The existence of a supercluster at approximately 18,000 km/s in the Horologium-Reticulum region is demonstrated. The principal constituents of the H-R supercluster are two rich clusters, Cl 0342-538 and 0329-527, one of which has an adjacent loose enhancement of galaxies, Cl 0326-537. A simple model indicates that the two main clusters of the H-R supercluster are at present approaching each other and will collide within 0.5 of a Hubble time. It is noted that a bridge (or filament) of galaxies connects Cl 0342-538 to the loose enhancements at Cl 0326-537. It is found that the position angles of the five bridge galaxies are significantly aligned along the direction of the bridge. A number of foreground groups are detected. One such system at 13,700 km/s covers most of the survey region, exhibits a velocity dispersion of only 210 km/s, and is similar to the G47 system observed in front of the Hercules supercluster. Several regions completely devoid of galaxies are identified.
