Order II. Edentata. Edentates. 
The Order EpENTATA contains certain mammals of an inferior 
organization, and with various forms of body covering beside that 
of hair. The designation, Toothless, is not altogether correct as 
applied to the various species, for, while some, like the Anteaters and 
Pangolins, are destitute of teeth, others, as the Sloths, Armadillos, 
etc., are provided with them, although the incisors are wanting in 
all. The Sloths, so-called on account of their slow movement, have 
a thick covering of coarse, bristly hair, and the fingers and toes of 
the different species are armed with long prehensile claws, by means 
of which the animals maintain their position suspended from the 
limbs of trees. While the color of the Sloth’s coat is generally some 
shade of gray, it is not infrequently tinged with green caused by a 
growth upon the hair of an algous plant whose vitality is stimulated 
by the dampness of the forest in which the animals dwell, and is a 
means of harmonizing them with the leaves and so affording conceal- 
ment from all enemies, as creatures without recognizable form, 
suspended amid the branches. Although very helpless when upon 
the ground, Sloths make an attempt to defend themselves by trying 
to seize and strangle their enemies, and sometimes they succeed in 
doing this, or inflict serious wounds with their sharp, hook-like claws. 
Their food is composed of leaves, buds, and young shoots of various 
trees, some species exhibiting a desire for certain kinds only. Among 
the branches the Sloths frequently move with considerable rapidity, 
but on the ground their progress is slow and performed with difficulty. 
These animals rarely emit any sound, but on provocation will make 
a curious grunting noise, or at other times disturb the stillness of the 
forest by a:long-drawn, shrill, wail-like cry, expressive of the loneli- 
ness of their monotonous life.
