Radial velocity determinations for galaxies in the vicinity of NGC 7331, including the members of ‘Stephan's Quintet’, show clearly a superposition of at least two distinct physical systems. One includes NGC 7331, NGC 7320 (a Quintet member), and NGC 7343, while the other - seven or eight times more distant - contains the four remaining ‘Quintet’ constituents and six of the seven optical ‘companions’ of NGC 7331.
