520 pal.eontoloc;y of Queensland, 



limestones of Chillagoe The limestones of both 



regions, as well as the associated strata, present, as regards 

 organic remains, a most striking contrast to the Devonian Lime- 

 stones of the Broken River and the Burdekin, both of which teem 

 with Corals and Brachiopods in perfect preservation." 



As Mr. Jack very justly observed, the calcareous stems from 

 the Dorothy Mine, and, the silicious from Zillmanton, are past 

 recognition, although in the former case the entire limestone is 

 made up of fragments of stems and separated ossicles. But we 

 now possess this much information as to the age of these lime- 

 stones. A portion of the Zillmanton stone bears the impression, 

 in excellent preservation, of the surface of a colony of Heliolites 

 purosa, on which both sets of tubes, the autopores and siphonopores, 

 are distinctly visible. Now, as Heliolites is a genus not known 

 aljove the Middle Devonian, it would seem very probable that the 

 Chillagoe and Zillmanton Limestones will also fall to the same 

 horizon as those of the Burdekin Downs and Reid's Gap, near 

 TownsA'ille, kc.
