 (Edward) ; appearing in the Firth of Forth at the end of July, and disappearing 

 about August (Parnell). Also round the English and Welsh coasts, as off 

 Cumberland (Heysham), Yorkshire (Yorkshire Vertebrata), Yarmouth not 

 uncommon (Paget) ; the Thames and along the south coast as far as Cornwall, 

 where, observes R. Conch, the " twaite shad" Alosa finta, or " Daming-herring," 

 is found in the west part of Cornwall in rather large numbers towards the latter 

 part of the summer pilchard fishery and early in the autumn mackerel fishery. 

 Frequently taken in mackerel drift-nets off Scilly, moving E. or W.E. 



In Ireland it is taken chiefly along the south coast where a few occur annually, 

 but occasionally in great numbers. It has been recorded from Belfast Bay ; 

 Newcastle, Co. Down; Youghal ; south-west of the County of Cork and 

 Galway, Dublin, and is common in northern rivers (Andrews). Likewise Black- 

 water (Ball), and Donegal, where 2 or 3 have been taken (Thompson). It 

 attains to 16 inches (Yarrell), it never exceeds 2 lb. in weight.
