C. 224. Part of the left hind-limb of a Dog (Canix familiaris). 

 The tendon of the plantaris passes in a seraispiral round 

 the inner side of that of the gastrocnemius ; it is not 

 wholly attached to the calcaneum but passes over its 

 surface and is continued into the flexor brevis digitorum. 



O 



A small pronator tibiae is present. 0. C. 64 z q c.

C. 225. The superficial muscles of the right hind-limb of a 

 Lemur (Lemur mongoz). In this arboreal animal the 

 extensor muscles are decidedly feeble ; the flexors of the 

 knee, on the other hand, have considerable power, mainly 

 owing to their insertion at some distance below that joint. 

 The sartorius, gracilis, and semitendinosus unite near their 

 distal extremities and are inserted by a common tendon. 

 The biceps rises from the proximal part of the anterior 

 border of the semitendinosus. The prse-semimembranosus, 

 as in other Lemurs, is absent. The tibialis anticus is 

 inserted by two tendons. The flexor brevis digitorum 

 rises by two separate heads : 1, from the plantar fascia; 

 2, from the deep flexor tendons, this latter part may include 

 the accessorius. 0. C. 64 M bh.

C. 226. Distal portion of the left hind-limb of a Lemur (Lemur 

 mongoz), showing several of the deep muscles. A pronator 

 tibiae is present between the heads of the tibia and fibula. 

 Its fibres pass slightly downwards from the fibula. A 

 corresponding muscle is situated between the distal ends of 

 the same bones. The two outermost short extensors 

 (peroneus quarti dig. et quinti dig.) rise from the fibula, 

 those belonging to the inner three toes from the dorsum of 

 the foot as usual. A blue rod has been placed beneath the 

 second part of the flexor brevis (see preceding specimen), 

 and a green rod under the lumbricals. 0. C. 64 M bg.
