PYCNONOTUS. AL QL 
much paler and with ear-coverts wholly silvery-white. It is 
much less green both on upper plumage and on wings and tail 
than plumosus. 
Colours of soft parts. Iris varies from yellowish brewn to red ; 
eyelids plumbeous ; bill brown, paler at base of lower mandible and 
gape; mouth flesh-colour; legs plumbeous, claws horn-colour. 
Measurements as in the other races. Wing 85 to 89 mm.; 
culmen about 15 mm. 
Distribution. Practically the whole of Burma, North of Ran- 
goon, the Kachin Hills, North and Central Siam, Shan States 
and Annam. 
Nidification. Similar in every way to that of the last bird. 
Eggs and nests are indistinguishable and the clutches are the same 
in number, ¢.e. two or three. As a series they are even more 
poorly marked than those of Robinsou’s Olive Bulbul. Forty eggs 
average 20°6 x lo*7 mm. 
The breeding season must be very extended, as eggs have been 
sent me taken from early March to late August and, probably, 
like most of the common Bulbuls, they breed more or less through- 
out the year. 
Habits. Those of the last bird. They are said to have a very 
harsh note when disturbed and like all Bulbuls under these cir- 
cumstances, erect their crests as they make the eall.

Pycnonotus simplex Less., Rev. Zool., 1839, p. 167 (Sumatra) ; 
Blanf. & Oates, i, p. 292. 
Vernacular names. None recorded. 
Description. Upper plumage brown with a greenish tinge, 
slightly fulvous on the rump and upper tail-coverts; wings and 
tail brown, the outer webs washed with greenish; whole lower 
plumage buffy-brown, slightly streaked in places with darker 
ochraceous ; under tail-coverts dark ochraceous with paler edges ; 
under wing-coverts and edge of wing pale cchraceous. 
Colours of soft parts. Iris orange-red, pale red, whity-pink ; 
upper mandible dark horny-brown, lower mandible paler; legs and 
feet fleshy- or reddish-brown. 
Measurements. About the same as plumosus. Wing 80 to 
88 mm.; culmen about 15 mm. 
Distribution. ‘'enasserim, from Mergui, South through the 
Malay Peninsula to Sumatra. The Javan form has been separated 
by Hartert (Nov. Zool. ix, 1902, p. 561) as P. prillwitzi and the 
Bornean form also seems different from the Malay bird. 
Nidification. Nests aud eggs taken by Mr. Kellow at Simpang 
in the Malay States were, like those deseribed by Davison, taken 
in thick jungle in high bushes. They are rather more richly
