HEDLieKA] SKELETAL REMAINS OF EARLY MAN 255 



The tibiae were platycnemic. The right shows above the middle 

 a shaft of type 4 (nearly lozenge-shaped in section) and measures at 

 about the height of the nutritive foramen 3.8 by 2.3 cm.; tliis gives 

 the low index of 60.5. The form, platycnemy, and other features 

 agree well with those of Indian tibiae. 



Racial identification of the skeleton can not be arrived at definitely, 

 of course, from material so defective, but what there is all suggests 

 a common Indian. 



Critical Remarks on the Ovejero Region Finds 



The examination of the bones reveals nothing that even distantly 

 suggests the Negrito. It does not show the presence of two distinct 

 races; there is not enough properly to show even one. Wliat there 

 is agrees with the Indian. 



The formation in which the bones occur is plainly recent, partly the 

 effect of the floods, to which the nearby river, according to local in- 

 formation, is particularly liable, but mainly accumulation 1)y the 

 winds, which are said to blow across the valley protractedly and 

 occasionally with much force. However, this part of the problem 

 will be dealt ^vith by the geologist of the expedition. 



Notes on the Locality of Sotelo 

 By Bailey Willis 



The old Indian village of Sotelo is situated on the eastern or left 

 bank of the Rio Dulce near the boundary between the Provinces of 

 Tucuman and Santiago del Estero. There are a church and burying- 

 ground said to be more than a century old, and the locality was 

 inhabited long before these came into existence. Not far away is 

 Ovejero, where human remains were found in a superficial loess and 

 at Sotelo Doctor Hrdlicka found a skeleton, which he describes. 

 These notes deal with the aspects of the locality and of the forma- 

 tion in which the skeleton was discovered. 



The Rio Dulce is formed by numerous streams, which flow from 

 the Aconguija Range, that rises ^o a height of 3,000 meters in western 

 Tucuman. There are no notable tributaries from the east. In that 

 direction stretch the arid plains of northern Santiago del Estero, 

 covered with thorny desert bush and cactus. 



Near Sotelo the valley of the Rio Dulce is between 1 km. and 2 km. 

 wide and is sunk perhaps 5 m. to 10 m. below the plain. The right 

 bank of the river is a bluff which exposes a section of loess character- 

 ized b}'- a distinct pink color. Low bluffs of the same material face 

 the river plain locally on the left side near Sotelo, and the formation 

 appears to underlie the entire valley.
