540 TEN YEAES IN SWEDEN. 



in the sea, but in May or June countless thousands come up 

 on to the northern coasts of Finland to spawn, followed 

 by shoals of cod and other fish, who prey upon them. The 

 scent of the lodda is even stronger than that of the smelt, 

 and highly attractive to the large fish of prey, on which 

 account they are in such request for bait, that in 1786, 

 when the great cod fishery off Lofoden was in the hands 

 of the Danes, it was forbidden to use this fish as bait because 

 all could not procure it. 



Colour : on the back green, on the sides silvery white ; 

 the position of the scales forming longitudinal bands along 

 the sides. The Scandinavian specimens have not ex- 

 ceeded 8 in.

(All the species of the salmonidce which have been 

 hitherto described, are characterized by a wide gape, and 

 sharp teeth. The three next genera, tliymallus, coregonus, 

 and argentincij have a very small gape, very few teeth, but 

 the body on the contrary is covered with much larger 

 scales). Breast armed with a band of scales, which 

 stretches far beyond the pectoral fins ; dorsal long and 

 high.

May always be distinguished by the long high 

 dorsal fin, with 20 rays, and the dusky longitudinal 

 streaks along the sides of the body, as well as by the 

 long dorsal fin ; scales on lateral line, 90 to 92 ; scales 

 large, lie in longitudinal rows. 



Is principally confined to the northern lakes and rivers, 

 and although I have met with small ones in the Klar, near 

 its outlet into the Wener, I never saw them taken further 

 south. They spawned with us in May, in Lapland in June. 

 The largest I ever saw was one I took at Quickiock, which 

 weighed above five pounds.
