In this paper, we obtain some new Razumikhin type theorems of stability andboundedness for functional differential equations with infinite delay. Under thecondition of V((ξ)) V(t), we substitute the requirement satisfying V 0 insome sets of points {(t, x)|V(t, x) = αi or βi, i = 1, 2,...} for the requirementV 0 in classical theorems of stability and boundedness (for reference, see[1]-[3]).
