The three-dimensional distribution of galaxies in the region of the Pisces-Perseus supercluster can be reconstructed by using redshifts to indicate distance. Over 2700 galaxies in the region between RA 22 h and 4 h and from the equator to declination + 50 deg now have measured redshifts. The canonical Pisces-Perseus supercluster ridge, lying at a redshift of between 4000 and 65000 km/s, dominates the region north of declination + 30 deg. In the southern region, a number of narrow structures appear to connect the Pisces-Perseus supercluster with the Local Supercluster. The distribution is confined to intersecting sheets and filaments; a major portion of the foreground between the Local Supercluster and Pisces-Perseus is empty.
