinct frontal bend or eminences. The 

 upper part of the frontal squama shows a quite prominent median ridge, which 

 broadens out as it proceeds backward and for a short distance is continuous
