This general section of Garden Cliff was drawn by my friend 

 R. Etheeidge, Esq., E.R.S.E., for Professor Rupert Jones' 

 Monograph on the Fossil Estherise, Palseontographical Society's 

 volume for 1862 ; and I have to thank my friend the Rev. T. 

 Wiltshire, E.G.S., Secretary to the Society, for the loan of 

 the wood-cut, and Mr. Etheeidge for his permission to use it. 



The AvictTLA Contorta Beds in Glottcestershiee. 



In the Severn valley the Avicula contorta series has a similar 

 deyelopment in several well known exposures, as at Coombe 

 HiU, Wainlode Cliff, Garden Cliff, Aust Cliff, Penarth Cliff, 

 on the banks of the Severn, and in several other localities in 

 Somerset and Dorset. Garden Cliff, near Westbury-on-Severn, 

 forms the best type of the whole. The following section, made 

 by me many years ago, gives the details of the Lithology and 

 Palseontology of this most beautiful river section.
