Analysis of a sample of 61 paired (..delta..theta< or =90', ..delta..v/sub 0//c< or =4 x 10/sup -2/) QSOs from the Hewitt--Burbidge catalog shows that at least 18 (those with M/sub eff/< or =10/sup 16/ M/sub sun/) belong to distant pairs of clusters of galaxies. This conclusion rests both on the similarity of the N(M/sub eff/) distribution for QSO pairs to that for paired galaxy clusters and on the estimated probability that two QSOs will be in chance proximity with respect to their angular separation and redshifts.
