48 PERMO-CARBOMFEROUS FOSSILS FROM BANANA, ETC. 



doubtful whether there was any Middle Bowen formation on the 

 Upper Dawson. It was singular that Mr. Mackay's collection 

 should have been deficient in the characteristic Gympie fossils 

 brought to light by Mr. Bennett. The suggestion that the 

 Banana Creek (or Big Sandy Creek) limestone, from which Mr. 

 Mackay's fossils came, was identical with that of Kooingal from 

 which the late Mr. James Smith made a notable collection of 

 undoubted Gympie fossils was a strong point in support of Mr. 

 Bennett's position. The Cracow Creek fossils still remain to be 

 disposed of, but it must be confessed that their evidence is not, 

 by itself, very strong, since Chonetes Cracowensis is common to 

 Banana Creek, the Star formation, and the Kockhampton 

 division of the Gympie formation, and Platyschisma rotunda has 

 only been noted from Cracow Creek and the Gympie beds of 

 Rockhampton district. On the whole, pending the mapping of 

 the district, the Bowen formation had better be erased from the 

 geological map of the Upper Dawson, and the area added to the 

 Gympie formation. 



Mr. W. H. Rands, Assistant Government Geologist, also 

 spoke on the subject. He thought that Mr. Mackay's specimens 

 must have got mixed.
