are overlaid unconformably, and newer tlian tlierermo-Carboniferous rocks, in a depies- 
sion of which they hare been deposited, and on which they are resting uuconforniably. 
I understand from Professor Edgeworth David, who spent soine time in this^ district 
examining these beds, that Tceniopferis was met with in Mr. Christian s shaft in Foyle 
Park. I also found a few indistinct leaf-markings in shales in Foyle Park, but, with 
these exceptions, 1 believe no fossils have yet been found. . . . Evidence of contem- 
poraneous volcanic action is met with in Shaft I^o. 5, Waverley Creek, where fifty-seven 
and a half feet of tufaceous sandstone, containing white porphyritic particles, were 
passed through.” 
Mr. Eands estimates the thickness of the Coal Measure strata, in the neighbour- 
hood of Tooloombah and Deep Creek, at about five thousand feet. 
It may be remarked that the paucity of fossils in the Styx Coal Measures is a 
characteristic feature of the Burrum Coal Field also — whatever may be the value of such 
purely negative evidence. On the other hand, the presence of contemporaneous igneous 
rocks in the Styx Coal Measures is a point which the latter have in common with the 
Ipswich Coal Measures and not with those of Burrum, so far as is known.
