One leaflet is very similar to leaflets of Sagenopteris rhoifolia, PresL 

 In this section (of uncertain ferns) also belongs that fern which I 

 have already quoted elsewhere as Actinopteris bengalensis, and the shape of 

 the leaves really resembles very much the form characteristic of this genus 

 as described by Prof. Schenk from the Rhatic formation. Our fossil is 

 from the Raniganj group. 



RnizoMES and Stalks. 

 There are several indeterminable fossils which have to be considered 

 as rhizomes and stalks of ferns. I shall refer to two only. 



Genus Rhizomopteris* Schimp. 

 Rhizomopteris balli,f Feistm. 

 1877. Rec. Geol. Survey, India, Vol. X, p. fig. 2-6. 



This form is quite characteristic, exhibiting distinctly the circular 

 sears and in some specimens also the dichotomy of the rhizome. 



Upper Gondwdnas ; Athgarh sandstone (Rajmahal group) near Athgarh, 

 Orissa. 



"Fern stem or rhizome. 

 1861. Bunbury, Sir. Ch. : Nagpur plants, Q. J. G. S. Vol. XVII, PI. XII. 

 Lower Gondwdnas : Shales at Miingli C. Prov., Wardha valley coalfield. 

 One or two specimens of a circinate vernation of a fern were also 

 found in the Rajmahal group of the Rajmahal hills. 



Glass LYCOPODIACEiE.t 



Remains of Lycopods are very rare in the Gondwana system. I can 

 only record one species. 



Genus Lycopodites,§ Sternb. 

 Lyeopodites graeilis,\\ Feistm.

1881. Eecords Geol. Survey of India, Vol. XIV, Pt. 1, pp. 150-151, PI. II, fig- 2. 



This fossil was previously classed with the Coniferae. 



Upper Gondwdnas: Rajmahal group, near Bindrabun, Rajmahal hills. 



Class CYCADEACE^ 

 Remains of cycadeaceous plants are very numerous, especially in the 

 upper portion of the Gondwana system, although they are also sufficiently
