FOSSILS OF NEW SOUTH WALES. ALT 
The form of the frond is spatulate at all ages, it being widest about a third or a fourth of 
its length from the extremity, and attenuate below into the petiole ; and it is generally a 
little arcuate to one side, instead of being quite straight. The extremity is rounded or 
obtusely subtriangular. The midrib seldom exceeds a line in breadth below, and the 
petiole, a line and a half. The veins pass off at an angle of 30°, and curve outward, so 
as to make an angle of 50° with the midrib in specimens of medium size, and 65° or 70° 
in the largest specimens. The course of the veins is seen along the midrib in faint stria- 
tions, as observed in a natural cast in the enclosing clay. In a cast of a frond, the veins 
of one (the upper) surface are represented by raised lines; and those of the opposite 
(under) surface by linear depressions, having a slender raised line along the middle, as 
shown in figure 13 6, The spaces in the former are smooth; in the latter there is a 
minute transverse rugosity, which we have endeavoured to represent in the figure just 
referred to. 
Fig. 14, plate 12, may be a very young specimen of the above species.

Guossopreris ampia (Dana).—Frond very large and broad ovate, entire, undulate, 
apex obtuse. Midrib very stout and broad, ~ to 1 inch at base, and slender towards 
apex. Venation close, narrow, reticulate. Near the margin for nearly an inch, veins 
very much subdivided; more closely crowded, and scarcely reticulate. Spaces average 
7% of an inch in length, and 16 to 18 of them in breadth occupy half an inch, Near the 
margin there are 24or more toa half inch,—Plate 13, fig. 1 a, basal portion, natural size;

Newcastle and Illawarra. 
The full size of this species we cannot ascertain from our specimens, as the frond was 
evidently quite thin and tender, and is much broken. The breadth could not have been 
less than six inches, and the length probably exceeded considerably a foot. The fronds 
are often more or less in folds, and the folds pressed together. The veins pass off from 
the midrib with a curve, nearly as in the preceding species, but rather more abruptly. 
From the remarks already made on the changes which the Browniana undergoes from 
age, it is obvious that this species is quite distinct. 
GLossoPTERIS RETICULUM (Dana).—Large, oblong elliptical, breadth not over a third 
(a fourth?) of the length, gradually attenuate towards apex. Veins neatly and rather 
coarsely reticulate, the reticulations continuing almost or quite to the margin; spaces 
averaging one-third of an inch in length, and a sixteenth of an inch in breadth (or about 
8 to 4 an inch), angle of divergence from midrib about 65°.—Plate 13, fig. 2, part of a 
frond, 
Newcastle. 
This species has some resemblance to Brongniart’s second figure of the Browniana 
(fig. 2, pl. 62), in the coarseness and character of its reticulation ; but the veins do not so 
completely lose their reticulating character, and become parallel lines for a breadth of 
over half an inch along the margin, as in his Indian specimen, The specimen is 24 
inches broad 37 inches from the summit of the frond (which is probably not far from
