Gamela language
Gamela (Gamella, Acobu, Barbados)  Curinsi or Acobu, is an unclassified and presumably extinct language of the Maranhão region of Northeastern Brazil. It was originally spoken along the Itapecuru River, Turiaçu River, and Pindaré River, with ethnic descendants reported to be living in Cabo and Vianna in Maranhão State.

Kaufman (1994) said that 'only Greenberg dares to classify this language', due to the lack of data on it.

This is presumably the Gamela language of Viana for which 19 words are recorded in Nimuendajú (1937:68).
