Abstract:
It is proposed that Peculiar Ring Galaxies can be divided into five
principal types according to the morphology of the ring and bulge,
based on the visual inspection of 489 selected object. Those objects
have been named "peculiar" following the "Catalogue of Southern
Peculiar Galaxies and Associations" by Arp & Madore (1986,
Cat. <VII/170>).
