what association. Other mammals found at Queenscliff were the 
seal Otaria forsteri Lesson, and, in a cave, the dingo, Canis dingo 
Blumenbach. 
Gregory (1901) recorded an extinct kangaroo from near 
Sorrento. The fossil was in the consolidated dune rock (Upper 
Dune Series) between tides and, according to him, probably 
Palorchestes azael (Owen). 
Chapman (1919) identified a number of forms found in a shell 
marl in the Tootgarook (Boneo) Swamp, which rests on the Upper 
Dune Series, and listed both marine and freshwater species. These 
were, Pelecypoda : Erycina helmsi Hedley ; Gasteropoda : Coxiella 
striatula (Menke) and BulUnus acutispira Tryon; Crustacea: 
Cypris mytiloides G. S. Brady, G. sydneia King, C. tenuisculpta 
Chap., Candoncypris assimilis Sars., Cythere lubhockiana G. S. 
Brady and Limnocythere sicula Chap. He considered the presence 
of marine shells indicated some antiquity — a Pleistocene age. 
The core of the Sorrento Bore gave a record of the strati- 
graphical sequence of the Holocene and the Tertiary beds on the 
Nepean Bay Bar down to 1680 feet, and made it possible to 
correlate outcrops in other parts of the Port Phillip area. 
Nevertheless, as the samples were taken at intervals — some of 
them as far apart as 40 feet and others less than 10 feet, the 
average distance apart being about 20 feet — it constituted an 
imperfect record, not only of the Holocene and Tertiary succes- 
sion, but of the events leading up to, and connected with, the 
formation of the Bay Bar. Since, too, in the Holocene part of the 
bore, many of the fossils are foraminifera, a doubt arises, where 
the containing beds are intercalated with dune deposits, which here 
predominate, as to whether these tiny forms were not blown in by 
wind. There are some beds with a recorded fauna of one or two 
foraminifera, and perhaps an equally small polyzoan.
