Turning to the pisccs, we find 316 species of sea-fishes, belonging to 137 

 genera, 51 families; and 66 species of fresh-water fishes, belonging to 27 

 genera, and 14 families, which are found in the watershed of the Adriatic. 

 This gives a total of 3S2 species belonging to 161 genera, 57 families, 10 

 orders, and 4 sub-classes. 



Of the fresh-water fishes, 2 1 species (belonging to 9 families) are also 

 common to the sea ; they either prefer the brackish waters, such as the Pike, 

 the Sticklebacks and Cypriuodon ealaritauus, also 2 Gobies (G. panizzee,
