422. Iole olivacea lonnbergi

(422) Iole olivacea lonnbergi.

THE SIAM BULBUL.

Criniger lonnbergi Gyldenstolpe, Kung. Sven. Vetensk. Handl., 50, No. 8, p. 24 (1913)" (Bang-hue-hom, N. Siam).

Vernacular names. None recorded.

Description. This race differs from I. o. virescens in having the under tail-coverts cinnamon instead of yellow and from cinnamomeoventris in being more yellow below and more green above. From both of these subspecies it differs 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 uncommon in some places in North Siam, frequenting dense primeval forests in small flocks.
