alate margin; pinnules elliptical, obscurelj^ undulatodentate, 

 having three obsolete lobes on each side ; nerves bipinnate, two 

 branches reaching each lobe of the margin. 

 The lengthened oval form, slightly indented margin, and simple 

 neuration of the pinnules, fully distinguish this from any published 

 species of the genus. The average length of the pinnee is about 

 I5 inch, width 4 lines, average length of leaflets 3 lines. 

 Not uncommon in the shale of Mulubimba, N. S. Wales. 

 Sphenopteris germanus (M'Coy). PI. X. figs. 2 & 2 a. 

 Sp. Char. Bipinnate ; pinnae oblique, alternate elongate, ovate, 

 with a narrow membranous margin ; pinnules oval, deeply pin- 

 natifid; lobes very oblique, elliptical, generally three on each, 

 side, and the apex of the pinnules three lobed ; nerves bipinnate, 

 three branches reaching the margin of each lobe. 

 It is extremely difficult to distinguish this species from the 

 Pecopteris Murrayana of the Yorkshire oolitic coal-fields, with 

 which it is nearly identical in form and neuration. The oval outline 

 of the pinnules is the most obvious character, contrasting with the 

 trigonal, wide-based leaflets of the English plant; this, together 

 with their more oblique setting on the rachis, more oblique, narrow 

 and deeplj'^-cleft lobes, and the decurrent, narrow, alate margin to 

 the straight rachis, will I think be sufficient to distinguish the 

 species. 



In the shale of Mulubimba, N. S. Wales. 



Sphenopteris plumosa (M'Coy). PI. X. figs. 3 & 3 «. 

 Sp. Char. Bipinnate ; pinnae curved, elongate, narrow, plumose, 

 with a scarcely alate margin to the rachis ; pinnules close, oblique, 

 ovate, pointed, deeply cleft into about four oblique mucronate 

 lobes on each side, exclufive of the largely trilobed apex ; nerves 

 strong, much branched, so that about six branches reach the 

 margin of each of the lobes of the lower side, and seven to 

 each of those of the upper margin. 



The number of lobes of the leaflets and complexity of the neu- 

 ration will readily distinguish this species. The average length of 

 the leaflets 5 lines. 



Rare in the shale of Mulubimba, N. S. Wales. 



Sphenopteris flexuosa (M'Coy). PI. IX. figs. 4 & 4 a. 

 Sp. Char. Bipinnate; pinnae very long, with astronglyflexuousnaked 

 rachis ; pinnules large, moderately oblique, unequal, ovate, sides 

 cut into two very large obtusely rounded lobes on each side ; apex 

 trilobed; nerves strong, much branched, seven branches reaching 

 the margin of each lateral lobe, and three going into each of the 

 three lobes of the apex. 



This strongly marked species is not sufficiently allied to any 

 published form to render a comparison necessary. The average 

 length of the leaflets is about 8 lines, width 4 lines. 

 In a brown bed of clay, Mulubimba, N. S, Wales.
