42 Fossils collected at Wollumbilla, 



lation, of 857 feet above the sea. This would give to the 

 red sandstone cliffs an elevation of something under 2,000 

 feet, which is a not unusual elevation for the Hawkesbury 

 rocks in New South Wales. It might be added, that those 

 who would argue that these rocks are a member of the 

 Triassic group, would find confirmation in the fact, that on 

 the Castlereagh River, about 600 miles to the southward, 

 the formation is saliferous, and coal underlies it there. My 

 sole object in noticing these facts, is to place the subject 

 clearly before the reader, without venturing on any further 

 conclusions as to formations, the extreme points of which 

 (as far as the localities mentioned in this paper are con- 

 cerned) between Portland Bay and the Comet River, being 

 fully 1100 miles. 



Art. XIV. — Remarks on a Series of Fossils collected at 

 Wollumbilla, and transmitted by Rev. W. D. Clarke, of 

 Sydney. By Professor M'Coy. 



[Read 30th December, 1861.] 



Having been honoured by His Excellency Sir Henry 

 Barkly with a request that I should examine a series of 

 fossils recently collected at Wollumbilla, and forwarded to the 

 Rev. W. B. Clarke, of Sydney, who transmitted them to 

 His Excellency with the expression of a desire that I should 

 indicate the age of the rocks from which they were obtained, 

 I subjoin a rough list of the specimens, of which, however, 

 I have not written specific descriptions, as I understand Mr. 

 Clarke desires himself to publish some of the species, and to 

 send all the specimens home. It would also be necessary 

 before describing any of them to clear away adhering 

 matrix at present obscuring some of the characters, and 

 running a certain amount of risk of damaging the specimens 

 for which I had no authority. 



I can, however, with confidence pronounce, from the 



* Stutchbury. Report of 1st January, 1853. Nevertheless in his report of 

 1st August, 1854, Mr. S. says, " I now feel justified, from the examination of 

 so large a portion of the colony, to record my opinion in favour of the views 

 so strenuously advocated by the Rev. W. B. Clarke, of the more ancient 

 geological age of the coal-bearing strata than that assigned to it by several 

 high authorities in England." &c.
