Order 1. Britta or Edentata, — These creatures, repre- 
sented by the sloths, ant-eaters, pangolins, and armadillos, 
stand next above the marsupials, as the 
brain is but little better developed than 
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 
are adapted for grasping or digging, 
and end in large straight or curved 
claws. The body is either hairy or 
protected, as in the pangolins and ar- 
madillos, with large thick scales. They 
feed on insects and decayed animal 
They are of mod- 
erate size, though certain extinct forms 
were colossal in stature. 
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
