Photometry is presented for spiral galaxies in five clusters of galaxies in the direction of the Perseus-Pisces supercluster. The 21 cm observations of these galaxies by Giovanelli et al. (1982, 1986) are employed to measure distances of these clusters by means of the Tully-Fisher relation. Most of these are in fact more distant than the supercluster and have peculiar velocities averaging 400 km/s. This is broadly in agreement with the earlier result of Willick (1990, 1991) who analyzed a large field sample. A local model in which galaxies are infalling to two mass concentrations, one in Perseus-Pisces and one in Hydra-Centaurus, fits the data at least as well as bulk flow. The present data leave both these possibilities open.
