dc.description.abstract In order to elucidate the structure and evolution of barred and oval galaxies, over 300 of the more than 1000 galaxies in the current version of the Catalog of Southern ringed Galaxies are subclassified into ring/pseudoring categories. Photoelectric multicolor photometry of 29 ringed galaxies showing outer rings and pseudorings of the suspected outer Lindblad resonance types reveals nothing unusual about the global star formation rates. The galaxies have relatively normal colors for their type but slightly lower than average surface brightnesses. It is demonstrated that integrated colors (V-R)_T and (V-I)_T can be derived reasonably well by using standard RC2 color curves originally designed for (B-V)_T and (U-B)_T determinations. A comparison between the present integrated photoelectric parameters and those in the ESO-LV data base reveals good agreement on B-band magnitudes but not total R-band magnitudes or B-R colors. en_US
