Hall 31. 
On one side of this hall are valuable collections from Vene- 
zuela and British Guiana. On the other side of the hall are 
collections from the Gran Chaco tribes. The most northern of 
the groups inhabit Brazil and Bolivia, while the more southern 
extend into the Argentine Republic. 
The principal tribes represented in the collections are the 
Toba, Lengua, Chamacoco, Guarani, Cuximoso, Pana, Paita and 
Omiri. The collections are especially interesting as representing 
tribes which have had but little contact with civilization.
