TINDALE—SUEDIVISION OF PLEISTOCENE 645 
The generalized contours which can be drawn on the present charts, unfor- 
fortunately are insufficient to give more than a few clues. The position also is 
complicated by the faet that Coolatoo channel was probably occupied by the Brown 
Cattle stream bed on more than one oceasion before it and its captured tributary, 
Reedy Creek, became diverted to Salt Creek and thence out towards Chinaman

From the above tentative indications the Post-EKast Avenue Terrace could have 
been at about 170 feet (—50 metres) and a Post-Woakwine low may have been at 
about —200 feet (-60 metres). More detailed bathymetric data is needed before 
the situation can be clarified. 
There are low-terrace deposits within the active zone of beach erosion off the 
present shore, Flat slabs of limestone are washed ashore on the present beach of 
the Coorong. One such slab of muddy limestone collected near Barker Knoll 
contained a shell fauna in which the dominant is a small species of Venerugns, 
either not now living or rare off the shore, 
SUBDIVISION OF PLEISTOCENE TIME IN SOUTIT AUSTRALIA, 
In the previous paragraphs data has been brought together to enable an 
attempt to be made at subdividing the Pleistocene. 
This data together with that of Lewis (1945) and Keble (1946) permits an 
attempt to consider the Tasmanian Pleistoceue glaciations in relation to the inter- 
glacial terraces of South Australia, and thus to prepare a preliminary correlation 
of the South Australian Pleistocene, 
Likely starting points for such a correlation appear to be either an identifiea- 
tion between the Millbrook Rise Stage of Lewis (1945), and the Milazzian inter- 
glacial, of Zeuner (1945), or a correlation between the ‘longest interglacial of 
Tasmania!’ (Pre-Yolande), the Tyrrhenian (or Great) Interglacial, and Kast, 
Avenue Terrace, greatest of the strand series in South Australia. 
Millbrook sediments fill the lower troughs of Malanna placial valleys to a 
height of 150 feet (45 metres) above present sea level. Were Tasmania an,
