In May, 1917, a imper was published by Chapman and Gabriel 

 in which was discussed the age of a bed of shells occurring in the 

 dune-reck at the n;cuth of the Hopkins River. The shells were 

 found to be of living species, but the facies was unlike that of 

 the assemblages new to' be gathered on the shore-line at that 

 locality. Comparison was also^ made of the data afforded by the 

 old dune-rocks here and elsewhere, and also of the tuffs of the 

 Camperdown district. Amongst others, the conclusions drawn 

 from the evidence submitted in the paper are: — 



The shell-bearing beds underlying the volcanic tuffs near to 

 Warrnambool belong to the same episode as the older dune-rock 

 accumulations of that locality and Sorrento and the swamp de- 

 posits under the tuffs of the Camperdown district. The deposit 

 belongs to the early Pleistocene, and this present fauna, being 

 cf an estuarine character, points to different geographical fea- 

 tures ■from those now prevailing, the brackish conditions postulated 

 antedating the rejuvenation of the present river system. More- 

 over, the wide lava-flow of newer basalt, extending from the
