ANIMAL ACTIVITIES. 
CHAPTER I. 
ANIMALS CLASSIFIED. 
IN the course of these lessons on Animal Activities 
the student will be called on to observe many forms of 
animal life and to learn many new and perhaps strange 
names. In order that he may keep his bearings and 
feel somewhat at home from the start, the following 
classification of the animal kingdom is given. The 
student should read over this table carefully, noting 
especially the meaning of the names in the light of 
their derivation, and he should refer to it frequently. 
Later in the book more will be said about classification. 
The animal kingdom is divided by zoologists into 
subkingdoms. As these subkingdoms are supposed 
to consist of animals related through their ancestry, 
they are sometimes called phyla ( phylum , a tribe). 
Since Zoology is a rapidly growing science, authorities 
differ in regard to tne number of divisions, or phyla, 
and also in regard to the names for some of the 
divisions.
