550 TEN YEAES IN SWEDEN. 



only a variety of the C. albula, or vendace. Be this as it 

 may, it seems as yet only to have been met with in one place 

 in Scandinavia, the lake Anim, in Dalsland, where Linnaeus 

 first discovered it, and where the fishermen distinguish it 

 from the common vendace by its brighter scales, its smaller 

 eyes, and different form of mouth. They never appear 

 to migrate, but always keep in deep water, and never 

 approach the shore. They spawn in the end of October, 

 and the spawning season lasts two months. 



106. COEEGONUS ALBULA, Val. Sik Loja. The Yendace. F. 



Body lengthened, round, compressed at the sides ; its 

 height less than the length of the head, which is as one 

 to five of the whole body length ; usual length 5 to 6 

 in. ; colour and fin ray formula as in the last. 

 Is met with in most of the lakes in the middle of Norway 

 and Sweden, and goes far up into Lapland. In our midland 

 lakes they spawn about November and December. 



Gen. Argentina, Art. 



Much resembling the smelt in appearance, but the posi- 

 tion of the dorsal fin before the ventrals will at once distin- 

 guish this genus. Live only in the sea, and except, as 

 young fish, never approach the coasts. 



107. ABGENTINA SILUS, Miss. Storre Silfver Fisk, Sw. 



Gull Lax. Las Sil, Norw. 



About 18 in. long; sides of the body in the young 

 fish silvery white, in the older ones yellowish ; scales 

 broad, sharply serrated at the hinder edge. Fin rays : 

 D. 11; P. 17; A. 1415; vertebra 65; eye very 

 large, equal to one-third of the length of the head. 

 Is found on the western coast of Norway, especially off 

 Bergen, where they occasionally attain a length of two feet ; 

 in summer they live at the depth of eighty to a hundred 

 fathoms, in company with the sebastes. 



The spawning season is not precisely known, but is pro- 

 bably either in autumn or spring. May be considered a rare 

 fish.
