Distribution. Sangi Islands: — Great Sangi (v. Eosenb. a 2, Hoedt a 2, Bruijn b 1, Platen 2, 

 Nat. Coll.); Siao (Hoedt a 2, v. Duivenb. a 2, Meyer, Nat. Coll.); Tagulandang, 

 Euang and Biarro (Nat. Coll. in Dresd. and Tring Mus.); Talaut Islands (Nat. Coll.). 



The Sangi race follows the rule for Sangi in being larger than its fellow- 

 species, P. melanospihs, 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. vuchalis Briiggemann descri- 

 bed 1 1 specimens from Fischer 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 melanospilus 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 would 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. The specimens from Great Sangi appear to differ in the green 

 shade from specimens of the southern islands. 



In the last few years large numbers from the Talaut Islands have reached 

 the Dresden Museum and have been closely examined. AW. that can be said
