468 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



year an admirable section has been opened on the Taunton and Chard 

 Railway at Hatch, which is on the edge of the same escarpment, 

 but about two miles distant from Beer, in which the Keuper, Rhaetic, 

 and Liassic beds are again continuous. 



On proceeding hy road from Taunton to Hatch, the Keuper Sand- 

 stones are exposed about midway at Ruishton, and have yielded teeth 

 of Labyrintlioclon, serrated teeth of Belodon ?, Acrodus Kewperinus, 

 &c., with. EstJieria miniUa in the more indurated marls. These beds 

 are no doubt the equivalents of those yielding the same remains in 

 Worcestershire and elsewhere.

The above beds in their passage towards Hatch were seen, in 

 shafts sunk on the line of railway, to be subordinate to gypseous 

 marls, which were observed passing under the Rhsetic and Liassic 

 escarpment to the south-east. At Watchet, Aust, and Penarth, the 

 Rhaetic beds are seen to lie almost immediately upon these gypseous 

 marls ; but at Hatch there are clearly interposed a series of beds not 

 only more varied in their general lithological character, but more 

 regularly stratified than are the higher members of the Keuper gene- 

 rally. Although it may be suspected, it is very difficult to prove 

 unconformability with these beds, owing to the almost entire absence 

 of organisms through a great part of the series, and the similar litho- 

 logical character they present. If we may assume that the gypseous 

 beds at the bottom at Hatch, and those at the above places, are on 

 the same horizon (which, from their mineralogical character, seems 

 very probable), the beds which succeed in the Hatch cutting would 

 be absent, and the Rhaetic beds in those places would be uncon- 

 formable.
