Dongos
Dongos (Matimbos), a small people of equatorial Africa, north-east of the Tobbi country, and north of the Sette river. Like the Abongos of the Ogoway basin they appear to be a surviving branch of the primitive pigmy element, fragments of which are still met under various names scattered over a vast area in the interior of the continent (Oscar Lenz).
