LOWER LIAS : RADSTOCK. 129 
The layers of Corn grit are used for paving ; the limestones above are said 
to make the best lime in the district. Ta%vney obtained a specimen of Ammonites 
planorbis at this quarry, probably from the lower beds. 
The Lower Lias was well exposed in cuttings alon the 
Midland Railway between Radstock and Wellow. South-east of 
Shoscomb the Sun bed was seen at the base of the Lias. The 
limestones of the Lower Lias, which are rather disturbed in 
places, are rich in fossils. The Spirifer-bank, as was pointed out 
to me by Moore, occurs in the upper part of the Limestone Series 
capped by blue clay, which is the Foraminifera-zone. Towards 
Wellow, cuttings in blue clay have been made, and this is apparently 
unfossiliferous. Bands of earthy limestone occur here and there 
in the clay, which is micaceous, and in part of Middle Lias age. 
Upper Lias was identified in places by Moore, and the beds are 
capped by Inferior Oolite. 
At Stoney Littleton the following section was to be seen : 
FT. IN. 
"Clay, with Spiriferina Walcotti and S. rostrata, 
Rhynchonella variabilis, Belemnites, Ammonites 
Maugenesti, A. raricostatus, A. semicostatus ? 
Fossils in many cases phosphatized 1 
T , Thick limestone, with many specimens of Gryph&a 
j ^ arcuata at top. Amm. Bucklandi - 2 
Rubbly limestone and clay. Lama gigantea, Ostrea 5 
Stone with clay-partings. L. gigantea - -70 
Thinner beds of limestone and brown shale (Corn 
L grit) - .... 2 
>- White Lias (ferruginous stains on joints). 
I also obtained Lima hettangiensis, L. succincta, Pholadomya 
glabra, and Unicardium cardioides. 
Near Stoney Littleton large blocks of sandy iron-shot limestone 
were found imbedded in the blue clay at the base of the railway- 
cutting. They yielded Pecten lunularis (liasinus}, Ammonites 
Ibex, A. Maugenesti, and numerous Belemnites: thus indicating 
the zone of Am. Jamesoni. 
Proceeding north of Radstock towards the Clan Down coal- 
works, there are several quarries, which however are not much 
worked at present, and it is difficult to note the sequence of the 
beds down to the White Lias. The sections have been recorded 
in detail by Tawney* and Prof. Tate.f Ammonites Jamesoni. A. 
Henleyi, and other species occur in the upper beds ; lower down 
A. subplanicosta has been met with. I obtained Ammonites Ibex, 
A. Maugenesti.. A. raricostatus, A. semicostatus, A. Valdani, 
Pleurotomaria, Gryplma, Lima Hermanni, Pholadomya ambigua, 
Rhynchonella rariabilis, Spiriferina Walcotti, and Terebratula 
punctata: species iudentified by Messrs, Sharman and Newton. 
Further on at Bowldish, a quarry north of Welton, and imme- 
diately south-west of the cross-roads between Clan Down and 
Paulton, showed the following section, which I visited in company 
with the Rev. H. H. Winwood :
