Order 1. Bruta or Edentata. — These creatures, repre- 

 sented by the sloths, ant-eaters, pangolins, and armadillos, 



stand next above the marsupials, as the

 \,.y^m in the latter animals. The teeth may 

 be absent, as in the common ant-eater, 

 but when present they are not encased 

 in enamel. Usually there are no incisor 

 teeth, but those on the sides of the jaw 

 may exist in the armadillo. The feet

The leaf-eating forms, viz., the sloths, differ from the 

 other Bruta in the very long and slender limbs, the hinder 

 pair the shorter. There are five teeth above and four 

 below, which become sharp with use, like chisels; the stom- 

 ach is said to be remarkably complex. In disposition these 

 creatures are types of sluggishness; they live in trees, being
