136 IDENTITY WITH THE VENDACE. 



Coregoni mentioned, by its having the lower jaw longer 

 than the upper, and from never exceeding seven to eight 

 inches in length. 



The Cor eg onus Albula, Linn., called with us the Sik- 

 Ib'ja, or Sik-bleak, from its partial resemblance to the true 

 bleak, as also the Sil, was common both in the Gotha and 

 the Wenern, and I believe in most of the lakes and rivers 

 throughout Scandinavia. It is an inhabitant, likewise, of 

 the eastern Skargard, but not I believe of the western. 



The Coregonus Albula, in appearance, greatly resembles 

 the Vendace, described by Sir William Jardine as an inha- 

 bitant of Lochmaben in Scotland, and its habits are similar. 

 It keeps in large shoals ; it never attains to any considerable 

 size ; would never, as far as our experience went, take a bait ; 

 and it was only once now and then when near to the surface, 

 that we could lure it with a small artificial fly. It is, in fact, 

 but rarely captured, excepting in nets ; and is so delicate as 

 to die almost as soon as out of the water; even if trans- 

 ferred at once to the Sump, or fish-box, which with me was 

 capacious, and placed in the stream itself, it lived but a very 

 short time. 



With us, this fish spawned towards the end of October or 

 in the beginning of November. The young were called 

 Sil-Guppor, in contradistinction to Sik-Guppor, the young 

 of the Sik. 



Swedish naturalists speak of a second species of the 

 smaller Coregoni, which from being found in the lake 

 Animmen in Dalsland, they designate as the Anims- 

 Wimma the Salmo Wimba of Linnaeus, which is described 

 as differing from the C. Albula in having the adipose fin 

 slightly serrated.
