We present BVRI broad band photometry and long slit spectroscopy for a sample of ten southern galaxies selected from the Aguero Catalogue of Peculiar Galaxies. The analysis of the images shows that only four galaxies of the sample are truly peculiar galaxies and four are normal spirals. The remaining two galaxies, a normal spiral and a SO, form an interacting pair. Despite the rather com- plicated structure of the peculiar galaxies we did not nd evidence of mergers in our analysis of images and rotation curves. Almost all galaxies in our sample show star forming re- gions with very blue colors, (B V ) ranging from 0.2 to 0.6. The SO galaxy shows a very interesting structure in the V I color map suggesting that star formation events have occurred in concentric annuli centered in the nucleus. In our photometric analysis we did not nd characteris- tics that could distinguish between normal and peculiar galaxies. We obtained the \pure-emission" line spectra for six galax- ies of the sample by subtracting appropriate templates. These templates correspond to ellipticals selected from our library of spectra. This subtraction technique provides a powerful tool to calculate line flux ratios uncontaminated by the underlying stellar population. Our spectroscopic analysis conrms that the spiral galaxy of the interacting system AM 2054 433 has a LINER- type nucleus. In the normal galaxy ESO 316 29 we nd evidence of a LINER nucleus and we report a new Seyfert 2 galaxy, AM 2054 433 N. For this SO galaxy the line flux ratios measured from the pure-emission spectrum are indicative of a Seyfert 2 rather than a LINER nucleus as it was previously reported by other authors.
