A redshift distribution study of a sample of 283 bright galaxies in an 1800 square degree area in the Linx-Gemini region, including new redshifts for 59 galaxies, provides evidence for the existence of several large scale structures. The Linx-Ursa supercluster with mean velocity of 3500 km/s, a large cloud of galaxies extending for at least 50/h Mpc around Abell 569, a low density filament in Gemini composed mainly of spirals, and a possible outstanding structure containing the cluster Abell 779, are found. The Abell 569 cloud is suggested as the structure most likely connected with the Perseus supercluster across the galactic dimming region.
