to the same type of fossils, but our species is much more nearly allied to 

 the living Phegopteris than to any fossil species, 



Order T^ENIOPTEEIDES. 



In my preliminary ' Note on the Flora of the Damuda Series'* I have 

 already pointed out that the Damudas are by no means without a Taeniop- 

 teris, but that, on the contrary, forms of this order had been known for 

 several years from these rocks ; they occur especially in the Kamthi 

 and Baniganj groups (both of which, however, are of the same horizon) , 

 and also in the Barakur group. 



The majority of the Taeniopterides belong, as we know, to post- 

 palaeozoic epochs, the mezozoic epoch being especially rich in species of 

 this order. There are, it is true, some forms in the Permian formation, but 

 these are very rare and scarcely of any importance, while in the mezozoic 

 they are frequent. 



In the occurrence of this genus in the Damudas, I see a connecting 

 link between the lower and upper Grondwanas, as in these latter (Bajniahal 

 Series) analogous forms are very frequent. 



Brongniartf knew only the one genus Taeniopteris, but since his day 

 otber discoveries bave been made, so that Schimper in his ' Palaeont. veget.' 

 could give a pretty complete division of this order. 



In my Kach flora % I have given a close discussion of this order and need 

 therefore only shortly indicate here Schimper's division ; he distinguishes : — 



1. Taeniopteris, which he restricts to the few palaeozoic forms. 



2. Macrotaeniopteris, Schimp. especially mezozoic forms ; of Indian 

 specimens belong here the greatest part of the broad-leaved forms from 

 the Eajmahal Hills and besides these some forms from the Kamthi, Bani- 

 ganj, and Barakur groups. 



3. Ang iopteridium, Schimp., a mezozoic type, to which especially 

 some of the Bajniahal species belong and perhaps one from the Kamthis. 



4. Oleandridium, Schimp., begins in the mezozoic epoch. We have 

 one species from Kach. 



5. Danaeopsis, a Triassic form, but here found, as I think, in the 

 Liassic Eajmahal group. 



Marattiopsis, Sch., and Danaeides, Schimp., are of no interest for us. 

 •From this division the living affinities are plainly seen, and they particularly 

 are — 



Aspidmm Nidus for Macrotaeniopteris. 



Angiopteris for Angiopteridiwm.
