The Norfolk Island Pigeon, _Hemiphaga spadicea spadicea_, is very similar
to the New Zealand Pigeon, _Hemiphaga spadicea novaezealandiae_, but
differs in having the hind-neck coppery or metallic green, sharply defined
from the chestnut back, the wings and upper wing-coverts more greyish, less
greenish, also the lower back and rump somewhat more greyish.
As far as we know this pigeon was only found on Norfolk Island, the
locality "Australia" being doubtless erroneous. Like so many other birds it
became extinct on Norfolk Island, probably more than half a century ago.
There are evidently quite a number of specimens in various museums, many of
which have never been recorded. I am aware of the following examples:
1 in the British Museum (Cat. B. Brit. Mus. XXI, p. 238).
3 in the Liverpool Museum (Bull. Liverp. Mus. I, p. 35).
1 in my own collection (Proc. IV. Orn. Congress, p. 215).
1 in Philadelphia, U.S. America (Cassin, U.S. Expl. Exp. B, p. 225).
1 in Frankfurt a.M. (Hartert, Kat. Vogelsamml., p. 189).
1 in Wiesbaden (Lampe, Jahrb. Nassau Ver. 58).
1 in Bremen (Hartlaub, Verz. Museum, p. 98).
1 in Lisbon (Forbes and Rob., Bull. Liverp. Mus. II, p. 130).
1 in Leyden (Schlegel, Mus. Pays-Bas).
1 in Vienna (Ibis 1860, p. 422).
1 in Naples, seen by myself.
1 in Milan, examined by myself.
The specimen at Tring was bought at the auction of the "Cumberland Museum"
at Distington.
