PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Mar. 20, 



certain Fishes with the so-called Jurassic plants ; for the fact that a 

 palaeozoic Fish was found in one of the pits at Newcastle in the 

 same block with the Plants in question, which are called Oolitic, has 

 not shaken faith in the latter assumption. Yet that fact must be 

 explained away before the view in question ought to be adopted. 



And if it should be found that certain genera, such as Glossopteris 

 and Sagenopteris, are not always of so recent date as the Jurassic 

 epochs ; if it should also be found that the supposed palaeozoic plants 

 {Lepidodendra, &c.) ascend higher than the Lower or Upper " Carbo- 

 niferous," then it may be that (which I have been inclined to believe 

 may be the case) there is an epochal as well as stratigraphical sac- 

 cession in the Australian coal-bearing beds. The only way to settle 

 the doubt unmistakeably would be to have a complete and careful 

 measurement made of all the beds supposed to be contemporaneous 

 in all the Australian colonies, and to collocate them after due inves- 

 tigation. 



But that is at present an "impossible quantity;" we must be 

 content with such evidence as we have ; and as a contribution to 

 the general data, I will make a few further remarks. 



In Victoria, the geological survey obtained in the early part of 

 this year a Tceniopteris from the neighbourhood of Cape Paterson, 

 and have recently obtained other plants of supposed like age from 

 the neighbourhood of Geelong. These fresh discoveries have been 

 taken to demonstrate the Oolitic age of that vicinity. Now, in my 

 examination of the Barrabool Hills, near Geelong, in 1856, I saw 

 enough to induce me to consider that the beds of that neighbour- 

 hood (especially about Ceres) belong to the first or upper divi- 

 sion of the New South "Wales series, and to my Wianamatta beds. 

 But the other divisions must not be forgotten. The four divisions 

 are — 1. Wianamatta Beds; 2. Hawkesbury Bocks; 3. {Workable) 

 Coal-beds; 4. " Lower Carboniferous Bocks " of McCoy : — 



1. Wianamatta Beds. Upper Carboniferous. 800 

 to 1000 feet thick.

In New South W r ales the W 7 ianamatta beds contain Fishes, which 

 are heterocercal and certainly not so near to Pholidophorus as to 

 Pal&oniscus, to which I consider some of them to belong. A species 

 of Phylhtheca, as well as Sphenopteris, is found in the same beds 

 with the Fishes ; and a Mytiloid shell accompanies them. 



The following Plants from this division I sent to Cambridge, and 

 they were determined by Mr. McCoy : — 



Gleichenites odontopteroides. Pecopteris tenuifolia, 



Odontopteris microphylla. 

 [Phyllotheca Hookeri is marked in the memoir from Clarke's Hill ; but it is a 

 mistake probably from accident, as that species belongs to much lower beds than 

 these.]
