PEOF. J. PRESTWICH ON THE PwAISED 



of Mammoth, with the teeth complete, from Worthing, mentioned hy 

 Mr. Dixon, ^ and the greater part of the Mammoth's skeleton, from 

 Peppering, near Arundel, described by Dr. Mantell, belong to beds 

 of this age. But the largest and best known collection of mamma- 

 lian remains comes from Selsey or Bracklesham. There is, however, 

 a difference of opinion as to the position of this bed. Some geolo- 

 gists have considered it to be of older date than the Brighton Head, 

 although I see no reason for doing so. The sections are certainly 

 obscure, but the remains, with the exception of the' Elephas antiquus 

 (which does not occur at Brighton, though it does at Polkestone), 

 are all of the same ordinary species, namely : — 



Elephas antiquus. 



'primiijenius. 



Bhinoceros tichorhinus. 

 Equus cahallus. 



Bison prtscus. 

 Bos longifrons. 

 Cervus eiaphus, 

 Canis lupus. 



Elsewhere under the rubble, remains of the old Beach are often 

 met with — sometimes with, and at other times without shells. 

 Mr. Dixon records its occurrence at Broadwater and Sompting near 

 Worthing, with Littorina littorea, L. rudis, and Purpura lapillus. 

 At Oving, near Chichester, it contains Tellina halthica, and in the 

 Chichester Museum there are specimens of Cardium edule and My- 

 tilus edulis from the same place. ^ This Beach attains its highest 

 level of 130 feet above O.D. at Waterbeach, near Chichester, 7 miles 

 inland. To the shells already recorded I may add Nassa incy^assata. 

 Under the gravelly clay on the coast near Pagham, a thin bed with 

 Littorina, Cardium, and Mytilus is occasionally met with, and frag- 

 ments of the same have sometimes become incorporated in the 

 overlying drift. An ear-bone of a whale was fouud at Bracklesham. 



Over the plain between Worthing and Pagham, in addition to the 

 pebbles of foreign rocks commonly found as far as Brighton, large 

 boulders of similar rocks are met with in considerable numbers. 

 Near Barnham Parm, there was a few years ago a block of line- 

 grained red granite, measuring 2| feet by 1| foot. Occasional blocks 

 occur in the direction of Chichester. At Waterbeach I found small 

 boulders of chalk, but none of foreign rocks, in the sand of the old 

 sea-bed. But it is at and around Pagham Harbour that the foreign 

 boulders are found in greatest number and of largest size. Godwin- 

 Austen mentions ^ : — 



G-rey porphyritic Granites. 



Compact red Granites. 



Syenite. 



Horublendic Greenstone. 



Mica-sehist. 



Green fissile slates, and 



Fibrous chloritic semicrystalline rocks. 



Masses of Vein-quartz. 



Siliceous Sandstones. 



Conglomerates. 



Micaceous Sandstones with OrthidoB. 



Black micaceous shaly Sandstones. 



Compact Limestones.

^ This bed is distinct from the remarkable shell-bed with its large Bholades 

 at Bracklesham, to which I purposely omit reference owing to the uncertainty 

 of the sections hitherto given.
