A search for {ital t{bar t}}{r arrow}{ital e}{mu}+{ital X} in {ital p{bar p}} collisions at {ital s}{bar {radical}} TeV is described. The production and decay of top-quark--antiquark pairs is considered in the context of the standard model. The analysis is based on data with an integrated luminosity of 4.4 pb{sup {minus}1} recorded with the Collider Detector at Fermilab. An upper limit on the {ital t{bar t}} cross section is obtained, and the top quark in the mass range 28--72 GeV/{ital c}{sup 2} is excluded at the 95% C.L. The same limits apply to a possible fourth-generation, charge {minus}1/3, {ital b}{prime} quark, decaying via the charged current.
