of the Tweed is the Salmon Trout, and not the young 

 Bull Trout, which now goes by the name of Trout 

 simply." 



THE GKEY, BULL TROUT, or ROUND TAIL. 



Salmo Eriox, Linn. 



" The Grey Trout," says Mr. Yarrell, " is distinguished 

 from the Salmon and Salmon Trout by several specific 

 peculiarities. The gill-cover differs from them decidedly 

 in form, and the teeth are longer and stronger." The 

 tail grows square at an earlier period than in the Salmon ; 

 and the central caudal rays continuing to elongate 

 with age, the whole tail, originally concave, eventually 

 becomes convex, and from thence it has been called the 

 Round Tail. The elongation of the under jaw is peculiar 

 to the males only, and is less than in the Salmon. The 

 scales also are less, the shoulders thicker, and the tail 

 more muscular. In short, it is altogether a more thick 

 and powerful fish than the Salmon, and consequently 

 gives the angler more sport ; but to the epicure it gives 

 less, as it is inferior in flavour and colour, and if not 

 very fresh from the sea its flesh is short and woolly. It 

 is very much the colour of the Salmon, but tinted with 

 grey or brown spots. 



These fish are found in many salmon rivers, but not 

 in all. It is very abundant in the Tweed, which it 

 visits principally at two seasons ; in the spring about the 

 month of May, and again in the month of October,
