We have measured resistivity, magnetization and magnetoresistance in polycrystalline La0.7\_xPr, Sr0,3Mn0s with fixed carrier concentration. With decreasing the average ionic radius of the La site ( rA), we found a decrease in T,, an increase in resistivity at T,, and an increase in the magnitude of
