The following list is a record of the species of Mastigophora and 

 Infusoria identified in material taken from the fresh waters of Japan. 

 Flagellates and ciliates are very abundant in that country, as 

 elsewhere, and the small number of species here listed indicates 

 brevity of observation rather than any dearth in protozoan fauna. 

 The remarkable thing to be noticed is the identity of the Japanese 

 forms with our common American species.
