THE BULL-TROUT 249 
the scientific name Salmo cambricus to what is known as the 
bull-trout on the Tyne of Northumberland, and throughout 
Scotland, except on the Tweed, where it is called the sea-trout. 
But then it appears to me, who have seldom seen it, that the 
sewin of Wales, designated Sa/mo cambricus, must be a totally 
different fish in habits and appearance from the bull-trout, 
with which I am very familiar. I propose, therefore, to say 
nothing about the sewin, for the very good reason that it could 
only be a repetition of the description of this fish by other 
persons, and they are far from agreeing in their accounts. 
Couch, for example, describes the sewin as having pale pink 
spots and a deeply forked tail, features quite foreign to 
Salmo eriox of Linneus, in which the spots are all black, 
and the tail is always, in adult specimens, nearly square at 
the end. Mr. Houghton speaks of the excellent qualities of 
its flesh, and says that it competes with the salmon-trout in 
esteem as a sporting fish. In neither of these respects is the 
bull-trout of northern rivers to be commended, for its flesh is 
very far inferior to that of the salmon, and it comparatively 
seldom takes a bait or fly except in the kelt stage. 
As to the English names of this fish, that of sea-trout is 
perfectly applicable and correctly descriptive, but so long as 
the specific distinction is maintained between Salmo eriox and 
S. trutta, there remains the objection that throughout Scotland, 
except on the Tweed, the last-named fish is popularly known 
as the sea-trout. The term “bull-trout,” implying “big or 
coarse trout,” seems peculiarly appropriate to Sa/mo eriox, which 
runs to a far larger size than any other of the family in Britain, 
always excepting the salmon. Fig. 3. on Plate IX. shows a 
bull-trout taken in the net below Perth in June, 1899, weighing 
40 |b., and fish of this species are commonly taken in the 
Tweed from 8 lb. to 15 lb. in weight. The size, therefore, 
of the bull-trout entitles it to rank next the salmon, to which 
fish it closely approximates in habits and appearance. 
Superficially, the two fish differ from each other in the
