frontal patch, the occiput tinged with yellow and a yellow 

 border all round the black area of the throat ; an immature 

 female with a green chin and black throat has the frontal 

 region deep yellow, but shows distinct promise of a yellow 

 collar (wings 84-90 mm.).

Erroneously supposed in the first instance to have come 

 from the Sandwich Islands, Sumatra has recently been 

 designated as the type-locality (Oberholser, Smithsonian 

 Misc. Collections, Ix. No. 7, p. 10, footnote). I cannot find 

 any differences between Sumatran, Malayan, and Siamese 

 birds.

The wings of a pair of topotypes from Buitenzorg are 

 85 mm. long, whereas those of Sumatran and continental 

 birds are often over 90 mm. A larger series from Java 

 would probably show that no difference in size exists; the 

 colour of all is alike. Freshly moulted birds are sometimes 

 very dark, especially on the breast.
