154 BIRDS OF TENASSERIM. 



more orange feathers appear, and then red ones, and by the time 

 the greater portion of the chin and throat are red, the red breast 

 spots begin to show out, and the whole forehead becomes more 

 or less golden. 



But then we have other young birds in which the chin and 

 throat have become red, and the forehead golden orange, without 

 the slightest appearance even of red on the crown ; and others 

 in which the whole crown is red, the chin and throat pure pale 

 yellow, and the whole forehead still green ; and again others 

 in which the whole forehead has become bright yellow, without 

 the appearance of any red on either crown or throat, so that it is 

 clear that there is considerable irregularity in the stages by which 

 the uniform green bird passes into the brilliant plumage of the 

 adult, and I do not, therefore, think that the point on which 

 Messrs. Marshall and Davison are disposed to rely for separating 

 humei, even coupled with the fact that we have never obtained 

 a specimen in Tenasserim or the Malay Peninsula, corresponding 

 exactly with humei, is at all conclusive as to the specific distinct- 

 ness of this latter. It is quite possible, however, that humei 

 may still prove to be a distinct and very closely allied Bornean 

 race, but I personally do not expect this. 



The following are dimensions, colors of the soft parts, and 

 description of perfect adults : — 



Males. — Length, 8*0 to 9*5 ; expanse, 1275 to 13-6 ; tail, 23 

 to 2-62 ; wing, 376 to 4*2 ; tarsus, TO to 1*05 ; bill from gape, 

 1*6 to 1*8; weight, 275 to 3 ozs. 



Females. — Length, 9'12 to 9-25 ; expanse, 13 to 13-5 ; tail, 2-4 ; 

 wing, 3'85 to 4-1 ; tarsus, 0'95 to 1*12 ; bill from gape, T75 to 

 1-8 ; weight, 275 to 3*5 oz. 



Legs and feet very pale bluish or horny green ; irides deep 

 brown; bill black; orbital skin dark greenish or greyish brown. 



The adult has the whole forehead and anterior half of the 

 crown golden yellow ; the posterior part of the crown, and the 

 centre of the occiput crimson ; a spot at the base of the bill in 

 front of the eye ; chin and upper part of throat, and a spot on 

 either sides of the base of the throat, crimson ; cheeks and basal 

 portion of ear-coverts, and basal one-third of throat, blue ; 

 feathers immediately above the eye, and a short broad streak 

 running backwards from the posterior upper half of the eye, 

 black; a patch of bright pale yellow, followed by pale verditer 

 blue, at the base of the lower mandible on either side ; rest of 

 the plumage (except the inner webs of the quills and lateral 

 tail feathers, and the outer webs of the first primary, and of the 

 succeeding primaries below the emavginations, which are deep 

 hair brown) bright grass green, paler on the lower surface, and 

 the feathers of the neck, and more or less of the back and breast, 

 and generally the upper tail-coverts, more or less conspicuously
