CARBONIFEROUS AND PERMO-CARBONIFEROUS ROCKS, N.S.W. 267 



stone on the western side of the Paterson River valley, 

 immediately north of the township of Paterson itself, and 

 is shown in Plate XXI. Tuffs preponderate, but interstra- 

 tifled with them are thin beds of shale and in some of these 

 there are present abundant fossil plants. The following is 

 a list of those so far found: — 

 Equisi tales — 



Archceo-Calamites radiatus Brong. 

 Lycopodiales — 



Lepidodendron sp. Cyclostigma. 

 Filicales — 



Rhacopteris (Aneimites) inequilatera Feist. 

 ,, intermedia Feist. 



„ Romeri Feist. 



,, septentrionalis Feist. 



Archceopteris (? Rhacopteris) Wilkinsoni Feist. 



Cardiopteris polymorpha Dun. 



Sphenopteris Clarkei Dun. 



Rhacophyllum diver sif or me Eth. til. 



This flora, in which the genus Rhacopteris predominates, 

 both in variety and number of specimens is known as the 

 Rhacopteris flora and is quite different from that found in 

 the Lower Carboniferous beds of the same district, and 

 referred to on another page. Lepidodendron occurs, but is 

 rare. The correlation of the Burindi and Kuttung floras 

 with Carboniferous floras in other parts of the world is 

 dealt with by Dr. A. B. Walkom in Appendix I, Some thin 

 bands of impure coal are also found in this part of the 

 Kuttung Beds, but they are of no commercial value. 



The Paterson Rhyolite. — This flow is one of the most 

 widespread in the district and makes a most useful per- 

 sistent horizon always occurring at the junction of the 

 Mount Johnstone beds with the overlying glacial beds. It 

 varies from 150 to 300 feet in thickness, and in the hand- 

 specimen displays abundant phenocrysts of quartz and
