The data for superconducting PrBa{sub 2}Cu{sub 3}O{sub 7} and Pr{sub 2{minus}xCe{sub x}Sr{sub 2}NbO{sub 10}}indicate that the superconductivity of these compounds is normally unaffected by rare-earth-site Pr but is quenched by a Pr{sub Ba} or Pr{sub Sr} defect on the other side of an adjacent cuprate-plane. Hence the primary superconducting condensate must reside not in the cuprate planes, but in the charge-reservoir regions containing hypocharged oxygen, namely in the BaO layers or the CuO chain layers of PrBa{sub 2}Cu{sub 3}O{sub 7}, and in the SrO layers of Pr{sub 2{minus}x}Ce{sub x}Sr{sub 2}Cu{sub 2}NbO{sub 10}.
