In conclusion I wish to express my gratitude to all who have 

 helped me in my work. 



I especially wish to thank Prof. Watts for his valuable advice 

 as regards the working of the north of the Long Mountain, and 

 for the loan of specimens collected by himself in that locality ; 

 and Mr. Lake for kindly directing me to the most promising 

 sections in the Llangollen Basin. 



I should like also to thank Prof. Hughes for allowing me to 

 make free use of the collections in the Woodwardian Museum ; 

 and Prof. Lapworth and Mr. Marr for the kind interest and help 

 which they have given me at all times. 



Last, but not least, my thanks are due to my friend and colleague 

 Miss E. M. R. Wood, in whose company many sections at the 

 junction of the Wenlocks with the Ludlows were worked, and to
