  A narrow state, which we label DsJ(2458)+, with mass 2458.0 +/- 1.0(stat.)
+/- 1.0(syst.) MeV/c^2, is observed in the inclusive Ds+ pi0 \gamma$ mass
distribution in 91 fb-1 of e^+e^- annihilation data recorded by the BABAR
detector at the PEP-II asymmetric-energy e^+e^- storage ring. The observed
width is consistent with the experimental resolution. The data favor decay
through Ds*(2112)+ pi0 rather than through DsJ*(2317)+ gamma. An analysis of
Ds+ pi0 data accounting for the influence of the DsJ(2458)+ produces a
DsJ*(2317)+ mass of 2317.3 +/- 0.4(stat.) +/- 0.8(syst.) MeV/c^2.
