Oolite of Europe. Moore also recognised typical Cretaceous 

 fossils from this district. 



The Government Geologist for Western Australia (H. Y. L. 

 Brown), in 1873,' dealt in some detail with the stratigraphy of 

 the Greenough River district, and regarded these beds as of 

 Oolitic age. In the same report the chalky limestone of Gin Gin 

 and Yatheroo. which overlies the ammonite-bearing beds, is 

 referred to as most likely of Mesozoic age. A useful geological 

 map of the West Coast district accompanies this report, and the 

 horizontal sections give a good idea of the peculiar conformation 

 of this part of the country, with its characteristic flat-topped 

 ranges. 



H. P. Woodward (Government Geologist, W.A.) gave, in his 

 annual report for 1890-1891, a list of Mesozoic fossils ; but these 

 are all from the Victoria district. 



G. C. Crick has done good service in re-examining Chas. 

 Moore's original types of Jurassic Cephalopoda, as well as 

 describing many specimens from other collections, and which are 

 distributed among the Bath Museum, the Geological Society's 

 Museum and the Natural History Museum, London. This work 

 appeared in two papers, published in the "Geological Magazine," 

 in 1894- 



The Carbo-permian fossils of the Irwin River district came 

 from the area known as the " Coal-seam," which is about fifty 

 miles from the coast, on parallel 29°. The discovery of these 

 Carboniferous rocks was made as early as 1846 by the brothers 

 A. C, F. T. and H. C. Giegory f and the occurrence of associated 

 coal beds with a six-foot seam was recorded by Lt. Helpman, 

 R.K^ 



Although not dealing with the fossils of the Irwin River 

 district, Hudleston's notes on fossils from north of the Gascoyne 

 River' supply further knowledge of Upper Palaeozoic forms, and
