THE MUSCLES OF THE LOWER EXTREMITY. 219 



interesting little muscle. It arises fleshy from the antero 

 internal aspect of the head of the tarso-metatarsus, just 

 below its summit ; from the corresponding edge of the 

 shaft below ; and from the tendon of the tibialis anticus. 

 The delicate little bundle of fibres pass down the antero- 

 iuternal edge of the shaft of the bone, which is slightly 

 concaved to receive them, in order that the close-fitting 

 podotheca may not interfere with their proper action ; 

 when just before arriving at the apex of the accessory 

 metatarsal, they unite with a delicate, though strong, 

 little tendon, which, passing round behind that bone 

 and over the hallucial basal joint, runs along over the 

 top of the phalanx of the hallux close to the bone, 

 to be finally inserted into the process at the superior 

 base of its bony claw. 



Professor Owen, in the second volume of his Anatomy of 

 Vertebrates, describes also an extensor brevis digitorum ; 

 but that muscle does not occur in the Eaven, and the 



received a similar designation at the bands of others. Gadow has 

 bestowed the same name upon it, and furnished the following 

 synonymy :
