The Spider Monkeys are remarkable for the length of their limbs, 

 which causes them to be extremely awkward on the ground, and it 

 is questionable, if in the wild state they often leave the trees upon 

 which they live. The tail is prehensile and is a most valuable adjunct 

 in their movements, serving as an extra hand, for it grasps as firmly 

 as that member can any object within reach. Being long and very 

 flexible, it is often employed to bring branches within reach of the 

 hands, and it can easily sustain the entire weight of the animal. 

 There is quite a number of species, very variable in coloring, distrib- 

 uted from eastern Mexico to southern South America.
