SILURIAN FOSSILS FROM LOCALITIES IN TORTWORTH. 
35 
Llandovery horizon between the two trap bands has yielded fossils. 
The first exposure to which we wish to refer is one by a little pond a 
short distance N.W. of Pool Farm, where from calcareous Llandovery 
sandstone the following species of fossils were obtained : — Palceocyclus 
sp., Atrypa reticularis^ Rhynchonella serrata, Strophomena sp., a 
gastropod and crinoid stems. 
The main part of this exposure dips at 15° S.S.W., but part dips 
W. 20° S. at a high angle. 
Abundant Llandovery debris was found at several points in the 
fields between Pool Farm and Charfield Mills. 
Debris from the field immediately to the north of Pool Farm con- 
tained the following fossils : — 
Lindstrcemia suhduplicata 
Rhynchonella serrata 
Coelospira hemispherica 
Atrypa reticularis 
Tentaculites anglicus 
Encrinurus punctatus 
The following fossils were obtained in calcareous sandstone of the 
usual type in an old greatly overgrown quarry about 150 yards E.N.E. 
of Charfield Station : — 
Ccelospira hemispherica 
Rhynchonella nucula 
Atrypa reticularis 
hhtrophomena ? arenaceoj 
Chonetes striatella var. 
Strophonella euglypha ? 
Spirifer elevatus 
,, crispus 
Holopella sp. 
Tentaculites sp. 
Phacops toeaveri 
Lindstroemia ? sp, 
Inspection of the map of Buckland and Conybeare shows this to be 
probably Long’s quarry, from which Phacops weaveri and Coelospira 
hemispherica in the Jermyn Street collection were obtained. Weaver^ 
mentions the occurrence of strontian sulphate in Long’s quarry. 
Abundant debris in the cultivated field in front of the cottages to 
the south contained : — 
Strophomena compressa 
Ccelospira hemispherica 
Chonetes striatella ? 
Orthis elegantula ? 
A try pa reticularis 
Rhynchonella nucida 
Goniophora cymhceformis 
Pleurotomaria sp. 
Tentacxdites anglicus 
Phacops weaveri 
Encrinurus punctatus 
Crinoid stems 
Lindstroemia sp. 
The following fossils in Lord Ducie’s collection from Charfield rail- 
way cutting probably came from a point not very far removed from 
this spot : — 
Strophomena ? arenacea 
Encrinurus punctatus 
Phacops weaveri 
? Murchisonia sp. 
Gomphoceras sp. 
Trochoceras sp.

Note. — Long’s, Culliinore’s, Ponting’s, Barber’s, and Horsley quarries are 
referred to under these names in Buckland’s and Conybeare’s paper. 
These quarries have all been abandoned for many years, and are 
not now known by these names.
