Kooloo-kamba

Kooloo-kamba (or koola-kamba) is an appellation for a species of hominid, compared to the chimpanzee (P. troglodytes), which was said to exist in central Africa in mid-nineteenth century reports from the mountainous regions of the upper Ovenga (Doubanga) River, in what would become the French Congo in subsequent decades, and is today part of Gabon. The species is so-called for its distinctive cry of "kooloo," as described by Paul B. Du Chaillu in his book Explorations and Adventures in Equatorial Africa (1861).
