Before proceeding to describe the species of these three 

 formations in their respective order, I purpose giving a brief 

 outline of Queensland geology and palaeontology, in so far as 

 the districts from which the present collection was obtained 

 are concerned. To this section will be added some additional 

 notes forwarded by Mr Jack, and bearing on his collection. 

 The description of the species will next occupy attention, fol- 

 lowed by a few deductions drawn from a study of the species 

 in general, and in conclusion will be found a tolerably full 

 bibliographic list, bearing on the palseontology of Queensland 

 generally. The corals, which are few in number, have, in 

 conjunction with those collected in North Queensland by 

 Mr Daintree, formed the subject of a separate paper by 

 Prof. H. A. Nicholson, M.D., and myself 



The second part of the report will be occupied with a 

 description of the plant remains which accompany the Mol- 

 lusca now described. I have found it necessary to retain 

 these for further consideration, as I believe I am in a posi- 

 tion, from a study of them, to throw some additional light of 

 an important nature on the much vexed question of the age 

 of the Australian coal-beds. 



2. Geological and Pal^eontological Notes on the 

 Devonian, Carboniferous, and Cretaceous Beds of the 

 Fanning Eiver, Bowen Kiver, and Tate PtivER respect- 

 ively. — (1.) Devonian — Fanning Biver Limestone. — Mr Jack 

 writes * me that this limestone, from which a small packet of 

 fossils has been obtained, is the equivalent of Daintree's 

 Burdekin or Broken Eiver limestone, and is probably the 

 same as that of Eed Gap and Double Barrel Hill, where 

 a few obscure corals were met with; but the limestones 

 and accompanying strata are so metamorphosed that it has 

 been quite impossible to make much out of the specimens. 

 Speaking of his Burdekin limestone at Terrible Creek, the 

 late Mr Daintree observed that " the limestones, where little 

 alteration has taken place, are a mass of aggregated corals." f 

 These are the Lower Devonian or " Siluro-Devonian " beds of 

 my father's classification. He says, J " There cannot now be
