Yarmouth, as described by Mr. Edwards. The Bulimus ellipticus, fig. 213, 

 and Helix occlusa, fig. 214, are among its best known land-shells. Paludina 

 orbicularis, fig. 215, is also of frequent occurrence. One of the bands is 

 filled with a little globular Paludina. Among the freshwater pulmonifera, 

 Lymnca longiscata (fig. 21*7) and Planorbis discus (fig. 216) are the most gen- 

 erally distributed : the latter represents or takes the place of the Planorbis 

 euomphalus (see fig. 221), of the more ancient Headon series. Chara tuber- 

 culata (fig. 218) is the characteristic Bembridge gyrogonite.

From this formation on the shores of Whitecliff Bay, Dr. Mantell 

 obtained a fine specimen of a fan palm, Flabellaria Lamanonis, 

 Brong., a plant first obtained from beds of corresponding age in the 

 suburbs of Paris. The well-known building-stone of Binstead, near 

 Ryde, a limestone with numerous hollows caused by Cyrence which 

 have disappeared and left the moulds of their shells, belongs to this 

 subdivision of the Bembridge series. In the same Binstead stone Mr. 

 Pratt and the Rev. Darwin Fox first discovered 

 the remains of mammalia characteristic of the 

 gypseous series of Paris, as Paleotherium mag- 

 num (fig. 220), P. medium , P. minus, P. mimi- 

 mum, P. curium, P. crassum ; also Anoplo- 

 therium commune (fig. 219), A. secundarium, 

 Dichobune cervinum, and Chceropotamus Cu- 

 vieri. The genus Paleothere, above alluded to, 

 resembled the living tapir in the form of the 

 head, and in having a short proboscis, but its 

 molar teeth were more like those of the rhi- 

 noceros. Paleotherium magnum was of the 



size of a horse, three or four feet high. The annexed woodcut, fig. 

 220, is one of the restorations which Cuvier attempted of the outline
