between these subspecies can only be seen when series are compared. In general 

 colour there is no difference. Adult birds often (though apjiarently not always) are 

 deep orange, others yellow. The extent of black and yellow in the tail is very variable

49. Ptilinopus melanocephala aurescentior subsp. nov. 

 A large series from the Tukang-Besi Islands differ from P. 'melanocephala, 

 melanospila Salvad. of Celebes in being much more golden-yellowish on the back, 

 neck and chest. They are evidently more similar to P. melanocephala melanocephala 

 of Java and the Lesser .Sunda Islands, but differ in the .smaller black occipital patch 

 and generally slightly darker yellow gular patch. They must therefore be separated 

 under a .special name, if all the other hitherto recogui.sed forms are separated. They 

 are all subspecies of one species, and may be reviewed as follows : — 



1. P. melanocephala- melanocephala (Forst.) (Columbn melanocephala Forst., 

 Zool. Inch, 1781, p. 16 PI. VII.) : Back, sides of neck and chest strongly waslied wilh 

 golden yellow, black nuchal patch large, size smaller, yellow gular patch generally 

 lemon-yellow. Vent deep yellow. Java, Bali, Lombok, Sumbawa, Sumba, Satonda, 

 Flores, Djampea, Kalao and Salejer. 



2. P. melanocephala aurescentior Hart. (sub.sp. nov.): Back, sides of neck and 

 chest strongly washed with golden-yellow, black nuchal patch decidedly smaller than 

 in No. 1, size smaller (the same as that of No. 1), yellow gular patch generally 

 slightly deeper yellow, vent deep yellow. Tukang-Besi Islands, Buton (? S. Celebes).® 

 Type No. 4567, c? Kalidupa 7. i. 1902, Kiihn coll. in Mus. Tring. 



3. P. melanocephala bani/iieijensis Jley. (PtiJopus hangueyen&is Meyer, J. f. (I. 

 1891 p. 70, Banguey). Elntirely similar to No. 1, the gular patch not at all larger, 

 this when supposed to be the case being <Iue to preparation, but wing often about 

 5 mm. longer. Southern Philippines and Sulu archipelago. (.4 very poor and hardly 

 separable form, much less distinct than No. 2.) 



4. P. mel anocephal a ■melanospila (Salvad.) (lotreron melaiwspnla Salvad., Ann. 

 Mas. Civ. Gen. vii. 1875. p. 671, Celebes). Much less tinged with yellow, otherwise 

 like No. 1. Celebes. 



5. P. melanocephala chrijuorrhoa (Salvad.) (lotreron chnjsorrhoa Salvad., Ann 

 MuH. Civ. Gen. vii. 1875. p. 671, Sula & Ceram). Nuchal black patch very narrow, 

 gular patch and vent deep orange, green with a yellow tinge, often as strong as in
