„ parallela , Eeistm. Bowenfels. 
,, densinervis, n. sp. Bowenfels.

Gangamopteris angustifolia, M‘Coy. Guntawang, near Mudgce. 
,, Clarkeana, Eeistm. Bowenfels. 
Gangamopteris, M‘Cov ; no species named. Leaves of these genus 
were quoted by Mr. Clarke in his paper on the Oil-hearing 
Deposits of New South Wales (No. 25), from the Nattai Biver 
and from Becdy Creek. 
Caulopteris (?) Adamsi, Eeistm. Newcastle. 
ZeugophglUtes elongatus, Morr. Mulubimba (probably a Podoza - 
mites). Quoted only as doubtful from these rocks on account of 
Prof. J. D. Dana’s identifying it with his Nuggerathia elongate, 
which, however, appears to he different. 
Noggerathiopsis spathulata, Dana, sp. Illawarra. 
,, media, Dana, sp. Newcastle. 
JBracliyphyllum australe, Eeistm. 
Squamce (?) cycadearum vel (?) coniferarum. Newcastle. Age — 
Permian. 
6. Kawkesbury and Wianamatta Beds. — These beds overlie the New 
castle Coal Measures. By the Bev. Mr. Clarke these two sets were considered 
as quite distinct. Erom pahcontologicai reasons it appeared to me that these 
two groups, though in superposition, are very closely connected (See No. 43.).* 
Later on Mr. Tenison Woods tried to establish this close relation on strati- 
graphical grounds, and this to such a degree that he proposed to discontinue 
the name Wianamatta beds altogether (See No. 54.). In the most recent 
writings of Mr. Wilkinson, Prof. Stephens, Mr. Batte, &c., the Wianamatta 
beds are, however, again spoken of as distinct in their position above the 
Ilawkesbury rocks, and as such we must therefore consider them, but still 
maintaining the close palaeontological connection of both. 
The age of these beds seems now to he pretty well settled. At first 
there is their geological position; they overlie the Newcastle beds, but which, 
as appears from some sections observed by Mr. Wilkinson and Prof. Stephens 
* [Mr. Clarke’s phraseology on this point in the last edition of the “ Sedimentary Formations of New South 
Wales,” p. 72, is rather indefinite. He refers to a “partial or general erosion before the whole series of the 
Wianamatta strata were laid down,” but on the next page he speaks of the same genera of fish “that we find 
ranging from the Wianamatta down to the Coal-measures of Newcastle.” We have every reason to believe, 
therefore, that although Mr. Clarke acknowledged a partial physical break between the two groups of beds, he 
still regarded them as paleontologically united. — II. E., Jnr.]
