Coloration. Upper plumage black; lower plumage blackish brown; under tail-coverts pure white, the bases blackish ; tail black broadly tipped with white ; wings black glossed with bronze; the primaries with a large patch of white near their bases and the primary-coverts white with black bases. The feathers of the head are very narrow and pointed, and the frontal plumes are about three quarters of an inch long or more.
Iris pale chocolate; bill orange-yellow; legs dusky yellow ( Wardlaw Ramsay). Iris light reddish to orange-brown or hazel (Hume).
Length 10 ; tail 3.5; wing 5.2 ; tarsus 1.5 ; bill from gape 1.3.
Distribution. Manipur; the neighbourhood of Bhamo; Karennee; Tenasserim river. Found also in Siam and Cochin China. Moore's types of this bird are labelled as having come from Sumatra, but this locality is probably wrong.
The Length of the frontal crest varies considerably. Tenasserim and Karennee birds have the crest of great Length, but in Manipur specimens it is much reduced.
AS. cristatellus from China is closely allied, but differs in having the frontal crest of a somewhat different character, the under tail-coverts black with white tips and narrower tips to the tail-feathers.
Habits, &c. Hume describes this bird as feeding with A. tristis and other Mynas on trees. It apparently breeds in Manipur.
