initials. 



This muscle presented a distinctly cleft condition and is in all 

 probability the homologue of the extensor ossis inetcarpi pollicis and 

 the extensor brevis pollicis. It had two tendons and two bellies 

 which could be separated nearly as far as the tubercle of the tibia. 

 A few fibres run from one to the other near the point where the 

 bellies become tendinous. The one tendon is inserted into the ecto- 

 cuneiform, while the other or lower tendon passes to the inner side of 

 the head of first metatarsal. 



Extensor proprius kallucis. 



The tendon of this muscle in its course to the last phalanx is 

 intimately bound down to the dorsum of the first metatarsal, thus 

 acting as an abductor of the great toe. 



Extensor loncjus dic/itorum. 



As in man. Intertendinous bands were present over the dorsum 

 of the foot. 



Peroneus tertius. 



There was no trace of this muscle. 



Extensor brevis diyitorum. 



This was a well-developed muscle situated in the usual position. 

 It possessed four tendons for the four inner digits. That supplying 

 the great toe had to take a transverse course across the dorsum of the 

 foot to gain its insertion and thus looked almost like a separate muscle. 



Peroneus lonyus. 



The insertion of this muscle was confined to the base of the first 

 metatarsal bone and did not, as in man, send slips to the internal 

 cuneiform and base of second metatarsal bone. Huge considers that 

 the peroneus longus reaches its most specialised condition in the 

 anthropoids and that in man it shows a tendency to reversion.
