—venation well delineated—apparently a Sphenopteris ; ultimate 
leaflets small, obovate, and attached to the rachis by a small 
surface. 
Seed vessel ? of a Zamia ? 
The sandstone in Marshall’s garden yielded about five or six 
species of ferns, of which two are figured by “ Strzelecki,” 
plate vi. figs. 2, 3, 4, and 5. 
A third looks like a Stegania; is slender and nearly erect, the 
branches tapering elegantly, and in a delicate terminal leaflet; 
bipinnate, but as in sandstone usually the venation is indistinct. 
A fourth appears to be a Sphenopteris, having the greater 
breadth of the leaflet attached to the rachis. 
A fifth is a sessile looking fern of some four or five inches in 
length, with small leaflets at the lower part of the rachis, widen¬ 
ing as they ascend, and again tapering into a long terminal leaflet, 
so as to give the whole a lanceolate appearance. 
And a large fern, with a thick rachis, repeatedly subdivided, 
like that of the Pteris esculenta. The leaflets are however broad, 
and it may prove to be the same as the fourth. 
The sandstone of “ Spode’s” quarry is partially inter-stratified 
with thin beds of limestone, and throughout with seams of car¬ 
bonaceous matter, more or less schistose, and of various but 
trifling thickness; the which, though it contains abundant 
traces of vegetable remains, presents little sufficiently well 
defined to form any conclusion upon. There occurs in the sand¬ 
stone itself, a strap-shaped, palm-like, leaf, often 3 feet in length 
and 4 to 6 inches in breath. Of ferns, I found only one or two 
imperfect specimens in it. But I was fortunate enough to dis¬ 
cover a few inches in length of the impression of a jointed stem, 
terminating in a rounded cavity, partly lined with carbonaceous 
matter. The cavity was such as a cocoa-nut might be imagined 
to form. The stem had the appearance of a string of rounded 
bodies of vertebrm, and was not unlike the stem of the Lily 
Encrinite, as it is figured usually. It may have been the flower¬ 
ing spike of a palm or zamia. 
In a layer of soft shale, in the quarry, I also met with the 
impress of the tricuspid head, or flowering spike, of some
