Male. — Forehead and anterior part of the crown liluish grey, 

 darkening to dull brownish grey on the occiput and mantle ; back, rump 

 and upper tail coverts chestnut, duller on the back ; starting from in 

 front of the eye and reaching as far as the hind neck a glossy black 

 superciliary streak, broadening posteriorly, the feathers somewhat 

 elongate ; loral region dark grey ; ear coverts grey with a tinge of 

 brown ; a white ring round the eye ; under surface silvery grey, bluish 

 on the breast and white on the centre of the abdomen and under tail 

 coverts ; tibial feathers glossy black ; tail feathers black, all but the two 

 centre pairs broadly tipped with white and with a narrow edging of white, 

 extending some distance up the outer webs ; primaries glossy l)lack, 

 the innermost narrowly tipped with chestnut on their inner webs with 

 a speculum of greyish blue on the outer webs, and another white one 

 on the inner webs, extending just beyond the shafts ; the primaries, 

 secondaries and tertiaries broadly tipped with white which extends 

 some distance up the shafts, the white tips succeeded by an ill-defined 

 band of greyish blue ; remaining primaries, with the terminal portion 

 of the shaft, white and very narrowly tipped with blue ; secondaries 

 similar to the inner primaries, but a much broader band of chestnut on 

 the inner web : tertials chestnut, blackish basally ; wing coverts glossy 

 black, the lesser ones along the angle of the wing dark l)luish grey ; 

 under wing covei'ts black ; axillaries white. 



" Iris greenish lirowu, mottled with golden specks ; eyelid and 

 base of mandible for about ^ in. liright gamboge yellow ; bill pale 

 bluish white, tip and lateral edges whitish ; feet pale greenish chrome; 

 claws milky blue." — (A. L. Butler). 



Total length, 62 in. (158 mm.) ; wing, 3.5 in. (89 mm.) ; tail, 2.0 

 in. (65 mm.) ; tarsi, .75 in. (19 mm.) ; bill culmen, .62 in. (16 mm.) ; 

 bill gape, .93 in. (24 mm.). 



Female. — Similar to the male, but with a gorget, interrupted mesi- 

 ally, on the lower neck, formed by glistening white tips to the feathers. 



Immature Male (half grown). — Almost identical with the adult 

 male, but with the occi])ut browner and the chestnut on the tei-tials less 

 developed; legs in dried skin pale yellowish, not dark greenish. 



One of the most noticeable features in birds of this genus is the 

 curious form of the outer primaries, which are abruptly truncated at 

 the tip with the shaft extended for about 4 in., forming a sharp point. 



Specimens Examined. — Five, Ginting Bidei, Selangor, 2,300 ft. 

 (May and November), from bamboo jungle. 



Until these specimens were obtained in November, 1907, this very 

 beautiful species was known only from the three original specimens 

 obtained by Mr. Butler on the Larut Hills between 2,500 and 3,500 ft.
