LOWER CHALK—HAMLSRIR It 
63 
“ Another small pit about 10 feet above the last has yielded a 
specimen of Actinocamax plenus. 
“ A well sunk by the roadside between Bar End and Chilcombe 
reached lower beds consisting of blue-grey chalk which yielded 
Rhynchonella mantelliana, Plicatula pectinoidcs, Lima glohosa, and 
other fossils. More recently a well has been sunk at a cottage close 
to the quarry at Chilcombe, going to a depth of 170 feet, and thus, 
without doubt, reaching the zone of Am. varians.” 
The Kingsclere Inlier. 
The Lower Chalk forms a band of varying width round the Sel- 
bornian outcrop of this inlier, and a good section of the central and 
upper beds is exposed in the railway cutting south of Burghclere. 
I am informed by Mr. F. J. Bennett that this shows marly chalk 
at the northern end, above which comes a bed of grey shelly chalk 
much resembling the Totternhoe Stone, and above this some thick¬ 
ness of greyish blocky chalk. The following fossils were obtained 
from the beds by Mr. Rhodes : —
