An ${\ensuremath{\eta}}_{c}$ candidate state has been observed with a mass $M=2978\ifmmode\pm\else\textpm\fi{}9$ MeV and a natural line width $\ensuremath{\Gamma}l20$ MeV (90% confidence level) using the Crystal Ball NaI(T1) detector at SPEAR. Radiative transitions to this state are observed from ${\ensuremath{\psi}}^{\ensuremath{'}}(3684)$ and $\frac{J}{\ensuremath{\psi}}(3095)$ in the inclusive photon spectra. The branching fraction to this state from the ${\ensuremath{\psi}}^{\ensuremath{'}}$ is (0.43\ifmmode\pm\else\textpm\fi{}0.08\ifmmode\pm\else\textpm\fi{}0.18)%, where the errors are statistical and systematic, respectively. In addition, evidence is presented for the decay of this new state into $\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and an upper limit is presented on the decay into ${\ensuremath{\pi}}^{0}{K}^{+}{K}^{\ensuremath{-}}$.
