Spectroscopic and two-color imaging of the environment of the bright, low-redshift quasar PG 1613 + 65 = Mkn 876 is presented. The quasar is situated in a poor cluster of galaxies of Abell richness class 0. The quasar's morphology includes a 25 arcsec long tidal tail emanating from the east side, 180 deg from the position angle of a secondary nucleus 1.9 arcsec from the main nucleus. The nebulous component of the quasar is analyzed and found to be more than twice as bright as a first-rank cluster galaxy. The average colors of the tidal tail and the main body are consistent with those of late-type spiral galaxies. The possibility that the quasar host is interacting with a very close neighbor is assessed, and the star-forming effects of such an interaction on the host galaxy are considered. 43 references.
