Zusammenfassung:Results are reported of velocity measurements and spectrophotometry of AG Pegasi made from spectrograms of medium and high dispersion. Phases in the periodic variation of the spectrum are identified and recent spectral changes are noted. A variable Balmer emissionline progression is found in all spectra. About 70 absorption lines of the M-type spectrum have been identified and some of them measured for velocity.
