Morphological and spectral studies of the galaxies Kaz 69 and Kaz 460 are reported. The observations were made on the 2.6-m telescope at the Byurakan Observatory using the VAGR multiaperture spectrograph. Isophotes of monochromatic images of the Hα, [NII] λ6584, and [SII] λ6717 lines are constructed. Densifications I and II are found to rotate with north-south oriented axes of rotation. The two densifications (“knots”) have all the kinematic and spectral properties of individual galaxies. It is assumed that Kaz 139 and the densifications I and II were ejected from the nucleus of Kaz 460 at different times, with Kaz 139 probably having been ejected first, although they may all have been ejected simultaneously with different velocities. Along with Kaz 460, these objects form a physical group of galaxies and, at the same time, are a consequence of the activity of the nucleus of Kaz 460.
