The dispersion relation of surface quasistatic waves for a semibounded dusty plasma containing elongated and rotating dust grains is obtained. The analytic modes in the frequency range of dust acoustic waves are derived and discussed with the aid of some graphical solutions. It will be shown that surface dust acoustic waves become unstable when the dust rotation frequency is smaller than the dust acoustic frequency.
