Standard models for deep galaxy counts are based on luminosity functions (LF) with relatively flat faint end (\alpha\sim-1.0). Galaxy counts in the B--band exceed the prediction of such models by a factor of 2 to more than 5, forcing the introduction of strong luminosity and/or density evolution. Recently Marzke et al. (1994a) using the CfA redshift survey sample find that the number of galaxies in the range -16
