Point contact tunneling data are reported in a multilayered high-T{sub c} cuprate (Cu,C)Ba{sub 2}Ca{sub 3}Cu{sub 4}O{sub 12+{delta}} with T{sub c} = 117 K. The tunneling spectra in the superconducting state (T << T{sub c}) display spectral features such as well-defined superconducting gap peak at {+-}{Delta} as well as dip-hump structures beyond the peaks. In some cases, the spectra with two-gaps have been observed, indicating the coexistence of two inequivalent superconducting layers. The statistical distribution of superconducting gap magnitude suggests two distinct kinds of superconducting gaps that may originate from two inequivalent CuO{sub 2} planes, a characteristic of multilayered cuprates with n {>=} 3.
