| Abstract: | This paper provides the parametric expressions satisfied by the enumerating functions for rooted nearly cubicc-nets with the size and/or the root-vertex valency of the maps as the parameters via nonseparable nearly cubic maps. On this
basis, two explicit expressions of the functions can be derived by employing Lagrangian inversion.
