An investigation is conducted into the peculiar combination of mean Balmer absorption strengths of 7-8 A and relatively red color observed in the 'E+A' spectra of galaxies in 3C 295 and similar high-redshift rich clusters. Models are computed for the spectral evolution of early-type galaxies undergoing starbursts, as well as for a model of a late-type galaxy in which stripping halts star formation. Bursts having a constant star-formation rate of about 0.5 Gyr duration cannot be distinguished from the stripped model in any of the indices that were compared.
