brown, tinged with rufescent on the rump and upper tail-coverts ; 
tail rufescent-brown ; wings brown, the visible portions suffused 
with olive; lores aud sides of the head ashy-brown; chin and

washed with fulvous; abdomen, vent and under tail-coverts dusky

Colours of soft parts. Iris crimson, an ophthalmic ring vivid

Measurements. Length about 165 mm.; wing 70 to 78 mm. ; 
tail about 75 mm.; tarsus about 15 to 16 mm.; culmen about

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. 
Genus MICROTARSUS Eyton, 1839. 
The genus Microtarsus may be recognized by its very ample and 
lengthened tail-coverts, rounded tail and the extraordinary 
development of the feathers of the lower back and rump, which 
are moreover barred with black; in this respeet MJicrotarsus 
shows great affinities to Pinarocichla. 
In this genus the feathers of the head, though erectile, are 
exceedingly short and glossy. The bill is about half the length of 
the head, and the rictal bristles are well-developed. The tarsus 
is very short but fairly stout. The plumage of all the known 
species is very pleasing. 
* Sharpe shows that P. pusi//us of Salvadori, 1874, is preoccupied by 
Gray, Genera Birds, i, p. 237, and cannot be used. He therefore proposes 
(Cat. B. M., 1881, Appendix, p. 401), P. salvadorii, but though this stands as 
the name for the Sumatran race, erythropthalmus of Hume has priority as the 
specific name.
