upper wing-coverts bright lemon chrome; feathers of lower back, 

 rump, and the upper tail-coverts with the edges pale light yellowish 

 olive to almost white, producing a sparsely streaked appearance; 

 rectrices dark olive brown, partly edged with ecru olive, paler at the 

 base, the three outer pairs partly dusky whitish on their inner webs, 

 the three median pairs with narrow pale buffy brown to buffy whitish 

 edgings on their inner webs only; sides of head dingy drab grayish 

 white with a faint olive tinge, the auriculars similar but darker, hair 

 brown to dark grayish olive; chin whitish, throat and breast similar 

 but washed with olive gra3-ish to ashy buff; rest of underparts dirty 

 white, tinged with grayish buff on the abdomen and under tail- 

 coverts; feathers of flanks and thighs with broad shaft stripes of dull 

 blackish brown; under wing-coverts creamy white with brownish 

 shafts; iris crimson (also described as Indian red and as bright scarlet), 

 bill dark horn brown, duskier terminally (also described as dark gray 

 on the maxilla, pale gray on the mandible); tarsi and toes variously 

 described as dark gray, blue, or leaden green, with slate claws. Meas- 

 urements in millimeters: wing 91.5-101.6, tail 65.5-71, culmen, from 

 base, 14-14.8, tarsus 14-14.3.^^ 



Adult female: Similar to the male, but without the yellow band 

 on the lesser upper wing-coverts, and somewhat smaller in size. 

 Measurements in millimeters: wing 86.4-89, tail 56.5-66, culmen from 

 base 11.8, tarsus 12.7. 



Juvenal: "Similar to the adult, but differs in having the upper 

 parts slightly more washed with yellow, with a mere trace of the 

 yellow shoulder-spot; tail identical in colour; throat faintly striped; 

 lower throat and chest less ashy and slightly washed with yellow." 

 (Shelley, in Catalogue of the birds in the British Museum, vol.19, 

 p. 4, 1891; based on Sharpe's description of /. malayanus, now con- 

 sidered to be a young /. archipelagicus. In view of the fact that the 

 adult female lacks the yellow shoulder patch, it would seem that 

 Sharpe's bu'd, which was unsexed, was probably a young male.) 



Natal down: Unknown, if any; color of skin and soft parts un- 

 known. 



31 Chasen (1941, p. 42) gives wing measurements of five males from Borneo as 

 89-94 mm., of two from Sumatra as 98-100 mm., and two from the Malay Pen- 

 insula as 98-102 mm., of two females from Borneo as 84-91 mm., one from Su- 

 matra as 86 mm., and three from Malay Peninsula as 85-89 mm. He notes that 

 a male from Pahang, Malay Peninsula, differs from Bornean and Sumatran males 

 in its more robust bill and slightly grayer, less ohve crov/n. The Sumatran male 

 has grayish streaks on its throat, but aU the differences are sHght.
