' Etheridge,' he wrote, ' originally placed them [that is, the ' Tea- 

 Green Marls'] in the Kenper, and distinguished them from the 

 Grey Marls which frequently form the base of the Phytic' 1 In 

 support of this interpretation of Etheridge's remarks, Mr. Wood- 

 ward quoted from the paper published by Etheridge in the 

 Proceedings of the Cotteswold Naturalists' Field-Club. In that 

 paper, Etheridge recorded this sequence: — 'alternating bands of 

 grey and red fissile and conchoidal marls (No. 1 in section), 

 apparently here containing no fossils'; 2 and then, above these 

 'Tea-Green Marls' a series of Grey Marls. The point upon 

 which Mr. Woodward naturally laid stress was that Etheridge 

 denominated the lower of these two series the 'Tea-Green 

 Marls': not the upper, which he distinguished by the name 

 of ' Grey Marls.' As will be seen by referring to his section 

 at Garden Cliff, the beds that he wished to be called the ' Tea- 

 Green Marls ' are not those to which the term has been restricted 

 by most authors. Etheridge's suggestion with regard to these 

 ' Tea-Green Marls ' of his at Garden Cliff was, that although 

 they did differ lithically, they nevertheless corresponded to 

 certain beds at Watchet, Penarth, and Puriton, 



'at which places,' he wrote, 'I have termed them "Tea-Green Marls," from 

 the peculiar hue of the freshly-fractured shales when exposed, and the con- 

 stancy of their conditions.' 



The ' Grey Marls ' (the upper strata of which are here designated 

 the Sully Beds) above he regarded as belonging to the Phytic, 

 because they contained fish-remains. 



Mr. Woodward's explanation of Etheridge's conclusions is very 

 satisfactory, because I had been compelled to adopt the view that 

 there were marls which were Rhastic, and again such as were 

 Keuper. But, while agreeing with Etheridge that this was the case, 

 I fail to see any evidence, either palseontological or stratigraphical, 

 why the marls below what I have called the ' Tea-Green Marls ' at 

 Garden Cliff (which there come immediately below the Etetic 

 Black Shales) 3 should be regarded as the equivalent of certain beds 

 which Etheridge admitted were lithically different at Penarth, 

 Watchet, and Puriton. Is it not much more probable that the ' Grey 

 Marls ' — certainly that the fossiliferous portion of them, namely, 

 the Sully Beds — of the Lavernock and Watchet districts — are not 

 represented in North-West Gloucestershire and Worcestershire ; 

 and that they are only found within the limits of those 

 areas which were submerged at the time when the 

 Rheetic ocean gained access to the British low-lying 

 country ? 



These Sully Beds will be again dealt with after the sections in 

 Glamorganshire have been described.
