Data on 86 galaxies of apparent B magnitude 13.8-18.5 with UV continuum emission from the second Biurakan survey (Markarian and Stepanian, 1983 and 1984) are compiled in a table and used to determine the luminosity function. The distribution of apparent magnitudes is analyzed, correcting for absorption in the Galaxy; the method of Terebizh (1980) is used to estimate the luminosity function; and the results are presented in graphs and tables. The average spatial density of faint UV-continum galaxies is found to be 1.8/sq deg, about 8 percent of the density of field galaxies of the same luminosity in the luminosity range -16.5 to -21.5 mag and about 0.1/cu Mpc per unit of magnitude in the interval -12.5 to -15.5 mag, with about 10-13 percent Seyfert galaxies (when blue stellar objects and QSOs are not taken into account).
