Figure 2 



Three interesting types of flagellated organisms are here shown. There is, 

 first, the colonial form, Vohox, which appears under the microscope as a 

 greenish-colored sphere, slowly revolving by action of thousands of flagella. 

 Usually, as shown, immature asexual colonies, also in action, are to be seen 

 through the wall of the parent colony. The two unicellular Flagellates are 

 Eugkna and a closely related type, Peranema (lower left), which lacks chlo- 

 rophyll. In most cases the flagella are shown. Actually, however, owing to 

 their rapid vibration, they would not be seen in living cells.
