Eight isolated dwarf galaxies with radial velocities between 350 and 500 km/s have been resolved into stars for the first time. Based on photometry of the brightest blue and red stars, we obtained the following distance estimates (in Mpc) for these galaxies: 6.5 (UGC 2684), 6.9 (NGC 2537), 6.8 (UGC 5288), 5.3 (UGC 5423), 6.2 (UGC 5672), 7.4 (UGC 5918), 5.4 (NGC 5023), and 5.1 (NGC 5229). A wide variety of morphological features is noted in the isolated galaxies under consideration, which is clearly attributable to a difference in their star-formation activity. The median value of individual estimates of the Hubble parameter H = V_0/D for these galaxies is 68 km/s per Mpc.
