Among non-marine genus-group names of Australian Gastropoda established by Tom Iredale (1880–1972), 42 were introduced without a description, and are thus unavailable under the International Code of Zoological Nomenclature. Several of these names were made available, often inadvertently, in subsequent literature, but others have remained unavailable. We clarify the nomenclatural availability of all 32 originally unavailable names, the nomenclatural availability of which was not subsequently properly assessed. Most notably, the names Arnemelassa, Figuladra, Malandena, Meridolum, Nannochloritis, and Turrisitala continue to be used in taxonomic literature to this day, although they are unavailable. Where no other available name can be applied, these genera are herein described as new (Arnemelassa n. gen., Figuladra n. gen., and Nannochloritis n. gen.) to stabilise the nomenclature of Australian non-marine gastropods.

由汤姆·埃雷代尔（Tom Iredale，1880–1972年）建立的澳大利亚腹足纲动物的非海洋属群名称中，有42种由于没有描述而被引入，因此在国际动物学命名法中是不可用的。这些名称中的几个在后来的文献中常常是无意中可用的，但是其他名称仍然不可用。我们澄清了所有32个原本不可用的名称在名称上的可用性，随后对其名称的可用性没有进行适当的评估。最著名的是Arnemelassa，Figuladra，Malandena，Meridolum，Nannochloritis和Turrisitala至今仍在分类学文献中使用，尽管尚不可用。在没有其他可用名称可用的地方，此处将这些属称为新属（Arnemelassa n。gen。，Figuladra n。gen。和Nannochloritis n。gen。），以稳定澳大利亚非海洋腹足动物的命名法。
