Examples taken on Doi Hua Mot between August 19 and 26 are in 

 postnuptial molt. 



Adults have the irides dark red-brown ; the maxilla plumbeous, with 

 the culmen and tip black ; the mandible plumbeous ; the feet and toes 

 flesh ; the claws horn. 



The old male has the forehead chestnut, followed by a band of 

 bright yellow across the f orecrown ; the remaining upperparts bright 

 olive-green ; the shoulders black, with two broad white bars ; the rest 

 of the folded wing bright olive-green, except that the outer primaries 

 are edged with white along the outer web and the secondaries are nar- 

 rowly tipped with the same color; the central pair of rectrices bright 

 olive-green, the others black with an outwardly increasingly broad 

 white tip, the outermost pair almost wholly white ; a broken eye ring 

 of pure white feathers ; the lores and a narrow line edging the lower 

 half of the eye ring black ; a streak from above the eye to the sides of 

 the nape ashy, darkening posteriorly ; the chin and throat chestnut ; 

 the under wing coverts pure white; the flanks and thighs grayish 

 white; the remaining underparts bright yellow. The adult female 

 differs chiefly in having the forehead chestnut-rufous, immediately 

 followed by the olive-green of the remaining upperparts ; the shoulders 

 olive-green, with two salmon-buff bars ; the black line below the eye 

 merely indicated ; the chin suffused with rufous ; the remaining under- 

 parts grayish white, washed with pale yellowish olive on the breast, 

 flanks, and abdomen ; the under tail coverts light yellow.

 (PhuKha). 



The only example yet known from Thailand is an adult female, col- 

 lected by me on Phu Kha, 4,500 feet, April 5, 1936. 



This bird, although accompanied by a male, had the ovaries still 

 quite inactive. 



The adult male differs from that of the preceding species most con- 

 spicuously in having the forehead bright yellow; the ashy streaks 

 from above the eyes joined in a broad band across the nape ; the bright 

 yellow ear coverts bordered posteriorly by a black vertical band. The 

 adult female differs from that of P. a. intermedins in having the entire 

 upperparts (including the forehead) olive-green, except for a gray 

 nuchal band ; a black band indicated behind the ear coverts ; the sides
