Photometry is presented for spiral galaxies in five clusters of galaxies in the direction of the Perseus-Pisces supercluster. We employ the 21 cm observations of these galaxies by Giovanelli, Haynes, and colleagues 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^-1^. This is broadly in agreement with the earlier result of Willick who analyzed a large field sample. Examination of the behavior of the whole sample of 21 clusters with Tully-Fisher distances within 10⁴^ km s^-1^ is suggestive of the bulk flow kinematic model originally fitted to elliptical galaxies in this volume by the Seven Samurai. However, 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.
