64 THE CHUB. 



The dobule roach, or what Mr. Yarrell, who examined 

 several specimens brought from the Wenern, and myself 

 considered to be such, was common as well in that lake as 

 the Gotha. 



Of its habits little or nothing seemed to be known in my 

 vicinity, and this from the resemblance it bears to the common 

 roach, with which indeed the fishermen, until the difference 

 was pointed out to them by me, always appeared to identify it. 

 As a consequence, it had no specific name with us ; but in 

 the Falkenberg River, which is upwards of one hundred miles 

 to the southward of the Wenern, it is called the Har-nacke, 

 or something similar. 



In my neighbourhood I only remember seeing it captured 

 in nets, or on night-lines laid out for pike, perch, &c., to 

 which an odd one was at times found appended. But in the 

 Falkenberg River, where ide are also plentiful, it is commonly 

 taken with the fly. 



The weight of the dobule roach, according to the fisher- 

 men, as well in the Wenern as in the Falkenberg River, 

 seldom exceeded two pounds ; but generally it was not more 

 than half that weight. 



The Chub (Farna, Sw. ; 0. Cephalus, Linn.) was, accord- 

 ing to Swedish naturalists, an inhabitant of the Gotha, 

 where, as said, it goes by the name of Dick-kopp. Un- 

 fortunately, however, I was unable to procure a specimen 

 of this fish, before leaving Sweden, to compare with the 

 C. Dobula (or what I presume to be such), with the 

 characters of which, as before observed, it in the main 

 agrees. By the description of the fishermen, however, there 

 is little doubt it did exist with us. 



It was not until of late years that the C. Cephalus was
