 THE ASP. 



THE Crucian, or Prussian Carp (Cyprinus Carassius, 

 Linn.), was common in the ponds, in my vicinity, as also 

 by all accounts in the Wenern, &c. ; but there it never 

 came under my observation. With the exception of the far 

 north, this fish is said to be found almost everywhere in 

 the interior waters of Scandinavia, as also in parts of the 

 eastern Skargard. 



A difference of opinion would seem to exist amongst 

 northern naturalists respecting this fish; some contending 

 that there are two species namely, the C. Carassius, Linn., 

 Sjo-Ruda, or lake-crucian, Sw. ; and the C. Gibelio of 

 Bloch ; Damm-Ruda, or pond-crucian, Sw. ; whilst others 

 again, and amongst the rest Ekstrom, are of opinion that 

 they are one and the same ; and that the difference observable 

 in size and colour is solely owing to locality ; and from 

 their synonyms, habits, &c., nearly agreeing, this view of 

 the matter would appear to be the proper one.
