Description. The whole upper plumage and wing-coverts olive-brown, tinged with rufescent on the rump and upper tail-coverts; toil rufescent-brown ; wings brown, the visible portions suffused with olive; lores and sides of the head ashy-brown; chin and throat ashy-white; breast and sides of the body ashy-brown washed with fulvous; abdomen, vent and under tail-coverts dusky yellow; under wing-coverts and axillaries pale ochraceous yellow.
Colours of soft parts. Iris crimson, an ophthalmic ring vivid orange-yellow but this withers away in skins and is not discernible; bill black, gape and base of lower mandible and nostrils orange-yellow ; legs, feet and claws pale reddish-horny.
Measurements. Length about 165 mm.; wing 70 to 78 mm.; tail about 75 mm.; tarsus about 15 to 16 mm.; culmen about 13 to 14 mm.
Nidification and Habits. According to Davison this Bulbul differs in no way from the various races of P. plumosus.
The few eggs of which measurements have been obtainable measure about 21.0 x 15.9 mm., but a larger series would certainly give a smaller average for the eggs of this small bird.
