Itys
Itys in Britain, mentioned by Ptolemy (2.3.1) as a river lying north of the Epidian promontory (Mull of Cantyre), with the river Longus between. As this latter==Loch Linnhe, the Itys is probably the Sound of Sleat, between the Isle of Skye and the mainland. In the Monumenta Britannica we have Loch Torridon, Loch Dutch, Loch Eu.
