96 LIAS Or ENGLAND AND WALES: 
shown. The beds may possibly be faulted with a downthrow on 
the west. 
Proceeding towards Watche!, we lose the cliffs for a short 
space, and pass along a beach formed largely of Lias stones, which 
are collected here and at St. Audries, and conveyed by donkeys to 
Donniford kiln. On the foreshore Ammonites Turncri occurs 
in shaly limestone, and in the low cliffs succeeding, we find shah- 
marls with thick beds of argillaceous limestone (belonging to 
Division 5). These beds are capped by gravel, which toward.- 
the enst forms the whole of the low cliff, giving it a reddish-brown 
appearance. The stones are chiefly Devonian, Lias being rare if 
not absent. 
Continuing towards the Bathing Cove, we find shaly marls and 
paper-shales much jointed, with occasional thick bands of lime- 
stone, exposed in the cliffs and on the foreshore, but faulted in 
places. Large Ammonites suggestive of A. stellaris occur., but 
in the cliffs at the Bathing Cove, apparently on a higher horizon, 
we find A. Tnrncri in beds of grey marl and shale with occasional 
limestone, shown to a thickness of 25 feet. These beds are faulted 
to the north against grey limestones and shaly marls with 
Gryphcea arcuata, strata which are themselves faulted again 
further north against the Keuper Marls. Whether in this 
district there are any marly and clayey beds above the zone of 
Ammonites semicostatus is not clear, for the beds are so 
repeatedly faulted ; further paloeontological evidence is much to be 
desired. 
West of Watchet the Lower Lias limestones with Ammonites 
Bucldandi, have been quarried near Saxon House, and here the 
beds incline seawards, being however faulted against the Red 
Marls, &e. which form, for the time being, A. protecting face of 
cliff. As soon as the IVd Marls are denuded the Lias will 
rapidly break away. Between Watchet and Blue Anchor the 
beds are again much faulted and disturbed. 
About midway there is a gap in the cliffs, on either side of 
which the Lower Lias is exposed. On the eastern (side we find 
division ] : thin fissile shaly limestones breaking up into rhom- 
boidal masses by jointing. Here the stone from the beach is 
hauled up an inclined plane to a lime-kiln. Iridescent Ammonites 
occur here, including A. planorbis and A. Johnstoni. Dr. 
Wright has observed that th >se shales yielded the original 
specimens of Ammonites planorbis and A. Johnstoni, figured by 
Sowerby in his " Mineral Uonchology." The nacreous layer of 
the shells is beautifully preserv -I." 
On the west side of this gap we pass a small mass of the lower 
Rhsetic beds and Keuper Marls, faulted against Lower Lias. 
These beds consist of alternations of grey earthy limestone and 
shale, and here some plant-r< mains were obtained from the Lias 
by Mr. S. G. Perceval. The beds are much slipped and probably
