MEMOIR OF THE LATE FREDERICK BOND. 419 
erythrina (a female bird), taken at Hampstead, Oct. 5th, 1870, 
and figured by Gould in his ‘ Birds of Great Britain’; a Bull- 
_finch of a smoky white, obtained at Hampton Court in 1875; a 
very curious variety of the Hawfinch, nearly white, with black 
wings and tail, caught at Denmark Hill, and presented by 
Mr. K. Bidwell ; an abnormally-coloured Yellowhammer, taken 
in Hackney Marshes in 1872; a pied Linnet, caught also near 
London ; and a singular variety of the Chaffinch, with the head, 
neck, and part of the wings and breast white, obtained at Staines 
in 1880. So much for this unique cabinet. Then we have a 
white Partridge, shot at Brandon in September, 1856 (Case 36) ; 
a white Knot, Tringa canutus (Case 47); four very curious 
varieties of the Common Snipe, and one so-called Sabine’s Snipe 
(Case 47), regarded by the owner as a melanism of the common 
species (Zool. 1862); an albino Black-headed Gull, Larus ridi- 
bundus (Case 58); two Puffins, one white, the other pied (Case 
71); and (amongst the collection of skins) a pure white female 
Hider Duck (ef. Yarrell, ‘ Brit. Birds,’ 4th. ed. vol. iv. p. 462). 
It is a curious fact that although the young of most, if not 
of all, hawks are clothed with white down when first hatched, 
they very rarely grow up white, and indeed an albino specimen 
of any diurnal bird of prey is so seldom met with, notwith- 
standing the numbers of hawks shot and trapped by game- 
keepers, that ‘‘ when found” it deserves to be ‘‘ made a note of.” 
There is a white, or rather cream-coloured, Sparrowhawk in this 
collection (Case 18), which was purchased at the sale of the late 
Dr. Crisp’s Museum, on May 12th, 1884, but no particulars have 
been noted as to when and where it was procured. At the moment 
of writing we can only call to mind two other cases of albinism 
amongst the Falconide. Mr. Howlett, the birdstuffer at New- 
market, in 1865, had a white Kestrel, F’. tinnunculus, which was 
shot that year on Newmarket Heath; and he afterwards preserved 
a white Sparrowhawk, shot at Garely in 1876, which, if we 
mistake not, is now in the collection of Mr. John Marshall, of 
Belmont, Taunton. 
Next to the “varieties” may be-mentioned the ‘‘ hybrids,” 
which, although not numerous, are some of them extremely 
curious. Amongst these may be noticed a cross between the 
Mallard and Pintail, and Teal and Wigeon (Case 38), and a 
hybrid duck, purchased at Mr. Doubleday’s sale at Epping,
