  In a diagram of metallicity (\~z) vs. luminosity (M$_B$), the different types
of nearby (Z $< 0.05$) starburst galaxies seem to follow the same linear
relationship as the normal spiral and irregular galaxies. However, for
comparable luminosities the more massive starburst nucleus galaxies (SBNGs)
show a slight metallic defficiency as compared to the giant spiral galaxies.
Furthermore, the SBNGs do not seem to follow the same relationship between \~z
and Hubble type (T) than the normal galaxies. The early-type SBNGs are metal
poor as compared to normal galaxies. It may suggests that the chemical
evolution of a majority of the nearby starbursts galaxies is not completely
over and that the present burst represent an important phase of this process.
