Coloration. Resembles 67. burmanica, but has the forehead and crown brownish; back, scapulars, and upper rump ashy black; lower rump buff; hind neck and sides of neck vinous, forming a collar which joins the breast; wings darker, and the primary-coverts entirely white; first primary white. In freshly-moulted birds the forehead and crown are paler than at other times, almost white.
Bill and legs yellow; the former reddish orange at the base; iris brown (Giglioli and Salvadori).
Length about 10; tail 3.2; wing 5.2; tarsus 1.35 ; bill from gape 1.2.
Distribution, Said by Hume to have been obtained on the hills between Tavoy and Siam, and there are numerous specimens in his collection from this locality. This species occurs in Siam, and was first found at Thu Due near Saigon, in Cochin China.
* Poliopsar fuscogularis, Salvadori (Ann. Mus. Civ. Gen. (2) vii, p. 364, 1889), does not appear to be separable from the present species. Thanks to the courtesy of Count Salvadori, I have been able to examine the type, the only specimen known, procured by Mr. Fea in Karennee. This has the chin and throat dark brown and the head and neck brownish, instead of white. These parts are subject to variation in this Myna, and before I can admit P. fusco- gularis to be a distinct species or even race I should wish to examine more specimens in the same plumage. It must be remembered that Wardlaw Ramsay procured typical G. burmanica in Karennee. (See also Sharpe, Ibis, 1889, p. 580.)
