CLASSIFICATION OF ANIMALS. 
303 
remaining classes of animals, without going into so minute a de- 
tail of their orders. 
Class ii, Contains Birds, (.Tees,) which are distinguished 
by having the body covered with feathers and down, long naked 
jaws, two wings formed for flight, and bi-ped (from bis two, and 
pedes feet.) The orders in this class, are chiefly distinguished 
from each other by the peculiar make of the bill and feel. 
Class mi, Amphibia , contains amphibious animals, including 
what are commonly called reptiles. It is divided into four or- 
ders : 
1st. With shells over their back, and four feet ; as the tortoise 
and turtle. 
2d. Covered with scales, and having four feet ; as the croco- 
dile and lizard. 
3d. Body naked, destitute of feet ; as serpents and snakes. 
4th. The body naked, and having two, or four feet ; as the 
frog and toad. 
Class iv. Contains Fishes, (Pisces,) natives of the water, 
unable to exist for any length of time out of it; swift in their 
motions, and voracious in their appetites; breathing by means 
of gills, which are generally united in a long arch ; swimming 
by means of radiate fins, and mostly covered with scales. 
Second Grand Division. 
Class v. Mollusca, bodies soft, without bones, but their mus- 
cles attached to a skin which forms a calcareous covering called 
a shell, and is in many cases, produced from their skin. These 
animals possess no organs of sense but those of taste and sight, 
and these are often wanting ; the nautilus and cuttle fish are of 
the highest order of Molluscous animals. 
One order contains animals without heads, having a shell usu- 
ally of two pieces; these are called bivalves ; as the oyster, 
clam, and snail. 
Third Grand Division. 
We proceed next to those animals called Articulated ; these 
have jointed trunks, and mostly jointed limbs. They possess the 
faculties of changing place, (locomotion ;) some have feet and 
others are destitute of them, moving by trailing along their 
bodies. 
Class vi. Annelida, contains such animals as have red blood, 
without a bony skeleton ; bodies soft and long, covering divided 
into tranverse rings, living mostly in water ; some of them se- 
crete calcareous matter which forms a hard covering, or shell ; 
as the earth, or angle worm, and leech. 
Second division containing- one class — Third division containing four 
classes.
