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 
and 68% at 
.
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
Key words: galaxies: clusters; virgocluster / galaxies: distances and redshifts
