Two unstable shell stars, ζ Tau and 48 Lib, are compared. In the Herman-Rojas (1974) and Rountree-Lesh (1968) classifications, both stars have luminosity class III. These stars show similar features in the variation of the intensities, the profiles, and the radial velocities of the shell lines. An attempt has been made to explain the evolution of these unstable features.
