Abstract
The testicular histology of the dusky leaf monkey, Presbytis obscura,is described following a study of material from 16 adult males collected over a 13-month period in Peninsular Malaysia. The histological appearances were similar to those of the other cercopithecines studied so far. No seasonal variation in the height of the seminiferous epithelium was observed, and spermatogenesis was seen in all the adult testes. These findings suggest that males of this species are capable of breeding throughout the year. These results are discussed in relation to field observations of births of this species and to the birth patterns exhibited by other species of langur.
