is therefore necessary that the muscles of the chest

 very much greater extent, in birds as every one who has

 inches long. It is found in the forests of Surinam and 

 Brazil, and has very powerful claws. It is accused of

it lives principally on white ants and other insects. It 

 has no less than from twelve to thirteen movable bands 

 interposed between its anterior and posterior body-shields. 

 Another kind known as the apar has but three movable 

 bands, but it can roll itself up very perfectly. Darwin 

 tells us : 



" It has the power of rolling itself up into a perfect 

 sphere, like one kind of English woodlouse. In this 

 state it is safe from the attack of dogs, for the dog not 

 being able to take the whole in its mouth, tries to bite 

 one side, and the ball slips away. The smooth, hard 

 covering offers a better defence than the sharp spines of 

 the hedgehog."
