Large-scale photographs and low-dispersion spectra obtained for 43 galaxies from Part II of Vorontsov-Vel'yaminov's (1977) Atlas of Interacting Galaxies are studied in order to search for examples of clumpy irregular galaxies and to perform a morphological and spectroscopic investigation of a sample from the cited Atlas. It is found that nearly half the galaxies have a normal Hubble morphological type, that one-sixth are morphologically peculiar, that more than half the galaxies exhibit emission lines, and that the presence of emission lines is apparently independent of morphology. Interesting objects noted include two possible cases of clumpy irregular galaxies, a possible very sinous chain, two spirals with 'blown up' arms, two cases of condensations located nearly symmetrically with respect to the nucleus, and one peculiar spiral with one very bright arc or arm.

Abstract
Large-scale photographs and low-dispersion spectra obtained for 43 galaxies from Part II of Vorontsov-Vel'yaminov's (1977) Atlas of Interacting Galaxies are studied in order to search for examples of clumpy irregular galaxies and to perform a morphological and spectroscopic investigation of a sample from the cited Atlas. It is found that nearly half the galaxies have a normal Hubble morphological type, that one-sixth are morphologically peculiar, that more than half the galaxies exhibit emission lines, and that the presence of emission lines is apparently independent of morphology. Interesting objects noted include two possible cases of clumpy irregular galaxies, a possible very sinous chain, two spirals with 'blown up' arms, two cases of condensations located nearly symmetrically with respect to the nucleus, and one peculiar spiral with one very bright arc or arm.Pubblicazioni consigliate
