Making two assumptions regarding the analytical continuation of the external solution to the region Im..omega..<0, we give the asymptotic distribution for ..omega -->..infinity of the eigenfrequencies of a hot perfect fluid relativistic neutron star. It results that the real parts of the complex eigenfrequencies grow as the integers, while their imaginary parts grow as lnvertical-bar..omega../sub n/vertical-bar with coefficients depending inversely on the ''optical path'' of the uncoupled gravitational waves through the star.
