This elegant species grows to the length of 

 about eighteen inches, and is an inhabitant of the 

 clearer and colder kind of rivers in many parts of 

 Europe and Asia ; particularly such as flow through 

 mountainous countries. In England it is found in 

 the rivers of Derbyshire ; in some of those of the 

 North ; in the Tame near Ludlow ; in the Lug and 

 other streams near Leominster, and in the river 

 near Christchurch in Hampshire*. In Lapland it 

 is said to be very common, where the natives make 

 use of its intestines instead of rennet, in preparing 

 the cheese which they make from the milk of th© 

 Rein-Deer. 



The shape of the Grayling resembles that of the 

 Trout, but is rather more slender : its colour is a 

 beautiful silvery grey, with numerous longitudinal 

 deeper stripes, disposed according to the rows of 

 scales, which are of a moderately large size : the 

 head, lov/er fins^ and tail, are of a brownish or rufous
