We present the inclusive photon spectra observed in ψ(3095) and ψ(3684) decays. The decay ψ(3684)→γχ(3415) is observed with a branching fraction of 0.075 ± 0.026. Evidence is presented for three intermediate states in the decay sequence ψ(3684)→γγψ(3095) with masses of 3504, 3543, and 3455 or 3340 MeV.
