1847.J PRESTWICM ON THE LONDON CLAY. 367 



Of these the Cyprina planata^ Ostrea jlahellula^ Panopcea interme- 

 dia, Pyrula tricostata, Venericardia Suessonensis, Teredo antenauta 

 and Ditrupa plana, are common at White-Chff, and comparatively 

 scarce at Alum Bay, where however all the other species are far more 

 abimdant. From the latter place I have also several midescribed 

 species of Pleurotoma and Corhula. Of other organic remains we 

 have the Cancer Leachii, teeth of Lamnce, and carbonized wood fre- 

 quently pierced by the Teredo. 



Our next point is the artesian well on Southampton Common^; 

 whence also the series is from beds as fully developed as those of the 

 Isle of Wight. 



The following is a list, chiefly from specimens in the collection of 

 Mr. R. Keele of Southampton, who has had the kindness to give me 

 the free use of all his Southampton fossils. 



Fossils from the Bognor beds at the Artesian well, Southampton"^. 



Anomia lineata, Sow. Pectunculus decussatus, Sow. 



Cancellaria laeviuscula, Sow. brevirostris, Sow. 



Cardium Plumsteadiense ?, Sow. Pholadomya margaritacea, Sow. 



Cyprina planata, Sow. virgulosa, Sow. 



Cytherea obliqua, Desk. Pinna affinis, Sow. 



suberycinoides, Desk. var. Pleurotoraa rostrata, Sow. 



Ditrupa plana, Sow. two new species. 



Fusus bulbiformis, Lam. Pyrula tricostata, Desk. 



angusticostatus, Mell. Rostellaria Sowerbii, Jfa/i^. 



complanatus, Sow. (a small species resembling the 



tuberosus, Sow. Sowerbii, and occurring also at Cla- 



Koninckii, Nyst. rendon Hill and Cuffell). 



n. sp. : same as one found at High- lucida, Sow. 



gate. Turritella imbricataria, Lam. 



Infundibulum trochiforme, Sow. sulcifera, Lam. 



Natica glaucinoides, Soiv. Typhis muticus, Sow. 



Hantoniensis, Sow. Teredo antenauta, Sow. 



Nautilus (either imperialis or Sowerbii). Venericardia Suessonensis, d'Archiac. 



Ostrea flabellula. Lam. Vermetus Bognoriensis, Sow. 



Panopaea intermedia, Sow. Voluta elevata. Sow. 



The species of Turritella, Panopcea, Pholadomya, Natica, Ostrea 

 and Infundibulum are very common. Carbonized wood occurs abun- 

 dantly. 



Proceeding northward, no opportunity offers of observing the or- 

 ganic remains of these beds until we reach the railway cutting at 

 Clarendon Hill, three miles south of Salisbury, where however a depth 

 of only about 40 feet of the lower beds of the Bognor clays are ex- 

 posed. But in this limited extent we meet with precisely those fossils 

 which are of the most typical species.
