We report results on inclusive production of the charmed baryon ${{\ensuremath{\Lambda}}_{c}}^{+}$ from ${e}^{+}{e}^{\ensuremath{-}}$ annihilations at $\sqrt{s}=10.5$ GeV. Measurements are presented of the inclusive cross section times branching fraction for the continuum production of ${{\ensuremath{\Lambda}}_{c}}^{+}$ as observed in six different decay modes, and of a new, improved value of the ${{\ensuremath{\Lambda}}_{c}}^{+}$ mass. The inclusive cross section times the branching fraction into $p{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ is measured to be 10.0\ifmmode\pm\else\textpm\fi{}1.5\ifmmode\pm\else\textpm\fi{}1.5 pb summed over all ${x}_{p}$. The branching fractions of ${{\ensuremath{\Lambda}}_{c}}^{+}$ into $p{\overline{K}}^{0}$, $p{\overline{K}}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, $\ensuremath{\Lambda}{\ensuremath{\pi}}^{+}$, $\ensuremath{\Lambda}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, and ${\ensuremath{\Xi}}^{\ensuremath{-}}{K}^{+}{\ensuremath{\pi}}^{+}$ relative to that into $p{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ are measured to be 0.44\ifmmode\pm\else\textpm\fi{}0.07\ifmmode\pm\else\textpm\fi{}0.05, 0.43\ifmmode\pm\else\textpm\fi{}0.12\ifmmode\pm\else\textpm\fi{}0.04, 0.18\ifmmode\pm\else\textpm\fi{}0.03\ifmmode\pm\else\textpm\fi{}0.03, 0.65\ifmmode\pm\else\textpm\fi{}0.11\ifmmode\pm\else\textpm\fi{}0.12, and 0.15\ifmmode\pm\else\textpm\fi{}0.04\ifmmode\pm\else\textpm\fi{}0.03, respectively. The ${{\ensuremath{\Lambda}}_{c}}^{+}$ mass is measured to be 2284.7\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.7 MeV/${\mathit{c}}^{2}$. The measured momentum distributions for continuum production of ${{\ensuremath{\Lambda}}_{c}}^{+}$ are compared to analytical fragmentation functions and to other measurements.
