(422) lole olivacea lonnbergi. 

 THE SIAM BULBUL. 



Criniyer lonnberyi Gyldenstolpe, Kung. Sven. Vetensk. Handl., 50, 

 No. 8, p. 24 (1913) (Bang-kue-hom, N. Siam). 



Vernacular names. None recorded. 



Description. This race differs from /. o. virescens in having the 

 under tail-coverts cinnamon instead of yellow and from cinnamo- 

 meoventris in being more yellow below and more green above. 

 Prom both of these subspecies it difl'ers in being much larger with 

 a wing of 83 to 89 mm. 



Measurements. Wing 83 to 89 mm. ; culmen 15 to 15'5 mm.; 

 tarsus 15-5 to 16'0 mm.; tail 76 to 83-5 mm. (Gyldenstolpe). 



Distribution. This is a Northern form of the last bird but the 

 limits of neither are as yet definable. Gyldenstolpe found it in 

 N. Siam and specimens from the Shan States and Yunnan are 

 also referable to this form. It will probably also be found in the 

 S.E. Kachin States. 



Nidification. Unknown. 



Habits. Gyldenstolpe records that he found it shy but not un- 

 common in some places in North Siam, frequenting dense primeval 

 forests in small flocks.

Colours of soft parts. Legs and feet dark horny, greenish 

 brown or greenish plumbeous ; bill deep horny-brown, lower

Measurements. Length about 200 mm. ; wing 96 to 103 mm. ; 

 tail about 95 mm.; tarsus about 18 to 19 mm.; culmen about 

 20 mm. 



Distribution. The Nicobar Islands of Teressa, Bompoka, Tillan- 

 chong, Camorta, Nancoury, Trinkat, Katchall and Pilu Milu. 



Nidification. Unknown but as Davison shot very young birds 

 in February, they presumably lay about November to December.
