SPECIES OF SALMO. 1 1 9 



In addition to the several species of the genus Salmo 

 enumerated, Nilsson includes the 8. Ocla, Nilss., and the 

 8. Truttula, Nilss., in the Scandinavian Fauna. But unless 

 one or other of these fish be identical with the 8. Eriox 

 of Linnaeus, I am not aware of their having come under 

 my observation. 



The 8. Ocla, the Professor tells us, is found in the 

 river Dal, and perhaps in other rivers. It arrives from 

 the Baltic about the summer solstice that is, somewhat 

 later than the 8. 8alar, and spawns at the same time as 

 that fish. Its flesh is white ; length, hardly two feet, and 

 it seldom exceeds four to five pounds in weight. 



The 8. Truttula, Nilss., according to the Professor, ascends 

 from the sea to rivers and lakes. Length, from twelve to six- 

 teen inches ; the flesh pale, scarcely reddish ; has examined 

 specimens from Gothenburg and the lake Wettern. 



The Charr (Roding, Sw.), though not found in the 

 Wenern or the Goth a, inhabits several of the waters of 

 the peninsula. 



Although some of the best European authorities admit, 

 I believe, of only one species of Charr, Nilsson includes 

 no less than six species in his Prodromus. 



1. The 8almo alpinus, Linn.,* which, as the name would 

 denote, is confined, I believe, to the more alpine regions of 

 the peninsula. Leestadius, when speaking of this fish, says : 



" The under part of the belly is red ; the back, dark 

 green ; the sides, which are sprinkled with small round spots, 

 intermediate between red and green. It is the handsomest 

 fish in our waters. It would seem properly to belong to the 

 fjall lakes, of which, with the exception of a single species 

 of trout, called in Lappish Tabmo'k, it is the only inha-
