134 PKOCEEDINGS OF THE GEOLOCHCAL SOCIETY. [June 23, 



surface of the ground slopes down to the River Stour. Gravel caps 

 the hill ; and the Lower Tertiary sands are seen in a section, at its foot, 

 near the railway-station, and also at a farm about half a mile to 

 the east. 



Grove Ferry 

 N.W. Up street. Sandpit. Railway-station. S.B. 



a. Grravel. h. Thanet Sands. 



The fossil shells which I found in the little sand-pit were mostly 

 very fragile, but in considerable abundance. They occurred both in 

 sand and in dark red clay § ; and some were nearly white, whilst others 

 were tinted rusty red. Those which belong to Crag species appeared 

 especially to be of a reddish colour. 



The beds forming the central portion of this hill above Grove Ferry 

 would appear, according to Mr. Prestwich's sections^ of the Lower 

 Tertiaries of that neighbourhood, to belong to the "Basement-bed of 

 the London Clay," overlying " Woolwich beds" and " Thanet Sands ;" 

 but many of the fossils which I collected here in 1854, and at sub- 

 sequent visits, appear to have an Upper Tertiary character ; indeed 

 some cannot be distinguished from Crag species. Others, on the 

 contrary, resemble forms belonging to the Middle and Lower Tertiary 

 deposits. 



The following list of the species collected by me in 1854-57 has 

 been drawn up by Mr. George B. Sowerby. 



Fossils from Up Street near Chislet. 



The New Species are marked thus ^ ; the Crag species, t ; the Lower Tertiary 

 species, | ; and the Belgian Tertiary species, || .
