We have collected, from the literature (Table 1), the emission-line relative intensities in the spectral range 3700 Å-7000 Å for a sample of 177 nuclei of emission-line galaxies. According to the diagnostic diagrams of Baldwin, Phillips, and Terlevich (1981), the sample galaxies can be classified as Seyfert 2 (90 objects) or LINER (87), on the basis of their emission-line ratios.
