ABDOMINAL MALACOPTERYGIANS. 191 



S. lemanus, Cuv. The great Trout of the lake of Geneva, which 

 is also found in some neighbouring ones ; head and back sprinkled 

 with small round and blackish spots on a whitish ground ; the flesh 

 white ; individuals are sometimes taken, weighing from forty to fifty 

 pounds. 



S. trutta,L.', Bl. 21. (The Salmon Trout). Ocellated spots, 

 or spots shaped like an X, the upper ones sometimes surrounded 

 with a circle of a lighter hue ; many of these spots on the opercula 

 and adipose fin ; flesh reddish. The finest specimens of this species 

 are taken from rivulets of clear water, which directly empty them- 

 selves into the sea, but it is found at all heights. 



S.fario, L., Bl. 22. (The Common Trout). Smaller; brown 

 spots on the back, red ones on the flanks, surrounded by a lighter 

 coloured circle, but varying infinitely as to the tint of the ground, 

 which is from a white and a golden yellow to a deep brown ; flesh 

 white; common in every brook whose waters are clear and rapid. 



S. punctatus, Cuv.; S. alpinus, Bl. 104, (The Dotted Alpine 

 Trout), but not the alpinus of Lin. ; the Carpione of the lakes of 

 Lombardy ? Dotte^j|lh small black and red points ; flesh delicious ; 

 it is found all round tne Alps. 



aS*. marmoratus, Cuv. (The Marbled Trout of the lakes of Lom- 

 bardy). Irregular, close, brown spots and streaks, so intermixed as 

 to resemble a kind of marbling, &c. •, from the lakes of Lombardy. 

 Naturalists agree in separating the 



S. salvelinus, L. ; Meidinger, 19, under the name of alpinus; 

 Truite rouge; (the Char of the English). Red spots on the flank; 

 orange abdomen ; anal and pectorals red, their first ray thick and 

 white (a). 



aS". alpinus, L. ; Bl. 99 ; Meidin. 22, under the name of salveli- 

 nus. Nearly the same colours ; but the first rays of the inferior fins 

 are not distinguished. This species fills the mountain lakes of Lap- 

 land, &c., and constitutes an invaluable supply of food to the inha- 

 bitants of that country during the summer. 



There is another small trout found in European rivers, the Samlet 

 of the English; Saumoneau of the Rhine; Penn. IH. Brit. Zool., 

 pi. lix, 1, which many consider a distinct species. The greenish of 

 the back and the white of the belly form zigzags, in each of which is 

 a red spot; it is a small, but delicious fish. 



S. umbla, L. ; Bl. 101 ; L' Ombre Chevalier. Smaller scales and 

 finer teeth than in either of the others; the spots more strongly 



J^° (a) The late Sir Humphrey Davy, who paid great attention to the anatomical 

 structure of those fishes, which are of greatest interest to the angler, suggested once 

 the propriety of establishing a new species, which would form a link between S. sal- 

 ver inus and S.fario. The new species is called the Gillaroo, and is found in the lake 

 of Loch Con, in the north-west of Ireland. He describes its appearance to be nearly 

 that of the ordinary Trout, except that it has more of the red spots, and also that it 

 has a yellow or golden-coloured belly and fins, and that it is a broader and thicker 

 fish. But its great peculiarity is its stomach, which is large and thick, and some- 

 what indurated, and generally containing small shell fish. — Eng. Ed.
