286 PROF. J. PRESTATICH ON THE llAISED 



. There are no Raised Beaches between Ilfraconibe and Lynton, 

 hut in places there is an accumulation of local rubble or Head. At 

 Porlock Bay, where it has been described by Godwin- Austen, the 

 Head extends for some distance out to sea and forms the substratum 

 on which the Submarine Eorest grew. This therefore fixes a limit 

 to the age of the Submarine Forests on this coast. 

 ' (17) The Somersetshire Coast. — The principal Raised Beach on 

 this coast is that at Weston-super-Mare, and .though, owing to 

 the lowness of the land between Bridgwater and AVeston, the sea 

 would ssem at one time to have extended inland to the foot of the 

 Mendips, no traces of the Beach are recorded on the surrounding 

 hill-slopes. Within this area, however, as at Chilton Trinity, near 

 Bridgwater, there are several banks of shingle, which may have 

 been shallows in the sea-bed of the period ; and Mr. H. B. Wood- 

 ward records the occurrence of marine shells at Middlezoy and Sutton 

 Door, near Glastonbury.^ 



The section wliich I saw at Chilton Trinity was only 7 feet deep 

 and exposed : — 



feet 



1. Brown loam and a little gravel 2^ 



2. Concreted sand, forming thin tabular slabs 0^ 



3. Shingle of quartz, quart zite, flints (subangular and stained 



— irom an older gravel), and other pebbles in a matrix 

 of sand with numerous entire shells (chiefly Mytilas 

 edulis and Cardium edule) 4 



Mr. W. Baker, of Bridgwater, made a collection of these shells, 

 of which a list will be found on p. 300 of thu present i>aper. 



The limestone promontory of Anchor Head Hill, just north of 

 Weston-super-Mare, terminates in a double cliff — the lower one 

 due to present sea-action, while the other, which stands above it 

 and a few feet back, is of the date of the liaised Beacli. At the 

 foot of the upper cliff were the remains of a concreted beach about 

 25 feet above the i)resent shore. But it has, since I first saw it, in 

 great part been quarried away in making new roads and terraces. 

 The only shells I obtained were Tellina balthiea, Littorina littorea, 

 L. 7-udis. Patella vuhjata, and Trophoa (?). 



Mr. E. C. H. Day ^ mentions that he found bones and teeth of a 

 small species of Horse, and one tooth of Ilyf.eiia spekm and of 

 Cants vulpes respectively, in i he concreted Beach ; as this was in a 

 block that had fallen down on the ])resent shore, it may be doubtful 

 whether it was not a portion of the Head, which is also partly 

 concreted. I found no bones. 



At Woodspring Hill, two miles north of Weston, there are the 

 remains of another Beach, 20 to yO feet above high-water, in which 

 Tellina halthica, Littoriyia littorea, L. rudis, Patella vidc/ata, Mare.v, 

 Nassa, Purpura, Cardium, and Ostrea have been found. ^
