Scientific paper

Spectral scans are presented of two galaxies, NGC 6764 and Mrk 309, which show the Wolf-Rayet emission band 4650 A in the spectra of their nuclei. Their spectra are discussed and compared with the spectra of two previously known dwarf galaxies which show this same feature, as well as with the spectrum of the H II region NGC 604 in M33. The numbers of Wolf-Rayet stars in the nuclei of NGC 6764 and Mrk 309 similar to those in the Galaxy, or of supermassive Wolf-Rayet stars similar to the one which may be present in Dor, are estimated.
