Procolobus verus (olive colobus)

Synonyms: Colobus chrysurus; Colobus cristatus; Semnopithecus olivaceus

Wikipedia Abstract

The olive colobus monkey (Procolobus verus), also known as the green colobus or Van Beneden's colobus, is a species of primate in the Cercopithecidae family. Its English name refers to its dull olive upperparts. It is the smallest example of all colobine monkeys and is rarely observed in its natural habitat because of its cryptic coloration and secretive nature. It is found in the rain forests of West Africa, ranging from southern Sierra Leone to Nigeria.
