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 reports from the mid-nineteenth century, particularly in the mountainous regions of the upper Ovenga (Doubanga) River, formerly the French Congo, now 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).
