About The Cover

The golden monkey Cercopithecus mitis kandti, a guenon of a rare subspecies that inhabits high-altitude forest in the area around the Virunga volcanoes of east central Africa. Its distribution coincides with that of the endangered mountain gorilla. The survival of both primates depends on the conservation of this relictual habitat.
