The Apolistas took their name from the river Apolo, an affluent of the Beni, about south latitude 15°. They were contiguous to the Aymaras, and had some physical resemblance to them. From their position, I suspect they belong in the Tacana group.

The Chapacuras, or more properly Tapacuras, were on the Rio Blanco or Baures in the province of Moxos. They called themselves Huachis, and the Quitemocas are mentioned as one of their sub-tribes. Von Martius thinks they were connected with the Guaches of Paraguay, a mixed tribe allied to the Guaycuru stock of the Chaco. The resemblance is very slight.

The Covarecas were a small band at the mission of Santa Anna, about south latitude 17°. Their language was practically extinct in 1831.

The Curaves and the Curuminacas, the former on the Rio Tucubaca and the latter north of them near the Brazil line, were said to have independent languages; but both were extinct at the time of D’Orbigny’s visit in 1831. The same was true of the Corabecas and Curucanecas.

The Ites or Itenes were upon the river Iten, an affluent of the Mamore about 12° south latitude. They were sometimes improperly called Guarayos, a term which, like Guaycurus, Aucas, Yumbos and others, was frequently applied in a generic sense by the Spanish Americans to any native tribe who continued to live in a savage condition.

The Movimas (Mobimas) occupied the shores of the Rio Yacuma, and Rio Mamore about 14° south latitude. In character and appearance they were similar to the Moxos, but of finer physique, “seldom ever under six feet,” says Mr. Heath. They are now civilized, and very cleanly in their habits. The vocabularies of their language show but faint resemblances with any other.

The Otuquis, who in 1831 did not number over 150 persons, lived in the northeast part of the province of Chiquitos near the Brazilian line. Their language was nearly extinct at that time. The short vocabulary of it preserved by D’Orbigny does not disclose connections with other stocks, unless it be a distant affinity with the Tacana group. This may be illustrated by the following words:

OTUQUI.TACANA DIALECTS.
Man,vuani,reanci.
Woman,vuaneti,anu.
Sun,neri,ireti.
Moon,ari,bari.
Water,uru,yuvi.
Head,ikitao,ekuya.

It was the policy of the Jesuits in their missions in this district to gather the tribes from the forest and mountain into permanent settlements, and reduce as far as possible the number of languages and dialects, so as to facilitate instruction in religious teaching. Shortly after this Order was expelled from their missions (1767), an official report on their “reductions” was printed in Peru, giving a list of the tribes at each station, and the languages in use for instruction.[481] From this scarce work I extract a few interesting particulars.
