thickness of the lacustrine bed is just. under 10 feet (3 metres). Prior to the 
locking of the Murray mouth the river locally was subject to a slight tidal flow. 
Its normal height at Murray Bridge has been estimated as approximately 5 to 7 
feet above sea level. The lacustrine bed, therefore, very clearly corresponds with 
the general height of the latest phase of Reedy Terrace, 65 feet (19-5 metres), 
as determined over 100 miles to the south. Lf this correlation can be accepted, 
some further data may be considered to support it. When traced downstream 
from Murray Bridge a terrace can be followed at the general height of the 
Burdett 50 feet (15 metre) terrace, It runs out into the air on the plateau at 
Tailem Bend (elevation by railway survey, 60 feet (18 metres) at Tailem Bend. 
This plateau can be interpreted as the strand plain with associated shoreface 
deposits of the Reedy Terrace. Between Tailem Bend and Burdett, the Murray 
has eut through false-bedded dune deposits composed of consolidated sands which 
are of Post-Pliocene age and whieh appear to represent shore dunes of a marine 
terrace behind which the Notopala lagoon may have been formed. 
In March, 1933, with C. Fenner the present writer examined the left bani: 
of the Murray at Section 339, Tlundred of Seymour, one mile downstream from 
Tailem Bend.

Specimens from four of the principal beds were submitted to the late Frederick 
Chapman whose identifications were: 
Bed ‘‘A.’’ Pale cream-coloured foraminiferal limestone, rather friable. Tnelnded 
are fragments of cherty material of a grey colour including foraminifera and 
polyzoa. Washings contain foraminifera (Tertularia gibbosa, Cassidulina 
subglabosa, Gultalina communis, Anomalina ammonoides), ostracoda, 
Cytherella lata and echinoid spines,
