The weights of the several muscles in the Macacus Nemes- 

 trinus were found to be — 



1. Flexor hallucis longus, . . . 0.66 oz. av. 



2. Flexor digitorum longus, . . 0.36 ,, 



3. Accessorius, 0.05 „ 



(d.) Monkeys of the New Continent The Capuchin and 



Negro monkeys of South America 

 exhibit, in the arrangement of the 

 flexor tendons of the foot, a type 

 quite different from that of the 

 monkeys of the Old World. This 

 arrangement is shown in Fig. 8, 

 which represents the tendons of 

 the foot of Lagothrix Humboldtii, 

 or Negro monkey of South Ame- 

 rica. 



In the monkeys of the New 

 World, the flexor hallucis longus 

 supplies part of the first toe, and 

 the whole of the long flexors of 

 the second, third, and fourth toes ; 

 while the flexor digitorum longus supplies the remainder of 

 the flexor tendon of the first toe, and the whole long flexoi 

 tendon of the fifth toe.
