Vernacular names. None recorded.
Description. Forehead and crown yellowish white or yellowish grey; back of the neck vinous rufous; hack and scapulars ashy-greenish black; lower rump buff; tail black with broad buff tips ; wing like that of G. burmanica but with the white greater in extent and more conspicuous; chin and throat albescent; breast, flanks and abdomen rosy vinous ; vent and under tail-coverts pinkish buff; axillaries and under wing-coverts rosy white.
Colours of soft parts. Iris pearl-white to bluish grey; bill yellow, reddish at the base; legs and feet yellow to tan.
Measurements. Total length about 250 mm.; wing 120 to 130 mm.; tail 70 to 75 mm.; tarsus about 32 mm.; culmen about 21 to 22 mm.
Young birds have the crown of the head brown and the whole plumage duller.
Distribution. Cochin China, Siam and Tenasserim. Hume's incognita cannot be sustained, as the specimens to which the name wis given are undoubtedly nothing more than young examples of G. leucocephala, similar specimens having been obtained all over the range of that bird. A specimen procured " near Perak " and sent to me for identification was undoubtedly of this species.
Nidification. Eggs sent me with a specimen of this species from "near Perak" are like small eggs of the preceding bird and measure between 25.0x19.5 and 26.9 x 21.0 mm. They were taken on the 19th of May and the 25th of April.
Habits. Apparently similar to those of Gracupica burmanica.
