Query: Comment on ``New Class of Resonances at the Edge of the Two-Dimensional
  Electron Gas.''   A reproducible resonance structure in the conductance through an
incompressible strip in the quantized Hall regime was recently reported by
Zhitenev {\it et al}. Although the authors disfavored the explanation of the
conductance resonances based on resonant tunneling (RT) through an impurity
state, I believe that it should not be dismissed and can explain a number of
experimental observations very well. In particular, I point out a new
characteristic signature of RT in the quantized Hall regime: the quantization
of the slopes of the resonance tracks on the magnetic field-gate voltage plot.
