Query: New Wolf-Rayet Galaxies with Detection of WC Stars   We report the discovery of two new Wolf-Rayet (WR) galaxies: Mrk~1039, and
F08208$+$2816. Two broad WR bumps at 5808\AA~ and 4650\AA~ indicate the
presence of WCE and WNL star population in all two sources. We also confirm the
presenceof WR features in Mrk~35, previously detected in a different position.
The observed equivalent width of the WR bump at 4650\AA~ and the derived number
ratios of WR/(WR$+$O) imply that star formation in these sources takes place
inshort burst duration. Comparisons with the recent models of WR populations in
young starbursts with the observed EW(\HeII)/EW(\CIV)/EW(WRbump) and their
relative intensitie provide an indication that the stellar initial mass
function in some WR galaxies might not be Salpeter-like. It is interesting to
find that the luminous IRAS source, F08208$+$2816, has little dust reddening,
probably because of the existence of a powerful superwind. By comparisons with
other starbursts observed with the Hopkins Ultraviolet Telescope, F08208$+$2816
as a merging system renders a chance to study the contribution from young
starbursts to the UV background radiation in universe.
