Several species of fresh-water Hydrobia (Bithynella) occur. The district, on the whole, unites certain characteristics derived from northern Italy with those of eastern Spain.
(iii) The Italo-Dalmatian district includes Italy and the neighbouring islands (Corsica, Sardinia, Sicily, Malta), and the regions at the head and north-eastern shores of the Adriatic (Carinthia, Carniola, Croatia, and Dalmatia), the line which separates these latter districts from the fauna of southern Austria, Bosnia, and Servia being very difficult to define.
