back as the eye. The cheek is marked with asperities, and is free from the 

 pits and depressions in front of the eye in the type. The operculum has a 

 rough, irregularly furrowed surface. Fig. 43 shows the pharyngeal teeth. 



According to Blanchard, the scales are larger than in the Crucian Carp, and 

 though they have the same form, the concentric striae are farther apart,

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 Blanchard, and five to 

 six in the German and Austrian ex- 

 amples. The colour is more uniform 

 and less bright than in the Crucian 



Carp, the back being blackish-green, changing to bluish, and the belly brownish- 

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

 their bases ; the other fins are black. The iris is greenish-black.
