LEUdSCUS PAUSINGEUI. 



149 



Heckel and Kner record that varieties, with the eyes large and forehead 

 small, are obtained from the Oder, from ponds in Lemberg and Lake 

 Constance, and spread over the north of Europe. Another variety, with 

 large eyes and deep body, occurs in the Neusiedler See and Flatten See. A 

 variety, with small eyes and a broad forehead, is found in the Danube and 

 its tributaries, and in the Traun and Atter See. 



A more marked variety was distinguished as Leuciscns pauslngeri of 

 Heckel (Fig. 74). It is characterised by having the dorsal fin higher, with 

 a shorter base, and lower anal fin than in the typical forms of the Roach.

It is four times as long as high, and five and a half times as long as the 

 head. The frontal profile rises steeply to the back without an intervening 

 depression. The eye is one-fourth of the length of the head. 



The beginning of the dorsal fin is exactly opposite the ventral, and is one- 

 third higher than long ; its upper border is more concave than in the type. 

 The anal fin is as long as high. The pectoral and ventral fins are of the same 

 length, and the pectoral reaches nearer to the ventral, than does the ventral 

 to the vent. 



The eye has a deep-red iris. The largest example is nine inches long. 

 This variety is found at Egel See, in Upper Austria.
