FISHES. 511 



time whether our British chub was an inhabitant of the 

 Scandinavian waters. It is now, however, clearly proved 

 that such is the case, and, according to Malmgren, all 

 the different synonymes quoted belong to this fish and 

 no other. Although found in many of the Scandinavian 

 waters (especially in the middle of the country), and 

 even far up in Finland, where they attain a weight of 

 8 to 10 lb., it is, I fancy, nowhere so common as the ide, 

 nor does it (in Wermland at least) run to so large in size, 

 although Bkstrom mentions having seen one 22 inches long, 

 and another weighing 7 to 8 lb. But Mlsson gives the 

 general size as 8 to 10 in. in length, and this is, I think., 

 pretty correct, certainly in the northern tract of the 

 Wenern. They spawn here in June. Is not included in 

 the list of Danish fishes, unless it goes under the synonyme 

 of L. Dobulcu or L. Grislagine, which I fancy is not the case. 

 It is singular, however, that Mr. Lloyd gives us a figure of 

 the dobule roach in his " Scandinavian Adventures,"" and 

 remarks : " The dobule roach, or what Mr. Yarrell, who 

 examined several specimens brought home from the Wener, 

 and myself considered to be such, was common as well in that 

 lake as in the Gotha." This does not agree with Malmgren, 

 who denies the existence of the dobule roach, as a distinct 

 species, in either Britain, Denmark, or Sweden. It is my 

 opinion that the confusion respecting the identity of some 

 of the different members of this genus is not cleared up, 

 and I do not believe that we have the true dobule in 

 Sweden.

Is very common in the south and middle both of Sweden 

 and Norway, but I believe it is not ascertained precisely 

 how far north it is met with. They spawn here early 

 in June. Their general length is about 8 in., but I have 

 seen them larger; may always be known from the roach 

 by the deeper body, the bright vermilion fins, and the carp- 

 like colour of the scales.
