N2 - Transport properties of (Formula presented) in the overdoped region have been investigated in detail. In a narrow region around (Formula presented) in (Formula presented) we have found anomalously less-metallic behaviors of the electrical resistivity and the thermoelectric power than usual. The value of x around which the anomalies occur decreases through the substitution of Zn; namely, with increasing y. In the anomalously less-metallic samples, superconductivity has been found to be a little suppressed. These anomalies are not connected with the structural phase transition between the tetragonal high-temperature phase (Formula presented) and the orthorhombic midtemperature one (Formula presented) There is a possibility that an ordering of holes and/or spins is formed or fluctuates in the samples exhibiting the anomalous properties in the overdoped region.
