such as Physa and Neritina flumatilis in their 

 stomach. The latter, it may be remarked, is very 

 thick and muscular, not unlike that of the Charr or 

 Gillaroo Trout. Whatever may be the case in some 

 parts of the Continent, Grayling certainly never 

 seek the sea in this country; nay it has been 

 proved that they speedily die even in brackish 

 water. 



The distribution of the Grayling in this country 

 is rather remarkable, and viewed in relation to 

 England, would almost give countenance to the 

 opinion alluded to in Salmonia, that it has been 

 introduced to our rivers. In the work just men- 

 tioned, its localities are stated to be the Avon, in 

 Hampshire ; the Severn, and the tributary streams 

 which form it, in North Wales ; the Wye and its 

 tributary streams ; the Lug, in Herefordshire ; the 

 Dee, the Dove, Trent, Blithe; in Yorkshire, the 

 Kibble, Erne, Wharf, Humber, Derwent, and Rye. 

 It is also occasionally taken in the Eden and Esk, 

 in Cumberland. These may be considered its most 

 northern localities on the mainland ; but Lowe 

 affirms that it is very frequent in the Orkney 

 Islands. We believe that the Grayling has not 

 been found in Scotland, and certainly this hiatus in 

 its distribution is not a little singular, the more 

 especially as, being an alpine fish, naturally fond of 

 cool water, and abounding in much more northern 

 countries on the Continent, the Highland rivers 

 seem peculiarly adapted for it. Neither has it been 

 observed in Ireland.
