New direct-imaging data are presented for the disturbed spiral galaxy NGC 4319 (z = 0.005) and the apparently connected quasar-like object Markarian 205 (z = 0.072). Image processing of this CCD data reveals (1) an almost continuous luminous connection extending from Mrk 205 into the nucleus of the spiral galaxy; (2) a corresponding feature on the opposite side of the disk, appearing to link a bright UV knot with the nucleus; and (3) extensive morphological peculiarities in NGC 4319 that are consistent with hypothesized explosive nuclear activity. These data support the conclusion that NGC 4319 is an active spiral galaxy that recently ejected Mrk 205 from its nucleus.
