Next, as to the marine bands in the Plant or Fresh-Water 

 Series, I have the following remarks to make. The Marine 

 bed at Eosella Creek contains Goniatites micromphalus (Morris) 

 and some indeterminable fragments of other MoUusca. The 

 similar bed at the Havilah-Byerwin Eoad contains magnifi- 

 cent specimens of a particularly characteristic Carboniferous 

 Brachiopod, Orthotetes {Streptorhynchus) crenistria, var. senilis 

 (Phillips), in company with Prockwtus brachythcerus (G. 

 Sowerby), No. 193, and a bivalve, either a Pachijdomus or 

 Astartila. 



Striking confirmation is again afforded by yet another 

 locality, Cockatoo Creek, where we have Glossojoteris and 

 Phyllotheca actually in company with Strophalosia Clarkei 

 (No. 176). 



The plants which characterise this Fresh- Water Series I 

 must now leave Mr Carruthers to describe. Beyond placing 

 these facts on record, I cannot at the present time go further, 

 pending the publication of Mr Jack's detailed report on the 

 Bowen Eiver coalfield. 



(Unforeseen circumstances have prevented Mr Carruthers 

 from carrying out his intention. The following is, however, 

 a list of his determinations) : 



1. Macarthur Creek, below Macarthur coal seam — 



Glossopteris Broivniana (Brong.) in great quantity. 



2. Jack's Creek — 



Arcmcaryoxylon iVitco^'i ^(Carruthers, sp. nov). 



3. Cockatoo Creek, 12 miles up — 



Phyllotheca Australis (Brong.). 

 Glossopteris Browniana (Brong.). 



4. Cockatoo Creek, 3^ miles up — 



Phyllotheca Australis (Brong.). 

 Glossopteris Browniana (Brong.). 



5. Cockatoo Creek, 11 miles up — 



Glossopteris Browniana (Brong.). 



6. Cockatoo Creek (Nos. 214 to 221 incl.)— 



Glossopteris linearis (M'Coy). 

 Phyllotheca Australis (Brong.). 

 Glossopteris Browniana (Brong.).
