Abstract
New spectrophotometric observations of the Seyfert 1 galaxies IC 4329A and Arakelian 120 are presented. The low-ionization broad emission lines (as evidenced by Hβ) are strikingly similar. The so-called zero peak in the Balmer lines of these objects appears to be both broader than and blueshifted relative to the [O III] λλ4959, 5007 lines. It is apparently not a narrow-line component. We confirm that the Balmer line profiles in IC 4329A are variable in shape, and we demonstrate that the profile variations are very similar to those seen in Akn 120
