360 O. Feistmantel — Contributions towards the [No. 4, 



In my Flora of Kach (Pal. Ind. XI, pt. 1, p. 22), I also speak of a 

 group of Aletlwpteris Whitlyensis, Gopp. (Lindl. and Hutt.), and on p. 27 

 enumerate all the species which I think can be brought into any connection 

 with it. 



Of our Indian fossils are to be placed here Alethopt. Whitlyensis, 

 Gopp. {Aletlwpteris tenuis, Bgt. sp.), Aletlwpteris indica, O. M., Alethop- 

 teris Lindleyana, Royl. sp. M. Saporta* has re-established for all these 

 mezozoic forms the genus Gladophlebis, with which they are to be ranged, 

 and this author has a Gladophlebis Whitlyensis, Gladoph. Bosserti, etc., 

 both of which latter he considers as scarcely distinguishable ; so that I 

 was right when I placed the Alethopt. indica, 0. M., the near relation- 

 ship of which to Alethopt. Bosserti, Schenk, cannot be denied, in the 

 group of Alethopt. Whitlyensis. 



Group of Aletlwpteris Whitbyensisf ("Schimper 1869, Feistmantel 1876.) 

 Of Mr. Wood-Mason's specimens one belongs here.

Fronde li-pinnata ; pinnis patentilus, rhachide eorum crassiore ; 

 pinnulis tota lasi sessililtis, attingentibus, ollonge-ovalibus, margine integris 

 aut sinuatis ; nervo medio usque ad apicem excurrente nervis secundariis 

 angulo subacnto eggredientibus dichotomis ; sporangiis ramis insidentibus. 

 (Feistmantel ex parte). 



Royle was the first to figure this species ; but he has given no descrip- 

 tion ; his specimen, too, could not have been a well-preserved one, but it 

 gives at any rate the form of the leaflets. 



In McClelland's Report (1. c.) we find added three figures more, which, 

 however, are very badly drawn, as also is his Pecopteris affinis (1. c. PI. 

 XIII. Fig. 11. a. b.), of which fig. 11 must certainly be placed with Alethop- 

 teris Lindleyana, Royl., while fig. 11 a. is a bad representation of the 

 same fern of which I give figures on pis. xvi. and xvii, and which, as I 

 think, belongs to another type of plants, and I have described it amougst 

 tbe Sphenopterides. The worst tbing in McClelland's figures is the veins 

 in the leaflets, which are quite unnatural. So it is also with his figures 

 of Alethopt. (Pecopt.) Lindleyana, Royl.
