Ion-acoustic solitary waves in a warm, magnetoplasma under the initial drift motion of the electrons in the direction of the magnetic field, have been investigated. It has been established that both compressive and rarefactive solitons exist within the parametric domains. For higher (lower) values of the electron drift velocity [ital v][sub [ital e]][sup [prime]], it is demonstrated that the solitary wave is always subsonic (supersonic) near the lower regime of [alpha] (=[ital T][sub [ital i]]/[ital T][sub [ital e]], the ion to electron temperature ratio) and upper regime of [alpha], respectively. It is of paramount importance to report that a higher and constant amplitude soliton region corresponding to low ion temperature and Mach number [ital M] exists for the upper ranged values of [ital v][sub [ital e]][sup [prime]] but to the contrary a smaller and constant amplitude soliton region exists corresponding to high ion temperature for the lower ranged values of [ital v][sub [ital e]][sup [prime]].
