A search for charmed baryons decaying to D(0)p reveals two states: the Lambda(c)(2880)(+) baryon and a previously unobserved state at a mass of [2939.8 +/- 1.3(stat)+/- 1.0(syst)] MeV/c(2) and with an intrinsic width of [17.5 +/- 5.2(stat)+/- 5.9(syst)] MeV. Consistent and significant signals are observed for the K-pi(+) and K-pi(+)pi(-)pi(+) decay modes of the D-0 in 287 fb(-1) annihilation data recorded by the BABAR detector at a center-of-mass energy of 10.58 GeV. There is no evidence in the D(+)p spectrum of doubly charged partners. The mass and intrinsic width of the Lambda(c)(2880)(+) baryon and relative yield of the two baryons are also measured.
