We investigate a scenario in which a fourth generation quark {ital b}{prime} exists with mass {ital m}{sub {ital b}{prime}}{lt}{ital m}{sub {ital t}} such that flavor changing neutral current decay modes dominate its width. In this scenario the signatures of {ital b}{prime} quark production will be different than what have been examined so far at the Fermilab Tevatron and there are implications for {ital b}{prime} quark searches at {ital e}{sup +}{ital e}{sup {minus}} colliders. We study a flavor-distinguishing signature of the {ital b}{prime} quark production relevant in this scenario. We show that the background to this signature at CERN LEP 1 is not very large. At LEP 2 a suitable choice of cuts can make the background manageable.
