between the genera Cyclopteris and Glossopteris, for although the 
specimen I have drawn only exhibits the middle portion of the 
frond, yet I have ascertained that the form is precisely that of a 
narrow Glossopteris, being elliptical or pointed at the apex, and 
tapering gradually to a lengthened petiole at the base, and still 
further agreeing in the occasional anastomosing of the lateral 
veins, and their being connected, though rarely, by transverse 
bars; yet it is impossible to refer it to that genus from the want 
of the strong, characteristic midrib, the place of which is occupied 
by numerous dichotomous nerves of nearly the same thickness as 
those of the sides ; I am therefore obliged to refer it to Cyclopteris 
from a consideration of its more important characters, although 
differing remarkably in form from the other species of the genus 
as above restricted. The portion figured, of the middle of a frond 
measuring 3| inches in length, and 9 lines wide at the base, only 
tapers 2 lines. 
This species seems common in the gray shale of Guntawang 
Mudgee, N. S. Wales. 
Ord. Sphenopterides. 
Sphenopteris lobifolia (Mor.) 
Common in dark brown shale, Mulubimba, N. S. Wales. 
Sphenopteris alata (Br.) sp. 
Of large size in the fine gray sandstone of Mulubimba, N. S. W 
Sphenopteris hastata (M’Coy). 
Sp. Char. Bipinnate; pinnee long, acutely lanceolate, with a 
broad alate margin; pinnules elliptical, obscurely undulato- 
dentate, 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 distinguished this from any 
published species of the genus. The average length of the pinnee 
is about \\ inch, width 4 lines, average length of leaflets 3 lj nes . 
Not uncommon in the shale of Mulubimba, N. S. Wales. 
Sphenopteris germanus (M’Coy). 
Sp. Char. Bipinnate; pinnae oblique, alternate elongate, ovate 
with a narrow membranous margin; pinnules oval, deeply
