The "exotic" mesons X(3872), X(3915), X(3930) and X(3940), have been searched for in their radiative production in the 586 pb-1 e+e- annihilation data taken with the CLEO-c detector at the ψ(4160) resonance, and their decay in the two modes, X→π+π-J/ψ and X→γJ/ψ, with J/ψ→μ+μ-. No evidence for any of the four mesons is found. Upper limits for the product branching fractions, B 1(ψ(4160)→γX)×B2(X→π +π-J/ψ,γJ/ψ) have been determined. The limits at 90% confidence level range from 0.7×10-4 to 1.8×10-4.
