Abstract: The golden monkey (Rhinopithecus roxellanae) is rare in number and little is known about its sexual behaviour. The present paper deals with its characteristics of sexual activities. The examined animals included two adult male and four females which were housed at Beijing Zoo and observed from August to September, 1986.Either the male or the female may be initiator of sexual activities. The female initiates sexual behaviour by displaying the following gestures: She lies on the belly, fully flexing her limbs under it, and the back is level, while her head turning to the side, looking at the male with the tail falling on the ground,The male initiates sexual behaviour by chasing. Throughout copulation his tail forms itself into a circle.After copulation the male is groomed, sitting or lying.In golden monkey, the sexual skin of perineum region of both sex may change into light blue, their callosities being light red but perineum swelling will not occur.The sexual behaviour for the golden monkey is different from that observed in Indian langur monkey (Presbytis entellus) .
