As I havesome fine specimens, sent me by Mr. Wheelwright, Ihave much pleasure in doing so. At first sight it would be difiicult for anyone whohad not seen much of the northern race, to find anyreal distinction between the two birds; but Mr. Wheel-wright has given several points in which they constantlydiffer; and it will be found by the following letter,from the celebrated ornithologist, Lilljeborg, that theseare not only constant, but, as he expresses it, are asmarked as ths differences between several other birdsof acknowdedged specific distinction.

Nearly always I have foundthe wi
