a second set. Further, in none of the Edenzates are there any 
central incisor teeth, and in all but one there are no incisors at 
all. In two genera only are there no teeth; so that the name 
Edentata is not a very appropriate one. In all, the toes are fur- 
nished with long and powerful claws. 
The Edentata admit of division into two sections, according 
as they live upon a vegetable diet and live in trees, or are 
carnivorous and live upon or below the ground. In the first 
section are only the Sloths (Bradypodide), which are exclusively 
confined to South America, inhabiting the vast primeval forests 
of this continent, They are in every way adapted for an arbo- 
real life, and are “ destined to be produced, to live, and to die

ground ; but the feet are furnished with extremely long curved

Armadilloes (Dasypodide) are also exclusively confined to South 
America ; but they are carnivorous, burrowing animals, and are 
furnished with strong digging-claws. The upper surface of the 
body is covered with a kind of armour, formed of hard bony 
plates or shields, which are united at their edges. Most of them 
can roll themselves up into a ball, and they can all bury them- 
selves in the ground when pursued. 
The remaining South American Edentates are the hairy
