then four feet of clay, eighteen feet of limestones with fine gravel, 

 four feet of yellow limestone and one hundred feet of alternating 

 liard and clayey limestones. Seeing that the ferruginous bed at 

 Underwood's contains Lower Pliocene fossils, the torrent gravel 

 "which rests upon it, on acount of' its different lithological structure, 

 will be post-Kalimnan. Allowing for the great physiographic

^changes which have taken place since Kalimnan times, the beds or 

 .gravel immediately following could hardly be younger than Upper 

 Pliocene or Werrikooian. That Dr. Hall was inclined to regard 

 these gravel beds as older, that is, of Kalimnan age, can be 

 gathered from his rem.arks in the paper on the Gippsland Lakes, ^ 

 Avhere he says : " Clear evidence of the age of the gravels is shown 

 at lied Bluff, near the mouth of Lake Tyers. Thtf cliffs here consist 

 of yellow^ and giey sands crowded with Arachnoides incisa, Tate, 

 and are of Kalimnan (? Miocene) age. The sandstones contain a 

 few quartz pebbles, which form intercalated sheets in the upper 

 part of the cliff." If, however, we regard this upper bed as dis- 

 tinct from the lower yellow and grey sands, w^e must necessarily 

 conclude that they are of later age than the echinoid-bearing sands,
