Upper bounds on the three neutral scalar Higgs masses are considered in the supersymmetric standard model with a gauge singlet Higgs field. When the lightest Higgs is singlet-dominated the second lightest Higgs is shown to lie near or below thetheoretical upper bound on the lightest Higgs mass. We also consider detectability of these Higgs bosons at a future e+e- linear collider with s∼ 300 GeV and show that at least one of the neutral scalar Higgs has a production cross section larger than 0.04 pb.
