Ui^per Palaeozoic and Mesozolc Fuss Us. 307 



Tlie above notes in Sir A. C. Gregory's letter relate to the 

 fossils from the districts of the Greenongh and Irwin Rivers, of 

 Mesozoic and Carbo-perniian ages respectively. The fossils from 

 the Greenough River were easily recognised. Any doubts about 

 the localities of the Palaeozoic fossils have been cleared up within 

 the last few months by the Hon. Sir A. C. Gregory, who very 

 kindly favoured us with further notes on the fossil localities. 

 Sir A. C. Gregory also stated that the West Australian fossils 

 wei'e not collected by himself personally, but were forwarded to 

 him by residents in the districts where he had previously 

 collected specimens. 



Since the original specimens of West Australian Mesozoic 

 fossils described by Charles Moore are, presumably, in the Bath 

 Museum, and other records of West Australian fossils are not 

 too numerous, it has been considered of sufficient interest and 

 importance to publish some notes on the collection now before us. 



The Palaeontological Literature op the West Coast 

 District. 



The ages of the fossiliferous beds of the Greenough River and 

 Irwin River districts were stated to be Mesozoic and Carboniferous 

 as early as 1861,^ by Mr. F. T. Gregory, who, however, classed the 

 Mesozoic fossils as doubtfully Cretaceous. A list of the fossils 

 sent to London with Mr. Gregory's paper was inserted by the 

 editor of the Quarterly Journal, Profes.sor (then Mr.) T. 

 Rupert Jones,-' who also referred to these fossils as of secondary 

 age. 



Charles Moore gave, in 1862, an account of some fossils 

 from West Australia, and referred them to the Me,sozoic 

 period.'^ 



Later, the same author, in a paper read before the Geological 

 Society of London,^ describing a series of fossils collected by 

 Messrs. Shenton and Clifton in Western Australia, referred the 

 strata which yielded them to the Middle Lias or the Lower
