Band 3 in the above section, which is full of Pecten vagans 
and P. lens, is very prominent. Its westernmost outcrop is due 
south of Townleaze Barn. 
Ata point nearly half a mile west of Bradfield Farm, the Cornbrash 
is seen coming on above the Forest Marble, and an excellent section 
of it is exposed in the cutting as far as the farm, as well asin a 
road-cutting leading te Hullavington Station. 
The cutting west of Bradfield Farm shows the following section 
of Cornbrash :—

Fossils are, as usual, very plentiful in the Cornbrash ; we ob- 
tained :— 
Echinobrissus clunicularis, Llwyd.; Waldheimia (Ornithella) odovata, Sow. 
(Very common.) _ Lehynchonella concinna, Sow.

The westernmost outcrop of the Middle Oolites is near Kingway 
Barn, whence they extend as far as the end of the line at Wootton 
Bassett, a distance of some 10 miles. By far the greater part of 
this distance 1s occupied by the Oxford Clay, the Conalben being 
seen only in Wootton Bassett station-yard. Unfortunately our 
examination of these beds was delayed till they were very much 
earthed-in and overgrown. 
The Callovian is seen ina cutting which traverses the northern 
end of Bincombe Wood, between Rodbourne and Kingway Barn.
