clays underlying the Older Volcanic at Flemington and Ken- 

 sington to the Miocene, while the Schnapper Point beds were 

 called Oligocene. He gave a section, showing the relations of 

 the beds, from the Royal Park to the escarpment on the left 

 bank of the Saltwater River. The volcanic rock at South 

 Melbourne and West Melbourne is coloured on the quarter- 

 sheets as Lower Volcanic — that is, Lower Newer Volcanic — and 

 is so lettered except on Quarter-sheet 1, N.W., where the 

 lettering is V.O., i.e., Older Volcanic. Mr. Smyth showed that 

 the volcanic rocks of these areas are of the same age as those on 

 the west of the Moonee Ponds Creek, and are all " Older 

 Volcanic." He then clearly described the basin of Port Phillip, 

 pointing out the sequence of the beds accurately ; but it must be 

 borne in mind that the nomenclature is entirely different from 

 that adopted by the authors of the present paper. Another 

 point on which we differ from him is in the interpretation of 

 the sandy beds capping the hill along the south-west front of 

 Royal Park. Mr. Smyth regarded these as sand dunes, but they 

 are, in our opinion, an integral part of the upper series of marine 

 tertiary beds displayed in the railway cutting in Royal Park. 



In 1875 Mr. R. Etheridge, jun. (5), incidentally described a 

 cliff section near Mordialloc which had been visited by Aplin 

 and himself some years previously. As to the age of the beds, 

 he simply says that they had been " mapped by Mr. A. R. C. 

 Selwyn as of Pliocene age." 



In 1876, and during some succeeding years, Sir Frederick 

 McCoy (6) repeatedly referred to the fossil if erous beds of the 

 Brighton to Mordialloc coast and of Flemington. They were 

 classed together as of Older Pliocene Age. 



Some nine years later, Mr. Reginald A. F. Murray consolidated 

 the work of previous observers in Victorian Geology and referred 

 the Flemington and Brighton beds and the gravel of Flagstaff 

 Hill to the Pliocene Age. (7 p. 13). 



In 1888, Professor Ralph Tate (8) doubtfully classed the 

 Cheltenham beds as Miocene. 



In 1892, one of the present authors (11), acting on the advice 

 Professor Tate, classed the Cheltenham beds as Eocene. 



Early in the following year, Mr. T. S. Hart (12) gave the 

 results of prolonged, careful examination of the ix>cks of the
