 no teeth ; so that the name Edentata is not a very ap])i'opriate one. 

 In all, the toes are furnished with long and powerful claws. 



The order Edentata is conveniently divided into two great sec- 

 tions, in accordance with the nature of the food, the one section 

 being herbivorous, the other insectivorous. In the former section 

 is the sing'e group of the Sloths (Bradypodidce). In the latter are 

 the two groups of the Armadillos (Dasypodidie) and the vaiioiis 

 ■ species of Ant-eaters. 



The Sloths {Driidypodidte) are exclusively confined to South 

 America, inhabiting the vast primeval forests of this continent.

 awkward when npon the ground ; but the feet are furnished with 

 extremely long curved claws, so that the animal is enaliled to move 

 about freely suspended back dowuAvards fi-um the branches of the 

 trees. 



The second family of the Edentata is that of tlie Dasypodidce or 



Armadillos. These are also found exclusively in South America, 



but they are very different in their habits. The Armadillos (fig. 



231) are burrowing animals, furnished with strong digging-claws
