Distribution. Sangi Islands: — Great Sangi (v. Rosenb. a 2, Hoedt a 2, Bruijn b 1, Platen 2, 
Nat. Coll.); Siao (Hoedt a 2, v. Duivenb. a 2, Meyer, Nat. Coll.); Tagulandang’ 
Ruang and Biarro (Nat. Coll, in Dresd. and Tring Mus.); Talaut Islands (Nat. Coll.). 
I he Sangi race follows the rule for Sangi in being larger than its fellow- 
species, P. melanospihis, of Celebes; it is further distinguishable by its paler 
yellow gular stripe and slightly darker green plumage; the female likewise has the 
plumage slightly darker green. Under the name P. nuchalis Briiggemann descri- 
bed 11 specimens from lischer and one from Riedel, all said to be from Celebes, 
and Prof. W. Blasius found them to be identical with P. xanthorrhous. It is quite 
incredible that P. xanthorrhous and melamspilus could exist together in the same 
locality and yet keep distinct; their slight differences have certainly arisen under 
separation, and we cannot doubt that the birds w^ould interbreed freely and 
lose them if they met. As in several other cases Briiggemann was led by 
false labels or other causes to record Sangi species from the mainland of 
Celebes, so in this case also some confusion of the kind must have taken place. 
It is interesting to find that the birds on Biarro and Tagulandang are not 
intermediate between the Sangi and the Celebes species, but belong to the 
former; showing that the birds are extremely stationary and that these inter- 
mediate islands must afford the same conditions, whatever they may be, as 
Great Sangi. 'I'he specimens from Great Sangi appear to differ in the green 
shade from specimens of the southern islands. 
In the last few years large numbers frorrr the Talaut Islands have reached 
the Dresden Museurrr and have been closely examined. All that can be said
