The Rayleigh-Taylor instability of two superposed Walters B' elastico-viscous fluids is studied. For stable stratifications, the system is found to be stable or unstable under certain conditions. This is in contrast to the stability of two superposed Newtonian fluids where the system is stable for stable stratifications. However, the system is unstable for unstable stratifications. This problem has also been studied for electrically conducting Walters B' fluid in the presence of a variable horizontal magnetic field. For stable stratifications, the results are found to be the same as in the hydrodynamic case. However, for unstable stratifications, the magnetic field has astabilizing effect.
