description: We report the discovery of $Ξ_{c}(3055)^{0}$, observed by its decay into the final state $ΛD^{0}$, and present the first observation and evidence of the decays of $Ξ_c(3055)^{+}$ and $Ξ_c(3080)^{+}$ into $ΛD^{+}$. We also perform a combined analysis of the $ΛD^{+}$ with the $Σ_{c}^{++}K^{-}$ and $Σ_{c}^{\ast ++}K^{-}$ decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions ${\cal B}(Ξ_{c}(3055)^{+} \to ΛD^{+})/{\cal B}(Ξ_{c}(3055)^{+} \to Σ_{c}^{++}K^{-})=5.09\pm1.01\pm0.76$, ${\cal B}(Ξ_{c}(3080)^{+} \to ΛD^{+})/{\cal B}(Ξ_{c}(3080)^{+} \to Σ_{c}^{++}K^{-})=1.29\pm0.30\pm0.15$, and ${\cal B}(Ξ_{c}(3080)^{+} \to Σ_{c}^{\ast ++}K^{-})/{\cal B}(Ξ_{c}(3080)^{+} \to Σ_{c}^{++}K^{-})=1.07\pm0.27\pm0.01$, where the uncertainties are statistical and systematic. The analysis is performed using a 980 fb$^{-1}$ data sample collected with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider.
