[vol. IX. 
is not correctly drawn in Mc’Clelland’s Report. I have had the opportunity of seeing in our 
collections the original specimen and another, and have had both drawn from nature. 
They exhibit a very different appearance from McClelland’s figure: about eight leaves pass 
out from a common stalk ; the middle leaves seem to have been the longest; the venation is 
peculiar and different from that of our forms of Glossopteris, Brgt. I have no doubt these 
specimens belong to Sagenopteris, Brgt.; but the specific name is inappropriate, and should, 
I think, be changed. 
d. Ttenioptekis, Brgt. 
The absence of Tceniopteris, Brgt,, in the Damuda group has been urged as one of 
the principal distinctions between that group and the Raj m aha 1, and a strong confirma¬ 
tion of the palaeozoic ago of the former. This view, however, is no longer tenable, 
for Glossopteris danaokles, Royl., figured by Royle in his work (1. c. PI. 2-9 ), is really 
a Tceniopteris, Brgt. The original specimen was from the Burdwan coal-formation, 
that is, from the Raniganj coal-field. I have not seeu the specimen, but I have no 
doubt about the fossil being Tceniopteris ; the venation proves it, as the veins are distinctly 
quite free at their base, and ouly dichotomous in their whole length. 
The specimen from the Burdwan ( Raniganj ) coal-field represented by Mc’Clelland 
in his Geological Report, PI. XV, figs. 13a, 10, under the name of Tceniopteris danceoides, 
Me’Clellaud, is of course also a true Tceniopteris, Brgt., and judging from the form of the 
frond and the distance between the veins, I am inclined to consider it the same as the species 
figured by Royle. In its broad leaves and distant venation this species presents a habit corre¬ 
sponding with that of triassic forms of the genus. There is another specimen in the collection 
of the Geological Survey from the Damuda formation of Burgo in the R a j m ah a 1 
hills which leads to the same conclusions as Eoyle’s and Mc’Clelland’s figures. Accidentally 
on the opposite side of this specimen are some fronds of Glossopteris, Brgt., thus proving 
the association of the two genera in the D a mud a rocks. 
Lastly, I have soon a broad-leaved true Tceniopteris, Brgt., from Kamthi, with very 
narrow veins, which resembles strongly Bunbury’s Glossopteris muscefolia, except that 
the veins do not anastomose near their base (1. c. PI. VIII, tig. 6), so that I will describe it 
under a different specific name. Besides this I think that Glossopteris stricta, Buub. (1. c. PI. 
IX, fig. 5) is also near to Tceniopteris, Brgt., and Sir C. Bunbury himself has figured a 
fragment of a Tceniopteris (1. c. PL X, fig. 2) as Tceniopteris danceoides (?) Mc’Cl. He 
may be right. It may therefore be stated without hesitation that together with Glossopteris, 
Brgt., there occur broad-leaved species of Tceniopteris, Brgt., with a mesozoic habitus, and 
that the latter afford additional evidence against the palaeozoic age of the Damuda Flora. 
e. Neukoptebis, Brgt. 
, When Prof Schimper described the fossil plants from the Vosges sandstone, he referred 
to the genus Neuroptens, Brgt., some forms which did not quite agree with the carboni¬ 
ferous species, although the nervaturo of the leaflets in these triassic forms is the same 
as m those from the carboniferous strata, the leaves of the former being, however, 
sirup y pinnate. Not wishing to establish a new genus, he divided the genus Neuropteris 
into two principal groups, of which one, the carboniferous type, includes species with bi- 
or multr-pmnate fronds; the other or triassic type comprises the forms with simply 
pinnate fronds which are found in the Gres bigurre (Bunter.)*
