Kuyubí language

Kujubim is a nearly extinct Chapacuran language spoken around the city of Guajará-Mirim in Rondônia, Brazil. The endonym, Kaw To Yo, may be the source of the river and synonym for this language, Cautario. Sources which list one do not list the other, so these may be the same language.
In addition, there is a language called Cumana, a possibly extinct variety of Kuyubí. Various names ascribed to the language in Campbell are Torá, Toraz, and Cautario, the last perhaps after the local river, and Abitana-Kumaná.
