list it will be seen that Sutherland possesses all, or nearly 
all, that are known. 
Scarcely a river in the east of Sutherland produces a 
trout possessing any edible qualities, probably from the 
generally stony nature of the streams, and consequent lack 
of food ; but the lochs of the east almost all contain good 
red-fleshed and firm trout. In the west, amongst the lime- 
stone districts, the white-fleshed trout of the burns are 
most delicious eating, and so also are the trout of many of 
the lochs of Assynt, which are pink in flesh. The very 
dark red-fleshed trout of Gorm lochs are flabby and " out 
of season" in June and July, when ova are often found 
in them. We could say a great deal more in detail, but 
space forbids in this place. 
Varieties of trout (Salmo fario) are as follows : — 
a. Salmo feroXfJ&vd. and Selby. Great lake trout. General 
in the larger and deeper lochs, and even found in 
the shallow Loch Borrolan. 
b. S. cornuhiensis, Walb. Parr-marked trout. Lochan 
Sgearach, Eeay Forest : above a fall of some sixty 
feet. Specimens caught in June 1883 ran three to 
the pound and larger. Strong and active. Parr- 
marks fade after death. 
c. S. esticarius, Knox. Tidal trout. " Fossak " of Loch 
Inver. Ascends rivers only a limited distance, 
varying in different streams. Euns 2 to 5 lbs. 
weight ; white-fleshed ; coarse, rich food, if in 
season. Appears in May. Disappears in August. 
Strong. 
d. S. stomachicus, Giinth. Gillarroo trout. Loch Mulach 
Corrie, on the top of the Assynt limestone, and base 
of Ben More. Doubtful if this is separable from 
the Irish examples. Flesh pale pink ; delicious 
eating ; runs to 5 or 6 lbs. (rare) weight. Strong 
and active. Another trout, or the young of this, is
