The existence of two branches of moving anharmonic localized modes is shown fora one-dimensional (10) lattice w'ith hard quartic anharmonicity. By tlte use of a pairof exactly solvable model nonlinear lattice equations as a reference system, approx-imate analytical expressions for envelope functions, the eigenfrequencies and thevelocities of low- and high-frequently modes are obtained for eacla of envelope-kinklike modes and envelope-solitonlilce modes. Tlte approximate axxalytical resultsare tested by numerical experiments to e;how that these two branches of the modes arerobust against generation at initial stages of ripples, eventually preserving their ownprofiles as time evolves.
