Abstract

Forty-two chromosomes were counted from expanded cultured cells of four Celebes apes, Cynopithecus niger. Mitotic cells from three Indian langurs, Presbytis entellus, contained 44 chromosomes. These counts support cytogenetically the taxonomical classification of these animals according to Simpson.
