Introduction. 
Since " A List of the Fish Fauna of the Millstone Grit Rocks " 
— by the writer — appeared in the Geological Magazine in 1901,* 
fresh material has come to hand which makes a slight revision 
of the list in one respect necessary, whilst on the other hand, 
three new fish-bearing localities are added, and also several 
genera which are new to these rocks.
