Results are presented that were obtained by analyzing the energy spectrum and anisotropy of E{sub 0} {>=} 10{sup 17} eV primary cosmic rays on the basis of data accumulated at the Yakutsk array for studying extensive air showers over the period between 1974 and 2004. It is shown that spectra corresponding to different regions of the sky differ in shape. Particle fluxes going from the Galaxy and Supergalaxy (a local supercluster of galaxies) disks are enhanced for E{sub 0} {>=} 5 x 10{sup 18} eV and are reduced for E{sub 0} {<=} (2-3) x 10{sup 18} eV. This observation is interpreted as a manifestation of the possible interaction between extragalactic primary cosmic rays and matter of the above structures of space.
