Obs. — This appears to have been a very delicate fern : the 

 pinnules are very slender, or membranaceous, and variable in shape 

 according to their position on the frond. Locality : Newcastle 

 quoted also from Mulubimba. I have found it on the Dawson 

 River Q. L. (near Cracow Creek), and I think I recognised it from 

 the Bowen River coal fields (Q. L.) among some specimens from 

 Rosella, two miles above Havilah crossing " A marine bed con- 

 taining Goniatites woodsii, De Konn., Productus cor a, D'Orb.,

Sphenopteris alata, Brong., Hist. veg. foss., p. 361, pi. 127. 

 Frond tripinnate, rachis winged, pinnse pinnate, above pinnatificl 

 with decurrent sessile pinnules, lower pinnatificl, with three to six 

 bluntly toothed segments, upper ones inciso-dentate, veins either 

 simple or forked, diverging slightly into each lobe from the costa 

 at an acute angle. Hawkesbury River, Brongniart, Mulubimba. 

 M'Coy. 



This species was referred to Hymenophyllites grandini, Gbpp 

 by Goppert, which belongs to the old Carboniferous of Germany. 

 Prof. M'Coy, however, denies that either the one or the other 

 which follows are identical with that form. 



With reference to this species Dr. Feistmantel makes the 

 following remarks in his Fossil Flora of the Gondwana system, f 

 " I have to point out some confusion which arose about this 

 species. In his paper on " Sedimentary Formations in New 

 South Wales, published in Mines and Mineral Statistics, 1874, 

 page 186, the Rev. Mr. Clarke correlated this Sphenopteris alata 

 with the Carboniferous form known at first by the same namet and 

 later as Sphenopteris (Hymenophyllites grandini). The matter stands 

 however, as follows : — The Australian species was at first dis-
