H I-line observations of 65 galaxies at low galactic latitudes northeast of the Perseus supercluster are presented. 27 galaxies have been detected, raising the number of radial velocities known for this area to 45. The detected galaxies are normal in all respects. The new radial velocities present evidence that the Perseus supercluster is extended across at least a part of the galactic zone of avoidance. Taking these data together with data from the literature, the Perseus supercluster can be traced from the cluster Abell 2634 at α = 23h36m, δ = 26°46arcmin to the 3C 129 cluster at α = 4h45m, δ = 45°0arcmin. The ends are probably due to missing data. The author studies the distribution of galaxies in this region in Cartesian coordinates. The study shows that this supercluster is a filamentary object which is plane at the same time. It is bent in this plane but does not have any points of inflection.
