the Coma supercluster. Two objects constitute a pair of galaxies in the Coma supercluster. Six filler galaxies belong to the Cancer cluster, two are in the foreground of the Hercules supercluster and one is a member of A2197. The remaining galaxies are isolated supercluster objects. We assume a distance of 65 Mpc for A1367, 69 for Coma. Isolated supercluster objects are assumed at their redshift distance, using $\rm H_0=100~km~Mpc^{-1}~s^{-1}$. Col. 10: the cluster membership according to the less restrictive criterion of Gavazzi, Randone & Branchini (1995). A galaxy is considered a cluster member if it lies within the “caustic” associated with the cluster potential well. Col. 11: projected radial distance from the nearest cluster center (deg). Col. 12: morphological type (see Gavazzi & Boselli 1996). The classification was performed on the best photographic material available: a) the present frames; b) broad band CCD frames; c) KPNO 4m plates (for the two clusters); d) Palomar Sky Survey plates. The majority of galaxies in our sample have small angular size (1-2 arcmin), thus the classification error is probably up to 2 bins of Hubble type. In particular the overabundance of Pec and Irr objects reflects our classification inability. Given the distance of
