ROOF of the COAL. SEAM in the SYDNEY 



HARBOUR COLLIERY. 



By W. S. Dun. 



[Communicated by permission of the Under Secretary for Mines.] 

 With Plate XLI. 



[Read before the Royal Society of N. S. Wales, December 6, 1911.] 



This brief note serves as a record of an addition to the 

 flora of the shales overlying the coal seam in the Sydney 

 Harbour Colliery already referred to in this Journal 1 — 

 Cladophlebls cf. Roylei, Arber, Sch i zone lira gondivanensis, 

 and Rliipidopsis ginkoides, Schmal.?, var. Sussmilchi, Dun. 



I am again indebted to Mr. O. A. Siissmilch for the loan 

 of the specimen here referred to as Tceniopteris, cf. 

 McClellandi, Oldham and Thomas. 



As preserved, the portion of the frond is seen to be 24 

 mm. in width, with a well marked and prominent midrib, 

 the venation slightly inclined, about two to the millimetre, 

 — the furcation is irregular, near the midrib and between 

 that and the margin, and not regularly developed. 



For comparison, reference may be made to the works of 

 Feistmantel, 2 Zeiller, 3 and others quoted in Arber's " The 

 Glossopteris Flora." 



No exactly similar frond has hitherto come to my notice 

 from Australian beds. It occurs abundantly in the Raj- 

 mahal Series of India of the Upper Gondwanas (Lower
