One new species of the genus Antipathes and two new species of the genus Parantipathes are described from the coastal waters of South Australia. Antipathes antrocrada sp. novo resembles A. bifaria Brook, 1889 and A. lata Silberfeld, 1920, but differs from these two species in having 1ess crowded polyps, larger pinnular spines, and thinner pinnules that are more spreading and not as strongly directed distally. Parantipathes helicosticha sp. novo differs from the closely related P. tetrasticha (Pourtales, 1868) by having shorter pinnules, larger spines and smaller polyps. Parantipathes triadocrada sp. novo is similar to P. columnaris (Duchassaing, 1870), but is branched to a greater degree, does not have a reticulated worm run along the stem or branches, is extensively subpinnulated, and rarely has more than three pinnules or subpinnules in each verticil-like cluster.
