History Of

The life history of the halobiont ostracod M. henricae was studied over a 2.5-year period in Lake Bathurst, a slightly saline lake in New South Wales. Samples were collected monthly or bimonthly between March 1981 and May 1982 and weekly between August 1982 and June 1983. Relative abundance of all nine life stages (eight larval stages and one adult stage) in the samples was determined. Furthermore, in 10 selected monthly samples, sex-ratio, relative abundance of three female maturity stages and number of eggs in uteri of ovigerous females were monitored. Nearly all life stages were present throughout the year and M. henricae is thus a perennial form in Lake Bathurst. Relative abundance of life stages suggests that M. henricae produces three successive generations per year. The spring generation, hatched from eggs laid during winter, matures around November-December. Its larval development takes between 4 and 5 months. The summer generation matures after a larval development of 2.5 months; this short period is ascribed to more favourable temperatures. The autumn generation takes about 4 months to mature.

For the pediatrician curious enough to pursue the life history of his patient into its prenatal phase or the obstetrician interested in more than one of his two patients, this small book will be of great usefulness. Of the twenty-one chapters, twelve are by Australian or New Zealand workers, the Editor, a Professor of Obstetrics and Gynaecology at the University of New South Wales, among them. The international flavor is augmented by Swedish, German, and Scottish contributors.

History Of

Australian beachworms, recognized by specialists as one species Onuphis teres (Ehlers 1868), and by fishermen as a number of forms, were studied to determine whether more than one species was involved. Monthly sampling at a study site (Narrabeen, New South Wales) and collections from other localities were undertaken to study the morphology of beachworms, electrophoretic mobility of glucosephosphate isomerase and aspects of their life history. Three forms of beachworms-slimy, stumpy and kingworm-occur at the study site. Stumpies were found to be young kingworms, while slimy represents a separate species. The two species belong to Americonuphis Orensanz, 1974; the name is preoccupied and is replaced with Australonuphis. The holotype of A. teres is a kingworm and the closely related slimy is described as A. Parateres, sp. nov. Four other forms of beachworms were collected from northern New South Wales and Queensland: stripey, giant, wiry and white-headed wiry. These forms are referred to Onuphis. Stripey and giant are morphologically distinct and are described as O. taeniata, sp. nov., and O. gygis, sp. nov., respectively. Wiry and white-headed wiry belong to a polymorphic species described as O, mariahirsuta, sp. nov.

Descriptions of two new genera including five new species of Australian landhoppers are presented. Two new species are recorded from south-west Western Australia (Austrotroides pectinalis and A. occidentalis) and one each from the Adelaide area (A. crenatus), southern Victoria (Agilestia hyperocha) and southern Queensland-northern New South Wales (A. hylaea). Notes on the life history of Austrotoides crenatus are provided.

The presence of embryos in the mantle cavity of A. nigrescens was monitored over a 2-year period. A, nigrescens maintains some breeding individuals throughout the year but shows peak breeding during the late autumn, winter and early spring in the vicinity of Sydney, New South Wales, Australia. The larval stages of A. nigrescens are described from larvae reared in the laboratory. A. nigrescens larvae can be easily distinguished from other nauplii described from balanomorphs of New South Wales by their distinctive marginal spines and paired dorsal shield spines. The duration of larval development in A. nigrescens, 13-23 days, is similar to that of other Australian balanids and does not appear to accord with the concept that the distribution of Austromegabalanus species has involved long-range epiplanktonic dispersal. The separation of Austromegabaianus, Notomegabalanus and Megabalanus is supported by larva! differences.
