GWYNIAD  , the name given to a

fish of the genus Coregonus or White fish (C. clupeoides), inhabiting the large lakes of North Wales and the north of England . At Ullswater it is known by the name of " schelly," at Loch Lomond by that of " powen." It is tolerably abundant in Lake Bala, keeping to the deepest portion of the lake for the greater part of the year, but appearing in shoals near the shores at certain seasons . It is well flavoured, like all the species of Coregonus, but scarcely attains to the weight of a pound .
