This paper is concerned with the main features of the far UV spectrum of the binary star AX Mon, observed with the IUE satellite at phase 0.568. Ions indicating a large range of ionization stages, going from C I, O I, N I to S IV, C IV, N V, are present. The spectrum is dominated by shell absorption lines of Fe II, Fe III, Si II, S II, C II, Al II, Al III, Mg II, and Ni II. Two satellite components are clearly indicated in all these lines except for Ni II which presents only one. Their mean velocities are + 10 + or - 5 km/s, - 75 + or - 10 km/s, and - 260 + or - 15 km/s. Red emission wings are observed in the Mg II resonant doublet at 2800 A, which shows a P Cygni profile. Each of the absorption lines of the Mg II doublet is formed by a narrow component, which is blended with the Mg II interstellar line and a broad component, which shows a complex structure. Broad and asymmetrical profiles are observed for the Si IV, C IV, and N v resonance lines with blue edge velocities about - 700 + or - 30 km/s.
