Scientific paper

Photometric and spectroscopic observations are presented for some existing Tololo emission-line galaxies along with a new list of such objects. The emission lines from more than 80% of Tololo galaxies seem to be produced by hot stars. About 2% are class 1 Seyferts, and less than 10% are class 2 Seyferts. Virtually all Tololo galaxies would be discovered with the criteria of a Markarian-type survey, but only about one-third of the Markarian galaxies have sufficiently strong emission lines to be included in the Tololo listings.
