MALACOPTERYGII ABDOMINALES. 223 







S. salar, L.; Bl., 20. (The Salmon.) The largest species of 

 the genus, with red flesh and irregular brown spots, which soon 

 disappear in fresh water; the cartilaginous hook forn\ed by the 

 lower jaw is inconsiderable even in the old male. From all the 

 Arctic seas, whence it enters the rivers in the spring. The 

 value of this fishery in all northern countries is well known. 



S. hamatus, Cuv.j Bl., 98. A Avhitish ground, spotted with 

 red and black; snout of the male narrowed into a point, and the 

 hook of the lower jaw much more strongly marked than in the 

 salar. Its teeth are stronger and its flesh red, but leaner and 

 not so much esteemed. Taken at the mouths of rivers in 

 Europe. 



S. S chief ermuHeri, Bl., 103. Less than the salar, with longer 

 and ir.ore slender teeth; flanks sprinkled with little crescent- 

 shaped spots on a silvery ground; flesh yellow. Numbers of 

 this species are sent to Paris during the summer. 



S. hucho, L. ; the Hucho of the Danube and its tributaries. 

 Bl., 100, and better, Meidinger, 45. Nearly as large as the 

 salar, diff'ering but little from the preceding in its spots, but 

 has a more pointed snout and much stronger teeth. 

 With respect to the remaining river Trouts, it may be said that 

 they are found in all the clear streams of Europe, and particularly 

 among the mountains, of very diff'erent colours and sizes, among 

 which several naturalists have thought they could detect various 

 species, while others afiirm that these are mere varieties, resulting 

 from age, nourishment, and especially from the waters in which 

 they sojourn; this supposition, however, is, I think, stretched be- 

 yond the bounds of probability. 



S. lemanus, Cuv. From the lake of Geneva, and also found 

 in some neighbouring ones; head and back sprinkled with small 

 round and blackish spots on a Avhitish ground; the flesh white; 

 individuals are sometimes taken, weighing from forty to fifty 

 pounds. 



S. triitta, 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 oper- 

 cula and adipose fin; flesh reddish. The finest specimens of 

 this species are taken from rivulets of clear water, which di- 

 rectly empty 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;
