Vol. 58. ] OF FOSSIL PLANTS FROM NEW SOUTH WALES. 7 
This second specimen corresponds exactly in nervation and contour 
to McCoy’s type. Prof. Zeiller’ has also figured a specimen 
of Gl. angustifolia with oblique nervation, and this again corre- 
sponds very closely with Gl. linearis. There seems, therefore, no 
good reason for regarding Gil. linearis, McCoy, as distinct from 
Gl. angustifolia, Brongt.; and as the latter is now known to be a 
form of Gl. Browniana, McCoy’s specimen can only be regarded as 
a variety of that plant. 
McCoy states that this plant is not uncommon in the hard 
siliceous schists of Arowa. Doubt has been thrown on this state- 
ment by several authors. JI have carefully examined all the 
specimens of Glossopteris in the collection, and I found no instance 
of any one being labelled ‘ Arowa,’ or occurring in a rock at all 
similar lithologically to that containing undoubted specimens from 
Arowa. I conclude, therefore, that McCoy was in error in regard 
to this statement.

In his remarks on Gl. Browniana, McCoy ? says that some of the 
fronds are of very large size. There is a specimen in the Clarke 
Collection, consisting of aslab of fine whitish sandstone, con- 
taining the impressions of four fragments, which are undoubtedly 
identical with the plant figured by Dana and Feistmantel as 
Gl. ampla. One of these, an apical portion, of probably the dorsal 
surface, is nearly 43 inches long, 4 inches across, and beautifully 
preserved. The apex is obtuse; the margin entire, and undulate. 
The strong median nerve does not, as Feistmantel* states, extend 
to the apex. At adistance of 34 inches from the apex, the median 
nerve is comparatively slender, and has begun to break up into a 
series of finer nerves, which, while at first pursuing a somewhat 
parallel course towards the apex, gradually diverge at a very acute 
angle, with regular dichotomy. ‘The nervation is fairly open in the 
area of about an inch on either side of the midrib, and not unlike 
that of Gl. Browniana. Towards the margin the nervation becomes 
closer and finer: the secondary nerves pursuing a pseudo-parallel, 
and oblique course, forming a very transversely elongate reticulation. 
Another fragment is a curved portion of a frond, 8 inches long, in 
which the lamina is folded on itself along the midrib. The midrib 
is very strong and flattened, + inch across. The close and fine 
pseudo-parallel reticulation at the margins is again very well shown. 
The justice of a specific value being assigned to this fossil is
