ABDOMINAL MALACOPTERYGIANS. 191 



*$*. 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 ? Dotted with small black and red points ; flesh delicious ; 

 it is found all round the Alps. 



S. 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 



aS*. 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). 



S. 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. 111. 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 



|ggp° (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- 

 verinus 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.
