Postal 70-264,04510 Mexico D. F., Mexico Received 1995 November 14; revised 1996 December 18 ABSTRACT We present and discuss the latest addition of the Montreal Blue Galaxy (MBG) survey. Inspection of 59 Curtis Schmidt plates resulted in the identification of 135 new UV-bright galaxies with B < 15.5. This brings the total number of MBGs to 469. New results of the V/V_m_ test show that our survey is complete to B = 14.7. From our most recent spectroscopic follow-up, we confirm the discovery of one new Seyfert 1 galaxy and possibly one new Seyfert 2 galaxy. We confirm also the bias of the MBG survey towards the low-excitation and metal rich Starburst Nucleus Galaxies (SBNGs). The spectral characteristics of the MBGs are similar to those of the infrared luminous IRAS galaxies. As a common characteristic, they show a mean ratio log([N II]/H{alpha}) in excess of 0.2 dex as compared to normal disk H II regions. In general, the MBGs have lower far-infrared luminosities (L_IR_ < 10^11^ L_sun_) and are nearer (z < 0.05) than the luminous IRAS galaxies. The distribution of the morphologies of the MBGs indicates a high number of early-type spirals (Sb and earlier). Nearly half of these galaxies also possess a bar. In our sample, the fraction of galaxies with bars depends on the morphology and increases towards the late-type spirals. However, if we consider only isolated galaxies, the late-type spirals show a clear tendency to be barred. Signs of a recent interaction with neighbor galaxies are obvious only in 24% of our candidates. Although this number is only a lower limit, it is nevertheless sufficiently low to suggest that in a majority of massive galaxies the burst of star formation does not depend solely on dynamical processes.
