Nineteen pools distributed between nine different granite outcrops, all south of 32� s. in Western Australia, were studied from May to July 1977. Data on depth, conductivity, pH and temperature are presented. In all, 35 invertebrate taxa, mostly identified to species, were recorded.

The black-footed rock-wallaby (Petrogale lateralis) was once widespread and abundant in rock-piles and ranges in the Warburton region of Western Australia. However, by the 1970s a major decline in its distribution and abundance was apparent. Ranges and rock outcrops were searched with local Aboriginal people to document the past and present distribution and abundance of the species and Aboriginal knowledge of its ecology. The journals of explorers, prospectors and surveyors were examined for records of rock-wallabies. Geologists, dingo trappers and other people who had worked in the region since 1930 were interviewed to document more recent sightings. Extant, small populations of rock-wallabies were located in six ranges, where they were inhabiting extensive gabbro rock-piles and rugged quartzite gullies, often in close proximity to permanent water. None of the granite outcrops visited had extant populations. Continuing local extinctions suggest that surviving populations are under threat and management intervention is required for their long term conservation.

A review of the Australian endemic millipede genus Atelomastix reveals the presence of 28 species, including the type species A. albanyensis Attems, A. nigrescens Attems, and 25 new species from Western Australia, as well as A. solitaria Jeekel from Victoria. All species are from the high rainfall zone of southern Australia. The new species are: A. anancita, A. attemsi, A. bamfordi, A. brennani, A. culleni, A. danksi, A. dendritica, A. ellenae, A. flavognatha, A. francesae, A. gibsoni, A. grandis, A. julianneae, A. lengae, A. longbottomi, A. mainae, A. melindae, A. montana, A. poustiei, A. priona, A. psittacina, A. rubricephala, A. sarahae, A. tigrina and A. tumula. Most species are shown to have extremely small distributions and all are classified as short-range endemic species. Most species have been collected at very few locations, occurring in discontinuous habitats such as mountain ranges, islands, granite outcrops, or fragments of wet forest.

A phenetic study of morphological characters of the Drosera peltata complex (Droseraceae) supports the recognition of the following taxa: D. peltata from wetlands of south-eastern Australia; D. auriculata from south-eastern Australia and New Zealand; the morphologically variable D. hookeri from south-eastern Australia and northern New Zealand; the widespread D. lunata from southern and South-East Asia, as well as northern and north-eastern Australia; and the new species D. yilgarnensis R.P.Gibson & B.J.Conn is here described, from around granite outcrops of south-western Australia. D. bicolor from south-western Australia is recognised as a distinct species outside of the D. peltata complex. D. insolita, considered until recently as a distinct species, is reduced to synonymy of D. lunata. Phenotypic plasticity, vegetative similarity and fleetingly produced diagnostic floral and seed characters within the complex pose significant challenges in understanding the taxonomy of these taxa.

The new leptodactylid genus Megistolotis and new species Megistolotis lignarius are described from localities in northern Western Australia and the Northern Territory. M. lignarius inhabits scree slopes and escarpments. The male mating call is a single note resembling the striking of timber. The spawn clump is a foam nest anchored to stones at the edge of small, temporary pools, and the tadpoles have intense black bodies and fins, and suctorial mouths. Megistolotis is most closely related to the limnodynastine genera Limnodynastes and Heleioporus.

Two New Species

Paroster baylyi sp. n. and P. ursulae sp. n. are described from south-western Australia, and compared with the similar P. michaelseni Régimbart, 1908. Their median lobes, parameres, gonocoxae, gonocoxosterna and habitus are illustrated, and details about their unique habitats and water beetle coenoses are given. The two new species are the first dytiscids to be known breeding solely in temporarily water filled rock-holes—so-called “pan-gnammas”—in the Mallee zone of south-western Australia. The total number of described species in the genus Paroster Sharp, 1882 is now 11. Eight aquatic Coleoptera of the families Dytiscidae and Hydrophilidae are recorded from 13 pan-gnammas on four granite outcrops in south-western Australia.

Adult Plants

Material of a very small and distinctive species of Isoetes was sent by Miss Alison Baird in 1934 to Professor J. Walton, who kindly handed it over to me for examination. This species, hitherto undescribed, is here named Isoetes australis. The material, which consisted of plants of all ages from two-leaved sporelings up to adult plants, had been collected in 1930 from rock pools in granite outcrops at Bruce Rock, 150 miles inland from Perth, Western Australia.The following description is mainly based on Miss Baird's material, but I later received air-dried plants of the same species which had been grown by Professor T. G. B. Osborn in the Laboratory at Sydney. These plants had originally been collected by E. T. Bailey from the Bruce Rock locality in 1934. They proved to be viable and commenced growth within a few days when placed in water, and I was able to keep one of them alive for a period of two years, though only in a depauperate condition. Professor Osborn also sent me herbarium specimens, collected in the same locality by Bailey, and some of these plants, which had been completely dry for six months or longer, proved viable, though I was unable to grow them on for more than a few months.

Fox Control

The population dynamics of five remnant rock-wallaby populations (Petrogale lateralis) persisting on granite outcrops in the central wheatbelt region of Western Australia were monitored over a six year period. From 1979 to 1982 all populations remained relatively static or declined for unknown reasons, but circumstantial evidence implicated fox predation. A fox control program was implemented in 1982 on two outcrops and was maintained for four years with the result that the two resident rock-wallaby populations increased by 138 and 223%. Two rock-wallaby populations occupying sites not subjected to fox control declined by 14 and 85%, and the third population increased by 29%. It was concluded that the fox has probably been a significant factor in the demise and decline of native mammals in the past, and that surviving populations are still at risk. Control of predation pressure on nature reserves was shown to be feasible from a management perspective.
