THE FRESII-WATER FISHES OF EUROPE. 



twice the orbital diameter in width, and in the adult fish the eye is the same 

 distance from the snout, but in the young- fish the snout is a little less eloni^ated. 

 The nares are near to the orbits ; the jaws are loii<^, reachiiii^ under the eye. 

 The cei)ha]ic canals are large and open, with numerous pores, and are par- 

 ticularly conspicuous in the sub-orbital and frontal areas. The dorsal profile is 

 a Hat arch. 



The dorsal fin commences behind the middle of the body over the 

 thirty-fifth to thirty-seventh scale of the longest longitudinal row. It is 

 higher than long. The ventral fins are a little in fiont of the dorsal; their 

 longest rays are shorter than those of the dorsal fin. The anal fin com- 

 mences Ix'hind the termination of the dorsal ; its rays are shorter than those 

 of the ventral. The longest rays of the pectoral fin are equal to tho' <i

of the eaudal iin. As in the allied s];ecies, the scales have rays diverging 

 in a fan shape at the free border ; they usually number ten to twelve, 

 but as the largest scale is scarcely half the diameter of the eye, 

 the rays appear to be numerous. The colour of the back is brownish- 

 green, but the sides towards the abdomen are of burnished silver. All the 

 fins are yellowish, without a black border, and there is no longitudinal lateral 

 band as in L. hrrslyi; but, as Canestrini remarks, this latcu'al band fre- 

 (juently disappears in L. mtiticeUus, L. anld, and other forms. 



This species is only found in Dalmatia, in the River Narenta, near 

 Vergoraz, and in the Lake of Dusino, near Imosky, where it usually reaches 

 a length of six or seven inches, and is occasionally a foot long. 



At Vero'oraz it is known as the Maldl.
