Abstract

An unlabelled group of irregular echinoids, donated to Museum Victoria, are identified as Maretia sp. aff. planulata (Lamarck, 1816) and their place of origin determined as the late Miocene Tambo River Formation at Swan Reach, East Gippsland. A comparison with the three extant species of the genus, M. planulata (Lamarck, 1816), M. carinata Bolau, 1873, and M.? cordata Mortensen, 1948, show Maretia sp. aff. planulata has a fair degree of similarity with the type species M. planulata. Because of this, and the lack of detail of certain diagnostic features on the specimens, the description has been left in open nomenclature. The fossil record of Maretia, currently considered to occur only within the Indo- Pacific region, is also listed and discussed.
