70 NATURAL HISTORY. (Fossils.) [NORTH 
sented to the Museum. To these are added very perfect specimens, 
from Dr. Mantell’s collection, of the Clathraria Lyellii from the Weal- 
den : the generic name, formerly synonymous with Sigillaria, is now ex¬ 
clusively given to this remarkable vegetable. Sternbergia transversa 
of Artis, (Artisia of Sternberg,) hitherto described and figured from 
very imperfect specimens, also probably belongs to this natural order. 
Another interesting vegetable of Dr. Mantell’s discovery is the Endo - 
genites erosa, of which many specimens from Hastings, &c., are de¬ 
posited, exhibiting its structure : it seems related to the Palmse, and is 
no doubt a congener of Cotta’s Porosus marginatus, of which a speci¬ 
men is added ; but neither of those generic appellations appear to be 
admissible. There are also remains of real Palm^e in this Case, such 
as the fruits from Sheppey, the cut and polished specimens of wood from 
Antigua, &c. Whether or not Noggerathia flabelliformis and a related 
species are referable to them, remains doubthil. 
The upper division of Case 6 contains only specimens of Stigmaria, 
a genus totally distinct from any other known of the natural orders of 
Lycopodiacese or Filices, to both of which its species have been referred 
by authors. Below these, in the same Case, are placed various in¬ 
teresting specimens belonging to species of genera of Conifers, 
such as Pinus , Araucaria , Thuytes , Volzia, Brachyphyllum , &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 
Mantellia nidiformis of Brongniart, from the oolite of Portland_ 
Various other vegetable remains, especially of Dicotyledonous plants, 
such as those from the freshwater formation of Oeningen, &c., will 
hereafter be arranged in Table Cases to be made for their recep¬ 
tion. 
On the lower shelves of the Cases 3, 4, and 5, is placed a very ex¬ 
tensive series of cut and polished specimens of fossil wood, most of them 
from the red sandstone formation of Chemnitz in Saxony, and New 
Pa^a in Bohemia, and many of them described and figured in Cotta’s 
work : Die Dendrolithen, Dresden , 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 Coniferse ; in the vicinity of which natural orders 
they are respectively placed in tne Wall Cases. 
The slabs of sandstone on the north wall of this Room, with the 
tracks of an unknown animal called Chirotherium, are, that on the 
lett. from the quarries of Hildburghausen in Saxony; and that in the 
centre, from those of Storton Hill, near Liverpool (the latter pre¬ 
sented by J. Tomkinson, Esq.). On the right hand are placed slabs 
from the same new red sandstone formation, with equally remarkable 
imprests of various dimensions, called Ornithichnites, being very like 
foot-marks of birds: they occur in the sandstone beds near Greenfield, 
Massachusetts, at a cataract in the Connecticut River known by the 
name of Turner’s Falls. 
In this room are also placed two geological models, by the late 
Mr. Elias Hull; one representing part of the High Peak of Derby-
