was, -when I saw it, very obscure; whether above or below the 

 Nummulina varloTaria bed, I could not satisfy myself. The dip of 

 the strata would appear to make it the Cypra^a-bed of Dixon {d, 

 below) ; but its lithological character is difFerent. I will give the 

 sequence of the beds round Selsey Bill as I observed them, merely as 

 a guide to those who may visit the spot. 



Commencing at a spit of gravel seen at low water, brought 

 together by the meeting of the tides from the Park and Bracklesham 

 Bay, and going westward, we have this apparently ascending sec- 

 tion : — 



Paces. 



Beds covered with sea-sand 600 



Outcrop of septaria, resting on sandy clay, weathered green, with 

 remains of shells ; just seen. 



Beds covered with sea-sand 127 



Hard, dark-grey, sandy bed, Nummulitic in the upper part. Num- 



mulites abundant at 216 paces. Concretions at 226 paces 420 



Nummulites and other Foraminifera in clay 324 



The Nummulite of these beds is Nummulina variolaria. 



Taking up the last-named bed again, as being the highest cer- 

 tainly distinguishable at this place, we have the general descending 

 series along nearly 3 miles of the shore as follows : — 



Descending Series at Bracklesham Bay *. 



Paces. 

 ^22 (5) Clay, weathered grey, crowded with Nummulina va7'iolaria, 

 Alveolina sabulosa, Quinqtceloculina Hauerina, Biloculina 

 ringens, Botalia obscura, Turhinolia sulcata, &c. ("Clibs") 324 



Beds covered with sea-sand 185 



21 (c) Hard calcareous sand, with comminuted shelly matter and 

 numerous TellincB and other fossils ("Hard Bed"t). 

 Many of the Foraminifera of No. 22 are common in 



this bed 140 



Concretionary lumps at the bottom of the above 105 



. ,20 Greyish clay, with Corhulce and NummulincB dit 38 paces ... 120 

 ■ 19 (c?) The clay becomes darker and more sandy, and fossils increase 

 in number. They are most abundant towards the middle 



of the bed (Cyprcea-bed of Dixon) 460 



18 Sandy clay, firmer than the last, containing many of the 

 same shells, but not so abundantly ; seldom seen : it was 



exposed in Aug. 1857 66 



17 Sandy clay, weathered green (Pleistocene weathering J); 



remains of fossils in the upper part 194 



Pleistocene mud 112 



Green sandy clay 300 



* This list of beds was made in May 1861. The beds were then, on the 

 whole, very favourably exposed ; but occasions sometimes occur when they are 

 still better seen. I saw them better than I have ever seen them before or since, 

 in June 1856. 



The fossils of the different beds of Bracklesham Bay, and of the other most 

 celebrated localities, will be given in a catalogue which is in preparation. 



t The local names are those used by W. Woodland, of Medmery Farm, who 

 collects for sale. 



\ Not the least interesting phenomena at Bracklesham Bay are those con- 

 nected with the Pleistocene beds. The greater part of that area has been 

 occupied with forest-ground ; and during the period that it was dry land the 

 Eocene beds formed the subsoil, and that weathering took place which is so fre-
