Identifications, spectroscopic data and UBV photometry are given for six possible Seyfert galaxies. Four of these seem to be of types intermediate between Sy 1 and Sy 2. It is suggested that surveys for emission-line galaxies that do not depend upon the presence of an ultraviolet-excess may lead to estimates of higher space densities for Sy 2 and intermediate-type Seyfert galaxies.
