摘　　要：中国科学院昆明动物研究所灵长类学联合实验室中国实验动物云南灵长类中心灵长类学联合实验室Based on 11 anatomic specimens, including 7 for Francois' leaf monkeys Presbytis f. francoisi (2 males and 5 females), P. f. leucocephalus (I female, and 3 for Phayre's leaf monkeys P. phayrei (3 females), musculature of the upper and lower limbs of two leaf monkeys were studied and compared with those in other primates. The results showed: in regard to most myological characteristics two leaf monkeys share plesiomorphous ones with Cercopithe-coidea, and some of them are similar to that of the anthropoids. However, there also exist some differences compared with the monkeys.The shared features in two leaf monkeys are as follows:1. There is a thin lacertus f-ibrosus,2. In most specimens of two leaf monkeys exist mm. coracobrachialis me-dialis and profundus, but the latter is absent in one specimen of the Ph-ayre's leaf monkeys.3. M. brachialis is supplied by n. medianus and n. musculocutaneus. But the muscle can not be divided as two separated parts.4. M. pronator teres has only one head, the deep one is absent.5. There exist not the origin on the ulna and radius for m. flexor digitorum superficialis.6. The tendons of the m. flexor digitorum profundus for the thumb derive entirely from radial part of this muscle, which is similar to that of the anthropoids.7. The origin of them, brachioradialis extends up to the mid-upper third of the humerus, or even more.8. M. extensor digiti quinti proprius give rise to the tendons to the fourth and fifth fingers.9. No m. extensor pollicis brevis is present. But a small tendonal bundle connecting tendon of m. extensor pollicis longus, derives from the inscr-tional tendons of the m. abductor pollicis longus for the first metacarpal bone in two specimens of the Francois' and Phayre's leaf monkeys. This might represent the m. extensor pollicis brevis.10. The tendons of the m. extensor digiti secundi proprius go to the Ⅰ and Ⅱ fingers.11. Only one head, the superficial one, of the m. flexor pollicis brevis exists.12. The head of m. adductor pollicis can not be differentiated in
