In the presence of an external gravitational force, high-m quasikink modes of plasma are investigated. The modes become unstable for the mode number m below a certain critical value. A stability criterion is obtained, which is more stringent than Suydam's criterion. A dispersion relation for the modes quadratic in ω^2 is also derived. For a constant-pitch field, the growth rates of the modes are calculated and their contour map is presented. It is shown that the stability of the modes does not depend on β=2P/B^2 but B_<θ^2>/B^2 and the maximum growth rates exist only for k・B>0.
