On some Fossil Plants 
“ Burdy House,” near Edinburgh; also what appears to be a 
variety of the preceding, not strictly dichotomous. 
Fern, like an Aspidium, bipinnate or more, ultimate leaflets 
set opposite and close (1 inch in length by g in breadth) on a 
strong bent rachis, leaflets entire edged—venation singularly well 
marked, and like that of Odontopteris. 
Fern—venation that of Sphenopteris and delicately preserved, 
bipinnate or more—ultimate leaflets, very short, alternate— 
slightly crenulated—broad and attached along their whole breadth 
to the rachis, and nearly at right angles. 
Zamia? Fronds pinnate, like those of a Blechnum, but with a 
parallel venation—leaflets about two inches long, from half an 
inch in breadth near the rachis, to g towards the distal end, 
which is truncated and somewhat like a swallow’s tail, 
Fragment of the leaflet of a Zamia? one inch in breadth, and 
probably only a larger individual of preceding. 
Fern—venation like that of Picopteris, but not very distinct, 
bipinnate—elegant and wavy, with appearance of venation along 
the outer edges of the leaflets, which are tooth-shaped, short, and 
set opposite on the rachis at an angle of about 45 a . 
Fern_bipinnate, with venation of a Neuropteris, and very 
beautifully impressed. Leaflets a perfect oval, broadest toward 
the base, where they are attached by a rather small neck to 
the rachis. 
Fern—with short oblong leaflets, alternately set on the rachis, 
and having a deep central vein, and slight traces of lateral veins 
going off at right angles. 
A small dichotomous bare stemmed plant, one and a half inch in 
height. 
An entire leaf of a beautifully delineated Neuropteris. 
Fern—tripinnate; the pinnae having rather a continuous crenu¬ 
lated margin upon a long narrow frond (like the leaf of the Banksia 
serrata) where the ultimate leaflets spring from the rachis they 
are distinct, with an even rouuded edge, but become decidedly 
continuous toward the apex, which is obtuse. 
Fern—figured by Strzelecki, plate vii. fig. 1. 
Fern—bipinnate, perhaps tripinnate, and probably arborescent
