Bistable dark solitary wave solutions (bistable holes) to the generalized nonlinear Schrodinger equation are shown to exist in the normal dispersion regime for nonlinearities which are Kerr-like at low intensities I, rise sufficiently rapidly at intermediate I , and become Kerr-like again or approach a constant value at large I. The origin of the gaps in the energy surface reported by the authors in a recent publication (Opt. Lett., vol.14, p.509-11, 1989) is discussed. The collisional stability of the holes is also numerically examined and correlated with previous optical switching results
