428 THE CRETACEOUS ROCKS OE BRITAIN. 
There was no sign of the Belemnite Marls anywhere, nor could 
I find any fossils except the one mentioned. The succession 
recalls that of Crux ton. 
Near Pinnys Toller, or Toller Whelme, as it is called on the new 
Ordnance maps, the whole thickness of the Middle Chalk comes 
out from beneath the capping of clay with flints, and parts of it 
are exposed in old quarries by the main road north of Toller leading 
to Hill Barn. On the right hand side of the road, just above the 
600 feet contour, hard nodular chalk, which resembles weathered 
Melbourn Rock, overlies softer blocky chalk. At about 650 feet 
is a quarry in firm, homogeneous white chalk, with small Rkyn- 
chonella Cuvieri and Terebratulina gracilis var. lata, while just 
at the 700 feet contour are old quarries in Chalk Rock, so that 
here there seems to be nearly 100 feet of Middle Chalk. 
No good exposure of Middle Chalk was found north of Beaminster, 
nor near Cheddington, but the base of the division was seen 
in a quarry near Corscombe (see p. 117). 
Somerset and Devon (inland). 
The outliers of Chalk which occur near Crewkerne and Chard, 
and the others further west between Chardstock and Honiton, 
have been mentioned on p. 117. Several of these tracts are capped 
by still smaller outliers of Middle Chalk. Thus between Crewkerne 
and Chard there is a small tract of this chalk on Lady’s Down, its 
base occurring at a height of about 730 feet; and there is another 
north of Cricket St. Thomas brought in by a fault which has a 
downthrow to the west of 60 or 70 feet. 
South of Chard are two small tracts of Middle Chalk, each of 
them being faulted down on two sides against Lower Chalk, and 
on the hill west of Chard is an outlier about Id mile Ions bv three-

quarters of a mile wide. Near Combe St. Nicholas is a small 
triangular tract of Middle Chalk and Chalk Rock let down into 
the valley far below its normal level between three lines of fault, 
the vertical displacement on its eastern side being over 300 feet. 
On the high ground north-west of Combe there is another area of 
Middle Chalk which probably occupies some space, though it is 
partly "covered by clay with Hints. It caps an outlier of Lower 
Chalk, and also includes a tract of Chalk Rock, the base of which 
runs from 800 to 730 feet above sea level. 
Near Membury, north of Axminster, a powerful fault lets in a 
long narrow tract of Chalk, part of which consists of the Middle 
division. 
Lastly, near Widworthy, east of Honiton, another tract of such 
chalk is brought in by a similar fault, and this consists entirely of 
Middle Chalk resting on the arenaceous representative of the Lower 
Chalk or Cenomanian. 
The chalk seen at the places above mentioned includes repre¬ 
sentatives of the zones of Rhynchonella Cuvieri and Terebratulina-.
