GALLERY.] NATURAL HISTORY. 197 
and polished specimens of wood from Antigua, &c. 
Whether or not Noggerathia flabelliformis and a related 
species are referable to them, remains doubtful. 
The upper division of Case 6 contains only specimens 
of Stigmaria , a genus totally distinct from any other 
known of the natural orders of Lycopodiaceas or Filices, 
to both of which its species have been referred by au¬ 
thors. Their internal structure, as proved by transversal 
sections of the stem, approximates to that of the Euphor- 
biacea:. Below these, in the same Case, are placed 
various interesting specimens belonging to species of 
genera of Conifers, such as Pinus, Araucaria , Thuytes , 
Volzia , Brachypliyllum , &c. In another part of the same 
Case are deposited interesting remains of the natural 
order of Cycade;e, (among which may be specified the 
fine specimens from the oolitic formation at Whitby,) of 
various species of Pterophyllum , Zamia , Ctenis , and (on 
the top of the Case) the globular trunks (two of them 
cut and polished) of Dr. Buckland’s Cycadites megalo - 
phylla. (Brongniart’s Mantellia nidiformis ,) from the 
oolite of Portland. Various other vegetable remains, 
especially of Dicotyledonous plants, such as those from 
the fresh water formation of Oeningen, &c., will hereafter 
be arranged in Table Cases to be made for their re¬ 
ception. 
On the lower shelves of the Cases 3, 4, and 5, is placed 
a very extensive series of cut and polished specimens of 
fossil wood, most of them from the red sandstone forma¬ 
tion of Chemnitz in Saxony, and New Paka in Bohemia, 
and many of them described and figured in Cotta’s work: 
Die Dendrolithen , Dresd. 1832. The genera Tubicaulis , 
Psaronius (Staar-stein) and Porosus , no doubt belong 
to the Filices; many of the remainder are referable to 
the Palms, and a still greater portion of them to the Coni- 
ferse ; in the vicinity of which natural orders they are 
respectively placed in the Wall Cases. 
The two Cases placed against the piers, between the 
windows of the E. wall of the room, contain a suite of 
varieties of Wood opal from Van Diemen’s Land, presented 
by Mrs. Howley, the lady of his Grace the Archbishop of 
Canterbury.
