The anisotropy in the orientations of the galaxies of the Uppsala (Northern Hemisphere) and ESO/Uppsala (Southern Hemisphere) catalogs is investigated. It is shown that the galaxies of both catalogs exhibit an identical, statistically significant and clearly expressed anisotropy in the orientations of the apparent major axes. The effect is differentiated with respect to the magnitudes, angular diameters, and morphological types. Arguments for its being real are advanced. In the spatial respect, a model in which the normals of the galaxies are coplanar with one and the same plane in space but are oriented randomly in the other directions is preferred. The effect relates either to the outer regions of the Local Supercluster or has an even larger scale.
