straight or incurved ; nerves close and numerous, somewhat thick 

 at the base, and from thence forking twice or oftener, becoming 

 slender and diverging into the leaf. 



This is a genus erected by Dr. Feistmantel in 1878,* for certain 

 leaves from the Talchir-Karharbari beds, which had been previously 

 classed as Noggerathia. To this latter genus had been referred 

 similar fossil plants from the Newcastle beds by Dana, and also 

 other leaves from the Jura rocks of the Altai mountains. A 

 comparison since made, has shown that the whole of these leaves 

 belong to closely allied plants, though Prof. Schmalhausen working 

 independently, has called his genus Rhiptozamites . In Australia, 

 they occur in paleozoic strata. In India, they are Liassic, and in 

 the Altai, Oolitic. They differ in many ways from true 

 Noggerathia, a genus which includes a very miscellaneous assort- 

 ment of plants. Some are probably Conifers and some Cycads, 

 while Dr/Heer suggests that Noeggerathiopsis is a connecting link 

 between the two. Dr. Feistmantel states (I.e. p. 156) that his 

 father had made the discovery of a true Fern fructification of 

 sporangia and spores in Noggerathia foliosa, Sternberg, of the 

 Bohemian coal measures, but this cannot be held to apply further 

 than to that one species. The species are not to be confounded 

 with either Schizoneura or Zeugopthyllites, as the venation of the 

 leaves clearly shows. 



Noeggerathiopsis spathulata, Dana (I.e., p. 715, pi. 12, f. 9.) 

 Leaves short, spathulate ; apex triangular and subacute, narrowed 

 at the base, and thence gradually dilating, nerves very delicate and 

 only partially distinct — four or five veins in the breadth of a line. 



In the figure given of this fossil by Dana there is a cluster of 

 leaves radiating from a common base, each nearly 2 J inches long. 

 "In this cluster,'' says Dana, "which is evidently a natural 

 group, the leaves are of different sizes. The younger are quite 

 narrow, oblanceolate ; length five times the greatest breadth, and 

 have a tapering apex. The older are nearly an inch broader 

 towards the apex, the base of the largest is but a little over l£ 

 lines, and from this base they widen till within half an inch of
