New spectral classifications of a number of Seyfert galaxies, as well as of other objects that are not but were earlier suspected of being Seyfert galaxies, are presented. Measured redshifts for all these objects are also given. Mrk 266 SW and Mrk 1066, two galaxies near the lower end of the Seyfert 2's and close to Liners (low-ionization nuclear emission-line regions), are studied spectrophotometrically. Their relative emission-line spectra agree much better with published models for photoionization by a low-luminosity power-law-like radiation source than by shock-wave heating. The spectra of Mrk 883 and Mrk 1320, which are borderline Seyfert galaxies, of Mrk 984, a double emission-line galaxy, and Mrk 1459, a galaxy photoionized by a hot-star population, are briefly discussed.
