Class II. Flagellata (Mastigophora). In many Rhizopoda (p. 172) the pseudopodia disappear at the time of reproduction and are replaced by one or two tlagella; others have, be- sides pseudopodia, permanent flagella. Such flagellate spores and flagel- late Rhizopods form the transition to the Mastigophora, which are per- manently flagellate, the flagella serving as organs of locomotion and feeding. The three orders must be described separately. Order I. Autoflagellata. The Autoflagellata form a polymorphic group. The free forms are usually oval, mth a nucleus in one end.
