166 Miscellanies. 
Crocodile-—Two, or more, enormous species of this genus of © 
Saurian reptiles, were contemporaries of the Iguanodon. There are 
teeth, vertebre, humeri, chevron bone, ribs, &c. One of the spe- 
cies resembles a fossil crocodile found at Soleure, and described by 
Baron Cuvier. 
Plesiosaurus.—Of this extinct genus, first described by Mr. Cony- 
beare, vertebra, teeth, humeri, and other bones, occur in the strata 
of Tilgate Forest. 
Chelonian Reptiles.*—The bones anil scales of these animals are 
of frequent occurrence in the Hastings beds. They are referable to 
the following :-— 
1. A fresh water species, allied to the Trionyz. 
2. An unknown species of Emys, resembling a fossil fresh water 
turtle found in the Jura limestone. 
_ 3. A marine species, belonging to the subgenus Chelonia, and re- 
lated to the fossil turtle of Maestricht. 
Fishes——Their remains consist of dorsal fins, of great strength, 
and armed with spines, resembling those of the Silurus ;+ teeth of 
various forms, some tricuspid and striated ; others hemispherical, the 
bufonites of the older geologists; and palates of various kinds. "| 
the collection there are two splendid specimens of a fish with lozenge- 
shaped scales ; one showing a pectoral fin ; the other, portion of ” 
opercula of the gills. 
Ve egetable Remon —These are numerous, although belonging to 
but few species. The most remarkable is t 
Clathrariat Lyeilii,§ of which there are specimens of the imter- 
nal and external parts of the stem, in a beautiful state of preserva- 
tion. The original probably attained a considerable height ; it is re 
lated to the Dracena draco, (Dragon-blood plant). Some exam 
ples show traces of the base of the flowers; and the fossil seed-ves- 
sels found in the same strata, are supposed to belong to this plant: 
The other large vegetable of this period is the Endogenttes erosa, of 
which there are many enormous stems: the original was evidently 2 
monocotyledonous plant, bearing an analogy to the Cacti and —_— 
bia. Almost all the specimens are flattened by the compressed 
the strata, when in a softened state.
