G.pundatissimus) ; or descend the rivers and enter the sea at regular intervals 



such as the Eels, also Salmo carp to and Salmo trutta ; or ascend the rivers 



at certain seasons, chiefly for the purpose of spawning, such as the Shad, 

 which only ascend the rivers in spring, the Sturgeon, and the Lamprey. 

 The fresh-water Perch is also occasionally met with in brackish water. 



Amongst the sea-fishes, the Italian Flounder (Pleuronectes italicus) 

 frequents brackish waters, and even -sometimes enters the rivers ; some fre- 

 quent and prosper in the Lagoons — such as the Atherines, two Blennies (Bl. 

 gattorugine, Bl. galerita), Sea-horses, and the Greater Pipe-fish ; others only 

 occasionally frequent the lagoons and brackish waters — such as the Three- 

 bearded Rockling, the Turbot, Brill, common Sole, Basse, several species of 

 the Grey Mullet tribe, the Gilt-head, the Black-fish {Centrolophus pom- 

 pilus), Mama vulg. and Sargus vulg. ; whilst others only frequent the 

 deeper channels in the vicinity of the lagoons, such as — the Black Bream, 

 the Umbrina, the Red Mullet, the Sapphirine Gurnard, also Gobius paganelhis, 

 Lichia amia, Scomber pneumatophonis, the Horse Mackerel, and the Gar- 

 Pike. 



The Bogue, the Flying-fish, the Pilot-fish, the File-fish, the Molebut, 

 also Carcharias Milberti and Falx Venetorum, are only accidentally met with 

 in the laeoons and brackish waters. 



The Eel, Flounder, Turbot, Sole, Gilt-head, Basse, Sand-smelt, five grey 

 and two red Mullets, and three Gobies are reared in the lagoons, the Mullet 

 species, Turbot, Sole, and Gilt-head being introduced as young fry. 



Only 126 species belonging to 86 genera of the sea-fishes, and 24 

 species belonging to 18 genera of the fresh -water fishes extend to British 

 waters . 



Of the sea-fishes, 125 species are more or less common all over the 

 Adriatic ; 70 species are more or less rare ; 90 species are so rare as 

 to be of no importance; whilst 31 species are only quite accidentally met 

 with ; 14 species belong more especially to the Venetian fauna, yy species to 

 the Dalmatian fauna, and 29 species are exclusively and only occasionally 

 cauoht on the southern shores of Dalmatia ; 5 species belong specifically to 

 the Adriatic fauna. Only 100 species have a recognised commercial value,
