We describe the banding patterns of the chromosomes of Cercopithecus pogonias(2n = 72) and Cercopithecus nictitans nictitans(2n = 70), the two species which exhibit the highest diploid numbers among the Cercopithecidae, using G-banding, C-banding, and nucleolar organizing region (NOR)-staining techniques. The karyotypes of these two species show a large number of morphological homologies, but several chromosome pairs cannot be matched. It is suggested that translocations and insertions may have been important in the chromosomal evolution of this group.
