divide close to the midrib. The Author remarks of his species — “ The chief character, 
however, lies in the secondary veins ; they were not numerous, and somewhat distant 
from each other, showing regular intervals.” The number, of course, depends upon the 
size of the frond, but otherwise these remarks quite coincide with the characters of our 
frond. I am unable to make a closer comparison than with the above species, but 
Feistmantel remarks that If. crassmerms “ was of no very large size.” Herein lies a 
marked departure from our fern, and may perhaps constitute a difference, in which case 
I should feel disposed to regard this as undescribed, at any rate so far as Australian 
species are concerned. 
As preserved, the frond is fifteen inches in length, and, if perfect, would measure 
fully five in breadth. Want of space does not enable me to figure this fine fossil, but 
the apical portion of a second specimen on the same slab of stone is given (PI. 16, 
fig. 5) . As regards size, the only species with which it is in my power to compare it is 
If. lata, 0. and M.,* but here the frond is very delicate, and the veins fine and close, 
producing a far more tender leaf than that under consideration. 
The veins in the Australian specimen are fully one millimetre apart, and 
frequently one and a-half. Their regularity is a very marked feature, and the angle 
of divergence is usually a right angle, or but very slightly removed from it. No rule 
seems to exist as to the order of subdivision of the veins, but when they are dichotomous 
the split always takes place in close contiguity to the midrib. It is only towards the 
apex that the divergence assumes another angle, and then it is much more acute. The 
apex of the frond is shown in a second specimen, about six inches long, on the same slab. 
It is obtuse, but at the termination of the midrib sub-mucronate. Two and a-half 
inches from the apex the width of the frond is three inches.

Macrotjenopteeis, sp. 
Ohs. A portion of a frond which was originally at least four inches wide, generally 
resembles that of If. loianamatta, Feistm. On emerging from the midrib, or costa, 
the veins are strong and about one thirty-second of an inch apart, but after bifurcation 
they become exceedingly fine and close together. The subdivision takes place near 
the rachis, and in this it differs from the species above named, in which bifurcation is 
much nearer the margin of the pinnule. The late Eev. J. E. Tenison Woods remarked, 
when speaking of Af. “I have some similar specimens near Ipswich, but 
the dichotomy of the veins is near the rachis, and it may be a distinct species.” I take 
it that the present fossil is a similar one to that mentioned by the Eeverend Author, and 
if it should prove distinct, as I anticipate it will, it may be known as Ifacrofceniopteris 
Woodsi. An early opportunity will be taken to figure this interesting plant.
