Carboniferous . Limestone. Highly inclined, but with a well-planed top. 



From fallen blocks of conglomerate Moore obtained Pteria con- 

 torta (Portl.), Dimyodon intus-striatus (Emmerich), Orbiculoidea? 

 townshendi (Forbes), and Ostrea firnbriata Moore. Moore was of 

 opiniou that these conglomerates had formed slowly, and the 

 condition of the shells, vertebrate-remains, and pebbles certainly 

 supports this view. 



My record differs little from Moore's. 2 He failed to find Estherice 

 or plant-remains in Bed 4. 3 In some pieces of the rock, however, 

 remains of lycopods are not uncommon, 4 and it is interesting to 

 note that this is the farthest place south at which they have 

 been found up till now (1910). Moore also expressed some 

 doubt as to the white limestones being ' White Lias ' ; but he need 

 not have done so, for they are quite typical. The uppermost 

 stratum of the Langport Beds is noticeably bored and waterworn. 



(B) The Eadstock Area. 



Nowhere in this part of East Somerset are the Rhaetic deposits 

 very thick, and at Upper Vobster all that represents them is an 

 occasional thin stratum, with fish-scales, etc. adhering to the 

 surface of the Carboniferous Limestone. 5 



1 Mr. W. H. Wickes has a similar specimen of ' a pupa-case of a dragon-fly ' 

 from the ' Naiadites Bed' of ' Redland (New Clifton), Bristol.'
