CYPKIXUS llUNGARICUf 



101 



The dorsal fin beg-ins half-way down the body, and is two and a third 

 to two and a half times as long- as high. Its base is nearly always less than 

 one-third of the length of the fish. The anal fin may be twice as deep as 

 long, though commonly less ; its bony ray is relatively strong. The caudal 

 fin is more developed than in the Cijprinns carpio, and has the lobes more 

 pointed. This variety is also found in the Flatten See and the Neusiedler See. 



The Cijpnnus Iiangaricits (Fig 81) is a variety with a more elongated 

 and more cylindrical body. The height of the body in old specimens is equal 

 to the length of the head, but usually it is a quarter of the length of the

body, or rather less. The thickness is never less than half the height of the 



body, and may incrense to four-fifths in old age (Fig. 35). The eye is 



larger than in C. carpio, its diameter being one-fifth of the length of the 



head, while in C. carpio it is one-sixth of the length. The position of the 



mouth is relatively lower, and the gape only curves slightly downward. Both 



pairs of barbels are longer than 



in C. carpio. The ventral outline 



is nearly horizontal between the 



pectoral and anal fins, while the 



dorsal outline is a very flat arch 



on the back, becoming in old age 



almost horizontal to the end of 



the dorsal fin. The caudal fin is 



more deeply forked, and has more 



pointed lobes than the typical 



forms of the species. The pharyngeal teeth ( Fi
