246 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Apr. 2, 



15. Lamellibranchiate bivalve of a new genus, between Mo- 



diola and Pachydomus. 



16. Maeonia or Astartilla. 



17. Lamellibranchiate bivalve of a new genus. 



18. Avicula. 



19. Small Orthoceras (?). 



20. Belemnites, like B. giganteus, and proposed by Mr. W. B. 



Clarke to be termed B. BarTdyi. 



21. Area. 



22. Nucula. 



23. Modiola-Kke shell. 



24. PossU Wood. 



2b. LameUiferous Coral (very like a fossil from the Wiana- 



matta beds, N. S. Wales). 

 2Q. Fossils, very like fish-teeth, but considered by Mr. M'Coy 



to be the spines of the suckers of probably No. 20. 



27. ? Scalpellum. 



28. Sponge. 



29. Belemnites (like B. paxillosus). 



30. Dentalium. 



There are several other fossils, not yet examined, besides the above. 

 There are three casts of, probably, Eurydesma or Astartilla. These 

 come from Pitzroy Downs, about 13 miles N.W. from Wollumbilla. 

 Professor M'Coy considers them to be of diiferent age from the pre- 

 ceding. 



Moreover I submitted to him three Permian fossils, which I have 

 long had in my cabinet, from the Mantuan Downs, 200 miles north 

 of Wollumbilla, and which he has confirmed as such, viz., two very 

 like Productus calva, Sow. (I have another in my collection which 

 I believe to be identical with that species), and one allied to Aulo- 

 steges or StropJialosia, by which latter name I have marked it. These, 

 being shells which belong to the Magnesian Limestone, indicate the 

 Permian epoch. 



I have had also lately some fossils which were found on the Dawson 

 River, consisting of Producta and columns of Cyathocrinus, and are 

 therefore either Permian or Carboniferous. 



Any further notice of these Queensland fossils, with their bearing 

 on doubtful opinions, must be deferred. 



Mr. M^Coy believes the Wollumbilla fossils to be the marine re- 

 presentatives of the so-caUed Jurassic Coal-beds of New South Wales. 

 My own opinion is that they represent the marine life of the Wiana- 

 matta formation, and are nearer Trias than anything else ; and with 

 this the Fitzroy Down fossils and the Eed Sandstones of the Amby 

 would well agree in local position and other circumstances. I feel 

 confident, from what I personally Imow of the region from which they 

 come, that they are altogether above the Coal-beds of the Hunter 

 Eiver and lUawarra, distant about 530 miles, and of which there 

 are representatives, with the Newcastle coal-plants, about 200 miles 

 further N.W. at the junction of the Comet River with the
