PLATE CXIf. 
This is the Torgoch or “ red belli/" of the Welsh, a fish at 
present confined to the waters of the Llyn Quellyn, one of the 
alpine lakes, situated in the deep valley on the west side of Snowden* 
The Torgoch inhabited the Llanberris lake on the opposite side of 
the mountain till within the last twenty years, since which time 
they have entirely disappeared : — it is believed that the noxious 
waters of a neighbouring copper-mine flowing into the lake has 
destroyed the blood, as those fish inhabit only the purest waters. 
Llyn Quellyn is a vast lake, of unknown depth, sheltered on one 
side by an abrupt mountain, which rises immediately out of the 
water, and in the deep recesses at the base of which the Torgoch is 
supposed to pass the milder seasons of the year in perfect security. 
Those fish approach the shallower parts of the lake in winter, about 
the middle of December, appearing in small troops at a short dis- 
tance from the shores, and are at this season taken in some plenty 
by a poor cottager, who resides in the vicinity of the lake, and de- 
rives a small annual profit from the fishery ; this delicious fish being 
in much request for the tables of the neighbouring gentry. 
This fish differs from the Charr of Wynandermere, in West- 
moreland, and can be no other in our idea than the true Salmo 
Salvelinus. The Torgoch spawns later in the season, and never 
increases to a size much larger than that represented in our plate, 
which is scarcely half the dimensions of the other. The outline is 
more slender, and the colours in point of splendour far superior. 
The lower jaw in the Torgoch, contrary to the Gmelinian cha- 
racter of Salvelinus, projects rather beyond the upper one, and 
in this respect accords with Alpinus: it must, however, be recob. 
ieeted, that the elongation of the lower jaw in the Salmo tribe is
