The possibility of propagating Korteweg-deVries solitons in a superfluid /sup 4/He film and in a superfluid /sup 4/He films overlayed by a /sup 3/He film is discussed. Various dispersive and nonlinear contribution tot he equation for the nonlinear modes of the films are analyzed. Conditions depending on the thickness of the films are obtained for the propagation of troughlike and bumplike solitons.
