Low and high resolution ultraviolet spectra of the hydrogen-deficient star HD144941 were obtained using IUE. The energy distribution was compared with model atmospheres and found to be consistent with the effective temperature determined from the ionization equilibrium, but a UV excess is present below 1600A. A departure from the normal Galactic reddening law provides the most likely explanation. Absorption lines formed in an expanding envelope were modelled in the comoving frame. These yield a mass-loss rate in the range -1.1 to the minus 9th power less than M/solar mass/yr less than -2.1 to the minus 10th power. This normal mass-loss rate fails to account for the observed hydrogen-deficiency.
