The data were collected by the Belle detector at the KEKB $e^{+}$$e^{-}$ asymmetric-energy collider. No significant signals are found in the $\\Lambda_c^+\\eta$ mass spectrum, including the known $\\Lambda_c(2880)^+$ and $\\Lambda_c(2940)^+$. Clear $\\Lambda_c(2880)^+$ and $\\Lambda_c(2940)^+$ signals are observed in the $pD^0$ mass spectrum.
