THE AMERICAN NATURALIST [Vol. LV 



Whether these widely distributed marine protozoa 

 which in some cases are able to live in fresh water may 

 not be fonnd in all parts of the world remains to be 

 found out; with attention turned to their discovery, it 

 may be hoped that knowledge of both the life histories 

 and the taxonomy may soon be placed upon a firmer basis.
