MIDDLE CHALK—HAMPSHIRE.

in the position indicated, the first showing hard white massive 
chalk, which is doubtless Lower Chalk and just below the horizon 
of the Belemnite marl, which marl, with some of the Melbourn 
Rock, may well have been visible on the eastern side of the 
pit. The other quarry at a higher level is in the Terehratulina 
zone. 
The chalk of this zone runs along the slope of the hills north¬ 
west of Alton, and may be seen in two small quarries, one by the 
roadside half a mile north of Alton Church, and in another about 
the same distance north-west of the church, both in soft white chalk 
without flints. 
South of Alton it runs to the west of Chawton and Farringdon, 
and through East Tilstead, and is exposed between the two latter 
places in a pit south of Marylane copse. 
South-west of Selborne the Terehratulina zone occupies a consider¬ 
able area, but near Hawkley it is contracted to a narrow outcrop on 
the slope of a steep escarpment. West of Languish and Ramsdean 
it comes within the influence of the Petersfield anticline, and running 
up the Bor dean Valley is exposed in a quarry south-west of Lower 
Bordean. The upper boundary passes by Drayton north-west of 
East Meon, and thence for a considerable distance down the valley 
which opens westward from Combe near East Meon ; thence it 
returns along the slopes of the hills which run into the range of 
the South Downs.

B. Sections in the Winchester Inlier. 
The inlying tract of Turonian near Winchester is not of large 
extent. It surrounds the small area of Lower Chalk mentioned 
on page 62, and extends also for a short distance on the western 
side of the valley of the Itchen. Dips of 5 or 6 deg. carry it 
rapidly beneath the Upper Chalk to the north and south of the 
anticlinal axis. The existence of this pericline appears to have 
been first indicated by Professor Barrois.* 
Zone of Rhynchonella Cuvieri. 
This zone is well exposed in the large quarry at Chilcombe 
(see p. 62). Mr. Ch. Griffith, of Winchester, informs us that 
the Melbourn Rock, “ nodular and very hard, passes up into hard 
chalk with nodular layers and some marly bands ; many of the 
beds are thick and massive, and break out in large blocks with 
curved surfaces, of a yellowish-grey colour when moist.” 
There is another pit in the same chalk on the Portsmouth Road 
south of Bar End. It is also exposed in the Goods Yard of the 
Great Western Railway. From these exposures the members of 
the Winchester College Natural History College have obtained 
the fossils indicated in the list on p. 394.
