At 09.00 h Eastern Daylight Saving Time on 8 December 1973 we observed a large turtle from the bow of the M. V. NELLA DAN. It was floating at the surface of the water with part of its carapace exposed, and swam slowly southwards out of the ship's path. According to the ship's log, NELLA DAN was at that time in Bass Strait in about 400 00' s, 147 degrees 02'E, travelling on a course of 309 degrees west of the Furneaux Group, Tasmania.

Fourteen brachiopod species belonging to the following genera are described from the middle Lower Devonian (Siegenian) Point Hibbs Limestone, Tasmania: Schizophoria, Isorthis, Cymostrophia, Megastrophia, Hipparionyx (?) ,"Chonetes" Machaeraria, Uncinulus, Hebeotoechia, Atrypa, Meristella, Athyris, Cyrtina, and Acrospirifer. Megastrophia hillae sp. nov., Hebeotoechia hibbensis sp. nov., and Acrospirifer banksi sp. nov. are erected. This fauna displays close affinity to faunas recorded from the Coopers Creek Formation, the Lilydale Limestone, and the Tabberabbera Formation of Victoria, and the Baton River Beds of New Zealand.

Several plants described by Labillardire and indicated to have been collected in Tasmania are shown to be species endemic to Western Australia. The locations are corrected and collectors are indicated if the original specimens could not have been collected by Labillardiere. The reasons for these errors are discussed and it is concluded that caution is required in accepting Labillardiere's type locations.

The littoral rock fauna of Dove Lake, Lakes Sorell and Crescent comprise 14, 26 and 20 species respectively. Within each lake the fauna varies greatly from rock to rock, but in general, rocks resting on stick or leaf litter harbor more individuals than those on rocks or pebbles. Between lakes there is an increase in biomass and a shift from dominance by insects to dominance by non-insects with increasing trophic status. Community structure of the littoral rock fauna in these lakes is compared to that in some European lakes.

The paper reviews previous ideas on the glaciation of Macquarie Island and gives an account of glacial landforms observed during a brief visit in 1972. The field evidence indicates that Macquarie Island was not completely overridden in an easterly direction by an ice sheet which developed on a broad submarine shelf to the west as advocated by L.R. Blake (in Mawson 1943). Local plateau, valley and cirque glaciers accumulated in depressions, basins and valleys on the surface of the plateau and at their maximum extent occupied about 40% of the island. A migration of the Antarctic Convergence from 150 - 200 km south of the island to north, of the island would depress sea level temperatures by 3-4 degrees; an amount adequate to account for the modest glaciation of the plateau surface. The majority of plant and animal species probably immigrated prior to the last glaciation, which is of Wisconsin age, and survived in non-glaciated areas of the present island and adjacent shelf to the west.

The sequence of tooth eruption in Sarcophilus harrisii was found to follow an anterior- posterior sequence with two exceptions. The first incisors of the upper jaw did not erupt until the cessation of suckling at about 200 days and the canines did not appear until after the commencement of molar eruption. Although considerable variation exists in the time and sequence of eruption of the teeth, the age of the young can be determined using shank length and weight in combination with the status of the teeth.

Eucalyptus delegatensis R.T. Baker, from a single seed source, was grown at five sites over a range of elevations from 260 m to 600 m on two soil types, in the Surrey Hills district of North West Tasmania. Seedlings were harvested twice, after 26 and 74 weeks of growth. Dry weight and leaf area were measured and at the second harvest the net assimilation rate was calculated for each elevation. The seedlings at the five elevations formed three significantly different populations, as discriminated on the basis of dry weight and leaf area. The differences in NAR can best be explained by variation in the length of the growing season, and the severity and duration of frosts over the altitudinal range. The population with the highest NAR (4.16gm sq dm -1 week-I) was grown below 300 m, in an area where Eucalyptus obliqua is the dominant wetsclerophyll forest species. The population with medium NAR (2.03 gm sq dm-1 week-1 ) was grown at three sites between 300 and 600 m, in an area where E. delegatensis wet sclerophyll forest is the -1 major vegetation type. The poor growth of the third population (NAR = 0.72 gm sq dm week - ), grown above 600 m, corresponds to an area in which E. delegatensis grassy woodlands, and Nothofagus cunninghamii rainforest are the predominant vegetation types.
