In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei. One of us (J.L.S.) had the opportunity* of extending the survey to the whole sky by inspecting the Hubble plate collection at Pasadena. The present discussion will be restricted to galaxies brighter than 11.0 photographic total magnitude (de Vaucouleurs 1963) in order to include in the sample the objects previously found in the southern sky. From 174 galaxies brighter than rnr = 11.0, 20 were found to have peculiar nuclei and are listed with magnitudes and morphological types in Table I. In order to avoid selection effects because of low-latitude obscuration and edge-on galaxies showing no nucleus, we retain only the 136 galaxies with latitudes higher than 20° and minor to major axis ratios b/a larger than 0.4. The values of b/a were deduced from the Reference Catalogue of Galaxies (de Vaucouleurs and de Vaucouleurs 1964 ) . As 20 galaxies with peculiar nuclei remain after this selection, the fraction of the sample with peculiar nuclei amounts to 14%.
