In no part of England has the fish-fauna of the Coal Measures been more sedulously 

 collected and accurately determined than in North Staffordshire. The splendid collec- 

 tion made there by Mr John Ward, F.G.S., of Longton, and now in the British 

 Museum, is an historical one, with which I have been for nearly thirty years familiar, 

 and to the working out of which I have myself contributed. To Mr Ward personally, 

 and to his work On the Geological Features of the North Staffordshire Coal Fields, I 

 am indebted for the following lists : —
