FOSSIL FISH REMAINS. 



173 



From the Bhaly portion of the Limestone series I have succeeded 

 in obtaining remains — in the shape of teeth (except where otherwise 

 stated) — of the following thirty species of fossil fish. For considerable 

 assistance in the nomenclature of the specimens, rendered difficult by 

 their fragmentary condition, I am indebted to Mr. William Davies, 

 F.G.S., of the British Museum, and Mr. John Ward, F.G.S., Longton, 

 Staffordshire, to whom I wish now to express my thanks. 



To the list of Ticknall species here given I append the chief 

 English and Irish localities at which they also occur : — 



The following additional genera and species have been described b> 

 M'Coy, in his contributions to British Palaeontology, as occurring in 

 Derbyshire, chiefly at Ticknall : — 



Acrolepia Hopkinsii. M'C*y. 

 Cheirodus pes-raDee. M'Coy.
