182 LIAS OF ENGLAND AND WALES: 
In the little plantation (where a dip of 5 S.S.E. was recorded 
on the Geological Survey Map) 1 found exposures of grey earthy 
marls with thin layers and nodules of grey and bluish-grey 
limestone, resting on darker grey shaly marls to the depth of about 
4 feet. They yielded no fossils, and from the fact that traces of 
red staining occurred in these marls lower down the stream, the 
evidence favoured their being of Lower Rhaetic age. Moreover 
a little to the east of the track- way between Stairs and Butterley 
Heys, the banks showed a mass of red clay. Although this might 
belong to the Drift, being in that case rearranged Triassic clay, 
yet its presence in connexion with the grey and ted-tinged marls 
before mentioned, favoured the notion of the Rhsetis age of the 
grey marls in the plantation. 
Lower still down the stream (near Aurllem) there was exposed 
from 4 to 6 feet of unmistakeable Lower Lias as follows:

" 1 Band of limestone with Lima gigantea - 2 to 3 
Grey shales in bed of stream, dipping gently 
[ towards the N.W. 
Ammonites ungulatus and Gri/phcea arcuata were found here by 
the Rev. T. W. Norwood of Wrenbury ; and Mr. C. E. De 
Ranee has obtained Area and Ostrea irregularist If we regard 
the beds seen higher up the stream as Rhsetic, there must be a fault 
a little east of the track-way before mentioned. 
North-west of the church at Burley Dam, there is a plantation 
through -which a stream has cut into the Drift, and exposed in its 
banks, and on its bed, hard greenish marls. They are overlaid by 
red and variegated marls, evidently Ketiper, and I could detect no 
traces of Rhsetic Beds where a dip of 8 S.S.E. is marked on the 
Geological Survey Map. 
Evidence has been obtained for extending the Lias further 
westwards, and eastwards probably also, while the boundary taken 
on the north, near Burley Dam, must be brought a little further 
south. Thus the Rev. T. W. Norwood has discovered traces of 
Rhaitic beds and Lower Lias in the banks of the stream, north- 
west of Heakl, between Frith Farm and Wrenbury Wharf. 
He obtained Pleuromya crowcombcio, and shales with Cardium 
rh&ticum. 
A specimen of Ammonites striatus was procured by Mr. Ikin 
from Fauls Green east of Frees. In this case the Lias is perhaps 
faulted against the Keuper Marls, as shown on the Survey Map, 
although the former formation should extend further east to the 
fault. Mr. Ikin also obtained a specimen of Lias rock with 
Gri/phcea obliquata, Lima, and Bclcmnites from the bank of a road- 
cutting near Marchamley, between Marchamley and Hodnet. 
I was tmablc to verify its occurrence in situ ; the block was 
probably procured from the Drift.
