THE FRESH- WATER FISHES OF EUIIOPE. 



In Italy it is known as the Savetta. Its habits are like those of the 

 Nasling-. It is taken indifferently in large lakes, like Garda, and in rivers. 

 It is captured with the line and net, and is sufficiently abundant to be a 

 cheap food for the poorer classes, both in Italy and Montenegro. 



Chondrostoma knerii (Heckel). 



D. 11, A. 1^. Scales : lat. line 5:i — 54, transverse 9/(). 



This little fish, which does not exceed six and a half inches in length, is 

 limited, so far as is known, to the river Xarenta, in Dalniatia (Fig". 112). 



It is characterised by a rather blunt head, with four pores on each side of

the lower jaw, long pectoral fins, semicircular mouth (Fig. 113), and six 

 pharyngeal teeth on each side. The strongly-curved mouth and fewer rays in 

 the dorsal and anal fins distinguish it from Ch. nasns and CJi. soi'fld, while the 

 blunter head, longer pectorals, and number of pharyngeal teeth, separate it 

 from Ch. genei. 



The fish is five and two-third times as long as the length of the head, 

 and five and a quarter times as long as high. The height of the head is four- 

 fifths of its length. 



The diameter of the eye is not quite one-quarter of the length of the 

 head ; the breadth of the frontal interspace between the eyes exceeds the 

 diameter of the eye, and the eye is a similar distance from the snout. The 

 angle of the mouth does not reach to the nares. The dorsal profile is a more 

 regular and somewhat higher arch than the ventral outline. 



The fins resemble those of Ch. goiei, both in ]iositioii and form ; but 

 the rays of the anal ai"e longer, so that the length of the base is two-thirds
