Dr. W. L. Abbott collected: Five males (one immature) in Trang 

 (Prahmon, February 24-March 17, 1896; Trang, March 4, 1899); 

 and one male, Bok Pyin, Tenasserim, February 16, 1900. He gives 

 the soft parts as: Iris red or dark red; bill fleshy purple or pinldsh 

 flesh color; feet leaden. The immature male had the iris reddish 

 brown; bill dull pinldsh, indistinctly blotched with black patches. 



The majority of Siamese specimens have the black extending across 

 the tail to the outer feather as a bar, but in some there is no black 

 at all on the two outer feathers, and in others it is a mere blotch on 

 the outer web. In fact, this feature is very inconstant and variable, 

 as is also the color of the back in the male. In some it is sulphine 

 yellow, in others almost cadmium yellow. I rather think these differ- 

 ences are due to age. A sufficient series from India has not been 

 available to test out any differences that might exist between it and 

 the populations to the eastward. I am following Stuart Baker ^^ in 

 uniting all the mainland birds under one name. 



The nestling taken by Dr. Smith at Pak Chong, May 4, is barely 

 out of the nest. It resembles the adult female, but the breast Is 

 much lighter, almost white down the center, udth elliptical black 

 spots; the mantle is also spotted with black. 



The form is resident all over Siam proper and extends down Penin- 

 sular Siam as far as the island of Langkawi, where it has been recorded 

 by Robinson. *° 



The whole range extends from India to Assam, Burma, Siam, and 

 Indo-China, and south to Tenasserim and Peninsular Siam as far as 

 Langkawi. Closely related forms occur in Ceylon and northern 

 Borneo.
