FISHES. 515 



Little appears to be known of the habits of this fish, 

 but most probably they much resemble those of the other 

 breams. 



The Pomeranian bream, A. Buggenhagii, Bl., is not in- 

 cluded by Nilsson in the Scandinavian fishes ; but Mr. Lloyd 

 says, " We had another bream, called by the Wener fisher- 

 men { Sjo Ruda/ or Lake Carp, but of what species I can- 

 not exactly make out. Mr. Yarrell, to whom I submitted 

 several specimens brought from the Wener, is inclined to 

 think it the A. Buggenhagii, Bl." 



This Pomeranian bream rather resembles the wimma, and 

 might even be taken for a young of the brama or balleruSj if 

 the smaller number of rays in the anal fin (18 to 19), did not 

 prove it to be a distinct species. According to Valen- 

 ciennes, it most resembles A. Bjorkna; scales on the lateral 

 line, 48.

Bjorkna. The White Bream, or Breamflat. F. D. 

 Not so deep as the common bream. May always be 

 known by its shiny silvery appearance. Is very common 

 in many of the Scandinavian waters, as far north as Up- 

 land. The young fish resemble the roach, the older ones 

 the young bream. It is, therefore, not an easy fish to 

 identify, except by a careful examination of fin rays and 

 scales on the lateral line. They spawn here in June. 

 The habits are the same as those of the rest of the 

 family. Usual length, 10 to 11 in. ; height, 4 in. 

 Is tolerably common in Ladoga, in Finland. 



B. Under jaw longest. 

 Aspius, Agass.

This is another of the genus which in shape much 

 resembles the gwynniad, but it may be easily known by 

 the very projecting under jaw and the larger mouth; eyes
