Janjukian. 1 —Typified by the section at Torquay in the parish of Jan Juc. 
Referred to the Eocene by Hall and Pritchard; to the (?)01igocene by Tate and 
Dennant; and to the Miocene by McCoy and Chapman. According to the 
present author the main development of marine strata of Tertiary age in 
Australia belongs to this continuous and gigantic phase of sedimentation. 
To this series belong the main water-bearing beds of the Mallee and Riverina 
artesian basin. Other well-known Janjukian beds are found at Grange 
Burn, Hamilton ; at Waurn Ponds and Batesford, near Geelong ; at Corio 
Bay ; and at Bairnsdale. The great polyzoal series of South Australia is 
also of this age. 
Kalimnan. 2 —This less important phase of sedimentation was named 
by Hall and Pritchard from its typical occurrence at Kalimna, in Gippsland. 
In the Mallee bores it forms a generally impervious stratum which seals down 
the lower freshwater supply, and stops the downward passage of the upper 
brackish waters. The Kalimnan can be referred to the Lower Pliocene 
(McCoy and Chapman), and is correlated with the Upper Aldingan beds and 
the upper or oyster beds of the Murray cliffs. Other localities for the Kalimnan 
series are Beaumaris and the upper beds at Grange Burn near Hamilton. 
Murravian. 3 —A term given by Professor Tate to denote the Tertiary 
series of the Lower Murray cliffs. They undoubtedly fall into two series 
(upper, and middle and lower) of about the same ages as those at Aldinga, 
although of different faunal aspects, viz., Miocene and Lower Pliocene, or 
Janjukian and Kalimnan. 
Werrikooian. 4 —This name was selected for the Upper Pliocene deposits 
of Limestone Creek, a tributary of the Glenelg River, in south-western 
Victoria. In the Mallee deposits, this series is represented by estuarine 
sands with brackish water and marine shells.
