226 THE ARTISTIC ANATOMY OF ANIMALS 



It consists in a duplication of the tendon of the short pero- 

 neal, one of the branches of which goes to the fifth meta- 

 tarsal, and the other to the fifth toe ; it is sometimes a single 

 fasciculus which goes to the phalanges of this latter. We 

 have met with examples of these anomahes.* In the pig, 

 the short peroneal is situated on the same plane as the long. 

 It consists of two clearly distinct fascicuh, which arise from 

 the fibula. The tendon of the anterior fasciculus proceeds 

 to the great external toe — that is to say, the fourth, of 

 which it is the proper extensor. The posterior fasciculus 

 terminates on the small external toe, the fifth, of which it 

 is in like manner the extensor. 



In the ox, the fleshy fibres of the short peroneal arise from 

 a fibrous band which replaces the fibula, and from the ex- 

 ternal tuberosity of the tibia. Situated behind the long 

 peroneal and on the same plane, it terminates in a tendon 

 which appears at the level of the inferior part of the leg ; it 

 passes in front of the canon, and is inserted into the external 

 toe, of which it is the proper extensor. 



In the horse, it is the sole representative of the peroneal 

 muscles, and veterinary anatomists have given it the name 

 of the lateral extensor of the phalanges. 



Its fleshy body arises above from the external lateral 

 ligament of the knee-joint, and from the whole length of the 

 fibula. In the middle third of the leg it is narrowed ; 

 lower down it is replaced by a tendon. This is lodged in 

 a groove hollowed on the external surface of the inferior 

 extremity of the tibia ; then after passing along the external 

 surface of the tarsus, it is directed forward, and proceeds to 

 blend towards the middle of the canon-bone with the ten- 

 don of the long extensor of the toes, or anterior extensor 

 of the phalanges, of which it shares the insertions. It 

 extends the phalanges into which it is inserted. It also 

 flexes the foot.
