A fourth type of combination, membranula?, combines several of the features of flagella. Thus the powerful motile organs of Didiniviii are composed of a few flagella-like, long cilia, while rhizoplasts run from their basal bodies to the vicinity of the nucleus (Fig. 161, 8). Undulating membranes are limited regionally, to the gullet, margin of the mouth or to a circumscribed area called the peristome. Membranelles are grouped usually, in a curved row the "adoral zone" around the margin of the peristome, but a dorsal ring of membranelles is present in some parasitic forms {c. g., Diplodiniun/, P'ig. 2, p. 20). Cirri are combinations of cilia of usually, the ventral 24.
