Crocodile. — Two, or more, enormous species of this genus of 

 Saurian reptiles, were contemporaries of the Iguanodon. There are 

 teeth, vertebras, humeri, chevron bone, ribs, Sic. 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, vertebrae, teeth, humeri, and other bones, occur in the strata 

 of Tilgate Forest. 



Chelonian Reptiles.* — The bones and 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 Trionyx. 



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. In 

 the collection there are two splendid specimens of a fish with lozenge- 

 shaped scales ; one showing a pectoral fin ; the other, portions of the 

 opercula of the gills. 



Vegetable Remains. — These are numerous, although belonging to 

 but few species. The most remarkable is the 



Clathraria\ Lyellii,'^ of which there are specimens of the inter- 

 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 Draccena 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 Endogenites erosa, of 

 which there are many enormous stems : the original was evidently a 

 monocotyledonous plant, bearing an analogy to the Cacti and Euphor- 

 bia. Almost all the specimens are flattened by the compression of 

 the strata, when in a softened state. 



* Tortoises and turtles. 



t The Silurus is a fish that inhabits the rivers of Europe and the East, and is the 

 largest of fresh water fishes.
