We present and discuss the latest addition of the Montreal Blue Galaxy (MBG)survey. Inspection of 59 Curtis Schmidt plates resulted in the identificationof 135 new UV-bright galaxies with B < 15.5. This brings the total number ofMBGs to 469. New results of the $V/V_m$ test show that our survey is completeto B = 14.7.  From our most recent spectroscopic follow-up, we confirm the discovery of onenew Seyfert 1 galaxy and possibly one new Seyfert 2 galaxy. We confirm also thebias of the MBG survey towards the low-excitation and metal rich StarburstNucleus Galaxies (SBNGs). The spectral characteristics of the MBGs are similarto those of the infrared luminous IRAS galaxies. As a common characteristic,they show a mean ratio Log([NII]/H$\alpha$) in excess of 0.2 dex as compared tonormal disk HII regions. In general, the MBGs have lower far-infraredluminosities ($L_{IR} < 10^{11} L_{\odot}$) and are nearer (z < 0.05) than theluminous IRAS galaxies.  The distribution of the morphologies of the MBGs indicates a high number ofearly-type spirals (Sb and earlier). Nearly half of these galaxies also possessa bar. In our sample, the fraction of galaxies with bars depends on themorphology and increases towards the late-type spirals. However, if we consideronly isolated galaxies, the late-type spirals show a clear tendency to bebarred. Signs of a recent interaction with neighbor galaxies are obvious onlyin 24% of our candidates. Although this number is only a lower limit, it isnevertheless sufficiently low to suggest that in a majority of massive galaxiesthe burst of star formation do not depends solely on dynamical processes.Comment: 24 pages, 6 Latex tables and 6 Postscript figures, uses aasms4.sty,  accepted for publication in the Astronomical journa
