Sedimentary Formations 
I have also received a list of the genera of Walsh River fossils, 
in Mr. Etheridge’s handwriting. It is as follows, making all of 
them Lower Cretaceous :— 
Ammonites, allied to A. Cl/j - 
perform is. 
Ammonites sp. 
Crioceri. 
Bclemnites. 
Alyacites. 
Byssoarca. 
Solernya or Iridina. 
Area. 
Panopaea. 
Inoceramus. 
Hi unites or Avicula. 
Cytherea. 
Cyprina. 
Myoconcha. 
Pecten. 
Teredo or Teredina, in fossil 
wood. 
An opinion has been adopted that the Mesozoic fossils from 
Queensland, both those described by Air. Moore and these by 
Mr. Etheridge, were in mere drifted nodules. Air. Taylor assures 
me that such is not the case with the latter, and I long ago gave 
a section of the beds at Wollumbilla, proving, as in the York 
Peninsula, that the nodular masses were derived from a soft 
shale, being in fact concretions. If they have been drifted they 
have not travelled far. 
Air. Taylor {“limin's Report?' p. 13) seems to have found the 
shelly deposit before mentioned on “ a ilat-topped Carboniferous 
range” (on 9 Sept., 1872) ; and by a report of April, 1875, from 
Cook Town, it appears that a line seam of bituminous Coal has 
been, discovered at the junction of Oaky Creek and the Endea¬ 
vour River, 20 miles from Cook Town ; but from the determina¬ 
tion of Air. Carruthers, this Coal (confirming, however, Air. 
Taylor’s statement) is not of the Glossopteris age. The Coal of 
the latter series is not known to extend further north than 
20° 35' south. 
In 1S77 Professor Liversidge received from the Rev. G. Brown 
from Yew Britain and Yew Ireland (lat. 48° S. and long. 150° E.) 
some grotesque figures “ cut by the natives out of a soft white 
pulverulent material/’ said to be thrown up by earthquake 
waves, and “ having the appearance of plaster of Paris.” It 
holds numerous remains of Forarninifera?. 
The account of it is given in an interesting paper read before 
the Roy. Soe. Yew South Wales, and published in their Journal 
1877, vol. xi, pp. 85-91, “ On the Occurrence of Chalk in the Neio 
Britain Group." An analysis is given in comparison with Eng¬ 
lish chalk, which it certainly resembles ; but a doubt may be ex¬ 
pressed as to its being true chalk. Something like it, but less 
cretaceous, has been found in Yew Zealand, and I have found 
white calcareous fragments in the drifts of Y. S. AVales re¬ 
sembling it. Professor Liversidge adds, that no true chalk has
