THE FISHES OF THE LOWER WHARFE BASIN.* 
G. WADDINGTON. 
THE following notes have reference to the lower half of the 
River, though no actual line of demarcation can be fixed except 
at the eastern extremity. 
There are only a few references to the higher reaches of this 
stream, as my experience does not extend to within some little 
distance of its source. One writer seems to have made a special 
study of the Icthyology of Upper Airedale,t but although no 
river in Yorkshire is so well known to naturalists, anglers, and 
sportsmen generally, I have not been able to find a similar 
account of the fishes of the River Wharfe. 
In the Lower Wharfe Basin are both migratory fishes, such 
as the Salmon, Eel, and Flounder; and ‘fishes which are not 
capable of existing in salt water, nor have the desire of attaining 
the sea if they could do so. 
The following is a catalogue of Fishes found in the Lower 
Wharfe Basin, based on Giinther’s classification :—
