We have made a statistical study of the optical and far-IR properties of all the Seyfert 2 galaxies in the catalog by Véron-Cetty and Véron (1987; hereafter VCV). Nuclear spectroscopic data were compiled from the literature and IR fluxes from the Catalogued Galaxies and Quasars Observed in the IRAS Survey (1985); we used only those IR fluxes not flagged as limits or uncertain values. We have used for comparison four more lists of objects with IRAS fluxes: one of Seyfert 1 galaxies given by Rodríguez Espinosa, Rudy and Jones (1987), a list of LINERs compiled from the literature, a sample of “normal” spirals (those labeled H in Keel, 1983), and finally the galaxies catalogued as Starburst nuclei galaxies in VCV.
