Note see Note 74 — NOTES ON CERTAIN FISHES AND MARINE ANIMALS FOUND IN NORFOLK.

[74] It is quite evident that the fish referred to here, and again in the sixth letter to Merrett, is not the true Bleak (Alburnus lucideus) of our freshwaters. It seems that the young of some species of Clupeoid was thus known, for I find it stated in a MS. note in a copy of Berkenhout's "Outlines of the Natural History of Great Britain," (1769), in the possession of Mr. T. E. Gunn, that the Bleak and the Sprat are often caught together in the sea at Aldeburgh (Suffolk) in November, and the writer of the note adds, "the Bleak is larger than the Sprat, its eyes are larger, and the upper part of its belly serrated." I think from this description and from Browne's remarks, that the young of a species of Shad must have been mistaken for the Bleak, which although found low down in our rivers almost to where the salt tide mingles with the fresh, does not I believe enter the salt water.
