HIND-LIMB. 159 



portion of the flexor brevis provides tendons for II. & 

 III., while IV. & V. are supplied by the portion that rises 

 from the plantar tendons. The accessorius though present 

 is weak. Only two lumbricals are shown. 0. C. 64 N. 



C. 341. Superficial muscles of the right hind-limb of a Chim- 

 panzee (AnthropopitJiecus troglodytes^). There is a distinct 

 though small tensor fasciae latae. The gluteus maximus 

 and femoro-coccygeus are closely united. The ischial and 

 femoral heads of the biceps cruris do not unite before their 

 insertion. The semitendinosus shows a delicate tendinous 

 intersection in the middle of its length. A separate prae- 

 semimembranosus is present. The tibialis anticus is double 

 for some distance above the annular ligament. A fine 

 tendon, probably representing the extensor brevis V., 

 separates off from the peroneus brevis and runs along the 

 dorsum of v. to the phalanges.

C. 242. Nerves and deep muscles of the left hind-limb of a 

 Chimpanzee (Anthropopithecus troglodytes). A plantaris 

 is present. Presented ly John Marshall, Esq. 



C. 243. The left deep flexor tendons with the flexor brevis 

 digitoruni and lumbrical muscles of a Chimpanzee (Anthro- 

 popithecus troglodytes). The flexor tibialis (flex. long, 

 digitorum) supplies a tendon to V. and the greater part of 

 that to ii. The flexor fibularis (flex. long, hallucis) sends 

 tendons to I., Hi., iv., and strengthens that to II. The 

 flexor brevis has origins from both calcaneum and the 

 tendons of flex, tibialis, the former supplies n. & m., 

 the latter iv. & v. The tendon to n. is also enforced 

 by a large muscular slip from the flexor tibialis tendon. 



C. 244. A vertical section of the Human tibia and patella, and of 

 the tendon of the extensors of the leg, showing the distance 

 to which the tendon is removed from the centre of motion 

 by the interposition of the la(ter bone. 0. C. 277.
