existed hitherto in the identification of all these fish, some naturalists 

 here appearing to confound the dobule roach with the chub, and 

 others the real dace with the dobule roach. According to Mr. 

 Couch, the Swedish Cyprinus Grislagine (Stamm). is nothing more 

 or less than the true dobule roach, and this is very common both in 

 the Wenern and the Clar. The British dace has not yet been iden- 

 tified in Sweden. I think it would avoid confusion if it were to 

 retain the old synonym of C. Cephalus, for the common chub. 

 Nilsson's Swedish name for the chub (" Bred-pannad Id," broad- 

 forehead ide) is not bad. The fishermen in the north-east of the 

 Wenern describe to me a fish which they call the stam, and for the 

 life of me I can't make out what it is, unless it be the asp (C. Aspius, 

 Lin.). They say that this stam comes up from the Wenern every 

 May to spawn in a small stream near Christineham. They remain 

 only a few days on the spawning-ground, and are never again seen 

 or taken by them out in the Wenern. They describe them as large 

 fish, from ten pounds to eleven pounds, so it is clear they can't be 

 the dace which we call the "stam/' and unless it is the asp, which 

 they assure me it is not, I cannot make out what it is. 



There is, however, no mistake about the ide (C. Idus, Lin.), 

 which certainly is commoner in these waters than the chub, call 

 this latter fish by what synonym we may. The ide runs to a large size 

 here : five to six pounds is a fine, bold fish, gives excellent sport 

 both with the bait and fly, and, in my opinion, is no bad fish for 

 the table. The chub may be easily distinguished from the ide, 

 which it much resembles in shape, by the round anal fin and the 

 large scales. According to Kroyer, Yarrell's ide is not the same as 

 the ide which he figures in his Danish fish, which species, although 

 he says it is identical with our Swedish fish, he also says does not 

 belong to Britain. 



The asp (C. Aspius, Lin.), another fish unknown in Britain, is 

 common in some parts of the Wenern, but local. It is a fine fish 

 in shape, rather resembling the chub, but more elongated, of a 

 more silvery colour, and its distinguishing peculiarity is the long 

 under-jaw, which protrudes far beyond the upper one. They run
