ACKNOWLEDGEMENTS. I thank Professor C.H. Holland and Dr George 
Sevastopulo who supervised the Ph.D. study of which this formed a part. This 
paper benefitted considerably from a review by Dr F.K. McKinney for which 
I thank him. I am grateful for the advice of Drs A.J. Bancroft, P.D. Taylor, I.P. 
Morozova, F.K. McKinney, C.J. Buttler, and all the other bryozoologists who 
sent me copies of their work. A.J. Bancroft is thanked for permission to 
examine and figure some of his material from the Upper Carboniferous of 
Yorkshire. Mr Bill Baird (National Museums of Scotland), Mr Gaynor Boon 
(Sheffield City Museum), Mr Philip Doughty, Mr John Wilson and Dr 
Andrew Jeram (Ulster Museum), Mr Stephen Howe and Mr Tom Sharpe 
(National Museum of Wales), Dr H.C. Ivimey Cook (formerly of the British 
Geological Survey), Mr Nigel Monaghan (National Museum of Ireland), Dr 
John Nudds (Manchester Museum), the late Dr David Price (Sedgwick 
Museum), Dr Ian Rolfe and Dr Neil Clark (Hunterian Museum), Dr Paul 
Taylor (Natural History Museum, London) and Dr Nigel Trewin (Aberdeen 
University) all kindly lent material in their care. I am grateful for the help of 
Mr Jeremy Smith and Dr Phillip Tubbs of the I.C.Z.N. and the late Professor 
David Webb (TCD) in answering some of my nomenclatural questions. I 
thank Garry and Bassia Bannister of Dublin who translated some Russian and 
Ukrainian texts for me at very short notice and in a very short time, also Ide 
nf Thuama (Royal Irish Academy) and Dr John Moore who located some 
Soviet and Australian papers for me. This work was carried out while in 
receipt of grants from Trinity Trust (Dublin) and the Irish Geological Asso- 
ciation which are gratefully acknowledged. I am particularly grateful to Paul 
Taylor for his long-standing encouragement, and I thank my wife Vanessa and 
my family, especially my brother Michael, for their tolerance and support.
