The followimg observations may be useful to the collector in marking 
the localities in which some of the rarer organic remains are procured. 
The deposit of Eocene fossils lying to the south-east of Selsey, I 
shall term the ‘ Park-bed,’ as it is part of the shore which still retains 
the name of Park Coppice. It is rather more than a mile to the left 
of Selsey Bill, and its length is half a mile towards Pagham Harbour. 
The Park-bed developes to a great extent the formation called ‘ Calcaire 
grossier*’; it contains myriads of the Nummularia levigata, with other 
shells interspersed, such as Pecten corneus, Bulla Edwardsii, Cyprea in- 
flata, Solenes, Arce, &c., Astrea Websteri and several corals. This may 
be considered one of the best spots for the collector; the shells are 
also in good preservation. Adjoining this bed to the east, we perceive 
a greenish sand and clay deposit, containing Tellina scalaroides and 
Tellina tenuistria, but it is difficult to get these shells perfect ; and we 
also find rolled fragments, somewhat similar in their composition to the 
Bognor rock, but containing Nummulites and a greater proportion of 
lime; on breaking these, good casts of rare fossils may be found, 
sharks’ teeth, &c. On one occasion I obtained a good specimen of the 
Myliobates. Ihave picked up also on the shore crocodiles’ teeth, and 
several specimens of the Myliobates, A:tobates and Edaphodon. Further 
eastward we recognise three distinct patches of arenaceous limestone, 
of a greenish blue colour, divided into different-sized nodules, some two 
or three feet high, containing Twurritelle, Nucule, &c. Between these 
moth’s existence no division of the land had taken place, as it is common for fishermen to drag up 
in all parts of the Channel unrolled specimens of the tusks, bones and teeth of that animal. But 
we have still a further right to suppose, that the division called the English Channel is of a much 
more modern date, and was caused by some great irruption during the Post-Pliocene period ; for 
the same living animals exist common to both countries, or did exist since the historical period 
—wolf, goat, moles, shrews, water-rats, &c., which could not have been all imported. 
* From the calcaire grossier bed in the neighbourhood of Grignon, four hundred distinct spe- 
cies of shells have been procured.
