DESCRIPTIONS OF POSSI Ls: 
I FOSSILS OF NEW SOUTH WALKS. 
Tue fossils of New South Wales here described come from four regions—the District of 
Illawarra, the Newcastle coal beds, the sandstone of Harper’s Hill, and the schistose sand- 
stone of Glendon on the Hunter. A valuable collection of specimens from Illawarra and 
Harper’s Hill were received from Major-General Barry. These localities were afterwards 
visited by the writer, who observed the same species in place, and added many others to 
the collections. Our indebtedness, also, to the Rev. Mr. Wilton of Newcastle, and Mrs. 
Scott of Glendon, for Glendon specimens, has been mentioned. 
We describe first the fossils of the sandstone below the coal beds, and next, those of 
the coal beds themselves. The former are nearly all zoological, embracing molluscs and 
some corals, The latter are vegetable, excepting a single fossil fish,
