[A Scotch form of pollan, the two fishes being formerly identified.]
A species of fresh-water fish, Coregonus clupeoides, found in Loch Lomond in Scotland (where locally known also as Luss Herring), in Windermere and Ulleswater (where known as the Schelly), in Conningham Mere, and in Bala Lake (where called Gwyniad). It belongs to the same genus as the Vendace and the Pollan, with which it was formerly identified, and is still often confused, under the name Freshwater Herring: see quots. 1774–7.
