We present 167 new redshifts of galaxies in the region around Abell 262, NGC 383, and NGC 507, which is situated within the filamentary main ridge of the Perseus-Pisces Supercluster. We investigate the dynamics of galaxies in this region by examining their distribution in spatial and velocity space. Clusters in the ridge appear to have substructure: the N507 group has a very small-scale substructure near its central core, and the N383 group shows the strongest evidence for substructures; it is basically composed of a few compact groups. Clusters in this region are perhaps still in an early evolutionary stage, accreting neighboring smaller groups and galaxies in the supercluster.
