This survey contains more than 3600 objects with mpg<19.5mag, half of them being galaxies and the other half being starlike objects. The aim of this work is to compile a complete sample of faint (B<17) Markarian galaxies. Here we present spectroscopic data for 185 galaxies, obtained with the 6m telescope of the Special Astrophysical Observatory in Russia and the 2.1m telescope of the Guillermo Haro Astrophysical Observatory in Mexico. In the present subsample, we find three new Seyfert 1 galaxies (SBS 0654+598, 1118+541, and 1320+551); one narrow-line Seyfert 1 (SBS 0748+499), one Seyfert 2 (SBS 0925+585), and three Seyfert2/LINER (SBS 0811+584, 1344+527, and 1428+529) galaxies; 12 LINERs; 13 blue compact dwarf galaxies; 65 starburst nuclei; 85 emission-line galaxies; and two absorption galaxies. Relevant astrophysical parameters (magnitude, redshift, relative intensities of emission lines, etc.) are given for the observed galaxies. File Summary:

Note (1): Redshift derived as the mean value of the redshifts of the strongest emission lines, corrected for solar motion (δz=0.001sin(l)cos(b)). Note (2): Logarithms of the observed and reddening-corrected relative intensities, normalized to Hβ or the Hα when Hβ was absent. Note (3): Morphological types as follows: Sy1 = Seyfert galaxies of types 1 Sy2 = Seyfert galaxies of types 2 SBN = starburst nucleus NLSy1 = narrow-line Seyfert 1 galaxy LINER = low-ionization nuclear emission region BCD = blue compact dwarf galaxy, M>-17.0 A colon denotes an uncertain spectral classification.
