This species is abundant in the whitish shales and clays of 
Mulubimba, N. S. Wales.

Ord. Gleichejjiaceje. 
Gleichenites odontopteroides (Mor.) sp. 
Syn. Pecopteris odontopteroides (Mor.) in Strzelecki’s N.S. Wales. 
Having obtained a finely preserved frond of this plant distinctly 
forked in the manner of Gleichenia, I have removed it from 
Pecopteris, in which it was placed by Mr. Morris, and transferred 
it to the order Gleicheniacece without hesitation ; and taking the 
verbal characters of Goppert’s genus Gleichenites—“ Frons di- 
cliotoma pinnata. Fructificatio hucusque ignota,”—I think there 
can be no objection to placing it in that genus, although very 
distinct from his two species G. artemisicefolius and G. critmi- 
folius. I might also suggest its relation to the Lias and Keuper 
genus Heptacarpus, with some of the German species of which .t 
generically coincides. 
In the sandstone of Clark’s Hill, N. S. Wales. 
Ord. Neuropterides. 
Odontopteris microphylla (M’Coy). 
Sp. Char. Bipinnate; pinnse alternate, oblique, narrow, about 
three lines wide and two inches long ; pinnules alternate, ob¬ 
lique, slightly connate at the base, obtusely elliptical, their 
length only equalling the width of their base; no midrib, 
secondary neuration indistinct. 
The only Odontopteris approaching this elegant species by its 
alternate pinnse and very short connected pinnules is the O. 
Schlotheimii (Br.), from which it is distinguished by the smaller 
size, much narrower and more oblique pinnae, and by the pinnules 
being proportionally smaller and elliptical instead of broadly 
rounded. The latter character also separates it from the so-called 
Pecopteris Desnoyersii (Br.) of the ‘Oolithe k Foug&res’ of 
Mamers, Sarthe. 
Common in the fine sandstone of Clark’s Hill, N. S. Wales, 
Otopteris, Lind, and Hut. 
With Messrs. Lindley and Hutton I use this term for those
