Halford, 16 hand-coloured plates of flies, 3 plain plates and text illustrations, plain green end-papers. Green rexine wallet-style binding, spine & upper cover titled in gilt.

With 16 hand-coloured plates of flies, a facsimile of a 3-page hand-written letter from F.M. Halford to Mosely, and blank notes pages at rear. "The Publishers regret that hitherto they have been unable to find an artist capable and willing to undertake the hand-colouring of the flies figured in this book in such perfection as to meet the standard of meticulous accuracy required by the author for the Author's Edition." It was intended to produce a deluxe Author's Edition at a later date, but this does not appear to have happened. In 1931, new information came to light about the classification and identification of the March Brown. In 1932 the publishers issued an addendum pamphlet (The March Brown: A Correction) describing this. Initially they included this as a loose insert in copies of the book sold. Subsequently, as further copies of the book were bound, (presumably using the original sheets from 1921), this pamphlet was bound into the book between pages 36 and 37. Some copies have the whole pamphlet bound in (4 leaves including a title-page and advertisements at the rear) while others just have the 2 leaves (4 pp) of text bound in. * This copy has the whole of the addendum pamphlet bound in between pages 36 and 37. "The hand-coloured figures...seem to us to be very near perfection as exact representations." (The Field). "It should be in the library of every naturalist and of every fisherman." (The Shooting Times).
