The life of the two main divisions of the Queensland Cre- 

 taceous we now know to be practically the same, notwith- 

 standing the unconformability, at any rate, so far as the 

 fossils from the only localities in the Desert Sandstone 

 known to yield them permits us to form an opinion, viz. t 

 Maryborough on the East coast, Battle Oamp, near Oook- 

 town, also in the eastern division of Queensland, and 

 Croydon in the Gulf country. 1 



In New South Wales the two main divisions have been 

 recognised, but the work of the Geological Survey in the 

 Cretaceous area, has not, from unavoidable causes, so far 

 been of that detailed character as to permit a delimitation 

 to the same extent as in Queensland, except in the neigh- 

 bourhood of the White Cliffs Opal-field, westward to the 

 boundary of the colony, and north-westward beyond the 

 Paroo River, where recent explorations by Mr. E, F. Pitt- 

 man have revealed a much greater extent of the Upper 

 Cretaceous than was at first believed to exist. 2 The first 

 notification of beds answering in position to Daintree's 

 Desert Sandstone Series, in New South Wales, was, I 

 believe, made by Mr. H. Y. L. Brown, 3 and a reference of 

 the White Cliffs beds to the same subdivision by Mr. William 

 Anderson, 4 subsequently confirmed by J. B. Jaquet. 5 



Mr. E. F. Pittman in describing the Upper Cretaceous 

 rocks of New South Wales, says : — 



"The Upper Cretaceous Rocks. — After the close of the Lower 

 Cretaceous period there must have been a still further subsidence 

 of the floor of the basin, for the desert sandstones, which are of 

 marine origin are distributed over a much wider area than the
