We have carried out a survey of the photometric (V) variability of 61 "known" or suspected small-amplitude red variables, mostly M giants. Approximately two-thirds appear to be variable; several suspected variable comparison stars have also been identified. The incidence and average amplitude of variability increase rapidly from spectral type M0 III to M6 III.
