Sub-divisions.—Of the Mataguayos. The Chaès (Qu.? Guanas), the Yoes, the Matacos, Begosos, Chunipis, and Oeolis.
Localities.—a. Of the Abiponians, the central parts of the Chaco, conterminous with b, the Mbocobis and Tobas conterminous with the Araucanians of Chili. c. Of the Lenguas, the central parts of the Chaco. d. Of the Payaguas, the banks of the Paraguay as far as its junction with the Parana, e. Of the Mataguayos, the parts between the Pilcomayo and Vermejo. f. Of the Mbayas, the eastern shore of the Paraguay.
The Guayanas.—I am unable to say how far this is the same tribe as the Chanès and Guanas.

Malbalaes, Mataras, Palomos, Mogosnas, Oregones, Aquilotes, Churumates, Ojotades, Tanos, Quamalcas,—probably extinct; at least they are placed by Dobrizhofer in the same category with the Calchaquis. Like the Calchaquis, also, they were equestrian.
