During my scven months trij) to tho North of Siarn I never obseryed a single 

 spccimen, but during my previous journey 1911 — 1912 I oncemel witlia small flock 

 near thc town of Muang Pré. 



This beautiful Bulbul lias rathcr a pretty song which is frequently uttered. 



It is never found in dense jungles but affects cultivated land and orchards.

 mm. — Irides: white. Bill: horn colour. Legs: brown. 



The Olive Bulbul was only obtained in the Siamese Malaya. Here it occurred in 

 the dense forests among the hills dividing Siarn and Tenasserini. Near the coast I 

 never observed it not nor was it very common on the Tenasserini boundary at least not at 

 the localities visited by the Expedition.

This species was originally described from Träng in Lower Siarn (Richmond. Proc. 

 U. S. Nat, Mus. Vol. 22. 1900 p. 320) and given a specific rank. 



As far as I can see, it is only a subspecies of Criniger gutturalis which it resembles 

 very much, being merely separated by its larger size and its paler and more olive colouring 

 on the upper parts of the body; the under parts of the body are darker and less yellow, 

 these parts being almost buffy olive. 



This Bulbul occurred in Northern Siarn, where I found it at the same localities 

 as Criniger gutturalis henrici, Oust.; though it was by no means as common as that 

 species. 



The immature bird resembles the adult one in the general tone of the plumage, 

 but it has the wing-coverts and the secondaries rufous buff and that colour almost occupies 

 the whole of the outer secondaries; the colour of the irides and that one of the bill is also 

 different as stated above.
