FISHES. 517 



front of the anal fin forming a sharp edge ; nose very 



blunt and turned up. 



This fish, whose native home is North Germany, Prussia, 

 etc., where it is said to attain a length of 18 in., must be con- 

 sidered as one of the rarest of Scandinavian fish, only one 

 specimen having been taken in this country, and this was 

 procured by Linnaeus himself, in Christianstad, in the south 

 of Sweden. Is met with in the Lake Ladoga. More 

 properly belongs to the Black and Caspian Seas. 



Gen. Colitis, L. 



Dorsal and anal short ; mouth under the nose bearded ; 

 body elongated, round, covered with slime and small scales ; 

 tail fin square ; gill openings small. 



83. COBITIS BAEBATULA, L. Gronling. The Loach. F. D. 

 Is certainly a very rare fish in Sweden, if it is ever found 



here, of which there appears to be a doubt. I never saw 

 a Swedish specimen. Sides of the head unarmed. Common 

 in Finland up to 65. 



84. COBITIS T^NIA, L. Nissoga. The Spined Loach. F. D. 



Beneath each eye is a forked spine. 



Is met with, according to Nilsson, in many places in the 

 middle of Sweden, and I have seen several specimens taken 

 in the Wener. Is certainly more plentiful in Scandinavia 

 than the last. 



Fam. 2. EsocmaE. 



One dorsal fin, set far back ; head flat, with wide gape ; 

 body long ; both covered with hard scales ; teeth formidable. 



Gen. EsoXj L. 



Inter-maxillaries forming two-thirds of the upper jaw ; 

 fresh waters ; live singly. 



85. Esox Lucius, L. Gadda. The Pike. F. D. 



Is the commonest of all the Scandinavian fresh water fish,
