Adult female. Length 9-5 to 9'7 inches ; w’ing 4-5 to 4'75 ; tail 4-5 to 4-75. 
Iris varying from reddish brown to brownish red, in some obscure red ; bill, legs, and feet black. 
Obs. These measurements and the colours of the soft parts are taken from a series of northern and southern examples, 
the representatives of the two types into which this species apparently divides itself ; but in order to the more 
complete insight into the question, I will in my “ descriptions ” first deal with one type, and then pass through 
the intermediate form to the other. 
Bark form: Buchanga leucopygialis, Blyth. 
Adult male (Wellewatta, Colombo). Wing 4-75 inches ; tail 4-0 ; bill to gape 1-0. 
Iris dull red. 
Head and entire upper surface black, illumined wdth steel-blue ; wings and tail brownish black, with a metalHc lustre, 
slightly greener than that of the back on the outer webs of the feathers ; ear-coverts and face black, without the 
metallic lustre of the head ; chin, fore neck, and chest dull black, intensifying somewhat on the chest, and slightly 
glossed in that part ; on the breast the centres of the feathers become gradually brown, with the edges iron-grey, 
the latter paling to greyish white lower down, and thence into white on the abdomen, giving that part, however, 
only a whitish appearance on account of the dark centres of the feathers ; vent and under tail-coverts white. 
Adult male (Mapalagama, South Ceylon). Wing 4'85 inches ; tail 4-9 ; bill to gape I'O. 
Iris obscure red. 
Much darker on the lower breast and belly than the above, as it is in abraded plumage, and the whitish edgings are 
worn off from this cause ; the vent is only greyish white, and the under tail-coverts sullied white ; gloss on 
the upper surface duller, or not so green as in the freshly-moulted specimen. 
Adidt female (Poorie, W. Province). Wing 4-55 inches ; tail 4-4 ; bill to gape I'O. 
Iris dark red-brown. 
In more abraded plumage than the last ; the entire breast and belly dull brown, the vent greyish, and the under tail- 
coverts greyish white.
