512 TEN YEAES IN SWEDEN. 



74. LEUCISCUS KUTILUS, Cuv. Mort. The Koach. F. D. 

 Is certainly the commonest of all the genus, and is met 



with from the extreme south of Scania far up into Lapland. 

 They run to a large size, a roach of a foot long not being 

 so very uncommon. They say here that the male fish appears 

 on the spawning grounds a fortnight before the females; 

 and the fishermen call the former the " Is mort/' the latter 

 the e ' lek " or ' ' lof inert." They generally spawn about the 

 beginning of May. I hardly believe that we have two 

 distinct species of roach here, but certainly the very dif- 

 ferently-coloured fish we take in distinct waters would almost 

 favour this supposition. 



75. LEUCISCUS PHOXINUS, Cuv. Elritza. The Minnow. 



D. F. 



Is met with in all little streams, and in many of the 

 large lakes, from the extreme south of Sweden far up into 

 Norway. Usual length 3 to 4 in., but I have taken them 

 in Wermland more than 5 in. Is common in the brackish 

 waters of the Gulfs of Finland and Bothnia.

 rally high and compressed.
