PALMOZOIC DISTRICTS OF WEST SOMERSET. 547 
The Cannington-Park limestone we should unquestionably con- 
sider Carboniferous Limestone *. The South-Devon limestones most 
resembling it are the great mass north of Dainton Tunnel, traversed 
by the Great Western Railway, the Connator-Hill limestone adjoin- 
ing the Totnes and Newton turnpike road, as well as that of Barton, 
near Torquay. ‘These are all light-coloured, partially dolomitized 
(the first two scarcely fossiliferous), and with bedding undistinguish- 
able; hence their resemblance cannot be called intimate. 
The bedded and usually dark-coloured limestones at Daddyhole 
Plain, near Torquay, at West Ogwell and Bradley, at Dartington, 
and other localities too numerous to mention, have, neither in 
fossils nor lithologically, the slightest resemblance to the Cannington 
rock; but they have, on the contrary, a decided similarity, which 
amounts at times to identity, to the limestones of Asholt. 
On recrossing the Quantocks to Bishops-Lydeard, we observed on 
Asholt Common a quarry of uneven dark bluish-grey limestone, 
often shelvy, of a character met with so constantly in South 
Devon. This seems to overlie red-brown grits, dipping 8. 20° EH. 
at from 40° to 60° on the north of Asholt Common. Behind Lower- 
Asholt schoolhouse the character of the Devonian limestone de- 
veloped in a horseshoe form, with Merridge as the centre of the 
curve, is shown at its western extremity to consist of reddish and 
bluish ‘ shelvy’ limestone, full of calcite, and intersected by a small 
fault. These we agree with previous writers (especially Sir H. 
De la Beche and Mr. Etheridge) in referring to the Ilfracombo 
series, of which the southern part of the Quantocks appears 
to consist. 
Another very strong reason for the identification of the Can- 
nington-Park limestone with the Carboniferous Limestone of the 
Mendips, of which we think it forms the southern margin (the con- 
nexion being concealed by intervening Secondary rocks), is the 
entire absence of shaly structure or associated detrital matter, 
which are so often characteristic features in the Devonian lime- 
stones. 
In conclusion, we have to express our thanks to Mr. Hall for 
the kind assistance he has rendered in the particulars in connexion 
with which his name has been associated in this paper. 
* This view is confirmed by Mr. Tawney in an exhaustive paper on the 
subject (Proc. Brist. Nat. Soe. vol. i. part 3, p. 880), in which he mentions his 
discovery in situ of Lithostrotion irrequlare and crushed shells, perhaps Tere- 
bulata hastata, or possibly Athyris, also a small Productus elegans, or young 
P. punctatus, and part of a stem of Actinocrinus, obtained by Mr. Winwood. He 
coincides in Mr. S. G. Perceval’s opinion that the limestone is undoubtedly 
Upper Carboniferous Limestone, and mentions that gentleman’s determination 
of the fossils presented to the Taunton Museum by Mr. Baker—Lithostrotion 
Martini, L. irregulare, L. aranea, Clisiophyllum turbinatum, Syringopora ramu- 
losa. He also considers that from this identification of its age “ it follows that it 
is totally disconnected with the Quantock series seen a few hundred yards off.” 
In this unqualified opinion we cannot agree, as it is by no means certain that 
the adjaceat Palseozoie inliers belong to the Quantock series. 
Mr. Tawney noticed the anticlinal structure we have described, and says, 
“ The fault spoken of by Sir H. De la Beche must certainly exist.”
