A morph-frequency cline and a size cline are described for the snail Velacumantus australis. The frequency of a white-banded form decreases clinally with latitude South. Living populations from Queensland and northern New South Wales have frequencies between 7 and 18% whereas all populations from southern New South Wales and eastern Victoria, except those from Lake Illawarra, have frequencies between 2 and 5%. The frequency in Port Phillip Bay is less than 0.1%. The frequency in a sample from Swan River, Western Australia, was 9.1% about the same as in samples from localities of the same latitude on the eastern coast of Australia. The frequency in most fossil samples was similar to that in nearby living populations. The mean length of populations from the eastern states increases clinally with increase in latitude South, although there are some irregular fluctuations between adjacent populations which are probably influenced by population density.

Trace metal (Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn) concentrations in the fine fraction (<62.5 µm) of surficial sediments adjacent to the major urban centres of Sydney, Newcastle and Wollongong on the central New South Wales (NSW) continental margin, Australia, are elevated above regional background. The nature of enrichment off these major urban centres is distinct. The fine fractions of sediments adjacent to Newcastle are enriched in Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn, associated with the disposal of dredged harbour spoil in an offshore dumpsite, whereas adjacent to Sydney, enrichment of Cu, Pb and Zn in the fine fraction of sediments results mainly from the disposal of large volumes of sewage effluent. The source and regional dispersion of trace metals on the central-NSW continental margin can only be established from analysis of the fine fraction of the sediment, because total sediment distributions of contaminants are confounded by a highly variable sediment texture. Generally, low mud contents (<2%) and low concentrations of trace metals in inner-shelf sediment are evidence of efficient dispersal of fine material and associated contaminants on this high-energy continental margin.
