Recent work strongly indicates that some types of morphological distortion of double radio sources occur only in sources associated with galaxies which are members of clusters. We therefore suggest that QSOs possessing similar distortions in their radio morphologies are also associated with clusters of galaxies. From available data we have determined that 3C 47, 3C 323.1, 3C 351 (all QSOs), and 3C 61.1 (possibly a QSO) all have radio morphologies indicative of cluster membership. Two of these objects, 3C 323.1 and 3C 61.1, are known to be members of clusters, and our observations indicate that 3C 47 may have an associated cluster. We suggest that investigation of QSOs with distorted radio morphologies would provide a sample of distant clusters of galaxies at known redshifts, allowing study of galaxy evolution, cluster X-ray source evolution, and possibly an accurate determination of q/sub 0/.
