Over 1000 type-specimens representing 253 nominal species of echinoderms from all five classes are listed. The majority of species have been described by H. L. Clark (1909, 1916, 1938) and are from Australian waters. However, 61 species are from Antarctic waters, these having been described by Koehler (1920–1926). Two species of asteroid, Ophidiaster propinquus Livingstone and O. watsoni Livingstone are considered to be synonyms of Linckia laevigata (Linnaeus) and Gomophia aegyptiaca Gray, respectively. The ophiuroid subspecies Ophiothrix stelligera atra H. L. Clark, as represented by two paratypes in the present collection, is considered a synonym of O. ciliaris rugosa Koehler. Ophiocoma alternans Endean, a homonym, is given a new name.
