We employ a quark model based on quantum chromodynamics and tested against noncharmed baryons to predict masses and decay rates of ground-state and excited baryons containing one charmed quark. Among other conclusions, the calculations indicate that the orbitally excited ..lambda../sub c/ 1/2/sup -/ analogous to the ..lambda.. (1405) is stable against strong decays.
