J/A+AS/95/1 J/A+AS/95/1 Sample of dumb-bell galaxies in southern rich L Gregorini G Vettolani H R De Ruiter P Parma Astron. Astrophys. Suppl. Ser. 95 1 1992 1992A&AS...95....1G galaxies: clusters: general galaxies: elliptical and lenticular, cD We present two optically selected samples of dumb-bell galaxies extracted from the southern extension of the Abell catalogue and we discuss the selection criteria. The first sample is a volume limited sample obtained by selecting the dumb-bell galaxies in all the 171 clusters within a comoving distance of 210/h Mpc, regardless of Bautz-Morgan classification. The second sample is constituted by dumb-bell systems belonging to the 381 clusters of BM I or I-II type. From the latter sample it is not possible to extract a volume limited sample due to the selection effect present in the Bautz-Morgan classification of the southern Abell catalogue.
