NOTES ON THE SIOUX 



The skulls of the very interesting and important group of the Siouan 

 tribes show the following basic conditions: 



1. The Siouan family embraces somatologically (a) what may be 

 termed the Sioux proper; (b) physically closely related tribes; (c) 

 physically less closely related groups; and (d) tribes related only in 

 language. As far as our data go, the tribes belonging to these several 

 subdivisions are given in the preceding summary. 



2. The Sioux type, one of the best differentiated of Indian types on 

 the continent, is characterized by: 



A skull of moderate to good size; 



Mesocephaly; 



A remarlmhle lowness of the vault; 



Large face (and jaws); 



Medium-high orbits; and 



Mesorhynic nasal aperture. 



3. The lowness of the vault is a highly distinctive feature, which in 

 larger bodies of the North American natives north of Mexico is met 

 with onty among the Athapascan and related northwest coast tribes, 

 and more distantly among the Mongols of Asia. 



4. The Osage are plainly not Sioux, regardless of language and 

 possibly some admixture. This conclusion is seconded by observa- 

 tions on the living.
