UPPER PORTION OF DUNDRY HILL. 191 



had not the slightest connection with the Cephalopod-bed of 

 Gloucestershire, thus correcting some earlier authors. 



W. W. Stoddart^ compared Dundry Hill to an island, pre- 

 sumably in the Jurassic sea ! He gives a diagrammatic 

 section of the strata of the whole hill in the forefront of his 

 paper. He notes that Middle Lias is present ; but the 

 evidence quoted entirely destroys the value of the assertion. 

 " A bluish marly limestone about a foot in thickness and 

 corresponding to the marlstone. ... so full of the 

 shells of Am. thouarseiisis, A. radians, and A. aaleusis, that the 

 presence of the Middle Lias is fully justified" (p. 284). 

 There is obviously a mistake here ; these are ammonites of 

 v^diat Oppel called the ' Lias-ooUth Grenzschichteii ' — the Cot- 

 tesvy^old Cephalopod-bed equivalent, — and they have never 

 been found in Middle Lias, 



In general features the section given by Stoddart corre- 

 sponds with that by Mr. Etheridge; but our researches da 

 not confirm the sequence which he describes. 



In 1878 Mr. J. F. Walker'^ compared the brachiopoda of 

 Dundry with those of Dorset and the Cheltenham district, 

 pointing out that certain species were common to Dundry 

 and Dorset, and were not found in the Cheltenham district, 

 which has its own peculiar forms. He suggested that a 

 PalfBOzoic barrier might have separated the Dorset and 

 Cheltenham areas. 



In his interesting survey of the Inferior Oolite rocks Mr. 

 W. H. Hudleston^ dismisses the Dundry sections in a few 

 words. He says : ".In the present condition of the available
