 COLLECT EVIDENCE AS TO GLACIAL ACTION IN AUS- 

 TRALASIA IN TERTIARY OR POST-TERTIARY TIME.

By Professor T. W. E. David. 



Only two reports have reached me on the above subject — the first 

 by Captain F. W. Hutton, F.R.S., and the other a short statement 

 by Mr. R. L. Jack, which, as it merely records the absence of 

 evidences of ice-action in Queensland in Tertiary or Post-Tertiary 

 rocks, is necessarily very brief. 



Queensland. — Mr. Jack states that hitherto he has been unable 

 to detect any evidence of ice-action in Queensland in rocks of Ter- 

 tiary or Post-Tertiary age, though, as already recorded by him,* there 

 is evidence in the shape of fjroups of travelled boulders of probable 

 ice-action in the Bowen Series (Permo-Carboniferous). Mr. Jack, 

 however, is of opinion that the extensive tin-bearing drifts at Stan- 

 thorpe, near the boundary between Queensland and New South 

 Wales, probably imply a Pluvial Epoch. The evidence is as yet 

 insufficient as to the exact geological age of these deposits, but they 

 are probably either Pleistocene or Pliocene, these terms being used 

 of course to express only a general homotaxial relationship to beds 

 of that age. Biological arguments are in favor of a Pluvial Epoch 

 in Queensland. Mr. R. Etheridge, jun., has called my attention to 

 the fact that crocodilian remains referable to PaUimnarchus pollens 

 have been recorded by M r. C. W. de Vis from the Condamine beds 

 (late Tertiary or Pleistocene) and also from near Brisbane from a 

 similar geological horizon. Teeth and coprolites of crocodile, 

 also referred by Mr. de Vis to Pallimnarclms pollens, have been 

 obtained from the Warburton River (Diamentina).
