formed skulls, showing clearly the cranial type of the people, were 

 encountered in every cemetery. An interesting fact is that there were 

 found dispersed in the valley seven skulls, mostly of women, with 

 a typical Aymara deformation. Whether these were slaves or indi- 

 viduals introduced in other manner among the Huacho people, and 

 whether pre-Columbian or post-Columbian, could not be determined. 

 None the less the occurrence shows that the Huacho Valley people 

 came into contact with individuals of the Aymara culture. 



Several specimens of special or collateral interest were found in 

 this valley. One was a clearly syphilitic skull, and four evidently 

 tuberculous bones. The period, however, to which these bones 

 belonged could not be ascertained and it is quite possible that they 

 were fairly recent. The rarity of fractures was very remarkable. 

 Some of the skulls showed injuries by stones or clubs, but there 

 were no trephinings. And there existed, doubtless due to strong 

 development of the occipital tendons and muscles, an unusually 

 large percentage of impressions (physiological) in the occipital at 

 the inion. 



So far as cultural objects are concerned, the pottery of the 

 Huacho Valley, outside of some specialties, seems well to represent 

 the more ordinary pottery common to the coast. There are, how- 

 ever, cemeteries which yield a better class of earthenware than 

 others, and a few forms were seen which may be peculiar to this 

 region. Besides pottery the people also made oblong moderate- 

 sized palm baskets, which were occasionally buried with the dead, 

 filled with utensils and materials for sewing and weaving. There 

 were evidently few, if any, high class fabrics ; but the ordinary 

 weaving presented some local peculiarities, one of which was the 

 frequency of network stuffs. 



The caves at Quintay, distant about 50 kilometers from the 

 coast and already well in the mountains, showed still a predom- 

 inance of skulls with the fronto-occipital deformation, but about 

 one-fourth of the crania presented undeformed oblong forms, such 

 as those met with in the Huarochiri highland district farther south. 



According to information obtained from various sources, con- 

 siderable quantities of skeletal material lay exposed in the vicinity 

 of Supe, about 32 kilometers in a straight line north of Huacho, and 

 especially on the grounds of the hacienda Paramonga, in the neigh- 

 borhood of Supe, but these regions could not be visited on this oc- 

 casion.
