The south-eastern Australian helicarionid clade currently comprises six genera of snails and semislugs united by genital characters, including an epiphallic flagellum that produces a spiraling, spinose spermatophore, the absence of an epiphallic caecum, and the presence of at most a very short vagina. We comprehensively revise the taxonomy of this group based on comparative analyses of key morphological features and mitochondrial markers COI and 16S, revise the placement of several species described recently on the basis of shell morphology alone, and describe new taxa. The snail genus Brevisentis is monophyletic as currently understood, but includes an additional undescribed species from Wollemi National Park, New South Wales. Mysticarion is shown to contain four arboreal semislugs with wide, disjunct ranges, including one new species (Mysticarion obscurior sp. nov.). We synonymise Fastosarion staffordorum with Mysticarion hyalinus. The semislug Desidarion is synonymised with Parmavitrina, and we describe two new species of this genus, P. flavocarinata sp. nov. and P. maculosa sp. nov. The semi-arboreal semislug Cucullarion is herein included in the south-eastern Australian helicarionid clade based on morphological and genetic evidence, despite its more northerly distribution. Two small semislugs so far placed in Peloparion do not group together and a new genus, Ubiquitarion gen. nov., is described for Peloparion iridis. All of these genera, together with the semislug Helicarion (not included here), form a monophyletic radiation endemic to southeastern Australia.

The taxonomy of 65 species of unilocular Foraminifera from 12 locations along the central and southern coast of New South Wales and in Bass Strait is discussed and all species illustrated. Thirty new species are described. A morphological key for the identified genera is also presented. Brief notes are added on their occurrence and distribution.

Parmelia (subgen. Xanthoparmelia) barbatica, Parmelia (subgen. Xanthoparmelia) burmeisterii and Parmelia (subgen. Xanthoparmelia) pseudohypoleia are described as new from the Australian Capital Territory and New South Wales. The former two species are the first representatives of this subgenus to be described in which usnic acid, barbatic acid and 4-O-demethylbarbatic acid are the major secondary metabolites.

A general description of the disclimax communities in the south-eastem Riverina is presented.The disclimax communities are essentially the pastures developed on clearing some or all of the trees in the climax communities and grazing the herbaceous stratum. These pastures are discussed in relation to soil and the grazing factor. Notes on the occurrence of weeds and the possibilities of pasture improvement are given.

The evidence of taxonomic differentiation in the Australian pilchard is reviewed. Three major groups (called races), located respectively in eastern, south-eastern, and south-western Australian waters, are distinguished by differences in growth rate. The boundary zone of the two former is near the New South Wales-Victoria bolder, but it is not certain to which of the two latter races the South Australian fish belong. The two former races are sukdivided into smaller, more or less separate stocks (populations), which are distinguished mainly by differences in mean number of vertebrae and in abundance fluctuations. There are at least two such groups in the eastern race, which meet between Port Jackson and Jervis Bay, and at least two in the south-eastern race. The pilchards of Cook Strait, New Zealand, are probably distinct from those of any Australian locality.

Gackstroemia novae-zelandiae sp. nov. is added to the genus Gackstroemia, a genus confined to the south temperate. The new species has been previously included within G. weindorferi, and is endemic to New Zealand. Gackstroemia weindorferi of New Zealand and Australia (Tasmania, Victoria, and New South Wales) and G. alpina are also treated.

The freshwater snail genus Fluvidona (Gastropoda, Caenogastropoda, Rissooidea, Hydrobiidae) is reapprasied and described using anatomical, shell, radula and opercular characters. Five species, three of them new, are described, being differentiated using anatomical, shell and opercular character states. A sixth species, similar to the Fluvidona species, is described and is tentatively assigned to the genus Austropyrgus Cotton. All six species live in northern New South Wales and southern Queensland and all are from single localities or very restricted areas. All species live in small streams, although one was found aestivating in soil in the bed of a small dry creek. The new species placed in Austropyrgus, from the Bunya Mountains, Queensland, is widely separated from putative congeners that are found in southern New South Wales and other parts of south-eastern Australia.

Seven species of ampithoid amphipods are reported from subtidal macroalgae living in Port Jackson, Sydney, Australia. In the genus Ampithoe the Indo–West Pacific species Ampithoe kava Myers, 1985, is recorded for the first time from Australia, and two new species, A. caddi, sp. nov. and A. ngana, sp. nov., are described. One new species ofCymadusa,C. munnu, sp. nov., is described. The genera Exampithoe (Melanesius), Peramphithoe and Plumithoe are recorded for the first time from Australian waters. The new species E. (M.) kutti, sp. nov. and Peramphithoe parmerong, sp. nov. are described, and Plumithoe quadrimana (Haswell, 1879b), comb. nov. is redescribed and a neotype is selected. New ecological and behavioural information is presented for these species. A new key and diagnoses for all known genera of Ampithoidae are presented. Paradusa Ruffo, 1969 is synonomised with Cymadusa Savigny, 1816.Exampithoe (Melanesius) gracilipes Ledoyer, 1984 is transferred to Exampithoe (Exampithoe) and Cymadusa uncinata Stout, 1912 and C. variata Sheard, 1936 are transferred to Paragrubia.

New species of Aphelognathus, Belodina, Taoqupognathus, and Yaoxianognathus have been identified in the Late Ordovician Cliefden Caves Limestone Group in central-western New South Wales, Australia. Of the Aphelognathus species, Aphelognathus percivali n. sp. and A. webbyi n. sp. occur in the basal Gleesons Limestone Member and A. packhami n. sp. and A. stevensi n. sp. occur 30 m higher in the Wyoming Limestone Member. It seems likely from the similarity of several of the elements that A. packhami is closely related to A. percivali, and A. stevensi to A. webbyi. Yaoxianognathus wrighti n. sp. occurs in the Gleesons Limestone Member but not in the Wyoming Limestone Member. Belodina confluens, Belodina hillae n. sp., Belodina n. sp., Panderodus gracilis, Taoqupognathus philipi n. sp., and Phragmodus? tunguskaensis occur at both horizons. The conodonts suggest a middle to late Caradocian (mid-Shermanian to mid-Edenian) age for the lowest part of the Cliefden Caves Limestone. The occurrence in southeastern Australia of the forms Taoqupognathus, Yaoxianognathus, and Phragmodus? tunguskaensis suggest affinities to coeval faunas in China and eastern Siberia. The four new species of Aphelognathus are distinct from known species in the Late Ordovician of North America and Europe but they may help characterize a paleobiogeographic region that includes eastern Australia and southeast Asia.
