THE RABBIT. 363 



a strong tendon from the outer condyle of the femur, passes 

 backwards beneath the external lateral ligament (§ 474), and 

 curves round the posterior surface of the proximal end of 

 the tibia to be inserted into the pre-axial edge of that 

 surface : divide and reflect. 



464. The flexor digitorum communis {fl.d.c), closely 

 applied to the posterior surface of the tibia : it arises from 

 the outer tuberosity of the tibia and from the head of the 

 fibula : its tendon enters the foot to the inner or pre-axial 

 side of the calcaneum, then expands and divides into two, 

 each subdivision soon dividing again : the four slips thus 

 formed have the same relation to the digits as those of the 

 flexor profundus to the digits of the manus (§ 427). 



465. The lumbricales {lb), three very small spindle-shaped muscles 

 arising from the tendon of the preceding, and inserted on the pre-axial 

 sides of the proximal ends of the proximal phalanges of the third, fourth, 

 and fifth digits respectively. 



466. The peroneus longus {pr.l), a long, slender 

 muscle arising from the outer tuberosity of the tibia : it 

 passes into a long tendon which traverses a groove on the 

 post-axial side of the distal end of the tibia, and is inserted 

 into the cuboid : divide and reflect. 



467. The peroneus brevis {pr.b), arises from the outer 

 tuberosity of the tibia, partly united with the peroneus quarti 

 digiti ; its tendon accompanies that oi ±he peroneus longus, 

 and is inserted into the proximal end of the fifth (last) 

 metatarsal. 



468. The peroneus quarti digiti {pr.d.^), arises from 

 the shaft of the fibula, being united at its origin with the 

 preceding : its tendon enters the foot with those of the 

 other peronei, and is inserted into the distal end of the fourth 

 (apparent third) metatarsal. 



469. The peroneus quinti digiti (pr.d.s), arises from
