The amoeba belongs in the class of protozoans called 

 RJiizopoda " root footed." 



Other classes of Protozoans are the hifusorians (in the 

 broad sense of the term), which have many waving cilia 

 (Fig. 17) or one whip-like flagellum (Fig. 18), and the 

 Foraminifers , which possess a calcareous shell pierced with 

 holes (Fig. 19). Much chalky limestone has been formed 

 of their shells. To which class does the paramecium

Protozoans furnish a large amount of food to the higher 

 animals.
