76. ABEAMIS WIMBA, Miss. Wimma. F. D. 



Is scarcely so broad as many others of this family, for 

 the greatest height of the body is equal to only one-fourth 

 of its length. In fact, as Mr. Lloyd observes, it much more- 

 resembles the young of some species of Coregoni, but is 

 readily distinguished by the absence of the adipose fin. It 

 may be easily recognized by its thick projecting snout. I 

 do not believe that they attain any very large size, although 

 I have seen them taken in the Wener about a foot long. 

 They appear to be most common in those rivers that run 

 into the Baltic, where many of them winter in brackish 

 water ; but about the end of May they ascend the rivers to 

 spawn in clear running water. They abound in some parts 

 of the lake Wener ; they are not considered of much value 

 for the table ; appear to be very common in the Gulfs of 

 Bothnia and Finland, and also in Ladoga; come out of the 

 large lakes and the Baltic, where they winter, into the rivers 

 about May to spawn. The long, projecting snout and rounder 

 body marks the wimma. Colour brown above; sides, sil- 

 very, tinged with yellow ; pectorals reddish brown ; ventrals 

 more red ; anal paler.
