Gen. Gangamopteris, McCoy. 
I have described already two species from our Damudas, i. e., Gangamopt. cyclop- 
teroides, Fstm.,* * * § and Gang. Hughesi, Fstm.f Mr. Wood-Mason brought also another, which 
differs from both by the much wider net-venation, which is also pretty constant in the 
size of the meshes of the net. I will describe it later with the name Gangamopteris 
Whittiana, Fstm., after Mr. Whitty, who contributed so much last year to our knowledge 
of the Karharbari flora by the magnificent slab of shale, covered with fine plant-impres¬ 
sions, contributed by him to our museum. I must still once more state that the Austra¬ 
lian Gangamopteris is from mesozoic strata in Victoria, together with Tamiopt, Dain- 
treei, McCoy. + 
Belemnopteris, nov. gen., Fstm. 
Amongst the ferns there is a wonderful specimen, which has its very close connection with 
the living Pteris sagittmfolia, Raddi§, and Uemionitis cordata, Roxb. Mr. Wood-Mason’s 
specimen has the same arrow-like shape; three primary veins, the chief primary veins 
stronger and more distinct; the secondary veins form a net-work of prevailingly hexagonal 
meshes. This specimen belongs to quite a new fossil genus which I call as above. The 
species I call in honor of Mr. Wood-Mason, Belemnopteris Wood- Masoniana, Fstm. 
Descriptions and discussions will be given later with the figure of the specimen. 
Of other ferns there is especially remarkable a very nice large specimen of an Alethop- 
teris form of the type of the living Phegopteris, a fructificating pinna of Alethopt. Lind- 
leyana, Eoyle, which belongs also to this group. 
Pal^ovittaeia, nov. gen., Fstm. 
Another new genus. Of much interest is another specimen with about eleven or twelve 
leaves coming out (as it seems) from a common spot; the leaves have the form of the meso¬ 
zoic Sagennpteris, Bgt.; they have an evanishing midrib (towards the apex); the secondary 
veins have nearly the same direction, but form no net-work, a circumstance which I think 
will establish this form as a new genus, as it cannot be well united with Tamiopteris, Bgt. 
I do not know anything in the fossil Flora closely similar with it. In the form of the 
leaves and their disposition there is an approaching similarity with Nceggerathia spathulata, 
Dana,|1 from Australia, but there the veins all are radiary, without auy midrib. 
There is also a slight resemblance with Chiropteris from the Iveuper^[; but the shape 
of the leaves, the direction and disposition of the veins, the total want of a distinct rachis, 
and the presence of several thicker veins, distinguish Chiropteris from our fern. 
I already now can say it is a new genus, allied only with the living Vittaria —so that 
I will call it Palceovittaria u. g., and the species Palceov. Kwrzi, Fstm. 
Of other plants I have still to mention several nice specimens of the Sphenophyllum 
trizygia, Urig., which $11 show again the great difi'erence of the Damuda forms from those in 
the coal-measures. 
These plants, brought by Mr. Wood-Mason, add considerably to our knowledge of the 
Damuda flora, and have especially yielded again strong evidence of its mesozoic age.
