the great balance of palseontological evidence, in my opinion, 

 indicating rather the Lower Carboniferous age." * 



In the description of " The First Sketch of a Geological 

 Map of Australia," by Mr E. Brough Smyth, we are told that 

 the Carboniferous beds '•' extend from the south part of Vic- 

 toria to the northern parts of Queensland. . . . Professor 

 M'Coy has examined the fossils from these beds, and, after 

 giving careful consideration to all the evidence which is avail- 

 able, he lias come to the conclusion that the so-called Devonian 

 rocks of Queensland are in reality of Carboniferous age/'i* 



Lastly, Professor L. G. de Koninck considers Mr Etheridge 

 wrong in referring Procluctus cora, and " several other Car- 

 boniferous species," from Queensland to Devonian beds. J 



Upon the relative value of the determinations on which my 

 father based his conclusions, I am unable to pass an opinion, as 

 I have not examined the specimens. Be this as it may, how- 

 ever, it gives me infinite pleasure to be able to bring forward 

 further facts tending to show the general correctness of his 

 conclusions. 



B. Carboniferous (?) 



Only the more important localities under this heading will 

 be referred to at present : 



1. Pelican Creek, five miles north of Sonoma Station. — This 

 is a very interesting locality from the exclusive occurrence of 

 Strophalosia Clarkei and the specimens referred to S. Gerardi 

 (King ?). Of the former there are no less than forty-one 

 specimens in various degrees of preservation, and seven of the 

 latter. 



2. Pelican Creek, three-quarters of a mile above Sonoma 

 road-crossing. — At this locality a hard feruginous grit con- 

 tains Orthotetcs crenistria, var. senilis. This characteristic 

 shell was noticed by the late Mr Daintree as occurring in an 

 arenaceous limestone-band on the Pelican Creek, and over- 

 lying a coal-seam.§
