  Using ~13.7 fb^{-1} of e^+e^- collision data recorded at near the Upsilon(4S)
resonance by the CLEO II and CLEO II.V detector configurations on the Cornell
Electron Storage Ring, we present the world's most precise measurements of the
Sigma_c^0, Sigma_c^+, and Sigma_c^{++} charmed-baryon masses as well as the
first measurements of the intrinsic widths of the Sigma_c^0 and Sigma_c^{++}
baryons. We also report on the first observation and mass measurement of the
Sigma_c^{*+} charmed baryon, M(Sigma_c^{*+}) - M(Lambda_c^+) = (231.0 +-
1.1[stat] +- 2.0[syst]) MeV/c^2, and the first CLEO observation of the
Omega_c^0 baryon, for which we measure a mass M(Omega_c^0) = (2694.6 +-
2.6[stat] +- 1.9[syst]) MeV/c^2 from a sample of (40.4 +- 9.0[stat]) candidate
events. All new results are preliminary.
