IUE spectra of the white dwarf component of HD 149499, discovered from
the Skylab experiments S-019 UV survey, show prominent lines of He II.
The star appears to be helium-rich with He/H not less than 1. The
ultraviolet fluxes show the temperature to be within the range
70,000-100,000 K, with the most probable value near 85,000 K.
