  Optical spectroscopy of 76 galaxies, 48 of which are projected in the
direction of the Virgo cluster and 28 onto the Coma-A1367 supercluster, is
reported. Adding these new measurements to those found in the literature, the
redshift completeness in the Virgo region becomes 92% at B_T<=16.0 and 68% at
B_T<=18.0. The one of CGCG galaxies in the direction of the Coma-A1367
supercluster becomes 98%. The Virgo cluster membership estimates obtained on
morphological grounds by Binggeli et al. (1985) are confirmed in all cases.
However, several "possible members" classified as BCD (if in the cluster) are
found instead to be giant emission-line galaxies in the background of the Virgo
cluster
