CLARKE COAL-FORMATION OF AUSTRALIA. 



359 



I have recently procured a species, with Pish, from the same divi- 

 sion, which in some respects resembles a Tceniopteris, but is probably 

 not such. It will be forwarded to England. In Tasmania, both in 

 1856 and in 1860, I examined carefully the section from Launceston 

 to Hobart Town, right through the island, and traced what I believe 

 to be an equivalent of my Wianamatta beds of New South "Wales, 

 from the neighbourhood of Spring Hill nearly to the Derwent. They 

 appear to be in great force about Green Ponds and up to Lovely 

 Banks, near which I found beds before unnoticed as fossiliferous, in 

 which are plants of a different character to any hitherto found in 

 that or this country. I will also forward them. 



The second division, or Hawkesbury Pocks, are in Strzelecki's 

 book classed as Pliocene* ; but the Fishes contained in them are 

 nearer to Platysomus and Pygojpterus than to any Tertiary genera ; 

 and over them the Wianamatta beds attain a thickness of from 800 to 

 1000 feet. No Plants from these rocks were sent to Cambridge, 

 because I had not then found any. But in the beds with the Pish 

 were Sphenopteris, &c, and in the massive sandstones, along the 

 Hawkesbury itself, I have found casts of large fronds like Odonto- 

 pteris. Neither in Victoria nor in Tasmania have I seen any beds 

 which I can consider the direct equivalents of these, either in mass 

 or in distinct resemblance ; but patches of sandstone underlying the 

 supposed Wianamatta beds, about the descent to Bagdad and Brighton, 

 occur in Tasmania, which might occupy their position. As Mr. 

 McCoy considers these two divisions with the third, or the work- 

 able coal-beds, to belong to the Oolite, it becomes important that the 

 new fossils should be examined. But Mr. Dana considers f that these 

 same three divisions belong to the true " Upper Carboniferous or 

 partly Permian." I have already alluded to the Pish Urosthenes 

 australis, on which in part, as well as on certain Plants, as Ncegge- 

 rathia elongata, Mr. Dana founded his opinion. 



The Plants from the third division (which cannot be separated from 

 the second, as the Hawkesbury Pocks cover and pass into the coal- 

 measures, containing coal-seams in their lowest masses) are, as indi- 

 cated by Professor McCoy's memoir, as follows : — 



Sphenophyllum (Vertebraria) australe. Glossopteris linearis. 



Sphenopteris lobifolia, Morris. Noeggerathia (Zeugophyllites) elongata, 



alata, 1 var. exilis, Morris. Morris. 



hastata. Phyllotheca australis, Brongn.

 to this division J.
