animal matter, being generally in the same condition as skulls Nos. 

 1 and 2 from this region. 



The left mastoid and neighboring parts appear to have been cut 

 out by a rodent with broad teeth ; and there are also some cuts, most 

 probably gnawings, over the occipital bone and on the fore part of the 

 right temporal crest. 



A small depression, evidently a scar, 3 mm. high by 4 mm. broad 

 and 1 .5 mm. at greatest depth, is seen on the frontal, a short distance 

 above the most prominent part of the left supraorbital ridge. Fi'om 

 the depression run three small radiating lines, not fractures. 



The nasal process is ordinary and the nasal depression fairly well 

 marked. The glabella is medium, somewhat less prominent than 

 the ridges. The supraorbital ridges are of masculine proportions and 

 occupy the median two-thirds of the supraorbital space; above them 

 extends from side to side a shallow concavity. 



The forehead is rather .low, sloping backward from 4 cm. above 

 the glabella. It presents one broad median convexity; no lateral 

 eminences present. Above the convexity is a slight flattening, approx- 

 imately 4 cm. long, possibly the result of intentional compression. 



There is no medio-frontal and only a slight sagittal crest. The 

 parietal eminences are well-marked but diffuse. The outline of the 

 norma superior was a long ovoid. 



The temporal crests are not specially pronounced; the nearest 

 approach of that on the right to the sagittal suture is 5.7 cm. The 

 mastoids were rather large masculine. 



The occipital region is somewhat more prominent on the left and 

 the frontal bone on the right, so that the skull is moderately plagio- 

 cephalic. The occipital crest is pronounced, double-semilunar in 

 form. 



The auditory canals show partial occlusion by posterior and also 

 anterior exostoses, such as are quite characteristic, especially among 

 aged individuals, of the Peruvian Indians. 



The basilar process presents a small pharyngeal fossa; the rest of 

 the base is defective. The foramen magnum was in the usual posi- 

 tion. 



The sutures of the vault seem to have been quite well serrated ; the 

 sagittal is still plainly traceable outside as well as inside. 



Ventrally is seen a submedian metopic crest; there is a paucity, 

 with shallowness, of convolutional impressions.
