and the canals are less numerous. The basal border of the scale is marked 

 with very slight curvatures, and has not the festooned character of scale seen 

 in the Crucian Carp. In Alsace and Lorraine these differences appear to be 

 constant. The variation in the fins is less conspicuous. The dorsal fin is less 



elevated, and is stated by Blanchard 

 to have twenty-one branched rays, as 

 in some examples from Central Europe, 

 though Austrian specimens have only 

 fourteen to sixteen. The anal fin has 

 seven branched rays in the specimens 

 described by Blancliard, and five to 

 six in the German and Austrian ex- 

 oiiiELio. amjjles. The colour is more uniform 



and less bright than in the Crucian 

 Car]), the back l)eing ])lnekish-greeu, changing to bluish, and the belly brownish- 

 yellow, with a golden tint. The pectoral and ventral fins are reddish-l)rown at 

 their bases ; the other fins are black. The iris is i>'reenisli-black.
